Title: Butterfly valve preventing dew condensation
Inventor: KAMEZAWA JIRO
IPC: F16K51/00
Filed: 1989-12-25
Abstract: PURPOSE:To prevent dew condensation and to dispense with heat insulating covering by having a valve body, a valve stem sleeve and an attaching plate, and heat insulating covering the whole surface of a metallic shell structure formed smaller than the specified dimension of a butterfly valve with heat insulating synthetic resin material. CONSTITUTION:A butterfly valve 10 is composed of a valve body 11, a valve stem sleeve 16, a inner shell structure 23 formed of metallic material used for aluminium die casting in one body with an attaching plate 17, and an adiabatic covering layer 24 covering the whole surface of a shell structure 23 to required thickness. The valve body 11, the valve stem sleeve 16 and the attaching plate 17 are decided in their shapes on the shell structure 23, which is formed smaller than the specified dimensions of the butterfly valve 10 by the thickness of the heat insulating covering layer 24, which is made of synthetic resin such as hard vinyl chrolide. Thus a pipe attaching work can dispense with special heat insulating treatment, and therefore becomes simple.

Abstract: PROBLEM TO BE SOLVED: To prevent opening of the meshes of an air permeable packing. SOLUTION: The whole of an air permeable packing 13d formed of a mesh material 17 is formed in a long square shape. Namely, the single mesh material 17 is folded and two edges are overlapped with each other, the overlap part 18 and the mesh material 17 on the side situated opposite to the overlap part 18 are spot-welded to each other. Thus, the overlap part 18 of the air permeable packing 13d has a first weld part 19 and the air permeable packing 13d on the side positioned opposite to the first weld part 19 has a second weld part 20. The second weld part 20 is arranged in a position corresponding to the tip edge of the draining part 16 of a switch case 2.  In this constitution, when the tip edge of the draining part 16 is forced into pressure contact with the second weld part 20, since wires of which the mesh material 17 of the second weld part 20 consists are welded to each other, relative displacement in a position hardly occurs. Thereby, the meshes of the mesh material 17 of the second weld part 20 are prevented from opening.

Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an alignment free electric connector which has high reliability of electric connection and has high flexibility to relative positional dislocation by forming contact parts by folding them back, and relatively thinning a plate thickness of a flexible part. SOLUTION: A contact 14 extends to a flexible part 14c composed of four U-shaped bending parts from contact parts 14a, and is also formed in the shape of extending to tine parts 14b. The flexible part 14c acts to keep electric connection between both housings even if a first housing 11 and a second housing 12 of a cap connector 10 are relatively displaced in the arrow B-B' direction. Since the contact parts are formed by folding them back, antinomic demands of flexibility to positional dislocation and reliability of electric connection are reconciled. For example, the contact parts are formed by folding a metallic plate back, and a plate thickness of the metallic plate can be reduced, and flexibility is increased, and flexibility to positional dislocation can be enhanced.
