2. Overview of the product
"Boang Brand" Double relief buried earth valve includes a ball valve body. A long stem with a pipe joint is connected to the switch joint of the ball valve body. The long stem includes a long stem. There is a protective tube on the outer cover, and a relief unit device is set in the pipe controlled by the ball valve body. It includes a relief base that is connected with the pipe. The long stems are fixed to each other, which is practical, easy to use and easy to open and close, which is conducive to pipeline inspection. It can also be buried directly underground without building a large high valve well. Instead, only a small shallow well can be set up on the ground, which greatly saves construction costs and engineering time. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
3. Performance characteristics
) It does not require maintenance, adjustment and lubrication. It is easy to install and operates reliably for a long time at low operating costs. The surface adopts spray plastic treatment technology and its gloss and beautiful appearance are at the leading level in China. There will be no external leakage and other phenomena. The valve body is of welded construction so the valve is lightweight and easy to insulate. It is very easy to install the adjustment mechanism. The operating handle can be removed for reversing installation
) Since the valve seat is made of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to changes in pressure and temperature. The marked pressure and There will be no leakage within the temperature range
) The processing process of the ball is tracked and detected by an advanced computer detector, so the processing accuracy of the ball is high
) Since the valve body material is the same as the pipe material, there will be no stress. They will not be deformed due to earthquakes or vehicles passing over the ground. The pipes are resistant to aging
) The integral, fully welded equal-diameter and variable-diameter channels use fixed ball and floating ball double-piston effect sealing systems to automatically inject sealant into bearings
/>) In order to prevent static electricity, steel balls and springs are respectively installed between the valve stem and the ball and the valve stem and the stuffing box to maintain the conductivity of all parts of the valve and the valve body, allowing the current to pass through the area to release static electricity. It not only prevents fire but also prevents corrosion and achieves temporary cutting for timely maintenance
) The valve stem anti-separation function is because the valve stem is affected by the pressure within the valve and always generates a force to escape, so the valve stem is designed with an anti-separation structure
) The thrust washer support with low friction material pushes the pressure to the valve stem so that the valve stem only plays the role of transmitting torque.

Land, installation precautions
The end welding of fully welded steel ball valves adopts electric welding or manual welding. Overheating of the valve chamber should be avoided. The distance between the welding ends cannot be too short to ensure that the heat generated during the welding process will not cause damage to the sealing material. All valves should be opened during installation.
