[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides a bursting disc blasting ceramic signal sensor with high transmission accuracy, which has the following beneficial effects:

[0023] 1. The bursting disc blasting ceramic signal sensor has high transmission accuracy. When connecting and installing a new sensor, it is only necessary to reverse the operation and insert the connecting wire between the corresponding fixed V block and the movable V block. At this time, tighten the turning handle, and the turning handle drives the trapezoidal slider to move, thereby driving the two movable V blocks to separate and move until their inclined surfaces press the wire part of the connecting wire against the area of ​​the teeth on the fixed V block. At this time, under the action of the teeth, the wire of the connecting wire can be firmly fixed, which can make the installation process of the new bursting disc sensor faster and easier, and avoid the time-consuming and labor-intensive manual connection of the wire in the traditional way. In addition, during the connection of the wire, the complicated operation makes the ceramic bursting disc susceptible to external collision or extrusion and rupture and damage, which to a certain extent improves the safety of the ceramic bursting disc installation and avoids unnecessary waste.

[0024] 2. The bursting disc blasting ceramic signal sensor has high transmission accuracy. When the ceramic bursting disc is broken by its limit pressure, the fuse is broken by the impact, and the original path becomes a short circuit. The path becomes a short circuit, which is actually a switch signal. The signal can be used to alarm and link, which can obtain effective feedback on the use of the ceramic bursting disc, avoiding the problem that the existing ordinary bursting disc only plays a role of pressure relief. When the bursting disc is actuated or ruptured, it cannot send a signal to notify the staff, affecting the use of the equipment.

[0025] 3. The bursting disc blasting ceramic signal sensor with high transmission accuracy can drive the screw to rotate by turning the turning handle, and the rotating screw can drive the trapezoidal slider to move downward, so that the two inclined surfaces of the trapezoidal slider no longer apply force to the movable V-block, so that the reset spring can drive the sliding column and the movable V-block to move toward the center position through the spring fixing plate, so that the two movable V-blocks can loosen the fixation of the connecting wire. At this time, the sealing sleeve can be separated from the hexagonal head sensor housing to bring out the connecting wire, which can make the ceramic bursting disc effectively and conveniently disassembled after use. This convenience can improve the work efficiency of replacing the ceramic bursting disc to a certain extent.

[0026] 4. The blasting ceramic signal sensor with high transmission accuracy uses two movable V-blocks to separate and move until their inclined surfaces press the wire part of the connecting line against the area of ​​the teeth on the fixed V-block. At this time, the wire of the connecting line can be firmly fixed under the action of the teeth. At the same time, due to the action of multiple teeth, the fixed V-block and the connecting line can be fully connected, avoiding the problem of small contact area at the wire connection position and low transmission stability.

[0027] 5. The blasting ceramic signal sensor with high transmission accuracy drives the trapezoidal slider to move through the rotating handle, thereby driving the two movable V blocks to separate and move until the inclined surface presses the conductor part of the connecting line, which can cause a certain degree of plastic deformation of the conductor, so that it is firmly fixed and avoids the situation of virtual connection of the wire end.

[0036] A quick connection assembly is provided on the hexagonal head sensor housing 2, and the quick connection assembly is used for quick installation and connection. The quick connection assembly includes a fixed V block 3, a movable V block 6, teeth 7, a reset spring 9 and a screw 13;

[0037] The fuse 12 in the sensor assembly is fixedly connected in the interlayer of the ceramic bursting disc 1, and both ends of the fuse 12 are fixedly connected with thick wires 11, and the two thick wires 11 are fixedly connected to the corresponding fixed V blocks 3 respectively;

[0038] The ceramic bursting disc 1 is fixedly connected to the front end of the hexagonal sensor housing 2, and the area of ​​the thick wire 11 in the installation cavity 19 is filled with sealant.

[0039] Furthermore, the quick connection assembly also includes a trapezoidal slider 10, which is made of Teflon. Two movable V-blocks 6 are respectively slidably connected to the inclined surfaces on both sides of the trapezoidal slider 10. The trapezoidal slider 10 is used to drive the two movable V-blocks 6 away from each other, and the two movable V-blocks 6 are used to clamp the connecting line 16.

[0040] Furthermore, the upper and lower sides of the two movable V-blocks 6 are fixedly connected with sliding posts 5. The hexagonal head sensor housing 2 has an installation cavity 19, and the installation cavity 19 is provided with sliding grooves 4 corresponding to the multiple sliding posts 5. The sliding posts 5 are slidably connected to the inner walls of the corresponding sliding grooves 4 respectively.

[0041] Furthermore, a plurality of spring grooves 8 are formed on the inner walls of the two installation cavities 19 , and spring fixing plates 17 are fixedly connected to the opposite sides of the corresponding two sliding posts 5 .

[0042] Furthermore, a plurality of reset springs 9 are respectively fixedly connected between the spring fixing plate 17 and the bottom wall of the corresponding spring slot 8 , and the reset springs 9 are used to drive the movable V-block 6 to reset.

[0043] Furthermore, two fixed V-blocks 3 are fixedly connected to the inner wall of the installation cavity 19 , and a plurality of teeth 7 are fixedly connected to the V-shaped surface of the fixed V-block 3 .

[0044] Furthermore, the plurality of teeth 7 are evenly arranged in a rectangular array, and the plurality of teeth 7 are used to improve the friction and conductivity with the connecting wire 16 .

[0045] Furthermore, a threaded hole 18 is provided on the trapezoidal slider 10 , and the screw 13 is threadedly connected in the threaded hole 18 , and both ends of the screw 13 are rotatably connected to the inner wall of the installation cavity 19 .

