A pump valve that is easy to install and disassemble and its working method

Abstract

The invention discloses a pump valve with convenient installation and disassembly operation. The pump valve includes a fixed pump casing, a fixed base plate, a turbine rotary vane and a buffer base plate; the fixed pump casing is fixedly installed at the upper end of the fixed base plate, and a water inlet pipe is fixedly connected to the middle position of the outer surface of one side of the fixed pump casing in a sleeved mode; a drain pipe is fixedly connected to the middle position of the outer surface of the upper part of the fixed pump casing in a sleeved mode, upper chucks are fixedly installed on the outer surfaces of one ends of the drain pipe and the water inlet pipe, lower chucks are fixedly connected to the outer surfaces of the bottoms of the upper chucks in a sleeving mode, and combined sleeving chucks are fixedly installed on the inner sides of the upper parts of the upper chucks; and butt joint bolts are fixedly installed on the outer surfaces of the combined sleeving chucks, and two-way clamping grooves are formed in the inner surfaces of the inner sides of the upper chucks. According to the pump valve with convenient installation and disassembly operation, a fastbutt joint structure is arranged, the operation difficulty during installation and disassembly is reduced, a spliced-type fixing structure is arranged, the flexibility during use is improved, and theapplication range is increased.

Description

technical field [0001] The invention belongs to the technical field of pump and valve equipment, and in particular relates to a pump valve that is easy to install and disassemble, and more specifically to a pump valve that is easy to install and disassemble and a working method thereof. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also transport liquid and gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three types according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps.

Problems solved by technology

[0003] An integrated pump valve module disclosed in the comparative document CN104523257A includes a booster pump, an air release valve, an air outlet and an upper cover, the air outlet and the air release valve are arranged on the upper cover, and the upper cover is provided with There is an airflow channel, and the airflow channel communicates with the booster pump, the air release valve and the air outlet, and the air release valve is a solenoid valve; the bottom of the upper cover includes a plurality of annular grooves, and the annular grooves are open downwards, The inner surface of the annular groove is in close contact with the upper end of the piston in the booster pump, and the opposite side of the plurality of annular grooves directly communicates with the opening at the top of the upper cover at the bottom of the groove, and the opening is located on the Under the air release valve, compared with the present invention, it does not have an adjustable and fixed structure, which reduces its scope of application, and at the same time cannot perform cooling operations on its milling cutter

[0004] The existing pump valves that are easy to install and disassemble have certain disadvantages during use. The traditional pump valves that are easy to install and disassemble do not have a fast docking and fixing structure. The disassembly operation increases the difficulty of the disassembly operation of the pump valve, which is not conducive to the user's maintenance operation; at the same time, the traditional pump valve that is easy to install and disassemble does not have a splicing fixed structure, so that a single type of pump valve can be docked and fixed The size of the pipeline reduces the flexibility of the pump valve; at the same time, the traditional pump valve that is easy to install and disassemble does not have a buffer protection structure, and a certain vibration will be generated during the operation of the pump valve. Long-term vibration will reduce the pump valve. The service life will have a certain impact on its stability and bring certain adverse effects to users.
