Abstract
A multi-stage pressure cylinder for outputting pressure or power under the action of pressure gas or liquid is an improvement on single-stage one in that cylinder tube is divided into n subtubes by (n-1) isolating rings, where n is equal to or greater than 2, and n pistons on a same mandrel are respectively in own subtube. A forward inlet is made on right end cover and a reverse inlet on left end cover. A forward and a reverse inlets are respectively arranged at each side of isolating ring. Its advantages include high output pressure or power, small size and easy manufacture.
Description
The present invention relates to a kind of under pressed gas or liquid effects the multi-stage pressure cylinder of delivery pressure or power.
Usually, our seen pressure cylinder all is the single stage of pressure cylinder, it includes cylinder sleeve, place on the cylinder sleeve axis and pass mandrel and the axle sleeve and the piston of end cap, the driving source (gas pressure or fluid pressure) that this single stage of pressure cylinder owing to be subjected to is acted on greatly less, the influence of volume and manufacturing process factors such as (as the sealings of withstand voltage, the relevant component of cylinder sleeve), the pressure or the power of its output are little.
Patent Office of the People's Republic of China's Patent Gazette for Utility Models disclosed a title on September 18th, 1991 and has been: two double-acting cylinder cascaded structures, application number is: 90219565.4 utility application, this is a kind of structure of two single-stage cylinders series connection, breather check valve door and outgassing nonreturn valve door all are housed on the front end and back end of high pressure air cylinder body, breather check valve and outgassing nonreturn valve all are housed on the front end and back end of low pressure gas cylinder body, piston rod passes the coupling part of two single-stage cylinders, high pressure piston and low pressure piston are installed on the piston rod, when the gas of high pressure piston and low pressure piston one side is compressed, the air intake valve of this side is closed, the valve open of giving vent to anger, and the gas of opposite side is inflated, the air intake valve of this side is opened, the valve closing of giving vent to anger, reciprocating motion of the pistons, two valves of giving vent to anger in each cylinder are alternately opened, and pressurized gas is transported to the next stage compression set by gas outlet.This double-acting cylinder cascaded structure is used on the big-and-middle-sized high-pressure nitrogen and hydrogen gas compressor gas boosting had really that its air loss is little, output is high, the advantage of saving power.But because the to-and-fro motion of piston and piston rod, it can not be as pressure unit; Owing to need motor and driving mechanism thereof to drive piston rod and piston reciprocates to reach the purpose to gas boosting, it also is not suitable for as power plant in addition.
It is big and volume is little, the simple pressure cylinder of manufacturing process to the purpose of this invention is to provide a kind of delivery pressure or power, and it both can be used as pressure unit and has used, and also can be used as power plant and uses.
The object of the present invention is achieved like this.Existing single stage of pressure cylinder is improved, with (n-1) (n=2,3,4 ...) individual spacer ring (7) is separated into n little cylinder sleeve with cylinder sleeve (3) n etc., several pistons (6) correspondingly are set on mandrel (1) also place respectively in several little cylinder sleeves, so also just constituted a multistage (progression n=2,3,4 ...) pressure cylinder.It comprises cylinder sleeve (3), place the left end cap (2) and right end cap (14) of cylinder sleeve (3) left and right sides port, be on cylinder sleeve (3) axis and pass the mandrel (1) of left end cap (2) and axle sleeve (5) axially is provided with (n-1) (n=2 equably along cylinder sleeve (3) in cylinder sleeve (3), 3,4 ...) individual spacer ring (7) and branches such as cylinder sleeve (3) n are formed n little cylinder sleeve, in n little cylinder sleeve near on the mandrel (1) of spacer ring (7), or be respectively arranged with piston (6) at the right-hand member of mandrel (1), promptly on mandrel (1), be provided with n piston altogether, right end cap (14) is provided with forward import (10), left end cap (2) is provided with reverse import (13), then is respectively arranged with forward import (10) and oppositely import (13) in the both sides of spacer ring (7).This multistage (progression n=2,3,4 ...) pressure cylinder can be used as pressure unit and also can be used as power plant, is that the inner diameter d of cylinder sleeve (3) is the external diameter of mandrel (1) if set D, then the power of its output will be the single stage of pressure cylinder { 1+ (n-1) (D/2)
2-(d/2)
2)/(D/2)
2Doubly.
