Abstract
The utility model discloses a multi-purpose triple valve of a haemodialysis machine, which mainly comprises a base, a switch knob and three joints, wherein the interior of the base is provided with a spacing ring; the opening and closing of the three joints are controlled by the position of a gag lever post on a spacing groove in the spacing ring; the middle part of the base is vertically provided with a through hole in which the switch knob is installed, and the axle of the switch knob is arranged in the through hole in a clearance fit manner; the side wall of the base is transversely provided with three screwed holes respectively communicated with the through hole; and the joints connected with the liquid inlet/outlet pipe are respectively fixed to the screwed holes in a screw joint mode. The triple valve can realize free switching to control the liquid outlet direction by full-opening, full-closing or opening and closing. The multi-purpose triple valve has the advantages of convenient operation, simple structure and low fault rate.
Description
Technical field
This utility model relates to the three-way valve of using of a kind of valve, particularly a kind of haemodialysis control unit more.
Background technology
Select control ultrafiltration test or pumping equipment many at present in the haemodialysis control unit in the medical apparatus and instruments based on electromagnetic valve, though this type of valve does not need manually-operated, but in actual use, these valves are less because of the aperture, be easy to obstruction and cause ultrafiltration inaccurate, influence patient's dialysis quality, can cause the ultrafiltration outlet conduit to break during fault and make the equipment can't operate as normal.
The utility model content
The purpose of this utility model is to disclose a kind of simple in structure, and is easy to operate, can effectively avoid the problems referred to above haemodialysis control unit use three-way valve more.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of three-way valve of using of haemodialysis control unit more, mainly comprise pedestal, switch knob and three joints, described pedestal middle part vertically has the through hole that switch knob is installed, and the axle of switch knob places this through hole internal clearance to cooperate; The sidewall of pedestal laterally has three screwed holes that are communicated with through hole respectively, with advance/joint that drain pipe is connected spins respectively and is fixed on the screwed hole.
Base interior is provided with spacing ring, and spacing ring is provided with stopper slot, and the axle and the corresponding position of this spacing ring of switch knob are fixed with gag lever post, and gag lever post just in time places on this spacing intra-annular stopper slot and is slidingly matched.
Have three pod apertures that are interconnected on the described axle that places the switch knob in the pedestal, described pod apertures is relative with three screwed holes on the pedestal respectively.Three direction signs are arranged above the described switch knob, and described sign is corresponding with three pod apertures on the switch knob axle.
Three screwed holes are on the same horizontal plane, and the angle angle between at least two adjacent joints is identical.Angle between the described joint is 90 °.
Three pod apertures and three screwed holes are in the same plane.
Can realize that standard-sized sheet, complete shut-down or two open a free switching controls fluid direction of closing.
Of the present utility model easy to operate, simple in structure, function is many, fault rate is little, convenient for installation and maintenance, with low cost, stable performance has effectively been avoided the ultrafiltration outlet to block and has been caused the harm of the inaccurate or pipeline breaking of ultrafiltration.
