The pretightning force of utilizing the ball core to provide is sealed, prevents the medium to enter into the clearance between valve body and the valve seat, plays the guard action.
Description
Technical field
This utility model belongs to universal machine valve technology field, more particularly to a kind of band protection structure for ball valve
Metal seat valve device.
Background technology
Ball valve (ball valve) is to be developed by plug valve (plug valve), and its opening and closing element is as a ball
Body, rotates 90 °, around the axis of valve rod, the purpose realized valve opening and close using spheroid.Ball valve is not only simple in structure, seals
Performance is good, and in the range of certain inside nominal diameter small volume, lightweight, material consumption is few, installation dimension is little, have
Little circulating resistance, ball valve and to have a driving torque little, easy and simple to handle, the advantages of easily realize fast opening and closing, it is the nearly more than ten years
Carry out one of valve kind with fastest developing speed.The sealing means of ball valve have soft seal and hard sealing two ways, and soft seal refers to valve
Seat is that nonmetallic materials are made, such as epdm, the composition such as ptfe, directly using core and valve body to the extruding of metal seat valve Lai
Realize the sealing of valve, hard sealing refers to that metal seat valve is that metal material is made, in order to ensure sealing has to provide pretension
Power makes metal seat valve tightly be attached to the surface of core, has gap between valve body and metal seat valve.In real work, have
Medium be in pressed powder or medium contain solid particle it is easy to enter in this gap, formed pile up, lift gold
Belong to valve seat, make moment of torsion increase, damaging valve stem or the direct locking extremely of valve, valve cannot realize the action opening and closing.This reality
It is exactly that the gap that valve body is formed with metal seat valve is protected by with new purpose, stop medium from entering cavity, formed and pile up.
Content of the invention
The purpose of this utility model is to improve the deficiency of prior art, provides a kind of peace of the ball valve metal seat valve with protection
Assembling structure, under powdery medium or the working environment containing Solid micro, stops medium from entering valve body and metal seat valve
The service life of valve, it is ensured that the safe and stable operation of valve, is improved in the gap being formed.
For realizing this utility model purpose, there is provided technical scheme below: a kind of ball valve metal seat valve with protection structure
Mounting structure, including valve body it is characterised in that valve body center offers metal valve bore, metal seat valve in the hole is provided with metal valve
Seat, metal valve bore and the level connection joint end face of metal seat valve offer the first sealed groove, metal valve bore and metal valve
The contact surface of seat side wall offers the second sealed groove, is provided with sealing ring, metal seat valve horizontal plane in first and second sealed groove
It is provided with wavy spring and between metal seat valve hole horizontal end face, valve body inner spherical core sphere coordinates pretension with metal seat valve.
Preferably, wavy spring forms for rustless steel bending.
For realizing this utility model purpose, there is provided another kind of technical scheme: a kind of ball valve metal valve with protection structure
Seat installation structure, including valve body it is characterised in that valve body center offers metal valve bore, metal seat valve in the hole is provided with gold
Belong to valve seat, the horizontal end face of metal seat valve begins with the first sealed groove, and metal seat valve side wall offers the second sealed groove, the
First, it is provided with sealing ring in two sealed grooves, between metal seat valve horizontal plane and metal seat valve hole horizontal end face, be provided with waveform bullet
Spring, valve body inner spherical core sphere coordinates pretension with metal seat valve.
Preferably, wavy spring forms for rustless steel bending.
Preferably, wavy spring is arranged in the gap between the first and second sealed grooves.In valve body and metal valve
It is equipped with stainless steel material between seat and makes wavy spring, the pretightning force of valve seal is provided.
Be equipped with two seals circle between valve body and metal seat valve, its effect: one be to ensure that metal seat valve and valve body it
Between sealing, valve do not leak, and two is the cavity being formed between protection valve body and metal seat valve, stops medium from entering deposition.
This utility model beneficial effect: it is machined with two seals circle ditch in the metal seat valve hole site of valve body, or in gold
Belong to valve seat processing two seals ring recess, the two seals circle one of assembling is to ensure that the sealing between metal seat valve and valve body, valve
Do not leak, two is the cavity being formed between protection valve body and metal seat valve, stops medium from entering deposition, prevents valve torque
Abnormal increase or the generation of core locking phenomenon.It is equipped with stainless steel material and make waveform bullet between valve body and metal seat valve
Spring, provides the pretightning force of valve seal, allows metal seat valve fit tightly on it is ensured that sealing on the outer surface of core, simultaneously right
Also the possibility that High Pressure Difference brings core displacement can be offset for floating ball valve.
Therefore, this utility model disclosure satisfy that the technical requirements using scene, and production run is safe and reliable, the use of valve
Life-span is greatly improved, and can greatly improve the economical production scale of enterprise, obtains economic benefit.
