Known electroneurography (RF patent No. 2159383), comprising a housing, an Executive body, the electromagnet with the armature, a latch mounted on the finger and cooperating with the ledge anchor and proryvnuju membrane. Latch support surface on the short arm interacts with a window made in the Executive body.
The disadvantage of this device is its single use. This type of device is used when you want a single operation in one cycle of the product, such as a missile, spacecraft, including reusable, where there is a requirement the Oia minimum weight. In such a device is not provided again after actuation of the switch to its original position, as the membrane is non-reusable. Also in this device prior to installation of the membrane when conducting a verification test operation at the time of Assembly of the possible rotation around the axis of the Executive body from a slight unwinding of the spring when it is stretched. This can lead to the rotation of the support surface relative to the window and further spontaneous firing.
The task of the invention is the creation of electroneurography reusable after its cast to its original position. This allows you to verify the accuracy of the Assembly and its quality when conducting multiple alarms designs and workmanship of components in the collection.
This is achieved by the fact that electroneurography in the first embodiment, comprising a housing, an Executive body, the electromagnet with the armature, a latch mounted on the finger and cooperating with the ledge anchor, unlike the prototype of the actuator is made with the rod, and the axis of the finger is offset from the axis of the valve on the value as determined from the relation: a≥(dW+dp)/2, where dW- stem diameter, dp- the diameter of a finger, while on the long arm of the latch perpe dicosmo axis of the valve is made a groove, interacts with the stem.
The task is also solved by the fact that in electroneurography according to the second variant, comprising a housing, an Executive body, the electromagnet with the armature, a latch mounted on the finger and cooperating with the ledge anchor, unlike the prototype of the actuator is made with the rod, a latch mounted on two coaxial fingers, and the stem of the Executive body is located between them, with fingers axis offset from the axis of the valve on the value as determined from the relation: 0<a<(dW+dp)/2, where dW- stem diameter, dp- the diameter of a finger, while on the long arm of the latch perpendicular to the axis of the valve is made a groove that communicates with the stem.
In addition, the latch may be spring-loaded by interacting with the ledge anchors, and entrance or exit is located on the axis of electroneurography.
The technical result is to increase the reliability of electroneurography by the possibility of its checks on the operation after Assembly. Reliability as the amount, expressed in terms of probability, the higher, the greater the number of responses.

Electroneurography (see figure 1) consists of a body 1, of the Executive body 2 with elastic sealing elements 3, spring 4, the Cup 5, the latch 6, the electromagnet 7, the armature 8, the fitting 9, the sleeve 10. The latch 6 is fixed on the finger 11 in the groove of the sleeve 10. On the long arm of the latch 6 perpendicular to the axis of the valve is made a groove 12 with the supporting surface 13, which is preloaded by a spring-loaded rod 14 spring 4 Executive body 2. On the opposite side of the Executive body 2 by a rod 15 with elastic sealing elements 3 located in the holes of the Cup 5 and the fitting 9 and disconnecting the input and output electroneurography. The rod 15 of the Executive body 2 has a channel 16, which connects the cavity of the fitting 9 and the cavity of the armature 8. The diameters of the holes of the Cup 5 and the nozzle 9 are equal, so the Executive bodies the h-2 is unloaded from the pressure in relation to the input, and exit. This allows the use of the spring 4 less effort that is required to overcome friction efforts elastic sealing elements 3 and move the Executive body 2. At anchor 8 is made ledge 17, interacts with its long shoulder latch 6. Bearing surface 13 of the latch 6 (see Fig.6), which rests against the rod 14 in the initial position, takes the load from the springs 4 force R applied to the Executive body 2 along the axis of the valve. The anchor 8 of the electromagnet 7 is preloaded to the sleeve 10 by a spring 18 having the minimum force required only to return the armature 8 to bring him to the starting position. The anchor 8 is located at a distance from the stop 19 of the electromagnet 7, equal to the length of engagement between the ledge 17 and the latch 6. In the channel 16 from the nozzle 9 is made of the fixing element in the form of, for example, threaded holes 20. The Cup 5 is made ledge 21 to limit movement of the locking member 2 in process operations. The fitting 9 is closed by a nipple 22, preloaded nut 23. In the first embodiment, electroneurography (see figure 2) axis of the finger 11 is offset from the axis of the valve on the value of a≥(dW+dp)/2, where dW- the diameter of rod 14 Executive body 2, dp- diameter of the pin 11. In the second embodiment, the latch 6 is attached to the two fingers 11 (see figure 4, 5)arranged on the same axis, while the axis of the fingers is offset from the axis of the valve on the value a< (dW+dp)/2, where dW- stem diameter, dp- the diameter of a finger, and a≠0. This allows you to bring the point 24 of application of force R to the axis of the finger 11 and to maintain a minimum leverage impact force R relative to the axis of the finger 11. The pivot 24 depending on limiting the application of the efforts of the R surface on the latch 6 in the first and second embodiments (see Figure 2 and Figure 4) can change its position in the range equal to the diameter of the rod 14, and accordingly will change the shoulder of the applied force R relative to the axis of the finger 11. The condition of equality of the moments of forces about the axis of the finger 11 (see Fig.6):
where R is the force of the spring 4,
a - the force arm R.
