Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
The utility model relates to one and gets China ink on-off valve device, it comprises ink feed mouth 1, valve body (black chamber) 2, dunnage 3, Compress Spring 4, pressing plate 5, bearing 6, the first balancing lever 7, the second balancing lever 8, the first bearing pin 9, the second bearing pin 10, the second valve rod 11, the first valve rod 12, the second ink outlet mouth 13, the first ink outlet mouth 14, the second seal ring 15, the first seal ring 16, as shown in Figures 1 to 3.
The China ink on-off valve device of getting of the present utility model, fixes by dunnage 3 and peripheral unit, and valve body 2 is fixed on the bottom of dunnage 3.Valve body 2 is Jimo chamber also, and ink feed mouth 1 is connected on the sidepiece of valve body 2 by screw thread, is communicated with the inner chamber of valve body 2; The second ink outlet mouth 13, the first ink outlet mouth 14 are also threaded connection the bottom that is fixed on valve body 2, are also communicated with the inner chamber of valve body 2.The second valve rod 11,12 of the first valve rods are arranged on the inside of valve body 2, both lower ends are relative with the ink outlet port of the second ink outlet mouth 13, the first ink outlet mouth 14 respectively, clogging ink outlet port when nature, both upper ends connect respectively the second balancing lever 8 and the first balancing lever 7.Further preferably, in the groove on valve rod, arrange by seal ring (not shown) and leak to prevent ink.
Two groups of identical valve rod operation mechanisms are being set in dunnage 3, are respectively arranging a set ofly corresponding to first, second valve rod, object is the lifting that is respectively used to control the first valve rod and the second valve rod.Each group comprises a bearing 6, and bearing 6 is fixed on dunnage 3 tops; Pressing plate 5 is articulated on bearing 6 by bearing pin 9, and pressing plate 5 can swing around bearing pin 9 on bearing 6.In a side of pressing plate 5, offering ellipse hole 17, as shown in Figure 4, balancing lever (first, second balancing lever is contained in respectively on a set of pressing plate), lower end is connected valve rod through dunnage 3 with valve body 2, upper end is through in ellipse hole 17, and be connected on pressing plate 5 by bearing pin 10, on pressing plate, ellipse hole is offered in this position, balancing lever can swing around bearing pin 10 in the elliptical aperture of pressing plate, the design of elliptical aperture is the swing space in order to reserve balancing lever head so that balancing lever bottom in course of action all the time in the lifting of vertical state band ovable valve stem.In the bottom blind hole of the opposite side of pressing plate 5, connecting Compress Spring 4, the lower end of Compress Spring 4 is fixed in the spring groove in dunnage 3.Compress Spring 4 and balancing lever are respectively in the both sides of bearing 6.
The first balancing lever 7, the second balancing lever 8 can connect respectively the first valve rod 12 and the second valve rod 11 (as shown in Figure 5) by screw thread, and the effect of balancing lever is the length accuracy that makes up valve rod, reduce valve rod processing request.In the time that pressing plate 5 is rotated in slotted eye around bearing pin 9 by external force, drive the valve rod being fixed on balancing lever to realize and move up and down 2 li of valve bodies.Also can consider to design the lengthening section (flexible rod belongs to prior art not to be done too much and repeat) of shrinking structure here on balancing lever.
Further, sleeve can be set around valve rod hole, protection balancing lever, and there is dustproof effect.
This operation mechanism is actual is to adopt lever principle design, Compress Spring 4 and balancing lever rank the both sides of bearing 6, bearing 6 is equivalent to fulcrum, in the situation that spring one side applies external force, pressing plate 5 is rotated around bearing pin 9 by external force, and the valve rod on the balancing lever of drive opposite side moves up and down in valve body, in the time of Compress Spring, valve rod rises, and in the time of release or extension spring, valve rod declines.Structure under this lever principle, the application of force can be completed by cylinder, and the cylinder bar of cylinder touches in the position, upper top of spring or is also passable near spring one side.And under nature, due to Compress Spring effect, by pressing plate 5 make balancing lever with valve rod fixed thereon in valve body lowest positions, now valve rod is just blocked respectively ink outlet port.
At the ink outlet port place of two ink outlet mouths, the second seal ring 15 and the first seal ring 16 can be respectively set, flexible seal ring can ensure between valve rod and ink outlet port, to have flexible contact, and there is good sealing to prevent fluid seepage, dismantle in addition seal ring and clean black mouth all very convenient.The bore of first, second seal ring is corresponding with corresponding ink outlet mouth size, the first ink outlet mouth 14 is joined the first seal ring 16, the second ink outlet mouth 13 is joined the second seal ring 15, the first valve rods 12, the second valve rod 11 corresponds respectively to the first ink outlet mouth 14 and the second liquid outlet 13.Owing to being used in high viscosity liquid, valve rod is selected metal valve stem the best.
The utility model is preferentially selected spring and lever structure, and this is because the buffer function of spring can make the steadily lifting slowly of driven valve rod, realizes fluid flow under valve control accurately controlled with this.
The utility model design is large, the object of little two valve rod co-ordinations is for liquid with precise control flow, rely on this valve arrangement, can realize fast, get liquid mode for slow two kinds, while starting quantitative China ink, external equipment passes through the ink in China ink bucket in the inner chamber of ink feed mouth 1 pumping inlet valve body 2, at the beginning of getting liquid, while not needing accurately to control liquid outlet quantity, can open the first ink outlet port of the first valve rod below, allow the large flow of liquid flow out fast, in the time closing on taken amount limit value, close the first ink outlet port, open the second ink outlet port of the second valve rod below, allow liquid small flow slowly flow out, can preset large, the critical value of little taken amount, while arriving critical value value, automatically close the first ink outlet port, open the second ink outlet port, such as getting the liquid of 100 grams, can set critical value is 90 grams, in the time that the measuring apparatus of the first liquid outlet below measures flow to 90 gram, stop immediately the fluid of the first liquid outlet, and open the second liquid outlet, everything can be realized automatically by the action of computer control valve rod operation mechanism cylinder.Measuring apparatus is placed in on-off valve device below, the black weight of can Real-time Obtaining receiving, and black numerical quantity is fed back to relevant device control match mechanism apply active force to pressing plate 5.
