Background technique
Along with the development of modern mechanical, pump uses more and more extensive at the machinery industry that continues, and one-way valve outbalance in the use of pump, one-way valve is widely used in factory, heating system, pressurized air, in the devices such as water supply, stop backflow or discharge, one-way valve can level or at right angle setting, effectively can reduce crushing, one-way valve is Chinese a lot of air-conditioning factory, Sunpower Corp. and building water supply and drainage company specify the product used, the one-way valve of current pump uses installation to there is many deficiencys, as obvious not in the effect of existing one-way valve tool regulating flow quantity, sometimes in adjustment process, there will be out-of-control phenomenon again, one-way valve is reacted sensitive not to the change of less pressure, thus delivery pressure can not be regulated in time, outlet pressure is unstable, the definite value precision of voltage regulation is lower, therefore, for the problems referred to above, a kind of multi-purpose type gas control one-way valve is proposed.
Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide a kind of multi-purpose type gas control one-way valve, there is regulating flow quantity effect, because valuator utilizes the feedback effect of delivery pressure and the amplification control bound of nozzle flapper, can react to the change of less pressure, thus delivery pressure is regulated in time, keep outlet pressure basicly stable, the advantage that the definite value precision of voltage regulation is higher.
For achieving the above object, the utility model is by the following technical solutions: a kind of multi-purpose type gas control one-way valve, comprises upper valve body, hexagon socket head cap screw, O type circle, piston spring, lower valve body, spool, nut, adjustable lever, adjustment seat, guide rod, nut setting sleeve and piston; Piston is installed in described upper valve body inside, and piston one end arranges hexagon socket head cap screw; Described hexagon socket head cap screw one end is fixed on guide rod and the guide rod the other end is positioned at valve core inside; Described guide rod side arranges the nut setting sleeve being positioned at lower valve body side, and lower valve inner arranges O type circle; Described lower valve body surface arranges piston spring, and piston spring and piston compact siro spinning technology; Described internal piston arranges O type circle, and O type circle is positioned at upper valve body internal surface; Described spool one end arranges adjustable lever, and adjustable lever surface mounting nuts; Between described lower valve body and adjustable lever, adjustment seat is set.
Further, described hexagon socket head cap screw is hexgonal structure, and hexagon socket head cap screw one end arranges upper valve body.
Further, described spool is T-shaped structure, and spool passes through O type circle compact siro spinning technology between two lower valve bodies.
Further, described nut is arranged at adjustment seat side, and two nut symmetries are positioned at adjustable lever both sides.
Further, described upper valve body is L shape structure, and upper valve body is symmetrical about guide rod.
The beneficial effects of the utility model are: one-way valve and other valves can form hydraulic control combination valve, for common Pilot operated check valve, when controlling mouth without pilot pressure, its effect is the same with common one-way valve, compact structure, working life is of a specified duration, and the effect of common one-way valve makes fluid along a direction flowing, can only not allow reverse refluence; Be arranged on delivery side of pump, system pressure impact can be prevented the impact of pump, during air pump inoperative, can prevent system fluid from flowing back to fuel tank through pump, one-way valve also can be used to separate oil circuit, prevents interference.
