Electricity accompanies the heat in the water valve accompanies the heat of the usage

In the cold environment, the normal operation of the water valve faces the challenge, and the electric accompanying heat becomes the effective means to guarantee the function of the water valve. Correct use of electric accompanied by heat in the water valve accompanied by heat, not only can prevent the water valve freezing damage, but also can ensure the stable operation of the whole water system, which has a lot of need to grasp the key points.

Selection is the key

1. Temperature requirement: first of all, we should consider the lowest temperature of the environment where the water valve is located, and choose the electric accompanying heat tape with suitable temperature resistance level. For example, in the cold northern region, the lowest temperature in winter may reach - 20 ℃ or even lower, it is necessary to choose can work normally in the low temperature environment and can maintain the water valve in the appropriate temperature (such as 5 ℃ or more) electric accompanied by tropical, like self-limiting temperature electric accompanied by tropical in the low-temperature type products.

2. Power adaptability: According to the size of the water valve, material and heat dissipation to determine the power of the electric accompanied by tropical. Large diameter metal water valve due to fast heat dissipation, may need higher power electric accompanied by tropical, in general, each meter power in 10 - 30 watts between the choice, to ensure that there is enough heat to make up for the heat dissipation, to prevent the water inside the water valve icing.

Installation preparation

1. Surface cleaning: Before installing the electric accompanied by the heat tape, the surface of the water valve must be thoroughly cleaned to remove oil, dust and rust and other impurities. The clean surface can ensure the electric accompanying tropical and water valve good fit, improve the heat conduction efficiency. For example, you can use sandpaper to gently polish the rust on the surface of the water valve, and then wipe it clean with a clean cloth.

2.Measurement and cutting: Accurately measure the length of the part of the water valve which needs to accompany the heat, and then cut the suitable length of the electric accompanying heat tape. Cutting should pay attention to follow the product instructions to avoid damage to the internal structure of the electric heating tape. Generally use professional scissors or cutting tools to make sure the cut is neat.

Installation points

1. Winding method: The electric heating tape will be wound evenly in the water valve in spiral shape, to ensure that the heating tape is in close contact with the surface of the water valve, and there can be no gap. For the irregular shape of the water valve, can use the multi-turn winding or local key winding way. For example, the valve stem part of the water valve heat dissipation is faster, can be appropriate to increase the number of winding circle.

2. Fixing method: Use special fixing tape or aluminum foil tape to fix the electric heating tape on the water valve, and fix it every certain distance (such as 30 - 50cm). In the process of fixing, we should pay attention to not too tight, so as not to crush the electric accompanied by the tropical, and at the same time also to prevent the accompanied by the tropical loosened and shifted.

The usage of electric accompanying heat in water valve accompanying heat needs to be carefully operated from the selection, installation preparation to the specific installation of each link. Only in this way, can give full play to the role of electric accompanying heat, effectively protect the water valve from freezing damage, guarantee the safe and reliable operation of the water system.
