Abstract
The utility model discloses a pilot-operated cartridge two-way double-break valve which comprises a valve body, a valve element, a cam, a compression spring, a rotary shaft and a rotary handle. Two pairs of four-way liquid inlet and outlet holes are formed in the valve body, the valve element is inserted into the valve body and is in clearance fit with the valve body, two through holes are formed in the valve element and correspond to two inlet and outlet holes in the valve body, sealing sleeves are arranged on the peripheries of the through holes, the cam is arranged at the left end of the valve element and is in contact with the valve element, and the valve element can move rightwards under the rotation action of the cam, so that the through holes in the valve element can be communicated with inlet and outlet pipelines on the valve body, and the inlet and outlet holes of the valve can be simultaneously opened; the valve element can return to the original position by the aid of the compression spring, so that an inlet and an outlet of the valve can be simultaneously closed; the rotary shaft is mounted at the left edge of the valve body and can rotate at an optional angle, the cam is mounted on the rotary shaft and can be driven by the rotary shaft to rotate, and the rotary handle is mounted at the upper end of the rotary shaft and can drive the rotary shaft to rotate. The pilot-operated cartridge two-way double-break valve has the advantages of reasonable structure, convenience in operation, high sensitivity during operation, low cost and the like.
Description
Technical field
The utility model relates to a kind of liquid valve, is specifically applied to feeding pipe and discharge nozzle simultaneously open-minded, the hydraulic control plug-in mounting double on and off valve of simultaneously closing.
Background technique
The valve major part using is at present only applicable to a kind of turnover of medium, and the method that be applied to two or more medium turnover has: the one, adopt valve group, and the 2nd, adopt multiple-way valve.Valve group is mainly divided into two valve groups, three valve groups and five valve groups.They are to combine formation with several single valves, and structure is simpler, but too heavy, operation is trouble.Multiple-way valve is by a valve body, has multiple import and export on valve body, and its advantage is can multi-purpose valve, and a valve can replace multiple valves, connects multiple pipelines, and simple in structure, reliable.
Chinese patent CN2313116Y has announced a kind of two-position four-way valve, and it comprises the sealing gasket being arranged in order by cylindric valve seat, valve seat, stator, transposition sheet, rubber pad, retainer ring composition.This valve can be realized the turnover of two kinds of different mediums, but the defect such as this valve has complicated structure, and sensitivity is poor.Chinese patent CN1220360A once disclosed a kind of two position four-way valves, it is characterized in that, on the end of valve seat cylindraceous, circumferentially uniform four logistics that vary in size are imported and exported, and the cylinder end is upwards aligned in sequence with sealing gasket, stator, transposition sheet, increases slide plate, rubber pad, retainer ring.But the defects such as the designed valve of this patent has complicated structure, and sensitivity is poor.
Two position four-way valves that use on market now, ubiquity complex process, the defect such as cost is high, poor sealing.Be necessary this to improve.
Model utility content
The utility model provides and is applied to feeding pipe and discharge nozzle is simultaneously open-minded, the hydraulic control plug-in mounting double on and off valve of simultaneously closing.For achieving the above object, the utility model provides following technological scheme.
A kind of hydraulic control plug-in mounting double on and off valve, comprises valve body, spool, Compress Spring, cam, running shaft, swing handle and stuffing box gland; On described valve body, have two pairs of four-way turnover liquid material holes, described spool is inserted in described valve body, one end cover that described spool is stayed described valve body outside has described Compress Spring, described spool left end have one described in cam contact with it, described cam is arranged on described running shaft, described running shaft is inserted on described valve body, and a described swing handle is installed in described running shaft upper end.
Hydraulic control plug-in mounting double on and off valve described in the utility model, described spool is provided with two through holes, and through hole is equipped with stuffing box gland around.
Hydraulic control plug-in mounting double on and off valve described in the utility model, described feed inlet and outlet place scyewed joint.
