Description

A control valve with leakage alarm function

Technical field

The utility model relates to the field of control valves, in particular to a control valve with a leakage alarm function.

Background technique

Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves are the most important components in fluid delivery systems. The control component has the functions of cutting off, regulating, diverting, preventing reverse flow, stabilizing voltage, diverting or overflowing and reducing pressure. During the use of the control valve, leakage may easily occur at its connection with the pipeline.

The existing application number is CN201920581698.9, a valve with a leakage alarm function. Although it is fixedly connected with a first connection box and a second connection box through the outer surfaces of the first clamp and the second clamp, the second connection box is fixedly connected to the valve. The first connection box and the second connection box are spliced and fitted. When the valve body leaks, the leaked liquid will enter the detection box through the hose and be electrically connected to the external alarm device through the water immersion sensor in the detection box, thereby making The water immersion sensor senses the presence of liquid and sends out a signal, causing the alarm device to alarm. It achieves the purpose of leak alarm and avoids waste of resources. However, its structure is relatively complex and is not conducive to popularization and use. At the same time, the distance between the water immersion sensor and the leakage point is Far away, the liquid leaking from the leak point needs to reach a certain amount and takes a long time to flow to the water immersion sensor, resulting in poor timeliness of the leak alarm, so it needs to be improved.
