Q946F electric four-way ball valve

I. Overview:
Q946F electric four-way ball valve is composed of angular stroke electric actuator and four-way ball valve, in the mining, refining and processing of oil, natural gas, coal and ore and pipeline transportation system; In chemical products, medicine and food production; In electricity production systems for hydropower, thermal and nuclear power; In the water and drainage, heat and gas supply systems of cities and industrial enterprises; In the drainage and irrigation systems of agricultural fields; In the gold production system; It is an important mechanical product closely related to production and construction, national defense construction and people's life.

Ii. Product Features:
1, the manual part can use steel plate pressing handle or stainless steel casting handle. The handle is provided with a limit structure to set a limit at the opening and closing position of the valve. When the valve is used on the key device, the limit block is provided with a lock hole to lock the switch position to avoid misoperation. There is an obvious opening and closing mark on the handle.
2, the valve stem adopts A182F (1Cr13) whole forging and modulation treatment, the hardness reaches HB220 ~ 250. The valve stem is connected with the handle through the flat key or spline or square contract, which is convenient for disassembly and assembly and strong versatility. The valve stem is provided with an anti-blowout structure.
3. The packing of the valve is braided, flexible graphite sealing ring or tetrafluoroene sealing ring, so that the valve stem can achieve reliable sealing under certain lubrication conditions.
4, according to the need, the ball valve can be designed into an anti-static structure, in the sphere and the stem, the stem and the valve body between the conductive spring, to avoid the electrostatic spark ignition flammable substances, to ensure the safety of the system.
5. Various forms of sealing. According to different working conditions can choose soft seal, hard seal, fire valve seat and other structures; Below DN150 is the floating ball form, below DN200 is the fixed ball form.
6, the ball valve seat can be set an auxiliary sealing structure, in the seat and stem parts of the grease valve, emergency can be temporarily sealed, and according to the need to extend the valve stem to suitable for buried laying places.
