Temperature and pressure reduction regulating valve

Abstract

The invention discloses a temperature and pressure reduction regulating valve which comprises a regulating valve body. A water inlet pipe is fixedly installed on the outer surface of one side of the regulating valve body, a connecting valve is fixedly installed on the outer surface of the side, close to the regulating valve body, of the water inlet pipe, and the water inlet pipe and the regulating valve body are fixedly installed through the connecting valve; and a valve hole is formed in the side, close to the connecting valve, of the outer surface of the water inlet pipe, a cleaning valve is movably installed in the valve hole, a movable rod is movably installed in the lower end of the cleaning valve, and a cleaning piece is fixedly installed on the outer surface of the movable rod. According to the device, dirt in a pipeline can be filtered, the situation that the dirt enters the regulating valve to damage the regulating valve is avoided, the service life of the device is prolonged, meanwhile, the filtered dirt can be cleaned and discharged, the device does not need to be disassembled, the cleaning mode is simple, rapid and efficient, and the using effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of regulating valves, in particular to a temperature reducing and pressure reducing regulating valve. Background technique [0002] The temperature reduction and pressure reducing regulating valve uses the opening degree of the opening and closing parts in the valve body to adjust the flow of the medium to reduce the pressure of the medium. Within a certain range, cooling water is sprayed into the valve body or behind the valve to reduce the temperature. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been resolved: [0004] 1. After long-term use of the connecting pipe of the regulating valve, dirt such as rust and welding slag will appear. After these dirt enters the interior of the regulating valve, it will cause wear to the valve core and valve seat of the regulating valve and affect the normal operation of the...

AI Technical Summary

Problems solved by technology

[0004] 1. After long-term use of the connecting pipe of the regulating valve, dirt such as rust and welding slag will appear. After these dirt enters the interior of the regulating valve, it will cause wear to the valve core and valve seat of the regulating valve, affecting the normal operation of the regulating valve , the traditional regulating valve does not have a structure to filter the dirt inside the pipeline, and often can only filter the water before entering the pipeline, but cannot filter the dirt inside the pipeline;

[0005] 2. After filtering the dirt, it is necessary to discharge the filtered dirt in time, so as to prevent the dirt from adhering to the filter screen and blocking the holes of the filter screen, resulting in blockage of the pipeline and making the device unable to operate normally
