The influence of production and a large amount of manpower of needs.
The high-pressure well mouth throttle valve that surges is more demanding, to bear high pressure (as to 15MPa), it is necessary to which increasing valve makes
Reliability improves the degree of automation, reduces labor intensity, specially manufactures and designs for this operating condition situation.
Utility model content:
The purpose of this utility model is to propose that a kind of resistance to high pressure of high-pressure well mouth is surged throttle valve, and it is strong to reduce labour
Degree, specially manufactures and designs for high pressure operating condition situation.
The technical solution of the utility model is, a kind of high-pressure well mouth surges throttle valve, including valve body, valve seat cylinder, valve seat, valve
Core, spool bolt, positioning pin, cylinder body, valve rod, piston, nut, cylinder cap, oil circuit bent sub, oil circuit straight joint；Valve body side is
Valve export, valve body are equipped with import of the valve seat cylinder as valve, and valve seat cylinder is located at body base, are valve seat, valve above valve seat cylinder
The upper end side port valve door outlet of seat cylinder, for spool in valve body inner seat upper direction, spool ends stream when protruding into valve seat cylinder bottom
Body access, spool control the aperture of fluid passage in upward out valve seat cylinder bottom different distance；Spool is serially connected in below valve rod,
Valve rod protrudes into hydraulic cylinder body and fixes with the piston in hydraulic cylinder, and cylinder cap is equipped with oil circuit bent sub and oil circuit straight joint is set respectively
In the top and bottom end of hydraulic cylinder.Either oil circuit bent sub, oil circuit straight joint are located at the top and lower section of piston.
The position that hydraulic cylinder body lower part valve rod stretches out is equipped with one and arrives three seals circle.
Valve body is a tubular, and hydraulic cylinder body is a T word tubular, and T word heavily fortified point straight tube protrudes into tubular valve body, valve rod perforation
In hydraulic cylinder body and tubular valve body；Spool is to be fixed on valve stem end by spool bolt；The upper end of hydraulic cylinder body is cylinder
Lid；For sealing fluid cylinder pressure, oil circuit bent sub and oil circuit straight joint are respectively equipped on hydraulic cylinder and cylinder cap.
When the piston is moving up, when valve rod moves upwards, valve rod band movable valve plug is lifted up, and is opened entire logical
Road injects liquid and the oil recovery of high pressure.When the piston is moving down, valve rod moves downward, and when reaching rest position, closes entire
Channel terminates the liquid injection of high temperature and pressure and recovers the oil.
The utility model has the advantages that the utility model opens and closes valve using hydraulically operated equipment, and it is easy to operate, human cost is reduced,
High efficiency is done, automation control is convenient for.The guide frame extended using T word heavily fortified point straight tube, convenient for guaranteeing the centering of spool.Valve
Bar is equipped with Multi-layer sealing structure in hydraulic cylinder body or in valve seat location, guarantees sealed reliable.Using different types of hard
Matter alloy welding deposit technology keeps sealing surface corrosion-resistant, and impact resistance guarantees the service life of valve.
