1. The products adopt foreign advanced production technology, monitor the whole process with high-precision testing instruments, and are manufactured with high-precision CNC machining centers. The main components are imported from abroad to ensure product quality.2. The design of this product is reasonable. The high-quality ductile iron and stainless steel make the overall combination of the product sturdy and durable. The main body is designed to last as long as 8 years.
3. No professional installation is required. The "water supply" and "drainage" signs on the upper valve handwheel are simple and easy to understand, and can be operated by all ages. "Open valve to discharge water, close valve to prevent freezing", which is very simple to use.
4. When the temperature is expected to reach freezing temperature in the cold winter, operating the handle of this product can empty the water in the water pipe exposed above the ground to achieve a complete anti-freezing effect. It completely solves the problem of freezing and cracking of water pipes in cold areas and unable to take water.
5. After the standpipe antifreeze plug is installed, there is no need to wrap any insulation material, and use water at any time to prevent freezing at any time. It is not only high-end and beautiful, but also saves a lot of insulation materials.
Connect the water inlet elbow made of PE material to the main water pipe made of PE material by hot melt. (If the main underground water pipeline is a metal pipe, the water inlet elbow should use a metal inner wire elbow, one end is connected to the anti-freeze plug water inlet, and the other end is connected to the main pipe with a transition piece).
Wrap the thread of the water inlet of the lower valve body of the antifreeze valve (bolt) evenly around the raw material tape and screw it into the Rc1/2 thread of the water inlet elbow in a clockwise direction. At the same time, adjust the direction of the water outlet, whichever is tightened. Excessive force or violent operation, so as not to cause damage to the water inlet thread.
Stack bricks on the lower part of the inlet elbow to form a support to prevent the bolt from lifting and sinking. The permeable layer is filled with stones or broken bricks with a diameter of ≧4-6 cm, and the filling height should be buried to about 3 cm above the lower valve body. Cover the water-permeable layer with plastic sheet and fill the antifreeze layer with pure soil.
Note: H in the figure represents the depth of the frozen layer when the local temperature is the lowest. It should be 50cm-70cm in Shandong area to prevent sudden and large temperature drop. Therefore, the antifreeze layer depth H should be greater than 50cm to ensure that the valve body under the antifreeze valve (plug) is below the frozen layer line. The permeable layer J≧40cm to ensure that there is enough space for drainage.
It is recommended that the section size of the installation pit is not less than 40cm×40cm square or a circular pit with a diameter not less than 50cm. To facilitate installation and operation.
4.1.4 Step 4: Install the faucet on the outlet of the antifreeze valve, tighten it and use it.
4.1.5 It is recommended to install the main valve in front of the valve body under the antifreeze valve (bolt) for easy maintenance. The installation standard of the water meter can be implemented by the user according to the requirements of the local water administration department.
4.2 Instructions for use:
Operate the handwheel of this product and turn it in the direction of "water supply" indicated by the arrow to the end, and then you can use it normally; turn it in the direction of "drainage or antifreeze" indicated by the arrow on the handwheel to the end, and then be sure to turn on the faucet to prevent freezing. Twist the handle to the end every time you use water or antifreeze. It is strictly forbidden to screw the handle wheel to the intermediate state of water and antifreeze to prevent invalidation. In the season when antifreeze is not required, the handwheel of the antifreeze plug can be set in the water supply state to control the normal water consumption of the faucet.
5.1 When installing this product, please clean up the dust and dirt on the upper and lower valve bodies and piping of this product.
5.2 After purchasing this product, do not place it in a place with high temperature and dryness or direct sunlight, nor place it in a place prone to ozone.
5.3 It is strictly forbidden to use this product in non-tap water pipelines.
5.4 When screwing the antifreeze valve (bolt) into the water inlet elbow, use a wrench to clamp the hexagonal part of the water inlet elbow and tighten it. Do not use a pipe wrench to rotate the pipe body directly to avoid damage to the pipeline.
5.5 During the installation process, a dedicated person should hold the antifreeze valve (bolt) pipe body until the installation pit is filled, so as to avoid damage to the pipeline due to the gravity of the backfill. When backfilling soil, be careful not to block the drain on the lower valve body of the antifreeze plug to prevent equipment failure.
5.6 After the installation is completed, the confirmation of water supply, water stop, and drainage should be carried out. When the product is operated, it is normal to close the faucet without leaking, and open the faucet to produce water. It is normal to put your hand on the faucet and feel a sense of adsorption when draining. Before backfilling the soil, a water flow test should be carried out to confirm that there is no water leakage at the elbow joint and the hot melt before it can be filled with soil. The landfill soil should be soft, and mixed soil containing a lot of stones or bricks should not be used to ensure the thermal insulation effect of the backfill soil.
5.7 Rotate to the end according to the "drainage or antifreeze" direction on the hand wheel, and open the faucet to empty the water in the water pipe exposed above the ground to achieve a complete antifreeze effect.
5.8 Do not disassemble, disassemble, or modify without permission, otherwise the parts will be damaged or leaked.
5.9 The user is not allowed to perform rough operation during installation or use to prevent exceeding the bearing limit of the valve body to prevent damage to the equipment.
5.10 If the antifreeze valve (plug) is installed at the end of the main water pipe, the water inlet of the antifreeze valve (plug) can be directly connected to the main pipe; if multiple antifreeze valves (plugs) are installed along the main water pipe, they should be installed from the main water pipe first. Connect the branch pipe with a three-way connection and connect the water inlet of the antifreeze valve (plug) to the branch pipe, so as not to affect the normal use of other antifreeze valves (plug).
