Abstract

The invention discloses a non-impact high-pressure multi-to-one valve, and belongs to the technical field of hydraulic valves. The non-impact high-pressure multi-to-one valve comprises a valve body, avalve cavity penetrating through two ends of the valve body is formed in the valve body, a plug connected with one end a spring seat is arranged at one end of the valve cavity, a liquid outlet jointis arranged at the other end of the valve cavity, a plurality of liquid inlet channels communicating with the valve cavity are arranged on the side wall of the valve body, one-way valve cores are arranged in the liquid inlet channels, the spring seat is arranged in the valve cavity of the valve body, and a plurality of springs which abut against the one-way valve cores are correspondingly arrangedon the side wall of the spring seat. The non-impact high-pressure multi-to-one valve has a reasonable structure design, the product of valve blocks is small, reliable function, no impact, high-pressure resistance and small leakage are achieved, and the valve blocks can be connected in series through a straight joint to overlay to meet different use requirements.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, more specifically, it relates to a non-impact high-pressure multi-choice valve. Background technique [0002] In the hydraulic system, to realize the function of choosing one from many, it is generally realized through the shuttle valve. Among the existing shuttle valves, the structural form is a three-way shuttle valve, and one of the two forms is selected, that is, the oil flows in from the A port, blocks the B port through the steel ball, and then flows out from the C port, or flows in from the B port, and is blocked by the steel ball. A port is blocked, and then flows out of C port. The other is a multi-choice shuttle valve, and its structure is also superimposed in the form of a three-way shuttle valve, that is, the oil flowing out of the C port of the shuttle valve is passed to the A port or B port of another shuttle valve, and the two Or multiple three-way shuttle valves are des...
