Abstract
The utility model discloses a multifunctional distribution valve for a tissue dehydrator. A valve cover is installed on the valve body and is provided with a valve shaft, one end of the valve shaft is connected with a driving mechanism, and a liquid inlet is arranged at the other end of the valve shaft. The valve shaft is internally provided with a liquid channel which is internally provided with a hollow collecting rod. Exposed end of the hollow connecting rod extends outside into a cavity between the valve cover and the valve body and is externally wrapped by a magnetic separation cover. A liquid outlet is arranged at the exposed end of the hollow connecting rod. The valve body is provided with 15 liquid distribution holes corresponding to 15 liquid systems, and the 15 liquid distribution holes are distributed along the circumferential surface of the valve body corresponding to the liquid outlet of the hollow connecting rod. The multifunctional distribution valve for the tissue dehydrator has the advantages of reasonable mechanism, accurate positioning and displacement seal. In the valve, only cross section of the magnet is contacted with the local plane of the valve body to meet air work pressure of 0.4 kilograms per square centimeter with the utilization of the magnetic induction generated by the magnet.
Description
Technical field
The utility model relates to a kind of multifunction organization Haug drainer distributing valve.
Background technique
The function of distributing valve is that the used variable concentrations of Haug drainer, heterogeneity chemical reagent are switched transmission.Performance requirement freely, reaches moving again and is bordering on sealing state with quiet matching surface in the time of should reaching moving and quiet matching surface rotation during switching, therefore says that it is a vitals of full-automatic totally-enclosed tissue processor.Up to the present, domestic and international full-automatic totally-enclosed tissue processor distributing valve, generally exception all is to adopt moving plate, coincide with the still integral planar, so, under the working pressure situation, surface friction drag greater than, easily sting valve, do not reach switching function; Greater than alcohol, xylene solution molecular diameter, alcohol, xylene solution then very easily take place to go here and there mutually moving, cause the reduction of monomer solution purity, effect to reduce as if the surface of contact matching gap.To this, distributing valve will be accomplished precision like this, and is by no means easy.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanism reasonable, the multifunction organization Haug drainer distributing valve of favorable working performance.
Technical solution of the present utility model is:
A kind of multifunction organization Haug drainer distributing valve, it is characterized in that: comprise valve body, adorn valve gap on the valve body, adorn the valve shaft that an end is connected with driving mechanism in the valve gap, the other end of valve shaft is provided with liquid entering hole, fluid passage is set in the valve shaft, connecting rod is set in the fluid passage, the bared end of connecting rod stretches out in the chamber between valve gap and valve body, and bared end is surrounded by magnetic shield outward, and the bared end of connecting rod is provided with liquid outlet opening, and valve body is provided with ten five liquid distribution apertures corresponding respectively with 15 kinds of liquid systems, and 15 dispensing orifices distribute along the valve body circumferential surface, and the position of circumferential surface is corresponding with the position of connecting rod liquid outlet opening.
On valve gap, be provided with optoelectronic switch.
The utility model mechanism is reasonable, can reach accurate location, the displacement sealing; This valve has only the magnet cross section to contact with the valve body part plan, the magnetic induction intensity that utilizes magnet to produce, in the time of can reaching axial displacement, magnet cross section and valve body kinetic friction resistance are less than motor driving power, the magnetic induction intensity that utilizes magnet to produce, magnet cross section and valve body part plan are inhaled together all the time, satisfied 0.4 kg/cm air working pressure.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
A kind of multifunction organization Haug drainer distributing valve, comprise valve body 2, dress valve gap 1 on the valve body, adorn the valve shaft 3 that an end is connected with driving mechanism in the valve gap, the other end of valve shaft is provided with liquid entering hole 17, fluid passage 10 is set in the valve shaft, connecting rod 5 is set in the fluid passage, the bared end of connecting rod stretches out in the chamber between valve gap and valve body, and bared end is surrounded by magnetic shield 6 outward, and the bared end of connecting rod is provided with liquid outlet opening 22, and valve body is provided with ten five liquid distribution apertures 12 corresponding respectively with 15 kinds of liquid systems, and 15 dispensing orifices distribute along the valve body circumferential surface, and the position of circumferential surface is corresponding with the position of connecting rod liquid outlet opening 22.On valve gap, be provided with optoelectronic switch.Also have hubcap 4, magnet 7, seal ring 8, bearing 9, hubcap fixed hole 11, valve gap and valve body attachment hole 13, bearing 14, optoelectronic switch mounting hole 15, seal ring 16, U type groove 18, seal ring 19, set screw 20, screw 21 among the figure.
