Abstract
The utility model provides a containment personnel gate pressure balance pipe, includes valve body, spheroid, valve rod and disk seat, is provided with the valve pocket in the valve body, installs rubber seal on the disk seat, spheroid and rubber seal looks adaptation, and the spheroid is installed between disk seat and spheroid open support ring through supporting open support ring, and its spacing step and valve inner surface of the cover looks butt radial and the spheroid surface set up unsteady clearance between its axial and the spheroid. The beneficial effects of the utility model are that: the adoption is supported the spheroid open support ring form, has cancelled the lower valve shaft structure, has reduced installation space, and convenient more, firm to the support of ball valve, to setting up unsteady clearance between open support ring and the spheroid, can guarantee that the spheroid has certain space of freely floating, the accessible pretightning force realizes reliable sealedly with medium power.
Description
Art
The utility model is related to valve technology field, more particularly to a kind of equilibrated valve.
Background technology
Traditional equilibrated valve, its spheroid is supported by upper lower valve rod, has that torque is big, safety coefficient is low, a peace
The big problem in dress space.
The content of the invention
In order to overcome the disadvantages mentioned above of existing equilibrated valve, the utility model to provide a kind of simple structure, installing space
It is little, and the high containment access lock equilibrated valve of safety coefficient.
The utility model solves the technical scheme that its technical problem adopted, a kind of containment access lock pressure balance
Valve, including valve body, spheroid, valve rod and valve seat, are provided with valve pocket in valve body, valve seat, sphere installation are pacified in valve pocket on valve seat
Equipped with elastic seal ring, spheroid forms sealing pair with elastic seal ring, and spheroid is supported by opposite opened support ring, and opposite opened is supported
Ring is arranged between valve seat and spheroid, and it radially connects with the limited step and valve gap contacted inner surfaces of outer surface of spheroid, its axle
To arranging flying height between spheroid.
The beneficial effects of the utility model are：Support loop type to be supported spheroid using opposite opened, eliminate lower valve
Axle construction, reduces installing space, and convenient, firm to the support of ball valve；Arrange between opposite opened support ring and spheroid
Flying height, it is ensured that spheroid has certain free floating space, can realize reliably sealing by pretightning force and medium power.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of embodiment.
In figure：1. valve body；2. elastic seal ring；3. spheroid；4. valve rod；5. valve seat；6. valve gap；7. opposite opened support ring；
8. flying height；9. valve pocket；10. limited step.
Specific embodiment
As shown in figure 1, a kind of containment access lock equilibrated valve, including valve body 1, spheroid 3, valve rod 4 and valve seat
5, valve pocket 9 is provided with valve body 1, valve seat 5, spheroid 3 are arranged in valve pocket 9, and elastic seal ring 2, spheroid 3 are provided with valve seat 5
Form sealing pair with elastic seal ring 2, spheroid 3 supports by opposite opened support ring 7, opposite opened support ring 7 be arranged on valve seat 5 and
Between spheroid 3, it radially connects with the limited step 10 and valve gap contacted inner surfaces of the outer surface of spheroid 3, its axially with spheroid it
Between arrange flying height 8.
