Abstract

The invention discloses a switching device in a cone valve, and the switching device is simple to operate. The switching device comprises an end cover and a handle, wherein the end cover is fixedly connected with the top end of a valve body in the cone valve; the handle is articulated with the end part of the top of a valve plug in the cone valve; a side part of one end of the handle which is articulated with the valve plug is provided with a protrusion; and a spring is arranged between the end cover and the valve plug. The switching device provided by the invention has the beneficial effects that the switching among different functions of the cone valve can be realized just through pressing down the handle, rotating the handle and lifting the handle up, therefore, the switching device is very simple to operate.

Description

COMM communication in the cone valve

Technical field

The present invention relates to the COMM communication in a kind of cone valve.

Background technique

Cone valve uses on numerous conveyance conduits extensively, controls the flow direction of fluid in the conveyance conduit or dams through spool and valve body formation relative position in the rotation cone valve.COMM communication is used for the relative position between regulating spool and the valve body.Like Fig. 1, shown in Figure 2; This COMM communication generally includes the end cap 2 that is fixedly connected with valve body 1 top, be set in the regulating handle 10 of spool 3 top ends and be fixedly installed on the spacing handle 11 of spool 3 top ends; Between regulating handle 10 and the end cap 2 through being threaded; End cap 2 outer surfaces are provided with some positioning holes 12, and the position of each positioning hole is corresponding with each POF of cone valve.One locating stud 13 passes spacing handle 11 and inserts in the corresponding positioning hole 12 on the end cap 2.The working principle of above-mentioned COMM communication is: when needs change spool 3 and realize function corresponding with the relative position between the valve body 1, earlier with extracting the positioning hole 12 of locating stud 13 from end cap 2, rotate up regulating handle 10 then and with upwards lifting of spool 3; After spool 3 and valve body 1 break away from, rotary stopper handle 11, spacing handle 11 drives spool 3 and goes to desired location; Be rotated down regulating handle 10 then; Spool 3 descends thereupon, after the internal surface of the outer conical surface of spool 3 and valve body 1 fits fully, locating stud 13 is inserted on the end caps 2 in the positioning hole corresponding 12; Make the relative position between spool 3 and the valve body 1 fix; Be that spool 3 can't rotate in valve body 1, thereby realize the switching of relative position between spool 3 and the valve body 1, cone valve is switched between multiple function.This COMM communication when the relative position that changes between spool 3 and the valve body 1, complex operation.

Summary of the invention

Technical problem to be solved by this invention is: the COMM communication in a kind of cone valve simple to operate is provided.

For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: the COMM communication in a kind of cone valve; Comprise with cone valve in the end cap that is fixedly connected of valve body top; Also comprise with cone valve in the hinged handle of spool top end, hinged one distolateral of handle and spool is provided with convexity, is provided with spring between end cap and the spool.

Be provided with pressing plate between said end cap and the handle, be provided with clutch shaft bearing between pressing plate and the end cap;

Be provided with second thrust-bearing between said end cap and the spring.

The invention has the beneficial effects as follows: only need depress handle, rotatable handle, lift handle and just can realize the switching between the cone valve difference in functionality, operation very simply.

Embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.

As shown in Figure 3; COMM communication in the cone valve of the present invention; Comprise with cone valve in the end cap 2 that is fixedly connected of valve body 1 top and with cone valve in the hinged handle 4 of spool 3 top ends; It is protruding 5 that hinged one distolateral of handle 4 and spool 3 is provided with, and this convexity 5 can contact with end cap 2 after handle 4 is depressed, and make spool 3 lifting that under the effect of handle 4, makes progress.Be provided with spring 6 between end cap 2 and the spool 3, for fear of when spool 3 rotation, between spring 6 and the end cap 2, generation is worn and torn between spring 6 and the spool 3, can between spring 6 and end cap 2, second thrust-bearing be set.In order to reduce handle 4 raisings 5 degree of wear in the process of rotation, between end cap 2 and handle 4, pressing plate 7 is set, first thrust-bearing 8 is set between pressing plate 7 and the end cap 2.Because after between end cap 2 and the handle 4 pressing plate 7 being set, the convexity 5 on the handle 4 is depressed the back at handle 4 and has just been contacted with pressing plate 7, and handle 4 drives pressing plate 7 and rotate together in rotating process, has reduced the wearing and tearing of convexity 5.

Working principle of the present invention is: when cone valve needs switching function, handle 4 is depressed, and the convexity on the handle 45 contacts with pressing plate 7; Spool 3 will be under the effect of handle 4 (lever principle) and overcome under the effect of spring 6 and upwards lift; Make between outer conical surface and the valve body of spool 3 and produce certain interval, be convenient to spool 3 and rotate, handle with sleeve 4 then; Handle 4 drives spool 3 rotations simultaneously; After spool 3 turned to desired location, as long as handle 4 is lifted along articulating point, spool 3 pressed to the outer conical surface of spool 3 and the internal surface applying of valve body 1 under the effect of spring 6.The function switching of cone valve has just been accomplished, and above-mentioned handoff procedure fast, simply.

Claims
