Product Overview
Integrated bidirectional soft-seal knife gate valve is a high-performance valve capable of bidirectional pressure bearing. Adopting a bidirectional sealing design, it achieves reliable sealing and pressure resistance under bidirectional medium flow. The precision cast integrated structure can withstand high pressure difference, negative pressure difference and other working conditions.
■ 产品概述
一体式双向软密封刀型闸阀是一种高性能双向承压的阀门。采用双向密封设计,能够实现介质双向流动时的可靠密封及承压。精密铸造一体式结构可承受高压差,负压差等。
Structural Features
Structural Design: The valve adopts a bidirectional sealing structure to deliver reliable sealing regardless of the medium flow direction.
Sealing Design: A U-shaped sealing strip is installed at the bottom of the valve body cavity, with steel wire lining inside the strip to guarantee long-term stable operation under high pressure difference working conditions.
Sealing Principle: The U-shaped sealing strip fits tightly between the gate plate and valve seat to realize bidirectional sealing. The elastic design of the sealing strip can compensate tiny deviations on the sealing surface to guarantee excellent sealing performance.
Wear-resistant Materials: The sealing surface is generally made of wear-resistant rubber, polyurethane and other materials, featuring outstanding wear resistance and corrosion resistance.
Recess-free design: No grooves inside the valve body to prevent medium retention and lower clogging risks.
Full bore flow passage: Unobstructed internal flow path enables smooth medium flow and reduces pressure loss.
■结构特点
•结构设计:阀门采用双向密封结构,无论介质流向如何,都能实现可靠的密封。
•密封设计:阀体中腔底部设有U型密封条,密封条内衬钢丝,确保在高压差工况下长期稳定工作。
•密封原理:闸板与阀座之间的U型密封条紧密贴合,实现双向密封。密封条的弹性设计能够补偿密封面的微小偏差,确保密封性能。
