Abstract
The utility model discloses a splitting surface milling flute gas-leakage prevention device of an oxygen compressor, comprising a lower air cylinder body (1), an upper cover (2) connected with the lower air cylinder body (1), a bolt hole (3) arranged on the lower air cylinder body (1) and the upper cover (2) for fixedly closing and connecting the lower air cylinder body (1) and the upper cover (2), a sealing groove (4) arranged on the sealing surface of the upper cover (2), and a sealing rubber strip (5) mounted in the sealing groove (4). In the utility model, on the basis of the sealing device in prior art, the sealing groove is arranged on the sealing surface of the sealing cover, an anti-oxidation and anticorrosion strip is arranged in the sealing groove, the sealing property of the sealing device can be well enhanced by utilizing the contraction elasticity of the strip; therefore, the splitting surface milling flute gas-leakage prevention device has simple structure, can well improve the sealing effect of the splitting surface of the oxygen compressor, and reduces the gas-leakage overhauling frequency of the splitting surface of the oxygen compressor; particularly, the utility model discloses the splitting surface milling flute gas-leakage prevention device of the oxygen compressor.
Description
Technical field
The utility model relates to a kind of seal arrangement of anti-gas-leak, is specially oxygen compressor split groove milling anti-gas-leak device.
Background technique
The oxygen compressor mid-separate surface seal of being used is in the market all adopted usually and is opened sealing cover, is coated with on the sealing surface with water glass (sodium silicate), and bolt in addition can realize sealing then.Because cylinder adopts cast steel case, is the horizonally split structure, split neither needs through precision machining, does not also allow the pad of packing into, so only be coated with bath of glass (sodium silicate) bolt in addition then.
Such seal arrangement, normal no gas leak phenomenon during trial run, but normal operation will leak air in the time of bimestrial approximately, owing to be hyperbaric oxygen in the cylinder, when hyperbaric oxygen because seal arrangement poorly sealed, and by sealing surface after the oxygen compressor internal leakage, for the environment of working is not only a kind of pollution, a kind of especially potential risk when running into naked light, at any time all might breaking out of fire etc. has a strong impact on ordinary production even can cause the danger of tremendous economic loss.
Therefore, how can better improve the effect of this oxygen compressor mid-separate surface seal, reduce the repair rate of equipment, improve the working efficiency of oxygen compressor, be a kind of urgent problem.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, it is a kind of not only simple in structure that the utility model provides, and can be good at prolonging the sealing effect of oxygen compressor split, reduction is too high because of the repair rate that the gas leakage of oxygen compressor split causes, and is specially a kind of oxygen compressor split groove milling anti-gas-leak device
The purpose of this utility model is achieved in that
Oxygen compressor split groove milling anti-gas-leak device, comprise cylinder lower cylinder body (1) and the loam cake (2) that is connected with cylinder lower cylinder body (1), and be arranged on and be used for fixing the bolt hole (3) that sealing is connected cylinder lower cylinder body (1) and loam cake (2) on lower cylinder body (1) and the loam cake (2), the sealing surface of loam cake (2) is provided with seal groove (4), and sealing joint strip (5) is installed in the seal groove (4).
Seal groove (4) is arranged between bolt hole (3) and the oxygen cylinder (6).
The adhesive tape (5) that is arranged in the seal groove (4) adopts anti-oxidant, corrosion-resistant material, and before not with bolt, is arranged at the sealing surface that adhesive tape (5) in the seal groove (4) is higher than loam cake (2).
Beneficial effect: the utility model adopts on the basis of original seal arrangement, the sealing surface of sealing cover is provided with seal groove, adhesive tape anti-oxidant, corrosion-resistant material is installed in the groove, utilize the contraction elasticity of adhesive tape, can better increase the sealing of seal arrangement, therefore, it is a kind of not only simple in structure that the utility model provides, and can be good at improving the sealing effect of oxygen compressor split, reduce the repair rate of oxygen compressor split gas leakage, be specially a kind of oxygen compressor split groove milling anti-gas-leak seal arrangement.
Description of drawings
Fig. 1 is the split structural representation of the loam cake in the utility model;
Fig. 2 is the split structural representation of the lower cylinder in the utility model;
Fig. 3 is the generalized section a of A-A` among Fig. 1;
Fig. 4 is the generalized section b of A-A` among Fig. 1;
Among the figure be: cylinder lower cylinder body (1), loam cake (2), bolt hole (3), seal groove (4), adhesive tape (5), oxygen cylinder (6);
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Oxygen compressor split groove milling anti-gas-leak device, comprise cylinder lower cylinder body (1) and the loam cake (2) that is connected with cylinder lower cylinder body (1), and be arranged on and be used for fixing the bolt hole (3) that sealing is connected cylinder lower cylinder body (1) and loam cake (2) on cylinder lower cylinder body (1) and the loam cake (2), the sealing surface of loam cake (2) is provided with seal groove (4), because oxygen compressor is a steel casting structure, volume and weight all is very huge and heavy, do not utilize and move and processing, then volume is less to be positioned at the loam cake (2) of cylinder body top, weight is lighter, utilize light dismounting and processing, so seal groove (4) is arranged on the sealing surface of loam cake (2), seal groove is equipped with adhesive tape in (4).
Seal groove (4) is arranged between bolt hole (3) and the oxygen cylinder (6).
As shown in Figure 4, the adhesive tape (5) that is arranged in the seal groove (4) adopts anti-oxidant, corrosion-resistant material, and before not with bolt, be arranged at adhesive tape (5) in the seal groove (4) and be higher than the sealing surface of loam cake (2), be the convergent-divergent that has made full use of adhesive tape (5) like this, when loam cake seals mutually with lower cylinder, this moment, bolt can be undertaken fixedly connected by bolt hole (3), this is under the pretightening force of bolt, adhesive tape (5) can be compressed in the seal groove (4), externally expand fully simultaneously, played good seal action.
The utility model adopts on the basis of original seal arrangement, the sealing surface of loam cake is provided with seal groove, adhesive tape anti-oxidant, corrosion-resistant material is installed in the groove, utilize the contraction elasticity of adhesive tape, can better increase the sealing of seal arrangement, therefore, it is a kind of not only simple in structure that the utility model provides, and can be good at improving the sealing effect of oxygen compressor split, reduce the repair rate of oxygen compressor split gas leakage, be specially a kind of oxygen compressor split and mill seal groove anti-gas-leak device.
Above embodiment only is used to illustrate preferred implementation of the present utility model; but the utility model is not limited to above-mentioned mode of execution; in the ken that described field those of ordinary skill is possessed; any modification of being done within spirit of the present utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technological scheme scope that the utility model asks for protection.
