Abstract
The utility model discloses a kind of V-type ball valve with elastic seat, it include valve body, spool, the spool is installed in valve body, the valve body includes snout cavity and outlet plenum, the valve body is equipped with elastic seat close to snout cavity side, the elastic seat is in ring piece shape, and in the state of valve closing, the elastic seat presses to be cooperated on spool and in sealing is formed to import cavity direction bending and spool.Cooperated by the elastic force and spool of elastic seat, realizes sealing when valve is closed, widely applicable, suitable for most high and low temperature environment, especially in the high temperature environment, elastic seat is smaller by being influenced, and can remain that the leakproofness of valve seat, leakage rate are small.
Description
Technical field
The utility model relates to ball valve field, specifically a kind of V-type ball valve with elastic seat.
Background technique
V-type ball valve is not only simple in structure, good airproof performance, and has within the scope of certain nominal dimension small in size, again
The advantages that amount is light, material consumption is few, installation dimension is small, easy to operate, easily realize fast opening and closing, and regulation performance is excellent, is nearly ten
In the past few years it is widely used in control valve use.
Currently, most of V ball valves are only used as cutting, cut-off and in fluid circuit to adjust the effect of flow.However, with
The development of valve industry, the function of V ball valve be increasingly difficult to meet the needs of market.Especially under high temperature environment, V-type ball
The valve seat of valve and media contact are because temperature height, sealing ring easily soften, and there are the hidden danger of leakage.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of with elasticity
The V-type ball valve of valve seat, is particularly suitable for hot environment.
The technical solution of the utility model includes: including valve body, spool, the spool is installed in valve body, the valve body packet
Snout cavity and outlet plenum have been included, the valve body is equipped with elastic seat close to snout cavity side, and the elastic seat is in ring piece shape,
In the state that valve is closed, the elastic seat presses in close on spool and in being formed to import cavity direction bending with spool
Envelope cooperation.
By adopting the above technical scheme, cooperated by the elastic force of elastic seat and spool, realize sealing when valve is closed, fitted
With extensive, suitable for most high and low temperature environment, especially in the high temperature environment, elastic seat is smaller by being influenced, energy
Enough remain that the leakproofness of valve seat, leakage rate are small.
The further setting of the utility model: the material of elastic seat is English section nickel that X-750.
Using above-mentioned further setting, which has good elastic property, can guarantee that valve seat is certainly when valve is opened
It is dynamic to reset and small by Effect of Hyperthermic Environment.
The further setting of the utility model: elastic seat side is fixedly installed with the valve seat for fixing elastic seat
Pressing ring, the other side of elastic seat have the convex shoulder protruded from valve interior wall.
Further it is arranged using above-mentioned, valve seat pressing ring and convex shoulder form the fixation to elastic seat, consolidate elastic seat
It is fixed relatively reliable.
The further setting again of the utility model: have close to the valve seat pressing ring side in elastic seat direction and elasticity is provided
The inclined-plane of the valve seat curved space.
Using above-mentioned setting further again, inclined-plane prevents valve seat pressing ring and elastic seat from colliding, makes elastic seat
With space required for being bent.
The further setting again of the utility model: gasket seal is installed between elastic seat and convex shoulder.
Using above-mentioned setting further again, for the gap between sealed elastic valve seat and convex shoulder.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view at the utility model A；
Fig. 3 is the partial enlarged view at the utility model in the on-state A；
Wherein, valve body 1, spool 2, snout cavity 11, outlet plenum 12, elastic seat 3, valve seat pressing ring 4, convex shoulder 13, inclined-plane 41,
Gasket seal 5.
Specific embodiment
It as shown in Figure 1-Figure 3, include valve body 1, spool 2, the spool 2 is installed in valve body 1, and the valve body 1 includes
There are snout cavity 11 and outlet plenum 12, the valve body 1 is equipped with elastic seat 3 close to 11 side of snout cavity, and the elastic seat 3 is in
Ring piece shape, in the state that valve is closed, the elastic seat 3 presses on spool 2 and in 11 direction bending of snout cavity
Sealing cooperation is formed with spool 2, is since spool 2 rotates in this way, elastic seat 3 is squeezed by spool 2 from originally whole vertical
It is deformed into axial direction to 11 direction of snout cavity and is bent, so that elastic seat 3, which is pressed on spool 2, forms sealing cooperation.?
When valve is opened, elastic seat 3 can be reset to perpendicular to axial shape.The elastic seat 3 of ring plate shape, can be perpendicular to axis
To direction, it is possible to have towards the taper of atrium.
The preferred English section nickel that X-750 of the material of elastic seat 3, the material property is good, can also be suitable for use in hot environment.
3 side of elastic seat is fixedly installed with valve seat pressing ring 4, and the other side of elastic seat 4, which has from 1 inner wall of valve body, protrudes
Convex shoulder 13, valve seat pressing ring 4 is packed into the snout cavity 11 of valve body 1 by way of spiral, and elastic seat 3 is made to be against convex shoulder 13
On, to form gripping to elastic seat 3.
There is inclined-plane 41 close to 4 side of valve seat pressing ring in 3 direction of elastic seat, inclined-plane 41 is tilted toward 11 direction of snout cavity,
To provide the required curved space of elastic seat 3, to realize the sealing cooperation of elastic seat 3.
Gasket seal 5 is installed, gasket seal 5 is used for sealed elastic valve seat 3 and convex shoulder between elastic seat 3 and convex shoulder 13
Gap between 13,5 internal diameter of gasket seal and 13 internal diameter of convex shoulder are equal.
