Novel anti-freezing valve

Abstract

The invention discloses a novel anti-freezing valve. The novel anti-freezing valve comprises a first half shell, a second half shell, a valve body and an air nozzle. The first half shell and the second half shell are of the same structure. The first half shell comprises a first heat preservation layer, a second heat preservation layer, fixing blocks, threaded holes and a label; the shell is provided with the first heat preservation layer and the second heat preservation layer from outside to inside, and the label is arranged on the outer surface of the shell; the fixing blocks are welded to the first half shell and the second half shell, and the threaded holes are formed in the centers of the fixing blocks; and the valve body is wrapped with the second heat preservation layer. The first heat preservation layer is made of a heat preservation sponge and thus used for avoiding the situation that outside air directly penetrates through the heat preservation layers; the second heat preservation layer wraps the valve body all-dimensionally without a dead corner, the air achieves the good insulation and heat preservation effects, thus the heat preservation mode is more comprehensive, andthe heat preservation effect is better; and workers can conveniently understand the usage of the valve through the label.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel antifreeze valve. Background technique [0002] The valves we currently use are easy to freeze in winter, so we will wrap a layer of foam on the valves and pipes to prevent the pipes from freezing to ensure that the valves are not damaged by freezing, but this insulation effect is poor, still It will freeze the valve. Contents of the invention [0003] The purpose of the present invention is to provide a new type of antifreeze valve to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a novel antifreeze valve, including a first half shell, a second half shell, a valve, and an air nozzle, and the first half shell and the second half shell have the same structure , wherein the first half-shell includes a first insulation layer, a second insulation layer, a f...
