Working principle：When the discharge of the medium of diaphragm epicoele 16, the first sealing pair 9-12 of non-return valve core 9-6, which is in, to be closed
State；The second sealing pair 9-14 of adjusting spool 9-5 is in crack state, and adjusting its opening size can adjusting film piece epicoele 16
The water flow velocity of discharge, to control the opening speed of pipe power valve.Medium is flowed to referring to Fig. 6.When medium flows into diaphragm epicoele 16
When, non-return valve core 9-6 overcomes spring force to move down under water jet propulsion, and adjusting spool 9-5 is also moved down therewith, the first sealing
Secondary 9-12 is opened, and medium flows into diaphragm epicoele 16, and the small flap 3 of pipe power valve is closed；Adjustment spring gland 9-8 controls spring 9-7's
Elastic force enables the first sealing pair 9-12 slightly to close both may be used.Medium is flowed to referring to Fig. 7.
When the discharge of the medium of diaphragm cavity of resorption 19, the first sealing pair 9-12 of non-return valve core 9-6 is in close state；It adjusts
The second sealing pair 9-14 of spool 9-5 is in crack state, and the water flow row of diaphragm cavity of resorption 19 can be adjusted by adjusting its opening size
Speed out, to control the closing velocity of the small flap 3 of pipe power valve.Medium is flowed to referring to Fig. 6.When medium flows into diaphragm cavity of resorption 19
When, non-return valve core 9-6 overcomes spring force to move down under water jet propulsion, and adjusting spool 9-3 is also moved down therewith, the first sealing
Secondary 9-12 is opened, and medium flows into diaphragm cavity of resorption 19, and pipe power valve is slowly opened.The elastic force of adjustment spring gland 9-8 control spring 9-7
Size can control the cracking pressure of the first sealing pair 9-12；When this pressure is set as water pump rated head, sky can be realized
Carry the function of opening pump；Medium is flowed to referring to Fig. 7.
Valve opening：After water pump starting, pipe power valve import end pressure P1（Referring to Fig. 1）It gradually rises, eccentric big valve flap 2 is in water flow
It under promotion, is intended to around valve rod 27 rotationally clockwise, but small flap 3 is under 16 pressure medium P2 of diaphragm epicoele effect at this time, pressure
Firmly eccentric big valve flap 2, prevents its rotation, valve can not be opened；When input end pressure medium P1 is more than downstream pressure P2, into
Mouth end pressure water wherein all the way, through 20 inlet membrane cavity of resorption 19 of import bypass pipe, pushes 12 uplink of diaphragm, is driven by mandril 7
Small flap 3 rotationally clockwise, releases the constraint to eccentric big valve flap 2.The another way of import end pressure water pushes eccentric big
Flap 2 rotates, and follows small flap 3 closely and slowly opens together, completes valve opening.Meanwhile in diaphragm epicoele 16 medium through export bypass pipe
21 flow back to pipe power valve outlet end, referring to Fig. 3.
Close valve：When termination of pumping or forced outage, pipe power valve import end pressure P1 is quickly reduced, when water velocity is close to " 0 ",
For eccentric big valve flap 2 under the effect of self gravity square, most reflux medium is truncated in quick closedown（Referring to fig. 4）；At this point, going out
Mouth pressure P2 is far longer than inlet pressure P1, and outlet end medium rapidly enters diaphragm epicoele 16 through exporting bypass pipe 21, pushes film
12 downlink of piece drives small 3 slowly closing of flap by mandril 7；Final pipe power valve completely closes（Referring to Fig. 1）.Meanwhile under diaphragm
The medium of chamber 19 flows back to pipe power valve input end through import bypass pipe 20.During small 3 slowly closing of flap, discharge orifice 22 is let out
Except a small amount of recirculation water, to cut down water hammer pressure peak value.According to water hammer time of return, when the closing of the small flap 3 of Field adjustment
Between, it is ensured that water hammer surge pressure prevents water hammer accident no more than 1.2 times of design engineering pressure, it is ensured that pipe network equipment peace
Entirely.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that：It still may be used
To modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features；And
These are modified or replaceed, the spirit and model of technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
