  • Patent number: 11067192
    Abstract: A diaphragm valve structure having application in diaphragm valves made completely from fluororesin at an operating temperature of 200° C. The diaphragm valve uses a thermal isolation method that consists of a heat transfer limiting structure and a heat dissipating structure, ensuring rigidity of the gas cylinder structure. The heat transfer limiting structure uses lattice-shaped ribbed plates with horizontal openings, wherein the lattice-shaped ribbed plates and a minimum diameter area of an annular portion are all provided with heat transfer section thickness. The heat dissipating structure consists of a multilayered structure for a preferred external natural cooling, and further using a coolant gas ensuring that the peripheral portion of the diaphragm and gas-tight sealing components on the valve shaft are sufficiently cooled.

  • Patent number: 11035474
    Abstract: A fluoroplastic butterfly valve structure is disclosed that includes an inner metallic butterfly disc and an outer fluoroplastic material enclosing the metallic butterfly disc within a valve body. The butterfly disc has a board-like or cone-like cross section. A fluoroplastic lining has an interference fit with the butterfly disc. A back-up ring is provided between an inner surface of the valve body made of high temperature resistant rubber. The butterfly disc has a complex sealing structure, which includes an unequal-width conical surface and an unequal-width curved surface. The unequal-width curved surface is disposed in a closing direction of the butterfly disc for preventing interference sliding thereof.

  • Patent number: 9746118
    Abstract: A pipe joint structure has a joint body, a fixed ring and a union nut. A flared end of a tube has a conical surface and a tubular surface. The conical surface and tubular surface are connected to a tube connecting portion of the joint body. The union nut is fastened to a locking thread of the tube connecting portion. An interior recess portion of the union nut is coupled with a bulging surface of the fixed ring. The tube is compressed evenly and secured firmly on the joint body.

  • Publication number: 20140319827
    Abstract: A pipe joint structure is used to prevent a tube and pipe joint, especially fluororesin pipe joint from slipping off. The pipe joint comprises a joint body, a fixed ring and a union nut. A jig is used to expand the tube end to become a flared end consisting of a conical surface and a tubular surface, and finally connect it to the conical surface and tubular surface on top of the tube connecting portion of the joint body. When the union nut is fastened to the locking thread of the tube connecting portion, its interior recess portion will couple with the bulging surface of fixed ring to ensure it to stay in a concentric position, thereby allowing the tube wall of sealed surface to be compressed evenly and secured firmly on said pipe joint so to achieve a seal and prevent it from slipping off.
