The invention provides a waterproof electromagnetic valve, and belongs to the technical field of control valves. The waterproof electromagnetic valve comprises a barrel-shaped waterproof shell with wall body axially provided with a spiral channel, a waterproof cover is arranged at the barrel opening of the waterproof shell, meanwhile, a valve rod of a valve body penetrates through the waterproof cover to extend into the waterproof shell, two connecting heads are arranged on each of the outer wall and the inner wall of the waterproof shell, and the two connecting heads on each side communicatewith the two ends of the spiral channel correspondingly. According to the waterproof electromagnetic valve, a heating component is arranged in the spiral channel in a penetrating mode to heat the waterproof shell, and a gap formed by cold contraction of the waterproof cover is supplemented through expanding of the wall thickness of the waterproof shell in a cold-temperature environment so that thewaterproof failure can be prevented; and the spiral channel can be connected to a cooling water circulation device so that the waterproof shell can be cooled, the problem of expansion and extrusion due to thermal expansion of the waterproof cover is avoided through the cold contraction of the wall thickness of the waterproof shell in the high-temperature environment, the problem of waterproof failure caused by damage to the shell is avoided, the safety guarantee is higher, and the waterproof performance is better.
Description
Technical field [0001] The invention relates to the technical field of control valves, in particular to a waterproof solenoid valve. Background technique [0002] Solenoid valves are applied to all walks of life due to their control convenience and rapidity, and with the continuous expansion of the scope of use, different types of solenoid valves appear on the market. [0003] Waterproof solenoid valve, as a kind of solenoid valve, is installed on a pipeline immersed in liquid due to its waterproofness. Because of being immersed in liquid for a long time, for waterproof solenoid valves used outdoors, as the season changes, the temperature of the liquid also changes, causing the valve of the waterproof solenoid valve to expand and contract with heat, which is easy to cause The sealing of the sealing area fails, so that water enters into the waterproof solenoid valve and damages the waterproof solenoid valve. Summary of the invention [0004] In view of the above-mentioned problems ...
