Description
Technical field
The present invention relates to a kind of air regulating device, specifically refer to the throttle structure of long distance pipeline.
Background technology
Pipeline gas transmission station, the various operation posts set up for pipeline conveying natural gas or oil field gas.Stand in by calming the anger
Pipeline position along the line is divided into starting point compressor station, intermediate pressure gas station and terminal gas-filling station.Starting point calms the anger erect-position in the gas collection of gas field
Near the heart or treatment plant, provide pressure energy for natural gas, and have gas purification, gas mixing, pressure regulation, gas dosing, clearly
The operations such as pipe device transmission.Intermediate pressure gas erect-position, on transport pipeline is along the line, mainly gives the sky consuming pressure energy in conveying
So gas supercharging.Terminal gas-filling station is positioned at gas storage, mainly sends into underground natural gas storage tank after defeated next natural gas pressurization.
Gas flow and gas pipeline is the extended stabilizer of pipeline gas transmission station, in natural gas course of conveying, in pipeline
Instability, the 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 the throttle structure of long distance pipeline, automatically control the stream in flow in pipes in realization
While body stably circulates, it is to avoid the gas anti-channeling in pipeline.
The purpose of the present invention is achieved through the following technical solutions:
The throttle structure of long distance pipeline, tubulose movable block and the end closed including valve body, one end extend to valve inner
Union joint, union joint connects with the inside of valve body, and the external diameter of described movable block blind end is less than the external diameter of its open end, at valve
Having chute on inwall in the middle part of body, movable block open end is slidably arranged in chute, ring between movable block blind end and chute
Empty formation runner, is provided with contact block on described movable block blind end end face, and the elongated end of described union joint is provided with packing circle,
Being provided with protuberance on packing circle, described protuberance is elastic block rubber and triangular in shape, and has on contact block end face
The cannelure coordinated with packing circle and protuberance, has the venthole with flow passage, on movable block on valve interior wall
It 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, bullet is installed
Spring；Having gathering sill in described chute, be provided with multiple roller on movable block open end, roller-coaster is arranged on gathering sill
In.
Having chute at valve interior wall, movable block is the tubular structure that one end is closed, the other end is open, i.e. with movable block
Midpoint is that critical point is classified as blind end and open end, and the external diameter of blind end is less than the external diameter with open end, movable block
Open end is slidably arranged in chute, and during use, gas is entered in valve body by union joint, and now union joint is closed with movable block
Realizing airtight by coordinating of protuberance and cannelure between contact block on end end face, swiftly flowing gas is to contact block shape
Becoming impact, and then drive movable block to move along a straight line, protuberance is gradually disengaged with cannelure, and spring is gradually compressed,
Produce an elastic force contrary with gas flow when deforming upon, with the realization support to movable block, gas along union joint with connect
Gap between contact block enters in runner, enters in valve body finally by venthole, finally realizes stable note in pipeline
Entering stimulation fluid, the gas in pipeline cannot be re-introduced in union joint simultaneously；Wherein, excessive when the gas flow injected
Time, 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 so that runner
The size of air inlet keeps invariable, and when gas flow instability, movable block constantly can regulate under the support of spring, with
Ensure that the gap length between union joint and contact block mates the flow velocity size injecting gas, it is achieved to the automatization injecting gas
Control.
Further, in chute, have gathering sill, and the open end of movable block is provided with multiple roller, and roller-coaster
Being arranged in gathering sill so that when movable block moves in chute, the friction that the open end of movable block is subject to is become by sliding friction
For rolling friction, and then reduce the concentrated wear of movable block, reach 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, and protuberance and annular
Contact between groove is unstable with released state, i.e. collision between protuberance and cannelure is more frequent, is keeping long-time
This type of operating mode both can be caused impaired seriously, and protuberance use quality of rubber materials, itself possess certain deformation and reply
The ability of deformation, i.e. realizes flexibly connecting between union joint and contact block, avoids union joint and contact block to the full extent
Between the most impaired.
In the inner hollow of described contact block, and the end face of described contact block embedding movable block blind end.As preferably, adopt
With the contact block of inner hollow, can directly reduce contact block and the weight of movable block self, straight in generation to reduce movable block
Resistance suffered during line motion, 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, and the open end end face of movable block contacts with the extreme position of chute, enters
And the continuing to move to of barrier activity block so that the size of 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 injection gas
Flow velocity size, it is achieved to inject gas Automated condtrol；
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, avoids 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, with fall
The resistance that low movable block is suffered when there is linear motion, the portable propelling block flexible to injecting gas.
