Embodiment Construction

[0014] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The valve body 5 is a cuboid, and there are bosses with conical external threads on the two surfaces perpendicular to each other. In the middle of the bosses, there are oil ports 10 connected to the accumulator, oil ports 11 connected to the system oil source, two oil ports 10, 11 The centerline of the centerline is in the plane of Gang 1, and the lower surface has the oil port 12 connected to the oil tank, and the other surface opposite to the oil port 10 is an opening with internal thread, and the other surface opposite to the oil port 11 has a communication channel with the oil port 10. Holes, seat holes 17, unloading runners 18, and the oil port 10 in the middle of the valve body and the opening are stepped holes that communicate with each other, and the upper surface has a through hole that communicates with the middle stepped hole.

Abstract

One kind of safety valve group, and the spatial control valve and the discharge valve function to a body, specially is suitable in the petroleum guards against in the jet hydraulic system, took and gathers can its product necessary use special-purpose valve, partially is composed by the control valve part and the discharge valve, states the valve body is an end aperture, middle has the cavity the overall construction, and with stops up connects the whole the valve group body, states on the valve body has mutually has the right angle two circular cones external screw thread raised, between raised Taichung has in a post plane two oils mouths, states ball valve core in vitro as a result of its coordination, Seals the constitution by the outside package of skeleton ball the packing assembly, installs in valve group in vivo. Because directly processes on the valve body protrudes the valve body to have the mouth raised, and the oil mouth directly with the system oil source, the accumulator connection, reduced outside the valve body components machine to divulge the link, caused its structure compact, volume small, matched the tube conveniently, reasonable, seal effect good, the use was safer, reliable.

Description

technical field [0001] The invention relates to a composite valve composed of a control valve and an unloading valve, which is especially suitable for use as a special safety valve group matched with accumulator products in the oil blowout preventer hydraulic system. In addition, the valve can also be widely used in various hydraulic systems using accumulators, as a safe, efficient and special safety valve group for accumulator charging and unloading. Background technique [0002] In the current petroleum industry, in order to prevent blowouts, safety precautions are required, that is, blowout preventers are installed in the oil circuit of the system and controlled by a control valve. The control valve used is actually an ordinary ball valve. It plays the role of opening and closing the switch valve. If the accumulator used with it breaks down, you can only close the ball valve first, stop the oil supply, and then slowly remove the accumulator for maintenance. During this p...
