Description
Technical field
The utility model relates to sealing device for gas cabinet, relates in particular to the seal arrangement of the high-pressure cylinders moulded coal gas holder of a kind of gas storage pressure more than 8KPa.
Background technique
In existing cylinder type gas cabinet, what adopt usually is a kind of seal arrangement of lever compression type.It is by constituting along the black box that is provided with on the gas cabinet axial direction, hold down gag, suspension rod, bearing and piston oil duct etc.Black box comprises sealing canvas, two groups of caulking gum bands, rubber press strip, and connects in aggregates by the caulking gum compressor arm; Hold down gag is made up of members such as pressure strip, connecting plate, wire rope, clamping lever and weights.Wherein the wire rope two ends are fixed on clamping lever and the connecting plate with wire line shoe respectively, and the connecting plate bottom is by push rod and pressed component hinge.The gravity of weight acts on the pressure strip by lever and wire rope, and pressure strip is delivered to power on the caulking gum band, makes the caulking gum band be close to the gas holder inwall and plays the effect that reduces the sealing oil leakage.For making caulking gum band and piston synchronous operation, the upper end of caulking gum compressor arm is connected with piston oil duct ring beam with screw thread, connecting rod.
The shortcoming of above-mentioned sealing device for gas cabinet is:
1, the pressing system complex structure of this device, parts are numerous, cause the space on piston oil duct top narrow and small, make the installation and maintenance difficulty of sealing mechanism.
2, the wire line shoe structure in the lever pressing system, owing to often be given a shock, wire line shoe is loosening easily in the actual fortune of gas cabinet, influence compresses effect.Simultaneously, because an end of wire line shoe is embedded in the sealing oil, be not easy to regulate very much;
3, adopt screwed connection between suspension rod and the caulking gum compressor arm, stress is poor in the gas cabinet actual moving process, causes easily to fracture.
Based on above-mentioned three shortcomings in the present cylinder type thin oil seal gas cabinet, so propose a kind of improved spring compression type sealing device for gas cabinet.
The model utility content
The purpose of this utility model is to be to overcome the shortcoming that the seal arrangement of gas cabinet in the prior art exists, and provides a kind of simple in structure, easy to maintenance, impacting force evenly to reach the high new structure sealing device for gas cabinet of Safety performance.
For realizing described order, the utility model cylinder type sealing device for gas cabinet comprises along the black box that is provided with on the gas cabinet axial direction, hold down gag, suspension rod, bearing and piston oil duct.The upper end of its middle hanger is connected with bearing by bearing pin; Black box comprises sealing canvas, two groups of caulking gum bands, rubber press strip, and constitutes an integral body by the caulking gum compressor arm; Hold down gag comprises pressure strip, and its structure outline is: the piston oil duct is designed to step type, is provided with one and supports shaped steel on the step of piston oil duct, and bearing is fixed on and supports on the shaped steel; The lower end of suspension rod is connected with the pressure strip top of hold down gag by bearing pin; Hold down gag also comprises holddown spring and the sleeve thereof that is located between piston oil ditch wallboard and the pressure strip.
Be respectively equipped with bolt at piston oil ditch wallboard and pressure strip corresponding position, support compression spring and sleeve thereof, holddown spring is placed in the sleeve.
The utility model cylinder type sealing device for gas cabinet compared with prior art has the following advantages:
(1) owing to the piston oil duct with the utility model seal arrangement is designed to step type, so not only can reduce the oil mass of using of piston oil duct, and this step can be used as maintainer's working platform when maintenance;
(2) because hold down gag of the present utility model adopts the holddown spring structure to replace existing weight, lever, wire rope and connecting plate etc. to compress member, structure is greatly simplified.Have the advantage that amount of maintenance is little, metal consumption is few, the space on piston oil duct top is increased, help the installation and the maintenance of black box;
(3) owing to all have holddown spring to compress on every pressure strip of the utility model, it is more even that impacting force lever more of the prior art on the caulking gum band is compressed, and the ability that adapts to gas cabinet side plate Roughness is stronger;
(4) because the hoisting point position of the utility model suspension rod is positioned on the pressure strip, connect alternative existing screwed connection, the force-bearing situation of suspension rod is greatly improved by bearing pin; Simultaneously, make the caulking gum band, form self-tightening power, make that Security is improved in the running because deadweight is adjacent to more on the gas cabinet inwall because hoisting point position is positioned on the pressure strip.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the seal arrangement of the utility model high-pressure cylinders moulded coal gas holder.
Embodiment
With reference to Fig. 1, the seal arrangement of the utility model high-pressure cylinders moulded coal gas holder comprises along the black box that is provided with on the gas cabinet axial direction, hold down gag, suspension rod 3, bearing 2 and piston oil duct 1.Piston oil duct 1 is designed to step type, is provided with one and supports shaped steel 11 on the step of piston oil duct 1, and bearing 2 is fixed on and supports on the shaped steel 11.Black box comprises sealing canvas 7, two groups of caulking gum bands 6, rubber press strip 5, and constitutes an integral body by caulking gum compressor arm 4; Hold down gag comprises pressure strip 10 and is located at holddown spring 9 and sleeve 8 thereof between piston oil duct 1 wallboard and the pressure strip 10, holddown spring 9 is placed in the sleeve 8, be respectively equipped with bolt at piston oil duct 1 wallboard and pressure strip 10 corresponding positions, support compression spring 9 and sleeve 8 thereof.The upper end of suspension rod 3 is connected with bearing 2 by bearing pin, and the lower end of suspension rod is connected with pressure strip 10 tops of hold down gag by bearing pin.
