Abstract

The utility model relates to a function expanding device for a gaseous fuel combustion water heater, which is integrated by a plurality of differential valves, and the differential valves are individually controllable. The main aim of the utility model is to extend the function of the gaseous fuel combustion water heater and implement the multiple purposes of the gaseous fuel combustion water heater. A 1 and A 2 in the accompanying diagram are water inlets, and the B 1 and B 2 are water outlets. C is connected with the water outlets of the gaseous fuel combustion water heater, D is connected with the water inlets of the gaseous fuel combustion water heater, and E is a respiratory port. When water gets into A1 firstly, water enters a chamber 1, then flows through a passage 3, and flows into the water heater through D. Because the active area of a diaphragm (2) is far larger than that of a valve plate (4), the pressure difference leads the valve plate (4) to move left through compressing a spring, C is led to be communicated with B 1, and the hot water of the gaseous fuel combustion water heater flows from B 1 to the water using place. In a similar way, if water gets into A 2 firstly, then hot water flows to the other water using place from B 2.

Description

The gas heater function expanding device

The utility model relates to a kind of by the integrated gas heater function expanding device of a plurality of independent control different valves.

Be to adopt the single control of single channel in the present gas heater technology, have only a water inlet, a delivery port.Water inlet and bathroom water inlet control valve join, and delivery port and shower join.Therefore, water heater only can use for shower, wants it with just very inconvenient, has limited the scope of application of gas heater.

The purpose of this utility model provides that a kind of simple in structure, handiness, cost are low, the gas heater function expanding device of reliable operation, so that realize how usefulnessization of gas heater easily.

The purpose of this utility model is achieved in that the entery and delivery port at existing gas heater connects one by the integrated gas heater function expanding device of the different valve of a plurality of independent controls.This function expanding device has a plurality of different valves.Each different valve all has a water inlet, a delivery port.The unlatching of delivery port is by intake pressure control automatically.These entery and delivery ports join with the water inlet control valve and the delivery port that use the hot water place respectively.When hot water need be used in the somewhere, only need turn on water inlet control valve herein, delivery port promptly has the hot water supply.

The import and export of the various model gas heaters that the utility model can be easily produced with the market different manufacturers link to each other, make the water heater function expansion, realize multiple use, the expansion scope of application.

The concrete structure of utility model is provided by following example and accompanying drawing thereof.

Fig. 1 and Fig. 2 are according to the gas heater function expanding device structure example that the utility model proposes.

Describe details and operation principle in detail below in conjunction with Fig. 1 Fig. 2 according to the instantiation that the utility model proposes.

This example mainly comprises a conglomerate (5), two identical different valves.Different valve is made up of valve body (4), valve gap (1), diaphragm (2), valve block (3), valve rod (6), spring (7), O RunddichtringO (8).The C, the D mouth that are connected with water heater are arranged on conglomerate (5).Valve gap has water inlet A on (1) ₁(A ₂), valve body has water outlet B on (4) ₁(B ₂) and pneumostome B.Water inlet A ₁(A ₂) communicate with the D mouth through the internal channel of valve body (4) and conglomerate (5).If A ₁Connect the bathroom water inlet control valve, then B ₁Connect shower.A ₂Connect kitchen wash basin water inlet control valve, B ₂Connect the kitchen wash basin.When need during to bathroom shower device heat supply water, only need turn on the bathroom water inlet control valve, running water is from A ₁Enter in valve gap (1) chamber,, enter water heater by D through valve body (4) internal channel.Because the active area of diaphragm (2) is much larger than valve block (3), its pressure differential compression spring (7) is pushed valve block (3) to move to left to through valve rod (6), makes C mouth and B ₁Mouth communicates, and the hot water of water heater is then from B ₁Flow to shower.In like manner, if open kitchen wash basin water intaking valve, running water is from A ₂Enter, then water heater hot-water is through B ₂Flow to the kitchen wash basin.For guaranteeing under low hydraulic pressure (0.025MPa) from the beginning, function expanding device energy reliably working, when implementing the utility model, under the condition that guarantees required water channel area and valve block (3) energy positiver sealing exhalant canal, dwindle the rigidity of the diameter and the reduction spring (7) of valve block (3) as far as possible.Sealing between valve rod (6) and the valve body (4) guarantees with O RunddichtringO (8).Seal with rubber blanket (9) between conglomerate (5) and valve body (4).

Last example is the two-way function expanding device of implementing by the utility model, as need three tunnel, four road function expanding devices, only needs to change conglomerate (5) into triangular prism or hexahedron can be integrated by annular is corresponding.

Claims

1, gas heater is extended to multiduty gas heater function expanding device from special purpose, this device forms by the different valve of a plurality of independent controls is integrated, it is characterized in that shape difference according to conglomerate (5), can integrated two, three or four different valves of control separately, form two-way, three road or four road function expanding devices, each different valve is to rely on to do to control one tunnel water outlet automatically in the pressure differential of diaphragm (2) and valve block (3).

2, device according to claim 1 is characterized in that the pressure differential control water outlet by diaphragm in the different valve (2) and valve block (3).When pressure disappears, diaphragm (2) reset and the sealing of valve block (3) is to rely on same spring (7) to guarantee.

3, device according to claim 1 is characterized in that the different valve water inlet A ₁Be to communicate with the C mouth, do not need to take in addition the road by the internal channel on differential valve gap (1), valve body (4), the conglomerate (5).
