Abstract
The invention discloses a sandwich valve which comprises a main valve body, an auxiliary valve body, a valve plate, a valve rod and a valve seat. The upper end of the main valve body and the upper end of the auxiliary valve body are connected together, and the lower end of the main valve body and the lower end of the auxiliary valve body are connected together. The valve rod and the valve plate are assembled between the main valve body and the auxiliary valve body. The side, facing the main valve body, of the auxiliary valve body is provided with a concave part. A cavity is defined between the valve plate and the concave part of the auxiliary valve body. The valve seat is arranged in the cavity, and the valve seat and the auxiliary valve body are limited in the vertical direction. A valve seat hole corresponding to a valve plate hole of the valve plate is formed in the valve seat. One side face of the valve seat is connected with the auxiliary valve body, and face sealing is conducted on the other side face of the valve seat and the side face of the valve plate. According to the sandwich valve, face sealing is achieved between the valve plate and the valve seat of the sandwich valve, and therefore even if part of the sealing portion is damaged, the peripheral portion can continue to play a sealing role, and the service life of the sandwich valve is prolonged. Shearing motion is carried out between the valve plate and the valve seat, and solid media adhering to the valve plate or the valve seat can be cleaned away quite easily.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of sandwich valve.
Background technique
Valve (famen) is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.
For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve (201,304,316 etc.), Cr-Mo steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized material such as valve such as grade.
Wherein, sandwich valve is the special valve for shutoff operation on pipeline, is arranged in the shutoff threeway on pressure line, is used for taking up perforator and carries out press and open holes, uses plugging device shutoff pressure line, has carried out the operations such as the repairing of pipeline, construction.Also in pigging operation, the MEDIA FLOW in a certain pipeline section region can be intercepted or dredged.
Existing valve many employings linear sealing structure, under action of a fluid, sealing position is easily damaged, and affects the working life of valve.In addition, on existing valve body, the solid dielectric be bonded on valve plate or valve seat is not easy cleaned, easily causes wearing and tearing.
Summary of the invention
For the problems referred to above, the invention provides a kind of sandwich valve, to solve the problems of the prior art.
To achieve these goals, technological scheme of the present invention is as follows:
Sandwich valve, it is characterized in that, comprise main valve body, auxiliary valve body, valve plate, valve rod and valve seat, described valve rod is connected with valve plate, main valve body, auxiliary valve body upper, lower end is connected to together, valve rod, valve plate is assemblied between main valve body and auxiliary valve body, described auxiliary valve body is provided with a depressed part towards the side of main valve body, a cavity is defined between valve plate and the depressed part of auxiliary valve body, described valve seat is arranged in described cavity, and it is spacing at vertical direction between valve seat and auxiliary valve body, valve seat is provided with the valve seat orifice corresponding with the valve plate hole of valve plate, one side of valve seat is connected with auxiliary valve body, the another side of valve seat is that face seals between valve plate side.
In the present invention, the aperture, valve plate hole of described valve plate is consistent with the valve seat orifice aperture of valve seat.
In the present invention, a side of described valve seat is connected with auxiliary valve body by elastic device.
In the present invention, described main valve body bottom is provided with pollutant exhaust hole, is provided with blowdown valve in pollutant exhaust hole.
In the present invention, described upper part of the main valve body be provided be communicated with described cavity from Decompression valves.
In the present invention, the spacing limited step of vertical direction is provided with between described valve seat and auxiliary valve body.
Sandwich valve of the present invention, the face that the is sealed into sealing between its valve plate and valve seat, corresponding linear sealing (as ball valve etc.), even if part sealing position is damaged, the part of periphery can continue to play seal action, the working life of the sandwich valve of raising.
When valve plate valve rod control under open and close up and down time, the motion between valve plate and valve seat is shearing motion, the solid dielectric be bonded on valve plate or valve seat be easy to cleaned fall.This structure makes the solid diameter between valve plate and valve seat very little, rubs little, extends the working life of sandwich valve.
Between valve seat and auxiliary valve body, be provided with elastic device, the wearing and tearing between valve seat and valve plate can be made up, realize zero leakage.
Because aperture, valve plate hole is consistent with valve seat orifice aperture, when valve plate standard-sized sheet, the sealing surface Hide All of valve plate and valve seat, can not be subject to the impact of ring, extends the working life of sandwich valve.
The detailed description and obtaining that feature of the present invention can consult the graphic and following better mode of execution of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the structure cut-away view of sandwich valve of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
See Fig. 1, a kind of sandwich valve, mainly comprises main valve body 3, auxiliary valve body 1, valve plate 11, valve rod 8 and valve seat 2, and the lower end of valve rod 8 is connected with valve plate 11, and the upper end of valve rod 8 connects a handwheel 10.
The upper and lower end of main valve body 3, auxiliary valve body 1 is connected to together, valve rod 8, valve plate 11 are assemblied between main valve body and auxiliary valve body, auxiliary valve body is provided with a depressed part towards the side of main valve body, a cavity 7 is defined between valve plate and the depressed part of auxiliary valve body, valve seat 2 is arranged in described cavity 7, and spacing at vertical direction between valve seat and auxiliary valve body, in the present embodiment, between valve seat and auxiliary valve body, be provided with the limited step that vertical direction is spacing.
