Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row is elaborated.
First embodiment：
As shown in Figure 1 to Figure 3, the utility model discloses a kind of water hammer-resistant pressure-reducing valve, and it includes lid 1, matched somebody with somebody with upper lid 1
The bottom 2 of conjunction, the adjustment sheet 3 in upper lid 1 and bottom 2 and regulation spring 4；Wherein described adjustment sheet 3 passes through a Guiding machine
Structure displacement between upper lid 1 and bottom 2；
Specifically, the upper lid 1 includes a cavity volume 10, the top of cavity volume 10 is a gear provided with water inlet along 12, side
Portion is the side wall 11 of an annular, and bottom and the screw thread of bottom 2 of the side wall 11 coordinate.
Coordinate Fig. 1, the adjustment sheet 3 is the funnel-shaped structure that diameter is inwardly tapered from top to bottom, and middle part is formed with a mistake
Water hole 31；The external profile diameter of adjustment sheet 3 is less than the internal diameter of the side wall 11 of upper lid 1 so that have one between adjustment sheet 3 and side wall 11
Fixed gap constitutes auxiliary flow 5；The adjustment sheet 3 is outwards also extended with least two protuberances 32 to stable regulation piece 3, institute
The external diameter for stating the composition of protuberance 32 is identical with the internal diameter of side wall 11.
The periphery of the bottom 2 is formed with an annular perisporium 21, and side wall 11 of the perisporium 21 provided with screw thread and upper lid 1 is matched somebody with somebody
Close；The bumping post 22 of the water hole 31 of a socket adjustment sheet 3 is upwardly formed in the middle of the bottom of the bottom 2, the bumping post 22 prolongs upwards
Stretching has oblique retaining surface 23, and the oblique retaining surface 23 is bottom-up tapered, and the diameter of the bumping post 22 of the bottom of oblique retaining surface 23 is more than or waited
In the diameter phase of water hole 31；Several delivery ports 24 are formed between perisporium 21 and bumping post 22, are set between each delivery port 24
There is the connection rib 25 of connection perisporium 21 and bumping post 22；.
The guiding mechanism is the guiding rib 26 that oblique retaining surface 23 is upwardly extended, and the guiding rib 26 is at least two,
Preferably three simultaneously central shaft distributions of the uniform ring around bumping post 22.
When the utility model is assembled, regulation spring 4 described first is first nested with bumping post 22 and lower end is connected on rib；
Then the adjustment sheet 3 be nested with again be oriented to rib 26 on and against regulation spring 4 upper end；Finally upper lid 1 is by the He of adjustment sheet 3
The regulation cover of spring 4 is placed in cavity volume 10, and upper lid side wall 11 coordinates with the screw thread of bottom 2.
The utility model can be implemented on the joint of pipeline, when it is implemented, water inlet of the current of pipeline from upper lid 1
13 flow into, and coordinate Fig. 4, when the hydraulic pressure of pipeline is relatively low, i.e. state one, and hydraulic pressure can not overcome regulation to the power that adjustment sheet 3 applies
The elastic force of spring 4, adjustment sheet 3 is in the top state, against the gear of upper lid 1 along 12, and current are from auxiliary flow 5 and water hole 31
Cross after water and to be flowed out from delivery port 24, the energy loss influence on current is small.
Coordinate Fig. 5, when the hydraulic pressure of pipeline gradually increases, i.e. state two, hydraulic pressure gradually overcomes tune to the power that adjustment sheet 3 applies
The elastic force of spring 4 is saved, the energy of water impact is partially converted to adjust the elastic potential energy of spring 4, makes adjustment sheet 3 by Guiding machine
Structure is moved to lower end, and current cross water from the auxiliary flow 5 and water hole 31 in outside, but the water hole 31 of adjustment sheet 3 is tiltedly kept off
The effect in face 23, its discharge area is gradually reduced, and makes part water impact oblique retaining surface 23 and reverse flow, offsets water inlet
Part flow energy, the influence of the energy losses of current is gradually increased, water flow impact pressure reduction so that the flow of delivery port 24
Keep stable with flow velocity.
Coordinate Fig. 6, when hydraulic pressure exceedes setting pressure, i.e. state three overcomes regulation spring 4 to the power that adjustment sheet 3 applies
Elastic force, the energy of more water impacts is converted to the elastic potential energy of regulation spring 4 so that adjustment sheet 3 continues to push, water hole
31 are blocked by bumping post 22, and current cross water from the auxiliary flow 5 of side, and overall discharge area is small, and middle current all can quilt
Oblique retaining surface 23 reflects and mutually impacted with the current of water inlet 13, offsets a big chunk flow energy of water inlet 13 so that
The impulsive force of current is substantially reduced, so as to ensure that the flow and flow velocity of delivery port 24 keep stable.
Further, the perisporium 21 is located in upper lid, i.e., the formation of perisporium 21 external screw thread coordinates with side wall 11, such as Fig. 7 and Fig. 8
It is shown, after hydraulic pressure exceedes setting pressure, continue to increase again, adjustment sheet 3 continues to move down, auxiliary flow 5 progressively close to perisporium 21,
So that the discharge area of auxiliary flow 5 reduces, until adjustment sheet 3 is resisted against on bottom, now overall discharge area is minimum, but
Overall discharge area is not zero, further the flow and flow velocity of control current, it is ensured that the whole flow of delivery port 24 and flow velocity are protected
Hold a stable state.
Further, the height of perisporium 21 can also be adjusted, coordinates Fig. 9, after hydraulic pressure exceedes maximum set pressure, adjustment sheet
3 move down so that water hole 31 is blocked by bumping post 22 and auxiliary flow 5 is blocked completely by perisporium 21, form a nearly sealing shape
State so that delivery port 24 flows out without current.
Further, the gear of the adjustment sheet 3 and upper lid 1 is also provided with anticollision spring along between 12, it is to avoid water inlet 13
Hydraulic pressure drop suddenly suddenly, regulation spring 4 resets, and causes adjustment sheet 3 directly to hit gear along 12.
