Detailed description of the invention
Embodiment 1
As shown in Figure 1: non-return hydraulic regulating valve, including valve body 10, there is in the middle part of this valve body 10 valve pocket 13, and this valve body 10
Left part is provided with horizontal-extending water inlet 11, right part has the most horizontal-extending outlet 12, this water inlet 11 and outlet
12 are connected by the face passage 133 that dams, and this face passage 133 that dams is positioned at the lower openings of this valve pocket 13.That is, this dams
Opening or closing of face passage 133, forms connecting or blocking of this water inlet 11 and this outlet 12, it is achieved that this non-return liquid
The switch of pressure regulation valve.
It is provided with in this valve pocket 13 and can move up and down and this valve pocket 13 is divided into upper cavity 131 and the work of lower chamber 132
Plug 20.Certainly, this piston 20 is necessarily arranged with and sealing ring that the sidewall of this valve pocket 13 matches.This piston 20 bottom is provided with
The valve plate 21 matched with this face passage 133 that dams, and this piston 20 is furnished with the stage clip 22 made it have to bottom offset trend.That is,
After this piston 20 moves up and down, drive this valve plate 21 to move up and down, this face passage 133 that dams is opened or closed.
The sidewall of this valve body 10 is provided with pressurization passageway 14 and pressure release passage 15, and this pressurization passageway 14 connects this water inlet 11
With this upper cavity 131.That is, the water in this water inlet 11 can enter in this pressurization passageway 14.
This upper cavity 131 is internal is provided with the fixed plate 31 and swivel plate 32 being pressed on together, this fixed plate 31 is above,
This swivel plate 32 is positioned at lower section.That is, the upper surface of the lower surface of this fixed plate 31 and this swivel plate 32 is formed to seal and coordinates, and this is solid
Determine plate 31 non-rotatable, and this swivel plate 32 is rotatable relative to this fixed plate 31.
This valve body 10 is provided with rotatable valve rod 40.The outside at this valve body 10, and this valve are stretched in one end of this valve rod 40
The outer end of bar 40 can be provided with handle or power connection has the executor that can order about its rotation.
Further say:
This valve body 10 is provided with swingle 50, and this swingle 50 upper end extend out to the outside of this valve body 10, lower end is positioned at this valve pocket
In 13, and the lower end of this swingle 50 connects this swivel plate 32.That is, this swingle 50 can drive this swivel plate 32 to rotate.
Shown in Fig. 5 and Fig. 6, the left part of this swivel plate 32 is provided with left through hole 321, right part is provided with right through hole 322.In conjunction with
Shown in Fig. 3 and Fig. 4, the lower surface of this fixed plate 31 is provided with arcuate groove 311, the bottom end of this arcuate groove 311 be provided with through extremely
Right intercommunicating pore 313 is had on the left connection hole 312 of this fixed plate 31 upper surface, and this fixed plate 31.Meanwhile, this left connection hole
The upper end of 312 connects this pressurization passageway 14, the upper end of this right intercommunicating pore 313 connects the upper end of this pressure release passage 15, and this pressure release is led to
The lower end in road 15 connects this lower chamber 132.And, this arcuate groove 311 and this right intercommunicating pore 313 are compatible with this left through hole 321 He
Right through hole 322.That is, after this swivel plate 32 rotates, it is possible to make the inner of this pressurization passageway 14 be communicated to this upper cavity 131, also
The upper end that this pressurization passageway 14 can be made to connect this pressure release passage 15 is communicated to this lower chamber 132 then.In other words, by this rotation
The rotation of flap 32, makes this piston 20 upper and lower side pressure experienced there occurs change.Pressure above this piston 20 is bigger
Time, this piston 20 moves down；Otherwise, when pressure below this piston 20 is bigger, this piston 20 moves up.
Non-rotatable nut 60 it is provided with, this screw thread that valve rod 40 bottom is provided with and this nut 60 matches in this valve pocket 13
41.That is, after this valve rod 40 rotates, this nut 60 moves up and down.Meanwhile, the upper end of this stage clip 22 withstands on this nut 60 upper and lower end
Withstand on this piston 20.That is, after this nut 60 moves up and down, this stage clip 22 is made to have the initial elastic force varied in size.
So, this piston 20 move up and down not only driving by this valve rod 40, and by this piston 20 two-way pressure
The impact of difference, the speed then turning on or closing is the most constant, and stress more equalizes.
More specifically:
The angle of the bearing of trend of the bearing of trend of this valve pocket 13 and this water inlet 11 is 135 °.So, this valve plate 21 is made to move
Time the resistance that is subject to close to 0, then extend this non-return hydraulic regulating valve service life.In other words, in this situation,
This non-return hydraulic regulating valve is adapted for mount on the pipeline of long-range conveyance fluid.Owing to valve body fluid passage is through state,
So valve turnover two-stage nitration does not has pressure reduction, that is does not substantially have resistance, urban water supply, natural gas conveying, Crude Oil Transportation can be replaced
Large-scale stop valve on pipe or ball valve.
This valve pocket 13 is a cylinder or Elliptic Cylinder.So, it is simple to the assembling of parts and processing, especially it is conveniently adjusted
The pressure differential of piston about 20.
Embodiment 2
Shown in Fig. 2, and the difference of embodiment 1 is: the bearing of trend of this valve pocket 13 and the extension of this water inlet 11
The angle in direction is 90 °.Now, in order to ensure the most laborsaving during switch, at this face passage 133 that dams, it is detachably and fixedly provided with one
Flow-rate adjustment set 1331.The middle part of this Flow-rate adjustment set 1331 was provided with water main channel 13311, and this Flow-rate adjustment overlaps 1331
Edge has the most penetrating adjustment hole 13312.Certainly, those adjustment holes 13312 can be multiple.So, adjust due to flow
Prepared by the material that the many employings in top of joint set 1331 are softer, such as, use rubber to prepare, then when switching this regulation valve, and one
Point water first circulates at adjustment hole 13312, from but the switch of regulation valve is the most laborsaving.In this situation, this non-return liquid
Pressure regulation valve is suitable as industrial regulation valve.
Wherein, the sectional area of this adjustment hole 13312 was less than the 1/20 of water main channel 13311 sectional area.Work as adjustment hole
13312 when being multiple, and the sectional area of adjustment hole 13312 refers to the sectional area summation of whole adjustment hole 13312.So, regulation
Hole 13312 is relatively reasonable to the regulation of flow rather than instead of water main channel 13311.
Further, the lower surface of this valve plate 21 is provided with the annular engagement groove 211 upwards caved in, adjustment hole 13312 to
Upper projection falls in the upwards projection of this annular engagement groove 211.Thus it is ensured that current first flow through in adjustment hole 13312.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every utilization
Equivalent structure or equivalence flow process that description of the invention and accompanying drawing content are made convert, or it is relevant to be directly or indirectly used in other
Technical field, be the most in like manner included in the scope of patent protection of the present invention.
