Abstract

The utility model discloses a switching device in a conical valve, which is simple to operate. The switching device comprises an end cover fixed connected with the top end of a valve body of the conical valve and a handle hinged with the top end of a valve spool of the conical valve, wherein a bulge is arranged at the end of one side of the handle, on which the handle is hinged with the valve spool, and a spring is arranged between the end cover and the valve spool. The switching device disclosed by the utility model has the following benefit: different functions of the conical valve can be switched by only pressing, rotating and lifting the handle, which is very simple to operate.

Description

COMM communication in the cone valve

Technical field

The utility model 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 by 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.As shown in Figure 1 and Figure 2, this COMM communication generally includes the end cap 2 of fixedlying 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 by 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 position of function 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 the relative position between needs change spool 3 and the valve body 1 is realized function corresponding, to extract the positioning hole 12 of locating stud 13 from end cap 2 earlier, rotate up regulating handle 10 then and spool 3 is upwards promoted, 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, in positioning hole corresponding 12 on the locating stud 13 insertion end caps 2, 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.

The model utility content

Technical problem to be solved in the utility model 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 technical solution adopted in the utility model is: the COMM communication in a kind of cone valve, comprise the end cap of fixedlying connected with valve body top in the cone valve, also comprise with cone valve in the hinged handle of spool top end, the hinged distolateral portion of handle and spool is provided with projection, is provided with spring between end cap and the spool.

Be provided with pressing plate between described 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 described end cap and the spring.

The beneficial effects of the utility model are: only need depress handle, rotatable handle, lift handle and just can realize switching between the cone valve difference in functionality, operate very simple.

Embodiment

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

As shown in Figure 3, COMM communication in the cone valve described in the utility model, comprise the end cap 2 of fixedlying connected with valve body 1 top in the cone valve and with cone valve in the hinged handle 4 of spool 3 top ends, handle 4 and spool 3 hinged distolateral portions are provided with projection 5, this projection 5 can contact with end cap 2 after handle 4 is depressed, and spool 3 is upwards promoted under the effect of handle 4.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 projection 5 degree of wear in the process of rotation on the handle 4, 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 projection 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 by protruding 5 wearing and tearing.

Working principle of the present utility model is: when cone valve needs switching function, handle 4 is depressed, and the projection 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 the outer conical surface of spool 3 and the valve body and produce certain interval, being convenient to spool 3 rotates, handle with sleeve 4 then, handle 4 drives spool 3 rotations simultaneously, after spool 3 turns to desired location, as long as handle 4 is lifted along articulating point, spool 3 presses 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 finished, and above-mentioned handoff procedure fast, simply.
