I. Structural features of elastic seated gate valve:
闸阀 普遍存在着漏水或生锈现象,开维喜阀门集团引进欧洲高科技橡胶及阀门制造技术所生产的弹性座封闸阀,克服了一般闸阀密封不良,生锈等缺陷,弹性座封闸阀利用弹性闸板产生微量弹性变形的补偿作用达到良好的密封效果,该阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命等显著优点。 General gate valves used in the market have been leaking or rusting for a long time. Kaiweixi Valve Group introduced European high-tech rubber and valve manufacturing technology to produce elastic seated gate valves, which overcomes the defects of general gate valves such as poor sealing and rust The elastic seat sealing gate valve uses the compensation effect of the slight elastic deformation generated by the elastic gate plate to achieve a good sealing effect. The valve has significant advantages such as light switching, reliable sealing, good elastic memory and long service life. Can be widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, power, marine, metallurgy, energy systems and other body pipelines as regulating and shut-off devices.
Second, the characteristics of the elastic seat gate valve:
Light weight: the body is made of high-grade nodular cast iron, which is about 20% ~ 30% lighter than traditional gate valves, and is easy to install and maintain.
Flat-bottom gate seat: Traditional gate valves are often deposited in grooves at the bottom of the valve due to foreign objects such as stones, wood blocks, cement, iron filings, and debris after washing the pipes, which can cause leaks that cannot be closed tightly. The bottom of the elastic seat sealing gate valve adopts the same flat bottom design as the water pipe machine, which is not easy to cause debris deposition and make the fluid flow unobstructed.
Integral rubber encapsulation: The gate is made of high-quality rubber for overall internal and external coating. European first-class rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions, and the rubber and ductile cast sluice are firmly attached, which is not easy to fall off Good elastic memory. water
Precision casting valve body: The valve body is precision-casting, and the precise geometric size allows the valve body to be sealed without any finishing.

产品概述 Product Overview

Except for the advantages of elastic seated gate valve, it can be opened and closed quickly and reliably. Therefore, it is often used in fire protection and industrial systems. It is generally installed at a higher position from the ground.
