Product Overview
|
Welding ball valve of imported thermal pipeline, Hot water welded ball valve， Also called heat Water pipe Tennis valve, welding ball valve for hot water supply, welding ball valve for hot water return, and ball valve for hot water pipe network in the community refer to the ball valve used for twenty # steel is the valve body, stainless steel is the ball, all welded connection is adopted, and carbon strengthening is adopted PTFE The negative pressure of the inclined elastic seal ring is on the spherical surface. It is used as the hot water pipe medium of the heating pipe network in various factories, so that the seal can achieve zero leakage and long service life

Advantages of welded ball valves in thermal pipelines
|
◆ No leakage: the product is seamless Steel pipe Press forming, integral full-automatic welding process. There is no leakage at the middle part and valve sleeve connection, which saves flange bolts and gaskets and reduces installation costs
◆ Zero leakage, 15 year maintenance free: the sealing ring is made of 25% carbon fiber PTFE, 25% carbon fiber material and disc spring loaded valve seat structure design, with strong adaptability to temperature and pressure changes. When the opening and closing times of the ball valve increase and the sealing surface is worn or the pipeline pressure is unstable, the disc spring mechanism behind the valve seat makes free compensation to ensure the close fit between the sealing surface and the ball and ensure zero leakage.
◆ Directly buried: The directly buried welded ball valve can be directly buried underground, instead of building a large underground well, it only needs to set a shallow well on the ground. According to the design requirements of the pipeline, the length of the valve stem can be adjusted, saving a lot of engineering time and construction costs.
◆ The valve has light torque and weight: the valve body is made of the same material as the pipeline, which will not produce uneven stress, reducing the bending stress of the pipeline. It can avoid deformation caused by vehicles passing through the ground or earthquake, with long service life and reduced project maintenance costs.

Product characteristics
|
one ）: No need for maintenance, adjustment and lubrication, easy to install, long-term reliable operation under low operating costs. The surface is treated with plastic spraying technology, with beautiful luster, which has reached the level of * * * in China. There will be no external leakage. The valve body is a welded structure, so the valve is light and easy to be insulated. The installation of the adjustment mechanism is very simple. The operating handle can be removed for reversing installation.
two ）: Since the valve seat is composed of carbon fiber reinforced Teflon seal ring and disc spring, it has strong adaptability to pressure and temperature changes, and will not produce any leakage within the marked pressure and temperature range.
three ）: The processing of the sphere is followed up by an advanced computer detector, so the processing precision of the sphere is high.
four ）: Since the valve body material is the same as the pipe material, there will be no uneven stress, nor will there be deformation due to earthquake and vehicles passing through the ground, and the pipe is aging resistant.
five ）Integral full welding, equal diameter and variable diameter channels, fixed ball and floating ball, double piston effect sealing system, automatic
Inject sealant type bearings.
six ）: In order to prevent static electricity, steel balls and springs are installed between the valve stem and the ball, as well as between the valve stem and the stuffing box, which can keep all parts of the valve conductive to the valve body, allowing the current to pass through the area and release static electricity. It can not only prevent fire, but also prevent corrosion, so as to realize temporary cut-off for timely maintenance.
seven ）: The valve stem anti falling function is because the valve stem is affected by the pressure inside the valve, and the total force of separation is generated, so the valve stem is designed as an anti falling structure.
eight ）: Use the thrust washer of low friction material to support and push the pressure to the valve stem, so that the valve stem only plays the role of transmitting torque.
