Accompanying drawing explanation
With detailed description of the invention this utility model made further details of theory below in conjunction with the accompanying drawings
Bright.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A in Fig. 1.
Detailed description of the invention
A kind of medical gas supply termination with filtering function as shown in Figure 1, including valve seat
2, gland 1, base 7, pneumatic filter 10, spool 4, air inlet pipe 8 and air pressure protection dress
Putting, described gland 1 is arranged on valve seat 2, the lower end phase of described base 7 and valve seat 2
Even, in described base 7, offer base gas outlet, described base 7 is further opened with
The air inlet 9 of base gas outlet connection, described pneumatic filter 10 is arranged on air inlet 9
In, described spool 4 is arranged on the lower section of valve seat 2, the bottom of described spool 4 and base
Being provided with spring 6 between 7, described air inlet pipe 8 is connected with air inlet 9 by water conservancy diversion storehouse 11
Logical, the sidewall in described water conservancy diversion storehouse 11 offered pressure passageway 16, described air pressure protection
Device was arranged at pressure passageway 16, was provided with rubber close between described valve seat 2 and base 7
Seal 3.When air feed terminal set internal gas pressure is excessive, air pressure protection device 14 then can be voluntarily
Start and reduce pressure differential, thus serve the effect of self-protection, prevent due to excessive pressure
And cause the generation that self structure damages；And it also has simple in construction, easily fabricated and real
Use efficient advantage.
Air pressure protection device as shown in Figure 2 include valve head 15, guide post, adjustable plate 14,
Regulation spring 17 and regulation bolt 18, the roof in described water conservancy diversion storehouse 11 also sets up rail
Road 12, one end of described adjustable plate 14 is flexibly connected on the track 12 by slide block 13,
Described valve head 15 was arranged on the outside of pressure passageway 16, and one end of described guide post passes
Adjustable plate 14, the other end of described guide post passed pressure passageway 16 and was connected with valve head 15,
Described regulation spring 17 is looped around the outside of guide post, one end of described regulation spring 17
Being connected with adjustable plate 14, the other end of described regulation spring 17 connects on the guide bar, institute
The valve head 15 stated is sealed crossing pressure passageway 16 by regulation spring 17, described water conservancy diversion
Being further opened with screwed hole on the sidewall in storehouse 11, described regulation bolt 18 is through screwed hole and tune
Joint plate 14 is connected.According to demand by rotating regulation bolt 18 regulation regulation spring before work
The pretightning force of 17, when air pressure is excessive, high pressure gas knows from experience promotion valve head 15 stretching regulation spring
17, now to cross pressure passageway 16 and no longer seal, gases at high pressure then can be run out of from crossing pressure passageway 16,
Thus it is poor to reduce external and internal pressure, when, after stable gas pressure, regulation spring 17 then can move valve head 15 to
Again pressure passageway 16 was blocked；This utility model is protected by being arranged on the air pressure at pressure passageway
Protection unit plays the effect of self-protection, prevents from causing self structure due to excessive pressure
The generation damaged.