R1- force-reaction of the ledge 17 of the armature 8 to the force R.
b - the force arm R1at the point 24.
To overcome the efforts of the friction-slip on the strength of R1you want the electromagnet 7 low power and mass. The latch 6 (see Fig.9) can be biased by spring 25 by interacting with the ledge 17 of the armature 8 in the direction of rotation of the latch from the ledge 17. The force of the spring 25 is negligible and no impact on the latch 6 of the rod 14 of the Executive body 2 should provide the torque a little more torque from the weight of the latch about the axis of the finger 11.
Electroneurography works as follows. Filed with the ode (or exit) the pressure in the valve is blocked at the output (input) elastic sealing elements 3, located on the rod 15 of the Executive body 2. To ensure the discharge of the Executive body 2 from the pressure regarding both the input and output is channel 16, and the equality of the bore diameter of the nozzle 9 and the Cup 5, which is the Executive body 2 by the rod 15. When applying voltage to the electromagnet 7 between the armature 8 and the stop 19 there is an effort, which, overcoming the force of spring 18 moves the armature 8 in the gap until it stops in the stop 19. The anchor 8 bench 17 disengages from the latch 6. Accordingly disappears force R1the reaction force of the ledge 17 of the armature 8 to the force R bogatogo Executive body 2 and the rod 14 on the latch 6. The spring 4 moves the Executive body 2 in the direction of the latch 6 and the rod 14 rotates it around your finger 11, overcoming the slight force of the spring 25 when the latch spring made. When turning the latch 6, the rod 14 disengages from the support surface 13. The spring 4 moves the Executive body 2 until it stops at the end of the sleeve 10 (see Fig.7) and outputs the rod 15 of the fitting holes 9, indicating the entrance and exit between them. Valve otkryt electromagnet 7 relieve tension and the spring 18 returns the anchor 8 to its original position. Even a small force of the spring 4, is required to unseat the elastic rings 3, repeatedly lowered the lever, is broken off on the latch 6 due to the large ratio of the shoulders: shoulder b power R 1from the axis of rotation of the latch to its end and the distance between the reference point 24 of the stem 14 and the axis of the finger 11, which is small due to the small diameter of the rod 14 and the finger 11 (valve in the first embodiment). The force of friction-slip from the elastic elements 3 has a value of 0.1 R1. Therefore, to generate electromagnetic force to move the armature 8, a slightly higher amount of friction-slip and the force of the spring 18, is required electromagnet low power and mass.
In the valve according to the second option (see figure 4 and 5), the latch 6 is rotated with two fingers placed on the same axis. The pivot 24 on the surface 13 on which rests the rod 14, is located between the ends of the fingers. This allows you to bring the axis of the shaft to a rotary axis of the latch 6, and accordingly to reduce the shoulder and the force R. In the second embodiment, electroneurography shoulder and the force R is smaller than in the first embodiment, and an electromagnet in the second option requires less power and weight than in the first.
In initial position electroneurography both versions result in the following way. With fitting 9 remove the nut 23 and the nipple 22. In the fitting hole 9 introduce technological screw (not shown)which screw into the threaded hole 20 of the rod 15. Pulling technological screw, move the Executive body 2 until it stops at the ledge 21 of the Cup 5 in this case the rod 15 enters the opening in the fitting 9. Serves the voltage on the electromagnet 7 and under the influence of the magnetic force of attraction of the armature 8 is attracted to the stop 19. In the absence of the turning spring 25 of the latch 6 when casting to its original position to release tension from the electromagnet 7 electroneurography rotate around the axis in a position in which the valve inlet is directed vertically downwards (see Fig), so that under the action of gravity latch 6 is turned to the stop in the housing 1, and then, without changing the position of the valve, relieve tension from the electromagnet 7. The anchor 8 is returned by the spring 18 to its original position until it stops in the sleeve 10. Further repatriation of the Executive body 2 and electroneurography in the initial state may be held in any position. Relieve stress with the process of the screw, the spring 4 moves the Executive body 2 up to the stop rod 14 in the bearing surface 13 of the latch 6. The latch 6 is rotated until it stops at the ledge 17 of the armature 8. Technological turn the screw and removed from the valve. On the fitting 9 install the nipple 22 and the nut 23. Electroneurography shown in its original position. In the second variant, in the presence of the turning spring 25 when the reset rotation of the valve about its axis is not required, since the supply voltage to the electromagnet and the attraction of the armature to stop the spring 25 behavior is no latch in the direction of the axis of the valve until it stops in the housing 1 (see Fig.9). Further repatriation of the Executive body 2 and electroneurography is carried out as in the first embodiment without spring 25. Electroneurography may be performed when removing the nut 23 and the nipple 22 of the fitting 9 is output or input (see figure 10).
Thus, the proposed electroneurography increases reliability due to the possibility of their inspection operation after Assembly, and the possibility of its reuse after bringing it to its original position. This allows you to verify the accuracy of the Assembly and its quality, and when conducting multiple alarms designs and workmanship of the components in the Assembly. In addition, the reliability as the amount, expressed in terms of probability, the higher, the greater the number of responses.
