The connection of strut 22, and plain washer 20 is additionally provided between wing nut 21 and pipe clamp 18, in practical applications, butterfly valve can be passed through
The being completely embedded property of pipe clamp 18 and supporting rod 22 is adjusted, and plain washer 20 also avoid the rigidity between wing nut 21 and pipe clamp 18
Contact.
It is further preferred that boring cover 7 and threeway water exit elbow 9 use thread fitting, and inner sealing pad 8 compress it is close
Envelope, threeway water exit elbow 9 and valve body 13 are coordinated using fine thread sealing, and 13 other end of valve body and water inlet elbow 14 use fine thread
Sealing coordinates.Water inlet elbow 14 and water inlet gland 17 use thread fitting, and inlet strainer 16 is clamped.15 insertion valve body of pearl gear
13.Piston ring 10 and connector 5 coordinate, and connector 5 coordinates with 3 fine thread of piston rod, and boring cover 7 is used with threeway handle base 2
Fine thread sealing coordinates.
In practical applications, when single foot slam the supporting rod 22 of fixed frame it is foot-operated when, during with having pulled spanner, such as Fig. 4
It is shown, shot 4 in piston rod 3 because centrifugal force reason does not leave original position always, and the space of the second sub-chamber 27 with
The rising of the sealing position of piston ring 10 is reduced at leisure, and at the same time, the shot 4 of entrance leaves original position because of pressure vacuum,
So as to which water enters the first sub-chamber by water inlet gland 17, inlet strainer 16, the shot 4 of water inlet elbow 14, entrance, pearl gear 15
26 inside.
When handle 1 down on time, as shown in figure 5, the space of the second sub-chamber 27 is with the sealing position of piston ring 10
Slowing down slowly increases, and the steel ball 4 of entrance also recovers origin-location because of centrifugal force reason causes inlet seal, same with this
When, cause the water in the first sub-chamber 26 to be extruded the shot 4 so that in piston rod 3 because the sealing position of piston ring 10 declines
Original position have left by hydraulic pressure, so that water is by piston ring 10,11, two thin nuts 12 of pressure pad, the shot 4 in piston rod 3, piston
The first end 31 of bar 3, then in the second sub-chamber 27, but the shot 4 in the piston rod 3 of stress has blocked the big face of piston rod 3
Long-pending depths passage, then extrude stress hydraulic pressure disperseed, it is on the wall of the first end 31 of piston rod 3 and with the second sub-chamber
The places of the communicating outflow of 27 connections, and entrance second is improved oneself interior, so as to flow out outlet.
Action is returned into Fig. 4 again, because the sealing position of piston ring 10 rises, the space of the first sub-chamber 26 is reduced, not
The water of outflow is flowed out by the 3rd mouth of pipe 93 of threeway water exit elbow 9, is also come in stylish water from import.
Then Fig. 5 actions are repeated, new water promotes old water sport outflow outlet.
Next Fig. 4 and Fig. 5 movements are iteratively repeated, so so that a reciprocating motion of piston rod 3, realizes water
Continuous conveying, and speed is faster, outlet hydraulic pressure is higher, and flow velocity is also faster.
It is following (but not unique) for the assemble method of this example：The first step：Shot 4 is arranged on the of piston rod 3
At one end 31, and 11, two connector 5, piston ring 10, pressure pad thin nuts 12 are attached successively；Second step：By piston rod
3 first end 31 runs through the pump chamber of valve body 13 so that the tip protrusion of second end 32 causes piston in the water outlet of valve body 13
The outer wall of the first end 31 of bar 3 is engaged with the inner wall sealing of valve body 13；3rd step：Shot 4 is placed on to the loudspeaker of water inlet elbow 14
At shape junction structure, and the water inlet end by water inlet elbow 14 installed in valve body 13；Threeway water exit elbow 9 is installed on valve body 13
At water outlet, and the gasket 8, boring cover 7, rubber pad 6 of trapezium structure are installed on to second mouth of pipe of threeway water exit elbow 9 successively
At 92；4th step：Handle 1 is installed on threeway handle base 2, and threeway handle base 2 is installed on to the second end of piston rod 3
32；5th step：By inlet strainer 16 by intaking gland 17 in water inlet elbow 14；6th step：Supporting rod 22 is passed through
Fixed frame is installed on valve body 13.At this time, the water pumping valve side of the utility model is completed, and can be come into operation.Certainly, if
During use, when some component of this water pumping valve is damaged and needs replacing, and dismantled, and change new component
.
In the utility model, the water inlet height of water pumping valve is determined by the foot-operated of supporting rod 22 with water inlet elbow 14, works as support
When the foot-operated supporting surface of bar 22 is flushed with the bottom surface of water inlet elbow 14, water inlet height at this time is high by the tube wall of water inlet elbow 14
Degree decision, and since fixed seat and valve body 13 are detachable connections, user can adjust this pumping according to being actually needed
The water inlet height of water valve, does not just repeat one by one here.
It should be noted that above-described embodiment can be freely combined as needed.The above is only the utility model
Preferred embodiment, it is noted that for those skilled in the art, do not departing from the utility model principle
On the premise of, some improvements and modifications can also be made, these improvements and modifications also should be regarded as the scope of protection of the utility model.
