According to design provided by the utility model, expansion tank is connected into the casing of a sealing by air pressure side cover plate and hydraulic pressure side cover plate, the diaphragm of rubber that cabinets cavity can be divided into two parts is arranged in casing, on the air pressure side cover plate, inflation inlet is set, on the hydraulic pressure side cover plate, water inlet is set, it is characterized in that: the connecting portion at air pressure side cover plate and hydraulic pressure side cover plate is provided with the connecting band that the cross section is the U type, one lateral edges of this connecting band is directly formed by the edge of hydraulic pressure side cover plate, the opposite side edge is pressed on the edge of air pressure side cover plate, and the edge clamping of diaphragm of rubber is between the edge of the edge of air pressure side cover plate and hydraulic pressure side cover plate.
Another kind of expansion tank is connected into the casing of a sealing equally by air pressure side cover plate and hydraulic pressure side cover plate, the diaphragm of rubber that cabinets cavity can be divided into two parts is arranged in casing, on the air pressure side cover plate, inflation inlet is set, on the hydraulic pressure side cover plate, water inlet is set, it is characterized in that: the connecting portion at air pressure side cover plate and hydraulic pressure side cover plate is provided with the connecting band that the cross section is the U type, but a lateral edges of this connecting band is directly formed by the edge of air pressure side cover plate, the opposite side edge is pressed on the edge of hydraulic pressure side cover plate, and the edge clamping of diaphragm of rubber is between the edge of the edge of air pressure side cover plate and hydraulic pressure side cover plate.
The side mounting bracket of air pressure side cover plate or hydraulic pressure side cover plate.
The utility model has the advantages that: abandoned clip fastening-type structure in the past, adopt more reliable structure, air pressure side cover plate 1 and hydraulic pressure side cover plate 2 and inner lining every diaphragm of rubber 3, use the mould punching press, make one limit of its hydraulic pressure side cover plate 2 firmly embrace air pressure side cover plate 1 and diaphragm of rubber 3, reduced the not seal of expansion tank casing as much as possible, and the effective expanded service life of energy, and this product air pressure side inflation inlet 5 is for the common valve inside that is usually used on the bicycle is riveted on the air pressure side cover plate 1, makes the air pressure side charge and discharge gas and safeguards more convenient.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in Figure 1: expansion tank is connected into the casing of a sealing by air pressure side cover plate 1 and hydraulic pressure side cover plate 2, the diaphragm of rubber 3 that cabinets cavity can be divided into two parts is arranged in casing, inflation inlet 5 is set on air pressure side cover plate 1, water inlet 6 is set on hydraulic pressure side cover plate 2, connecting portion at air pressure side cover plate 1 and hydraulic pressure side cover plate 2 is provided with the connecting band 7 that the cross section is the U type, one lateral edges of this connecting band 7 is directly formed by the edge of hydraulic pressure side cover plate 2, the opposite side edge is pressed on the edge of air pressure side cover plate 1, and the edge of diaphragm of rubber 3 is sandwiched between the edge of the edge of air pressure side cover plate 1 and hydraulic pressure side cover plate 2.Side mounting bracket 4 at air pressure side cover plate 1 or hydraulic pressure side cover plate 2.
Air pressure side cover plate 1 wherein is in order to the storage air and guarantee that the air pressure side has certain pressure.Hydraulic pressure side cover plate 2 shifts the pressure of a part to burning water tank and water pipe in order to bear the volume that expands in water heating back.Diaphragm of rubber 3 because it adopts rubber raw materials to make, so have stronger elasticity, when the hydraulic pressure lateral pressure returns to normal value, is discharged water tank with the water of transferring to the hydraulic pressure side in order to air pressure side and hydraulic pressure side are separated.Prop up part 4 in order to this water tank and other parts are installed and fixed together.Inflation inlet 5 is in order to charge into the air of certain pressure to the air pressure side, inflation inlet adopts rubber-tyred inflation inlet commonly used, uses more convenient.Water inlet 6 is in order to be connected with the burning radiator drain, and it adopts the design of general gas thread, and sealing is better, is connected and installed conveniently.
As another kind of embodiment, a lateral edges of connecting band 7 is directly formed by the edge of air pressure side cover plate 1, the opposite side edge is pressed on the edge of hydraulic pressure side cover plate 2, and all the other structures are all same as described above.Two kinds of form effects are basic identical.
The pressure of balance water heater heating water tank and water pipe when this product is mainly used in the water heater heating.For making product reach designing requirement, casing adopts air pressure side cover plate 1 and hydraulic pressure side cover plate 2 respectively by unitary mould stretch forming, then at air pressure side cover plate 1 and hydraulic pressure side cover plate 2 middle lining diaphragm of rubber 3, use the technology of a punching press pressing of mould again, make it form the cell of two complete airtight isolation, wherein 3 of air pressure side cover plate 1 and diaphragm of rubber form air pressure side cell, charge and discharge gas by the inflation inlet on the air pressure side cover plate 15; 3 of hydraulic pressure side cover plate 2 and diaphragm of rubber form hydraulic pressure side cell, are connected to water heater pipeline by the pipe joint on the water inlet 6, and diaphragm of rubber 3 adopts elasticity strong and can make by high temperature resistant elastomeric material, guarantees to bear bigger pressure.
The operation principle of this product is, by the pipe joint on the water inlet 6, expansion tank is connected in the water heater outlet pipeline system, in air pressure side cell, charge into the air of certain pressure in advance, work as the water heater heating during work, water temperature raises, when water volume expands, the pressure of hydraulic pressure side cell is greater than the pressure of air pressure side cell, the part water that expands is just oppressed diaphragm of rubber 3, from the connector of water heater outlet and expansion tank, transfers to expansion tank, reduce the pressure of water heater heating water tank and pipeline, when water temperature reduction pressure returned to normal value, owing to have the certain pressure air in the air pressure side cell, diaphragm of rubber 3 had very strong elasticity again, can discharge expansion tank to the water of transferring in the hydraulic pressure side cell, thereby well play the effect of pressure transfer balance, reach the designing requirement of product, fully satisfy serviceability.
