[0004] According to the problems in the background, the utility model solves the problems: provide a kind of waterproof electromagnetic valve applied to blood component separation, ensure good waterproof performance by rubber sheath and sealing ring, ensure that water can flow into water collecting groove through the spiral thread in the event of water leakage, prevent further leakage of water.
[0005] To achieve the above object, the utility model provides the following technical scheme: provide a kind of waterproof electromagnetic valve applied to blood component separation, including core, reset spring, spring seat, shell, rubber sheath, spiral thread, rubber sealing ring and rubber water collecting groove, the shell is the main body structure of the cylindrical style of electromagnetic valve, spring seat is installed on the upper end of shell, spring seat is concentric with shell, reset spring is installed on the upper end of spring seat, reset spring is concentric with spring seat, core is installed on the upper end of reset spring, core is concentric with reset spring, rubber sheath is covered on core, reset spring and spring seat, spiral thread is covered on the outer surface of rubber sheath and is covered from the uppermost end of rubber sheath to the lowermost end, rubber sealing ring is installed at the junction of spring seat and shell and rubber sealing ring is in contact with rubber sheath, rubber water collecting groove is covered on the outer surface of shell and is in upper opening style.
[0006] The rubber sheath is a cylindrical body with an inner cavity and an open lower end, and the lower end of the rubber sheath is in interference fit with the spring seat, ensuring that the rubber sheath can be firmly installed on the spring seat.
[0007] The rubber sealing ring is in the form of a circular ring with two protrusions on the circular ring, and the rubber sealing ring is in interference fit with the spring seat, ensuring that the rubber sealing ring can be firmly installed on the spring seat.
[0008] The lower end of the spiral pattern is connected to the upper protrusion of the rubber sealing ring, allowing liquid to flow down along the pattern.
[0009] The rubber water tank is detachable, allowing it to be emptied when full.
[0010] The beneficial effects of this utility model are:
[0011] 1. Good waterproof performance is ensured by setting rubber sleeves and rubber sealing rings.
[0012] 2. By incorporating spiral patterns and a water collection trough, it is ensured that in the event of a leak, water can flow through the patterns into the water collection trough, preventing further leakage.
[0013] 3. Simple structure, easy to manufacture, and reliable in use. Attached Figure Description
