Manual valve overview manual opening and closing a gate valve is ram, ram movement direction and perpendicular to the direction of flow of gate valves can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters. Wedge gate valve disc can be made into a whole, is called a rigid disc, can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc. When selecting the manual valve size is too large or high pressure should adopt gear transmission, conventional can unilaterally to choose a standard handwheel. Manual valve advantages: 1, fluid resistance small, sealing surface Chong brush and erosion by the medium. 2, open and close more effort. 3 the flow direction of medium, not restricted, disturbed flow, reduce the pressure. 4, the structure of the form is simple, short length, good manufacturing technology, wide application scope. Manual valve features: light weight: ontology by senior black ball made from cast iron, compared with traditional gate valves, the weight about 20% ~ 30% reduction in weight, easy installation and maintenance. Flat type brake block: traditional gate often wash the tube in the water after the external objects such as stone, wood, cement, iron filings, sundry sedimentation on the bottom of the valve such as the slots, easy to cause cannot close tightly and form slack phenomenon, at the bottom of the seal of the elastic base seat gate valves with water pipe with flat design, not easy to cause debris deposition, make the flow unimpeded. The overall plastic bags: ram is made of high quality rubber, outsourcing, the whole Europe first-class rubber vulcanization technology make the gate to ensure accurate after vulcanization of geometry size, and rubber and ductile cast gate, then fall off not easily and elastic memory preferred. Jingzhu valve: the valve body adopts precision casting, precise geometry size inside the body to ensure the valve without the need for any finish sealing. Manual flat gate valve features: manual single, two-way slab gate valve has simple structure, light weight, flexible operation, convenient installation, high quality carbon steel manufacturing, its high strength, good performance, long service life. Screw and nut used the soft cover structure, is not affected by the dust. Manual flat gate valve USES: manual single, two-way slab gate valve is suitable for building materials, metallurgy, mining and other industry dust material flow control line. Is an ideal equipment to control dust material flow. Manual flat gate valve working principle: manual single, two-way slab gate valve gate is mainly composed of frame, screw nut, hand wheel, sprocket, hand wheel, Sprocket) Turning, screw with the screw nut and damper for the reciprocating movement of the horizontal direction, the purpose of opening and closing of the valve. Market demand on the market for a long time to use the general phenomenon of a common gate valve is leaking or rust, enterprises introduce European high-tech rubber and valve manufacturing technology of elastic seat seal gate valves to overcome the gate seal, rust and other defects, seal gate valves of the elastic base seat using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, the valve has a light switch, reliable sealing, better elasticity and service life etc. Can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems such as body line used as adjustment and the closure device. All notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
