Description

Technical Field

[0001] The utility model belongs to the technical field of rupture valves, and particularly relates to a DN25 internal thread rupture valve. Background Technique

[0002] A rupture valve is a device used to prevent leakage accidents caused by accidental rupture of pipelines. It is also known as an emergency disconnection device. It belongs to the weak connection point of the entire transmission link. When the set conditions are met, it will automatically disconnect the pipeline connection, and the intermediate medium will be self-sealed in the pipeline.

[0003] The existing rupture valves on the market have the following problems in application: When the traditional rupture valve is in use, it generally needs to be fixed in the required position first. Since the internal thread rupture valve is divided into two parts during fixation, the other half of the internal thread rupture valve is likely to fall off during installation, making the installation rather difficult. Content of the Utility Model

[0004] The purpose of the utility model is to provide a DN25 internal thread rupture valve to solve the technical problems raised in the background technique.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows: A DN25 internal thread rupture valve, wherein the side of the housing is fixedly connected with mounting plates. The number of the mounting plates is two. Rupture wire holes are formed on the surface of the mounting plates. M6 rupture wires penetrate through the rupture wire holes. The rupture wire holes are symmetrically distributed. Safety bolt grooves are formed on the surface of the mounting plates. The safety bolt grooves are symmetrically distributed. M6 safety bolts penetrate through the safety bolt grooves.

[0006] Preferably, hex nuts are provided on the side of the housing, and the number of the hex nuts is two.

[0007] Preferably, M6 nuts are sleeved outside the M6 rupture wires, and M6 nuts are sleeved outside the M6 safety bolts.

[0008] Preferably, a rod body is embedded inside the housing. A tetrafluoro seal is sleeved outside the rod body. A disconnection-sealing tetrafluoro valve flap is sleeved outside the rod body. The number of the disconnection-sealing tetrafluoro valve flaps is two.

[0010] Preferably, an O-shaped spring is embedded inside the tetrafluoro seal, and a connecting spring is provided on the side of the disconnection-sealing tetrafluoro valve flap.

[0011] A DN25 internal thread breaking valve of the present utility model has the following advantages: for the DN25 internal thread breaking valve, there are two additional mounting plates on the side of the housing. The surface of the mounting plate is provided with breaking wire holes, which are symmetrically distributed. The surface of the mounting plate is provided with safety bolt grooves, and M6 breaking wires penetrate through the safety bolt grooves, which are symmetrically distributed. M6 safety bolts penetrate through the safety bolt grooves. Before use, the M6 safety bolts are installed inside the mounting plate through the safety bolt grooves, and the breaking wires are installed inside the mounting plate through the breaking wire holes. At this time, the two ends of the housing of the internal thread breaking valve can be fixed together. And because of the safety bolt grooves, it is convenient to load and unload the M6 safety bolts. When installing the internal thread breaking valve at this time, one end of the internal thread breaking valve can be prevented from falling off during installation, making the installation more convenient.

[0022] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a DN25 internal thread break valve of the present utility model with reference to the drawings.

[0023] As Figures 1-3As shown in the figure, a DN25 internal thread breaking valve of the present utility model includes a housing 2. On the side of the housing 2, there are fixedly connected mounting plates 14. The number of mounting plates 14 is two. On the surface of the mounting plates 14, there are provided breaking wire holes 11. Inside the breaking wire holes 11, M6 breaking wires 4 penetrate through. The breaking wire holes 11 are symmetrically distributed. On the surface of the mounting plates 14, there are provided safety bolt grooves 12. The safety bolt grooves 12 are symmetrically distributed. Inside the safety bolt grooves 12, M6 safety bolts 6 penetrate through.

[0024] On the side of the housing 2, there are two hexagonal nuts 1. By installing hexagonal bolts on the side of the housing 2, the breaking valve can be installed in the required place through the hexagonal bolts.

[0025] An M6 nut 5 is sleeved outside the M6 breaking wire 4, and an M6 nut 5 is sleeved outside the M6 safety bolt 6. By sleeving nuts outside the M6 breaking wire 4 and the M6 safety bolt 6 and tightening the nuts on the M6 breaking wire 4 and the M6 safety bolt 6, the M6 breaking wire 4 and the M6 safety bolt 6 can be fixed at this time.

[0026] Inside the housing 2, there is an inlaid rod body 15. Outside the rod body 15, there is a tetrafluoro seal 9 sleeved. Outside the rod body 15, there are two breaking-sealing tetrafluoro valve flaps 8 sleeved. By installing the rod body 15 inside the housing 2, installing the tetrafluoro seal 9 outside the rod body 15, and sleeving the sealing tetrafluoro valve flaps outside the rod body 15, when the breaking valve is pulled off, the tetrafluoro seal 9 moves under the drive of the breaking-sealing tetrafluoro valve flap 8. At this time, the broken internal thread breaking valve can be sealed.

[0027] A retaining ring 10 is sleeved outside the rod body 15. On the surface of the retaining ring 10, there is a circlip 7. By sleeving the retaining ring 10 outside the rod body 15, the circlip can prevent the retaining ring 10 from shaking inside the internal thread seat breaking valve.

[0028] An O-ring spring 13 is inlaid inside the tetrafluoro seal 9, and a connecting spring 3 is provided on the side of the breaking-sealing tetrafluoro valve flap 8. By inlaying the O-ring spring 13 inside the tetrafluoro seal 9 and installing the connecting spring 3 on the side of the breaking-sealing tetrafluoro valve flap 8, when the internal thread breaking valve breaks, the O-ring spring and the connecting spring 3 expand. At this time, the breaking-sealing tetrafluoro valve flap 8 can be driven to seal both sides of the breaking valve.

[0029] Working principle of the DN25 internal-thread breaking valve: When applying this internal-thread breaking valve, install the M6 safety bolt 6 inside the mounting plate 14 through the safety bolt groove 12, and install the breaking wire inside the mounting plate 14 through the breaking wire hole 11. At this time, the two end shells 2 of the internal-thread breaking valve can be fixed together. And due to the opening of the safety bolt groove 12, it is convenient to load and unload the M6 safety bolt 6. Before installation, unscrew the M6 nut 5 to remove the M6 safety bolt 6. At this time, install the internal-thread breaking valve. During installation, it can prevent one end of the internal-thread breaking valve from falling off, making the installation more convenient. After installing the two shells 2, install the internal-thread breaking valve at the required position through the hexagon nut 1, and connect it to the position where it needs to be used through the hexagon nut 1 at the other end. If the staff forgets to remove the internal-thread breaking valve at the other end after use and directly pulls away one end of the breaking valve, at this time, the breaking valve can be broken by the M6 breaking wire 4. At the same time, when the internal-thread breaking valve breaks, the O-shaped spring and the connecting spring 3 expand. At this time, it can drive the broken-sealing tetrafluoro valve flap 8 to seal both sides of the breaking valve, preventing the liquid at both ends of the breaking valve from flowing out continuously.

[0030] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
