& Large diameter fully welded ball valve
The large diameter welded ball valve produced by Hebei Tongli Company adopts a fixed ball structure. This structural feature does not move after being compressed. It is designed with two sealing rings to provide sufficient pre-tightening force to ensure sealing. , achieving double-sided forced sealing and more reliable sealing performance.
The large-diameter fully welded ball valve can be buried directly underground, eliminating the need to build a tall valve well and reducing the project cost. It can also avoid personal injury when operating the valve. The large-diameter fully welded ball valve can operate reliably for a long time. When the valve is normal Under normal operation and use, the warranty period is more than one year.
Application scope of large diameter fully welded ball valve:
City gas: gas output pipeline, main line and branch line supply pipeline, etc.
Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment.
Heat exchanger: opening and closing of pipes and circuits.
Steel plant: various fluid pipelines, exhaust gas emission pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
Large diameter fully welded ball valve technical parameters:
Pressure level:
Working temperature: ℃& +℃
Connection method: welding, flange
Driving method: electric, Manual, turbine drive, gear drive, etc.
Technical features of large-diameter fully welded ball valve:
The valve body structure is integrally welded, and there will be no external leakage.
The valve seat is composed of a sealing ring and a spring and has strong adaptability to changes in pressure and temperature, and will not cause any leakage within the range of use.
, Anti-leakage structure of the valve stem. There is a self-sealing sealing gasket and a shaped sealing ring at the bottom of the valve stem. There is a shaped sealing ring and two sealing rings on the top to ensure no leakage.
The valve body material is the same as the pipe material, so there will be no uneven stress, nor will it be extruded and deformed due to earthquakes and vehicles passing over the ground.
The valve body is light and easy to keep warm.
. Directly buried ball valves can be buried directly underground. There is no need to build tall valve wells. Instead, only small shallow wells are needed 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.
The processing accuracy of the sphere is very precise, the operation is light, and there is no adverse interference.
There are two connection methods: welding and flange.
