Description
Technical field
It the utility model is related to rotary motion valve field, and in particular to a kind of angular stroke control valve valve seat, plug sealing structure.
Background technology
Rotary motion valve is a kind of regulating valve, and after its executing agency receives control signal, signal is become into displacement thrust
Or corner torque, to reach the purpose of the switch of control valve.The valve rod of rotary motion valve is done perpendicular to the angle of valve rod with movable valve plug
Spinning movement is spent, usually in 90 degree of scope class crankmotions.Typical product has ball valve, butterfly valve, spherical crown valve, plug valve
Deng.Wherein, spherical crown valve is also known as eccentric rotary valve, caimflex valve, because its flow resistance is small, regulating ratio is big, resistance to erosion, anti-blocking property
The many merits such as energy, materials province, by increasing favor and are applied.But in traditional rotary motion valve valve seat construction, when
When valve element somewhat retreats, it may result in sealing surface of seat and valve element will depart from or seal pressure declines, cause cut-out to fail, be situated between
Matter leaks.
Utility model content
The purpose of this utility model is to provide a kind of angular stroke control valve valve seat, plug sealing structure, existing to solve
Valve element somewhat retreats the problem of may result in cut-out failure in technology, realizes the purpose for making the flexible compensation ability of valve seat.
The utility model is achieved through the following technical solutions：
A kind of angular stroke control valve valve seat, plug sealing structure, including valve body, the valve seat in valve body, and with institute
The valve element that valve seat matches is stated, valve seat set is set in the valve body, the valve seat set is included towards valve inner direction protrusion
Protuberance；The valve seat is arranged at the interior side direction of valve seat set, and valve seat is in contact with the protuberance that valve seat covers；Also include setting
In elastic component of the valve seat away from the side direction of valve element one, one end of the elastic component is connected with valve seat, the connection of the other end and pressing plate, when
When valve seat contacts with valve element, elastic component is in compressive state；The pressing plate is fixed on valve seat and put.
The problem of may result in cut-out failure is somewhat retreated for valve element in the prior art, the utility model proposes a kind of angle
Stroke adjustment valve base, plug sealing structure, including valve body, the valve seat in valve body, and the valve element to match with valve seat.
Valve seat set is set in valve body so that valve seat is located at side of the valve seat set towards valve inner center, and valve is replaced by valve seat set with this
Body carries out spacing to valve seat.Valve seat set is realized to the spacing of valve seat by protuberance so that valve seat is in contact with protuberance, i.e., can
So that the moving range of valve seat is not over protuberance position.Side of the valve seat away from valve element sets elastic component, elastic component
The other end contacted with pressing plate, pressing plate is fixed on valve seat and put again, therefore is that elastic component is connected between valve seat and pressing plate.

Difference, the front and rear of valve seat has a pressure difference during sealing, and pressure difference can push valve seat to valve element, play a part of pressure self-sealing, from
And further improve sealability of the present utility model.
Preferably, the surface that the valve seat is in contact with protuberance is sphere；The table that the protuberance is in contact with valve seat
Face is inclined-plane；The sphere and the inclined-plane are tangent；The inclined-plane favours valve axis.It is to lead between valve seat and protuberance
Cross sphere and inclined-plane is contacted, the inclined-plane refers to favour valve axis, and sphere and inclined-plane are tangent.Due to valve seat and elasticity
Part is connected, therefore has the ability of automatic centering under the resilient force of elastic component.Specifically, when valve element departs from valve seat,
The extruding force that elastic component is subject to is disappeared, and elastic reset power is undertaken by valve seat completely, drives the sphere on valve seat on protuberance
Adjustment position on inclined-plane, so as to automatically return to initial position, valve seat is all in fixed position when ensuring that each valve element is closed with this
On, avoiding long-term use of rear valve base position from deforming can not restore to the situation appearance of initial position, so as to greatly improve
Service life of the present utility model.
Further, in addition to the platen that is fixed on inside valve seat, the platen are located at side of the valve seat set away from valve element
Direction, the valve seat set, pressing plate are connected with platen.Platen is used to valve seat being locked at protuberance, and valve is realized by platen
Close connection between cover for seat, pressing plate and valve body, at the same provide it is spacing, avoid valve seat set with pressing plate produce displacement cause elastic component
Elastic force produce deviation, precision and stability of the present utility model are improved with this.
Preferably, the valve element is coronal sphere core or coronal sphere valve plate.It is easy to be engaged with valve seat and forms angle row
Journey adjustment structure.
Preferably, side of the valve seat away from valve element sets groove, and the elastic component is located in groove.Avoid elastic component
Extra space-consuming is configured, and so as to greatly reduce volume, reduces space-consuming.
Preferably, the elastic component is spring or disc spring.
Preferably, the sealing ring is the one or more in rubber seal, polytetrafluoroethylsealed sealed circle, graphite self sealss circle.
Preferably, a side surface of the valve seat away from valve axis sets seal groove, and the sealing ring is positioned over sealing
In groove.Reduce and take volume and space, at the same using seal groove sealing ring is carried out it is firm with it is spacing, avoid valve seat moving process
Relative displacement occurs between middle sealing ring and valve seat.
Preferably, the platen is loop configuration, is to be threadedly coupled between platen and valve body.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of angular stroke control valve valve seat of the utility model, plug sealing structure, when the fluid media (medium) pressure of Way in
When power increase extruding valve element causes the valve element to retreat, under the elastic reset power effect of elastic component, valve seat can be bonded valve element and follow
Motion, ensure that the sealing surface between valve seat and valve element is in close contact, somewhat retreat and will lead so as to solve valve element in the prior art
The problem of causing cut-out failure, realizes the purpose for making the flexible compensation ability of valve seat.
2nd, a kind of angular stroke control valve valve seat of the utility model, plug sealing structure, when the pressure of fluid media (medium) increases to
When to a certain degree, the surface that the out-of-balance force as caused by pressure medium is in contact by valve seat set with valve seat on valve seat is supported,
So that valve element stress declines, so as to bear bigger out-of-balance force, bigger cut-out pressure difference is realized.
