Description

The manual relief arrangement of piston compressor
Technical field
The utility model belongs to piston compressor technical field, is specifically related to the manual relief arrangement of a kind of piston compressor.
Background technique
Piston compressor is in operation, because front system loading changes the Load Regulation that need carry out compressor self.But the original remote loads controlling device of compressor, because of control system complexity, design the unreasonable unloading effect that is difficult to realize, and if redesign and manufacture remote loads controlling device, exist and manufacture and design the shortcoming that the cycle is long, cost is high.Because weight adjustment device cannot move, therefore can cause start-stop car frequently to the compressor moving, the security of operation of compressor and Economy be can not be guaranteed.
Model utility content
The purpose of this utility model is to provide a kind of piston compressor manual relief arrangement, has solved the shortcoming that existing weight adjustment device is difficult to realize piston compressor Load Regulation.
The technological scheme that the utility model adopts is: the manual relief arrangement of piston compressor, comprise the valve gap with inner hollow cavity, on valve gap, be provided with stuffing box, the bottom of stuffing box is positioned at the hollow cavity inside of valve gap, the top of stuffing box has the packing cavity of inner hollow, the inside of stuffing box is provided with threaded valve rod, one end of valve rod passes the bottom of stuffing box and is positioned at the hollow cavity of valve gap, the other end of valve rod extends packing cavity outside, the surrounding of the valve rod of packing cavity inside is filled with graphite and soaks the filling body that tetrafluoro forms, the upper surface of filling body is provided with packing press ring, packing press ring is linked on valve rod, the upper surface of packing press ring is provided with Gland, Gland is also linked on valve rod, Gland is connected with the outer wall of stuffing box.
Feature of the present utility model is also:
Between valve gap and stuffing box, being provided with sealing gasket seals.
Stuffing box is secured by bolts in the upper surface of valve gap.
Gland adopts and is threaded with the outer wall of stuffing box.
The beneficial effects of the utility model are: the manual relief arrangement of piston compressor of the present utility model has solved the shortcoming that existing weight adjustment device is difficult to realize piston compressor Load Regulation, the utility model apparatus structure is simple, be easy to make, cheap and handling safety is reliable, can realize the Load Regulation to piston compressor, and not changing on the integrally-built basis of piston compressor, guarantee that device uses and equipment is easy to improve compressor operating rate under the prerequisite of maintenance, on average monthly many operations approximately 22 hours.
Brief description of the drawings
Fig. 1 is the structural representation of the manual relief arrangement of piston compressor of the present utility model.
In figure, 1. valve rod, 2. Gland, 3. packing press ring, 4. filling body, 5. stuffing box, 6. sealing gasket, 7. valve gap.
Embodiment
Below in conjunction with embodiment, the utility model is elaborated.
The structure of the manual relief arrangement of piston compressor that the utility model provides as shown in Figure 1, comprise the valve gap 7 with inner hollow cavity, on valve gap 7, be provided with stuffing box 5, the bottom of stuffing box 5 is positioned at the hollow cavity inside of valve gap 7, the top of stuffing box 5 has the packing cavity 8 of inner hollow, the inside of stuffing box 5 is provided with threaded valve rod 1, one end of valve rod 1 passes the bottom of stuffing box 5 and is positioned at the hollow cavity of valve gap 7, the other end of valve rod 1 extends packing cavity 8 outsides, the surrounding of the valve rod 1 of packing cavity 8 inside is filled with graphite and soaks the filling body 4 that tetrafluoro forms, the upper surface of filling body 4 is provided with packing press ring 3, packing press ring 3 is linked on valve rod 1, the upper surface of packing press ring 3 is provided with Gland 2, Gland 2 is also linked on valve rod 1, Gland 2 is connected with the outer wall of stuffing box 5.
Between valve gap 7 and stuffing box 5, being provided with sealing gasket 6 seals.
Stuffing box 5 is secured by bolts in the upper surface of valve gap 7.
Gland 2 adopts and is threaded with the outer wall of stuffing box 5.
In the hollow cavity of valve gap 7 inside, be also provided with and press fork, the bottom of stuffing box 5 is touched and is connected with pressure fork-join.
Valve rod 1, Gland 2, packing press ring 3, stuffing box 5 and the valve gap of the manual relief arrangement of piston compressor of the present utility model are steel matter, and sealing gasket adopts red copper material.
The valve gap 7 of the manual relief arrangement of piston compressor of the present utility model is arranged on to the ingress of piston compressor, the utility model makes it move vertically the load of regulating piston formula compressor by rotary valve rod 1, in the time that compressor need to unload, reverse clockwise valve rod 1 and make its pressure fork of depressing inlet one-way valve, realize compressor load unloading; In the time that compressor needs load restoration, reverse counterclockwise spring that valve rod makes inlet one-way valve place and back down and press fork, realize load on.
By the way, the manual relief arrangement of piston compressor of the present utility model has solved the shortcoming that existing weight adjustment device is difficult to realize piston compressor Load Regulation, the utility model apparatus structure is simple, be easy to make, cheap and handling safety is reliable, can realize the Load Regulation to piston compressor, and not changing on the integrally-built basis of piston compressor, guarantee that device is normal and use and equipment is easy to improve compressor operating rate under the prerequisite of maintenance, on average monthly many operations approximately 22 hours.
