Abstract

The utility model discloses a hot water facility, in particular to an auto decompression water heater that can supply water in a multi-channel way. The utility model is characterized in that a connecting pipe 7 is arranged between a hot water pipe 2 and a water complement pipe 3; a one-way valve 8 is arranged on the connecting pipe and is reverse to a one-way valve 5; a water complement valve 4 is arranged on the water pipe between the connecting point of the connecting pipe 7 and the water complement pipe 3 and the one-way valve 5; when heated, the water in a water tank 1 passes through the connecting pipe 7 and overflows to a water supply pipe along the water complement pipe 3, thereby reducing the pressure in water tank, playing a role of reducing pressure automatically, removing the water leakage phenomenon of heater, and avoiding wasting of water resource.

Description

A kind of automatic decompression multichannel water supply water heater

The utility model relates to a kind of hot water facility, especially a kind of multichannel water supply water heater that can reduce pressure automatically.

Water system in the present multichannel water supply hot water facility used in everyday mainly is made up of water tank, hot-water line, filling pipe and water compensating valve thereof, check valve and safety valve, when water is heated, because of the thermal expansion that adds of water causes the water tank internal pressure to increase, when pressure surpassed critical value, water will overflow from safety valve with decompression.Such design not only causes the waste at water source, and has brought the noise that leaks, leakage area below can not place worries such as thing.

The purpose of this utility model is, a kind of multichannel water supply water heater that can reduce pressure automatically is provided, and water can not be leaked when heating, avoids water waste.

The purpose of this utility model is achieved by the following technical programs.This automatic decompression multichannel water supply water heater, mainly form by water tank 1, hot-water line 2, filling pipe 3, water compensating valve 4, check valve 5 and safety valve 6, be characterized in, between its hot-water line 2 and filling pipe 3, also be provided with tube connector 7, the check valve 8 reverse with check valve 5 is housed on this tube connector, and water compensating valve 4 is installed on the tie point and the water pipe between the check valve 5 of tube connector 7 and filling pipe 3.

The utility model is after adopting such scheme, after water is heated, when the water tank internal pressure surpasses the pressure of supply water of running water, water in the water tank can be by the check valve of tube connector between hot-water line and the filling pipe, flow to running water pipe along filling pipe, so can outwards not leak, avoid the waste at water source, eliminate the noise that brings to people because of leaking, easily drench worry such as other article.

The explanation of accompanying drawing drawing:

The structural representation of an embodiment of Fig. 1-the utility model.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, further specify technical solution.

Embodiment is with reference to figure 1.Present embodiment is a domestic electric heating shower, mainly is made up of water tank 1, hot-water line 2, filling pipe 3, water compensating valve 4, check valve 5 and safety valve 6.Between its hot-water line 2 and filling pipe 3, have to be connected a tube connector 7, the check valve 8 reverse with check valve 5 is housed on this tube connector.Water compensating valve 4 is installed on the tie point and the water pipe between the check valve 5 of tube connector 7 and filling pipe 3.When water was heated, water tank 1 pressure inside can increase, and pressure will act on check valve 7 because hot water valve is closed the shutoff with check valve 5 this moment.When water tank 1 internal pressure during greater than the hydraulic pressure of running water, the water in the water tank will be discharged to running water pipe through filling pipe 3 along tube connector 7 and by check valve 8, thereby alleviates the pressure in the water tank, and therefore makes the inner normal pressure that keeps of water tank.When opening 4 pairs of water tank 1 water fillings of water compensating valve or shower, because of the unidirectional plugging action of check valve 8, running water can directly not flow to hot-water line 2 through check valve 8, and can inject water tank by check valve 5 and filling pipe 3.When cutting off the water, because the hot-water line delivery port in the water-heater water tank is positioned at the peak of water tank, the water in the water tank can be along check valve 8 running water pipe that flows backwards back yet.In addition, the reason that the design keeps safety valve 6 is, after the running water main valve cut out, because water tank 1 is by complete closed, when heating, water also will overflow to alleviate water tank 1 internal pressure by safety valve 6.

Claims

1, a kind of automatic decompression multichannel water supply water heater, mainly form by water tank (1), hot-water line (2), filling pipe (3), water compensating valve (4), check valve (5) and safety valve (6), it is characterized in that: between hot-water line (2) and filling pipe (3), be provided with tube connector (7), be equipped with on this tube connector and the reverse check valve (8) of check valve (5), water compensating valve (4) is installed on the tie point and the water pipe between the check valve (5) of tube connector (6) and filling pipe (3).
