Embodiment Construction
[0020] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0021] The embodiment of the present invention provides a full-composite material airbag-type pressure tank. The airbag 5 and the shell in the pressure tank are all made of composite materials, and are mainly used in central air conditioners, boilers, water heaters, frequency conversion, and constant pressure water supply equipment. , its function is to buffer the pressure fluctuation of the system, eliminate the water hammer, play the role of stabilizing the unloading and replenishing a small amount of water at night.

The invention discloses an all-composite material air bag type pressure tank and a manufacturing method thereof, and aims to achieve pressure resistance and corrosion resistance, solve the problems that a shell is prone to corrode, an air bag is prone to damage and the service life is short, and is simple in manufacturing process. The pressure tank comprises the shell and the air bag arranged in the shell, wherein the shell comprises a lining and glass fibers arranged on the outer side of the lining in a winding mode, the lining is made of a PE material, the lining is provided with a first connecting port and a second connecting port, the air bag is located in an inner cavity of the lining, the air bag and the inner wall of the lining are arranged in a spaced mode, the air bag is made of a polyurethane material, the air bag is integrally formed and connected with an air nozzle in a communicating mode, the air nozzle is inserted and fixed to the first connecting port in a sealed mode, the second connecting port is fixedly connected with an elbow, the first end of the elbow is communicated with an inner cavity of the lining through the second connecting port, and the second end of the elbow is communicated to a pipeline.
Description
technical field [0001] The invention relates to the technical field of an airbag pressure tank, in particular to an all-composite material airbag pressure tank and a manufacturing method thereof. Background technique [0002] In the prior art, the airbag pressure tank mainly uses a steel shell as the main body, with a built-in rubber airbag. According to Bohr's law PV=C, when the gas is compressed, the volume becomes smaller and the pressure rises until the gas pressure in the pressure tank is equal to the water pressure. When the consistency is reached, stop the water intake. When the water loss pressure decreases, the gas pressure in the pressure tank is greater than the water pressure. At this time, the gas expands and squeezes out the water in the airbag pressure tank to fill the system until the gas pressure and water pressure reach a consensus. stop draining. It is mainly used for system pressure fluctuation and partial water supply. The disadvantage of this airbag t...
