Abstract

The invention provides a valve with a filtering device, and solves the problem that in the prior valve, sundries accumulate at the bottom of the valve, so that a valve secondary seal is corroded and broken, and the valve loses the function. The valve comprises a valve body [2]; the valve body [2] is provided with a water inlet [3] and a water outlet [1]; and the water inlet [3] and the water outlet [1] of the valve are provided with filter screens [4] for sealing the water inlet [3] and the water outlet [1]. The valve can effectively solve the problem of the functional failure of the valve caused by the sundries and effectively reduce the production and maintenance cost.

Description

technical field [0001] The invention relates to a valve of a regulating or shutting device on a pipeline, especially a valve with a filtering device. Background technique [0002] Valves are widely used in water supply and drainage, sewage treatment, food, medicine, industrial and mining, chemical industry, metallurgy and other industries as general equipment for regulating or shutting devices on fluid pipelines. The key to valve quality lies in sealing. Therefore, in the process of valve manufacturing, transportation and storage, protecting the sealing pair of the valve is an important task to protect the valve. When the valve is installed in the pipeline, especially the newly installed pipeline, the sediment, sundries, etc. Deposited in the pipeline, these sundries pose a serious safety hazard to the valve after the water is passed through. These sundries will accumulate at the bottom of the valve through the washing of water. If it is small, it will cause abrasion and d...
