Antifreeze valve installation problems and instructions for use

The antifreeze valve should be installed below the frozen layer or in a place where it is not frozen, that is, the antifreeze valve must not be frozen, otherwise the antifreeze function will be lost. The antifreeze valve should be installed before the tap water pipe that may freeze, that is, the freezing of the tap water pipe within the control range of the antifreeze valve can be prevented. When installing the antifreeze valve for a single-family multi-storey building, it can be installed behind the main valve of the household water meter to control all the tap water pipes in the household to prevent all the water pipes in the house from freezing. Especially for some idle houses in the building, because there is no temporary living, there is no heating, and it is very suitable to install the antifreeze valve. When installing antifreeze valves in rural housing and industrial and mining enterprise sites or public squares, the antifreeze valve can be installed in an inspection well. The depth of the inspection well is set according to the depth of the local frozen layer. It is necessary to install the antifreeze valve below the depth of the frozen layer. For ease of operation, the operating handle can be extended with the extension rod to near the ground or exposed to the ground. After installing the antifreeze valve, the tap water pipe after the antifreeze valve will not freeze.

Operation of the antifreeze valve handle to drain water from the antifreeze valve drain when draining

When installing antifreeze valves in rural housing and industrial and mining enterprise sites or public squares, there must be a 10-20 cm water seepage space under the water outlets of the antifreeze valves. The water discharged from the antifreeze valve drains is discharged into this space and penetrates into the ground. When installing the antifreeze valve in a single-family multi-storey building, it can be connected from the drain port of the antifreeze valve to the main drain pipe in the building pipe well, so that the water discharged from the antifreeze valve is led to the drain pipe; The drain port of the valve is connected to the drainage floor drain of the indoor or the indoor drain pipe. When connecting to the indoor drain pipe, a water basin is needed at one end of the drain pipe to put the water discharged from the antifreeze valve into the water basin. Use, this can save water.

Before you install the antifreeze valve , you should know the following:
Please read the installation and operation manual carefully before installation.
Be sure to remove dust and foreign matter from the product and the connecting piping during installation.
Confirm that the horizontal piping from the product is not less than 1/100.
When installing the inspection well, make sure that there is a 10-20mm water seepage space under the drain of the product.
Avoid rough handling, it is strictly forbidden to warm or expose this product. It is strictly forbidden to use this product in non-water pipelines.
When installing, be sure to determine the direction of water in the direction indicated by the arrow on the main body of the product.
Be sure to install this product below the freezing depth. When installing above the ground, make sure that the pipe before this product is not frozen. The pipe after this product does not need any insulation.
It is expected that when freezing at low temperature may occur, rotate it in the direction of the drain arrow on the handle of the product, and open the faucet to completely drain the water. After draining, close the faucet.

The following is a detailed introduction of the three antifreeze valve series independently developed by Jinghua .

菁华昱创_Pipe antifreeze valve

1. Antifreeze valve product introduction

The safety antifreeze valve prevents freezing of the domestic water system and avoids damage to the water tank or pipeline caused by freezing. It is used in solar energy and outdoor living water systems. When the ambient temperature drops to approximately 4 ° C, the antifreeze valve opens and the safety antifreeze valve opens automatically, keeping a portion of the water flowing out, and the minimum flow rate is prevented from freezing. When the ambient temperature rises or the water temperature rises, the safety antifreeze valve automatically closes and returns to normal operation. The faucet is integrated with the safety antifreeze valve for easy installation and is suitable for outdoor water systems without insulation.

2, antifreeze valve product features

1. Automatic protection: The antifreeze valve generates self-acting action through the temperature sensing of the temperature, and can automatically open and close without external power, thus protecting the safety of the water system.

2, high control accuracy: the opening temperature of the antifreeze valve is 4 ± 1 °C.

3, easy to install: use the universal G1/2 pipe thread interface.

4. Compact structure and beautiful appearance.

  

3. Working principle of antifreeze valve

The antifreeze valve safety valve has a built-in thermal element (1) that contacts the ambient temperature to control the opening and closing of the piston (2) and the valve seat. When the ambient temperature is lower than the set value, the contraction of the thermosensitive element drives the piston to open the drain passage downward, so that a small amount of a part of the water flows out, and the continuous water flow avoids the freezing of the pipeline. After the water temperature in the pipeline is flowing, the temperature is usually higher than the temperature of the outside air. When the temperature exceeds the set closing value, the expansion of the thermal element drives the piston to close the drain passage. The system resumes normal operation. In order to ensure good antifreeze operation, it is necessary to ensure that the upstream of the safety antifreeze valve is the normal tap water supply pressure.

菁华昱创_Solar antifreeze valve

product description

The antifreeze valve is an accessory product specially developed for solar water heaters. Its main function is to prevent the heat collecting plate of the solar water heater from being destroyed by ice. The antifreeze valve is installed in the heat collecting plate of the solar water heater (as shown in the schematic diagram). When the temperature is lowered to about 4 °C, the antifreeze valve is opened, so that the cold water of the heat collecting plate can be discharged in time; and the warmth of the water storage tank is timely replenished. Water to the collector plate. When the warm water reaches the inside of the antifreeze valve, the antifreeze valve automatically closes.

Features

1. Automatic protection: The antifreeze valve generates self-powered action by sensing the temperature through the warm pack, and can automatically open and close without external power, thus protecting the safety of the solar water heater collector plate.

2. High control precision: The opening temperature of the antifreeze valve is 4 ± 1 °C.

3 , easy to install: use the universal G1/2 pipe thread interface.

4 , compact structure, beautiful appearance.

Product installation:

Before installing the antifreeze valve , the solar water heater should be thoroughly rinsed to ensure that no foreign matter is present. In order for the antifreeze valve to work properly, the antifreeze valve should be installed vertically (as shown in the schematic diagram).

Product Maintenance:

In order to make the antifreeze valve work normally, the foreign matter impurities and sediment entering the antifreeze valve should be cleaned regularly.

PC Wire

PC wire is used in major construction projects as a means of increasing the strength of cast concrete components, ranging from railway track sleepers, ground stabilizing piles, floor beams and pipe systems. The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
