Abstract
The utility model provides a stuffing box with a positioning ring and a water seal bolt and aims to solve the problems that according to the normally used stuffing boxes with water cooling and the normally used stuffing boxes with most stuffing cases arranged in a connecting cylinder, a positioning rod leaks water, stuffing materials rub a piston rod due to sinking, the leakage amount is large and the like. The stuffing box with the positioning ring and the water seal belt is characterized in that the stuffing box with the positioning ring and the water seal bolt, the stuffing box is provided with cooling water and parts of the stuffing cases are arranged in the connecting cylinder. The water seal bolt is connected with three stuffing boxes close to an air cylinder in series to form a first entirety, the positioning rod is connected with the first entirety, the rest of the stuffing boxes and a stuffing flange in series to form a second entirety, and the positioning ring is arranged between two stuffing boxes which are arranged in the connecting pipe in an exposing mode. The stuffing box with the positioning ring and the water seal bolt has the advantages of solving the problems that the positioning rod of the stuffing boxes leaks water, the stuffing cases rub the piston rod due to the sinking, the leakage amount is large and the like, and greatly improving reliability of utilization of the stuffing boxes.
Description
Technical field
The utility model relates to the stuffing box that a kind of compressor uses, and is the stuffing box that places extend neck with cooling water and part stuffing box specifically.
Background technique
In modern industry, along with the large scale development take coal, oil, rock gas as the chemical enterprise of raw material, large reciprocating compressor has obtained broader applications, and tolerance and the pressure of its processing also greatly increase.In order to satisfy the requirement of compressor " zero leakage ", usually need between the cylinder block of compressor and piston rod, establish seal arrangement, also be stuffing box.
The stuffing box of at present compressor use comprises: some packing seal ring member; The bowl-type of placing the packing seal ring member part that spaces is stuffing box; Filler flange; The positioning rod that all group of stuffing box bunch is used for together mounting or dismounting and location; And oiling, fill nitrogen, gas leakage is reclaimed and cooling water gateway joint.When the exhaust pressure of cylinder is higher, also need be provided with restrictor ring in the cylinder side of stuffing box.For revealing the filler of putting in extend neck with cooling water and part stuffing box, in its actual use the situation that the positioning rod nut leaks and stuffing box sinks that filler flange covers often appears.Trace it to its cause be positioning rod and the bowl-type of placing filler space matching gap between the part excessive due to, if the gap is reduced just can not realize correct installation.
Leaking of stuffing box causes corrosion to the important parts around it easily.Filler sinks filler is contacted with the piston rod single face, makes the top friction aggravation of piston rod, and underclearance increases, and there is the problem of gas leakage in this stuffing box, causes easily inflammable and explosive, poisonous and hazardous medium to leak in a large number, has potential safety hazard.
The model utility content
For solving the problems of the technologies described above, of the present utility modelly be to provide a kind of stuffing box with positioning ring and water shutoff bolt.
Concrete scheme of the present utility model is: it comprises stuffing box, filler flange and stuffing box, it is characterized in that: said stuffing box is the stuffing box that places extend neck with cooling water and part stuffing box.The water shutoff bolt will be unified into the first integral body near three stuffing box bunchs of cylinder side, and positioning rod is connected into the first integral body, remaining stuffing box and filler flange the second integral body, thereby avoids passing the seepy question that cooling water passage causes because of positioning rod; Between two stuffing boxes in being placed on extend neck a positioning ring is set, stuffing box is radially accurately located, prevent that the stuffing box that causes because of alignment error and other reasons from sinking, the rapid friction that piston rod is produced causes the problem revealed.
Compared with prior art, the beneficial effects of the utility model are: the problem such as solved effectively that the stuffing box positioning rod leaks, stuffing box sinking friction piston bar and leakage rate are large, improved the reliability that stuffing box uses greatly.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, said stuffing box is the stuffing box 9 that places extend neck with cooling water and part stuffing box.Water shutoff bolt 8 will be connected into the first integral body near three stuffing boxes 1,2,3 of cylinder side, and positioning rod 4 is connected into the first integral body, remaining stuffing box and filler flange the second integral body, thereby avoids passing the seepy question that cooling water passage causes because of positioning rod; Between two stuffing boxes 5 in being placed on extend neck and 7 positioning ring 6 is set, stuffing box is radially accurately located, prevent from sinking because of the stuffing box that alignment error and other reasons cause, the rapid friction that piston rod is produced causes the problem revealed.
