Problems solved by technology

When used to seal fluids with low viscosity (such as seawater, fresh water, ethylene glycol, etc.), it is usually necessary to use a cone valve structure, which can only be synthesized by two two-position two-way valves using pipelines or valve plates in parallel. It is a two-position three-way valve group, so the structure is complicated and the cost is high

Abstract

The invention relates to a two-position three-way valve suitable for low-viscosity fluid. The two-position three-way valve comprises a valve body. A valve element is mounted in the middle of the valve body. A valve deck is mounted at one end of the valve body. The outer circumferential face of the valve deck and the valve body are sealed through a second O-shaped ring and a second check ring. The end face of the valve deck is locked with the valve body through screws. One end of the valve element is connected with the valve body in a matched mode, the other end of the valve element is connected with the valve deck in a matched mode, and the two ends of the valve element are mounted through first O-shaped rings and first check rings in a sealed mode. An input port and an output port are formed in the two ends of the valve body. A P1 port and a P2 port are formed in the top of the valve body. The two ends of the front end face of the valve body are sealed through a first plug and a second plug correspondingly. A P port is formed in the part, beside the second plug, of the valve body. The two-position three-way valve is compact and reasonable in structure and convenient to use, the two-position three-way functions are achieved through a cone valve structure form, a two-valve form is not needed, the space is greatly saved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field, in particular to a two-position three-way valve suitable for low-viscosity fluids. Background technique [0002] The two-position three-way valve in the prior art usually adopts the following structural form: it includes a valve core and a valve body, and a slide valve structure with a gap sealing method is used between the two, which can generally only be used to seal fluids with relatively high viscosity. (such as hydraulic oil, lubricating oil, emulsion, etc.). When used to seal fluids with low viscosity (such as seawater, fresh water, ethylene glycol, etc.), it is usually necessary to use a cone valve structure, which can only be synthesized by two two-position two-way valves using pipelines or valve plates in parallel. It is a two-position three-way valve group, so the structure is complicated and the cost is high. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the existing ...
