In foretell valve heating insulation bag, fixing device includes the magic subsides, and the magic subsides can bond each other, are convenient for fix.

In the valve heating insulation bag, the fixing device comprises a binding belt which prevents the insulation bag from separating and clings to components such as the valve. Furthermore, the fixing device is a magic tape and a binding belt, so that the heat preservation and the binding effect are effectively achieved.

In the valve heating heat-insulating bag, the anti-freezing solution is pre-filled in the bag body. The antifreezing solution has the characteristics of safety in heating and the like.

In the valve heating insulation bag, the antifreeze is glycol antifreeze. The bag is filled with glycol type antifreeze fluid which can not be frozen at minus 45 ℃ and has safe heating performance.

In the valve heating thermal insulation bag, the bag body is provided with a filling port, and when the valve heating thermal insulation bag is used, the antifreeze can be filled through the filling port, so that the space of the thermal insulation bag is saved.

In the above valve heating insulation bag, the heating device is an electric heating device.

In the above valve heating insulation bag, the electric heating device comprises an anti-creeping device.

An electric heating device is arranged on the side surface of the heating bag, and the voltage of the electric heating device can be 220V, 24V or 12V. When the electric heating device with the voltage of 220V is installed, an electric leakage protection switch is required to be additionally installed on a line, and when the electric heating device with the voltage of below 36V is installed, the electric leakage protection switch is not required to be installed. The upper part of the heating bag is provided with the breather valve, when the heating bag is heated, the volume of the bag can be changed, and the breather valve is arranged to prevent the bag body from expanding and cracking.

The electric heating device is arranged at the left position in the middle, when the heating bag is wrapped on the transversely arranged valve, the heating device can be ensured to be at the lowest position, and when the valve is vertically arranged, the heating device can also be at the lowest position. The upper portion at the heating bag installs the breather valve, and the breather valve is installed at middle position to the right side, no matter the valve transversely sets up or sets up upright, can both guarantee the breather valve in the position of the top. When the heating bag is heated, the volume of the bag can be changed, and the breathing valve can automatically discharge expanded gas to prevent the bag body from expanding and cracking.

In the above valve heating insulation bag, the electric heating device comprises a temperature control device. Temperature control devices, such as a temperature control switch and a temperature detection device, are mounted on the circuit outside the heating bag for controlling the heating and maintaining the temperature of the liquid in the bag.

The inventor designs that a heating insulation bag is made of two layers of rubber and is wrapped outside a valve, and when the heating insulation bag is used, the heating bag is electrified and heated to keep the working temperature of a metal part and prevent the valve from being frozen and cracked.

The valve is suitable for vehicle-mounted valves of fire trucks and mine watering lorries, and metal parts which are afraid of frost cracking and the like in winter in northern China.

Has the advantages that:

the technical scheme has the advantages of simple material consumption, convenient use, no waste of antifreeze, no possibility of bag expansion, capability of being used for filling at present, capability of being pre-filled, simplicity and portability, capability of ensuring that the antifreeze is not frozen at 45 ℃ below zero under the condition of no power supply after being installed and used and wide application range, and the ethylene glycol type antifreeze is added into the bag body. Is not only suitable for conventional fixed appliance valves, but also suitable for vehicle-mounted valves of fire trucks and mine watering lorries, metal parts which are afraid of frost cracking and the like used in winter in the north of China,
