I want to answer you, the quick joints of fire hoses are generally made of aluminum. There are two processes of casting and die casting. The back-casting hose joints will be better in terms of structure and stability.
Pay attention to these when installing:
1. Connect the inner buckle interface: the buckle claw should be inserted into the chute and then screwed into place in a clockwise direction. When connecting the agricultural water belt, it is also necessary to straighten the water belt to prevent the agricultural water belt from being twisted and the interface will be disengaged by itself.
2. The joint should not be too tight or too loose brass pipe fittings supplier
during installation, and the strength should be moderate to prevent slippage. The non-slip pad of the joint must be in line with the thread to prevent water leakage.
3. The joint should be prevented from falling, bumping and heavy pressure to prevent deformation and difficult assembly and disassembly. Before connecting, the chute and sealing part should be carefully checked. If there is any debris such as sludge and sand, it must be removed to avoid poor sealing and assembly and disassembly. difficulty.
In terms of material, the hose joints include aluminum and plastic joints, and aluminum joints are often used for fire hoses.
The competition for products with low technical content such as gate valves is the most fierce. Gao Jinhua told reporters that infrastructure construction is the focus of my country's economic construction. water industry. It provides a good opportunity for the development of the valve industry. Valves in the water treatment industry are mainly low-pressure valve products, such as butterfly valves, gate valves, and check valves. In water supply and drainage projects, medium and low pressure valves are widely used, especially low pressure large diameter valves (low pressure valves refer to valves with nominal pressure PN≤1.6MPa), while medium pressure valves (PN2.5-6.4MPa) are less. The gate valve and butterfly valve are the most basic and widely used leading products.
