    Bevel gear dark plate knife gate valves are suitable for pipelines with suspended particles, pulp, s…

    Description:
    A brief introduction:
    PZ573H series <strong> gear dark plate knife gate valve</strong> applies with suspended particles and fibrous material pulp, sewage, coal slurry, slag cement mixture medium pipeline, fiber material can be cut by blade shaped gate to cut off the medium. The body does not actually exist in the chamber, the gate side of the guide groove and the lifting lug bottom pressed on the seat, to achieve high medium sealing, can choose O shaped sealing seat bi-directional seal. According to the drive into manual knife gate valve, pneumatic knife gate valve, electric knife type valve.
    Two, structure principle:
    PZ573H series Bevel gear knife gate valve in the dark 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 knife gate valve in the dark 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.
