Fully welded ball valve
Fully welded ball valve overview:
Fully welded ball valve is widely used in various fields. Its superior quality and high performance stability are beyond the reach of ordinary cast steel ball valves. Fully welded ball valve The service life is much longer than that of cast steel ball valves. Fully welded ball valves are widely used in various pipeline equipment such as city gas, city heating, petrochemical industry, shipbuilding, steel, pressure regulating stations, power plants, etc. Fully welded ball valves can be buried directly underground. There is no need to build tall valve wells to reduce project costs. At the same time, it can also avoid personal injury when operating the valve. Fully welded ball valves can operate reliably for a long time. Under normal operation and use of the valve, the warranty period Year.
Application occasions of fully welded ball valves:
City gas: gas output pipelines, main lines and branch line supply pipelines, 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.
Technical features of fully welded ball valves:
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.
, Operation mode: handle, gear (vertical/horizontal)
, Under normal operation and use of the valve, the warranty period is one year.
