I. Overview of Q41F stainless steel ball valve :
Product model: Q41F
Nominal diameter: DN15-200mm
Nominal pressure: PN1.0-4.0Mpa
Applicable medium: nitric acid, acetic acid Applicable temperature: ≤150 degrees Drive mode: manual, pneumatic, electric
Second, the main purpose of Q41F stainless steel ball valve:
Ball valves are used in the mining, refining and processing of oil, natural gas, coal and ore, and in pipelines; in the production of chemical products, medicine and food; in the power production systems of hydropower, thermal power and nuclear power; , Heating, and gas supply systems; in farmland drainage and irrigation systems; widely used in metallurgical production systems, is an important mechanical product closely related to production and construction, national defense construction and people's lives. The ball valve is sealed in various piping systems to cut off or connect the medium flow, so that the medium is delivered to various designated points according to a predetermined procedure.
Third, the main material of Q41F stainless steel ball valve :
Stainless steel plus flexible graphite
软钢 08 mild steel
Water, steam, oil
Partial acid and alkali
Fourth, the main features of Q41F stainless steel ball valve:
1. The manual part can be a handle made of steel plate or a handle made of stainless steel. The handle is provided with a limit structure. The limit is set at the position where the valve is opened and closed. When the valve is used on a key device, a lock hole is provided on the limit block to lock the switch position to avoid misoperation. There are clearly open and closed logos on the handle.
2. The valve stem is made of A182F (1Cr13) as a whole and forged, and its hardness reaches HB220 ～ 250. The valve stem is connected to the handle by a flat key or a spline or a deed, which is highly versatile and easy to disassemble. The valve stem is provided with an anti-blow-out structure.
3. The packing of the valve is braided, a flexible graphite seal ring or a tetrafluoroene seal ring, so that the valve stem can achieve a reliable seal under certain lubrication conditions.
4. As required, the ball valve can be designed as an antistatic structure. A conductive spring is set between the ball and the valve stem, and between the valve stem and the valve body to prevent static ignition and ignition of flammable substances to ensure system safety.
5. Various forms of sealing pairs. According to different working conditions, soft seal, hard seal, fire valve seat and other structures can be selected; below DN150 is a floating ball form, and below DN200 is a fixed ball form.
6. The ball valve seat can be equipped with an auxiliary sealing structure. A grease injection valve is installed at the valve seat and the valve stem, which can be temporarily sealed in an emergency, and the valve stem can be extended according to need to be suitable for laying in the ground.
Five, the main connection size and weight of Q41F stainless steel ball valve :
DN Nominal pass DN
