Abstract
The utility model relates to a stopping flow control valve for respirators, which belongs to the medical respirator field. The stopping flow control valve comprises an outer shell, and an electromagnetic coil which is fixed in the interior of the rear end of the outer shell and is connected with a controller, wherein, the rear end of the electromagnetic coil is provided with a rear cover. The utility model is characterized in that the front end of the outer shell is connected with an exhalation valve joint with a liquid passage; an exhalation shaft is arranged in the electromagnetic coil; the rear end of the exhalation shaft is connected with a spring return mechanism; a stopping body with diameter larger than that of an inner hole of the exhalation valve joint is arranged between the front end of the exhalation shaft and the exhalation valve joint. Since the utility model uses the electromagnetic coil to drive the exhalation shaft to control the circulation or the closing of liquid; the stopping flow control valve has the advantages of stable and reliable performance, high precision, simple structure and low cost. Furthermore, the connection between the exhalation valve joint of the utility model and the outer shell, and between a top cap and the exhalation shaft is demountable connection; the cleaning and the disinfection of the exhalation valve joint and the top cap are made to be more convenient.
Description
Technical field
This utility model belongs to medical respirator field, is specifically related to a kind of flow control valve of respirator.
Technical background
In the prior art, be applied in the respirator in the clinical treatment, the open and close controlling of its flow is generally taked the mode with solenoid controlled scissors-type support.Push by the folding of scissors-type support during work and be connected with fluidic flexible pipe.Although this kind control mode is simple and convenient, performance is unreliable, causes the inaccurate of fluid control easily, and it is unfavorable to bring for patient's treatment.
The utility model content
This utility model provides a kind of and can accurately control fluidic circulation or close and the respirator flow blocking type control valve of dependable performance.Its technical scheme that adopts is: design a kind of respirator blocking type flow control valve, comprise shell and be fixed on the solenoid that outer casing back is inner and link to each other with controller, the rear end of solenoid is provided with bonnet, it is characterized in that the front end connection one of shell has the outlet valve joint of fluid passage, the axle of exhaling is set in the solenoid, the rear end of expiration axle connects spring reset mechanism, between the front end of the axle of exhaling and the outlet valve joint the stifled body of diameter greater than outlet valve joint endoporus is set.
This utility model to offering endoporus, offering the cannelure of ladle cover endoporus at its other end, is offered the through hole that communicates with cannelure along an end central longitudinal of outlet valve joint along the outer periphery of outlet valve.Spring cup, spring cup are set in the bonnet connect firmly together by the screw and the axle of exhaling, between spring cup inwall and the bonnet inwall spring is set, spring housing is contained in a rear end of exhaling spool.The front end socket one top medicated cap of expiration axle is provided with the flexible sheet of diameter greater than outlet valve joint endoporus between top medicated cap and the outlet valve joint.Connecting between outlet valve joint and the shell is that clamp-close type connects.
This utility model has been owing to adopted the solenoid axle of drive exhaling to control fluid flow or close, thereby stable and reliable for performance, precision height, simple in structure, low cost of manufacture; And, between outlet valve joint of the present utility model and the shell, the top medicated cap is removable connection with the connecting between the axle of exhaling, and makes that the cleaning and sterilizing of outlet valve joint and top medicated cap is more convenient.
Description of drawings
Fig. 1 is the structural representation of the fluid flow state of an embodiment of this utility model;
Fig. 2 is the structural representation of this utility model fluid off-state;
The specific embodiment
As shown in the figure: the front end of shell 4 connects an outlet valve joint 9, to offering endoporus 7, offering the cannelure 8 of ladle cover endoporus 7 at its other end, offers the through hole 10 that communicates with cannelure along an end central longitudinal of outlet valve joint 9 along the outer periphery of outlet valve.The inside, rear end of shell 4 is provided with solenoid 12, and the rear end of solenoid 12 is provided with bonnet 2, and spring cup 1 is set in the bonnet 2, and spring cup 1 is fixed together by the screw and the axle of exhaling.The axle 5 of exhaling is set in the solenoid, and the front end of the axle 5 of exhaling connects top medicated cap 11, and the flexible sheet 6 of diameter greater than outlet valve joint endoporus 7 is set between top medicated cap 11 and the outlet valve joint 9.
When switching in the solenoid 12, the axle 5 of exhaling moves forward under the effect of electromagnetic field, driving top medicated cap 11 moves ahead, reduce gradually in gap between top medicated cap 11 and the flexible sheet 6, at last, the top medicated cap is pressed in flexible sheet 6 on the endoporus 7 of outlet valve joint 9 tightly, makes fluid not flow to through hole 10 from endoporus 7, thereby has played sealing function well.
When cutting off the power supply in the solenoid 12, the axle 5 of exhaling is devolved the position after under the elastic force effect of spring 3, drives top medicated cap 11 and retreats, and the gap between top medicated cap 11 and the flexible sheet 6 becomes greatly gradually, and fluid just flows to through hole 10 from endoporus 7.
Solenoid 12 of the present utility model links to each other with controller, controls the break-make of electric currents in the solenoid 12 by controller, controls the break-make of outlet valve joint 9 inner fluids afterwards.By the checker of above-mentioned two kinds of processes, can realize the control of convection cell, satisfy clinical practice.
For convenient outlet valve joint and top medicated cap are carried out cleaning and sterilizing, the clamp-close type connection is adopted in connecting between outlet valve joint 9 and the shell 4; The top cap sleeve is contained in the front end of the axle of exhaling.During cleaning and sterilizing, can easily outlet valve joint and top medicated cap be taken off.
