Abstract
The invention relates to a digital control flow valve, which adopts digital control and is high in resolution and good in reliability and working stability. The valve comprises a valve body and a valve core, and is characterized in that the valve also comprises a stepping motor and a valve jacket; a gear of the stepping motor is connected with the valve core through a sector tooth; the valve jacket is sleeved outside the valve core; the valve jacket is arranged on the valve body; the stepping motor is in electronic control connection with the valve core; an oil passing groove is arranged on the valve core; and a T-shaped groove is arranged on the valve jacket.
Description
(1) technical field
The present invention relates to hydraulic flow control technique field, be specially digital controlled flux valve.
(2) background technique
With the normally hydraulic control of cement dead load compression testing machine, in use, need the flow of control hydraulic oil, all be artificially to control hydraulic fluid flow rate in the past, thereby controlled rate of loading that error is big by manually operated valve.
(3) summary of the invention
At the problems referred to above, the invention provides digital controlled flux valve, it adopts digital control, resolution height, reliability and good operating stability.
Its technological scheme is such: it comprises valve body, spool, it is characterized in that: it also comprises stepper motor and valve pocket, the gear of described stepper motor is connected with spool by the fan tooth, described valve pocket is set in described spool outside, described valve pocket is installed on described valve body, described stepper motor and spool electricly connect, and have oil groove on the described spool; Have T type groove on the described valve pocket.
It is further characterized in that: described stepper motor is connected with described valve body by connecting plate.
Apply the present invention to cement dead load compression testing machine, its beneficial effect is: it adopts digital control approach control hydraulic fluid flow rate, precision height, reliability and good operating stability.
(4) description of drawings
Fig. 1 is a structural front view of the present invention;
Fig. 2 is the side view cutaway drawing of Fig. 1;
Fig. 3 is described valve pocket T type slot cross-section schematic representation;
Fig. 4 crosses the tank structure schematic representation for described spool;
Fig. 5 crosses oil groove end-face structure schematic representation for described spool.
(5) embodiment
See Fig. 1, the present invention includes valve body 6, spool 4, also comprise stepper motor 1 and valve pocket 5, stepper motor 1 is connected with valve body 6 by connecting plate 7, and the gear 2 of stepper motor 1 is connected with spool 4 by fan tooth 3, and valve pocket 5 is set in spool 4 outsides, valve pocket 5 is fixed in the valve body 6, stepper motor 1 electricly connects with spool 4, and spool 4 outer circumferential faces had oil groove 8, and the valve pocket inner peripheral surface has T type groove 9.
During work, the hydraulic fluid flow rate of digital stream metered valve is controlled by the cooperation of crossing the T type groove 9 on oil groove 8 and the valve pocket 5 on the spool 4, stepper motor 1 continuous reception test machine control signal rotation, spool 4 rotates under the drive of stepper motor 1, and the oil groove 8 excessively of spool 4 has determined the size of flow with respect to the T type groove 9 formed openings of sizes on the valve pocket 5 that is fixed on valve body 6 inside.
Claims (2)
