The utility model is related to valve technology field, more particularly to a kind of two way seal ball seat of use V-shaped seal ring structure.This uses the two way seal ball seat of V-shaped seal ring structure, including valve body, bonnet and soft valve seat.A kind of beneficial effect of the two way seal ball seat of use V-shaped seal ring structure that the utility model is related to is：Employ 2 groups of V-shaped seal ring structures between bonnet and valve seat seat ring to seal, the sealing effectiveness of V-shaped seal ring structure more preferably, realizes zero leakage, and material uses PTFE or RPTFE, and corrosion resistance is stronger, wider using scope；Spring base and packing spring are housed between two groups of V-shaped seal rings, the decrement of V-shaped seal ring can be effectively adjusted, it is to avoid the situation appearance that V-shaped seal ring is directly crushed to death；Seating spring provides initial seal pressure to valve seat, it is achieved thereby that the two way seal function of valve seat.
Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of two way seal ball of use V-shaped seal ring structure
Valve base.
Background technology
Typically using the seat design of one-way sealing, i.e. the valve seat at import two ends can block import to present Fixed ball valve
The medium at end, because valve seat is usually designed to self-relieving structure, i.e., when valve body middle chamber pressure anomaly is increased to regulation most
Port of export valve seat will be pushed during high level open to release pressure, such design is caused to prevent body cavity pressure excessive
Danger, have the disadvantage once entrance point valve seat is damaged and if failing, the valve just loses the effect to medium blocking, gesture
Certain loss must be caused to pipe-line system.And the research of two way seal ball seat provides dual protection, using so
Seat design after, even if import valve seat is damaged, outlet valve seat can still play sealing function, and this valve seat construction was both
The sealing effectiveness of ball valve is improve, while also extending the service life of ball valve.And valve body middle chamber designs a bleeder valve to prevent
Only the pressure anomaly of lumen is raised.
Currently, in the market also has many two-way valve seat constructions, but most of sealing structures for using are excessively simple, sealing
Part is fragile, and the frequency that seal is changed is high, therefore overall economic efficiency is low.
Utility model content
In order to overcome defect present in background technology, the utility model solves the technical scheme that its technical problem is used
It is：A kind of two way seal ball seat of use V-shaped seal ring structure, including valve body, bonnet and soft valve seat, the bonnet pass through
Trip bolt is fixed on the both sides of valve body, and the inside of the valve body is provided with spheroid, and the valve body is provided with gear-box, the gear
Case is provided with handwheel, and the soft valve seat is bumped into the valve seat seat ring of valve seat seat ring and spheroid contact site, is set on the bonnet
There is seating spring putting hole, seating spring is provided with the seating spring putting hole, be provided between the bonnet and valve seat seat ring
Multiple V-shaped seal rings, are provided with spring base in the middle part of the V-shaped seal ring, packing spring is provided with the spring base.
" V " the type bottom of the preferred V-shaped seal ring is towards spring base.
The preferred V-shaped seal ring is made up of PTFE material or RPTFE materials.
The preferred seating spring can provide initial seal pressure for soft valve seat and ball seal.
A kind of beneficial effect of the two way seal ball seat of use V-shaped seal ring structure that the utility model is related to is：
1. employ 2 groups of V-shaped seal ring structures between bonnet and valve seat seat ring to seal, the sealing effect of V-shaped seal ring structure
Fruit more preferably, realizes zero leakage, and material uses PTFE or RPTFE, and corrosion resistance is stronger, wider using scope.
2. spring base and packing spring are housed between two groups of V-shaped seal rings, the compression of V-shaped seal ring can be effectively adjusted
Amount, it is to avoid the situation appearance that V-shaped seal ring is directly crushed to death.
3. seating spring provides initial seal pressure to valve seat, it is achieved thereby that the two way seal function of valve seat.
4. two way seal ball valve base structure is reasonable in design, good sealing effect, is adapted to promote the use of.
