Abstract
The invention discloses the ball valve of a kind of good leak tightness, including valve body, valve rod, spheroid and sealing ring, described sealing ring is two, left and right, sealing ring is bonded on the valve seat of valve body, described sealing ring includes cushion and sealant, described cushion side is bonding with valve seat, and cushion opposite side is bonding with sealant.This ball valve has the highest seal, and especially after ball valve uses for a long time, its reliability sealed is the highest, it is possible to be prevented effectively from the fluid leakage owing to sealing ring is hardening or deformation causes.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to the ball valve of a kind of good leak tightness.
Background technology
Ball valve is that a class opening and closing element is driven by valve rod, and the valve rotated around ball valve axis, also can be used for fluid
Regulation and control.The ball valve being currently known mainly includes valve body, valve rod, spheroid and sealing ring, tight by spheroid and sealing ring
Contiguity touches the sealing realizing ball valve, and spinning ball is to realize the opening and closing of valve.Ball valve sealing loop material mainly uses poly-at present
Tetrafluoroethene, politef has the higher coefficient of expansion, sensitivity and the bad heat conductivity to cold flow, therefore, when
When encapsulant is hardening or deforms, the reliability of ball valve sealing is just destroyed.
Summary of the invention
In order to solve the problems referred to above, the present invention provides the ball valve of a kind of good leak tightness, and this ball valve has the highest seal,
Especially after ball valve uses for a long time, its reliability sealed is the highest, it is possible to be prevented effectively from owing to sealing ring is hardening or deformation
The fluid leakage caused.
The present invention is achieved through the following technical solutions:
The ball valve of a kind of good leak tightness, including valve body, valve rod, spheroid and sealing ring, described sealing ring is two, left and right, sealing ring
Being bonded on the valve seat of valve body, described sealing ring includes cushion and sealant, and described cushion side is bonding with valve seat, buffering
Layer opposite side is bonding with sealant.
Described cushion is made up of gum elastic, is provided with cushion chamber inside gum elastic, is filled with bouncing ball in cushion chamber.
Bouncing ball is arranged in cushion chamber, it is to avoid with extraneous contact, prevent bouncing ball aging during life-time service, damage, prolong
The service life of long cushion.
Described bouncing ball is made up of butadiene rubber, bouncing ball a diameter of 0.05～2.0mm.Can be according to the ball valve of different size
The diameter of regulation bouncing ball.
The sealant of described sealing ring is made up of hydrogenated nitrile-butadiene rubber.
The present invention compared with prior art, has such advantages as and beneficial effect:
The ball valve of a kind of good leak tightness of the present invention, by adhering to one layer of cushion at the sealant of sealing ring and valve base chamber, effectively
Improve the sealing effectiveness of ball valve, when ball valve uses the time longer, the elastic force after sealant deforms or be hardening, in cushion
Ball still can make the sealant of sealing ring be close to the spheroid after closing, and promotes ball valve sealing effect, extends ball valve service life.

Embodiment
As shown in Figures 1 to 3, the ball valve of a kind of good leak tightness, including valve body 1, valve rod 2, spheroid 3 and sealing ring 4, described close
Seal 4 is two, left and right, and sealing ring 4 is bonded on the valve seat 5 of valve body 1, and described sealing ring 4 includes cushion 41 and sealant
42, described cushion 41 side is bonding with valve seat 5, and cushion 41 opposite side is bonding with sealant 42.
Described cushion 41 is made up of gum elastic, is provided with cushion chamber 43, is filled with in cushion chamber 43 inside gum elastic
Bouncing ball 44.
Described bouncing ball 44 is made up of butadiene rubber, bouncing ball 44 a diameter of 0.05～2.0mm.
The sealant 42 of described sealing ring 4 is made up of hydrogenated nitrile-butadiene rubber.
Ball valve of the present invention is applied to fluid transmission, and the sealant 42 of sealing ring 4 contacts with spheroid 3, it is achieved valve close
Envelope, when sealant 42 contacts with spheroid 3, cushion 41 is compressed to maximum, when sealant 42 uses the time longer and hardening or becomes
During shape, due to the existence of cushion 41, the bouncing ball 44 in cushion chamber 43 can adjust according to the deformation extent of sealant 42
Self-deformation amount, makes up the space being likely to occur owing to sealant 42 is hardening or deforms, it is ensured that sealant 42 is with spheroid 3 still
Can seamless connection, promote sealing property of ball valves, extend ball valve service life.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all should comprise
Within protection scope of the present invention.
