Embodiment Construction

[0019] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings; it should be noted that: the present embodiments are descriptive, not restrictive, and cannot be used to limit the protection scope of the present utility model.

[0020] A high-pressure adjustable multi-channel distribution valve is composed of a valve body 8, a valve cover 7, a valve core 13, a valve sleeve 14, and a valve stem 2. The valve body and the valve cover are coaxial and installed with bolts 6. A bracket 4 is coaxially installed on the upper part of the cover, and the valve stem is coaxially installed in the bracket through the bearing 16 and the bearing gland 3, and the valve stem protection sleeve 1 is coaxially installed outside the valve stem, and a packing is installed between the valve stem and the valve cover 5. The valve core is hinged at the lower end of the valve stem in the valve body, and radial channels 10 are evenly ...

Abstract

The invention relates to an adjustable high-pressure multiport distributing valve. The distributing valve comprises a valve body, a valve cap, a spool and a valve stem, wherein the valve body and the valve cap are coaxial and are arranged through bolts; the lower part of the valve body is used as the inlet of the runner; a support is arranged on the upper part of the valve cap coaxially; the valve stem is arranged in the support coaxially through a bearing and a bearing cover; a handle is arranged on the bearing cover in the radial direction; the spool is hinged with the lower end of the valve stem in the valve body; radial runners are uniformly distributed on the spool in the radial direction; and distributing pipes are fixed on a radial runner which is arranged outside of the valve body and corresponds to the spool. The adjustable high-pressure multiport distributing valve can satisfy the demands of different pipelines on the regulation of the flow of the medium and ensures that the medium in the pipeline enters through one inlet and leaves through a plurality of outlets; the flow can be better distributed, the distributing valve can act as a main switch, the other sub-valves on the pipeline can be conveniently repaired and displaced, the valve housing type sealing structure is adopted to increase the sealing surface and has better sealing and closing effects; and the distributing valve can be widely used in the high-pressure water injection system of the oil field.

Description

technical field [0001] The invention belongs to valves, in particular to a high-pressure adjustable multi-channel distribution valve. Background technique [0002] At present, the multi-channel distribution valve adopts the fixed channel type, which only realizes the liquid distribution of one inlet and multiple outlets, and cannot adjust the flow rate, nor has the closing function; for high-pressure fluid media, the loss of the actuator parts of the distribution valve is relatively large. Therefore, the existing multi-channel distributing valve has less functions and has structural defects. [0003] By searching, there are no published documents that overcome the above problems. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-pressure adjustable multi-channel distributing valve with the functions of adjusting, closing and balancing the pressure in the cavity. [0005] The purpose...
