Thermostat valve plug

Abstract

The invention discloses a thermostat valve plug. The thermostat valve plug comprises a shell part which is provided with cold and hot water inlet passages and a mixed water outlet passage, and a water outlet valve seat and a regulation assembly which are arranged and positioned in the shell part. A turning member of the regulation assembly is controlled to drive a water outlet valve to move up and down to be sealed with the water outlet valve seat in a pressed way or separated from the water outlet valve seat, so that a water outlet valve port of mixed water can be opened or closed; a temperature sensing element is driven by the water outlet valve which moves downward to push a water inlet valve to move downward, so that a hot water inlet valve port is closed or reduced; and when the water outlet valve moves upward, an elastic recovery element pushes the water inlet valve to move upward so as to close or reduce a cold water inlet valve port. The temperature sensing element cam sense the temperature of the mixed water and is extended or pressed and shortened so as to automatically adjust the sizes of the cold and hot water inlet valve ports, and ensure that the mixed water is kept in a constant temperature state. The water outlet control and constant temperature keeping functions are realized by a single turning member.

Description

technical field [0001] The invention relates to a water outlet device, specifically, a temperature-controlled valve core that can use a single rotary member to achieve dual functions of water outlet opening and closing and temperature regulation and control, and has a constant temperature maintenance function. Background technique [0002] Existing hot and cold fluids, especially the mixing valve element of hot and cold water, often cannot flow out the mixed water at a stable temperature due to pressure and / or temperature changes of the cold and hot water. Based on the above reasons, it has been widely disclosed in many technical documents to assemble thermal sensitive elements in these mixing valve core assemblies to automatically adjust the temperature of the mixed water so as to keep the mixed water at a certain constant temperature state as much as possible. [0003] In the above-mentioned technical documents, such as the invention patent of the United States Publication...

AI Technical Summary

Problems solved by technology

The above-mentioned temperature rotary member may also be set at a temperature position that is too high or too low. Therefore, when the user turns on the flow rate rotary member and uses the mixed fluid before adjusting the temperature, it is easy to cause burns or frostbite.

In some cases, such as different occasions, users or fluid usage methods, do not care about the flow rate of the mixed fluid, but attach great importance to the temperature. In this case, it may only be used as an opening and closing member of the mixed fluid. , but cannot demonstrate its flow regulation function, and is even regarded as an obstacle in the operation process, so that there is a need for further improvement
