Abstract
The utility model relates to a two-position two-way control valve with a waney piston, which is provided with a valve body. A fluid inlet, a fluid outlet and a control port are arranged on the valve body, and one end of the valve body is provided with an end cover. The utility model is characterized in that the interior of a cylinder of the valve body is provided with the waney piston on which a sealing ring is sleeved; the waney piston is integrally made into three piston parts of a big diameter, a medium diameter and a small diameter; and the piston part of the small diameter faces the fluid inlet. The two-position two-way control valve has the advantages of high sensitivity, wide application range, self-compensation sealing effect and long service life.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of not 2/2-way control valve of isometrical piston that has.
Background technique
At present, the 2/2-way control valve is used widely in all trades and professions, has particularly become its critical piece in compressor.In compressor, the 2/2-way control valve generally is installed on the oil circuit filter pipeline afterwards, its effect mainly contains two: the one, behind compressor start, the 2/2-way control valve is in time opened, oil enters in the main frame by the oil circuit in the 2/2-way control valve, guarantees the lubricated and cooling of compressor; The 2nd, after compressor shutdown, the 2/2-way control valve is in time closed, and cuts off the passage to the main frame fuel feeding, in order to avoid compressor reverse rotation, lubricant oil is from the generation of accidents such as suction port overflows.And that the piston of this control valve is two ends is equal-sized cylindrical, this to control mouthful pressurization instrument requirement than higher, need the pressurization instrument to provide bigger air pressure or hydraulic pressure could promote piston and block fluid input, cause the sensitivity of control valve low, the use narrow limitation is big; Often adopt O-ring seals between piston and the valve body casing wall, the surface of contact of O-ring seals and valve body is very little, and sealing effect is poor, and seal ring in the piston sliding process easily wearing and tearing make escape of liquid, effect out of hand, thereby working life is not long.
Summary of the invention
The purpose of this utility model provides a kind of not 2/2-way control valve of isometrical piston that has, and has solved existing control valve and has used the problem that narrow limitation is big, sealing effect is poor, working life is short.
The technological scheme that the utility model adopted is: a kind of have a not 2/2-way control valve of isometrical piston, has valve body, be shaped on fluid input, fluid output and control mouth on it, valve body one end is provided with end cap, it is characterized in that being provided with not isometrical piston in the cylinder body of valve body, be with seal ring on the piston.
Described not isometrical piston is made into integration the piston section of big footpath, middle footpath and three kinds of different-diameters of path, and path piston section is towards fluid input.
The end face of described path piston section is equipped with the diaphragm seal that cooperates with the fluid input bore, the embedded spring of an end of big footpath piston section, and spring and end cap the inner contact.
Piston section edge, described big footpath is with y-shaped ring, and the intersection of little, middle footpath piston section is with y-shaped ring.
Be shaped on the adjusting screw that is used for regulated fluid flow size on the passage between described fluid input and the fluid output.
Described end cap edge is with O-ring seals, and end cap and valve body are limited by jump ring.
Described control mouth is circumscribed with two-position three way magnetic valve.
Described diaphragm seal is made duplex pulvilliform shape and is inlaid in the piston bottom surface, and the endoporus of its lower end surface and fluid input is along the opening-closing structure that constitutes valve.
Piston of the present utility model upper end area is greater than the lower end, when piston is in when upper, control mouthful in addition less air pressure or hydraulic pressure just can promote the piston downslide, thereby make this control valve highly sensitive, application area is wider; Adopt y-shaped ring between piston and the valve body, seal ring and piston and valve body area of contact increase, and have the self compensation sealing effect, long service life, and reliability and stability all are improved; Be shaped on the adjusting screw on the passage between the fluid entry and exit, the modulating valve of screwing on can be used to regulate the size of fluid flow on the passage.

Embodiment
As shown in Figure 1, having not, the 2/2-way control valve of isometrical piston comprises valve body 1 and not isometrical piston 4.Valve body 1 one ends are equipped with end cap 9, and the other end is shaped on fluid input A, and valve body 1 sidepiece radially is shaped on fluid output B and control mouthful C; End cap 9 peripheries are shaped on groove, are with the O-ring seals 8 that cooperates with it on the groove, and the upper end edge of end cap 9 contacts with the jump ring 10 that is stuck in valve body 1 one ends; Be shaped on the passage between fluid input A and the fluid output B and regulate screw 2, the modulating valve of screwing on can be used to regulate the size of fluid flow on the passage; A control mouthful C is circumscribed with two-position three way magnetic valve and controlled by it.The not isometrical piston 4 that is arranged in valve body 1 inside is made into integration the piston section of big footpath, footpath and three kinds of different-diameters of path; Path piston section is towards fluid input A, and its end face is equipped with the opening-closing structure that the diaphragm seal 3 that cooperates with fluid input A bore constitutes valve; The embedded spring 7 of one end of big footpath piston section, spring 7 contacts with end cap 9; The intersection of little, middle footpath piston section and piston section edge, big footpath all are shaped on groove, are with y-shaped ring 5 and y-shaped ring 6 on the groove respectively; Above-mentioned O-ring seals 8 all contacts with valve body 1 inner wall sealing with y- shaped ring 5,6.
Working procedure of the present utility model: gas or liquid are entered by fluid input A, when a control mouthful C does not have pressure oil to flow into, not isometrical piston 4 overcomes on spring 7 resistances under the effect of fluid input A pressure and moves, fluid input A and fluid output B are communicated, the flow size that in this process, can regulate fluid in the passage by the modulating valve of regulating on the screw 2; When control mouthful C had pressure oil to flow into and reach certain pressure, not isometrical piston 4 pressurizeds began to slide until blocking inlet toward fluid input A, thereby cut off A, B passage.
