Description
Technical field
A kind of compressor packing letter leakage testing device of the utility model, belongs to compressor service technique field.
Background technology
Piston compressor airtight and watertight padding, will produce substantial amounts of frictional heat in the running, according to the difference of pressure release, often
Primary seal filler is made of some sealing rings, is divided in several stuffing-boxes, and the both ends of the surface of stuffing-box are refined by grinding machine,
Surface roughness is rigid seal without gasket between 0.4 or so, each stuffing-box, and cooling water is by one group of packing box flange lower part of outermost
Into cooling water cavity, and curve is turned back and is finally flowed out from the top of packing box flange, if the sealing surface between two stuffing-boxes
There is groove mark or there is foreign matter to will result in the gas leakage in cylinder water inlet or cylinder, it is also possible to cause in airtight and watertight padding cooling water
It is disconnected, the consequences such as airtight and watertight padding are burnt, so the leak test after stuffing-box maintenance is especially important, existing service kit does not have special pin
To the leak test instrument of compressor packing letter.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided one kind simulation stuffing-box working environment, to filling out
Expect that letter carries out the leakage testing device of leak test.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of compressor packing letter leak test
Device, including stuffing-box, stuffing-box are sleeved on leak test bar, and leak test bar one end is packing box flange, and the leak test bar other end is set
There is the ring flange of corresponding packing box flange, be connected between ring flange and packing box flange by screw rod, screw rod is provided at both ends with tightly
Gu nut, for fastening stuffing-box.
Plug is provided with the water return outlet of the stuffing-box, for ensuring that water will not be from water return outlet when doing leak test test
Outflow influences the judgement to stuffing-box leak source.
The screw rod is no less than 2.
The utility model has the advantages that compared with prior art.
1st, the piston rod in stuffing-box real work is simulated by leak test bar, by being set between ring flange and packing box flange
Screw rod is put, stuffing-box is fastened by the nut at screw rod both ends, realizes reliable sealing, simple in structure, economical and efficient.
The 2nd, plug is set on stuffing-box water return outlet, the external recirculated water of water inlet, can realize stuffing-box with convenience and high-efficiency
Leak test before assembling, improves the repair quality of stuffing-box, and the stuffing-box of failure is handled in time, prevents from being assembled to
Occur the phenomenon for burning packing seal after compressor, improve repair quality, avoid and do over again.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
1 it is stuffing-box in figure, 2 be leak test bar, 3 be ring flange, 4 be screw rod, 5 be clamp nut, 6 be water inlet, 7 is back
The mouth of a river, 8 are plug.
Embodiment
As shown in Figure 1, a kind of compressor packing letter leakage testing device of the utility model, including stuffing-box 1, stuffing-box 1 are set with
On leak test bar 2,2 one end of leak test bar is 1 flange of stuffing-box, and 2 other end of leak test bar is provided with the flange of corresponding 1 flange of stuffing-box
Disk 3, is connected between ring flange 3 and 1 flange of stuffing-box by screw rod 4, and screw rod 4 is provided at both ends with clamp nut 5, stuffing-box 1
Plug 8 is provided with water return outlet 7, screw rod 4 is no less than 2.
When the utility model is used, adjusting stuffing-box 1 by clamp nut 5, connect and follow at the water inlet 6 of stuffing-box
Ring water pipeline, water return outlet 7 are blocked with plug 8, are carried out leak test test, can be installed on stuffing-box 1 at leak test rear without exception
On compressor.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
On the premise of various changes can be made.
