Embodiment
With specific embodiment, the utility model is further described below, see Fig. 1-9:
A kind of air compressor opened and closed based on ball is shut down and starts discharge mechanism, be applicable to the air compressor system (see Fig. 1) be made up of parts such as compressor 1, gas tank 2, check valve 3 and outlet pipes 4, wherein the task of compressor 1 be air working medium is carried out compress to improve its pressure, the task of gas tank 2 is that to store be prevent the pressurized gas in gas tank 2 to be back in compressor 1 through the pressurized gas of overcompression, the effect of check valve 3, the task of outlet pipe 4 is delivered in gas tank 2 by the pressurized gas that compressor 1 is discharged, here, outlet pipe 4 refers to the pipeline be connected to by compressor 1 between check valve 3, check valve 3 is actually an one-way valve, and gas can only enter in gas tank 2 from outlet pipe 4 via check valve 3, and can not be back in outlet pipe 4 via check valve 3 in gas tank 2 conversely, it should be noted that, the check valve 3 in the utility model can be an annex of gas tank 2, and therefore check valve 3 also can be referred to as the check valve 3 of gas tank 2, described compressor 1 includes piston 1a, connecting rod 1b, cylinder 1c, valve plate seat 1d, outlet valve 1e, cylinder cap 1f, the critical pieces (see Fig. 1) such as exhaust cavity 5 and air-inlet cavity 8, connecting rod 1b moves by the driving of bent axle also and then driven plunger 1a makes back and forth movement in cylinder 1c, so by piston 1a, cylinder 1c, the active chamber that valve plate seat 1d surrounds is that periodic volume changes, when working chamber volume increases, gas pressure step-down forms certain degree of vacuum in it, now ambient atmosphere is inhaled in it via air-inlet cavity 8, the gas be closed when working chamber volume diminishes within it is compressed pressure increase, gas when pressure rises to predetermined value in active chamber is pushed outlet valve 1e open and enters within exhaust cavity 5, enter in gas tank 2 finally by by outlet pipe 4 and check valve 3.Characteristic of the present utility model is: or/and on the cylinder cap 1f of compressor discharge chamber 5 correspondence on the section of the outlet pipe 4 between the check valve 3 of compressor exhaust valve 1e to gas tank 2, the duct 7a being provided with relief hole 7 and being interconnected with this relief hole 7, shown relief hole 7 is communicated with ambient atmosphere, ball 6 is mounted with in described duct 7a, described ball 6 control relief hole 7 open with close disconnected: when ball 6 moves along duct 7a and props up relief hole 7, described relief hole 7 is closed disconnected, and when ball 6 departs from relief hole 7, described relief hole 7 is opened, when relief hole 7 is opened, outlet pipe 4 inside and exhaust cavity 5 inside are communicated to ambient atmosphere by this relief hole 7, when relief hole 7 is closed disconnected, outlet pipe 4 inside and exhaust cavity 5 inside cannot be communicated with ambient atmosphere via this relief hole 7, it is pointed out that the inside of outlet pipe 4 is communicated with the inside of compressor discharge chamber 5, obviously when the inside of outlet pipe 4 or the inside of exhaust cavity 5 is not when being emptied completely, now no matter whether ball 6 covered relief hole 7 completely, the one side that this ball 6 bears lower air pressure relief hole 7 dorsad towards the one side of relief hole 7 then bears higher air pressure, that is effect has certain difference force on the body of ball 6, this difference force always attempts pressed to by ball 6 and be pressed on the aperture of relief hole 7, thus tries hard to the passage of closed relief hole 7, it is to be noted, the gravity that ball 6 tool in the utility model is certain, and utilize this weight resistance to act on gas differential pressure power on ball 6 body, thus the passage of relief hole 7 is opened in attempt, the gravity of obvious ball 6 and the gas pressure difference acted on ball 6 body decide the through and off of relief hole 7, in other words ball 6 can control relief hole 7 open with close disconnected: when the gravity of ball 6 be greater than act on its double-edged gas differential pressure power and make ball 6 can not cover relief hole 7 completely time, relief hole 7 is in opening state, now outlet pipe 4 inside and exhaust cavity 5 inside are communicated to ambient atmosphere by this relief hole 6, corresponding is that compressor is in unloaded state with it, when act on the double-edged gas differential pressure power of ball 6 be greater than ball 6 itself gravity and ball 6 is pressed to and cover completely seal up relief hole 7 time, relief hole 7 is in closing disconnected state, now outlet pipe 4 inside and exhaust cavity 5 inside cannot be communicated with