Abstract

The invention discloses a water-based proportional decompression overflow valve. The water-based proportional decompression overflow valve comprises a valve body, a valve sleeve, a decompression valve element, an overflow valve element, an elastic piece and an electric-mechanical conversion element, wherein the valve body is provided with a liquid supply channel, a decompression channel and an unloading channel, the valve sleeve is installed in the valve body and provided with a liquid supply cavity, a decompression cavity and an unloading cavity, the decompression valve element is slidably connected to the valve body, the unloading cavity is divided into a first cavity and a second cavity, the first cavity communicates with the decompression cavity, the second cavity communicates with the unloading channel, the overflow valve element is located in the first cavity and connected to the decompression valve element, the decompression valve element can drive the overflow valve element to move so that an overflow valve opening can be conveniently opened, the elastic piece presses the overflow valve element in the direction of closing the overflow valve opening, and the electric-mechanical conversion element is in driving connection with the decompression valve element. The water-based proportional decompression overflow valve has the advantages of being low in machining and assembling difficulty and stable in output pressure of an decompression valve opening.

Description

technical field [0001] The invention relates to the technical field of proportional pressure reducing valves, in particular to a water-based proportional pressure reducing and overflow valve. Background technique [0002] In the prior art, the proportional pressure reducing valve is generally an oil-based proportional pressure reducing valve. In the oil-based technology, the proportional pressure reducing valve is mostly based on the slide valve structure, mostly with an integrated valve core and a stepped structure of the valve cavity. The stepper motor directly drives the pressure reducing valve core to control the opening of the pressure reducing valve port to realize the outlet pressure reducing function. However, this kind of slide valve structure is not suitable for water-based media, because water has low viscosity and poor lubricating performance, and is more sensitive to the slide valve fit clearance. If the clearance is too large, the leakage will be serious; if t...
