Description
Technical field
The utility model category valve technology field, and in particular to a kind of that there is the valve bullet for reducing abrasion and providing sealing force
Property touches structure.
Background technology
Nuclear power, petrochemical industry, national standard are defeated in storage and pipeline for severe corrosive, strong radioactive and hypertoxicity medium
Inside and outside slip level requirement during sending is very stringent.But in practical work, due to valve seal problem, it is particularly
Under high-temperature and high-pressure conditions, limited by conditions such as sealing material, sealing structure, radioactivity, sealing force and manufacturing process,
The sealing performance of valve is extremely difficult to national requirements, and particularly under valve-closed state, the deficiency of sealing force directly causes valve
The problem of door sealing slip is high.It is therefore desirable to propose to improve.
Utility model content
The technical problem that the utility model solves：A kind of valve elasticity that there is reduction abrasion and sealing force is provided is provided to touch
Binding structure, enough sealing forces when the utility model can provide low pressure for the sealing structure of spool needed for sealing, is improved
Sealing performance when valve is closed, and the frictional force that spool moves in valve core channel can be reduced, reduce abrasion, extending valve makes
Use the service life.
The technical solution adopted in the utility model：Structure is touched with the valve elasticity for reducing abrasion and offer sealing force,
Including valve body and spool, the valve inner is equipped with valve core channel, and the spool and valve core channel are cylindrical-shaped structure, described
The opening and closing that spool adaptation is installed on inside valve core channel and is realized by moving up and down to valve, the spool side is set
The sealing structure of rigid seal pair can be formed when it moves down into valve core channel lower limit closing valve by having, and the spool opposite side is set
There is the rolling of multigroup and valve core channel cylindrical form interior surface to touch and the elastic parts of sealing force is provided sealing structure, described every group
Elastic parts includes magnetic spring and ball, and side is corresponded on the spool and is equipped with installing blind, it is blind that the magnetic spring is arranged on installation
In hole, the magnetic outer spring end is connected with rolls the ball touched with the valve core channel inner periphery in valve body.
Wherein, the magnetic spring is made of two pieces of identical permanent magnets of adjacent surface polarity.
Further, two pieces of permanent magnets for forming magnetic spring are made of samarium-cobalt permanent-magnetic material.
Further, the elastic parts installation group is several determines and is no less than according to medium character in gate valve and operating pressure
4 groups.
The utility model compared with prior art the advantages of：
1st, this programme is equipped with multigroup elastic parts in spool side, and the magnetic spring in elastic parts is identical by adjacent surface polarity
Two pieces of permanent magnets form, when valve core movement to valve core channel closing valve position when, the effect of magnetic spring mutual expelling force can
For enough sealing forces when providing low pressure for sealing structure needed for sealing of spool opposite side, improve close when valve is closed
Sealing property；
2nd, this programme is equipped with ball in magnetic outer spring end, and ball is rolled with valve core channel inner periphery and touched, so as to
The frictional force that spool moves in valve core channel is enough reduced, reduces abrasion, extends valve service life.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
1 embodiment for describing the utility model below in conjunction with the accompanying drawings.
Structure is touched with the valve elasticity for reducing abrasion and offer sealing force, as shown in Figure 1, including valve body 1 and spool
2, the valve body 1 is internally provided with valve core channel 101, and the spool 2 and valve core channel 101 are cylindrical-shaped structure, the spool 2
Adaptation is installed on the inside of valve core channel 101 and the opening and closing realized by moving up and down to valve, and 2 side of spool is set
The sealing structure 3 of rigid seal pair can be formed when it moves down into 101 lower limit of valve core channel closing valve by having, and the spool 2 is another
Side is equipped with multigroup rolled with 101 cylindrical form interior surface of valve core channel and touches and provide elastic group of sealing force to sealing structure 3
Part 4, the 4 installation group of elastic parts is several to be determined according to medium character in gate valve and operating pressure and no less than 4 groups.
Specifically, as shown in Figure 1, every group of elastic parts 4 includes magnetic spring 5 and ball 6, it is corresponding on the spool 2
Side is equipped with installing blind 201, and the magnetic spring 5 is arranged in installing blind 201, and 5 outer end of magnetic spring is connected with and valve body 1
In 101 inner periphery of valve core channel roll the ball 6 that touches.The magnetic spring 5 is by identical two pieces of adjacent surface polarity
Permanent magnet is formed, it is preferred that two pieces of permanent magnets for forming magnetic spring 5 are made of samarium-cobalt permanent-magnetic material.The utility model
Magnetic spring 5 is made of two pieces of identical permanent magnets of adjacent surface polarity, valve is closed when spool 2 moves to valve core channel 101
During position, the effect of 5 mutual expelling force of magnetic spring can be 2 opposite side of spool when providing low pressure for sealing structure 3 needed for sealing
Enough sealing forces, improve valve close when sealing performance；Meanwhile set ball 6, ball 6 and spool in 5 outer end of magnetic spring
101 inner surface of passage is rolled and touched, and so as to reduce the frictional force of the movement in valve core channel 101 of spool 2, reduces mill
Damage, extends valve service life.
The preferred embodiment of above-described embodiment, simply the utility model, is not used for limiting the utility model practical range,
Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model should all be included in
Within enclosing.
