Abstract
The utility model discloses a kind of anti-wear spool travel leveling style ball valve, comprise valve body (1), valve rod (2) and spool (3), the cavity volume (101) for accommodating spool (3) is provided with in valve body (1), spool (3) is arranged in cavity volume (101), valve rod (2) is fixedly connected with spool (3) through valve body (1), spool (3) is provided with groove (5) with the wall contacting point, chamber of cavity volume (101), the chamber wall of cavity volume (101) is provided with convex surface (6), when spool (3) rotates, convex surface (6) is mobile along groove (5).A kind of anti-wear spool travel leveling style ball valve of the utility model, groove limits convex surface and produces displacement along grooved tracks, and spool travel is steady, and spool face does not directly contact with the chamber wall of cavity volume, prevents spool from wearing and tearing.
Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of anti-wear spool travel leveling style ball valve.
Background technique
In fluid-transporting tubing, it is large that ball valve has the amount of opening, and opens and closes fast advantage and be widely used, ball valve it there is the action of 90-degree rotation, faucet body (spool) is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline, only needs to use the operation of 90-degree rotation and very little moment of rotation just can close tight.In use, owing to frequently rotating spool, the contact position of spool and valve body easily weares and teares ball valve, double swerve when causing valve core rotation, produces vibration, produces liquid or gas internal leakage simultaneously.
In prior art, CN203239985 discloses a kind of Vacuum ball valve, solves because sealing seat wearing and tearing cause technical problems such as letting out in medium generation; The cavity volume inwall of described valve body is provided with U shape groove, in this U shape groove, is provided with the elastic seal ring being formed and seal that to fit with spool sphere.This patent makes up by the elasticity of seal ring the gap that the wearing and tearing because of seal ring produce, thus effectively prevent vacuum valve occurs because sealing seat wearing and tearing in let out, the working life of guarantee valve.But this patent does not solve the problem of anti-spool and valve body wearing and tearing, only to have carried out after generation wearing and tearing anti-in let out process.
Further, in prior art, when ball valve closes, due to the unexpected change of valve pressure at both sides and the time delays of pass valve, easily produce backwater, in order to anti-non-return water, usually need that safety check is installed and coordinate ball valve to use, increase cost, installation and maintenance trouble.
Model utility content
In order to solve prior art problem, the utility model provides a kind of anti-wear spool travel leveling style ball valve, and can prevent spool and valve body wearing and tearing, spool travel is steady, not double swerve, extends ball valve working life.
The technical solution adopted in the utility model is:
A kind of anti-wear spool travel leveling style ball valve, comprise valve body, valve rod and spool, the cavity volume for accommodating spool is provided with in valve body, spool is arranged in cavity volume, valve rod is fixedly connected with spool through valve body, and the wall contacting point, chamber of spool and cavity volume is provided with groove, and the chamber wall of cavity volume is provided with convex surface, during valve core rotation, convex surface moves along groove.Pull valve rod, spool rotates with valve rod, and convex surface moves in groove relative to spool, groove limits convex surface and produces displacement along grooved tracks, can not left and right displacement, and spool travel is steady, meanwhile, spool face does not directly contact with the chamber wall of cavity volume, prevents spool from wearing and tearing.
Spool includes the mouth of a river and water outlet, is provided with spiral pipe between water inlet and water outlet.Backwater can be buffered in pipeline by spiral pipe, prevents liquid backflow.
Sealing gasket is provided with in groove.Sealing gasket is silicone rubber seal gasket.Silicone rubber seal gasket is wear-resistant, and corrosion-resistant.
Convex surface is ceramic material, and ceramic material is wear-resistant and corrosion-resistant.
Convex surface is arc-shaped, arc-shaped convex surface and cavity volume surface of contact little, reduce the friction of convex surface and cavity volume.
The internal diameter of spiral pipe is equal to, or greater than the internal diameter of water inlet.Spiral pipe is made to have enough capacity to accommodate withdrawing fluid.
Compared with prior art, the utility model beneficial effect comprises:
A kind of anti-wear spool travel leveling style ball valve of the utility model, groove limits convex surface and produces displacement along grooved tracks, and spool travel is steady, and spool face does not directly contact with the chamber wall of cavity volume, prevents spool from wearing and tearing;
Further, spiral pipe is provided with between the water inlet of spool and water outlet.Backwater can be buffered in pipeline by spiral pipe, prevents liquid backflow.
