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 the sealing ring in liquid valve seat, needle-valve and spring, sealing ring is loaded between liquid valve seat and needle-valve, and spring is housed above needle-valve, has liquid outlet above liquid valve seat.Its advantage in liquid without gas, goes out that liquid is smooth, and using effect is good.
Description
Technical field
Elastic fluid pump is the utility model is related to, is related to the setting of valve, espespecially a kind of piston pump exhaust structure.
Background technology
Flow container, flow container connection feed liquor check valve are installed, feed liquor check valve connects inlet to hydraulic cylinder, liquid in soap-solution device
Cylinder pressure connection outlet, outlet connect out liquid check valve, go out liquid check valve and 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 gas is carried in liquid, influence its use
Effect, go out liquid and have some setbacks.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of piston pump exhaust structure.
Technical scheme is used by the utility model solves its technical problem：A kind of piston pump exhaust structure, institute are provided
Stating piston 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
Have 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 close in liquid valve seat
Seal, needle-valve and spring, sealing ring are loaded between liquid valve seat and needle-valve, and spring is housed above needle-valve, had above liquid valve seat
Liquid outlet.
The piston pump is installed on soap-solution device, and feed liquor check valve connects 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, is gone out
Liquid check valve is closed under spring force.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, caused normal pressure is not enough to push out liquid check valve open.
3. when piston continues up, touched needle-valve, if now needle-valve be still not switched on piston will be by force
Push needle-valve open, hydraulic pressure gas in the jar or partially liq will discharge.Hydraulic cylinder will reduce many gases.For next time it is smooth go out liquid
Prepare.
If without this structure, go out liquid check valve and be possible to not open always, so as to whole pumping system do not go out liquid or
Go out liquid to have some setbacks, make thrashing.
The beneficial effects of the utility model are：Go out in liquid without gas, go out that liquid is smooth, and using effect is good.
Brief description of the drawings
The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is use state scheme of installation of the present utility model.
Fig. 2 is structural representation of the present utility model.
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 be piston, 32 be sealing ring, 33 be liquid valve seat, 34 be needle-valve, 35 be spring, 36 be into
Liquid check 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 utility model, the piston pump includes hydraulic cylinder 39, the and of piston 31
Feed liquor check valve 36, feed liquor check valve 36 are connected with hydraulic cylinder 39, it is characterised in that：Also include one to connect with hydraulic cylinder 39
Go out liquid check valve 30, it is described go out liquid check valve 30 include liquid valve seat 33 and loaded on sealing ring 32, the pin in liquid valve seat 33
Valve 34 and spring 35, sealing ring 32 are 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
There is liquid outlet 33 tops（It is not drawn into figure）.
Referring to Fig. 1, in embodiment of the present utility model, the piston pump 3 is installed on soap-solution device, feed liquor check valve 36
Connected with flow container 1.
The course of work is as follows：
1st, when piston 31 moves downward, negative pressure is produced in hydraulic cylinder 39.Feed liquor check valve 36 is under negative pressure effect
Open, go out liquid check valve 30 and closed 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 moves upwards, normal pressure, work of the feed liquor check valve 30 in normal pressure can be produced in hydraulic cylinder 39
With lower closing.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, caused normal pressure is not enough to push out liquid check valve 30 open.
3. when piston 31 continues up, needle-valve 34 has been touched, has still been not switched on if now going out liquid needle-valve 34, it is living
Plug 31 will push needle-valve 34 open by force, and gas or partially liq will discharge in hydraulic cylinder 39.It will be reduced perhaps in hydraulic cylinder 39
More gases.For next time it is smooth go out liquid prepare.
