Description
Technical field
The present invention relates to a kind of plunger valve device, be specifically related to the manual plunger valve dress that a kind of upper lower valve base can seal respectively
Put.
Background technology
Plunger valve is closure member or the rotary valve of plunger shape, is made on the passway on valve plug and valve body by 90-degree rotation
Passway communicates or separates, it is achieved a kind of valve being turned on and off.The shape of the valve plug of plunger valve can become cylindrical or circular cone
Shape.In cylindrical valve plug, passage is the most rectangular；And in cone-shaped valve plug, passage is in echelon.These shapes make plunger valve
Structure becomes light and handy, but also creates certain loss simultaneously.Plunger valve is most suitable as being switched off and on medium and shunting
It is suitable for, but is based on the abrasion-resistance of character and the sealing surface being suitable for, sometimes can also be used for throttling.The plunger valve plug of band through hole
Body is as the valve of opening and closing element.Cock body rotates with valve rod, to realize switching motion.Small-sized packless plunger valve is also called " to be examined
Gram ".The cock body of plunger valve mostly is cone, coordinates composition sealing pair with the conical bore face of valve body.Plunger valve uses the earliest
A kind of valve, simple in construction, switch are rapid, fluid resistance is little.Common plunger valve leans between metallic plug body and the valve body of polish
Directly contact seals, so sealing is poor, hoisting capacity is big, easily weares and teares, can typically be only used to low pressure and small-bore field
Close.Plunger valve is widely used in oilfield exploitation, conveying and concise equipment, is also widely used in petrochemical industry, chemical industry, coal simultaneously
In gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
Existing plunger valve is in runner hole first half valve seat and is in lower half, runner hole valve seat and cannot seal respectively, has
Time can seal bad.
Summary of the invention
The technical problem to be solved is that conventional structure is in runner hole first half valve seat and is under runner hole
Half valve seat cannot seal respectively, it is therefore intended that provides the manual plunger valve gear that a kind of upper lower valve base can seal respectively, solves
It is in runner hole first half valve seat and is in lower half, runner hole valve seat and is required to and sealing, it is difficult to being extruded by lower valve rod
The problem that colleague is ensured.
The present invention is achieved through the following technical solutions:
The manual plunger valve gear that a kind of upper lower valve base can seal respectively, including handle, support, valve rod, valve body, its feature of runner
It is, also includes push rod, valve seat；Handle is perpendicular to push rod axis and is connected with push rod one end, and push rod uses helicitic texture along support
Axis direction is connected with support, support be connected to valve body above perpendicular to valve body, valve body is columnar structured, intermediate cylindrical
Cavity forms runner, and the other end of push rod is connected with one end of valve rod, and the intersection at valve rod axis Yu runner is provided with valve seat.
Valve seat can reduce valve operation moment, drives push rod to move up and down by the action of handle, push rod drive the lifting of valve rod with under
Fall, controls lower valve rod and valve base sealing or disconnection, it is achieved disconnection, the purpose of UNICOM's fluid, uses helicitic texture guidance quality good, if
Standby stability is high, and it is convenient fixing that rack surface has bulge-structure.
Handle uses turning handle, and handle axle center is machined with square hole.Owing to push rod uses helicitic texture to be connected with support, institute
Turning handle is used more to meet the demand of work, laborsaving convenience with handle.
Push rod and handle are connected to one end and are machined with square shaft, and square shaft is connected with the square hole of handle.Use square shaft with square hole even
Connect, stable connection, be difficult to during rotation skid.
One end that push rod is connected with valve rod is provided with slotted eye, and slotted eye mouth is provided with tenon, and valve rod one end extend into push rod
In slotted eye, valve rod is provided with draw-in groove and coordinates with the tenon on push rod.Owing in work process, push rod uses engagement thread and props up
Frame connects to be needed to rotate, and valve rod has only to move up and down without rotation with push rod, uses said structure can ensure that and pushes away
Bar and valve rod relatively rotate in the horizontal direction and cannot relative movement the most freely.
Also including being provided with runner hole on valve seat, weakening groove and plug-hole, valve seat has runner hole, edge along runner axis direction
Valve rod axis direction has plug-hole, has weakening groove on the vertical direction by runner hole with plug-hole.Use the valve seat after weakening,
Can reduce valve operation moment further, the valve seat local that runner hole simultaneously can be allowed upper and lower can seal respectively with valve body.
Valve seat material uses PEEK.The frictional behaviour that PEEK creep compliance is low, elastic modelling quantity is high, excellent, the most wear-resisting, opposing
The erosion of various media, meets FDA certification, nontoxic, the most excellent chemical resistance, fire-retardant.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the manual plunger valve gear that a kind of upper lower valve base can seal respectively, has special valve seat, and valve operation moment is little, with
Time can allow runner hole upper and lower valve seat local can seal respectively with valve body；
2, the manual plunger valve gear that a kind of upper lower valve base can seal respectively, push rod uses with support threadeds, and guidance quality is good,
Stability is high；
3, the manual plunger valve gear that a kind of upper lower valve base can seal respectively, valve seat uses PEEK material, and creep compliance is low, springform
Measure high, excellent frictional behaviour, the most wear-resisting, resist the erosion of various medium.
