Ciri-ciri strukturinjap pagar

Injap pagar has the characteristics of small fluid resistance, applicable pressure and temperature range, etc. It is one of the most commonly used cut-off valves, used to cut off or connect the medium in the pipeline. The shrinkage of the diameter can reduce the size of the parts, reduce the force required for opening and closing, and expand the application range of the parts. But after the diameter shrinks. The fluid resistance loss increases. Low-pressure injap pagars in China generally use cast iron materials. Cast iron injap pagars often have serious problems such as freezing and cracking of the valve body and falling off of the gate. The carbon steel stem of the cast iron injap pagarmudah berkarat, kualiti gasket pembungkusan buruk, dan kebocoran dalaman dan luaran serius.

1. Keseluruhan enkapsulasi getah: Gerbang menggunakan getah berkualiti tinggi untuk keseluruhan getah dalaman dan luaran. Teknologi pemvulkanan getah membolehkan gerbang tervulkan untuk memastikan dimensi geometri yang tepat, dan getah dan pintu cor mulur dihubungkan dengan kuat, tidak mudah jatuh dan elastik.

2. Tempat duduk gerbang rata: tradisionalinjap pagar often silt in the groove at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, sundries, etc. after the pipe is flushed with water, which can easily cause water leakage due to inability to close tightly. Phenomenon, the bottom of the elastic seat seal injap pagar adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unimpeded.

3. Badan injap pemutus ketepatan: Badan injap menggunakan pemutus ketepatan, dan dimensi geometri yang tepat menjadikan bahagian dalam badan injap tanpa pemprosesan halus untuk memastikan kedap injap.
