Double side remake door
Double side remake door

The buckle door is a check valve product, which is mainly installed at the end of the drainage pipe to avoid the ingress of external water. Raw materials are divided into stainless steel, carbon steel, cast iron and other materials.

This product is a one-way valve installed at the outlet of the riverside drainage pipe. When the tide level of the river is higher than the outlet pipe and the pressure is greater than the pressure in the pipe, the shutter panel is automatically closed to prevent the river tide from flowing back into the drainage pipe. This product is a product developed by our company. The product is subject to the Q/TF-B2771 industry technical standard; the experiment is carried out according to the GB/T13927 experimental requirements; the nominal pressure (PN) of the equipment: 0.25-1.6Mpa; the nominal diameter (DN): 200-2000mm.

Second, use

The buckle door is suitable for various pipes and water channels of water supply and drainage and sewage treatment projects for overflow and check. It can also be used as a variety of shaft covers. It is only used for one-way water outlets.

3. Structural features:

The buckle has the function of unidirectional opening and reverse closing of the flow channel. The valve cover of the buckle door uses the balance of its own counterweight to actively open or close the door leaf under the action of water flow, or slightly open or close the door leaf with a slight external force; the buckle door cover is equipped with a pull ring to pull it. The open view point around this cover should be greater than 60 degrees, without jamming, and the switch should be free and sensitive. When the buckle door is partially immersed in water, the internal pressure of the pipeline is relatively large, and the reverse pressure is small, the buckle door allows part of the leakage. When the water pressure increases, the buckle door will actively seal.
