It is also reciprocal compressor stuffing box structure more common at present disclosed in above-mentioned patent, but for the stuffing box of above-mentioned form, generally when logical cooling water, adopt water channel grinding-in stuffing box, adopt whole circle seal with O ring stuffing box, detachable maintaining difficulty is larger.
Summary of the invention
Object of the present invention is exactly to overcome the defect that above-mentioned prior art exists and the water channel welding type stuffing box providing a kind of and reduce field-strip difficulty, save time, raise the efficiency.
Object of the present invention can be achieved through the following technical solutions:
A kind of water channel welding type stuffing box, sheathed on the piston rod between two flanges, stuffing box comprises compact arranged stuffing box, and is arranged on the packing ring between adjacent stuffing box;
Described stuffing box is hollow disc shape body, water annulus is offered in stuffing box inside, the inlet channel be connected with water annulus and water outlet water channel is respectively equipped with in the left and right sides of stuffing box, the inlet channel of the stuffing box of adjacent two docks with water outlet water channel, makes to form the cyclic water channel for cooling water circulation between all stuffing boxes;
The inlet channel of the stuffing boxes of adjacent two and the joint of water outlet water channel are provided with sealing O shape enclose, make between the inlet channel of adjacent stuffing box and water outlet water channel with seal with O ring;
Described stuffing box offers an annular groove, described packing ring is located in annular groove, makes to seal between piston rod and stuffing box.
Wherein, described water annulus is arranged perpendicular to piston rod, and described inlet channel and water outlet water channel are all parallel to piston rod and arrange, and inlet channel and water outlet water channel lay respectively at the both sides up and down of piston rod.
Wherein, offer annular water tank in the side of stuffing box, dividing plate is set at the opening of annular water tank, dividing plate and annular water tank opening welded seal, form the weld seam closed, make annular water tank inside form airtight water annulus.
Wherein, the opening of described inlet channel and water outlet water channel is opened in the left and right sides of stuffing box respectively, described inlet channel or water outlet water channel are communicated with by inner radial water channel with between water annulus, and the described end of radial water channel is connected with the face seal of stuffing box.
Wherein, offer seal groove in the periphery of the water outlet water channel of stuffing box, described O shape circle is embedded in seal groove.
Packing ring of the present invention uses 3 lobe band springs to tighten up formula structure.
When stuffing box of the present invention uses, the movement locus of cooling water is as follows:
First cooling water enters in the inlet channel of first stuffing box from the cooling water intake be opened in flange, then the water annulus of first stuffing box is flow through, flow out from the water outlet water channel of first stuffing box, enter the inlet channel of second stuffing box, then flow out from the water outlet water channel of second stuffing box after cooling water flows through the water annulus of second stuffing box, motion mode according to this, cooling water finally flows out from the water outlet water channel of last stuffing box, flowed out by the coolant outlet be arranged on flange, complete the circulation of cooling water.
Because inlet channel and water outlet water channel lay respectively at the both sides up and down of piston rod, and be communicated with by water annulus between inlet channel with water outlet water channel, make the movement locus of cooling water in stuffing box be similar to waveform track.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1) original stuffing box all adopts whole circle seal ring, and present invention eliminates the whole circle seal ring of stuffing box, only arranges little O shape circle at the water outlet water channel place of stuffing box, which reduces the grinding work of surface of contact between adjacent stuffing box;
(2) vibrational power flow of the present invention makes to overhaul convenient disassembly, when packing ring is changed in maintenance, each stuffing box is only needed to pull out piecewise, new packing ring is changed by damaging after the packing ring lost efficacy is dismantled, because it is with little O shape circle that the water channel between different stuffing box connects sealing, not original cover whole circle O shape circle on the piston rod, just can install easily.
Accompanying drawing explanation
