Description
Technical field
The present invention relates to a kind of air regulating device, specifically refer to a kind of gas pipeline volume control device.
Background technology
Pipeline gas transmission station, the various operation posts set up for pipeline conveying natural gas or oil field gas.Stand in pipeline position along the line by calming the anger and be divided into starting point compressor station, intermediate pressure gas station and terminal gas-filling station.Starting point erect-position of calming the anger, near gas collection center, gas field or treatment plant, provides pressure energy for natural gas, and has the operations such as gas purification, gas mixing, pressure regulation, gas dosing, wiper transmission.Intermediate pressure gas erect-position, on transport pipeline is along the line, mainly gives the natural gas boosting consuming pressure energy in conveying.Terminal gas-filling station is positioned at gas storage, mainly sends into underground natural gas storage tank after defeated next natural gas pressurization.
And gas pipeline is the extended stabilizer of pipeline gas transmission station, in natural gas course of conveying, gas flow in pipeline is unstable, duct wall in i.e. transmitting distance on the way is formed and constantly washes away, simultaneously when injecting gas flow and being relatively small, transmit the gas in the pipeline in way and there is also the imaginations such as anti-channeling, and then cause the transmission of gas to be stagnated.
Summary of the invention
It is an object of the invention to provide a kind of gas pipeline volume control device, while realizing the fluid stable circulation automatically controlling in flow in pipes, it is to avoid the gas anti-channeling in pipeline.
The purpose of the present invention is achieved through the following technical solutions:
nullA kind of gas pipeline volume control device，Including valve body、The tubulose movable block of one end closing and end extend to the union joint of valve inner，Union joint connects with the inside of valve body，The external diameter of described movable block blind end is less than the external diameter of its open end，Chute is had on inwall in the middle part of valve body，Movable block open end is slidably arranged in chute，Between movable block blind end and chute, annular space forms runner，Described movable block blind end end face is provided with contact block，The elongated end of described union joint is provided with packing circle，Packing circle is provided with protuberance，Described protuberance is elastic block rubber and triangular in shape，And have on contact block end face and the cannelure insulating circle and protuberance coordinates，Movable block has the venthole with flow passage，Valve interior wall is additionally provided with the annular projection just to movable block open end，And between the end, open end of annular projection and movable block, spring is installed；Gathering sill is had in described chute, movable block open end is provided with multiple roller, roller-coaster is arranged in gathering sill, is separately installed with organ cover at described gathering sill two ends inwall, and two side with movable block open end respectively, the end of two organ covers is connected.
nullChute is had at valve interior wall，Movable block is that one end is closed、The tubular structure that the other end is open，I.e. it is classified as blind end and open end with the midpoint of movable block for critical point，And the external diameter of blind end is less than the external diameter with open end，The open end of movable block is slidably arranged in chute，During use，Gas is entered in valve body by union joint，Now between union joint with the contact block on movable block blind end end face by protuberance and cannelure coordinate realize airtight，Swiftly flowing gas forms impact to contact block，And then drive movable block to move along a straight line，Protuberance is gradually disengaged with cannelure，And spring is gradually compressed，An elastic force contrary with gas flow is produced when deforming upon，To realize the support to movable block，Gas enters in runner along the gap between union joint and contact block，Enter in valve body finally by venthole，Finally realize in pipeline, stablize injection yield increase fluid，Gas in pipeline cannot be re-introduced in union joint simultaneously；Wherein, when the gas flow injected is excessive, the open end end face of movable block contacts with the extreme position of chute, and then the continuing to move to of barrier activity block, the size making the air inlet of runner keeps invariable, and when gas flow instability, movable block constantly can regulate under the support of spring, to ensure that the gap length between union joint and contact block mates the flow velocity size of injection gas, it is achieved to the Automated condtrol injecting gas.
Further, gathering sill is had in chute, and the open end of movable block is provided with multiple roller, and roller-coaster is arranged in gathering sill, when movable block is moved in chute, the friction that the open end of movable block is subject to is become rolling friction from sliding friction, and then reduces the concentrated wear of movable block, reaches the purpose extending movable block service life.Wherein, described protuberance is triangular in shape, and the long limit of this triangle is connected with the end face of sealing ring, when injecting gas, contacting between protuberance with cannelure is unstable with released state, i.e. collision between protuberance and cannelure is the most frequent, both can be caused impaired seriously keeping this type of operating mode for a long time, and protuberance uses quality of rubber materials, itself possess certain deformation and reply the ability of deformation, i.e. realize flexibly connecting between union joint and contact block, avoid between union joint and contact block the most impaired to the full extent.The violent scour of the gas being injected in valve body can be subject to when roller slides in gathering sill, not only make the impaired aggravation of roller, also can affect the movement of movable block, for this, inventor passes through organ cover, and the opening being directed to groove is avoided, and utilized the flexibility of organ cover, ensure that organ covers on to produce deformation when moving in the lump with the open end of movable block and avoid impaired, to improve the regulation efficiency of movable block.
In the inner hollow of described contact block, and the end face of described contact block embedding movable block blind end.As preferably, use the contact block of inner hollow, can directly reduce contact block and the weight of movable block self, the resistance suffered when there is linear motion to reduce movable block, the portable propelling block flexible to injecting gas.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is when the gas flow injected is excessive, the open end end face of movable block contacts with the extreme position of chute, and then the continuing to move to of barrier activity block, the size making the air inlet of runner keeps invariable, when gas flow instability, movable block constantly can regulate under the support of spring, to ensure that the gap length between union joint with contact block mates the flow velocity size of injection gas, it is achieved to the Automated condtrol injecting gas；
2, in the present invention, sealing ring uses quality of rubber materials, itself possesses certain deformation and replys the ability of deformation, i.e. realizing flexibly connecting between union joint and contact block, avoid between union joint and contact block the most impaired to the full extent；
3, the present invention uses the contact block of inner hollow, can directly reduce contact block and the weight of movable block self, the resistance suffered when there is linear motion to reduce movable block, the portable propelling block flexible to injecting gas.