The present invention is owing to use (n-1) (n=2,3,4 ...) individual spacer ring is separated into n little cylinder sleeve with cylinder sleeve n etc., and n piston correspondingly is set on mandrel places respectively in n the little cylinder sleeve, and with multistage (the progression n=2,3,4 of single stage of pressure cylinder improvement becoming ...) pressure cylinder, causing the delivery pressure of mandrel or power is that { 1+ (n-1) is ((D/2) for the single stage of pressure cylinder
2-(d/2)
2)/(D/2)
2Doubly, and its volume is individual, and manufacturing process is simple, and as seen this is a kind of pressure cylinder of novel concept.
Fig. 1 is the structural representation of the embodiment of the invention.
Introduce embodiments of the invention below in conjunction with accompanying drawing.
Multistage as shown in Figure 1 (progression n=3) pressure cylinder, it comprises cylinder sleeve (3), place cylinder sleeve (a 3) left side, left end cap of right output port (2) and right end cap (14), place two spacer rings (7) in the cylinder sleeve (3), be on cylinder sleeve (3) axis and pass the mandrel (1) and the axle sleeve (5) of left end cap (2) and two spacer rings (7), and three pistons (6) constitute, two spacer rings (7) are divided into three little cylinder sleeves with cylinder sleeve (3) trisection, three pistons (6) are in respectively in three little cylinder sleeves near on the mandrel (1) of spacer ring (7), or be in the right-hand member of mandrel (1), right end cap (14) is provided with forward import (10), left end cap (2) is provided with reverse import (13), is respectively arranged with forward import (10) and oppositely import (13) in each spacer ring (7) both sides.Other, as among the figure 4 for seal ring, 9 and 8 be respectively to be in connecting bolt that the attaching nut of mandrel (1) right-hand member piston (5) and mandrel (1) and bullet pad, 14 and 12,11 are respectively cylinder sleeve (3) and right end cap (2), left end cap (13) and nut, bullet pad.This multistage (progression n=3) pressure cylinder is equipped with preparation, transmission and the control system of upward pressure gas or pressured fluid, it can make pressure unit or power plant use, if setting D and be internal diameter, the d of cylinder sleeve (3) is the external diameter of mandrel (1), then the delivery pressure of its mandrel will be the single stage of pressure cylinder { 1+ (n-1) ((D/2)
2-(d/2)
2)/(D/2)
2(n=3) doubly.It is during as pressure unit, pressed gas or pressured fluid are from just same import (10) input cylinder sleeve (3), and promoting three pistons (6) simultaneously to positive movement, three pistons (6) drive mandrel (1) and delivery pressure simultaneously, and are kept by the control system of pressed gas or pressured fluid; When needs shed pressure, then can will enter the pressed gas of cylinder sleeve (3) or pressured fluid commutation power from reverse import (13) input cylinder sleeve (3) from forward import (10) by above-mentioned control system.It is during as power plant, can be by the control system of pressed gas or pressured fluid, alternately with pressed gas or pressured fluid from forward import (10) and reverse import (13) input cylinder sleeve (3), and promote three pistons (6) simultaneously and do reciprocatory motion, three pistons (6) drive simultaneously again that mandrel (1) is done reciprocatory motion and defeated power.
Aforesaid multi-stage pressure cylinder, we it can be designed to progression be n=2,3,4 ... multi-stage pressure cylinder, it suitable especially as pressure unit or in inflammable and explosive place as power plant.
Aforesaid multistage (progression n=2,3,4 ...) pressure cylinder, we can also be designed to it the two ends output multi-stage pressure cylinder of equal delivery pressure in mandrel (1) two ends or power.
