The utility model discloses can realize traditional anesthesia machine venturi valve's function, increase venturi valve's adjustable function moreover, promote venturi valve's adaptability.
Description
Technical field
This utility model belongs to gas piping design field, is specifically related to a kind of adjustable venturi valve.
Background technology
Tradition anesthetic machine, when use venturi principle gives vent to anger interface, mainly allows high velocity air converge with low speed flow,
And reduce produce based on Venturi effect on low speed flow channel pressure affect, it is ensured that the pressure of air-channel system is steady
Fixed.
Traditional venturi valve is all fixing uncontrollable, and its single structures shape is at different operating environment
Under the limitation that has, under special circumstances, gas circuit is unstable, and directly impacts the pressure of air-flow.
Utility model content
Fixing for venturi valve structure of the prior art, have limitation under different operating environment, this practicality is new
Type provides a kind of new adjustable venturi valve, and this venturi valve adds relative to traditional venturi valve can
The function of regulation, improves the adaptability of valve.
The venturi valve that this utility model provides includes that valve body and slidable adjustment bar, the number of described slidable adjustment bar are 1
Or 2 set；The front portion of described slidable adjustment bar is boss-shaped structure, and the rear portion of described slidable adjustment bar is provided with gas
Interface, described gas interface is connected with gas access, is provided with gas passage, described cunning in the middle part of described slidable adjustment bar
The front portion of dynamic adjusting rod is stretched in the gas channels in valve body；The internal diameter of the gas passage arranged in the middle part of described adjusting rod
Less than the internal diameter of gas channels in the valve body that described slidable adjustment bar stretches into.
Preferably, described valve body is cylindricality, the height being passed through after described low velocity gas enters valve body and in described gas passage
Speed gas mixing.
Preferably, described valve body, adjusting rod and gas interface are integral type structure.
This utility model can realize the function of traditional anesthetic machine venturi valve, and add venturi valve can
Regulatory function, improves the adaptability of venturi valve.
Accompanying drawing explanation
Fig. 1, the sectional view of adjustable venturi valve of the present utility model.
The sectional view of the venturi valve after Fig. 2, mobile adjusting rod.
Accompanying drawing identifies:
1, the first gas feed；2, valve body；3, slidable adjustment bar；4, the second gas feed.
Detailed description of the invention
To illustrate utility model in conjunction with accompanying drawing as follows, it only illustrates rather than restriction with to of the present utility model.
Fig. 1 and Fig. 2 illustrate a kind of actually used in adjustable venturi valve inside structure when different conditions
Make, that includes the first gas feed 1 and the second gas feed 4, can be seen that low speed gas by the sectional view of Fig. 1
The air inlet position of body is to maintain constant on valve body, and the position, gas outlet of high-speed gas is to maintain on adjusting rod
Constant, it is the structure that can regulate relative position between regulating valve stem and valve body.
The position that in Fig. 1 and Fig. 2, regulating valve stem is different on valve body is fixed, and can cause the air inlet of low velocity gas
Mouth changes relative to position with the import of high-speed gas, according to Venturi effect, it may be determined that be in difference at the two
Relative position time, when high-speed gas passes through, to low velocity gas entrance produce pressure influence have significant change.
Concrete, venturi valve includes that valve body 2 and slidable adjustment bar 3, the number of described slidable adjustment bar 3 are 1
Set, another gas circuit entrance then selects conventional access way；The front portion of described slidable adjustment bar 3 is boss-shaped structure,
The rear portion of described slidable adjustment bar 3 is provided with gas interface, described gas interface and gas feed, and (the second gas enters
Mouth 4) connect, it is provided with gas passage in the middle part of described slidable adjustment bar 3, the front portion of described slidable adjustment bar 3 is stretched
Enter in the gas channels in valve body；The internal diameter of the gas passage arranged in the middle part of described slidable adjustment bar 3 is less than described cunning
The internal diameter of gas channels in the valve body 2 that dynamic adjusting rod 3 stretches into；First gas feed 1 then connects another gas circuit.High
Speed gas and low velocity gas can changing-over as required, the second gas feed 3 herein is connected with high-speed gas entrance,
The most above-mentioned slidable adjustment bar 3 is it can also be provided that 2, and corresponding two gas circuits are the most directly connected into and are slidably connected
In the air-path interface of bar.
Claims (3)
1. an adjustable venturi valve, it is characterised in that described venturi valve includes that valve body and slidable adjustment bar, the number of described slidable adjustment bar are 1 or 2 sets；The front portion of described slidable adjustment bar is boss-shaped structure, the rear portion of described slidable adjustment bar is provided with gas interface, described gas interface is connected with gas access, is provided with gas passage in the middle part of described slidable adjustment bar, and the front portion of described slidable adjustment bar is stretched in the gas channels in valve body；The internal diameter of gas channels in the internal diameter of the gas passage of setting is less than the valve body that described slidable adjustment bar stretches in the middle part of described adjusting rod.
Venturi valve the most according to claim 1, it is characterised in that described valve body is cylindricality, the high-speed gas mixing being passed through after low velocity gas enters valve body and in described gas passage.
3. according to claim 1 or described venturi valve, it is characterised in that described valve body, slidable adjustment bar and gas interface are integral type structure.
