SUBSTANCE: invention relates to hydro pneumatic automatic control devices and can be used in aircraft hydraulic control systems. The proposed valve incorporates a body with the pressure, control and drain channels separated by two cups arranged in the valve body and provided with aligned grooves and holes. A push rod is arranged in the said grooves to move therein. The aforesaid holes in the cups are made on both sides of the push rod to contact, by their outer edges, with the ball-like shut-off members. One of the said balls, on the drain side, interacts with a spring-loaded rod moving inside the electromagnetic drive stator. Note that in one position of the aforesaid rod, the control channel communicates with the drain line while, in the other position, it communicates with the pressure channel. There is a spring-loaded plunger fitted in the valve body of the pressure side, its end face interacting with the shut-off member on the aforesaid side. Cylindrical collars are made on the outer surface of every cup on the side of holes and aligned with them. One of the said collar accommodates on the drain side a sleeve locked in a blind groove aligned with the sleeve through hole receiving a ball. The collar of other cup, but on the pressure side, accommodates a similar sleeve with the ball.
EFFECT: higher valve tightness.
The invention relates to a device that can be used in control systems for aircraft, where required by applying an electrical signal to the electromagnetic valve actuator and by moving its organs to change the direction of flow of the working fluid from the discharge line to the control channel hydraulic mechanisms with subsequent connection of these channels drain line.
Known valve, the casing of which there are two glasses, locking bodies in the form of balls, interacting with the edges of the holes in the cups, elastic elements acting on the locking bodies by injection and drain the actuator, electromagnetic actuator, whereby the control cavity is connected to the drain and discharge (see ed. mon. The USSR №579490, CL F16K 31/02, F15B 9/03).
The closest in technical essence is a valve consisting of a housing with a discharge channels, control and drain separated, defined therein two glasses, made coaxially within their bores in which is located with the option to move the plunger, and the holes in the glasses on both sides of the pusher contacting outer edges with locking bodies in the form of balls, one of which is from the side of the drain - interacts with moving inside the stator e is ctromagnetic drive, also posted on the housing, a spring-loaded shaft in such a way that in one position of the control channel communicated with the drain, the other with discharge, installed on the discharge side of the sleeve is placed in her spring-loaded plunger, the end of which interacts with the locking body, which is also on the discharge side (patent RF №2150628).
A disadvantage of the known valves is that the hydraulic mechanisms of the control system, they can not provide the desired tightness of locking bodies within the resource required to provide a given level of reliability in the operation of the aircraft as a whole.
This is due to the following:
1. In the valve according to the patent of Russian Federation №2150628:
- set in the holes of the sleeves of the locking bodies does not provide concentric their fit to the outer edges of the holes because the holes in the bushings and the glasses are not centered relative to each other. This leads to the fact that the balls in the bushes occupy shifted relative to the outer edges of the holes in the glasses of the position, and, as a consequence, to the formation of a gap between them and leakage between the channels of the valve during its operation.
2. The valves on author. mon. The USSR №579490:
- installation of the locking bodies in the holes of the sleeves in the form of constraints on the part magnet the tion, similar to installing them in the valves according to the patent of Russian Federation №2150628, do not provide the required tightness;
- installation of the locking bodies (side drain) into the hole of the spacer, the outer diameter of the centering guide in which your shoulder sends a stop and the glass, improves the location of the ball relative to the outer edges of the holes in the glasses, but does not exclude their mutual displacement, since the spacer with the ball also has the ability to move in the plane perpendicular to the axis of the nozzle holes on the magnitude of the clearance between the outer diameter of the spacers and the inner diameter of the guide.
Reasons preventing this, the lack of known valves of a number of elements and a certain relationship between its constituent parts, as well as their execution, which does not allow to provide conditions for implementation of the specific requirements on tightness.
The technical task of the invention is to eliminate this drawback.
Tasked to ensure the required tightness by locking bodies is solved in that in the present valve, comprising a housing with a discharge channels, control and drain separated, defined therein two glasses, made coaxially within their bores, which are available with the ability to move t lcatel, and the holes in the glasses on both sides of the pusher contacting outer edges with locking bodies in the form of balls, one of which is from the side of the drain - interacts with moving inside the stator magnetic drive, can also be found on the housing, a spring-loaded shaft in such a way that in one position of the control channel communicated with the drain, the other with discharge, installed on the discharge side of the sleeve is placed in her spring-loaded plunger, the end of which interacts with the locking body, which is also on the discharge side, according to the invention on the outer surface of each of the glasses with side holes and coaxially with them is cylindrical piles on one side of the drain is installed with the possibility of fixation through the hollow bore of the sleeve, and this bore is made therein coaxially with the through hole of the sleeve, in which is placed the ball on the shoulder of another glass from the discharge sleeve is made and installed placed in its hole with the ball, similar to the sleeve from the side of the drain.
The essence of the invention is illustrated in the drawing, which presents his General scheme.
The valve includes a housing 1 with channels discharge, control and drain, separated, and placed on elektromagnitnyi 2. In the case set two glasses with 3 coaxial performed within their bores, which are available through the centering sleeve 4, the pusher 5, moving his butt off bodies in the form of balls 6 in contact with the outer edges of the holes 7 of cups 3.
Left the ball 6 from the side of the drain communicates with the rod 8 supported by a spring 9, moving inside the stator 10 of the electromagnetic actuator 2.
The right ball 6 on the discharge side communicates with an end face of a spring-loaded plunger 11, placed in the sleeve 12, also located on the discharge side.
On the outer surface of each of the cups 3 side holes 7 and coaxial with them is cylindrical clamps 13, on one side of the drain is installed can be locked by means of a blind bore 14 and the sleeve 15, and this bore 14 is in her coaxially with her through hole 16 in which is installed the bulb 6. The collar 13 another glass 3 on the discharge side is made and installed, the sleeve 12 is placed in its hole 17 of the ball 6, similarly to the sleeve 15 (side drain).
The operation of the valve is as follows. In the absence of an electrical signal pressure of the working fluid and the plunger 11 with a spring, acting on the right ball 6, press it to the edge of the nozzle holes 3, thereby decoupling the channel in the management of channel discharge. In this case, the pusher 5 press the left ball 6 and the spring rod 8, whereby the control channel is connected with the sink. When enabled, the electromagnetic actuator 2 piston rod 8 moves left, the ball 6 to the right until it stops at the edge of the hole 7 of the left Cup 3, thereby blocking the discharge from the control channel, while the plunger 5 moves right ball, opening the access of the working fluid from the discharge channel in the control channel.
Due to the fact that the shoulders 13 on the sleeves 12 and 15 is coaxial with the holes 7, respectively, and their blind bore 14, respectively, is made coaxial with the holes 16 and 17, are provided with the concentric arrangement of the balls 6 relative to the outer edges of the holes 7 of cups 3 and, as a consequence, the required tightness shut-off bodies.
Thus, qualitatively improves the efficiency of the hydraulic mechanisms of the control system and the aircraft in General.
Numerous studies valves made in accordance with the proposed scheme, fully confirmed their advantage in comparison with the known valves.
