Abstract
The utility model relates to an interstage valve for a gas water heater, which comprises a valve body of the interstage valve, a diaphragm, a water valve, a small linking shaft, a sealing member, a water service pipe and a dividing piece. Because the utility model adopts the structure that the dividing piece is arranged between the diaphragm and the valve body of the interstage valve, the corrosion problem of the valve body of the interstage valve is solved under the condition of assuring the using function of the valve body of the interstage valve, so water entering from the water service pipe is ensured to be only in a cavity body composed of the dividing piece, the diaphragm and the sealing member, the water and the valve body of the interstage valve are completely divided, and thus the contact of the valve body of the interstage valve and the water is avoided. The safe using property of a water heater is not only ensured by the utility model, but also the production cost of the water heater is reduced. The utility model is a novel interstage valve with a dividing piece for a gas water heater and has the advantages of simple structure, convenience and practicability.
Description
The utility model is a kind of interstage valve that is used for gas heater, belongs to the renovation technique of the used interstage valve of gas heater.
The structure that the used interstage valve of existing gas heater all adopts the water valve valve pocket to communicate with the interstage valve valve pocket, because the interstage valve valve body directly contacts with water, so the interstage valve valve body is easily by corrosion, therefore directly influence the safe handling of water heater, for this reason, some producer is the safe handling of guaranteeing water heater, and its interstage valve valve body has to adopt the more expensive corrosion resistant material of price to be made, but this has increased the production cost of water heater again, thereby has increased producer and consumer's burden.
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of band partition interstage valve of avoiding the interstage valve valve body to contact with water is provided, it has not only solved the corrosion problem of interstage valve valve body, thereby guaranteed the safe handling of water heater, and reduced the production cost of water heater.
Structural representation of the present utility model as shown in drawings, include interstage valve valve body (1), barrier film (2), water valve (3), little axle (4) links, seal (5), water service pipe (6), its septation (2) places between interstage valve valve body (1) and the water valve (3), the end of little axle (4) of linking is bearing on the interstage valve valve body (1) by seal (5), and by seal (5) sealing, the other end places the side of barrier film (2), the delivery port of water service pipe (6) places in the cavity between interstage valve valve body (1) and the barrier film (2), delivery port is connected with peripheral water pipe, is provided with the partition (7) of avoiding water to contact with interstage valve valve body (1) on the position between barrier film (2) and the interstage valve valve body (1).
Describe concrete structure of the present utility model in detail below in conjunction with embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include interstage valve valve body (1), barrier film (2), water valve (3), little axle (4) links, seal (5), water service pipe (6), its septation (2) places between interstage valve valve body (1) and the water valve (3), the end of little axle (4) of linking is bearing on the interstage valve valve body (1) by seal (5), and by seal (5) sealing, the other end places the side of barrier film (2), the delivery port of water service pipe (6) places in the cavity between interstage valve valve body (1) and the barrier film (2), delivery port is connected with peripheral water pipe, and barrier film (2) is provided with the partition (7) of avoiding interstage valve valve body (1) to contact with water with position between the interstage valve valve body (1).Seal (5) includes threaded connector (51) and sealing ring (52,53), the little axle (4) that links is set on the through hole A of threaded connector (51), threaded connector (51) is connected with interstage valve valve body (1) by screw thread, and sealing ring (52,53) places respectively on the contact-making surface of the contact-making surface of the little axle of interlock (4) and through hole A and threaded connector (51) and partition (7).The available stainless steel of above-mentioned partition (7) is made, and also the available copper material is made.In the present embodiment, partition (7) is made with stainless steel.The available general material of interstage valve valve body (1) is made, and does not need to make with Cu alloy material.
The utility model in use, water is entered in the cavity B that partition (7) and barrier film (2) and seal (5) formed by water service pipe (6), because the pressure of the cavity B on barrier film (2) both sides and the inner chamber C of water valve (3) changes, therefore produce pressure reduction and promote the little axle of interlock (4) motion, control the break-make of water heater microswitch thus, work reliably with automatic assurance water heater safety.
The utility model is owing to adopted the structure that is provided with partition between barrier film and interstage valve valve body, therefore guaranteeing under its situation of using function, not only solved the corrosion problem of interstage valve valve body, thereby guaranteed that the water that is entered by water service pipe can only be in the cavity that partition and barrier film and seal are formed, separate fully with the interstage valve valve body, thereby avoided the interstage valve valve body to contact with water, so the utility model has not only guaranteed the safe application performance of water heater, and has reduced the production cost of water heater.The utility model is a kind of simple in structure, convenient and practical, the novel band partition interstage valve that is used for gas heater with low cost.
