Description
Technical field
The invention belongs to regulating valve technical fields, are related to a kind of double guiding single-seat adjusting valves of multichannel.
Background technique
Regulating valve is that the control in industrial automation process control field, by receiving regulation unit output is believed
Number, the final control element for changing the technological parameters such as rate-of flow, pressure, temperature, liquid level is removed by power operation, regulating valve
The quality of sealing service performance directly affects the quality and economic benefit of final product, one of general regulating valve structure
For the structure (see Fig. 1) of single seat plunger type, but such regulating valve has following disadvantage, first is that this kind of regulating valve is by changing
Become the size of annulus area ready-made between plungers valve core and valve seat to adjust the size of flow in pipeline, so such adjusting
Valve structure limitation can not accomplish big negotiability, second is that because such regulating valve sealing surface just at fluid outlet
Place, fluid flow rate is highest at this time, and is directly washed at sealing surface, if having impurity or pressure difference bigger in fluid
When can generate cavitation erosion, critical seal face can be caused to damage, so influence sealing performance, third is that such valve aperture is DN80's
The high reliablity performance applied under operating condition is stablized, if being greater than DN80 using bore would tend to occur spool vibration and rotation,
Main cause is spool lower end without guiding, spool by the impact force of fluid it is big caused by, the present invention is exactly in conventional plunger formula
Regulating valve on the basis of further do to improve and solve the normal problem of conventional plunger formula regulating valve and improve such regulating valve
Service performance and reliability.
Summary of the invention
The object of the invention are as follows: to overcome plunger type regulating valve fluid capacity in the prior art small, sealing surface easily washes away, valve
The problems such as core easily shakes and rotates provides a kind of double guiding single-seat adjusting valves of multichannel.
To achieve the goals above, the technical scheme adopted by the invention is as follows:
A kind of double guiding single-seat adjusting valves of multichannel including valve body, the valve deck that is mounted on valve body upper end, are mounted in valve body
One end of valve seat, spool and the connecting rod in portion, the connecting rod connects spool, and the other end is pierced by from the valve deck.Spool packet
It includes guide part and connects the sealing being arranged in guide part top end surface, be equipped with sealing at the sealing and valve seat cooperation
Face.Guide part is the guide groove that multi-clove type structure and valve end are equipped with vertical direction, and the cross-sectional profiles line of valve mouth is arc, valve
The Xray films line of mouth is made of the transition part of top connection sealing surface bottom end with the arc sections for being connected to transition part bottom end.Valve
Spool bore is opened up in seat, sealing surface of seat is set in spool bore, the spool bore inner wall below sealing surface of seat is equipped with and leads with described
The guide post cooperated to slot.Spool is located in valve seat spool bore, and valve core sealed cover and sealing surface of seat cooperate.
Make valve core sealed cover and sealing surface of seat simultaneously far from fluid impact, as what is advanced optimized, the vertical of valve mouth is cut
Angle between the tangent line and valve core sealed cover on the arc sections top of facial contour line is 2-3 °, and the height of transition part is 1-2mm.
It advanced optimizes, the valve end of guide part is equipped with the guide groove of vertical direction, the valve below the sealing surface of seat
Core bore inner wall is equipped with the guide post cooperated with the guide groove.Optimized by this step, cooperated between two kinds of structures, made
With the rotation that can prevent spool when being on the one hand the lateral force when spool by fluid, second is that the process to move up and down in spool
In, the stability for playing the role of guiding and then offer spool also avoids spool vibration.
The Xray films line obtained by the present invention for having the beneficial effect that 1) valve mouth is designed as transition part and adds arc sections,
Purpose is for when fluid is by valve mouth, arc sections serve as fluid and change flow direction, final fluid by the effect of guide face
Flow velocity direction by the effect exit of valve mouth is exactly the direction of guide face exit tangent line, and the wherein design of transition part can be with
So that the sealing surface of spool key is reduced the impact force even remotely from fluid by the impact force of fluid, and then also avoids fluid pair
The strength of sealing surface is washed away, and can guarantee that the sealing station of valve seat is in the lower section of primary flow region always, will not
By the impact of fluid, the design of spool valve seat construction of the invention also goes out 1.5 with regard to upper eminence than conventional structure service life
Times or more.2)
Conventional cylindrical pistons formula valve core structure and three-clove style valve core structure of the invention are compared, can significantly find out phase
Under same valve-seat diameter and valve stroke, the circulation area of multi-clove type spool of the invention is obviously than conventional plunger type spool
Annulus area is big.
