Eccentric plug valve with elastic seat seal

First, an overview of the elastic seated eccentric plug valve

,是本司引进国际最新的设计理念和工艺技术,自行研发生产的新型 三通旋塞阀 Elastic seat seal eccentric plug valve is a new type of three-way plug valve which is researched and developed by our company by introducing the latest international design concept and technology . The valve's elastic seat seal structure overcomes the defects of traditional plug valves with poor sealing performance and susceptibility to corrosion. The unique centered seal design greatly reduces the operating torque compared to traditional plug valves and minimizes the wear on the sealing surface. , Which prolongs the service life of the valve. Rectangular through-flow abortion, small head loss, and good linearity of flow adjustment. Its excellent sealing and corrosion resistance, ideal operating performance and long service life, suitable for urban sewage, industrial sewage, mud and clear water and other working environments, used as interception or regulating device.

Product characteristics of eccentric plug valve with elastic seat seal

1. The center of the valve sealing surface and the cock rotation axis are designed with an eccentricity. Utilizing the principle of eccentric motion, the plug and valve seat are tightened tighter and tighter when closed to ensure that the valve is tightly sealed; the plug is quickly disengaged from the valve seat when opened, without contact wear, light operation and long valve life.

2. The external high-performance rubber of the nodular cast iron cock skeleton is heat-wrapped as a whole, with good sealing elasticity, and there is no worry about rubber falling off and erosion corrosion.

3. According to different working media, the valve seat can be made of pure nickel, stainless steel or other special materials. It is compounded with the valve body using new surface treatment technology. The combination is firm and can withstand the erosion and corrosion of various media.

4. Straight flow channel makes valve head loss small; valve seat cross section is rectangular, which can obtain linear adjustment of flow; larger rectangular geometry and self-flushing design of the channel are more suitable for sewage or solid impurities .

5. The valve shaft and the plug are integrally cast and formed, with high strength and high torque transmission rigidity, which eliminates the risk of failure of the traditional plug valve pin. The arc-shaped cock is nearly half lighter than the traditional plunger, avoids the flow channel when the valve is fully opened, and has the function of diversion.

6. The valve body is made of high-strength ductile iron, which is more than 20% lighter than traditional plug valves. The short valve body surface distance shortens the residence time of the fluid in the flow channel, and the increase of the fluid flow rate reduces the deposition of impurities.

7. The inside and outside surfaces of the valve are electrostatically sprayed with non-toxic epoxy resin to prevent the valve body from rusting. It is suitable for sewage systems and outdoor, underground and other harsh environments.
