Detailed Description
The utility model provides a sealed glue and butterfly valve, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right to refer to the attached drawing below and to lift the embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.
Referring to fig. 1 to 3, a butterfly valve includes a housing 210, a valve 220 having one end hinged to the housing 210, and a telescopic assembly 230 for driving the valve 220 to swing, wherein the telescopic assembly 230 is a telescopic cylinder, a hydraulic cylinder or an electric cylinder, the housing 210 has a cavity inside, the housing 210 has two openings 211 communicating with the inside, one of the openings 211 is an air inlet, and the other is an air outlet. The valve 220 is hinged to the edge of the housing 210 near one of the openings 211 at one side, the valve 220 can swing around a hinge point, one end of the telescopic assembly 230 is hinged to the housing 210, the other end of the telescopic assembly 230 is hinged to the valve 220, and the telescopic assembly 230 is connected to the middle of the valve 220 or the side far away from the side hinged to the housing 210, so that when the telescopic assembly 230 is telescopic, the valve 220 can be driven to close or open. Since the valve 220 blocks one of the openings 211 to cut off the airflow path through the interior of the housing 210, the valve 220 is disposed corresponding to one of the openings 211.
The butterfly valve still includes sealed glue 100, sealed glue 100 fixes the border at the opening 211 of shell 210, sealed glue 100 includes adhesive tape body 110, and adhesive tape body 110 wherein one end tip extends to one side has extrusion portion 120, and the adhesive tape body forms transversal personally submitting "gamma" shape structure with extrusion portion 120, and the thickness that extrusion portion 120 kept away from adhesive tape body one end is less than the thickness that is close to adhesive tape body one end, and an terminal surface that extrusion portion 120 kept away from the adhesive tape body is inclined plane 121. The extrusion part 120 of the sealant is arranged at one end of the adhesive tape body facing the valve 220, and the extrusion part 120 of the sealant is arranged at one side of the adhesive tape body facing the middle part of the opening 211.
In the aforesaid, through set up extrusion portion 120 in adhesive tape body 110 one end, and the adhesive tape body forms transversal personally submitting "gamma" shape structure and extrusion portion 120 and the thickness that extrusion portion 120 kept away from adhesive tape body one end is less than the thickness that is close to adhesive tape body one end, make when closing valve 220, valve 220 is earlier with sealed extrusion portion 120 butt of gluing, because extrusion portion 120 arranges the adhesive tape body outside in, consequently warp to sealed outside when the pressurized warp, make more laborsaving when closing valve 220, and because sealed thickness that adhesive tape body one end was kept away from to sealed extrusion portion is less than the thickness that is close to adhesive tape body one end, make sealed extrusion portion deflection of gluing each big, improve the butterfly valve leakproofness.
For the installation convenience of sealed glue, shell 210 is equipped with the recess (not marking in the figure, the sealed position of installing of fig. 3) at opening 211 border, and the adhesive tape body is kept away from extrusion portion 120 one end and is inlayed in this recess, and sealed glue is installed on shell 210 through the mode of inlaying and adorning, because sealed glue has the shrinkage, consequently makes simple to operate.
Preferably, the rubber strip body is provided with an installation part 130 at one end far away from the extrusion part 120, the rubber strip body, the extrusion part 120 and the installation part 130 form a structure with a Z-shaped cross section, and the installation part 130 is embedded in the groove. Because installation department 130 and extrusion portion 120 extend in the both sides of adhesive tape body, when extrusion portion 120 received the extrusion, installation department 130 can warp to the upset direction, consequently makes installation department 130 more closely with the recess is inside, improves sealed effect.
In a preferred embodiment, the thickness of the mounting portion 130 away from one end of the adhesive tape body is smaller than the thickness of the mounting portion close to one end of the adhesive tape body, so that the sealant can be conveniently pressed into the groove, and when the sealant valve 220 is extruded, the mounting portion 130 is also easier to deform and tightly adhere to the side wall of the groove.
In practical application, the protrusion 240 and the pressing plate 250 are also arranged on the edge of the opening 211 through the shell 210, the groove is formed between the protrusion 240 and the pressing plate 250, one side of the sealant abuts against the protrusion 240, one side of the sealant, which is far away from the protrusion 240, abuts against the pressing plate 250, and the mounting part 130 of the sealant is arranged between the pressing plate 250 and the shell 210, so that the sealant is pressed on the shell 210 by the pressing plate 250, and the sealant is fixed more firmly.
Wherein, clamp plate 250 passes through modes such as screw detachable to be fixed on shell 210, when sealed glue of installation, earlier sealed glue cover in protruding 240 departments, then install clamp plate 250, realize sealed fixed of gluing, simple structure, simple to operate.
In the above, the sealant strip body, the extruding portion 120 and the mounting portion 130 are integrally formed.
The sealant is not limited and can be applied to a butterfly valve, and can also be applied to equipment with a turnover type access door, namely, the sealant is installed on an access hole of the equipment, and the access door is abutted to the sealant when closed.
