Bevel gear pair clamp type knife gate valve

Productoverview:
PZ573H/Y series Bevel gear clamping type knife gate valve Pneumatic drive, clamp connection, rod parallel rigid single gate and valve seat sealing surface for the hard alloy with PTFE, the model is divided into: PZ573X, PZ573H, PZ573F, PZ573Y, nominal pressure PN10~16, the valve body is made of carbon steel, stainless steel (PZ573H-10C/16C) (PZ573F-10P/16P, PZ573Y-10P/16P), has the function of discharging gate valve. PZ573H bevel gear knife type gate valve with circular channel design, the upper blades installed in PTFE, scraper, wear-resistant poly resin or flanging cone made of wear-resistant cast iron containing Ni installed on the inlet end of the knife gate valve, multiple rinse mouth is arranged on the valve body around. Processed into the bottom plate blade knife, high degree of finish, to ensure a good seal.
Two, structure principle:
PZ573H/Y series Bevel gear clamping type knife gate valve Is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, the manual knife gate valve can be fully open and fully closed, can not be adjusted and the throttle. There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge, the wedge angle varies with the valve parameters, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of the deviation, make up the sealing surface angle in the process, the gate is called the flexible knife gate valve is closed, the sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the knife gate valve is sealed by force, that the valve is closed, to rely on external pressure to force the gate to the seat, to ensure the sealing surface of the seal of the valve in the pipe shall be installed horizontally.
Three, Bevel gear clamping type knife gate valve Uses and characteristics:
1, the circular channel design, processed into the bottom plate blade knife, high degree of finish, to ensure a good seal.
2, the upper blades installed in PTFE, scraper, can prevent dust scratch gravel and other substances into the stuffing box.
Wear 3, poly resin hem pyramidal or Ni made of wear-resistant cast iron is installed in the inlet end of the knife gate valve, can prevent particles directly scour on the seal, which can improve the working condition, prolong life.
4, according to the needs of multiple washing opening is arranged on the valve body around, the direct use of air, steam or water to wash, to prevent the gradual accumulation of sediment, especially suitable for the type of fluid difficult.
5, gear holder type knife gate valve has compact design and small occupied space, light weight, easy installation, wear and anti blocking measures to perfect, easy maintenance, long service life. Widely meet the paper and pulp industry, industrial waste water and city sewage treatment, chemical plant, fly ash processing, bulk materials, food and beverage industry requirements and working conditions under harsh environmental conditions slow down.

Six, Bevel gear clamping type knife gate valve The main performance specifications:

Seven, gear holder type knife type valve main parts material:

Eight, the main parts of external and connecting dimensions:

Nine, ordering:
1, the bevel gear knife gate valve product name and model of bevel gear knife type valve caliber the bevel gear knife gate valve with the attachment so that we use the use of medium pressure gear knife type valve you the correct selection of bevel gear knife type gate valve of the temperature.
2, if it has been selected by the design unit Wei bevel gear knife type valve type, press the bevel gear knife type valve type directly to our sales department order.
3, the occasion is very important when using more complex or the environment when you try to provide design drawings and detailed parameters by our Zhongwei control expert audit checks for you.
Ten, inspection (unloading) notice:
1, carefully controlled products and order (the bevel gear clamping type knife type valve) is the same, and there is no breakage of packing box.
2, choose suitable methods and tools, to prevent deformation or damage of the product; our company attaches great importance to the service, in order to achieve customer satisfaction product standards we have with the customer side by side, share experiences, information, commitment, goal, in cooperation between the development of excellent products.
