Detailed description of the invention
For the ease of the understanding of those skilled in the art, being further described this utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
Refer to shown in Fig. 1 and Fig. 2, a kind of pipe compression buffer of the present utility model, including cylinder barrel 1, cylinder barrel 1 is provided with through hole 10, through hole 10 is along the through cylinder barrel of length direction 1 of cylinder barrel 1, the air inlet 11 and gas outlet 12 connected with through hole 10 it is additionally provided with on cylinder barrel 1, support spring 21 and piston 3 it is equiped with in the through hole 10 of described cylinder barrel 1, being respectively arranged at two ends with of cylinder barrel 1 supports spring 21, two one end supporting spring 21 close to each other are connected to piston 3, two pistons 3 are intervally installed, and air inlet 11, gas outlet 12 are between two pistons 3.
When specifically used, pipe compression buffer is connected to supply between gases at high pressure or the power source of other high-pressure fluid and plant equipment or pipeline, high-pressure fluid is connected to the air inlet 11 of pipe compression buffer and enters in cylinder barrel 1, entering the high-pressure fluid in cylinder barrel 1 promotes piston 3 towards two end motions of cylinder barrel 1, the impact kinetic energy of high-pressure fluid is converted into the elastic potential energy supporting spring 21, high-pressure fluid is delivered to plant equipment or pipeline by gas outlet 12 again through decompression, the dividing potential drop of pipe compression buffer, reduce the impulsive force suffered by plant equipment, the service life of prolonged mechanical equipment；Avoid high-pressure fluid to be fed directly to pipeline and cause pipeline generation booster phenomenon.
According to specific needs, can be one another in series those skilled in the art use by multiple pipe compression buffers；Multiple gas outlet 12 can also be offered, it is achieved one enters the function having more on the cylinder barrel 1 of pipe compression buffer；Multiple gas outlets 12 can also be flowed out via an opening first with hose connection again.As the case may be, those skilled in the art can select the support spring 21 of different coefficient of elasticity, for the buffering effect needed for the high-pressure fluid realization of different pressures.Pipe compression buffer carries out blood pressure lowering, dividing potential drop to high-pressure fluid, is gently discharged by fluid with the time of extending speed change the most again, thus realizes high-pressure fluid and plant equipment or pipeline cause the effect of less impulsive force.
In the present embodiment, being also equiped with back-moving spring 22 in the through hole 10 of described cylinder barrel 1, the two ends of back-moving spring 22 are connected on different pistons 3；After pipe compression buffer is stopped using, back-moving spring 22 can help piston 3 quickly to return to original position, in order to piston 3 can quickly reset, it is preferable that the coefficient of elasticity of back-moving spring 22 is more than the coefficient of elasticity supporting spring 21.
After high-pressure fluid enters in cylinder barrel 1, high-pressure fluid promotes piston 3 respectively towards two end motions of cylinder barrel 1, a part of impact kinetic energy of high-pressure fluid is converted into the elastic potential energy supporting spring 21, two pistons 3 are when being located remotely from each other, the length of back-moving spring 22 is elongated, and a part of impact kinetic energy of high-pressure fluid is converted into the elastic potential energy of back-moving spring 22.Back-moving spring 22 auxiliary support spring 21 reinforced pipe compression buffer carry out reducing pressure, dividing potential drop, it is achieved preferably buffering effect.
Refer to shown in Fig. 2, Fig. 3 and Fig. 4, the outer sheath of described piston 3 is provided with plastic tube 30, plastic tube 30 is between piston 3 and cylinder barrel 1, and plastic tube 30, for sealing the gap between piston 3 and cylinder barrel 1, effectively prevents high-pressure fluid from being spilt by the gap between piston 3 and cylinder barrel 1.According to specific needs, those skilled in the art can in the outside of piston 3 sheathed multiple plastic tubes 30.
In the present embodiment, blind hole 31, perforation 32 and blind slot 33 it is additionally provided with on described piston 3, blind hole 31 forms away from the one end supporting spring 21 is recessed from piston 3, perforation 32 and blind slot 33 form from the surface of piston 3 is recessed, perforation 32 connection blind slots 33 and blind holes 31, in plastic tube 30 is installed in blind slot 33 and hide in perforation 32；According to specific needs, multiple perforation 32 can be offered on piston 3.
In actual use, piston 3 slidably reciprocates and will result in the abrasion of plastic tube 30, plastic tube 30 after abrasion cannot play good sealing effectiveness, through offering blind hole 31 on piston 3, perforation 32 and blind slot 33, after high-pressure fluid enters in cylinder barrel 1, high-pressure fluid flow to blind slot 33 from blind hole 31 perforated 32, in being installed in blind slot 33 due to plastic tube 30 and cover perforation 32, high-pressure fluid extruding plastic tube 30 makes it move from piston 3 to the barrel of cylinder barrel 1, effect is held due to high-pressure fluid, gap between piston 3 and cylinder barrel 1 can be sealed by sealing ring after abrasion again.
Two described pistons 3 are equipped with protruded stigma 34 away from the one end supporting spring 21, in the present embodiment, protruded stigma 34 is positioned at blind hole 31, connecting hole 35 is offered on protruded stigma 34, the opposite end of back-moving spring 22 is respectively equipped with snap fit 23, in snap fit 23 is installed in connecting hole 35 and then is linked together with piston 3 by back-moving spring 22.
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the two ends of described cylinder barrel 1 are also equiped with block 13, the two ends supporting spring 21 are connected on block 13 and piston 3, during the assembling of pipe compression buffer, support spring 21 by one to load in through hole 10 from one end of cylinder barrel 1, a block 13 is installed in one end of cylinder barrel 1；The two ends of back-moving spring 22 are connected on two pistons 3, the piston 3 connected, back-moving spring 22 are loaded in through hole 10 from the other end of cylinder barrel 1；Again another is supported spring 21 to load in through hole 10 from the other end of cylinder barrel 1, finally another block 13 is installed in the other end of cylinder barrel 1.
In the present embodiment, the perforate 14 of through block 13 is offered on described block 13, perforate 14 is for by the through hole 10 between piston 3 and block 13 and pipe compression buffer ft connection, when the high-pressure fluid in cylinder barrel 1 by gap escape between piston 3 and cylinder barrel 1 to after between piston 3 and block 13, the outside of pipe compression buffer can be discharged to by perforate 14, prevent from causing the buffering effect of pipe compression buffer to reduce because accumulating more high-pressure fluid between piston 3 and block 13.
Understanding this utility model in sum is to have above-described good characteristic, is made it on using, promotes the usefulness not having in conventional art and have practicality, become the product of a great practical value.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the most all will change, this specification content should not be construed as restriction of the present utility model.
