Embodiment
To be described in further detail the utility model embodiment below.
Alternately one-way valve of the present utility model, preferably embodiment is as shown in Figure 1 and Figure 2 for it:
Comprise valve body, spool, the two ends of described valve body are respectively equipped with liquid entering hole and liquid return hole, and the middle part of described valve body is provided with working hole, and described spool is located in described valve body, the front end of described spool, towards described liquid entering hole, is provided with spring between the rear end of described spool and described liquid return hole;
Under nature, spring promotes described spool and shifts to described liquid entering hole, and described working hole is communicated with described liquid return hole;
Under feed liquor state, described in liquid-driving, spool Compress Spring shifts to described liquid return hole, and described working hole is communicated with described liquid entering hole.
Described liquid entering hole and liquid return hole are respectively equipped with joint.
Pressurization system of the present utility model, preferably embodiment is as shown in Figure 3 for it:
Comprise pressurized machine, choke plug, return liquid water tank, described pressurized machine, choke plug and return the alternately one-way valve be connected with between liquid water tank described in claim 1 or 2,
The large chamber of described pressurized machine is connected with the working hole of described alternately one-way valve, and described choke plug is connected with the liquid entering hole of described alternately one-way valve, and described time liquid water tank is connected with the liquid return hole of described alternately one-way valve.
The utility model is applied in the pressurization system in laboratory, and medium is emulsified liquid, alternately between the one-way valve access large chamber of pressurized machine and choke plug.Alternately the liquid entering hole of one-way valve connects choke plug, and alternately the liquid return hole of one-way valve takes back liquid pipeline, and alternately the working hole of one-way valve connects the large chamber of pressurized machine.
Specific embodiment:
As shown in Figure 3, this group solenoid directional control valve of topping up/supercharging is only seen.
Working principle is as follows: 1. during topping up action, from solenoid directional control valve emulsified liquid out after two one-way valves enter the loculus of pressurized machine, promote piston rod and compress large chamber, make that the emulsified liquid in the large chamber of pressurized machine flows through the working hole of alternately one-way valve, liquid return hole enters back liquid water tank, liquid entering hole is obstructed.Because the emulsified liquid of pressurized machine large chamber outflow is not through choke plug and solenoid directional control valve group, but directly get back to return liquid system, shortened the topping up time, improve test efficiency.2. during pressurizing action, from the large chamber that solenoid directional control valve (main control valve group) emulsified liquid out flows through the liquid entering hole of choke plug, alternately one-way valve, working hole enters pressurized machine, liquid return hole is obstructed, promotes piston rod compression loculus, makes pressurized machine loculus flow out high-pressure emulsion.Due to the throttling through choke plug, the emulsified liquid flow velocity flowed out now is very slow, can reach the effect of stable supercharging.
The beneficial effects of the utility model:
Can be applied in laboratory that all need the pressurization system of pressurized machine, not need too large change, only need alternately one-way valve and a joint thereof, it is very good through 20000 test effects to show, application area and prospect boundless;
Use flexibly, easy to maintenance.According to the difference of its boost pressure, the pore size of choke plug can be revised arbitrarily, reserve larger development space to applying unit.
Replace the conbined usage of one-way valve and choke plug in the utility model, belong to the first in related domain; The utility model can reach stable supercharging in pressurization system, can improve test efficiency again, belongs to pioneering in related domain; The utility model is the design of laboratory pressurization system specially, meets the demand of its high workload pressure.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
