Description
Technical field
The utility model is related to gas voltage regulation of voltage regulation technical field, more particularly to a kind of axial-flow type control preventing piston card resistance
Valve processed.
Background technology
Contain certain dust in natural gas line, dust is also than more serious in some pipelines, and such as axial flow control valve is lived
Plug and adjust sleeve be it is sleeping be mounted in valve body, piston dead weight is downward, when adjusting side-to-side movement in sleeve, piston outer wall and
Sleeve lining meeting phase mutual friction is adjusted, and the general bore of axial flow control valve is all bigger, even up to DN1000, therefore piston is certainly
Weight is very big, and frictional force is very big.Piston and adjusting sleeve are that metal material makes, and metal and metal phase mutual friction surface are easy to draw
Wound causes piston and adjusts card resistance between sleeve, makes valve invalidation.
In the prior art, the applicant in preceding application, Publication No. CN206093010U, the time of disclosure is 2017 4
The moon 12, the Chinese utility model patent document of entitled " high pressure hand-operated steam injection valve " discloses a kind of high pressure hand-operated steaming
Vapour injection valve, it is structurally characterized in that：It is in the stream gradually widened from bottom to up that one group is arranged on valve cylinder in equal percentage curve
Measure adjustment hole, it is ensured that can realize that " percentage of changes in flow rate is equal and with identical on each position point for adjusting stroke
Degree of regulation ", can meet well " variable quantity that adjusts steam flow in small flow is small, big flow when adjust steam
The variable quantity of flow is big " the Technology of Heavy Oil Recovery requirement, have good flow-adjusting characteristics.It is arranged in spool bottom end buffers
Throttle sphere structure, can shunt steam around and extenuate souring to valve chamber internal component.The utility model has structure
It is simple and direct, manufacturing cost is low, degree of regulation is high, stability is good, it is stable, steady to thick oil well heat supply to adjust input steam flow
Outstanding advantages fixed, safe and reliable to operation, with long service life have splendid application prospect in thick oil mining operation.But
It is this technical solution piston and to adjust sleeve be that metal material makes, metal and metal phase mutual friction surface be easy to pull,
It causes piston and adjusts card resistance between sleeve, make valve invalidation.
Invention content
It is kept away using ring type guide support structure, using close interference fit the purpose of this utility model is to provide a kind of
Exempt from the axial-flow type control valve that dust blocks spool.
The purpose of this utility model is achieved through the following technical solutions：
A kind of axial-flow type control valve preventing piston card resistance, including main valve body, be fitted in the valve chamber of main valve body primary valve,
