Introduction to Z73H-10 Manual Knife Gate Valve
Z73H-10 manual knife gate valveIt is a type of material that has the advantages of lightweight, simple and compact structure, reliable sealing performance, long service life, and the ability to cut off mediaKnife gate valveThe sealing principle is that when the gate is closed to the bottom, the inclined surface of the gate touches the wedge block on the valve body, causing the gate to tightly adhere to the sealing surface and achieve a sealing effect. The inclined surface at the bottom of the gate has the function of cutting off the medium, making the valve less susceptible to blockage and jamming by the medium. Its structure can be made into hard or soft seals, and can be selected according to customer sealing requirements.
Characteristics of Z73H-10 Manual Knife Gate Valve
1. The adjustable gate sealing surface can scrape off the adhesive on the sealing surface and automatically remove debris;
2. Stainless steel gate can prevent sealing leakage caused by corrosion;
3. The overall stainless steel material can prevent corrosion damage;
4. Short structural length can save raw materials, installation space, and effectively support pipeline strength;
5. Scientific design of upper sealing packing ensures safe, effective, and durable upper sealing;
6. The triangular bracket saves raw materials and ensures the required mechanical properties;
7. The guide block on the valve body enables the gate to move correctly. Squeeze quickly to ensure effective sealing of the gate;
8. The design of reinforcing ribs in the valve body improves its strength;
9. Drive mechanism can be selected arbitrarily;
10. The V-shaped gate can be used for adjustment.
