Background technique
Middle body and filler are one of important components of compressor, play the role of installing filler, sealing gas.It is now wide
The general middle body used, filling-material structure are Dan Zhongti and single filler, the structure be by one group of packing seal compressor shaft to gas
Body pressure, if gas leakage occurs for compressor, it will cause very serious consequence.
Body has the disadvantages that when the gas in compressor is easily leakage and explosion hazard gases in existing compressor, warp
After single packing seal, it is extremely easy to appear the case where gas leaks, until leading to the generation of safety accident.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of new type compressor proposed
It is double in body structures.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of double middle body structures of new type compressor, it is characterised in that: including cylinder body, cylinder, crankcase, set in cylinder body
A piston rod is set, the both ends of piston rod are cooperatively connected with the crosshead in the piston and crankcase in cylinder respectively, in piston
It is socketed main stuffing box on bar, fills filler in main stuffing box, is cooperatively connected body in one first in the side of cylinder, the
One main filler end cap is set in vivo in one, main filler end cap and cylinder are cooperatively connected, it is socketed secondary stuffing box on the piston rod,
Filler is filled in secondary stuffing box, body is cooperatively connected body in one second far from the side of cylinder in first, the body in second
Interior that a secondary filler end cap is arranged, body is cooperatively connected in secondary filler end cap and first, and the side of body and crankcase cooperate in second
Connection.
Preferably, the piston rod sequentially passes through the main stuffing box, body in first, main filler end cap, secondary stuffing box, the
Body, secondary filler end cap in two.
Preferably, the main stuffing box, main filler end cap, secondary stuffing box, secondary filler end cap are coaxially arranged.
Preferably, the junction of body 7 in the cylinder 2 and described first, the pair filler is arranged in the main stuffing box 5
The junction of body 10 in body 7 and second in described first is arranged in box 9.
Preferably, the filler is slidably matched with the piston rod.
Utility model has the advantages that the utility model structure is reliable, and it is easy to use, into two-stage packing seal and two excessively
Body pressure release in grade, so that the utility model is for easily leaking, the gas of explosive etc. has better sealing.
Detailed description of the invention
Fig. 1 is the basic structure schematic diagram of the utility model；
Fig. 2 is the portion the A enlarged drawing of Fig. 1；
Fig. 3 is the basic structure schematic diagram of body in existing compressor.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, double middle body structures of a kind of new type compressor provided by the utility model, including cylinder body 1,
Cylinder 2, crankcase 3, in cylinder body 1 place a piston rod 4, the both ends of piston rod 4 respectively with the piston and crankshaft in cylinder 2
Crosshead in case 3 is cooperatively connected, and piston rod 4 uses the prior art with the connection type of piston and crosshead.
Cover main stuffing box 5 on piston rod 4, the setting of main stuffing box 5, for preventing the gas in cylinder 2 from leaking out,
Each main stuffing box 5 is stuck in the junction of body 7 in the cylinder 2 and described first, fills in each main stuffing box 5
Filler 6, the piston rod 4 slide on the filler 6, and filler 6 can be divided into sealing ring, block ring and subtract according to different role
Pressure ring etc. connects body 7 in one first in the side of cylinder 2, and body 7 is used to place main stuffing box 5 in first, while to cylinder 2
The air venting leaked out, the side of cylinder 2 by bolt with first in body 7 connect, the placement one in body 7 in first
Main filler end cap 8 digs four through-holes on main filler end cap 8, digs four close to the side of main filler end cap 8 in cylinder 2
Threaded hole, bolt pass through through-hole and threaded hole corresponding with through-hole, and main filler end cap 8 is fixed on the cylinder 2, while can also
Main stuffing box 5 is closed, the gas in cylinder 2 is prevented to flow into first in body 7 by main stuffing box 5.
Secondary stuffing box 9 is covered on piston rod 4, the setting of secondary stuffing box 9 leaks for sealing from cylinder 2 into body 7 in first
Gas, prevent the gas leaked out from continuing to spread, it is described pair stuffing box 9 be placed in described first body in body 7 and second
Filler 6 is filled in 10 junction in secondary stuffing box 9, and the piston rod 4 slides on the filler 6, body 7 in first
Side far from cylinder 2 connects body 10 in one second, a secondary filler end cap 11 is placed in second in body 10, in secondary filler
Four through-holes are dug on end cap 11, dig four threaded holes in first on body 7, and bolt passes through through-hole and corresponding with through-hole
Secondary filler end cap 11 is fixed in first on body 7 by threaded hole, and the side of body 10 is connect with crankcase 3 in second, cylinder 2,
Connection type in one in body 7, second between body 10 and crankcase 3 uses the prior art, and the piston rod 4 sequentially passes through described
Body 7 in main stuffing box 5, first, main filler end cap 8, body 10, secondary filler end cap 11 in secondary stuffing box 9, second, the main filler
