Capsule pressure-stabilizing tank

Abstract

The invention provides a capsule pressure-stabilizing tank. The tank comprises a tank body and an inner bag arranged in the tank body. The top of the tank body is welded with an upper seal head and the bottom is welded with the lower seal head; the inner bag is used for separating the tank body into an air chamber and a water chamber; the bottom of the tank body is provided with a flange and the lower seal head for welding and fixing; and the middle of the flange plate is welded with a water inlet and outlet connecting pipe communicated with the water chamber, and the flange plate and the flange bolt are connected to realize sealing. The tank only provides a flange at the bottom, which has low cost and reduces the risk of leakage of the top flange with good sealing and no air leakage, which saves space. The tank is convenient fastening with low cost, which does not pollute water quality, and is convenient to charge and discharge; the tapered inner capsule can reduce the stress fatiguecaused by the pressure increase of the inner capsule and improve the service life of the inner capsule.

Description

technical field [0001] The invention belongs to the technical field of water supply equipment, and in particular relates to a bladder type pressure stabilizing tank. Background technique [0002] The surge tank is mainly used in thermal systems and water supply systems, such as air conditioners, boilers, heat pumps, water heaters and other thermal systems. It is used in conjunction with water pumps to save electricity and reduce energy consumption by using the bladder to be compressed and expanded by air; water supply systems Valves and pump switches will cause water hammer impact, and the surge tank can absorb this part of the impact, and can be used to replenish water in the system, reduce the number of times the pump starts and stops, prolong the service life of the pump, and save electricity. [0003] However, the surge tanks in the prior art are equipped with flanges on the top and bottom of the tank body, which increases the cost on the one hand, and increases the seal...