ambient atmosphere via this relief hole 7, and corresponding is the working state that compressor 1 is in normal output squeezing air with it.Working principle of the present utility model is: when compressor gas supplied pressure is up to standard and when shutting down, air pressure in outlet pipe 4 can decline gradually along with the leakage in the gap, small everywhere sealing engagement face between the outlet valve 1e of compressor 1 to check valve 3, when air pressure drops to setting threshold value, ball 6 is applied to its back pressure (i.e. gas differential pressure) with it and landing by overcoming under the effect of its gravity, now relief hole 7 be opened thus by outlet pipe 4 inner and exhaust cavity 5 inner with ambient atmosphere conducting, realize unloading thus, when compressor is reset, relief hole 7 is not closed completely due to the weight resistance effect of ball 6 within certain period, now relief hole 7 and ambient atmosphere or and air-inlet cavity 8 between still keep conducting pressure release state, so the air pressure in outlet pipe 4 and exhaust cavity 5 will maintain the state of low pressure, along with the increase of rotating speed, because the output gas flow of compressor is much larger than the leakage rate of relief hole 7, so the air pressure in outlet pipe 4 and in exhaust cavity 5 can rise gradually, the gas differential pressure be applied on ball 6 body also becomes large gradually, ball 6 will be forced to close relief hole 7 when gas differential pressure power is greater than gravity, in other words from unloaded state to relief hole 7 completely close have a bit of delayed time delay, the time-delay closing of ball 6 is the smooth starting of compressor 1 and moves to rated speed and create condition just, realize start thus and start unloading.Notice that spherical ball 6 structure is very simple, its space occupy-place is also very little, therefore the utility function that discharge mechanism of the present utility model possesses simply, reliable and occupy-place is little.
The utility model is in order to realize unloading quickly when compressor 1 is shut down, transverse holes 7b (see Fig. 1, Fig. 2 and Fig. 3) is provided with in the 7a of duct, when ball 6 depart from relief hole 7 fall after rise time, the pressurized gas of outlet pipe 4 inside and exhaust cavity 5 inside will be leaked to ambient atmosphere via duct 7a and relief hole 7 by transverse holes 7b in advance, thus realize unloading; It should be noted that, transverse holes 7b can be that horizontal arrangement (as depicted in figs. 1 and 2) may also be (as shown in Figure 3) that be in tilted layout; It is to be noted in addition, when compressor is reset, namely air-flow is had to pass through in transverse holes 7b, now according to Bernoulli's fluid flowing law, air pressure in the 7a of duct is inevitable lower than the air pressure in exhaust cavity 5, that is meaning that the air pressure being applied to ball 6 top also must be less, the gas differential pressure be in other words applied on ball 6 will increase, and now when gas differential pressure is greater than the gravity of ball 6, ball 6 is offered and moved up and final shutoff relief hole 7.In addition, longitudinal groove 7c (as shown in Figure 4), radial through slot 7d (as shown in Figure 5) are set in the 7a of duct and also can realize unloading when compressor 1 is shut down quickly; Certainly; the internal diameter of duct 7a is greater than the external diameter (see Fig. 6 and Fig. 7) of ball 6; or taper hole shape (Figure 8 shows that taper hole and bottom taper hole, Outside diameter is greater than the diameter of ball 6), can realize unloading equally quickly when compressor 1 is shut down.
Duct 7a of the present utility model and relief hole 7 can be arranged in an independent cock 9, and described cock 9 is fastened on (as shown in Figure 9) on the cylinder cap 1f of compressor 1.
Compared with prior art, outstanding advantages of the present utility model is: adopt the spherical ball 6 with certain gravity to control keying condition that relief hole 7 and low pressure ambient atmosphere carry out being communicated with and moment, the exhaust back pressure that compressor 1 faces lower numerical value within the initial period of starting is controlled with this, thus realize the starting unloading of compressor 1, for the smooth starting of compressor 1 creates an enabling environment.Because the ball 6 in the utility model is common spheroidal structure, not only structure is simply easy to install, and is the high parts of functional reliability, therefore possesses simple, reliable and that occupy-place is little utility function.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit protection domain of the present utility model according to this; therefore: all various equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
