Description
Technical field
The utility model relates to a kind of hydraulic diaphragm pump, especially a kind of control valve assembly of hydraulic diaphragm pump.
Background technique
Existing hydraulic diaphragm pump is because there is defective in the structural design of the control valve assembly that existing hydraulic diaphragm pump gets usually because cross the diaphragm that repairing causes damaging hydraulic diaphragm pump.
The model utility content
It is high and prevent diaphragm because cross the control valve assembly that repairing causes the hydraulic diaphragm pump that damages that the purpose of this utility model provides a kind of measuring accuracy.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of control valve assembly of hydraulic diaphragm pump comprises guide sleeve, gate, spring, back-up ring, liquid cylinder, and described guide sleeve is installed on the axle of gate, on the axle of gate back-up ring is installed, and between guide sleeve and the gate spring is installed; Back-up ring is contained on the guide sleeve and with liquid cylinder and matches, and the diameter of the intermediate portion of the axle of described gate is less than both sides, and the intermediate portion of the axle of gate is corresponding with the hole of guide sleeve.
O shape circle, O shape circle are housed respectively on the described guide sleeve.
The length of described guide sleeve is less than the length of the axle of gate.
One end of the axle of described gate stretches in the normal pressure oil of liquid cylinder.
Described liquid cylinder has passage, and the normal pressure oil phase of passage and liquid cylinder is logical.
The beneficial effects of the utility model are: the utility model measuring accuracy height, and prevent that diaphragm from causing damaging because of crossing repairing.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, control valve comprises guide sleeve 1, gate 2, back-up ring 4, valve spring 5, back-up ring 6, O shape circle 7, O shape circle 8, liquid cylinder 9, and described guide sleeve 1 is installed on the axle of gate 2, between guide sleeve 1 and the gate 2 spring 5 is installed, and uses back-up ring 4 fixing; Back-up ring 6 is contained on the guide sleeve 1 and with liquid cylinder 9 and matches, and the diameter of the intermediate portion of the axle of described gate 2 is less than both sides, and the intermediate portion of the axle of gate 2 is corresponding with the hole 11 of guide sleeve 1.The length of guide sleeve 1 is less than the length of the axle of gate 2.One end of the axle of described gate 2 stretches in the normal pressure oil of liquid cylinder 9.Described liquid cylinder 9 has path 10, and the normal pressure oil phase of path 10 and liquid cylinder 9 is logical.Back-up ring 6, O shape circle 7 and O shape circle 8 are contained in respectively on the guide sleeve 1, and the The whole control valve is contained on the liquid cylinder 9.
Control valve is to move product, and its course of action is: metering pump is when suction stroke, and hydraulic pressure cavity pressure reduces, and Fill valve is opened, and hydraulic oil enters control valve by the oil circuit on the liquid cylinder 9, can't enter hydraulic pressure cavity, can prevent the generation of repairing like this.Have only the diaphragm 3 of working as to move backward, when shake-up gate 2 slides backward, just can open the oil circuit between control valve and hydraulic pressure cavity, make oil subsidy in hydraulic pressure cavity, realize correct repairing.Guaranteed measuring accuracy, and prevented that diaphragm from causing damaging because of crossing repairing.
Claims (5)
