Mouthful, it is provided with spring between the rear end of the valve element and the liquid return hole；
Under naturalness, spring promotes the valve element to shift to the inlet, and the working hole is connected with the liquid return hole；
Under entering liquid status, valve element compression spring described in liquid-driving shifts to the liquid return hole, the working hole with it is described enter
Liquid mouth is connected.
The pressure charging system of the present invention, including supercharger, choke plug, time liquid water tank, the supercharger, choke plug and time liquid water
Above-mentioned alternating check valve is connected between case,
As seen from the above technical solution provided by the invention, alternately check valve and supercharging provided in an embodiment of the present invention
System, due to the alternately valve body of check valve inlet and liquid return hole are respectively arranged at two ends with, and working hole, valve are provided with the middle part of valve body
The front end of core is provided with spring towards inlet between the rear end of valve element and liquid return hole, and alternately check valve is accessed the big chamber of supercharger
And choke plug between, alternately the inlet of check valve connects choke plug, and alternately the liquid return hole of check valve takes back liquid pipeline, alternately unidirectional
The working hole of valve connects the big chamber of supercharger, and in being applied to the pressure charging system of laboratory, stable supercharging improves test efficiency again.

Specific embodiment
The embodiment of the present invention will be described in further detail below.
The alternating check valve of the present invention, preferably specific embodiment is as shown in Figure 1 and Figure 2 for it：
Including valve body, valve element, described valve body is respectively arranged at two ends with inlet and liquid return hole, sets in the middle part of the valve body
Have a working hole, the valve element in the valve body, the front end of the valve element towards the inlet, the rear end of the valve element with
Spring is provided between the liquid return hole；
Under naturalness, spring promotes the valve element to shift to the inlet, and the working hole is connected with the liquid return hole；
Under entering liquid status, valve element compression spring described in liquid-driving shifts to the liquid return hole, the working hole with it is described enter
Liquid mouth is connected.
The inlet and liquid return hole are respectively equipped with joint.
The pressure charging system of the present invention, its preferably specific embodiment is as shown in Figure 3：
Including supercharger, choke plug, liquid water tank is returned, connect between the supercharger, choke plug and time liquid water tank and have the right
The alternating check valve described in 1 or 2 is required,
The big chamber of the supercharger is connected with the working hole of the alternately check valve, the choke plug with it is described replace it is unidirectional
The inlet connection of valve, described time liquid water tank is connected with the liquid return hole of the alternately check valve.
The present invention is applied in the pressure charging system of laboratory, and medium is emulsion, alternately check valve is accessed supercharger big
Between chamber and choke plug.Alternately the inlet of check valve connects choke plug, and alternately the liquid return hole of check valve takes back liquid pipeline, alternately single
The big chamber of supercharger is connect to the working hole of valve.
Specific embodiment：
As shown in figure 3, only seeing topping up/be pressurized this group of solenoid directional control valve.
Operation principle is as follows：1. during topping up action, enter from two check valves of solenoid directional control valve emulsion Jing out and increase
After the loculus of depressor, promote piston rod to compress big chamber, make the big intracavity of supercharger emulsion flow through alternately the working hole of check valve,
Liquid return hole enters back liquid water tank, and inlet is obstructed.Because the emulsion of the big chamber outflow of supercharger is not through choke plug and electromagnetism
Commutation valve group, but return liquid system has been returned directly to, the topping up time is shortened, improve test efficiency.2. during pressurizing action, from
Solenoid directional control valve (master control valve group) emulsion out flows through choke plug, alternately the inlet of check valve, working hole enter supercharging
The big chamber of device, liquid return hole is obstructed, promotes piston rod compression loculus, makes supercharger loculus flow out high-pressure emulsion.Due to through section
The stifled throttling of stream, the emulsifying flow velocity for flowing out now is very slow, can reach the effect of stable supercharging.
Beneficial effects of the present invention：
Can apply to test it is indoor all need the pressure charging system of supercharger, it is not necessary to too big change, only need one
Alternately check valve and its joint, now very good through 20000 test effects, and range of application and prospect are boundless；
It is easy to maintenance using flexible.According to the difference of its boost pressure, the pore size of choke plug can be arbitrarily changed, be given
Larger development space has been reserved using unit.
Replace being used in combination for check valve and choke plug in the present invention, belong to the first in this area；The present invention is in supercharging system
Stable supercharging can be reached in system, test efficiency can be improved again, belong to pioneering in this area；The present invention is exclusively for laboratory supercharging
System design, meets the demand of its high workload pressure.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, the change or replacement that can be readily occurred in,
All should be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be defined.
