Abstract
The invention discloses a quantitative filling device and relates to a quantitative filling device for various kinds of liquid matters. With mercury filling of a mercury sphygmomanometer as an example in the embodiment of the invention, the quantitative filling device comprises a valve seat, a valve plug, a base plate, a cylinder, an adjusting screw, an input-output hose and a mercury cup, wherein the valve plug is provided with a quantitative groove, therefore, the quantity of mercury filled in each mercury sphygmomanometer is definite; and the valve plug is arranged inside the valve seat, and the valve plug and the valve seat are matched with high precision, therefore, the mercury does not leak. The valve seat is fixed on the base plate, the cylinder is fixed on the base plate, and the valve plug moves back and forth under the drive of the cylinder. The mercury cup is arranged at the upper part of a filling unit, the mercury is introduced into the valve plug through a rubber pipe, meanwhile, the cylinder is controlled by adopting a single chip microcomputer, the time of staying before and behind the valve plug can be set, and the intelligentizing degree of the quantitative filling device can be greatly improved.
Description
Technical field
The present invention relates to a kind of can be to various fluents at the equipment that carries out quantitative filling, especially a kind of equipment that mercurial sphygmomanometer is carried out to mercury quantitative filling.
Background technology
On mercurial sphygmomanometer manufacturing line, at filling this procedure of mercury, still take manually to use the mode of hopper filling mercury at present.Which technique is outmoded, and production efficiency is low, and mercury is a kind of material of highly volatile, and human body sucks excessive meeting and causes mercurial poisoning, and therefore, the flowing power of the operating personal of this operation is very large.Meanwhile, artificial when filling, each filling amount is all different, thereby cause lower road to check and approve operation, will waste time and energy.
Summary of the invention
Object of the present invention adopts quantitatively, seals without leaky design, guarantees that the filling amount of each mercury is consistent, realizes personnel and the operation of mercury no touch, and simplify working process, raises the efficiency, and improves working environment.
Filling mercury work efficiency, the problem that filling amount conformability is poor, technique falls behind, the technical solution adopted for the present invention to solve the technical problems is: the present invention includes valve seat, spool, substrate, cylinder, set screw, input and output flexible pipe, mercury cup.Spool is loaded on valve seat inside, and it is high that both quality of fits are wanted, and valve seat and cylinder are all fixed on substrate, and spool and cylinder axis are fastenedly connected, and mercury cup is placed in filling machine top, by India rubber tube, mercury is introduced in spool.Described seat material is non-metallic material, and valve seat inside has a through hole, and valve seat top has three apertures, and valve seat below has an aperture.Three described apertures are communicated with valve seat endoporus, and valve seat below aperture is also communicated with valve seat endoporus.Described spool has certain measuring tank, and it is concentric with the hole of valve seat below that the bottom of groove has a hole.
Beneficial effect of the present invention is mainly manifested in: first-time qualification rate brings up to 98% by 70%, and unit time production efficiency improves 20%, can also realize the no touch operation of operating personal and mercury simultaneously, reduces labour intensity.
Accompanying drawing explanation
Fig. 1 is the mercurial sphygmomanometer filling apparatus schematic diagram of the embodiment of the present invention.
Fig. 2 is that the mercury of the embodiment of the present invention enters spool position figure.
Fig. 3 is that the mercury of the embodiment of the present invention goes out spool position figure.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described.
As shown in Figure 1, a kind of mercurial sphygmomanometer filling apparatus, it comprises plumbous bucket 1, switch 2, mercury cup 3, calibration gauge 4, filling machine 5.Mercury energy and various metals react, but do not react with plumbous and plastics, so material therefor of the present invention is lead and plastics.Plumbous bucket 1 is for storing mercury in transportation, general volume is all larger, lead bucket 1 is drawn to an outlet, there is a switch 2 in exit, by a plastic pipe mercury, flow in mercury cup 3, a calibration gauge 4 is equipped with in mercury cup 3 sides, by this flow counter, can know the amount of mercury in mercury cup 3, the lower end of mercury cup 3 has flatly, by a rubber tube, be connected with the water inlet silver hole 7 of valve seat in filling machine 5, the mercury hole that goes out of valve seat is connected with the mercurial column of mercurial sphygmomanometer by a rubber tube.
As shown in Figure 2, the present embodiment passes through air cylinder driven, in operating process, only with foot-operated switch, cylinder is moved and controlled, spool only has two positions under the driving of cylinder, and mercury enters spool position (shown in Fig. 2) and mercury goes out spool position (shown in Fig. 3), and mercury enters in spool from hole 7, groove 11 is filled with, one deck resistance mercury paper is loaded onto at 10 ends of hole, and it can stop mercury to be emerged from hole 10, but the air in groove can see through from resistance mercury paper.Bolt 9 is used for the volume size of regulating tank 11, thereby can finely tune the amount of each filling mercury.
After foot-operated switch is stepped on, air cylinder driven valve core movement is to going out mercury position, as shown in Figure 3, mercury in spool groove will flow out by hole 12 and hole 13, and at this moment, hole 7 does not communicate with groove 11, mercury enters not go, amount of mercury just can not change, and hole 10 communicates with groove 11, and air enters in groove by hole 10.The present invention is by the control of foot-operated switch, thereby realizes the filling of mercury.
Above, be only that the preferred embodiment for the present invention is described; not the spirit and scope of the present invention are limited; do not departing under the prerequisite of design philosophy of the present invention; in this area, common engineering staff, as the kind of liquid in technical scheme of the present invention and valve body shape change, all should belong to protection scope of the present invention.
