Abstract
The utility model relates to a fixing device for fixing a pressure valve cover of a compressor, which comprises a compressor body valve port, an outlet valve and the pressure valve cover. The pressure valve cover and the compressor body valve port are fixed through external bolt pins. According to the utility model, as the external bolt pins are adopted for replacing the traditional inner pins, the chute on the compressor body valve port is not required, and a technological treatment step is saved. Moreover, the external bolt pins can facilitate detachment in maintenance. The fixing device furthermore has the following advantages: labor saving, force saving, improved maintenance efficiency and reduced maintenance cost.
Description
Technical field
The utility model 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.
The model utility content
The utility model has designed a kind of fixing device of fixed pressure valve bonnet of compressor, the technical problem of its solution is that interior pin is when extracting out, interior pin is stuck in the chute easily, thereby the inconvenient and effort of taking a lot of work of pin 4 dismounting in causing, also can cause cost of overhaul increase.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of fixing device of fixed pressure valve bonnet of compressor comprises compressor body valve, outlet 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 utility model 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.
Description of drawings

Fig. 2: the fixture structure schematic representation of the utility model fixed pressure valve bonnet of compressor.
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 utility model is described further:
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 utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
