Abstract
A kind of containment access lock equilibrated valve, including valve body, sphere, valve rod and valve seat, valve chamber is provided in valve body, rubber seal is installed on valve seat, sphere is adapted with rubber seal, and sphere is supported by opposite opened support ring, and opposite opened support ring is mounted between valve seat and sphere, its radial limited step and valve deck contacted inner surfaces with outer surface of spheroid connects, and flying height is arranged between axial direction and sphere.The beneficial effects of the present invention are: being supported using opposite opened support loop type to sphere, lower valve axle construction is eliminated, reduces installation space, and more convenient, firm to the support of ball valve；Flying height is set between opposite opened support ring and sphere, it is ensured that sphere has certain free floating space, can realize reliable sealing by pretightning force and medium power.
Description
Technical field
The present invention relates to valve technology field, in particular to a kind of equilibrated valve.
Background technique
Traditional equilibrated valve, sphere are supported by upper lower valve rod, and that there are torques is big, safety coefficient is low, peace
Fill the big problem in space.
Summary of the invention
In order to overcome the disadvantages mentioned above of existing equilibrated valve, the present invention provides that a kind of structure is simple, installation space is small, and
The high containment access lock equilibrated valve of safety coefficient.
The technical solution adopted by the present invention to solve the technical problems is a kind of containment access lock equilibrated valve,
Including valve body, sphere, valve rod and valve seat, valve chamber is provided in valve body, valve seat, sphere installation are installed on valve seat in valve chamber
Flexible sealing ring, sphere and elastic seal ring form sealing pair, and sphere is supported by opposite opened support ring, opposite opened support ring
It is mounted between valve seat and sphere, radial limited step and valve deck contacted inner surfaces with outer surface of spheroid connects, axial direction
Flying height is set between sphere.
The beneficial effects of the present invention are: being supported using opposite opened support loop type to sphere, lower valve shaft knot is eliminated
Structure reduces installation space, and more convenient, firm to the support of ball valve；It is arranged between opposite opened support ring and sphere and floats
Gap, it is ensured that sphere has certain free floating space, can realize reliable sealing by pretightning force and medium power.
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of embodiment.
In figure: 1. valve bodies；2. elastic seal ring；3. sphere；4. valve rod；5. valve seat；6. valve deck；7. opposite opened support ring；
8. flying height；9. valve chamber；10. limited step.
Specific embodiment
As shown in Figure 1, a kind of containment access lock equilibrated valve, including valve body 1, sphere 3, valve rod 4 and valve seat
5, valve chamber 9 is provided in valve body 1, and valve seat 5, sphere 3 are mounted in valve chamber 9, and elastic seal ring 2, sphere 3 are equipped on valve seat 5
With elastic seal ring 2 formed sealing pair, sphere 3 by opposite opened support ring 7 support, opposite opened support ring 7 be mounted on valve seat 5 and
Between sphere 3, radial limited step 10 and valve deck contacted inner surfaces with 3 outer surface of sphere is connect, axial and sphere it
Between be arranged flying height 8.
