Build the product that discharge waters corporation specifies use, the check valve of current pump has many weak points, such as existing list using installation
Not obvious to valve tool regulating flow quantity effect, and sometimes during adjusting, out-of-control phenomenon occurs, check valve is to less
Pressure change is reacted not sensitive, so that output pressure can not be adjusted in time, outlet pressure is unstable, and definite value is steady
Pressure precision is relatively low, therefore, proposes a kind of multi-purpose type gas control one-way valve structures for the problems referred to above.
Content of the invention
Prior art can not meet the needs of people, not enough for making up prior art, the present invention is intended to provide a kind of multiplex
Type gas control one-way valve structures, have regulating flow quantity effect, because valuator utilizes feedback effect and the nozzle gear of output pressure
The amplification control bound of plate is so as to can react to less pressure change, so that output pressure is adjusted in time
Section, keeps the advantages of outlet pressure is basicly stable, and the definite value precision of voltage regulation is higher, solves the problems, such as in background technology.
For achieving the above object, the present invention employs the following technical solutions：A kind of multi-purpose type gas control one-way valve structures, including on
Valve body, hexagon socket head cap screw, O-ring, piston spring, lower valve body, valve element, nut, adjusting rod, adjustment seat, guide rod, nut positioning sleeve
And piston；Inside described upper valve body, piston is installed, and piston one end setting hexagon socket head cap screw；Described hexagon socket head cap screw one end is solid
Due to guide rod and the guide rod other end be located at valve core inside；The setting of described guide rod side is located at the nut positioning of lower valve body side
Setting O-ring inside set, and lower valve body；Described lower valve body surface arranges piston spring, and piston spring is tight with piston
Connect；Described internal piston arranges O-ring, and O-ring is located at upper valve body inner surface；The setting of described valve element one end is adjusted
Bar, and nut is installed on adjusting rod surface；Adjustment seat is set between described lower valve body and adjusting rod.
Further, described hexagon socket head cap screw is hexgonal structure, and hexagon socket head cap screw one end setting upper valve body.
Further, described valve element is T-shaped structure, and valve element is located at and is closely connected by O-ring between two lower valve bodies
Connect.
Further, described nut is arranged at adjustment seat side, and two nuts are symmetrically positioned in adjusting rod both sides.
Further, described upper valve body is L-shaped structure, and upper valve body is symmetrical with regard to guide rod.
The invention has the beneficial effects as follows：Check valve and other valves can form hydraulic control combination valve, for common hydraulic control one-way valve,
When control mouth no control pressure, it acts on as common check valve, compact conformation, and service life is long, common check valve
Effect is so that fluid can only be flowed along a direction, does not allow reversely to flow backwards；It is arranged on the outlet of pump, system pressure can be prevented
The impact to pump for the impact, during air pump inoperative, can prevent system fluid from flowing backwards oil sump tank through pump, check valve may further be used to separate oil
Road, prevents from disturbing.
