Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a built-in electrically controlled drain valve, such as Figures 1 to 5 As shown, the device includes an electrically controlled drain valve body 1, which includes a valve pipe and a solenoid valve 101 disposed on the surface of the valve pipe. A connecting wire 102 is electrically connected to one side of the solenoid valve 101. An insulation component 2 is disposed on the outer surface of the electrically controlled drain valve body 1. The insulation component 2 includes insulation sleeves 201 tightly attached to both sides of the outer surface of the valve pipe. Hinge seats are disposed on both sides of the insulation sleeves 201. A placement groove is disposed inside the insulation sleeves 201, and a heating resistance wire 202 is disposed inside the placement groove. Conductive wires are disposed on both sides of the heating resistance wires 202, and the conductive wires are connected to an external power source. A connecting plate is fixedly installed on the outer surface of one side of the insulation sleeve 201. 203. On the other side, the outer surface of the insulation sleeve 201 is provided with a positioning frame 204. The connecting plate 203 is adapted to the positioning frame 204. The upper surface of the positioning frame 204 is slidably connected to both sides with insert rods 205. Pulling plates 206 are fixedly installed on the top of the insert rods 205 on both sides. The surface of the connecting plate 203 is provided with insertion holes, which are adapted to the insert rods 205. A first spring 207 is provided between the pull plate 206 and the positioning frame 204. A temperature sensor is provided on the inner side wall of the insulation sleeve 201. The temperature sensor is electrically connected to an external power source. An arc-shaped groove is provided inside the insulation sleeve 201. An antifreeze layer 208 is provided inside the arc-shaped groove.

[0027] The worker installs the insulation component 2 onto the outer surface of the valve tube in the body 1 of the electrically controlled drain valve. The insulation sleeves 201 on both sides are rotated so that they fit onto the outer surface of the valve tube in the body 1. Before installation, the worker pulls the plate 206 to disengage the lower insert rod 205 from the positioning frame 204. Then, the connecting plate 203 on one side of the insulation sleeve 201 snaps into the positioning frame 204. The worker then releases the pull plate 206, and the restoring force of the first spring 207 causes the insert rod 205 to insert into the surface of the connecting plate 203, thus allowing the two insulation sleeves to fit together. The insulation sleeve 201 on the side is fixed relatively, so that the insulation component 2 is installed on the outer surface of the valve tube in the body 1 of the electric control drain valve. The insulation component 2 and the body 1 of the electric control drain valve are built into the device. The temperature sensor detects the ambient temperature. When the temperature is lower than the threshold of the temperature sensor, the external power supply is automatically activated, so that the heating wire 202 generates heat and transfers the heat to the valve tube in the body 1 of the electric control drain valve, thereby ensuring that the water inside the valve tube will not freeze. This avoids the situation where the water inside the electric control drain valve freezes and becomes unusable, ensuring the normal use and stability of the electric control drain valve.

The pull parts 7 drive the plug block 5 out of the groove and squeeze the second spring 6 inside, so that the mounting ring 4 and the filter plate 3 can be removed from the inside of the valve pipe. When installation is required, the reverse is true, which makes it easy for the staff to carry out disassembly and assembly operations.

[0031] Both ends of the valve pipe are provided with threaded connecting pipes 8, and the side surface of the threaded connecting pipes 8 is provided with sealing grooves.
