Description
Technical field
The utility model relates to oxygenerator parts, is specifically related to a kind of oxygenerator flow control device.
Background technique
When use does not adopt the oxygenerator of flowmeter, the different time, generally need to export different flows, to meet the oxygen uptake demand under different situations.At present the metering holes of several different flows that adopt are controlled more, and traditional metering hole processes the aperture of a certain diameter on solid material, by orifice restriction, reaches the object of controlling flow.If during batch production, the hole diameter of same specification limit discharge orifice often exists deviation, also can there is deviation in the output flow conformity of so same specification limit discharge orifice.As need are eliminated this deviation, can only be ceaselessly method by secondary operations (for example ream, press from both sides flat etc.), change metering hole circulation area, with flowmeter, detect output flow simultaneously, until the flow of output meets the requirements, during final assurance batch production, the conformity of same specification limit discharge orifice output flow.This process operation is complicated, and manufacturing efficiency is low, and cost of production is high, is not well positioned to meet industrial production in enormous quantities.
Model utility content
The technical problem that the utility model solves is to provide a kind of oxygenerator flow control device, thereby solves the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
An oxygenerator flow control device, this device is installed on oxygenerator, between compressor outlet and oxygen output tube.This device is by housing, valve core rod and seal ring form, form one or several regulon, in described housing, there is an airflow line, on described airflow line, be provided with at least three air outlets vertical with described airflow line, described housing offers the mounting hole with described air outlet coaxial line, described valve core rod is installed in described mounting hole, the upper end portion of described valve core rod utilizes thread engagement to be installed in described mounting hole, described seal ring is housed on described valve core rod, keep airtight with described mounting hole, the underpart of described valve core rod is one section of conical surface core bar, described conical surface core bar stretches in described air outlet, the conical surface of described conical surface core bar and the inner cylindrical surface of described air outlet form an annular cross section, gas flow is crossed described annular cross section, by described annular cross section, play throttling action, with flowmeter, detect output flow simultaneously, until the flow of output meets the requirements, the conformity of the regulon output flow of same requirement on each flow control device during final assurance batch production.And by different regulons, realize different flows and export.
Working principle of the present utility model is that each regulon can pass through rotary valve core bar, make the conical surface at valve core rod top stretch into inside, air outlet, form and coordinate with air outlet endoporus, make the valve core rod conical surface on positions different, that applicable each regulon requires, thereby realize each regulon, export different flows.If during batch production, when on flow control device there is conformity deviation in the output flow of the regulon of same requirement, can pass through rotary valve core bar, change valve core rod in the position of the housing endoporus depth, thereby change the circulation area between valve core rod and housing endoporus, with flowmeter, detect output flow simultaneously, until the flow of output meets the requirements, the final conformity of the regulon output flow of same requirement on each flow control device while guaranteeing batch production.This device can provide one or more different output flows that require, and easy and simple to handle in process of production, manufacturing efficiency is high, the same flow high conformity that requires regulon, and cost of production is low, is well positioned to meet industrial production in enormous quantities.
When the utility model is used in batch production, utilize screw thread can regulate the degree of depth that coordinates of conical surface core bar and air outlet, change circulation area, with flowmeter, detect output flow simultaneously, until the flow of output meets the requirements, the final conformity of the regulon output flow of same requirement on each flow control device while guaranteeing batch production.And by different regulons, realize different flows and export.
Owing to having adopted above technological scheme, the utility model has following beneficial effect when batch production:
The utility model is simple in structure, easy to use, and manufacturing efficiency is high, the flow high conformity of same regulon, and cost of production is low, and the different output flows that require can be provided, and is well positioned to meet industrial production in enormous quantities.
