[0022] like Figure 1 As shown, the utility model proposes: a magnetic encrypted thread gate valve, comprising;

[0023] Valve body 1, valve body 1 is made of non-magnetic material (non-magnetic material such as stainless steel, etc.), that is, it will not be attracted by magnets;

[0024] The gate 2, whose bottom end in the valve cavity of the valve body 1 passes upward through the top of the valve body 1, and a part of the gate 2 passes through the valve cavity (as shown in the figure, the gate 2 is centered inside the valve cavity and passes upward through the top of the valve body 1 at the bottom of the interior, and at the same time, the valve cavity, i.e., the water channel, passes through the lower side of the gate 2);

[0025] The sealing layer 3 is fixedly arranged in the gate 2, and the sealing layer 3 is a soft sealing material (such as rubber, etc.);

[0026] The gate plate 4 is attached to the sealing layer 3 and moves in a sealed manner in the gate channel 2. The valve body 1 is made of magnetic material {magnetic material such as carbon steel (containing iron) and the like};

[0027] A driving assembly 5 is installed on the valve body 1 and the gate plate 4 to drive the gate plate 4 to move up and down;

[0028] It also includes a plurality of annular sealing components 6 with magnetic attraction function, which are arranged in an annular shape outside the gate plate 4, arranged in another part of the gate channel 2 and built into the sealing layer 3 to improve the annular fitting force of the sealing layer 3 to the gate plate 4. The tendency force of the annular sealing components 6 on the valve body 1 causes the sealing layer 3 to deform toward it to improve the annular fitting force of the sealing layer 3 to the gate plate 4, providing an effect of increasing the airtightness (and as shown in the figure, the plurality of annular sealing components 6 are multiple).

[0029] A threaded opening 7 is provided on the valve cavity opening of the valve body 1 (as shown in the figure, it is provided at the left and right ends of the water passage mentioned above, and the threaded opening 7 is a threaded installation opening) for threaded installation.

[0030] like Figure 1 As shown, a plurality of annular sealing components 6 are provided in multiple groups and are evenly distributed in another part of the gate 2 from top to bottom (i.e., a plurality of annular sealing components 6 are evenly distributed in multiple groups from top to bottom in the gate 2 at the upper end of the valve cavity), thereby providing a multi-position pressurization effect and further improving the sealing stability.

[0031] In order to realize the implementation and use of the above-mentioned ring-sealed component 6, it is proposed that Figure 1 As shown, the specific structure and composition of the annular sealing component 6 can be as follows: the annular sealing component 6 includes a built-in cavity 61 arranged in the sealing layer 3 and a magnet block 62 fixed to the built-in cavity 61 (that is, a space for arranging the magnet block 62 is built-in inside the sealing layer 3, and a plurality of magnet blocks 62 are arranged around the gate plate 4). The magnet block 62 generates a magnetic attraction force on the gate plate 4, which can improve the compression effect of the sealing layer 3 attached to the gate plate 4 and enhance the sealing performance.

[0032] In order to implement the above-mentioned drive assembly 5, it is proposed that Figure 1 As shown, the specific structure and composition of the driving assembly 5 can be as follows: the driving assembly 5 includes a bracket 51 fixed to the top of the valve body 1 (the top of the valve body 1 can be connected and assembled by bolts, etc.);

[0033] The screw ring 52 (such as Figure 1 The screw ring 52 can be rotatably connected to the bracket 51 by a rolling bearing or the like);

[0034] A screw 53 fixed to the top of the gate plate 4 and connected to the inner thread of the screw ring (the screw 53 can be fixed to the top of the gate plate 4 by bolts or the like), and a hand wheel 54 fixed to the outside of the screw ring 52 (the screw ring 52 and the hand wheel 54 can be installed by welding or the like);

[0035] According to the above, when the operating hand wheel 54 rotates, the screw 53 rotates, and the bottom end of the screw 53 is fixed to the gate plate 4, and the gate plate 4 is fitted with the sealing layer 3 in the gate channel 2 to limit the rotation. At this time, the screw 53 moves up and down to drive the gate plate 4 to move;

[0036] In addition, the driving assembly 5 can be "the pneumatic actuator component proposed in the background technology for driving the gate valve to move up and down", and can also drive the gate plate 4 to move up and down.

[0037] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
