Copper valve for backwash filter

Abstract

The invention discloses a copper valve for backwashing filter, which comprises a casing, a conduit is arranged in the middle of the casing, the conduit is arranged through the inside of the casing, and is fixedly connected with the casing, The end of the conduit is provided with a magnetic isolation net, and the magnetic isolation net is covered and arranged on the guide tube, and is fixedly connected with the conduit by screws. The bottom of the magnetic isolation net is provided with a fixed block, and the fixed The middle position of the block is provided with a sewage discharge key, which is embedded in the fixed block and fixedly connected with the fixed block. The bottom end of the sewage discharge key is provided with a differential pressure key, and the differential pressure key A ventilation hole is provided at the bottom of the ventilation hole, a pressure gauge and a water outlet are provided on the opposite side of the ventilation hole, and a water inlet is provided at the bottom of the water outlet. Equipped with a cleaning valve, it is convenient for the user to flush the shell and reduce the maintenance cost.

Description

technical field [0001] The invention relates to the technical field of copper valves, in particular to a copper valve for backwashing filters. Background technique [0002] The so-called copper valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. The copper valve is a control component in the fluid conveying system. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] However, the existing copper valve has poor filtration ability, cannot completely filter impurities, and reduces the quality of water source. The structure is not modular, and it needs to be used together with external devices, which increases the cost, poor corrosion resistance, low pressure bearing capacity, and complex structure. Discontinuous exhaust, easy to damage internal components, high maintenance, short se...

[0003] However, the existing copper valve has poor filtration ability, cannot completely filter impurities, and reduces the quality of water source. The structure is not modular, and it needs to be used together with external devices, which increases the cost, poor corrosion resistance, low pressure bearing capacity, and complex structure. Discontinuous exhaust, easy to damage internal components, high maintenance, short service life, no backwashing function
