Abstract

A modular duplex adjusting valve comprises an upper valve rod, a splicing cover, a valve rod nut, a handwheel, a valve cover, a bolt, a nut, a composite filler, a valve body, a lower valve rod, a valve cage, a valve element and a bushing, wherein an inlet and an outlet are coaxially formed in the cylindrical valve body, and the inlet is in the direction vertical to that of the outlet; when the inlet is in the left end in the horizontal direction, the outlet is upward; a cylindrical valve seat which is cage-shaped is arranged on the same straight line with an axis of the inlet; the valve element is mounted in the valve cage, and the inside diameter of the valve element fits that of the valve cage; the valve core is a circular rod which is blocked into the valve seat; an inner cylindrical valve element can be rotated in an outer cylindrical cage type valve seat; the cage type valve seat is in sliding fitting with the cage type valve element; the valve cover is fixed to the valve body through the nut and the bolt; a sealing filler which wraps the valve rod is arranged in the center of the valve cover, and the composite filler and a filler pressing cover are sequentially arranged fromleft to right; the right end of the valve rod extends out from the sealing filler in the valve cover; screw threads are formed in the side surface of the upper part of the valve rod; and the handwheelis arranged on the top end of the valve rod and drives the valve rod.

Description

Technical field: [0001] The invention relates to a composite combined regulating valve, which is suitable for projects such as oilfield exploitation, and is a special valve for controlling blowout control, balancing drilling technology and restoring oil and gas well pressure in oilfield exploitation. Background technique: [0002] With the rapid development of our country's national economy. The demand for crude oil has doubled, and there are more and more valves used to control pipelines, which play a key role in controlling blowout, balancing drilling technology, and restoring oil and gas well pressure in oil field production. Traditional wellhead pipelines use regulating valves, which have large flow resistance, large operating force distance, inconvenient operation and low efficiency. The whole pipeline is very long, which is extremely inconvenient, and the equipment cost becomes larger simultaneously. The spool cannot solve the high resistance of the sealing ring and ...
