Built-in bypass valve body applicable for control of water channels in wall hanging stove system

Abstract

The invention discloses a built-in bypass valve body applicable for control of water channels in a wall hanging stove system. The built-in bypass valve body comprises a shell and a bypass mechanism; the shell is provided with a water inlet channel, a first water outlet channel, a second water outlet channel and a bypass mechanism storage cavity; and the first water outlet channel and the second water outlet channel communicate with the water inlet channel in a switching manner separately. According to the built-in bypass valve body disclosed by the invention, the technical problem that the built-in bypass valve body applicable for the control of the water channels in the wall hanging stove system is hard to manufacture is solved.

Description

technical field [0001] The present invention relates to a water outlet module in a wall-hung boiler system, specifically a water outlet module that is applied to the above-mentioned water outlet module to bypass the water in the heating water outlet to the interior of the bathroom heat exchanger when special circumstances occur and is applied to the wall-hung boiler. Built-in bypass valve body for waterway control in the system. Background technique [0002] The waterway module or waterway integration is a key component in the internal waterway system of the wall-hung boiler. Its function is to integrate the circulation pipelines into one body, and integrate functions such as waterway switching, water replenishment, and sanitary water flow detection. The waterway module is generally equipped with various interfaces such as a circulating water pump, a safety valve, a temperature sensor, a pressure sensor, and an expansion tank. The principle of the waterway module is: please...

AI Technical Summary

Problems solved by technology

The existing waterway bypass modules usually adopt the method of adding bypass pipes externally, which not only greatly increases the manufacturing cost of the waterway module, but also increases the conditions for external leakage

[0003] Chinese patent application number 201220347681.5 discloses an independent built-in waterway bypass module, which has a water inlet and two water outlets and also has a bypass valve, and one of the water outlets is connected to radiators and other equipment, which is called here The first water outlet channel and the other water outlet channel are connected to the plate heat exchanger, which is called the second water outlet channel here; the bypass valve is connected between the water inlet end of the main exchange cycle hot water and the water outlet end that communicates with the plate heat exchanger , the water outlet below the hot water inlet of the main exchange cycle is also called the heating end. This heating end is mainly connected with radiators, etc. When it no longer flows and the heating end is heated, the water in the heating end will expand due to heat, so that the motor directly above the heating end cannot open the valve located in the heating end, that is, it cannot drive the valve to move downward so that the water pressure at the heating end Leading out from the bypass valve, this creates a greater safety hazard; at the same time, the design of the above-mentioned bypass valve is mainly to be attached to the wall, that is, on the same side as the plate heat exchanger. When maintenance is required, the entire waterway module needs to be Take it off, which will bring more inconvenience to maintenance and installation

[0004] The current built-in bypass valve body used in the waterway control of the wall-hung boiler system generally uses copper parts, and its manufacturing and assembly costs are relatively high. In addition, the current bypass valve structure can not play a good sealing effect
