Five-surface valve structure

Abstract

The invention discloses a five-surface valve structure. The five-surface valve structure comprises a valve shell; the valve shell is a hollow cylindrical structure; a thread is arranged at the middle section of the inner wall of the valve shell; five ports are formed in the outer periphery of the valve shell; a valve element is positioned in the valve shell, and is fixed through an upper cover; the valve element consists of an upper valve element, a fixed part, a lower valve element, a spring and a buckle part; the fixed part is fixed at the middle section of the inner wall of the valve shell through a thread, and is provided with a through hole in center; the buckle part is positioned in the through hole; a push column is arranged on the lower valve element; the top end of the push column penetrates through the buckle part positioned in the center of the fixed part; the upper valve element has a spring positioning column; and the spring coats the spring positioning column, one end is butted against the buckle part in the center of the fixed part, and the other end is butted against an upper valve element body. The five-surface valve structure controls connection and disconnection among other three ports through the pressure magnitude between a pure water inlet and a pure water outlet, and replaces a power utilization control valve; and the buckle part can enable the spring to immediately bounce to quickly switch water ways, so that a RO water purifier can realize powerless operation.

Description

Technical field [0001] The invention belongs to the technical field of water purification equipment, and particularly relates to a five-sided valve structure. Background technique [0002] At present, RO water purifiers on the market generally require electricity-based control valves to control the water inlet and outlet of the water purifier, such as solenoid valves. However, the charged RO machine must be installed in a place with a socket, and the use space is limited. Since the whole machine is running with electricity, it needs to consume energy, and water and electricity are running in the whole machine at the same time, there is a risk of water leakage and electricity leakage. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems and provide a five-sided valve structure that does not require a power source and can control water in and out through water pressure. [0004] To this end, the technical solution of the pres...

Problems solved by technology

[0002] At present, the RO water purifiers on the market generally need control valves that use electricity as energy to control the water in and out of the water purifiers, such as solenoid valves, etc., but the charged RO machines must be installed in places with sockets, and the use site is limited. Because the whole machine is running with electricity, it needs to consume energy, and water and electricity run in the whole machine at the same time, there is a risk of water leakage
