Abstract
A kind of piston pump exhaust structure, the piston pump includes hydraulic cylinder, piston and feed liquor check valve, feed liquor check valve is connected with hydraulic cylinder, also include one connected with hydraulic cylinder go out liquid check valve, it is described go out liquid check valve include liquid valve seat and loaded on liquid valve seat in sealing ring, needle-valve and spring, sealing ring has liquid outlet loaded on spring, liquid valve seat top between liquid valve seat and needle-valve, is equipped with above needle-valve.Its advantage without gas in liquid, goes out that liquid is smooth, and using effect is good.
Description
Technical field
The present invention relates to elastic fluid pump, it is related to the setting of valve, espespecially a kind of piston pump exhaust structure.
Background technology
Flow container is installed, flow container connection feed liquor check valve, feed liquor check valve connects inlet to hydraulic cylinder, liquid in soap-solution device
Cylinder pressure connection outlet, outlet connects out liquid check valve, goes out liquid check valve and is driven by hydraulic cylinder piston, the soap lye in hydraulic cylinder is led to
Cross out the liquid outlet discharge of liquid check valve.Prior art it is this go out liquid structure can use in liquid carry gas, influence it to use
Effect, goes out liquid and has some setbacks.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of piston pump exhaust structure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of piston pump exhaust structure, the work are provided
Filling in pump includes hydraulic cylinder, piston and feed liquor check valve, and feed liquor check valve is connected with hydraulic cylinder, it is characterised in that：Also include one
It is individual connected with hydraulic cylinder go out liquid check valve, it is described go out liquid check valve include liquid valve seat and loaded on the sealing in liquid valve seat
Circle, needle-valve and spring, sealing ring have loaded on spring, liquid valve seat top between liquid valve seat and needle-valve, is equipped with above needle-valve
Liquid mouthful.
The piston pump is installed on soap-solution device, and feed liquor check valve is connected with flow container.
Action principle：
1. negative pressure when the piston is moving down, is produced in hydraulic cylinder.Feed liquor check valve is opened under negative pressure effect, goes out liquid list
Closed under spring force to valve.Part soap lye is drawn into hydraulic cylinder by feed liquor check valve.
2. when the piston is moving up, can produce normal pressure in hydraulic cylinder, feed liquor check valve is in the presence of normal pressure
Close.And go out liquid check valve under spring force, it is necessary to certain opening pressure.Now, if hydraulic cylinder in if any
Portion gas, due to the compressibility of gas, the normal pressure of generation is not enough to push out liquid check valve open
3. when piston is continued up, touched needle-valve, if now needle-valve is still not switched on piston and will pushed open by force
Needle-valve, hydraulic pressure gas in the jar or partially liq will be discharged.Hydraulic cylinder will reduce many gases.For next time it is smooth go out liquid do standard
It is standby.
If without this structure, going out liquid check valve and being possible to not open always, thus whole pumping system do not go out liquid or
Go out liquid to have some setbacks, make thrashing.
The beneficial effects of the invention are as follows：Go out without gas in liquid, go out that liquid is smooth, using effect is good.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the use state scheme of installation of the present invention.
Fig. 2 is the structural representation of the present invention.
In figure：1 it is flow container, 2 be top cover, 3 be piston pump, 4 be bodice, 5 is base；
In piston pump 3：31 it is piston, 32 be sealing ring, 33 be liquid valve seat, 34 be needle-valve, 35 be spring, 36 is feed liquor list
To valve, 37 be back-up ring, 38 be sealing ring, 39 be hydraulic cylinder, 30 be liquid check valve.
Embodiment
Referring to accompanying drawing, a kind of piston pump exhaust structure of the invention, the piston pump includes hydraulic cylinder 39, piston 31 and feed liquor
Check valve 36, feed liquor check valve 36 is connected with hydraulic cylinder 39, it is characterised in that：Also include one and going out that hydraulic cylinder 39 is connected
Liquid check valve 30, it is described go out liquid check valve 30 include liquid valve seat 33 and loaded on liquid valve seat 33 in sealing ring 32, needle-valve 34
With spring 35, sealing ring 32 is loaded between liquid valve seat 33 and needle-valve 34, and the top of needle-valve 34 is equipped with spring 35, liquid valve seat 33
There is liquid outlet side（It is not drawn into figure）.
Referring to Fig. 1, in an embodiment of the present invention, the piston pump 3 is installed on soap-solution device, feed liquor check valve 36 and liquid
Tank 1 is connected.
The course of work is as follows：
1st, when piston 31 is moved downward, negative pressure is produced in hydraulic cylinder 39.Feed liquor check valve 36 is opened under negative pressure effect,
Go out liquid check valve 30 to close under the effect of spring 35.Part soap lye is drawn into hydraulic cylinder 39 by feed liquor check valve 36.
2nd, when piston 31 is moved upwards, normal pressure, work of the feed liquor check valve 30 in normal pressure can be produced in hydraulic cylinder 39
Closed with lower.And go out liquid check valve 30 in the presence of spring 35, it is necessary to certain opening pressure.Now, if hydraulic cylinder 39
Inside there is portion gas, due to the compressibility of gas, the normal pressure of generation is not enough to push out liquid check valve 30 open.
3. when piston 31 is continued up, having touched needle-valve 34, still it is not switched on if now going out liquid needle-valve 34, piston 31
Gas or partially liq in needle-valve 34, hydraulic cylinder 39 will be pushed open by force to discharge.Many gas will be reduced in hydraulic cylinder 39
Body.For next time it is smooth go out liquid prepare.
