The web clipper to spray liquid
(57) Abstract:Usage: in the field of mechanization of fluid application. Summary of the invention in the web clipper to spray fluid means changes the efforts of the preload springs are made in the form of the gland bolt with a through axial channel therein for accommodating the stem of the plunger. The stem is made thicker at the opening of the gland bolt end. The cutter is also equipped with a washer installed between the housing and the valve and is made from a material with a low coefficient of friction. The fitting is made with a variety of in excess of its height above the inner pipe drain. 3 C.p. f-crystals, 2 Il. The invention relates to the field of mechanization of fluid application, namely for the design of devices for stopping the liquid flow at the time of the cessation.Known spray with shut-off device, comprising a hollow cylindrical body with a bottom, in which the liquid enters in the direction of its axis and is available through the radial holes. The case is put on the sleeve of elastic material, which closes the radial hole .However, the large size of this device, the inevitable variation in size ciih off valves. Moreover, this design does not provide the change effort (pressure) cutoff.Closest to the proposed clipper is to spray a liquid, comprising a housing, fitting the fluid, the inner axial tube drainage, longitudinally mounted in the nozzle, to form with it the annular channel of the fluid, diaphragm valve for blocking the inlet pipes for drainage, a spring-loaded plunger with a stem for moving the valve means to force changes the preload of the spring .The famous clipper during tilt and rotate the shank of the plunger provides a disabling spray. However, in this case, due to differences in the length and effort of the springs supply and cutoff of fluid in the different nozzles are at different pressures, and at the same pressure at different cut off membrane with valves of different resist liquid, which violates the same flow and make the dose solution. In addition, in some cases, because of the weak spring or sideplane edge of the valve between the body and the membrane cut-off becomes impossible. In addition to the above domestic shutoff prevents temporarily OTC what is the reliability and the possibility of regulating the pressure of the cutter, that will ensure compliance with specified doses of making.The effect is achieved that the cutter to the spray liquid, comprising a housing, fitting the fluid, the inner axial tube drainage, longitudinally mounted in the nozzle to form with it the annular channel of the fluid, diaphragm valve for blocking the inlet pipe drain, spring-loaded plunger with a stem for moving the valve means to force changes the preload of the spring, according to the invention, the tool is made in the form of the gland bolt with a through axial channel therein for accommodating the stem of the plunger.The stem of the plunger is made with a thickening at the opening of the gland bolt end.In addition, the cutter is equipped with a washer installed between the housing and the valve and is made from a material with a low coefficient of friction.The fitting is made with a variety of in excess of its height above the inner pipe drain.In Fig. 1 shows the proposed clipper of Fig. 2 - circuit interrupting height fitting over the inner pipe.The web clipper to spray fluid includes a housing 1, a nozzle 2, the fluid supply, the internal axial pipes of the tee, diaphragm valve 4 to overlap the inlet pipe 3 exhaust fluid, a spring-loaded plunger 5 with the rod 6 to move the valve 4 and the tool changes the efforts of the preload spring 7, which is made in the form of the gland bolt 8 with a through axial channel 9 therein to accommodate the shaft 6 of the plunger 5.The rod 6 is made thicker 10 on leaving the gland bolt 8 the end.The cutter is also equipped with a washer 11, which is installed between the housing 1 and the valve 4, and is made from a material with a low coefficient of friction.The fitting 2 is made with a variety of in excess of its height above the inner tube drainage
The cutter working fluid is tested and works as follows.The washer 11 is installed prior to Assembly of the cutter between the housing 1 and the valve 4.After Assembly of the cutter and twisting of the housing 1 until it stops is determined by the possibility of movement of the plunger 5 up and down. It is convenient to keep the thickening 10 valve 4. If you move there, then the Assembly is carried out correctly.If the flow of operating fluid to the cutter skips at low (or very high) pressure, then increase (or decrease) the pressure of the spring 7 is more of the gland bolt 8, increasing the pressure of the spring 7 to a value that is not avoidable when the working fluid pressure.Depending on the operating pressure (high, medium, low) is used nozzle 2 nozzle with various in excess of its height above the inner pipe 3.Depending on the ratio of elevation change efforts on the cutoff, as this force is determined, including the transformation of the shape of the valve when the cutoff.When the flat cutoff valve 4 is converted to spherical, which requires less effort in comparison with other options.Use the web clipper fluid ensures a reliable cut-off of the working fluid allows you to adjust the pressure of the working fluid provides reliable cut-off of the working fluid allows you to adjust the supply pressure of the working fluid and thereby complied with the specified dose of entering.In suspension spray by screwing the gland bolt saves maintenance time. In addition, the safe operation of the selectors saves the working fluid and expensive chemicals at a turning lanes at pump shutdown. At the same time decrease the unnecessary emission of chemicals, reduced brewzer fluid supply, the inner axial tube drainage, longitudinally mounted in the nozzle to form with it the annular channel of the fluid, diaphragm valve for blocking the inlet pipe drain, spring-loaded plunger with a stem for moving the valve means to force changes the preload of the spring, wherein the latter is in the form of a spring-loaded bolt with a through axial channel therein for accommodating the stem of the plunger.2.
