Abstract

The invention discloses a mechanical vacuum liquid level control valve. The mechanical vacuum liquid level control valve comprises a fixing part, a valve body and a triggering part, wherein the fixingpart comprises a base used for fixing and installing and a guide pipe vertically arranged on the base, the valve body is arranged at the top end of the guide pipe, a working hole, a negative pressurehole and an emptying hole which communicate with one another are formed in the valve body, the working hole, the negative pressure hole and the emptying hole communicate with one another through a connecting cavity, a magnetic bead is movably arranged in the connecting cavity, the negative pressure hole is vertically formed, the emptying hole communicates with the interior of the guide pipe, thetriggering part comprises a triggering assembly and a floating assembly arranged at the bottom of the triggering assembly, the triggering assembly is movably arranged in the guiding pipe in the axialdirection of the guide pipe, the bottom end of the triggering assembly penetrates out of the base in a sliding mode, a magnetic block is arranged at the top end of the triggering assembly, and the magnetic block and the emptying hole are coaxially arranged. The mechanical vacuum liquid level control valve is simple and reasonable in structure, low in manufacturing cost, free of electricity, reliable in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a mechanical vacuum liquid level control valve. Background technique [0002] As people's awareness of environmental protection continues to increase, the use of domestic waste water decentralized vacuum collection technology is becoming more and more widespread. The traditional scheme of vacuum collection at scattered points is: set up a riser at the scattered point, domestic sewage flows into the riser through gravity flow, and the vacuum interface valve is installed on the drainage pipe between the riser and the vacuum sewage tank. There is a liquid level sensor on the lifter. After the liquid level sensor detects a high liquid level, the three-way solenoid valve is controlled by the controller to open the vacuum interface valve, and the waste water in the lifter is sucked by vacuum, and the sewage in the lifter is sucked. Store in a vacuum sewage tank. Using this sol...
