Abstract
The utility model discloses a high temperature ball valve seat seal structure that floats, including disk seat padding pressing ring, valve body, disk seat and spheroid, include still that first disk seat packs, the second disk seat packs and belleville spring, disk seat right part internal surface and spheroid contact, disk seat right part outer wall is the step, and the disk seat left part is cylindric, forms a conical surface between disk seat left part surface and the disk seat right part surface, the conical surface is crescent from a left side to right external diameter, the utility model discloses the mode that provides of replacement disk seat pretightning force, with belleville spring structure replacement spring structure, this structure assembly is simple, and convenient operation can realize the dust sealing of disk seat department, has avoided stopping up the circumstances that makes the valve seat seal performance degradation because of the dust results in the spring, has improved the sealing performance of valve.
Description
Technical field
This utility model is related to machinery valve technology, more particularly, to a kind of high temperature float ball valve base sealing structure.
Background technology
Existing valve seat construction, mainly includes valve body, valve seat, spheroid, spring base, valve seat filler, spring etc., and spring is installed
In the faying face of spring base and valve seat, existing structure dust-proof effect is poor, particularly when lumen medium enters spring hole site
When, spring hole plug is so that spring cannot be desirable to provide pretightning force, thus affecting the sealing property of valve.
Utility model content
This utility model aims to provide a kind of high temperature float ball valve base sealing structure, prevents spring at valve seat to be subject to when suppressing
The sealing property of valve seat is affected when the impact of dust is damaged.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of high temperature float ball valve base sealing structure, including valve seat packing press ring, valve body, valve seat and spheroid, also includes
One valve seat filler, the second valve seat filler and disk spring；Described valve seat right part inner surface is contacted with spheroid；Outside described valve seat right part
Wall is step, and valve seat left part is cylindric, forms a conical surface between valve seat left part outer surface and valve seat outside surface thereof, described
External diameter is gradually increased the conical surface from left to right；Described valve body right part inner surface is fitted with valve seat outside surface thereof；Described valve body and valve
Form a cavity, described cavity sets gradually the first valve seat filler, the second valve seat filler, valve seat filler from right to left between seat
Pressure ring and disk spring；Described disk spring left end and valve body contact, disk spring right-hand member is contacted with valve seat packing press ring.
Preferably, the cross sectional shape of described first valve seat filler is del.
Preferably, the cross sectional shape of described second valve seat filler is right-angled trapezium.
Preferably, external diameter linearly increases the described conical surface from left to right.
Preferably, fitted with the conical surface in the right surface of described first valve seat filler.
Preferably, fitted with the left surface of the first valve seat in the right surface of described second valve seat filler, and described second valve seat is filled out
The cross sectional shape of material right part is the hypotenuse of right-angled trapezium.
Preferably, the right-hand member external diameter of described disk spring is more than left end external diameter.
This utility model is mainly made up of valve body, disk spring, valve seat packing press ring, valve seat filler, valve seat, spheroid etc.,
Compared with original technology, the spring between valve body and valve seat and spring base are substituted for disk spring, when dust is through valve seat,
Not interfering with disk spring provides pretightning force, reduces the risk of valve base sealing inefficacy, improves the service life of valve.This reality
With the presentation mode of new replacement valve seat pretightning force, replace spring structure with disk-shape spring structure, this Standard is simple, operation
Convenient, the dust seal at achievable valve seat, it is to avoid because dust leads to the spring blocking to make the situation that valve base seal property reduces,
Improve the sealing property of valve.
