&The main application occasions of electric welding 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.
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 electric welded ball valves:
The electric welded ball valves produced by Hebei Tongli Company adopt a soft sealing structure and are designed with working seals and maintenance seals. The operating torque is small, the sealing specific pressure is moderate, the sealing is reliable, and the action is sensitive. , hydraulic control is easy to realize automatic control and has long service life. The pressure and temperature rating of the ball valve is not only related to the shell material, but also more related to the seal materials such as valve seat, packing and gasket. Seals can be made of polymer materials, asbestos or rubber. The choice of seal material depends on the composition of the medium transported by the valve, working temperature, working pressure and flow rate.

Structural features and functions of electric welded ball valve:
Advanced valve seat: The valve seat is designed based on many years of ball valve manufacturing experience, with low friction coefficient and small operating torque. A variety of valve seat materials, suitable for a wide range of applications.
Valve stem anti-flying structure: Set a step at the lower part of the valve stem, and install the valve stem from the inside of the valve body to prevent the valve stem from flying out.
Anti-static function: An anti-static spring is installed between the ball and the valve body or valve stem, which can discharge the static electricity generated during the switching action.
Fire-resistant structure: Advanced fire-resistant design. After a fire, each leakage part is designed with flexible graphite filler or stainless steel sandwich graphite to meet fire-resistant requirements and comply with the regulations of China and Japan.
When operating the handle, a flat-head valve stem is used, and the connection with the handle will not be misaligned, thus ensuring that the switch status indicated by the handle is consistent with the valve. In order to prevent the valve switch from malfunctioning, locking holes are provided at the fully open and fully closed positions of the switch to ensure that the valve is in the correct position.
. Fire-resistant structure: Advanced fire-resistant design. After a fire, the seals at each leakage location will be burned to form a metal-to-metal seal, which complies with the regulations of Japan and Japan. For places with strict fire resistance requirements, the seals are sealed with flexible graphite fillers and stainless steel clamped graphite gaskets to ensure no leakage. (Please specify when ordering: fully fireproof type B)
The valve adopts the most advanced support plate structure at home and abroad, which increases the service life of the valve and reduces the operating torque of the valve. Greatly extends the service life of the valve.
