Abstract
The utility model discloses an electromagnetic integrating change valve for a medical operating table, which is an integrated combined control unit which is composed of two electromagnetic change valves and a hydraulic control one-way valve which are arranged on same valve seat body. Two actuating members can be controlled simultaneously; compared with the prior art, the utility model not only has the basic functions and technical characteristics of a common electromagnetic change valve but also has the advantages of small volume, light weight, sensitive direction change, long service life, convenient installation, etc.
Description
One, technical field
This utility model relates to a kind of medical operating platform, particularly relates to the control element on a kind of operating-table, goes into A61G13/00.
Two, background technology
At present having a kind of in the control element that adopts on the operating-table equipment is general irony solenoid directional control valve, this reversal valve exist volume big, install and use inconvenience, defective such as the sensitive reversing degree is low and service life is short.
Three, utility model content
The purpose of this utility model is will provide a kind of can overcome the common reversal valve that adopts on the existing operating-table equipment and have many insufficient novel control units---operating-table is with electromagnetism integrated change valve (hereinafter to be referred as reversal valve).This reversal valve can adopt following technical scheme to implement: it is contained in the integrated group control unit of forming on the same valve body by two identical in structure solenoid directional control valves and a hydraulic control one-way valve.Wherein solenoid directional control valve is made up of valve body, valve pocket, spool, fairlead, spring and electric magnet, here valve pocket is pressed in the valve body, spool is packed in the valve pocket, respectively adorn a fairlead at the valve pocket two ends, spring one end is enclosed within on the fairlead, the other end is enclosed within on the push rod of electric magnet, and electric magnet is done in order to spool by fairlead, to realize the oil circuit commutation; And hydraulic control one-way valve is by plug screw, combined seal ring, piston, back-moving spring, nonreturn valve core, packing ring, spring, guider screw and pad are formed, wherein nonreturn valve core is installed in the valve opening on the valve body, packing ring is contained in the right-hand member of nonreturn valve core, spring and pad are enclosed within on the guider screw, and guider screw is from valve opening right-hand member screw-in and makes the fore-end of screw pass pad, spring, packing ring is in the right side of nonreturn valve core, back-moving spring is packed in the spring cavity, the piston right-hand member inserts in the back-moving spring, the piston left end contacts with plug screw, and plug screw screws in the valve opening by combined seal ring piston seal is fixed.
The reversal valve that designs and produces according to technique scheme compared with prior art, its advantage is that it not only has the basic function and the technical characterstic of common solenoid directional control valve, but also have volume little, from heavy and light, sensitive reversing, long service life, plurality of advantages such as easy for installation.
Four, description of drawings
Fig. 1. operating-table electromagnetism integrated change valve structural representation;
Fig. 2. operating-table electromagnetism integrated change valve user mode figure.
Five, the specific embodiment
Operating-table of the present utility model can be implemented according to Fig. 1, mode shown in Figure 2 with the electromagnetism integrated change valve: as shown in Figure 1, it is to be contained on the same valve body by two identical in structure solenoid directional control valves and a hydraulic control one-way valve to combine.Wherein solenoid directional control valve is made up of valve body 1, valve pocket 2, spool 3, fairlead 4, spring 5 and electric magnet 6, here valve pocket 2 is pressed in the valve body 1, spool 3 is packed in the valve pocket 2, respectively adorn a fairlead 4 at the valve pocket two ends, spring 5 one ends are enclosed within on the fairlead 4, and the other end is enclosed within on the push rod of electric magnet; And hydraulic control one-way valve is by plug screw 7, combined seal ring 8, piston 9, back-moving spring 11, nonreturn valve core 12, packing ring 13, spring 14, guider screw 15 and pad 16 are formed, wherein nonreturn valve core 12 is installed in the valve opening on the valve body 1, packing ring 13 is contained in the right-hand member of nonreturn valve core 12, spring 14 and pad 16 are enclosed within on the guider screw 15, and guider screw 15 is from valve opening right-hand member screw-in and makes the fore-end of screw pass pad 16, spring 14, packing ring 13 is in the right side of nonreturn valve core, back-moving spring 11 is packed in the spring cavity, piston 9 right-hand members insert in the back-moving spring, the piston left end contacts with plug screw 7, and plug screw 7 screws in the valve opening piston 9 sealing and fixing by combined seal ring 8.
When working with the electromagnetism integrated change valve according to the operating-table of said structure form composition: when the right electric magnet was switched on, solenoid directional control valve control oil circuit directive effect was in the spring cavity of piston nose, and oil pressure is pushed nonreturn valve core open in the spring cavity; When two electric magnet were not all worked, solenoid directional control valve was in meta, and check valve is in closed condition and plays the pressurize effect; When left side electric magnet was switched on, oil pressure acted on piston rear end, and piston overcomes spring pressure, and with one-way valve opens, oil pressure is replied initial state.
