Abstract
The utility model proposes a kind of ball seat component of ball valve, including：Ball seat mounting base, the upper end of the mounting hole of the ball seat mounting base have first step and the second step above the first step, and the internal diameter of the first step is less than the second step；Ball seat, the ball seat coordinate in the first step；Sealing ring, the sealing ring are socketed on the outer peripheral edge of the ball seat and coordinate in the second step.The ball seat component of ball valve according to the present utility model, makes ball seat non-deformability stronger, so as to reach sealing effect.
Description
Technical field
It the utility model is related to a kind of ball seat component of ball valve.
Background technology
Pneumatic diaphragm pump suction deficiency, the reason for energy loss is big have it is many-sided, except the pressure shadow of compressed air
Ring outer, equally influenced by diaphragm size and pump shaft movement travel etc., wherein the relation of influence the biggest factor is ball valve, ball socket structure and
Assemble uniformity.
In the diaphragm pump course of work, influenced by pump shaft propulsion, high pressure is formed between diaphragm and column, at this time feed end ball valve
It is stressed and is bonded with ball seat, composition closing valve.Discharge end ball valve is stressed promotion movement upwards, moves to supported after peak
Pawl is constrained and stopped, and material is flowed out by bypassing ball valve after ball seat mounting hole from support claw gap.
As shown in Figure 1, existing ball seat mounting base 100 ' is column type, ball seat 200 ' is projective table type, ball seat sealing ring
300 ' are linked at the step of ball seat 200 ', instantaneous flexural deformation after ball seat 200 ' is hit by high pressure and ball valve, ball seat sealing ring
300 ' deform together in company with ball seat, cause ball valve sealing not tight, so as to reduce suction.
Utility model content
The utility model is intended to solve at least some of the technical problems in related technologies.
For this reason, a purpose of the utility model is to propose that one kind makes ball seat non-deformability stronger, so as to reach close
Seal the ball seat component of the ball valve of effect.
A kind of ball seat component of ball valve according to the present utility model, including：
Ball seat mounting base, the upper end of the mounting hole of the ball seat mounting base have first step and positioned at the first step
Second step above, the internal diameter of the first step are less than the second step；
Ball seat, the ball seat coordinate in the first step；
Sealing ring, the sealing ring are socketed on the outer peripheral edge of the ball seat and coordinate in the second step.
Advantageously, the ball seat is cylinder ring ball seat.
Advantageously, the upper surface of the ball seat mounting base is concordant with the upper surface of the ball seat.
Advantageously, the upper surface of the sealing ring is higher than the upper surface of the ball seat.
The additional aspect and advantage of the utility model will be set forth in part in the description, partly by from following description
In become obvious, or recognized by the practice of the utility model.
Brief description of the drawings
Fig. 1 is the schematic diagram of the ball seat component of existing ball valve；
Fig. 2 is the schematic diagram according to the ball seat component of the ball valve of the utility model one embodiment.
Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
Below with reference to the accompanying drawings it is described in detail the ball seat component of ball valve according to the present utility model.
As shown in Fig. 2, a kind of ball seat component of ball valve according to the present utility model, including：Ball seat mounting base 100, ball seat
200, sealing ring 300.
Specifically, the upper end of the mounting hole 110 of ball seat mounting base 100 has first step 1101 and positioned at first step
Second step 1102 above 1101, the internal diameter of first step 1101 are less than second step 1102.
Ball seat 200 coordinates in first step 1101.Advantageously, ball seat 200 is cylinder ring ball seat.Further, ball seat
The upper surface of mounting base 100 is concordant with the upper surface of ball seat 200.
Sealing ring 300 is socketed on the outer peripheral edge of ball seat 200 and coordinates in second step 1102.Advantageously, sealing ring
300 upper surface is higher than the upper surface of ball seat 200.
That is, a kind of ball seat component of ball valve according to the present utility model, by the installation site of sealing ring from existing
Be installed on ball seat, be changed to be installed in ball seat mounting base, sealing ring installation position is arranged on rigidity preferably ball seat mounting base
On, and ball socket structure is adjusted, original boss structure is changed to cylindrical structure, makes ball seat non-deformability stronger, so as to reach
Sealing effect.
