Description
Technical field
The present invention relates to a kind of ball valve, especially a kind of used at ultra-low temperature upper-mounting type ball valve valve seat construction.
Background technique
Common ultralow temperature upper-mounting type ball valve valve seat construction at present, is face and face contact between pre-load nut and spring base,
Very big frictional force can be generated when by pre-tightening rotatable handle pre-load nut, increasing assembly difficulty；Pin shaft, which is inserted directly into, to be prevented turn-taking,
It does not fix, there is the phenomenon that sliding when filling the components such as valve seat fixator；
It when spring base is packed into valve seat fixator, is contacted due to being metal with metal, exists and scratch valve seat fixator surface smoothness
Hidden danger；Valve body inner bore face and sealing ring contact position are due to the limitation of processing technology, and surface smoothness can not be up to standard, Wu Fabao
Demonstrate,prove the installation requirement of sealing ring.
Summary of the invention
For the above problem of the prior art, the present invention provides to be filled on easy to assembly, reliable performance the used at ultra-low temperature of one kind
Formula ball valve base structure.
The technical scheme is that a kind of used at ultra-low temperature upper-mounting type ball valve valve seat construction, including valve seat fixator, it is described
Valve seat fixator is equipped with sealing ring I, and the sealing ring I is abutted with sphere, and pre-load nut on the valve seat fixator is described pre-
Tight nut is abutted with spring base, and the spring base is equipped with spring, and the spring is abutted with valve body, the valve seat fixator and valve
Sealing ring II is equipped between body, the sealing ring II is abutted by spring base with valve body, and the valve seat fixator is equipped with pin groove,
The pin groove is equipped with pin shaft, and the pin shaft is abutted by anti-turn-take with valve body, and the spring base is with pre-load nut bearing surface
Spherical surface, the spring base are equipped with guide groove, and the guide groove is provided with filler, and gear is equipped between the sealing ring II and valve body
Circle, the pin shaft be it is ladder-like, it is described anti-to turn-take equipped with counterbore.
The invention has the advantages that reducing the frictional force generated when pre-load nut rotation, make to assemble more convenient；It keeps away
Exempt from pin shaft and slides scene when filling valve seat fixator；The hidden danger for scratching valve seat fixator surface smoothness is eliminated, is protected
The reliability for demonstrate,proving valve seat fixator surface smoothness, can improve the sealing performance of general plug sealing ring；The installation for meeting general plug is wanted
The sealing performance for making valve is asked further to be promoted.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: 1. spheres；2. sealing ring I；3. valve seat fixator；4. pre-load nut；5. spring base；6. spring；
7. valve body；8. filler；9. sealing ring II；10. retaining ring；11. pin shaft；12. anti-turn-take.
Specific embodiment
As shown in Figure 1, a kind of used at ultra-low temperature upper-mounting type ball valve valve seat construction, including valve seat fixator, the valve seat are fixed
Device is equipped with sealing ring I, and the sealing ring I abuts with sphere, pre-load nut on the valve seat fixator, the pre-load nut and
Spring base abuts, and the spring base is equipped with spring, and the spring is abutted with valve body, is equipped between the valve seat fixator and valve body
Sealing ring II, the sealing ring II are abutted by spring base with valve body, and the valve seat fixator is equipped with pin groove, the pin shaft
Slot is equipped with pin shaft, and the pin shaft is abutted by anti-turn-take with valve body, and the spring base and pre-load nut bearing surface are spherical surface, described
Spring base is equipped with guide groove, and the guide groove is provided with filler, and retaining ring, the pin shaft are equipped between the sealing ring II and valve body
To be ladder-like, anti-turn-take is equipped with counterbore.
