Dual-valve-core multiported valve with horizontal layout

Abstract

The invention discloses a dual-valve-core multiported valve with horizontal layout. The dual-valve-core multiported valve comprises tubular valve bodies and a connecting pipe, wherein one valve core is arranged in each valve body; a plurality of circumferentially distributed media inlet pipes are arranged on the circumferential wall of each valve body; each valve core is provided with a valve coreaxial center hole of the and a plurality of valve core axial peripheral holes; the two valve bodies are of the same structure; the axial direction of the connecting pipe and the axial direction of each valve body are both horizontal directions; the circumferential wall of the connecting pipe communicates with a first medium outlet pipe and a second medium outlet pipe; a connecting center pipe anda circumferential channel are arranged in the connecting pipe; the first medium outlet pipe communicates with the valve core axial peripheral holes corresponding to the two valve bodies through the circumferential channel; and the second medium outlet pipe communicates with the valve core axial center holes corresponding to the two valve bodies through the connecting center pipe. According to thedual-valve-core multiported valve, the two valve bodies are connected together through the connecting pipe and are designed to be in the horizontal direction, so that the planar occupation space of the multiported valve is remarkably reduced, a large amount of land is saved, the media inlet pips are multiplied, and the number of oil and gas wells which can be connected is doubled.

Description

technical field [0001] The invention relates to a multi-way valve used for a wellhead or a gas gathering station in the oil and gas field industry, in particular to a multi-way valve with double spools arranged in a horizontal direction. Background technique [0002] The multi-way valve is a rotary valve that connects and controls multiple pipelines. Its basic structure is to install a valve core in the valve body, and rotate the valve core manually or electrically to realize on-off control of multiple channels. [0003] In the more advanced traditional multi-way valve, the axial direction of the valve body is vertical, and multiple horizontal medium inlet pipes (that is, inlet pipes or liquid inlet pipes) are installed on the outer periphery of the valve body along the circumference, and the lower end of the valve body There are two medium outlet pipes (i.e. air outlet pipe or liquid outlet pipe), so that the fluid of one medium inlet pipe among the multiple medium inlet pi...

Problems solved by technology

[0005] The above-mentioned multi-channel selection control device is also a multi-way valve. Due to the circumferential distribution of multiple medium inlet pipes in the horizontal direction, the following problems exist: as the oil and gas wells to be connected (that is, oil wells, gas wells or oil-gas mixed wells, The same below) increases, the number of medium inlet pipes will also increase, the plane of the multi-way valve will take up a lot of space, the pipeline layout will be more complicated, and the increased number will be limited, for example, set 8 on a multi-way valve The medium inlet pipe is basically saturated, and it is difficult to add new medium inlet pipes, which limits the scope of use of the multi-way valve and cannot meet the needs of more oil and gas wells using a multi-way valve
