Abstract

A kind of containment access lock equilibrated valve, including valve body, spheroid, valve rod and valve seat, valve pocket it is provided with in valve body, rubber seal is installed on valve seat, spheroid is suitable with rubber seal, and spheroid is supported by opposite opened support ring, and opposite opened support ring is arranged between valve seat and spheroid, its radial direction connects with limited step and the valve gap contacted inner surfaces of outer surface of spheroid, and it axially and arranges flying height between spheroid.The invention has the beneficial effects as follows: use opposite opened support ring form that spheroid is supported, eliminate lower valve shaft structure, reduce installing space, and the support to ball valve is convenient, firm；Between opposite opened support ring and spheroid, flying height is set, it is ensured that spheroid has certain free floating space, can realize reliably sealing by pretightning force and medium power.

Description

A kind of containment access lock equilibrated valve
Art
The present invention relates to valve technology field, particularly to a kind of equilibrated valve.
Background technology
Traditional equilibrated valve, its spheroid is supported by upper lower valve rod, has that moment is big, safety coefficient is low, a peace The problem that dress space is big.
Summary of the invention
In order to overcome the disadvantages mentioned above of existing equilibrated valve, the present invention provides a kind of simple in construction, installing space little, and The containment access lock equilibrated valve that safety coefficient is high.
The technical solution adopted for the present invention to solve the technical problems is, a kind of containment access lock equilibrated valve, Including valve body, spheroid, valve rod and valve seat, being provided with valve pocket in valve body, valve seat, sphere installation, in valve pocket, valve seat are installed Flexible sealing ring, spheroid forms sealing pair with elastic seal ring, and spheroid is supported by opposite opened support ring, opposite opened support ring Being arranged between valve seat and spheroid, its radial direction connects with limited step and the valve gap contacted inner surfaces of outer surface of spheroid, and it is axial And flying height is set between spheroid.
The invention has the beneficial effects as follows: use opposite opened support ring form that spheroid is supported, eliminate lower valve shaft knot Structure, reduces installing space, and the support to ball valve is convenient, firm；Between opposite opened support ring and spheroid, floating is set Gap, it is ensured that spheroid has certain free floating space, can realize reliably sealing by pretightning force and medium power.
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
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.
Detailed description of the invention
As it is 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, it is provided with valve pocket 9 in valve body 1, valve seat 5, spheroid 3 are arranged in valve pocket 9, and valve seat 5 is provided with elastic seal ring 2, spheroid 3 Forming sealing pair with elastic seal ring 2, spheroid 3 is supported by opposite opened support ring 7, opposite opened support ring 7 be arranged on valve seat 5 with Between spheroid 3, its radially limited step 10 and valve gap contacted inner surfaces with spheroid 3 outer surface connect, its axially and spheroid it Between flying height 8 is set.
