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 electromagnetic valve. Background technique [0002] Solenoid valves are used in all walks of life due to the convenience and speed of their control, and with the continuous expansion of the scope of use, different types of solenoid valves have appeared on the market. [0003] As a kind of solenoid valve, the waterproof solenoid valve is installed on the pipeline immersed in the liquid because of its waterproofness. Due to being soaked in the liquid for a long time, for the waterproof solenoid valve used outdoors, the temperature of the liquid also changes with the seasons, causing the valve of the waterproof solenoid valve to expand with heat and contract with cold, which is easy to cause The sealing of the sealing area fails, so that water enters the interior of the waterproof solenoid valve and damages the waterproof solenoid valve.
