Hard sealed gate valveThe opening and closing component of the gate valve is the gate valve, and the direction of movement of the gate valve is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the two sealing surfaces of the commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high.
Lightweight: The body is made of ductile black cast iron, which reduces the weight by about 20% to 30% compared to traditional gate valves, and is easy to install and maintain.
Flat bottomed gate seat: Traditional gate valves often accumulate in the groove at the bottom of the valve due to external objects such as stones, wooden blocks, cement, iron filings, and debris after flushing the pipe, which can easily cause leakage due to inability to close tightly. The bottom of the elastic seat sealed gate valve adopts the same flat bottomed design as the water pipe machine, which is not easy to cause debris accumulation and allows fluid to flow smoothly.
Overall rubber coating: The gate is made of high-quality rubber for both internal and external coating. The rubber vulcanization technology ensures the geometric dimensions of the vulcanized gate, and the rubber is firmly attached to the ductile iron gate, making it difficult to fall off and having good elastic memory.
Precision cast valve body: The valve body is made of precision casting, and its geometric dimensions ensure the sealing of the valve without any precision machining inside the valve body.
