Introduction of PZL43 Sprocket Wafer Type Knife Gate Valve


I. Overview of PZL43 Sprocket Wafer Type Knife Gate Valve

链轮对夹式刀型闸 阀闸板选用奥氏体不锈钢,耐腐性能大大提高,可有效的防止由于闸板腐蚀引起的密封泄漏其闸板具有剪切功能,可刮除密封面上的粘着物,自动清除杂物。 PZL43 sprocket wafer knife gate valve is made of austenitic stainless steel, which greatly improves the corrosion resistance, which can effectively prevent the leakage of the seal due to the corrosion of the gate. The gate has a shear function and can scrape off the sealing surface. Adhesives automatically remove debris. Stainless steel gates prevent seal leakage due to corrosion. The ultra-short structure length saves material and can greatly reduce the overall weight of the piping system. It occupies less effective space, can effectively support the strength of the pipeline, and can reduce the possibility of pipeline vibration.

Second, PZL43 sprocket wafer type gate valve

适用于带有悬浮颗粒、纤维材料的纸浆、污水、煤浆、灰渣水泥混合物等介质的管道,靠可以切割纤维材料的刀刃型闸板来切断这些介质。 Elastic seated gate valve is suitable for pipelines with suspended particles, fiber materials such as pulp, sewage, coal slurry, ash slag cement mixture, etc. These blades are cut by knife-type gates that can cut fiber materials. The valve body does not actually have a cavity. The gate is lifted and lowered in the side guide groove, and is pressed against the valve seat by the lug at the bottom. If high medium tightness is required, an O-shaped valve seat can be used to achieve Two-way seal.

Third, PZL43 sprocket wafer type gate valve precautions and characteristics

The opening and closing part of the knife gate valve is a gate. The movement direction of the gate is perpendicular to the fluid direction. The knife gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters, usually 50. The gate of a wedge knife gate valve can be made into a whole, called Rigid gate; it can also be made into a gate that can produce slight deformation to improve its processability and make up for the deviation of the sealing surface angle during processing.This type of gate is called an elastic gate when the knife gate valve is closed, the sealing surface It can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most knife gate valves are forced to seal, that is, When the valve is closed, it is necessary to force the gate to the valve seat by external force to ensure the tightness of the sealing surface. This type of valve should generally be installed horizontally in the pipeline.

Fourth, the main standard of PZL43 sprocket wafer type gate valve

(1) GB12232-89 "Universal valve flange-linked iron gate valve"

(2) GB12234-89 "Universal valve flange and butt welded steel gate valve"
