Description
Technical field
The utility model is mainly a kind of anti-wear valve of the double containment for oil and gas industry, is suitable for natural
Gas, oil field pipeline valve, it is special especially suitable for the conveying of some high-pressure natural gas containing sand, oil transportation containing sand etc.
Operating mode.
Background technology
In the industries such as oil, coal, metallurgy, chemical industry, the application of valve is very extensive, due to containing a large amount of in pipeline
Granular material and ore in sand form, so being more serious to the abrasion of valve in pipeline, especially in oil and gas industry, valve
Wear problem is especially prominent, and by taking natural gas sediment outflow as an example, quartz sand with high hardness is contained in natural gas, interior during sediment outflow
External differential is larger, and gravel will produce flow at high speed impact and abrasion in pipeline valve flow at high speed, in spool, valve seat, lead to valve
The serious erosive wear in door sealing face and valve seat, so that sealing surface failure leaks.Usually contain hard particles in this high pressure
Operating mode under, valve service life length can reach 3 months, short then 2 weeks to 3 weeks time, while present every profession and trade is to valve
Automaticity requirement is higher and higher, and it is also more stringent to open and close requirement of the increase of frequency to valve.Entire petroleum gas row at present
Industry using it is more be ball valve, and ball valve will also use high alloy to spray under this special operation condition, but due to ball valve
Special construction is susceptible to stuck phenomenon, and, replacement frequency also poor even across the ball valve erosion-wear-resisting effect of spraying
Also higher.Simultaneously in some coal industries pipeline transfer valve door wear problem also than more serious.Due in raw coal there is
The higher mineral of hardness, such as quartzite（HV900-1280）, pyrite（HV750-900）, feldspar（HV600-750）Deng.These
The hardness of mineral is more than medium and low carbon steel quenching hardness（HV450-600）, very high hard of wear rate is generated after being acted on piece surface
Abrasive wear.The hardness such as lime stone, apatite in spoil are mostly in HV（450-550）, and generate the mill of heavier abrasion
How material, solve the problems, such as this erosion resistance, extend the service life of valve, be current energy industry urgent problem to be solved.
Also the rapidly improving there is an urgent need to valve gate technology of China's economic development at present, although each factory of China's valve industry
Family just gradually increases scientific research and exploitation dynamics, but falling behind in product technology so that competition is not capable, and the valve kind of production is only
The market demand 70% or so can be met.Especially in energy industry, valve products that are to be developed or just manufacturing experimently all are not met by use
The requirement of operating mode.
Invention content
The technical problem to be solved by the utility model is to provide a kind of erosion-wear-resistings, and good airproof performance, service life is long,
Valve simple in structure.
To solve the technical problem, technical solution provided by the invention is as follows：A kind of Double sealed wear resistance damage valve, packet
Include flange, entrance cavity, erosion control pipe nipple, enclosuring structure, wedge shape valve core, plate, upper valve body, connection seal cap, fluid cavity, arc
Erosion control pipe nipple is arranged in the parts such as shape outlet plenum, the flange entrance cavity segment, and erosion control pipe nipple installation position is tied close to sealing
Structure, the enclosuring structure are arranged in parallel in entrance cavity end, and enclosuring structure is provided with wedge shaped fluid-through port, is used on the outside of fluid-through port
Tungsten carbide sprays alloy, and the fluid-through port is inserted into wedge shape valve core, and the wedge shape valve core connects plate main valve, wedge shape valve core and plate
Main valve is linked together, and connects a kinematic axis jointly, the setting of plate main valve is in arc outlet plenum front, with inserting for valve base
Board slot constitutes plate chamber, and plugboard trough bottom end is provided with gasket seal.Fluid cavity is formed between main valve and secondary valve, the fluid cavity connects
Arc outlet plenum is connect, fluid cavity and arc outlet plenum are all sprayed using tungsten carbide.Valve base connects upper valve body, connection type
It is connected by screw bolts.The upper valve body is provided with kinematic axis sliding cavity, and the kinematic axis for connecting plate passes through up and down in sliding cavity
Sliding opens and closes valve.The upper valve body top setting connection seal cap, gasket is arranged in seal cap lower part.The top is arranged
Handle is slided, manual opening-closing can be carried out, while can also connect electric operator.
The erosion control pipe nipple is in semielliptical type, and surrounding is opened there are four square hole, and entire erosion control pipe nipple uses alloy material, weldering
It is connected on entrance cavity wall surface.On the one hand the setting of erosion control pipe nipple prevents band solid particulate matter fluid from directly impacting valve body and runner,
Next, which makes the fluid of entrance cavity form turbulence effects, reduces abrasion caused by impact.
The enclosuring structure is parallel to be welded in entrance cavity end, mainly changes flow direction, while being provided with wedged hole, can be with
Wedge shape valve core carries out fitted seal, while using the alloy material of tungsten carbide spraying in end face.
The progress effect of the utility model is：Using the structure of double spool single valve axis, in valve opening and closing moment to valve
Sealing surface forms protection, while the setting of double spool is also greatly to enhance for sealing effect.It is short secondly by setting erosion control
Section avoids the fluid with particulate matter from directly forming impact to valve body and entrance cavity runner, reduces erosion effect, while erosion control is short
The use of section makes the effect that turbulent flow is formed into the fluid of air stream enter runner, reduces the abrasion that impact is formed.The improvement of dual structure is to valve
Have for the antiwear property of door and greatly promoted, increases the keying number of valve, increase the service life of valve, substantially increase
Economic benefit.
