Abstract
The utility model discloses a cartridge type two-way double-break valve comprising a valve body, a valve spool, a compression spring, a cam, sealing rings and a rotating shaft. Two pairs of four-way liquid feed and discharge holes are formed in the valve body, the inside of the valve body is divided into an upper cavity and a lower cavity, two pairs of four-way liquid feed and discharge pipelines on the valve body are communicated with the two cavities respectively, the valve spool is inserted into the valve body, the large end of the valve spool separates the upper cavity and the lower cavity of the valve body, the sealing rings sleeve the valve spool, and the cam is in contact with the upper end of the valve spool. The cam rotates to enable the valve spool to move downwards, the upper and lower cavities of the valve body are allowed to be communicated, then the feed and discharge holes of the valve are opened simultaneously, the compression spring can enable the valve spool to return to the original position, and then the feed and discharge holes of the valve are closed at the same time. The rotating shaft is inserted into the upper side of the valve body and can rotate by any angle, the cam is mounted on the rotating shaft, and a rotating handle is mounted at the left end of the rotating shaft and can drive the rotating shaft to rotate. The cartridge type two-way double-break valve has the advantages of reasonable structure, convenience in operation, high in sensitivity during operation 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 plug-in type 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 92204929 has been announced a kind of four ways five-way stopcock, and it comprises valve body and spool, and valve body is provided with five passages, wherein four at grade and be crossing distribution, another with revolve core coaxial line, and with front four vertical.But the described technological scheme of this patent is difficult to flow out different medium by the switching of revolving core in same passway.Chinese patent CN 2679442Y has announced a kind of four-way change-over valve, it includes valve body, valve plate, valve rod and seal ring, valve body divides three layers along stem shaft to rearranging by four cavitys, two cavitys of layer are divided into two cavitys by longitudinal plate therein, between longitudinal three cavitys, respectively have a valve seat, each cavity one side all has valve port.The defects such as although this patent can solve the problem that valve quantity is many, and 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.
Model utility content
The utility model provides and is applied to feeding pipe and discharge nozzle is simultaneously open-minded, the plug-in type double on and off valve of simultaneously closing.For achieving the above object, the utility model provides following technological scheme.
A kind of plug-in type double on and off valve, comprises valve body, spool, Compress Spring, cam, seal ring, running shaft and swing handle; Also be included in and on described valve body, have two pairs of four-ways turnover liquid material holes, the large end of described spool is inserted in described valve body, the small end cover of described spool has a described Compress Spring, the upper end of described spool 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.
Described in plug-in type double on and off valve described in the utility model, in valve body, divide and have upper and lower two chambeies.
Feed inlet and outlet place scyewed joint described in plug-in type double on and off valve described in the utility model.
Cam and running shaft described in plug-in type double on and off valve described in the utility model, connect with flat key between swing handle and running shaft.
Turnover liquid material hole described in plug-in type double on and off valve described in the utility model on valve body can be asymmetric.
Adopt the beneficial effect of above technological scheme to be: valve body is box typed structure, compact structure; Spool adopts hole shaft clearance to coordinate with valve body, good seal performance; Spool is better by its sensitivity of break-make of piston type motion control valve.

Embodiment
Describe preferred implementation of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, plug-in type double on and off valve has two pairs of four-ways turnover liquid material holes on valve body 7, upper and lower two cavitys of the interior part of valve body 7, and two cavitys communicate, and on valve body 7, two pairs of four-way liquid in-out pipe materials communicate respectively at two cavitys; Spool 8 is inserted in valve body 7, spool 8 is Spielpassung with valve body 7, and the large end of spool 8 cuts off two chambeies up and down of valve body 7, and on spool 8, cover has seal ring 9, the small end cover of spool 8 has a Compress Spring 6, at running shaft 5 of upside plug-in mounting of valve body 7, running shaft 5 can Arbitrary Rotation, and a cam 3 is installed in the stage casing of running shaft 5, connect with flat key 4, cam 3 small ends contact with spool 8, and a swing handle 1 is equipped with in running shaft 5 upper ends, connect with flat key 2.
Introduce working principle of the present utility model below.
Referring to Fig. 1 and Fig. 3, swing handle 1 is in the effect backspin turnback of shelves iron, and running shaft 5 is with moving cam 3 Rotate 180 degree, cam 3 promotes spool 8 Compress Springs 6 and declines, spool 8 drops to the position of Fig. 2, the two chamber conductings up and down of valve body 7, and the material feeding mouth of valve and discharge port are opened simultaneously; Under the effect of shelves iron, swing handle 1 Rotate 180 degree, running shaft 5 is with moving cam 3 Rotate 180 degree, and spool 9 is got back to original position under the effect of spring 6, spool 8 inner upper and lower two chambeies of closed valve 7, the material feeding mouth of valve and discharge port are closed simultaneously.
