Abstract
The invention relates to an electronic flow valve for controlling oxygen conveyance. The electronic flow valve is mainly composed of a direct current motor (1), a valve core (3), a seal ring (4) and a valve body (5). The electronic flow valve is characterized in that the direct current motor (1) drives the valve core (3) to rotate and perform displacement in an air inlet channel (6) in the valve body (5), the gap distance between the valve core (3) and an inner wall of the air inlet channel (6) in the valve body (5) is changed through the rotation and displacement, and accordingly the control goal of controlling oxygen starting, adjusting flow or shutting down oxygen is achieved. The electronic flow valve has the advantages that the electronic flow valve is low in technical implementation difficulty and manufacturing cost, small in size and high in flow control accuracy; and the electronic flow valve produced according to the technical scheme can be widely applied to various electronically controlled oxygen inhalator products.
Description
Art
The present invention relates to a kind of electronic flow valve controlling oxygen infusion, belong to the flow control component in the oxygen inhalation apparatus of medical institutions' use.
Background technique
Oxygen uptake is the most frequently used one of the rescue or treatment means of hospital, and oxygen inhalation apparatus (being commonly called as flowmeter) regulates and observe the indispensable utensil of oxygen flow in oxygen uptake process.Current domestic hospitals generally adopts float flowmeter, and the defect of this series products is that Flow-rate adjustment is inconvenient, error in dipping is large, reading is inconvenient, data cannot store.In recent years, the domestic technological scheme also proposing some employing electronic valves control oxygen flows, as CN 103386159 A, CN 104587576 A etc. all propose to adopt electronic flow control valve adjustment flow, but do not further illustrate structure and the working principle of electronic flow control valve.Due in oxygen inhalation apparatus product, flow control valve required precision high (national sector standard YY1107-2003 requires that flow error is no more than 4%), and the electronic flow control valve volume gone on the market at present is large, price is high, control accuracy is low, and customize the satisfactory electronic flow control valve price of precision costly, cannot meet oxygen inhalation apparatus needs of production, therefore many technological schemes cannot be implemented in actual production.
For this reason, the present invention is proposing a kind of electronic flow valve brand new technical scheme controlling oxygen infusion, and small product size is little, precision is high, cost is low, is conducive to promoting the popularization use.
Summary of the invention
The present invention proposes a kind of electronic flow valve controlling oxygen infusion, primarily of direct current generator, driving component, spool, seal ring, valve body, gas-entered passageway composition, wherein:
Be provided with driving component between described direct current generator and spool, direct current function directly or indirectly drives valve core rotation and straight-line displacement;
Described driving component includes but not limited to any one or a few combination of gear, tooth bar, belt pulley, bent axle, connecting rod, belt, chain, wheel shaft, axle etc.;
The seal periphery of described spool is provided with seal ring;
Gas-entered passageway, oxygen delivery outlet is provided with in described valve body;
One end that described gas-entered passageway is positioned at valve inner can coincide with the seal of spool is airtight, and gas-entered passageway is positioned at valve body lateral ends and can be communicated with the connected element of oxygen source is airtight;
Described electronic flow valve and the kernel control module UNICOM of oxygen inhalation apparatus work, and accept unlatching that kernel control module provides, closedown or flow adjustment instruction and action; Described kernel control module includes but not limited to single-chip microcomputer, flow measurement module, surface-mounted integrated circuit.
A kind of electronic flow valve controlling oxygen infusion, its major character is: direct current generator drives spool displacement in valve inner gas-entered passageway by driving component, change the seal of spool and the clearance distance of valve inner gas-entered passageway inwall by displacement, thus reach the control objectives controlling oxygen unlatching, uninterrupted adjustment or close.
At least should have 0.5mm adjustable clearance distance between the seal of spool and valve inner gas-entered passageway inwall, when spool is by DC motor Driver displacement, the seal of spool and the clearance distance of valve inner gas-entered passageway inwall can regulate between 0 ~ 100%; When described clearance distance is 0, seal and the valve inner gas-entered passageway inwall of spool fit like a glove, seamless, oxygen output passage is blocked completely, oxygen export be in closed condition; When described clearance distance is 100%, valve inner gas-entered passageway is completely open, oxygen exports and is in full load condition (namely reaching the maximum value appraising and deciding output); When the maximum value supposing to appraise and decide output is 10L/min, the clearance distance of the seal of spool and valve inner gas-entered passageway inwall regulates between 0 ~ 100%, the corresponding Oxygen Flow value exported also is regulated between 0 ~ 10L/min.
The adjustment of the seal of spool and the clearance distance of valve inner gas-entered passageway inwall is that the instruction sent by kernel control module realizes, kernel control module sends " closedown " or the instruction of " stopping " similar function time, the displacement in valve inner gas-entered passageway of DC motor Driver spool, displacement mode can be that spool is pushed ahead, until the clearance distance of the seal of spool and valve inner gas-entered passageway inwall is 0, oxygen output passage is blocked completely, and oxygen exports closes; When kernel control module sends open command or provides corresponding flow value, the displacement in valve inner gas-entered passageway of DC motor Driver spool, displacement mode can be that spool is shunk back backward, the seal of spool and the clearance distance of valve inner gas-entered passageway inwall regulate arbitrarily between 0 ~ 100%, the change of the flow measurement module synchronization trace flow value in kernel control module, when the Oxygen Flow value exported is consistent with the flow value that kernel control module provides, direct current generator is by spool travel locking position.
The periphery of described spool can also be provided with supporting valve core rotation and the spool guide rail of straight-line displacement, and the Main Function of spool guide rail is the seal skew making spool keep stablizing, reducing spool in displacement process.The set-up mode of spool guide rail is not limit, and can be cylinder, circle, screw rod, nut etc.; Be the most easily adopt that hard wear-resistant material is made, can inclusion guide the cylinder of spool travel, spool is positioned in the middle of cylinder; Preferred version arranges thread groove (being equivalent to nut) as the cylinder inner wall of spool guide rail, spool periphery also arranges the screw thread that can coincide mutually with thread groove in cylindrical body, during valve core rotation, spool advances with screw rod rotation mode, makes Spool rotating displacement more stable.
Advantage of the present invention is: technology enforcement difficulty is low, low cost of manufacture, volume are little, flow control accuracy is high, and the electronic flow valve adopting the technical program to implement to produce can be widely used in various electronically controlled oxygen inhalation apparatus product.
