Description

Technical Field

[0001] The utility model relates to the technical field of emergency valves, in particular to an emergency valve for pouring a relay detonator. Background Art

[0002] The emergency valve for relay detonator pouring is a device that can quickly cut off or control the flow of fluid in an emergency. It is mainly used to prevent the pouring material from continuing to flow under abnormal circumstances during the pouring process of the relay detonator, thereby ensuring production safety and equipment integrity.

[0003] In order to improve the safety of the emergency valve when in use, the Chinese utility model patent with the publication number "CN212409506U" discloses an emergency valve for pouring a relay detonator, comprising a pouring valve housing, an emergency valve body, an upper pouring pipe joint, a material delivery hose, a middle pouring pipe joint and an emergency switch; wherein the emergency valve body is installed in a mounting groove provided in the pouring valve housing through a connecting piece; the emergency switch is screwed into the emergency switch mounting threaded hole; the material delivery hose is installed in the material delivery hose mounting channel; the upper pouring pipe joint is connected and installed in the upper pouring pipe joint mounting hole, and is communicated with the top end of the material delivery hose; the middle pouring pipe joint is installed in the middle pouring pipe joint mounting hole, and is communicated with the bottom end of the material delivery hose. The utility model rotates the emergency switch so that the screw part of the emergency switch rotates in the bolt in the emergency switch mounting threaded hole, so that the screw part of the emergency switch generates axial displacement, squeezes the material delivery hose until the portion corresponding to the material delivery hose and the emergency switch mounting threaded hole is flattened, so that the material delivery hose stops delivering material, thereby achieving emergency treatment;

[0004] However, in actual use, we found that in the above solution, the emergency valve body is installed into the installation groove of the casting valve shell by two screws, which makes its installation and subsequent disassembly and maintenance more cumbersome, reducing the actual loading and unloading efficiency. At the same time, it uses the screw part of the emergency switch to squeeze the feed hose, and the screw part may damage the feed hose due to the rotation and extrusion, thereby reducing the service life of the feed hose. Therefore, in order to solve these problems, we need to consider designing an emergency valve for the casting of relay detonators. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an emergency valve for pouring a relay detonator. In view of the problem of use, an emergency valve mechanism is provided, which drives the pressure plate to squeeze the feed hose by rotating the threaded block, thereby interrupting the feed. Compared with screw extrusion, the service life of the feed hose is guaranteed. At the same time, the emergency valve body can be quickly loaded and unloaded through the L-shaped limit block, two springs and the limit groove, thereby improving the loading and unloading efficiency.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 5 , an emergency valve for pouring a relay detonator, comprising a pouring valve housing 1, a mounting groove 2 being opened on the front side of the pouring valve housing 1, an upper pouring pipe joint 3 being provided at the upper end of the pouring valve housing 1, the lower end of the upper pouring pipe joint 3 penetrating the pouring valve housing 1 and extending to the inner top of the mounting groove 2, the upper end of the upper pouring pipe joint 3 being communicated with the upper pouring pipe, a middle pouring pipe joint 4 being provided at the lower end of the pouring valve housing 1, the upper end of the middle pouring pipe joint 4 penetrating the pouring valve housing 1 and extending to the inner bottom of the mounting groove 2, the lower end of the middle pouring pipe joint 4 being communicated with the middle pouring pipe, a material delivery hose 5 being provided between the outer side of the lower end of the upper pouring pipe joint 3 and the outer side of the upper end of the middle pouring pipe joint 4, the material delivery hose 5 being a silicone tube;

[0023] Among them, it also includes an emergency valve mechanism, which is used to control the material delivery of the material delivery hose 5. The emergency valve mechanism includes an emergency valve body 6, a threaded through groove 7 is provided on the front side of the emergency valve body 6, and a threaded block 8 is connected to the threaded through groove 7. A rectangular sliding groove is provided on the rear side of the emergency valve body 6, and a pressure plate 9 that can move back and forth is slidably connected in the rectangular sliding groove. The pressure plate 9 cooperates with the material delivery hose 5. By controlling the pressure plate 9 to move backward, the material delivery hose 5 can be squeezed to cut off the material delivery. The front side of the pressure plate 9 is rotatably connected to the rear side of the threaded block 8. A rectangular inner groove 10 is provided on the front side of the emergency valve body 6. An L-shaped limit block 11 that can move left and right is provided in the rectangular inner groove 10. The right side of the L-shaped limit block 11 is elastically connected to the inner wall of the rectangular inner groove 10 by two springs 12;

[0024] Among them, a limiting groove 13 is provided on the left inner wall of the mounting groove 2, the left end of the L-shaped limiting block 11 passes through the left inner wall of the rectangular inner groove 10 and extends into the limiting groove 13, and a guide rod 14 is fixedly connected between the left and right inner walls of the rectangular inner groove 10. The guide rod 14 is slidingly connected to the L-shaped limiting block 11. A handle 15 is fixedly connected to the front side of the emergency valve body 6, and a hexagonal inner groove 16 is provided on the front side of the threaded block 8 to facilitate the rotation of the threaded block 8.

[0025] In the present invention, when it is necessary to cut off the feeding of the feeding hose 5, the threaded block 8 is rotated by a tool to drive the pressing plate 9 to move backward. Since the threaded block 8 and the pressing plate 9 are rotatably connected, and the rectangular sliding groove can limit the rotation of the pressing plate 9, the pressing plate 9 will not rotate when moving. During the backward movement, the pressing plate 9 will continuously squeeze the feeding hose 5. When it is fully squeezed, the feeding of the feeding hose 5 can be interrupted. At the same time, compared with the traditional screw extrusion, the extrusion of the pressing plate 9 will not cause damage to the feeding hose 5, thereby ensuring the safe use of the feeding hose 5.

[0026] When the emergency valve body 6 needs to be maintained, push the L-shaped limit block 11 to the right so that the left end of the L-shaped limit block 11 disengages from the limit groove 13, and then pull the handle 15 forward to remove the entire emergency valve body 6 from the installation groove 2. During subsequent installation, push the L-shaped limit block 11 to the right so that it is completely in the rectangular inner groove 10. At this time, the two springs 12 will be compressed, and then the emergency valve body 6 is aligned with the installation groove 2 and slowly inserted. During the insertion, since the L-shaped limit block 11 is against the inner wall of the installation groove 2, there is no need to continue to apply thrust to the L-shaped limit block 11. When the left end of the L-shaped limit block 11 moves to the limit groove 13, due to the action of the two springs 12, the L-shaped limit block 11 will automatically move to the left, and its left end will be inserted into the limit groove 13. In this way, the installation of the emergency valve body 6 is completed. The entire installation and disassembly process is relatively convenient and quick, effectively improving the actual loading and unloading efficiency.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
