Abstract
The invention relates to a fixing device of a fixed pressure valve bonnet of a compressor, which comprises a machine body valve opening of the compressor and the pressure valve bonnet, wherein the pressure valve bonnet and the machine body valve opening of the compressor are fixed together by an external bolt pin. In the device, the external bolt pin is used instead of the conventional internal pin, so a chute is not required to be formed on the machine body valve opening of the compressor, and technical processing steps are saved. In addition, the external bolt pin can be conveniently detached during overhaul, so labor and force are saved, the overhaul efficiency is improved, and the overhaul expense is reduced.
Description
Technical field
The present invention relates to a kind of fixing device of chemical field fixed pressure valve bonnet of compressor.
Background technique
Compressor is the common equipment in the chemical field, and one of its function is that the hydrogen in the chemical product is separated with CO (carbon monoxide converter) gas.
As shown in Figure 1, the fixing device of existing pressure valve bonnet is that interior pin 4 is fixed in the chute 5 of compressor body valve 1 inboard, after in unloading process, needing to rotate 30 ° again toward going out to take out.But when interior pin 4 was extracted out, interior pin 4 was stuck in the chute 5 easily, thereby the inconvenient and effort of taking a lot of work of pin 4 dismountings in causing, also can cause cost of overhaul increase.
Summary of the invention
The present invention has designed a kind of fixing device of fixed pressure valve bonnet of compressor, and the technical problem of its solution is an interior pin when extracting out, and interior pin is stuck in the chute easily, thereby the inconvenient and effort of taking a lot of work of pin 4 dismountings in causing, also can cause cost of overhaul increase.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of fixing device of fixed pressure valve bonnet of compressor comprises compressor body valve and pressure valve bonnet, by the outer bolt pin described pressure valve bonnet and described compressor body valve is interfixed.
Further, there is a jackscrew on the described outer bolt pin.
The fixing device of this fixed pressure valve bonnet of compressor is compared with the fixing device of traditional compressor fixed pressure valve bonnet, have following beneficial effect: the present invention is owing to adopt the outer bolt pin to substitute traditional interior pin, make to need not on the compressor body valve, to offer chute again, saved the process treating step.In addition, adopt the outer bolt pin can be when maintenance convenient disassembly, the saving of labor, laborsaving, improve overhaul efficiency, also reduced recondition expense simultaneously.

Fig. 2: the fixture structure schematic representation of fixed pressure valve bonnet of compressor of the present invention.
Description of reference numerals:
1-compressor body valve; The 2-outlet valve; The 3-pressure valve bonnet; Pin in the 4-; The 5-chute; 6-outer bolt pin.
Embodiment
Below in conjunction with Fig. 2, the present invention will be further described:
A kind of fixing device of fixed pressure valve bonnet of compressor comprises compressor body valve 1, outlet valve 2 and pressure valve bonnet 3, by outer bolt pin 6 described pressure valve bonnet 3 is interfixed with described compressor body valve 1.Owing to adopt outer bolt pin 6 to substitute traditional interior pin 4, make to need not on compressor body valve 1, to offer again chute 5, saved the process treating step.In addition, adopt outer bolt pin 6 can be when maintenance convenient disassembly, the saving of labor, laborsaving, improve overhaul efficiency, also reduced recondition expense simultaneously.
There is a jackscrew on the described outer bolt pin 6.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obvious realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
Claims (2)
