Abstract
The utility model discloses a multifunctional leak-off control valve set which is mainly used for being arranged on an electric operation table to control the work status of the operation table. The multifunctional leak-off control valve set is composed of an overflow valve, a check valve, an oil filter, an electromagnetic directional valve, electromagnetic stop directional valves, oil cylinders, etc., which are combined according to the need of the operation status. Two electromagnetic stop directional valves are used for performing bidirectional control of one oil cylinder, one electromagnetic stop directional valve is used for performing unidirectional control of the other oil cylinder, and the functional controls of the operation such as forward-backward inclination, leftward-rightward inclination, backward press, elevation, locking, etc. can be accomplished through the combination of the bidirectional control and the unidirectional control. The multifunctional leak-off control valve set, due to the adoption of the electromagnetic stop directional valves and the insertion type structure, has the advantages of no leakage, pressure protection at any positions, insertion structure, small size and so on, apart from the satisfaction in the function as an operation table, and is an upgrading product of the prior control valve sets of the electromagnetic directional valve type.
Description
One, technical field
This utility model relates to a kind of control valve, particularly relates to a kind of multifunctional control valve group.
Two, background technology
Control valve group commonly used when controlling the multistation state on the motor-driven operating table at present, and the common electromagnetic valve of the general employing of the control valve in the control valve group are with the state of control operating-table.Practice shows adopts the duty of solenoid control operating-table to have many defectives, often have as: 1, the resting state of the operating-table position of often leading owing to the matched in clearance of electromagnetic valve changes in the course of the work, make the state control of operating-table unreliable, unstable, the operation of leading when serious makes mistakes.2, No. 45 steel of the general employing of existing control valve group pedestal influence surface cleanness because of getting rusty; 3, the electromagnetic valve volume is huge, and inconvenience is installed, under ad hoc structure even can't install; 4, electromagnetic valve is because all there is leakage in reasons in structure.Must study, develop a kind of leak free control valve group for above-mentioned reasons.
Three, utility model content
The purpose of this utility model is to provide a kind of Multifunction that can overcome the existing many defectives of employing electromagnetic valve valve group not have the leak control valve group.This multifunction non-leakage control valve group can adopt following technical scheme to implement: it partly is made up of overflow valve, check valve, oil filter, solenoid directional control valve, electromagnetism cut-off type reversal valve, oil cylinder etc.Wherein overflow valve, check valve, oil filter, solenoid directional control valve are to be coupled to each other successively, solenoid directional control valve left end output circuit connects with the input of the DT1, the DT3 that control oil cylinder, DT5, DT8, DT9 respectively, and the right-hand member of solenoid directional control valve connects with DT2, DT4, the DT7 of control oil cylinder respectively.What is called DT is meant electromagnetism cut-off type reversal valve, and so-called the connection refers to that all oil circuit connects (down together).The output of DT1 connects the input of anteversion and retroversion oil cylinder, and the output of anteversion and retroversion oil cylinder connects the input of DT2.Control the duty of anteversion and retroversion oil cylinder like this by solenoid directional control valve, electromagnetism cut-off type reversal valve DT1, DT2, that is the forward and backward duty of inclining of control motor-driven operating table.According to same principle, the input and output side of the oil cylinder that inclines about DT3, DT4 connect respectively, the duty of the oil cylinder that inclines about control; DT5, DT7 connect the input and output side of back pressure oil cylinder respectively, with the duty of control back pressure oil cylinder, are connected in series a DT6 between DT5 and back pressure oil cylinder, its objective is in order to prolong pressure maintaining performance; The output termination hoist cylinder of DT8 is with the rising of control oil cylinder, the equipment self-weight of the decline of oil cylinder by joining with it; The input of the output termination locked cylinder of DT9.
The multifunction non-leakage control valve group of forming according to technique scheme compared with prior art, its advantage is: 1, the control valve in the control valve group adopts electromagnetism cut-off type reversal valve, two-way nothing is leaked and the characteristics of the equal pressurize in optional position but have, and has improved stability, the reliability of duty; 2, all valves all adopt the plug-in structure in the control valve group, and volume greatly reduces, and structure is compact more.
Four, description of drawings
Fig. 1, multifunction non-leakage control valve group structural representation.
Five, the specific embodiment
In conjunction with the accompanying drawings this utility model is further described down.
As shown in Figure 1, multifunction non-leakage control valve group is made up of overflow valve, check valve, oil filter, solenoid directional control valve, electromagnetism cut-off type reversal valve, oil cylinder, wherein overflow valve, check valve, oil filter, solenoid directional control valve input 3 are to be coupled to each other successively, the left end 1 of solenoid directional control valve connects with electromagnetism cut-off type reversal valve DT1, DT3, DT5, DT8, the DT9 input 1 of control oil cylinder respectively, the right-hand member 2 of solenoid directional control valve connects with electromagnetism cut-off type reversal valve DT2, DT4, the DT7 of control oil cylinder respectively, and so-called the connection refers to that all oil circuit connects.The output of DT1 connects the input 12 of anteversion and retroversion oil cylinder, the output of anteversion and retroversion oil cylinder connects the input 21 of DT2, the input and the outfan of oil cylinder incline about DT3, DT4 connect respectively, DT5, DT7 connect the input and the outfan of back pressure oil cylinder respectively, between DT5 and back pressure oil cylinder, be connected in series a DT6, the output termination hoist cylinder of DT8, the input of the output termination locked cylinder of DT9.
When working according to the multifunction non-leakage control valve group of said structure composition, at first through the overflow valve adjust blood pressure, pass through check valve behind the set pressure, oil filter enters solenoid directional control valve, solenoid directional control valve left end commutation energising, oil circuit 1 arrives DT1 respectively, DT3, DT5, DT8, the input 1 of DT9, electromagnetism cut-off type reversal valve DT1 energising, oil arrives 12 ends of anteversion and retroversion oil cylinder through 11 ends of DT1, oil cylinder rises, DT2 also switches in the DT1 energising, then the oil in the anteversion and retroversion oil cylinder returns 2 ends of solenoid directional control valve through 21 ends of 22 arrival DT2, finishes the vertical motion of anteversion and retroversion oil cylinder.When DT1, DT2 while dead electricity, but oil cylinder all pressurizes at an arbitrary position, and as DT1, DT2, when solenoid directional control valve was switched on simultaneously, oil cylinder descended.About the incline operating principle of oil cylinder, back pressure oil cylinder identical with the anteversion and retroversion oil cylinder.Hoist cylinder is an one-way cylinder, the DT8 energising, and oil cylinder rises, and as dead electricity, optional position pressurize, the decline of hoist cylinder descend automatically by the deadweight of equipment.The operating principle of locked cylinder is identical with hoist cylinder.
