一.Product Introduction
The transmission mode of PZ673X-150LB American standard pneumatic slurry gate valve is pneumatic, with a wafer connection form. The valve stem is a rigid single gate plate with a rising stem parallel. The sealing surface material of the valve seat is synthetic rubber, with a nominal pressure of PN6~PN10. The valve body material is gray cast iron. The gate valve (slurry valve) continuously digests and absorbs the advanced characteristics of similar product structures and manufacturing processes at home and abroad during production and application. Continuously improving the technological content of the product, starting from some technical details, has improved the comprehensive performance of the valve. This product can achieve automatic control of the opening and closing positions by using accessories such as solenoid valves. Users can choose according to their actual needs. The main body adopts casting, cast steel, stainless steel, etc. The diameter ranges from DN50-DN1200. The product is widely used in fields such as chemical industry, coal, sugar production, sewage, paper making, etc. It is an ideal sealing valve. Especially suitable for regulating and throttling on pipelines in the paper industry. This valve adopts a fully circular channel design, and the bottom of the blade is processed into a blade, with high smoothness, ensuring good sealing. A hard polytetrafluoroethylene and a scraper are installed on the upper end of the blade to prevent abrasive substances such as dust and gravel from entering the packing box. The wear-resistant folding cone made of polyester or Ni containing wear-resistant cast iron is installed at the inlet end of the knife gate valve, which can prevent particle materials from directly flushing onto the seal, thereby improving working conditions and extending service life. As needed, multiple flushing ports can be installed around the valve body, which can be directly flushed with air, steam, or water to prevent the gradual accumulation of sediment. It is particularly suitable for fluids that are difficult to input.
二.Product Features
-
- Adopting a wafer type structure, it has a small volume and light weight.
- A completely open channel with low flow resistance can prevent the medium from depositing inside the valve.
- The newly developed U-shaped sealing ring can ensure the good sealing performance of the valve.
- The external sealing of the gate is achieved by embedding an elastic sealing strip inside the valve body, which can be adjusted with the help of screws and pressure plates.
