Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a cold storage pressure pipe fitting. Background Art

[0002] Cold storage is a type of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment with a different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items.

[0003] Cold storage is generally divided into water-cooled and air-cooled. Water-cooled cold storage has the advantages of high refrigeration efficiency, good stability, environmental protection and energy saving. It is particularly suitable for large cold storage or occasions requiring high cooling performance. Water quality issues need to be considered to prevent corrosion and scaling of the cooling system.

[0004] Most of the existing gate valves in the water-cooling pipes of cold storages are blocks from top to bottom, and there is a groove at the bottom that matches the block to achieve a tight closure. However, with long-term use, some mud and impurities will accumulate in the groove, blocking the closure of the block, resulting in a loose closure. In addition, the inner cavity may be blocked after a long period of use, and it is troublesome to disassemble and clean it regularly. For this reason, we propose a cold storage pressure pipe fitting. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1) A blocking net is installed at the front end of the housing, and a cylindrical filter screen is inside the blocking net. Before water enters the gate valve, it first passes through the blocking net, which filters out impurities in the water, reducing the blockage of the gate valve by impurities in the water and preventing corrosion of the water-cooled pipeline. The structure of the device is simple and easy to use.

[0013] 2) The device is provided with a first stopper and a second stopper. The second stopper is a convex block, and the first stopper is a concave block.
