Abstract

The invention belongs to the field of mechanical devices, and in particular relates to a liquid rotary valve used for a sheet processing machine. The liquid rotary valve used for the sheet processing machine comprises a valve body, and is characterized in that a cam is arranged below the valve body, a push rod, a valve pipe and a baffle are arranged in the valve body, the lower part of the push rod is in contact with the cam, the valve pipe is arranged above the push rod, the baffle is arranged above the valve pipe, the cam is rotated along a rotating shaft, and the rotating shaft is driven to operate by the drive device. According to the rotary valve with the cam adopting the abovementioned structures, when the cam is rotated, the valve pipe is controlled to open or close, and the valve pipe is controlled to a semi-opened state, so that the flow of the valve pipe is controlled.

Description

A kind of pelleter is used the liquid in rotation valve

Technical field

The invention belongs to the mechanical device field, be specifically related to a kind of pelleter and use the liquid in rotation valve.

Background technique

The cell pelleter can be used valve body and open or close the liquid road in the process of film-making, and at present mostly used valve body is solenoid valve, and the shortcoming of solenoid valve is, can only be with one group of valve body motion, can not control a plurality of valve bodies simultaneously, can not control many valve pipes; Solenoid valve can only open or close, and can not control semi-open state, like need to the valve management and control built in semi-open state, solenoid valve then can not meet the demands; Power consumption is many, ability adhesive under the "on" position, and electric current is big; Need a plurality of solenoid valves when controlling a plurality of valve pipe, institute takes up space big, and cost is high.In view of solenoid valve has above shortcoming, need the valve body that film-making is used be improved.

Summary of the invention

For solving the problems of the technologies described above; The invention provides a kind of pelleter and use the liquid in rotation valve; This rotary valve promotes the catch bar in the valve body through cam; Make the valve pipe be in unlatching, closed or semi-open state, flow that at any time can the control valve pipe has overcome the defective that solenoid valve can not the control valve pipe be in semi-open state.

Rotary valve of the present invention is realized through following technical proposals:

A kind of pelleter is used the liquid in rotation valve, comprises valve body and the valve pipe that is positioned at valve body, and there is cam the valve body below; Valve inner has catch bar, valve pipe and baffle plate; The bottom of catch bar contacts with cam, and the top of catch bar is the valve pipe, and there is baffle plate valve pipe top; Running shaft is arranged in the cam, and this running shaft is by its operation of drive device drives.

Preferably, at least one cam being arranged on the above-mentioned running shaft, can be that a plurality of cams are in series on running shaft.

Preferably, at least one valve body is arranged on the cam.

Preferably, two valve bodies are arranged on the cam, also can a plurality of valve bodies be set, during cam rotation, drive the operation of many group valve bodies, thereby control the flow of many valve pipes according to concrete use condition.

Beneficial effect of the present invention is, has adopted the rotary valve that has cam of said structure, cam in rotary course, unlatching or closure that not only can the control valve pipe, also can the control valve pipe in the flow of liquid; Among the present invention, be provided with multiple cams and valve body, this rotary valve can be controlled the running state of many valve pipes simultaneously thus.

Among the figure, 1-baffle plate, 2-valve pipe, 3-valve body, 4-catch bar, 5-cam, 6-running shaft.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done explanation further, so that those skilled in the art understand the present invention.

Embodiment 1

A kind of pelleter is used the liquid in rotation valve, comprises valve body 3, and there is cam 5 valve body 3 belows; There are catch bar 4, valve pipe 2 and baffle plate 1 in valve body 3 inside; The bottom of catch bar 4 contacts with cam 5, and the top of catch bar 4 is valve pipes 2, and there is baffle plate 1 valve pipe 2 tops; Running shaft 6 is arranged in the cam 5, and running shaft 6 is by its operation of drive device drives.

This rotary valve is when operation, and drive device drives cam 5 rotates, and the catch bar 4 of cam 5 tops is squeeze valve pipe 2 upwards, and the valve pipe 2 between baffle plate 1 and catch bar 4 is in unlatching, closed or semi-open state according to specific circumstances.

Embodiment 2

A kind of pelleter is used the liquid in rotation valve, comprises valve body 3, and there is cam 5 valve body 3 belows; There are catch bar 4, valve pipe 2 and baffle plate 1 in valve body 3 inside, and the bottom of catch bar 4 contacts with cam 5, and the top of catch bar 4 is valve pipes 2; There is baffle plate 1 valve pipe 2 tops, and above cam 5 has five groups, and these five groups of cams 5 are arranged along running shaft 6 parallel longitudinals and are connected on the running shaft 6; Running shaft 6 in actual moving process, can be selected the group number of cam by its operation of drive device drives as the case may be.

Embodiment 3

A kind of pelleter is used the liquid in rotation valve, comprises valve body 3, and there is cam 5 valve body 3 belows; There are catch bar 4, valve pipe 2 and baffle plate 1 in valve body 3 inside, and the bottom of catch bar 4 contacts with cam 5, and the top of catch bar 4 is valve pipes 2; There is baffle plate 1 valve pipe 2 tops, and running shaft 6 is arranged in the cam 5, and this running shaft 6 is by its operation of drive device drives; Two valve bodies 3 are arranged on the cam 5, and the position and the running shaft of these two valve bodies 3 are centrosymmetric.

Above valve body number can be selected according to concrete needs, also can be at the valve body that is provided with on the same cam more than three or three; Cam also can be the more group numbers except above-mentioned five groups, and such a conversion also drops within protection scope of the present invention.
