As shown in Figure 1：Lower resistance non-return hydraulic regulating valve, including valve body 10, the middle part of valve body 10 have valve pocket 13, and
The left part of the valve body 10 is provided with horizontal-extending water inlet 11, right part has same horizontal-extending delivery port 12, the water inlet
11 are connected with delivery port 12 by the face passage 133 that dams, the lower openings of the face passage 133 positioned at the valve pocket 13 of damming
Place.That is, the face passage 133 that dams is opened or closed, and forms connecting or blocking for the water inlet 11 and the delivery port 12, is realized
The switch of the lower resistance non-return hydraulic regulating valve.
The work that can be moved up and down and the valve pocket 13 is divided into upper cavity 131 and lower chamber 132 is provided with the valve pocket 13
Plug 20.Certainly, be necessarily arranged with the piston 20 and the valve pocket 13 the sealing ring that is engaged of side wall.The bottom of piston 20 is provided with
The valve plate 21 matched with the face passage 133 that dams, and the piston 20 is furnished with the stage clip 22 made it have to bottom offset trend.That is,
After the piston 20 is moved up and down, drive the valve plate 21 to move up and down, the face passage 133 that dams is opened or closed.
The side wall of the valve body 10 is provided with pressurization passageway 14 and pressure release passage 15, and the pressurization passageway 14 connects the water inlet 11
With the upper cavity 131.That is, the water in the water inlet 11 can enter in the pressurization passageway 14.
It is provided with fixed plate 31 and the swivel plate 32 for compressing together inside the upper cavity 131, the fixed plate 31 is above,
The swivel plate 32 is located at lower section.That is, the upper surface of the lower surface of the fixed plate 31 and the swivel plate 32 forms sealing and coordinates, and this is consolidated
Fixed board 31 is non-rotatable, and the swivel plate 32 is rotatable relative to the fixed plate 31.
The valve body 10 is provided with rotatable valve rod 40.One end of the valve rod 40 is stretched in the outside of the valve body 10, and the valve
The outer end of bar 40 can be provided with handle or power connector the actuator that can order about its rotation.
Further say：
The valve body 10 is provided with swingle 50, and the upper end of swingle 50 extend out to the outside of the valve body 10, lower end and is located at this
In valve pocket 13, and the lower end of the swingle 50 connects the swivel plate 32.That is, the swingle 50 can drive the swivel plate 32 to revolve
Turn.
With reference to shown in Fig. 5 and Fig. 6, the left part of the swivel plate 32 is provided with left through hole 321, right part and is provided with right through hole 322.With reference to
Shown in Fig. 3 and Fig. 4, the lower surface of the fixed plate 31 is provided with deep-slotted chip breaker 311, and the bottom end of the deep-slotted chip breaker 311 is provided with insertion extremely
Right intercommunicating pore 313 is provided with the left connection hole 312 of the upper surface of fixed plate 31, and the fixed plate 31.Meanwhile, the left connection hole
312 upper end connects the upper end that the pressurization passageway 14, the upper end of the right intercommunicating pore 313 connect the pressure release passage 15, and the pressure release is led to
The lower end in road 15 connects the lower chamber 132.And, the deep-slotted chip breaker 311 and the right intercommunicating pore 313 are compatible with the He of left through hole 321
Right through hole 322.That is, after the swivel plate 32 rotates, the inner of the pressurization passageway 14 can be made to be communicated to the upper cavity 131, also
The upper end that the pressurization passageway 14 can be made to connect the pressure release passage 15 is then communicated to the lower chamber 132.In other words, by the rotation
The rotation of flap 32, the pressure for being subject to the upper and lower side of piston 20 there occurs change.When the pressure of the top of piston 20 is larger
When, the piston 20 is moved down；Conversely, when the pressure of the lower section of piston 20 is larger, the piston 20 is moved up.
Non-rotatable nut 60 is provided with the valve pocket 13, the screw thread that the bottom of valve rod 40 is provided with and the nut 60 matches
41.That is, after the valve rod 40 rotation, the nut 60 is moved up and down.Meanwhile, the upper end of the stage clip 22 withstands on the upper and lower end of nut 60
Withstand on the piston 20.That is, after the nut 60 is moved up and down, make the stage clip 22 that there is initial elastic force of different sizes.
So, moving up and down for the piston 20 is not only driven by the valve rod 40, and by the two-way pressure of piston 20
Poor influence, the speed for then turning on or closing is more constant, and stress is more balanced.
More specifically：
The angle of the bearing of trend of the bearing of trend of the valve pocket 13 and the water inlet 11 is 135 °.So, the valve plate 21 is made
The resistance being subject to when mobile then extends the lower resistance non-return hydraulic regulating valve service life close to 0.In other words,
In this situation, the lower resistance non-return hydraulic regulating valve is adapted for mount on the pipeline of long-range trandfer fluid.Due in valve body
Fluid passage is through state, so valve passes in and out two sections without pressure difference, that is, can replace urban water supply, day without resistance substantially
Large-scale stop valve or ball valve in right gas conveying, Crude Oil Transportation pipe.
The valve pocket 13 is a cylinder or Elliptic Cylinder.So, it is easy to the assembling and processing of part, is especially conveniently adjusted
Pressure differential of the piston about 20.
Embodiment 2
With reference to shown in Fig. 2, and the difference of embodiment 1 is：The bearing of trend of the valve pocket 13 and the water inlet 11
The angle of bearing of trend is 90 °.It is more laborsaving when now, in order to ensure switch, removably fixed at the face passage 133 that dams
There is a flow adjusting set 1331.The middle part of Flow-rate adjustment set 1331 was provided with water main channel 13311, and the Flow-rate adjustment set
1331 edge is provided with adjustment hole 13312 penetrating up and down.Certainly, those adjustment holes 13312 can be multiple.So, due to
Prepared using softer material more than the top of Flow-rate adjustment set 1331, such as it is, standby using rubber system, then switching the regulating valve
When, a part of water first circulates from adjustment hole 13312, so as to the switch for being regulating valve is more laborsaving.In this situation, this is low
Resistance non-return hydraulic regulating valve is suitable as industrial regulating valve.
Wherein, the sectional area of the adjustment hole 13312 was no more than the 1/20 of the sectional area of water main channel 13311.Work as adjustment hole
13312 for it is multiple when, the sectional area of adjustment hole 13312 refers to the sectional area summation of whole adjustment holes 13312.So, adjust
Regulation of the hole 13312 to flow is relatively reasonable rather than instead of water main channel 13311.
Further, the lower surface of the valve plate 21 is provided with the annular engagement groove 211 of upward depression, adjustment hole 13312 to
Upper projection falls in the upward projection of the annular engagement groove 211.Thus it is ensured that current first flow through from adjustment hole 13312.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
Equivalent structure or equivalent flow conversion that every utilization the utility model specification and accompanying drawing content are made, or directly or indirectly fortune
Used in other related technical fields, similarly it is included in scope of patent protection of the present utility model.
