38results about How to "Increase the sealing structure" patented technology

A valve apparatus is comprised of a solenoid valve, a manual valve, a pressure relief device, a check valve, an excess flow shut-off device, and a temperature sensor. The temperature sensor is arranged inside the tank in an ambient atmosphere. The sealing member is prevented from falling off from the recess by a floating seal structure. The sealing effectiveness is improved by employing a double seal configuration and also by a smooth surface roughness. A high pressure seal structure is presented. The improved pressure relief device design for 75 MPa application has been presented.

The invention relates to the technical field of a temperature controller, specifically a waterproof temperature sensitive controller. The controller comprises a shell of which upper end is opened; a temperature sensing cover is covered on the upper end opening of the shell; two electric terminals are arranged on the base plate of the shell; a tray is fixedly arranged in the upper end opening of the shell; a thermosensitive sheet resisting against the temperature sensing cover is arranged on the upper end surface of the tray; a waterproof structure is arranged between the outer edge of the upper end of the shell and the temperature sensing cover; the lower end of the shell stretches downwards along the base plate and is equipped with a packaging ring; the lower ends of the electric terminals are connected with leads; the leads pass through threading openings and are leaded out transversely; and sealing glue is filled in the inner cavity of the packaging ring. The controller provided by the invention has the advantages that the structure is rational; a sealing structure except the temperature controller body is prevented from being added; a flatted design is realized through adoption of an inverse Y-shaped linkage moment arm and a flexible tongue piece; the tray and the outer edge of the shell match and are assembled integrally; the height of the integral structure can be effectively compressed; the layout is compact; the assembly is convenient; the reaction is sensitive; the assembly efficiency can be improved; and the integral cost can be reduced.

The invention relates to a radiating and anti-carbon powder device of a collector ring component of a motor of a wound rotor, which belongs to the technical field of manufacture of motors. The device comprises a terminal box, a support of the collector ring component, electric brushes, conductive rings, a leading wire, an insulating sleeve, a brush rod, collector rings, a fan, an insulating pipe,conductive rods, a fan cover, a sleeve and a shaft, wherein, the collector rings are sheathed on the sleeve and mutually insulated with the sleeve, each collector ring is provided with the conductiverod and linked with the leading wire of the rotor, the fan is arranged on the flange part of the sleeve, the whole sleeve is sheathed on the shaft, three electric brushes are arranged on three conductive rings, the conductive rings are arranged on the brush rod, the brush rod is arranged on the support, the support is arranged on an end cover of the motor, an air inlet is formed at the upper part, the fan cover is arranged on the outer side of the end part, and an air outlet is formed at the lower part. The device solves the short circuit problem caused by heating of the collector rings and carbon powder, improves the conductive performance of the collector rings of the motor, prolongs the service life of the collector rings of the motor, reduces the using cost of the motor and improves the reliability of operation of the motor.

The invention provides a zipper bag sealing structure which comprises a bag body, a male buckle zipper structure and a female buckle zipper structure, wherein the bag body is provided with a first inner side wall and a second inner side wall, and one end of the first inner side wall and one end of the second inner side wall are connected with each other to form a butt fusion area; the male bucklezipper structure is arranged on the first inner side wall and is provided with two opposite male buckle end parts; the female buckle zipper structure is arranged on the second inner side wall, is disconnected from or connected with the male buckle zipper structure under the action of external force, and is provided with two opposite female buckle end parts; and each female buckle end part and thecorresponding male buckle end part which are adjacent to each other are mutually fused into a whole so that a butt fusion section which is integrally fused and is positioned in the butt fusion area can be formed, thus, the sealing performance is enhanced, contents in a zipper bag can be preserved for a long time, and the purposes of preventing the contents from going bad and from being damped canbe achieved.

The invention discloses a handle of an oil-immersed fuse used for an American-type box substation, which can improve the sealing performance and increase the creepage distance. The oil-immersed fuse comprises a cylindrical base, a fuse holder and a fuse element, wherein the base comprises an outer shell, and two conducting rings and a mounting base which are arranged in the outer shell at intervals; the fuse holder comprises the handle, and two contact pins connected with two ends of the fuse element respectively; one of the two contact pins is connected with the handle; the handle comprises a connecting rod, a cover, a knob, a sealing structure and a sealing ring which are connected with one another in turn; the sealing structure is arranged on the connecting rod, is close to one end of the cover, is a section of cylinder which is formed by extending the surface of the connecting rod in the radial direction; the peripheral surface of the cylinder is provided with an annular groove inthe radial direction; the diameter of the sealing structure is matched with the inside diameter of the base; the sealing ring is embedded in the groove of the sealing structure; and the cross sectionof the connecting rod of the handle is round, and a plurality of layers of umbrella ridges are protruded on the peripheral surface of the handle in the radial direction at intervals along the length direction.
