Description
Technical field:
A kind of clearance controlling device is applicable to the adjusting of the split type compressor air-discharging amount of high-speed high-power, relates to the technical field that petroleum gas large-scale compressor air displacement is regulated automatic controller.
Background technique:
In the prior art, in order to regulate the air displacement of Reciprocting piston compressor, make it reach best working condition, one of method of regulating is exactly to change clearance volume, traditional regulating method is to adopt manual operating method, rotate the adjusting handle of compression cylinder cylinder head end joint clearance device, when rotating adjusting handle, the piston that can drive in the clearance device moves forward and backward, and the clearance volume of cylinder is increased or reduces, thereby the clearance of compressor operating cylinder is increased or reduce, to reach the purpose of regulating air displacement, but there is shortcoming in prior art, and manually-operable labor intensity is big, can not regulate according to the variation of operating mode in good time.
Summary of the invention:
The purpose of this utility model is the shortcoming at prior art, utilizes Pneumatic Control Technology, designs a kind ofly can realize self-regulating clearance controlling device.
The utility model is achieved in that the utility model comprises clearance cylinder, ram and Sealing, it is characterized in that: the clearance cylinder comprises clearance cylinder body 3, clearance piston 1 and piston rod 2, clearance piston 1 is connected as one by piston rod 2 and power piston 9, and clearance piston 1 is contained in the clearance cylinder body 3;
Ram comprises power cylinder body 10, power piston 9, three-way diverter valve 4, and described three-way diverter valve 4 is arranged on the two ends of actuating cylinder body 10, and power piston 9 is loaded in the actuating cylinder body 10;
Be provided with the packing box 14 and the filler 15 of Sealing between described power cylinder body 10 and clearance cylinder body 3, Sealing is connected with clearance cylinder body 3 by bolt 13;
Be provided with front-seat gas port 12 and rear exhaust port 8 in the lower end of described power cylinder body 10, play the effect of the gas of getting rid of power cylinder body 10 medium power pistons 9 two ends;
Described actuating cylinder cylinder head end is connected with cylinder cap 6, plays the effect of closed power cylinder cylinder head end.
Working procedure is: when needs are adjusted clearance, according to adjusting the big or little of clearance, to the three-way diverter valve 4 input pressurized gass that are arranged on actuating cylinder body 10 two ends, in the time of need turning clearance down, pressurized gas passes through the tracheae line 5 on three-way diverter valve 4 the right to the rear end of power piston 9 transporting compressed gas, propulsion power piston 9 travels forward, and also moves forward and backward thereby drive clearance piston 1, realizes turning down the purpose of clearance; When needing the big clearance of bar, pressurized gas is by the front end transporting compressed gas of the tracheae alignment power piston 9 on three-way diverter valve 4 left sides, propulsion power piston 9 moves backward, thereby driving clearance piston 1 also moves backward, realize transferring the purpose of big clearance, by such adjustment, reach the increase of adjusting clearance cylinder volume or the purpose that reduces, change the volume of compressor operating cylinder;
Effect of the present utility model is: by the automatic control of actuating cylinder, the clearance piston is moved forward and backward, reach automatic control and adjust the increase of clearance cylinder volume or the purpose that reduces, alleviated operator's labor intensity, owing to be automatic control, therefore can regulate the size of clearance volume in good time according to the variation of working conditions of compressor, change the air displacement of compressor.
Description of drawings:
Fig. 1 is that of the present utility model cuing open shown structural representation.
Specific implementation method:
Provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model comprises clearance cylinder, ram and Sealing, the clearance cylinder comprises clearance cylinder body 3, clearance piston 1 and piston rod 2, clearance piston 1 and power piston 9 are connected as one by nut 7 by piston rod 2, clearance piston 1 is contained in the clearance cylinder body 3, and O RunddichtringO and plastic piston ring 16 working medium with hermetic compressor is housed on the clearance outside piston;
Ram comprises power cylinder body 10, power piston 9, three-way diverter valve 4, power piston 9 is loaded in the actuating cylinder body 10, respectively have a through hole that feeds in the power cylinder body 10 at the two ends on power cylinder body 10 tops, in through hole, be provided with air pipe 5, between two air pipes, be provided with three-way diverter valve 4, the outer end of three-way diverter valve 4 connects compressed gas source, in order to get rid of the gas that enters power cylinder body 10 medium power pistons 9 two ends, be provided with front-seat gas port 12 and rear exhaust port 8 in the lower end of power cylinder body 10, cylinder head for closed power cylinder 10, form the closed cylinder chamber, cylinder head end at actuating cylinder 10 is connected with cylinder cap 6, and the pressurized air of seal ring 11 with the packed-piston two ends is housed on power piston 9;
In order to prevent to leak, the gas in sealing clearance cylinder body 3 and the power cylinder body 10 is provided with packing box 14 and filler 15 between power cylinder body 10 and clearance cylinder body 3, and Sealing is connected with clearance cylinder body 3 by bolt 13;
During operation, the three-way diverter valve 4 that power cylinder body 10 tops are provided with feeds pressurized gas by any end of air pipe 5 to actuating cylinder 10 two ends at two ends, when needs reduce clearance volume, tracheae line 5 by three-way diverter valve 4 the right feeds pressurized gas to actuating cylinder 10 the right, power piston 9 is moved to the left side, and clearance piston 1 also moves to the left side under the drive of piston rod 2, realizes reducing the purpose of clearance volume, at this moment, the air that exists in the actuating cylinder left end is discharged through front-seat gas port 12; When needs increase clearance volume, by turning to of three-way diverter valve 4, by the air pipe on three-way diverter valve 4 left sides when power cylinder body 10 left sides feed pressurized air, power piston 9 is moved to the right, under the drive of piston rod 2, clearance piston 1 also moves to the right, realizes increasing the purpose of clearance volume, at this moment, the air that exists in the right-hand member of actuating cylinder is discharged through rear exhaust port 8; The utility model by pressurized air as power source, automatic moving forward and backward of operation control clearance piston, thus increase or reduce clearance volume, can alleviate manipulation strength effectively, regulate the size of clearance volume, change the air displacement of compressor; In the accompanying drawing, figure number 7 is fastening nuts of power piston 9.
