The purpose of this utility model is that solve the above-mentioned problems and provides a kind of constant pressure air pressure valve.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes valve body, the first spool, the first spring, the first screw rod lid, the first screw rod, second spring,
The side of two spools, the second screw rod lid and the second screw rod, the valve body is provided with air inlet, and the other side of the valve body is provided with
Exhaust outlet, middle part one end and side of first spool are provided with the through-hole of perforation, the side through-hole position of first spool
At the air inlet, the end thereof contacts of the blind end of first spool and first spring, first spring it is another
One end is contacted with first screw rod, and first screw rod is threadedly coupled with the first screw rod lid, the first screw rod lid with
The valve body screw thread connection, the opening end in contact of one end of the second spring and first spool, the second spring
The end thereof contacts of the other end and second spool, the other end of second spool are contacted with second screw rod, and described
Two screw rods are threadedly coupled with the second screw rod lid, and the second screw rod lid is connect with the valve body screw thread, the exhaust outlet position
Between first spool and second spool.
The beneficial effects of the utility model are：
The utility model is a kind of constant pressure air pressure valve, compared with prior art, the utility model can constant air pressure, automatically
Control the open and close of gas supply, additionally it is possible to it is finely adjusted pressure, in addition, it is also equipped with the function of open and close, it is easy to control,
It runs, has the value of popularization and application conducive to equipment.
Description of the drawings
Fig. 1 is the schematic structural cross-sectional view of the utility model.
In figure：1- valve bodies, 2- air inlets, 3- exhaust outlets, the first spools of 4-, the first springs of 5-, the first screw rods of 6- lid, 7-
One screw rod, 8- second springs, the second spools of 9-, the second screw rods of 10- lid, the second screw rods of 11-.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes valve body 1, the first spool 4, the first spring 5, the first screw rod lid 6, the first spiral shell
Bar 7, second spring 8, the second spool 9, the second screw rod lid 10 and the second screw rod 11, the side of the valve body 1 are provided with air inlet
2, the other side of the valve body 1 is provided with exhaust outlet 3, and middle part one end and side of first spool 4 are provided with the logical of perforation
The side through-hole in hole, first spool 4 is located at the air inlet 2, the blind end of first spool 4 and first bullet
The end thereof contacts of spring 5, the other end of first spring 5 are contacted with first screw rod 6, first screw rod 6 and described the
One screw rod lid 6 is threadedly coupled, and the first screw rod lid 6 is threadedly coupled with the valve body 1, one end of the second spring 8 and institute
State the opening end in contact of the first spool 4, the end thereof contacts of the other end of the second spring 8 and second spool 9, described
The other end of two spools 9 is contacted with second screw rod 11, and second screw rod 11 is threadedly coupled with the second screw rod lid 10,
The second screw rod lid 10 is threadedly coupled with the valve body 1, and the exhaust outlet 3 is located at first spool 4 and second valve
Between core 9.
The operation principle of the utility model is as follows：
Air inlet 2 connects feeder, and device of air is held in the connection of exhaust outlet 3, and when holding the air pressure abundance of device of air, air pressure pushes away
Dynamic first spool 4 compresses the movement of the first spring 5, when dislocation between the opening and air inlet 2 of 4 side of the first spool until closing,
Reaching the function of constant pressure, the second spool 9 is adjusted by the second screw rod 11 and is moved, and the pressure of second spring 8 first can be adjusted, into
And the demand of constant pressure is finely tuned, the pressure of the first spring 5 is adjusted by the first screw rod 7 of adjusting, also the ginseng of adjustable settings constant pressure
Number adjusts the second screw rod 11 and moves at the second spool 9 to exhaust outlet 3, until closing exhaust outlet 3, plays the role of being opened and closed valve.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
