Abstract
The utility model discloses a gas tank sealing device, which comprises a hammer mechanism fixed on a piston. The front end of a lever of the hammer mechanism is connected with the upper end corner of an angular connecting plate through a wire rope; a support bar is arranged between the lower end corner of the angular connecting plate and a bottom plate; a connecting supporting plate, a rubber scraping plate, a rubber backing plate and an angle steel pressure plate are fixed on the bottom plate; and the lower end of the wire rope is connected with the upper end corner of the angular connecting plate through a cable shackle. The cable shackle is a U-shaped connecting ring and is provided with a pin rod at the front end thereof. The rubber scraping plate is provided with a V-shaped end in contact with a tank wall plate. The front ends of the connecting supporting plate and the angle steel pressure plate are encapsulated with metal pieces. The gas tank sealing device can ensure the safe use of a gas tank, and effectively prolongs the service life of the gas tank.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of seal arrangement that is used on the large-scale gas cabinet of gasholder station.
Background technique
The pressure great majority of sealing surface are applied by many groups spring pressurized in the sealing device for gas cabinet at home, can reduce sealing effect along with weakening of spring power in long-term using process.Prescribed time-limit when therefore the seal life weak point does not reach design.Prior art changes original spring attachment into heavy hammer type and compresses, and can guarantee the long-term pressurized uniformity of seal arrangement so effectively.But owing to adopt heavy hammer type to compress, connection part must connect with wire rope up and down.Wire rope is in the utilization process, and its present Placement is with 0.3 on top
#The shaped steel collar is strengthened protective gear, but the bottom wire rope is just wrapped up on connecting plate (connecting plate thickness 16mm), and then fixes with wire line shoe Y-10 type.Up and down the position each 3 the cover.Seal arrangement in running up and down along with piston and cabinet wallboard spacing in continuous variation, bottom wire rope and connecting plate rub mutually, bottom wire rope appearance is is in use over a long time worn and torn, at last until wire cable rupture.Cause the leakage of oil of equipment seal arrangement to exceed standard, equipment accident so far occurs and stop using.In addition, the rubber seal scraper plate is a parallel strip in the existing seal arrangement, and wearing and tearing in use are big, can cause poorly sealed.Connect supporting plate and angle steel pressing plate installation back and cabinet wallboard face place in the seal arrangement for wrapping up in the body metallic state.After the long-term use of rubber seal scraper plate, bigger loss is arranged, in case after wearing away 22mm, connecting supporting plate and angle steel pressing plate metalwork just has meeting and the friction of cabinet wallboard, produces spark when metalwork rubs mutually, huge potential safety hazard will occur.
The model utility content
At above-mentioned the problems of the prior art, the purpose of this utility model is to propose the sealing device for gas cabinet of a kind of long service life, no potential safety hazard.
The utility model is that the technological scheme that its purpose of realization is taked is: a kind of sealing device for gas cabinet, be connected with wire rope between the lever front end that comprises the weight mechanism that is fixed on the piston, weight mechanism and the dihedral connecting plate upper end hole, be provided with strut between stomidium and the base plate under the dihedral connecting plate, connect supporting plate, rubber flap, rubber mat plate and angle steel pressing plate and be fixed on the base plate, it is characterized in that described wire rope lower end is connected by the rigging shackle with described dihedral connecting plate upper end hole.
Described rigging shackle is a U font connecting ring, and front end is provided with a pin rod.
The contacted end of described rubber flap and cabinet wallboard is the V font.
The front end of described connection supporting plate and described angle steel pressing plate is the metalwork encapsulate.
The beneficial effects of the utility model: guarantee that equipment is safe in utilization, prolonged the working life of product effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of Fig. 1;
Fig. 3 is a rigging shackle schematic representation.
Embodiment
Referring to Fig. 1-3, the utility model is that weight mechanism 11 is fixed on the piston 13 to the improvement of existing weight compression type sealing device for gas cabinet.The upper end of wire rope 9 is connected with the lever front end of weight mechanism 11, and the lower end of wire rope 9 is connected with dihedral connecting plate 12 upper corners by rigging shackle 8.Rigging shackle 8 is a U font connecting ring, and front end is provided with a pin rod.The front end pin rod of ring is inserted in the dihedral connecting plate 12 upper corners attachment holes, and this hole changes φ 22mm into by φ 19mm.The tail end of ring, promptly the semicircle end is connected with wire rope 9.Rigging shackle 8 is used for strengthening protection wire rope 9.In use wire rope 9 unloads the slick and sly friction of clasp with rigging, so wire rope phenomenon of rupture can not occur.Also be provided with rope cramp 10 on the wire rope 9.
Be provided with strut 15 between dihedral connecting plate angle, 12 lower end and the base plate 16.Connection supporting plate 7 and angle steel pressing plate 4 are clipped in the middle rubber flap 6, rubber mat plate 5 and are fixed on the base plate 16, and suspension rod 2 is hung these rubber seals on boom support 1.Suspension rod 2 is a jointing type, and the lower end is provided with connecting sleeve 3.Rubber flap 6 is the V font with cabinet wallboard 14 contacted ends.The front end of described connection supporting plate 7 and described angle steel pressing plate 4 is the metalwork encapsulate.Encapsulate thickness is 2mm, adopts high abrasion glue.
V font rubber seal scraper plate divides upper and lower each 2 layers of installation, forms " W " shape attitude respectively.In use sealing area forms strip, guarantees to be sealed in the distortion of cabinet wallboard and uses as usual greatly or under the rough situation of cabinet wallboard.
Supporting plate and angle steel pressing plate are installed the back to the utility model and cabinet wallboard face place changes into metalwork encapsulate state for wrapping up in the body metallic state connecting.Because after the long-term use of rubber seal scraper plate bigger loss is arranged,, produce spark when metalwork rubs mutually and major safety risks will occur once after wearing away 22mm, metalwork just has meeting and the friction of cabinet wallboard.Can eliminate this hidden danger behind the metalwork encapsulate and guarantee the equipment safety in utilization, prolong the working life of product effectively.
