Abstract
A kind of Novel pressure-reducing formula ball valve, including valve body are provided with sphere in valve body, and support base is provided with below sphere, and support base is arranged on valve body, and cushion block is provided between support base and sphere, and cushion block setting is provided with one group of vent on support base, on cushion block.The utility model has the advantages that: playing buffer function by cushion block, sphere is reduced to the pressure of valve seat, reduce the medium active force that sphere is subject to by vent, to realize effect of easing stress, the sealing performance between sphere and valve seat is improved, reduces the damage of sphere and valve seat, improve the service life of ball valve, cost is reduced, using effect is good, is conducive to promote.
Description
Technical field
The utility model relates to ball valve technical field more particularly to a kind of Novel pressure-reducing formula ball valves.
Background technique
Currently, when in use, due to the effect of medium, sphere is acted on just common ball valve by the pressure of medium on the market
Pressure effect can be transferred on valve seat, therefore, the sealing performance being used for a long time between rear valve base and sphere will reduce, and
And sphere and valve seat are easily damaged, and need to be regularly maintained replacement, it is at high cost.
Utility model content
The utility model will solve the above-mentioned problems of the prior art, provide a kind of Novel pressure-reducing formula ball valve, can subtract
Few medium reduces the pressure that valve seat is subject to the active force of sphere, realizes effect of easing stress.
The utility model solves the technical solution of its technical problem use: this Novel pressure-reducing formula ball valve, including valve body, valve
It is provided with sphere in vivo, support base is provided with below sphere, support base is arranged on valve body, is arranged between support base and sphere
There is cushion block, cushion block setting is provided with one group of vent on support base, on cushion block.
Backing plate is provided between cushion block and support base, backing plate is arranged on support base.
One group of spring is provided between cushion block and backing plate.
The utility model has the advantages that: the Novel pressure-reducing formula ball valve of the utility model, structurally reasonable, is risen by cushion block
It to buffer function, reduces sphere to the pressure of valve seat, the medium active force that sphere is subject to is reduced by vent, thus real
Existing effect of easing stress, improves the sealing performance between sphere and valve seat, reduces the damage of sphere and valve seat, and that improves ball valve uses the longevity
Life, reduces cost, and using effect is good, is conducive to promote.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: valve body 1, sphere 2, support base 3, cushion block 4, vent 5, backing plate 6, spring 7.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: this Novel pressure-reducing formula ball valve in the present embodiment, including valve body 1 are provided with sphere 2, ball in valve body 1
The lower section of body 2 is provided with support base 3, and support base 3 is arranged on valve body 1, and cushion block 4 is provided between support base 3 and sphere 2, pads
Block 4 is arranged on support base 3, and one group of vent 5 is provided on cushion block 4.
Backing plate 6 is provided between cushion block 4 and support base 3, backing plate 6 is arranged on support base 3.
One group of spring 7 is provided between cushion block 4 and backing plate 6.
The effect of cushion block 4 is to play buffer function, reduce sphere 2 to the pressure of valve seat, reduces ball by vent 5
The medium active force that body 2 is subject to, to realize effect of easing stress, 7 one side of spring plays effect of easing stress, on the other hand also functions to branch
Effect is supportted, cushion block 4 is made of rubber material.
Also there are the other components such as valve rod on valve body 1, it is identical as conventional ball valve, it repeats no more.
When work, medium generates pressure to sphere 2, and partial pressure is transferred to cushion block 4 by sphere 2, then passes through cushion block 4
Vent 5 is eliminated.
The characteristics of the utility model embodiment, is: buffer function played by cushion block 4, reduces sphere 2 to the pressure of valve seat,
Reduce the medium active force that sphere 2 is subject to by vent 5, to realize effect of easing stress, improves between sphere 2 and valve seat
Sealing performance, reduce sphere 2 and valve seat damage, improve the service life of ball valve, reduce cost, using effect is good, is conducive to
It promotes.
Although the utility model is shown and described by reference to preferred embodiment, this profession is common
Technical staff is it is to be appreciated that within the scope of the claims, can make various variation in form and details.
