Temperature controlling valve with function of cleaning valve core

Abstract

The invention discloses a temperature controlling valve with a function of cleaning a valve core, and belongs to the technical field of heating valves. The temperature controlling valve is characterized by consisting of a valve body, the valve core and a temperature controlling head, wherein the outer edge of the lower part of the valve core is connected with the valve body through screw threads; and the temperature controlling head is connected with the valve core through a connecting nut. When a valve works normally, the temperature controlling valve can effectively control the indoor temperature; and when the valve is blocked by impurities in a medium, the valve core can be detached for cleaning under the condition that the system is normally heated.

Description

technical field [0001] A temperature control valve with the function of cleaning a valve core belongs to the technical field of heating valves. Background technique [0002] With the gradual implementation of welfare heating policy reform, various temperature control valves at home and abroad have also appeared one after another. In the prior art, the structure of the valve body adopts a traditional model, which is composed of a valve body, a valve core, and a valve cap. The opening and closing of the temperature control valve is to use the temperature sensor installed on the outside of the valve to directly push the valve core. The temperature sensor senses the ambient temperature in the air, while the spool controls the flow of media in the valve. Since it does not have the sewage discharge function, after a long period of operation, various impurities in the heat medium will block the valve core, making it difficult to open and close the valve and failure of temperature...

AI Technical Summary

Problems solved by technology

Due to the lack of sewage discharge function, after a long period of operation, various impurities in the heat medium will block the valve core, resulting in difficulty in opening and closing the valve and failure of temperature control.

When such problems occur, the only solution is to close the water inlet and return valves of the indoor heating, and then replace the clogged valve with a new temperature control valve. Since disassembly is very inconvenient, the disassembled valve is generally It can no longer be used, causing waste. Since the existing technology cannot be cleaned online, many temperature control valves cannot work normally after being used for a period of time.
