Description
Technical field
This utility model relates to the fast arranging device of a kind of pneumatic operated valve driving gas for pneumatic operated valve, particularly relates to the fast arranging device of a kind of pneumatic operated valve driving gas for medical breathing machine pneumatic operated valve.
Background technology
There is following problem in the like product of Use of respirator at present:
1, the discharge of pneumatic operated valve driving gas relies on pilot valve air vent to discharge, and because pilot valve air vent needs noise reduction process, makes the driving gas cannot quick drain, causes respirator inspiratory duration accurately to control;
2, respirator carries out mechanical ventilation by gas output, and it is objective reality that the fluctuation range of different ventilation build-ups of pressure changes, thereby cause pilot valve driving gas mass rate of emission to change.
Summary of the invention
The purpose of this utility model is just for above-mentioned like product existing problem and shortage part and a kind of fast arranging device of pneumatic operated valve driving gas for medical breathing machine pneumatic operated valve is provided in use.This device is arranged between pilot valve and pneumatic operated valve driving gas input port, has fundamentally solved existing weak point in prior art.
The purpose of this utility model realizes by following version:
The fast arranging device of pneumatic operated valve driving gas of the present utility model comprises the bottom that is provided with center gas input hole that is arranged on the fast row's core that is provided with center gas delivery outlet in fast isostere valve pocket in coaxial line mode by screw thread and is arranged on fast isostere valve pocket bottom, and be arranged on the diaphragm between fast row's core and bottom, diaphragm is installed in the annular groove processing in fast isostere inner chamber, by bottom press seal; The centre of described diaphragm is provided with the concentric pylone that is communicated with fast row's core center gas delivery outlet and bottom center gas input hole; Described fast row's core and diaphragm abutting end are male-tapered structure; Side steam vent with fast isostere intracavity inter-connection is set in fast isostere.
Operation principle of the present utility model is as follows:
The pneumatic operated valve driving gas of pilot valve output enters fast arranging device by bottom gas input connectivity port, the driving gas diaphragm concentric pylone of flowing through, because diaphragm cross-sectional area is far longer than its concentric pylone, the pressure that driving gas produces diaphragm is greater than it to centre bore opposition, fast-discharge valve forms closed cavity, and driving gas is exported to pneumatic operated valve driving gas input port by the gas output end mouth of arranging soon core.
Pilot valve is closed without driving gas output, and because pilot valve air vent discharges driving gas, diaphragm two ends mineralization pressure is poor, and diaphragm is subjected to displacement, and pneumatic operated valve driving gas is by the steam vent quick drain of fast isostere.
The beneficial effects of the utility model are as follows:
, fundamentally solved driving gas and discharged uncontrollable state;
B, pneumatic operated valve cuts out phenomenon not in time while effectively having overcome driving gas pressure oscillation;
C, effectively overcome driving gas circuit and relied on pilot valve aerofluxus, become passive aerofluxus into initiative exhaust.
Accompanying drawing explanation
Fig. 1 is the profile of utility model.
In figure: (1) arranges core soon, (2) fast isostere, (3) steam vent, (4) diaphragm, (5) bottom, (6) center gas input hole, (7) concentric pylone, (8) male-tapered structure, (9) center gas delivery outlet.
The specific embodiment
This utility model is further described below in conjunction with (accompanying drawing):
As shown in Figure 1, the fast arranging device of pneumatic operated valve driving gas of the present utility model comprises the bottom that is provided with center gas input hole (6) (5) that is arranged on the fast row's core (1) that is provided with center gas delivery outlet (9) in fast isostere (2) valve pocket in coaxial line mode by screw thread and is arranged on fast isostere (2) valve pocket bottom, and be arranged on the diaphragm (4) between fast row's core (1) and bottom (5), diaphragm (4) is installed in the annular groove processing in fast isostere (2) inner chamber, by bottom (5) press seal; The centre of described diaphragm (4) is provided with the concentric pylone (7) that is communicated with fast row's core (1) center gas delivery outlet (9) and bottom (5) center gas input hole (6); Described fast row's core (1) is male-tapered structure (8) with diaphragm (4) abutting end; The side steam vent (3) of the upper setting of fast isostere (2) and fast isostere (2) intracavity inter-connection.
Specific works mode of the present utility model is as follows:
Valve driving gas enters fast arranging device by the center gas input hole (6) of bottom (5), driving gas diaphragm (4) concentric pylone (7) of flowing through, because diaphragm (4) cross-sectional area is far longer than its concentric pylone (7), the pressure that driving gas produces diaphragm (4) is greater than it to concentric pylone (7) opposition, fast-discharge valve inner chamber forms closed cavity, and driving gas is exported to pneumatic operated valve driving gas input port by the center gas delivery outlet (9) of arranging soon core (1).
Pilot valve is closed without driving gas output, and because pilot valve air vent discharges driving gas, diaphragm (4) two ends mineralization pressure is poor, and diaphragm (4) is subjected to displacement, and pneumatic operated valve driving gas is by steam vent (3) quick drain of fast isostere (2).
Claims (1)
