& Single flange fully welded ball valve is specially developed by Hebei Tongli Company according to user requirements. The single flange fully welded ball valve can be welded individually and the other end is connected in a flange manner.
The reason for the design of single flange fully welded ball valve is that after other valves are installed in the pipeline, the fully welded ball valve cannot be directly installed. Based on this situation, Hebei Tongli Company specially studied the single flange fully welded ball valve. The flange end can be connected to other valves or pipe flanges, and the other end is connected by welding to facilitate the replacement of valves at the flange end.
Application occasions of single flange fully welded ball valve:
City gas: gas output pipeline, main line and branch line supply pipelines, etc.
Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment.
Steel plant: various fluid pipelines, exhaust gas emission pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Heat exchanger: opening and closing of pipes and circuits.
Various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
Structure and design of single flange fully welded ball valve:
Single flange fully welded ball valve is manufactured in full accordance with the design and is fireproof and anti-static. The valve stem is lengthened according to user requirements, and metal parts such as the valve body and ball are all made of forged high-quality materials, ensuring the quality and strength of the ball valve. The sphere is fixed with a stuffing box or support plate. The stuffing box or support plate fixed ball can eliminate the bending moment of the valve stem caused by the force of the medium acting on the ball, so that the valve stem only bears torque. And the low-friction Teflon composite bearing is fixed around the ball. The valve moves smoothly, the switching torque is small, and it is easy to operate. The seal uses a unique two-layer soft seal and a metal seal to form a triple seal. Ensure reliable sealing and safe use. Long life and maintenance-free.
Technical features of single flange fully welded ball valve:
The valve body structure has single flange and single welding, so 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 is light and easy to keep warm.
. Single-flange fully welded ball valves can be selected according to the diameter of the pipeline flange. The length of the valve body and the height of the valve stem can be adjusted according to construction and design requirements.
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
