soft-sealing gate valve can be divided into ( Non-rising stem, sanctioned) Gate valve, its components for the gate opening and closing. The direction of flow direction and the vertical of the gate. Gate valves can only be fully open and close, can't adjust and throttling. Taking non-rising stem of the elastic base seat of the sealing valve, the use of the entire valve seal deformation compensation function, can achieve good sealing effect, overcomes the general gate valve sealing, leakage, rusty phenomenon, save installation space more effectively. Soft seat soft-sealing gate valve is widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, gold processing, energy systems and so on the regulation of fluid pipeline and closing device. Scope of application: soft seat soft-sealing gate valve is particularly suited to the potable water system, food, pharmaceutical industry, industrial water supply and drainage and sewage treatment, gas, natural gas, and other fields, soft seat gate valves can also be widely used in tap water, sewage, construction and other fields. Petroleum, chemical, food, medicine, textile, electric power, ships, gold processing, energy systems such as automobile body line. Structure features: flat base soft-sealing gate valve design as a whole through the flow channel at the bottom of the pool, the equivalent of a binding concave cavity structure of straight pipe. It has small flow resistance, ensure smooth flow of water is not easy to pile up sundry, the media do not cause secondary pollution. Stem nut and gate structure to ensure the enough degrees of freedom, opening and closing flexible, and accessibility. Sealing ring online replace special shaft seal structure, when fully open, sealing ring can change online, without the need for water. Reliable seal between the valve stem and the top of the top sealing adopts 'within 3 2' five o-ring. Compared with the traditional gate packing seal structure, compact structure and reliable sealing, the friction resistance is reduced greatly. Corrosion resistance of shell inside and outside surface ( Ductile iron QT500 - 7) Electrostatic spraying epoxy powder. Uniform coating and firm, not iron. The middle cavity connecting bolt at the top of the sealant is applied to insulate the bolt contact with the environment, to prevent corrosion. Food grade sanitary requirements gate valve cavity spray epoxy resin powder, Germany DVGW standard, far higher than the requirements of GB/T 17219; The stem and stem nut inside is stainless steel or bronze, not affected by water corrosion; Rubber coated to meet T he drinking water hygiene standards. Additional features can provide valve opening, directly buried underground, anti-theft lock control instructions and other additional features.
