Abstract
The utility model relates to a sealing device for an end opening of a plastic hot water tank of an electric water heater. In the utility model, the outside of an end opening is matched with a hollow pushing and pressing cap by threads, and a small step ring is made inside the end opening. The utility model is characterized in that a sealing washer is placed on the step ring, and a metal cover plate of a disc is arranged below the washer; a sealing compressing ring whose height is higher than the height of the end opening is arranged between the edge of the metal cover plate and the pushing and pressing cap. The utility model has the advantages of convenient fabrication, good sealing performance, and convenient installation and disassembly.
Description
The utility model relates to a kind of port sealing device of plastic hot water tank of electric heater.It belongs to plastic hot water receptacle port sealing device.
The boiler of electric heater adopts metallic plate to be made more now, and its advantage is easy to manufacture, and port seals well, and weak point is, cost is higher, and water easily fouling within it, and easy again blocking pipeline of dirty thing and valve body are made troubles to the user.If adopt the boiler of plastic production, can reduce cost first, second can prevent the fouling of sealing, be to kill two birds with one stone, still, because the duty of this boiler is an inversion type, must electric heater be put in the boiler from the port again, so its port sealing then is a difficult problem.
The purpose of this utility model is to provide a kind of port sealing device of plastic hot water tank of electric heater, and it is good that the sealing device has the tight performance of sealing, and dismounting makes things convenient for characteristics by dress.
In order to achieve the above object, the utility model is realized by following proposal.The port of plastic hot water tank is the column type that reducing enlarges shape, form a small stair ring within it, the outer surface of port is shaped on screw buckle, and prepare hollow roof pressure cap, it is characterized in that, on the step ring, place a seal washer, place the metal cover board of a disc shape under the seal washer, between the edge of metal cover board and hollow roof pressure cap, a sealing hold-down ring that highly is higher than port is set.
Accompanying drawing is a structural representation of the present utility model.Wherein 1 is hollow roof pressure cap, and 2 is the port of plastic hot water tank, and 3 are the sealing hold-down ring, and 4 is the disc metal cover board, and 5 is seal washer.
The utility model realizes that the port sealing process is as follows: seal washer is placed on the step anchor ring in the port, adds and cover the disc metal cover board, put the sealing hold-down ring then, at last hollow roof pressure cap is tightened.So the thrust of pressure cap passes to disc metal cover board edge and seal washer by the sealing hold-down ring, behind their pressurizeds, metal cover board edge and seal washer have fully been guaranteed, and fitting tightly between the three of sealing ring and step anchor ring, thereby realized the purpose of the port sealing of plastic hot water tank.
The utility model is simple in structure, make easily, and sealing property is good, and dismounting is convenient by dress.