[0046] Furthermore, the upper end of the screw 13 rotates the outer surface of the hexagonal head sensor housing 2 and is fixedly connected with a turning handle 14 for driving the screw 13 to rotate. The screw 13 is used to drive the trapezoidal slider 10 to move up and down.

[0047] Furthermore, a sealing sleeve 15 is fixedly sleeved on the connecting wire 16 , the sealing sleeve 15 is matched with the lower end of the hexagonal head sensor housing 2 , and a sealing ring is provided between the sealing sleeve 15 and the lower end of the hexagonal head sensor housing 2 .

[0048] Furthermore, when the ceramic bursting disc 1 is under the working condition of 0.001-500Mpa, the ceramic bursting disc 1 can be broken into multiple pieces, and its force can disconnect the fuse 12;

[0049] When in use, both ends of the fuse 12 are connected to external signal equipment and equipment switches. Under normal circumstances, the wire is intact and a passage is formed at the two ends. When the ceramic bursting disc 1 is broken by its limit pressure, the fuse 12 is broken by the impact and the original passage becomes a short circuit. The passage becoming a short circuit is actually a switch signal. The signal can be used to alarm and link, which can effectively feedback the use of the ceramic bursting disc 1, avoiding the problem that the existing ordinary bursting disc only plays a pressure relief role. When the bursting disc is actuated or ruptured, it cannot send a signal to notify the staff, affecting the use of the equipment.

[0050] Furthermore, when replacement is needed, by turning the handle 14, the handle 14 can drive the screw 13 to rotate, and the rotating screw 13 can drive the trapezoidal slider 10 to move downward, so that the two inclined surfaces of the trapezoidal slider 10 no longer apply force to the movable V-block 6, so that the reset spring 9 can drive the slide column 5 and the movable V-block 6 to move toward the center position through the spring fixing plate 17, so that the two movable V-blocks 6 can loosen the fixation of the connecting line 16. At this time, the sealing sleeve 15 can be separated from the hexagonal head sensor housing 2, thereby bringing out the connecting line 16, which can enable the ceramic bursting disc 1 to be effectively and conveniently disassembled after use. This convenience can improve the work efficiency of replacing the ceramic bursting disc 1 to a certain extent.

[0051] Furthermore, when connecting and installing a new sensor, it is only necessary to reverse the operation and insert the connecting wire 16 between the corresponding fixed V-block 3 and the movable V-block 6. At this time, tighten the handle 14, and the handle 14 drives the trapezoidal slider 10 to move, thereby driving the two movable V-blocks 6 to separate and move until its inclined surface presses the wire part of the connecting wire 16 against the area of ​​the teeth 7 on the fixed V-block 3. At this time, under the action of the teeth 7, the wire of the connecting wire 16 can be firmly fixed, which can make the installation process of the new bursting disc sensor faster and easier, and avoid the time-consuming and labor-intensive manual connection of the wires in the traditional way. During the connection of the wires, the complicated operation makes the ceramic bursting disc 1 susceptible to external collision or extrusion and rupture and damage, which to a certain extent improves the safety of the ceramic bursting disc 1 during installation and avoids unnecessary waste.

[0052] Furthermore, the two movable V-blocks 6 are separated and moved until their inclined surfaces press the conductor part of the connecting wire 16 against the area of ​​the teeth 7 on the fixed V-block 3. At this time, under the action of the teeth 7, the conductor of the connecting wire 16 can be firmly fixed. At the same time, due to the action of multiple teeth 7, the fixed V-block 3 and the conductor of the connecting wire 16 can be fully connected, avoiding the problem of small contact area at the wire connection position and low transmission stability.

[0053] Furthermore, the trapezoidal slider 10 is driven to move by the rotating handle 14, thereby driving the two movable V-blocks 6 to separate and move until the inclined surface thereof presses the conductor part of the connecting wire 16, which can cause a certain degree of plastic deformation of the conductor, thereby firmly fixing it and avoiding the situation where the wire ends are loosely connected.

[0054] Working principle: When the ceramic bursting disc 1 is under the working condition of 0.001~500Mpa, the ceramic bursting disc 1 can break into multiple pieces, and its force can break the fuse 12;

[0055] When in use, both ends of the fuse 12 are connected to external signal equipment and equipment switches. Under normal circumstances, the wires are intact and a passage is formed at the two ends. When the ceramic bursting disc 1 is broken by its limit pressure, the fuse 12 is broken by the impact and the original passage becomes a short circuit. The passage becoming a short circuit is actually a signal of a switching quantity. The signal can be used to play an alarm and linkage role, which can enable the use of the ceramic bursting disc 1 to obtain effective feedback.

[0056] Furthermore, when replacement is needed, by turning the handle 14, the handle 14 can drive the screw 13 to rotate, and the rotating screw 13 can drive the trapezoidal slider 10 to move downward, so that the two inclined surfaces of the trapezoidal slider 10 no longer apply force to the movable V-block 6, so that the reset spring 9 can drive the slide column 5 and the movable V-block 6 to move toward the center position through the spring fixing plate 17, so that the two movable V-blocks 6 can loosen the fixation of the connecting wire 16, and at this time the sealing sleeve 15 can be separated from the hexagonal head sensor housing 2, thereby taking out the connecting wire 16.

[0057] Furthermore, when connecting and installing a new sensor, it is only necessary to reverse the operation and insert the connecting wire 16 between the corresponding fixed V-block 3 and the movable V-block 6. At this time, tighten the turning handle 14, and the turning handle 14 drives the trapezoidal slider 10 to move, thereby driving the two movable V-blocks 6 to separate and move until their inclined surfaces press the wire part of the connecting wire 16 against the area of ​​the teeth 7 on the fixed V-block 3. At this time, under the action of the teeth 7, the wire of the connecting wire 16 can be firmly fixed, which can make the installation process faster and easier when installing a new bursting disc sensor.
