Abstract
The present invention relates to a kind of lower resistance Anti-seismic ball valve and its manufacture method, the ball valve body and column spinner, housing, the switching device matched with housing include the connecting support structure of valve ball and connection and fixed valve ball and column spinner；The ball valve body is matched by sealing structure with valve ball；Radially aspect inlays multiple equalitys to the ball surface and inner homogeneous is integrated with the polyflon of graphite powder.The lower resistance Anti-seismic ball valve of the present invention can self-lubricating reduce abrasion and strenuous vibration when can bear long.
Description
Technical field
The present invention relates to control wetting system field, more particularly to a kind of lower resistance Anti-seismic ball valve and its manufacture method.
Background technology
Ball valve is opening and closing element（Spheroid）Driven by valve rod, and the valve rotated around ball valve axis.Available for fluid
Regulation and control, wherein firmly sealing its V-type core of V-type ball valve and pile-up welding hard alloy metal seat valve between have it is very strong
Shearing force, is particularly suitable for use in the medium of fibre-bearing, small solid material etc..And multi-pass ball valve not only can be controlled flexibly on pipeline
Interflow, shunting and the switching of flow direction of medium, while any passage also can be closed and two other passage is connected.This class valve
Door should be typically horizontally mounted in the duct.Ball valve is divided into according to type of drive：Pneumatic ball valve, electrical ball valve, manual ball valve.
But it is not applied to large-scale water control equipment long term frequent in the prior art to switch and shake violent operating mode, therefore urgently
Whne it is a kind of can self-lubricating reduce abrasion and when can bear long strenuous vibration ball valve.
The content of the invention
For solve prior art present in drawbacks described above, the present invention is intended to provide one kind can self-lubricating reduce abrasion and can
The lower resistance Anti-seismic ball valve and its manufacture method of strenuous vibration during bearing long.
In order to realize foregoing invention purpose, the present invention uses following technical scheme：A kind of lower resistance Anti-seismic ball valve, including
Ball valve body and column spinner, housing, the switching device matched with housing, in addition to valve ball and connection and fixed valve ball and column spinner
Connecting support structure；The ball valve body is matched by sealing structure with valve ball；The ball surface radially inlay by aspect
Multiple equalitys and inner homogeneous are integrated with the polyflon of graphite powder.
A kind of method for manufacturing above-mentioned valve ball, comprises the following steps：
1. spherical blank is processed using mechanical system；
2. S-shaped groove, ditch groove depth 5mm-8mm, wide 8mm-10mm are equidistantly processed at same direction in spherical blank surface；
3. the main shaft parallel direction constructed jointly by S-shaped groove, which is erected, cuts out two coequal plane of flows excessively, obtains valve ball
Matrix；
4. polyflon raw material is heated to 350 DEG C -360 DEG C, as fluid state, adds graphite powder, insulation is taken out true
Sky simultaneously stirs, and obtains fluid-mixing；
5. in the fluid-mixing that 4. the valve ball matrix immersion step 3. step obtained obtains, rotate and stir 10min-15min,
Cooling is taken out, valve ball blank is obtained；
6. the plastic hybrid of excess surface is removed using the processing of oilstone ball milling, then using mechanical system finishing and polishes valve ball
Blank surface, that is, valve ball needed for obtaining.
Compared with prior art, the present invention has advantages below：In routine techniques frequently with stainless steel, cast iron, plastics,
Brass, zinc alloy material etc., are not strengthened and are modified, main to carry out function guarantor by the way of accessory is changed in continuous maintenance
Hold, but deriving and develop with the epoch, this high-frequency of original technology is safeguarded and the shortcoming of basic property can no longer expire
The existing Medium or severe type of the foot industrial long-life for saving control water field to ball valve, high reliability request；The ditch of S-shaped is used in ball surface
Groove is used to fill the polytetrafluoroethylene (PTFE) for being mixed with graphite powder, is on the one hand due to that graphite powder and polytetrafluoroethylene (PTFE) are all lubricity pole
Good material, can provide lubrication when ball valve is rotated, hence it is evident that reduction rotary resistance, simultaneously because polytetrafluoroethylene (PTFE) material is partially soft,
Also there are special " cold flow properties ", a large amount of shock energies can be absorbed in strenuous vibration and enough bufferings are provided, are made in vibrations
Most easily damaged valve ball shock resistance is greatly enhanced.
