Description
Technical field
The present invention is relevant with pump, refers to especially a kind of piston type compression pump.
Background technique
The piston type compression pump of commonly using is that a piston is set in a body, this body has and is respectively used to receive and an entrance and an outlet of discharge liquid, form one first room between the entrance of this piston and this body, form one second room between the outlet of this piston and this body, and this piston has a through hole that this first, second room is communicated with.During towards the direction slippage of this outlet, the liquid in this second room is discharged from this outlet with high pressure when this piston; During towards the direction slippage of this entrance, the liquid in this first room can be supplemented to via the through hole of this piston this second room when this piston.Thus, this piston type compression pump can receive the water that general water supply equipment (for example water tap) provides, then with high pressure, water is discharged, and uses for sprinkler or spraying apparatus.
Yet aforementioned piston type compression pump is when discharging liquid, and the liquid in this second room has part to be back to this first room from the through hole of this piston, makes the fluid pressure that this pump provides be not so good as expection.And, the pressure that this piston produces towards the direction slippage of this entrance can hinder liquid and enter this first room from this entrance, water in this first room is gone out from this entrance adverse current, make the water shortage that flows into this second room, and then reduce the pressure that next stroke of this piston is discharged liquid.
In other words, the piston type compression pump of commonly using can't stably provide highly pressurised liquid, thereby still remains to be improved.
Summary of the invention
For the problems referred to above, main purpose of the present invention is to provide a kind of piston type compression pump, and it can stably provide highly pressurised liquid.
for achieving the above object, a kind of piston type compression pump provided by the present invention, it is characterized in that including: a pressurized cylinder has one first relative side and one second side, one and be used for allowing liquid enter entrance in described pressurized cylinder, and one is used for the outlet that allows liquid discharge from described pressurized cylinder, one slide device, for being located at slippingly described pressurized cylinder, described slide device includes a piston and one first check valve, described piston can be toward polyslip between the first side of described pressurized cylinder and the second side, form one first room between described piston and described pressurized cylinder the first side, form one second room between described piston and described pressurized cylinder the second side, described entrance and described outlet are communicated with described the first room and described the second room respectively, and described piston has a passage that is communicated with described the first room and described the second room, described the first check valve is located at described passage, to stop the liquid in described the second room to enter described the first room via described passage.
In the technological scheme of the invention described above, the entrance of described pressurized cylinder is towards a direction vertical with the slip direction of described slide device.
Also include one second check valve, described the second check valve is located at the entrance of described pressurized cylinder, flows out from described entrance to stop the liquid in described the first room.
Also include one the 3rd check valve, described the 3rd check valve is located at the outlet of described pressurized cylinder, flows into described the second room to stop liquid from described outlet.

Embodiment
Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be elaborated.
As shown in Figures 1 to 4, the piston type compression pump 10 that a preferred embodiment of the present invention provides consists predominantly of a pressurized cylinder 20, and a slide device 30.
Pressurized cylinder 20 includes the bonnet 23, that protecgulum 22, that a body 21, is fixedly arranged on body 21 front ends is fixedly arranged on body 21 rear ends and is arranged in regularly the side cover 24 of body 21 sidewalls, and an entrance 25 and an outlet 26 of being located at respectively side cover 24 and protecgulum 22.
Piston 32 is located in pressurized cylinder 20, form one first room 40 between piston 32 and pressurized cylinder the 20 one the first sides 27, form one second room 50 between piston 32 and pressurized cylinder the 20 one the second sides 28, the entrance 25 of pressurized cylinder 20 and export 26 and be communicated with the first room 40 and the second room 50 respectively, and piston 32 has a passage 322 that is communicated with the second room 50.
Piston rod 34 has a body 342 that extends towards the direction of pressurized cylinder 20 first sides 27 from piston 32 rear ends, and one is fixed in body 342 and is positioned at the outer link 344 of pressurized cylinder 20.In the present embodiment, the body 342 of piston rod 34 is connected with piston 32 one, but not as limit, but and the body 342 of piston rod 34 and also one connection of link 344.The body 342 of piston rod 34 is provided with a T-shaped through hole 346, and through hole 346 is communicated with the passage 322 of the first room 40 and piston 32, makes passage 322 be communicated with the first room 40.
Thus, liquid can enter the second room 50 via through hole 346 and passage 322 after entering the first room 40 from entrance 25, then is discharged by outlet 26.The first check valve 36 is located at passage 322, is used for stoping the liquid in the second room 50 to be back to the first room 40 via passage 322.The entrance 25 of pressurized cylinder 20 can be provided with one second check valve 60 again, is used for stoping the liquid in the first room 40 to flow out from entrance 25.The outlet 26 of pressurized cylinder 20 also can be provided with one the 3rd check valve 70, is used for stoping liquid to flow into the second room 50 from exporting 26.
As Fig. 5 and shown in Figure 6, the link 344 of piston rod 34 is used for being connected with a driver 80, make slide device 30 driven and traveling priority by driver 80, so make piston 32 and Sealing 38 along body 21 inwalls in past polyslip (as shown in Figures 3 and 4) between the second side 28 of pressurized cylinder 20 and the first side 27.In the present embodiment, driver 80 is an eccentric motor, and link 344 is provided with a slotted hole 348, and vertical D1 of slotted hole 348 is perpendicular to the slip direction D2 of slide device 30, and the live axle 82 of driver 80 is arranged in slotted hole 348.Thus, the rotation function that driver 80 provides can make slide device 30 traveling priorities, yet the form of driver 80 and link 344 is not as limit.
During towards the direction slippage of the second side 28, the liquid in the second room 50 only can be discharged from exporting 26 with high pressure, and can not be back to the first room 40 when piston 32; And the design that Sealing 38 has groove 382 can increase the interior liquid of the second room 50 and the area of contact of slide device 30, and then improves the hydraulic pressure that piston type compression pump 10 provides.
During towards the direction slippage of the first side 27, the liquid in the first room 40 only can be supplemented to the second room 50, and can not go out from entrance 25 adverse currents when piston 32, and the liquid in the second room 50 also can not spill from exporting 26; And entrance 25 is towards a direction D3 vertical with slip direction D2, and the pressure that can avoid piston 32 to produce hinders liquid and enters the first room 40 from entrance 25.Therefore, the second room 50 can be filled fast, makes the fluid pressure of piston 32 next stroke discharging can not reduce.Thus, piston type compression pump 10 can be stably at every one stroke all with equal high-pressure discharge liquid.
At last, must again illustrate, the constituent components that the present invention discloses in the aforementioned embodiment only for illustrating, can not be used for limiting the scope of patent protection of this case, and substituting or changing of other equivalent elements also should be contained by the scope of patent protection of this case.
