Combined type air feeding and exhausting valve of waterproof hammer structure

Abstract

The invention provides a combined type air feeding and exhausting valve of a waterproof hammer structure. The combined type air feeding and exhausting valve comprises a valve body and a valve cover located on the valve body, wherein a water inlet is formed in the bottom of the valve body; the valve body is internally provided with an upper cavity and a lower cavity; the upper cavity is a main airfeeding and exhausting cavity and the lower cavity is a buffering cavity; the upper cavity is internally provided with a floating ball capable of moving up and down; a guide part is arranged at the top of the floating ball; the guide part is connected with a guide hole in the valve cover; a tray is arranged on a valve body at the bottom of the upper cavity; a connecting pipe is arranged in the lower cavity; a waterproof hammer valve clack sleeves the connecting pipe; the upper end of the connecting pipe is connected with a part located between the upper cavity and the lower cavity of the valvebody. According to the combined type air feeding and exhausting valve of the waterproof hammer structure, provided by the invention, the waterproof hammer valve clack is additionally arranged at thebottom of the exhausting valve; the strength of bridging of water hammer can be greatly reduced and damages to a pipeline are avoided.

Description

Technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a composite inlet and outlet valve with a waterproof hammer structure. Background technique [0002] The composite inlet and outlet valve is an industrial equipment that discharges the gas in the pipeline and inhales the gas into the pipeline, and is one of the important equipment to protect the pipeline. When the pipeline connected to the composite intake and exhaust valve is emptied, the valve will take in a large amount of air, and then when the emptied pipeline is watered again, the front and back fluids in the pipeline will form a bridging water hammer, which will cause great damage to the pipeline. Therefore, it is necessary to develop and design a composite intake and exhaust valve that can greatly reduce the strength of this kind of water hammer. Summary of the invention [0003] In view of this, the present invention aims to propose a composite inlet and exhaust va...

AI Technical Summary

Problems solved by technology

When the pipeline connected to the composite intake and exhaust valve is emptied, the valve will inhale a large amount of air, and then when the emptied pipeline is passed through again, the front and rear fluids in the pipeline will form a bridging water hammer, which will cause great damage to the pipeline.
