Abstract

The utility model discloses a multifunctional gas heating water heater valve which comprises a pressure relief valve, a water supplementing valve and a water supplementing pipe. A water pump connector, a water pressure switch connector, a water pressure detection connector, an expansion tank connector, a water supplementing connector and a pressure relief connector. A water pump and a water pressure switch are respectively placed on the water pump connector and the water pressure switch connector; the water pressure detection connector is connected with a water pressure gauge through a water pressure connecting pipe; an expansion water tank connector is connected with the expansion water tank through a water tank pipe; and a water inlet, a water outlet connected with the water supplementing pipe and a switch connector used for installing a water supplementing switch are formed in the water supplementing valve. The water supplementing valve and the pressure relief valve are respectively separated and then are connected through the water supplementing pipe, and therefore when the water supplementing valve and the pressure relieve valve are produced, copper materials can be greatly saved, the structure and manufacturing process of the whole functional valve become simple and production cost is reduced. When being damaged, one functional component can be independently replaced rather than the whole functional valve is replaced, and therefore the multifunctional gas heating water heater valve is convenient to maintain and reduced in maintenance cost.

Description

Gas-heating water heater multifunction valve

[technical field]

The utility model relates to a kind of wall hanging stove, refers in particular to the multifunction valve that is installed in the wall hanging stove.

[background technology]

We know, the security of gas-heating water heater is vital, be provided with structures such as hydraulic pressure detection, hydraulic pressure gauge tap, moisturizing, pressure release adjusting, expansion tank within it, these structures of current wall hanging stove all are integrated into and connect in the valve body or realize, for this reason, the necessary volume ratio of copper valve body of making this multifunction valve is bigger, and material is many, and the duty valve cost is higher, manufacturing process is complicated thereby bring; And, owing to be the integral type valve body, in case certain functor damage, just must whole replacing, and cumbersome when dismounting, be not easy to maintenance; Meanwhile, the situation of leaking, maintenance rate height appear in each assembly easily in the junction.

[utility model content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, and a kind of simple in structure, easy to maintenance and gas-heating water heater multifunction valve that maintenance cost is low is provided.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of gas-heating water heater multifunction valve includes relief valve, water compensating valve and is connected filling pipe between them, wherein:

Valve body at described relief valve is provided with water pump interface, hydraulic pressure switch interface, hydraulic pressure detection interface, expansion tank interface, repaired mouth interface and pressure relief opening, be separately installed with water pump and hydraulic pressure switch at described water pump interface and hydraulic pressure switch interface, described hydraulic pressure detects interface and is connected with water pressure gauge through the hydraulic pressure tube connector, and described expansion tank interface is connected with expansion tank through cistern tube;

Valve body at described water compensating valve is provided with water inlet, the delivery port that is connected with filling pipe that is connected with external moisturizing source and the switch interface that is used for installing the moisturizing switch;

Described filling pipe two ends are provided with nut type adapter sleeve structure.

Compared with prior art, the beneficial effects of the utility model are: because it is that water compensating valve and relief valve are independently opened respectively, couple together by filling pipe again, like this when producing the copper valve body of water compensating valve and relief valve, can save copper material greatly, also make structure and the manufacturing process of whole functional valve become fairly simple, thereby reduce production costs; When functional part in certain damages, just can change separately targetedly, and need not resemble the whole functional valve replacement to be fallen present stage, make of the present utility model easy to maintenance, maintenance cost is low.

Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:

[description of drawings]

Fig. 1 is the connection diagram of the utility model embodiment;

Fig. 2 is the dismounting schematic diagram of the utility model embodiment;

Fig. 3 is the relief valve valve body schematic perspective view of the utility model embodiment.

[specific embodiment]

The utility model is a kind of gas-heating water heater multifunction valve, includes relief valve 1, water compensating valve 2 and is connected filling pipe 3 between them, wherein:

Valve body 11 at described relief valve 1 is provided with and water pump interface 111, hydraulic pressure switch interface 112, hydraulic pressure detection interface 113, expansion tank interface 114, be separately installed with water pump 4 and hydraulic pressure switch 5 at described water pump interface 111 and hydraulic pressure switch interface 112, described hydraulic pressure detects interface 113 and is connected with water pressure gauge 7 through hydraulic pressure tube connector 6, and described expansion tank interface 114 is connected with expansion tank 9 through cistern tube 8;

Valve body 21 at described water compensating valve 2 is provided with water inlet 211, the delivery port 212 that is connected with filling pipe 3 that is connected with external moisturizing source and the switch interface 213 that is used for installing moisturizing switch 50;

Described filling pipe 3 two ends are provided with nut type adapter sleeve structure 60, and adapter sleeve structure 60 is tightened or when unscrewing the interface at place, filling pipe 3 can and then not rotate turning like this.

The utility model is installed to when using on the wall hanging stove, when detecting hydraulic pressure, water pressure gauge 7 is lower than when setting value, moisturizing switch 50 is opened water compensating valve 2, the water inlet 211 of water compensating valve valve body 21 flows to the water that comes and enters in the relief valve 1 from delivery port 212 filling pipe 3 of flowing through like this, realizes replenishing wall hanging stove cycling use of water.Because the operation principle of hydraulic pressure detection, expansion tank and the pressure release of duty valve is with current the same substantially, detailed description no longer hereinto.

The utility model is that water compensating valve and relief valve are independently opened respectively, couple together by filling pipe again, when producing the copper valve body of water compensating valve and relief valve, can save copper material greatly like this, also make structure and the manufacturing process of whole functional valve become fairly simple, thereby reduce production costs; When functional part in certain damages, just can change separately targetedly, and need not resemble the whole functional valve replacement to be fallen present stage, make of the present utility model easy to maintenance, maintenance cost is low.

Although describe the utility model in detail with reference to top embodiment, but it will be apparent to one skilled in the art that by the disclosure, and under the situation of the principle of the present utility model that does not break away from described claim restriction and spiritual scope, can make a variety of changes or revise the utility model.Therefore, the detailed description of disclosure embodiment only is used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
