The purpose of this utility model solves by the following technical programs:
This magnetic overcurrent Differential Pressure Unit, comprise the valve block position shelf, be provided with the overcurrent valve port in the valve block position shelf, the corresponding overcurrent valve block that can horizontally slip that also is provided with the overcurrent valve port is provided with the magnetic material that magnetic is repelled each other between described overcurrent valve block and the overcurrent valve port in the valve block position shelf.
Above-mentioned valve block position shelf is comprised of the first tubular position shelf that is interconnected and the second tubular location stand, and the inner chamber shaft core position of described the first tubular position shelf is fixedly installed axial valve block location cylinder; Be provided with the overcurrent valve port of undergauge on the left side of described the second tubular location stand, the right-hand member shaft core position of the second tubular location stand stretches out a boss to described overcurrent valve port place, is provided with the valve block positioning hole in the axle center of boss; Described overcurrent valve block is the plate-like lamellar body that two ends are provided with outrigger shaft, and the cavity outrigger shaft interior and the one end that the overcurrent valve block is installed on the first tubular position shelf stretches in the valve block location cylinder, and the outrigger shaft of the other end stretches in the valve block positioning hole of boss; Be provided with the magnetic material that magnetic is repelled each other in the outer rim of overcurrent valve block and the peripheral correspondence of overcurrent valve port.
Above-mentioned magnetic material is permanent-magnet material.
The plate-like lamellar body diameter of above-mentioned overcurrent valve block is greater than the overcurrent valve port diameter; And the plate-like lamellar body of described overcurrent valve block and the edge of overcurrent valve port can closely cooperate.
The utlity model has following beneficial effect:
Magnetic overcurrent Differential Pressure Unit of the present utility model is simple in structure, be easy to install, need not to regulate, mechanism's stable and reliable working performance, but its overcurrent valve block move left and right, contact close fit with the overcurrent valve port, this self closing stop valve is highly sensitive, effectively solve existing self closing stop valve and be higher than not closing problem not during ultrahigh pressure of working pressure because the narrow limitation of single structure causes pipeline pressure, and solved existing self closing stop valve outlet end self closing stop valve when 2 meters come off or break with the top hose end and be in the not problem of closed condition, overcome the low difficult problems such as unfavorable that produce of regulating of self closing stop valve sensitivity.

Fig. 2 is that whole valve was in ventilation normal working schematic representation after the utility model was installed in the valve body;
Fig. 3 is the schematic representation that valve body is in closed state among Fig. 2.
Wherein, 1,2 is magnetic material, 3, the overcurrent valve block, 4, the overcurrent valve port, and 5 is the front pipeline section of pipeline or valve body, and 6 is the first tubular position shelf, and 7 is the second tubular location stand, and 8 is the valve block location cylinder, and 9 is boss, and 10 is the valve block positioning hole.
Embodiment
The basic structure of magnetic overcurrent Differential Pressure Unit of the present utility model is: comprise the valve block position shelf, in the valve block position shelf, be provided with the overcurrent valve port, the corresponding overcurrent valve block that can horizontally slip that also is provided with the overcurrent valve port is provided with the magnetic material that magnetic is repelled each other between described overcurrent valve block and the overcurrent valve port in the valve block position shelf.Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is the structural representation of this novel wherein a kind of specific embodiment, its described valve block position shelf is comprised of the first tubular position shelf 6 that is interconnected and the second tubular location stand 7, and the inner chamber shaft core position of the first tubular position shelf 6 is fixedly installed axial valve block location cylinder 8; The right-hand member shaft core position that is provided with overcurrent valve port 4, the second tubulars location stand 7 of undergauge on the left side of the second tubular location stand 7 stretches out a boss 9 to described overcurrent valve port 4 places, is provided with valve block positioning hole 10 in the axle center of boss 9; Overcurrent valve block 3 is the plate-like lamellar body that two ends are provided with outrigger shaft, and the cavity outrigger shaft interior and the one end that overcurrent valve block 3 is installed on the first tubular position shelf 6 stretches in the valve block location cylinder 8, and the outrigger shaft of the other end stretches in the valve block positioning hole 10 of boss 9; Be provided with the magnetic material that magnetic is repelled each other in the outer rim of overcurrent valve block 3 and the peripheral correspondence of overcurrent valve port 4.Such as 1 among the figure and 2, this magnetic material 1,2 is permanent-magnet material, arranges circlewise in the outer rim of stream valve block 3 and the periphery of overcurrent valve port 4.The plate-like lamellar body diameter of overcurrent valve block 3 is greater than overcurrent valve port 4 diameters; And the plate-like lamellar body of described overcurrent valve block 3 and the edge of overcurrent valve port 4 can closely cooperate.Structural drawing shown in Figure 1 is that the utility model is packed in the front pipeline section 5 of pipeline or valve body.Schematic representation after the utility model is installed in the valve body such as Fig. 2 and Fig. 3, in normal working, because the pressure of overcurrent valve block 3 about equally, under the effect of homopolarity magnetic material 1 and 2 mutual expelling forces, overcurrent valve block 3 and overcurrent valve port 4 are in open mode, when in the pipeline or in the valve body since fault he when causing overcurrent valve block 3 both sides pressure reduction not wait, closes owing to differential pressure action causes overcurrent valve block 3 and overcurrent valve port 4 to overcome mutual expelling force.
What need statement is; the utility model magnetic overcurrent required for protection Differential Pressure Unit can not only be installed on as in the described valve body of Fig. 2-3; it also can be installed in any pipeline for delivery of fluid forms such as gas or liquid, can realize its function equally.
