Abstract
The utility model discloses a kind of elastic valve seat ball valve with compensate function, described left valve barrel and right valve barrel tighten together mutually, flap is positioned at left valve barrel and right valve barrel, the lower end of described valve rod is connected with flap, it also includes left compensating spring, right compensating spring, left valve seat bracing ring, right valve seat bracing ring, left valve seat and right valve seat, corresponding groove is offered respectively inside described left valve barrel and right valve barrel, described left compensating spring and right compensating spring are arranged in the groove inside left valve barrel and right valve barrel respectively, left valve seat bracing ring and right valve seat bracing ring are arranged on left compensating spring in described groove and right compensating spring respectively, the utility model advantage is: the working life effectively extending valve, decrease the number of times changing valve, reduce the cost of production of enterprise, also effectively ensure that the normal smoothly of enterprise is produced.
Description
Technical field
The utility model relates to the technical field of valve, more particularly relates to the technical field of ball valve.
Background technique
Valve is the device being used for controlling the direction of fluid, pressure and flow in fluid system, it mainly includes gate valve, stop valve, safety check, membrane valve, stopcock, dish valve, plunger valve and ball valve etc., the sealability of valve refers to that each sealed department steric hindrance of valve stops the ability of dielectric leakage, and it is the most important technical performance index of valve.There are three places at the sealing position of valve: one is the contacting point between open-shut device and valve seat two sealing surface; Two is cooperation places of filler and valve rod and stuffing box; Three is joints of valve body and valve gap.Wherein the leakage at the first place is called interior leakage, namely usually saidly fits badly, and it blocks the ability of medium by affecting valve, for block valve class, interior leakage is unallowed.Current normally used its valve seat of various valve is all the parts in valve body, after using over a long time, contacting point between flap and valve seat just there will be the situation of wearing and tearing, produce to reveal and affect its sealability, usually cannot repair, the valve that can only more renew, so not only can affect the working life of valve, increase the expense cost of enterprise, but also the normal production of enterprise can be affected.
Model utility content
The purpose of this utility model is exactly provide one effectively can extend valve working life to solve above-mentioned deficiency, reduces enterprise's cost of production, the elastic valve seat ball valve with compensate function that guarantee enterprise normally produces smoothly.
The technical solution that the utility model adopts to solve the problems of the technologies described above is as follows:
There is the elastic valve seat ball valve of compensate function, it mainly includes left valve barrel, right valve barrel, flap and valve rod, described left valve barrel and right valve barrel tighten together mutually, flap is positioned at left valve barrel and right valve barrel, the lower end of described valve rod is connected with flap, it also includes left compensating spring, right compensating spring, left valve seat bracing ring, right valve seat bracing ring, left valve seat and right valve seat, corresponding groove is offered respectively inside described left valve barrel and right valve barrel, described left compensating spring and right compensating spring are arranged in the groove inside left valve barrel and right valve barrel respectively, left valve seat bracing ring and right valve seat bracing ring are arranged on left compensating spring in described groove and right compensating spring respectively, left valve seat and right valve seat are arranged on left valve seat bracing ring in described groove and right valve seat bracing ring respectively, flap contacts with left valve seat and right valve seat.
The cross section of described left valve seat bracing ring and right valve seat bracing ring is respectively in step-like.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: by independently being made by valve seat, and being arranged on by valve seat has on the supporting base of automatic compensation function, so just effectively extend the working life of valve, decrease the number of times changing valve, reduce the cost of production of enterprise, also effectively ensure that the normal smoothly of enterprise is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, there is the elastic valve seat ball valve of compensate function, it mainly includes left valve barrel 1, right valve barrel 2, flap 3, valve rod 4, left compensating spring 5, right compensating spring 6, left valve seat bracing ring 7, right valve seat bracing ring 8, left valve seat 9 and right valve seat 10, described left valve barrel 1 and right valve barrel 2 tighten together mutually, flap 3 is positioned at left valve barrel 1 and right valve barrel 2, the lower end of described valve rod 4 is connected with flap 3 and controls the rotation of flap 3, corresponding groove 11 is offered respectively inside described left valve barrel 1 and right valve barrel 2, described left compensating spring 5 and right compensating spring 6 are arranged in the groove 11 inside left valve barrel 1 and right valve barrel 2 respectively, left valve seat bracing ring 7 and right valve seat bracing ring 8 are arranged on left compensating spring 5 in described groove 11 and right compensating spring 6 respectively, left valve seat 9 and right valve seat 10 are arranged on left valve seat bracing ring 7 in described groove 11 and right valve seat bracing ring 8 respectively, the conveniently location of left valve seat 9 and right valve seat 10, the cross section of left valve seat bracing ring 7 and right valve seat bracing ring 8 is designed in step-like respectively, flap 3 contacts with left valve seat 9 and right valve seat 10.Like this, the surface of contact of flap 3 and left valve seat 9 and right valve seat 10 can also extend its working life by effective compensation after being worn.
