Product introduction:
Z41F46 flange fluorine-lined gate valve is a special gate valve newly developed by our factory suitable for corrosive media. Suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, and various organic acids and strong oxidants at -50ºC~150ºC. FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases and liquid media. Use on the pipeline. It is widely used in water plants, power plants, chemicals, food, papermaking, medicine and other industries.
working principle:
Z41F46 flange fluorine-lined gate valve uses wedge-shaped gates sealed on both sides to connect or cut off the medium in the pipeline. The wedge gate valve does not allow a small amount of opening to be used as a throttling device in the pipeline to avoid erosion due to high-speed flow And accelerate the damage of the sealing surface. The sealing pair adopted by our company is FEP or other material combination, with low friction coefficient and low opening and closing torque; packing adopts PTFE standard packing, which has good sealing performance and convenient maintenance and replacement; with elastic gate, it can compensate gate seal and valve The wedge angle between the sealing surfaces of the seat is deviated, the degree of agreement is good, and the sealing effect is ideal.
Features:
1. Light weight: The body is made of nodular black cast iron, which is about 20%~30% lighter than the traditional gate valve, and is easy to install and maintain.
2. Overall encapsulation: The rubber used in the gate is integrated inside and outside. European rubber vulcanization technology enables the vulcanized gate to ensure the geometric size, and the rubber and the ductile cast gate are firmly connected, not easy to fall off and elastic memory good.
3. Precision casting valve body: The valve body adopts precision casting, and its geometrical dimensions make the inside of the valve body without any precision machining to ensure the sealing of the valve.
4. Flat-bottomed gate seat: The traditional gate valve often deposits in the groove at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, debris, etc. Phenomenon, the bottom of the elastic seat seal gate valve adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unimpeded.
