Problems solved by technology

The pressurized multi-control diverter valve is mainly connected to the pressure source of the actual control system on site to provide a source of conventional pressure. Because the existing pressurized multi-control diverter valve points are many, the pipeline connection is relatively messy, and the operation, transportation and disassembly are relatively troublesome. With relatively concentrated functions, it cannot solve the key problem of simultaneous control of multi-directional and multi-interface under special circumstances

Abstract

The invention discloses an under-pressure multi-control distribution valve which comprises a valve body. A filter cavity and a valve cavity are formed in the valve body and communicate with each other through a connecting channel arranged in the valve body. A filter screen is arranged in the filter cavity through filter screen fixing nuts. The left side of the valve body is provided with an oil inlet communicating with the filter cavity, and is further provided with a left oil outlet. The left oil outlet communicates with the valve cavity through a left oil discharge channel arranged in the valve body. The front side of the valve body is provided with a front oil outlet, and the front oil outlet communicates with the valve cavity through a front oil discharge channel arranged in the valve body. The right side of the valve body is provided with a right oil outlet, and the right oil outlet communicates with the valve cavity through a right oil discharge channel arranged in the valve body. The rear side of the valve body is provided with a rear oil outlet.

Description

technical field [0001] The invention relates to drilling and workover equipment, in particular to a pressurized multi-control diverter valve. Background technique [0002] The pressure multi-control diverter valve is one of the main equipment accessories such as blowout preventer, pressure operation device, wellhead, manifold and so on. It effectively controls the switch of multi-pipeline equipment at the wellhead, which not only implements the effect of multi-control diversion under pressure, but also prevents oil layer pollution and the safety of personnel and equipment, and greatly improves the operation speed of the wellhead. The pressurized multi-control diverter valve can be designed according to the orientation of the real interface, the number of interfaces and the standard specification of wellhead pressure. The pressurized multi-control diverter valve is mainly connected to the pressure source of the actual control system on site to provide a source of conventiona...
