Description

流体安全遮断器Fluid safety circuit breaker 技术领域Technical field
本发明是一种安装在流体输送路径上的安全遮断器，当流体以不当的大流量于输送路径中冲流时，该遮断器可瞬间遮断流体输出。The present invention is a safety interrupter mounted on a fluid transport path that instantaneously interrupts fluid output when fluid flows in an undesirably large flow rate in the transport path.
背景技术Background technique
当流体有漏气的情形时，会以不当的大流量冲流于输送路径中。市面上各种安装于流体管路的流体超流阀于上述情形发生时提供自动遮断流体输出的功能，以维护流体使用的安全。待流体不当冲流的原因排除，再透过手动复归该超流阀的方式恢复流体输出。When the fluid leaks, it will flow into the conveying path with an inappropriate large flow rate. Various fluid superfluidic valves installed in the fluid line on the market provide the function of automatically interrupting the fluid output when the above occurs, to maintain the safety of fluid use. To avoid the cause of improper fluid flow, the fluid output is restored by manually resetting the super-flow valve.
如图1、图2，公知的流体超流阀10，大致包括供流体输流的阀管11、被限制在阀管11内一滚珠空间12中的一滚珠13、结合于阀管11下壁的调节器14、结合于阀管11上壁的复归开关15。在正常流体供流的情况下，流体从该阀管11的一端通过该滚珠空间12以及输出孔16向阀管11的另一端输出。当流体有漏气情形时，瞬间大流量的流体冲流于该阀管11中，冲流的压力将滚珠13推向输出孔16并将之封闭，从而阻断了流体输出。待流体冲流的原因被排除，向下按压该复归开关15，该复归开关15以内推杆151向下推开封闭该输出孔16的滚珠13，恢复输出孔16畅通。以工具旋转该调节器14，使其顺着螺纹线位移，被该调节器14顶持的滚珠13依照调节器14的上下位移而改变在阀管11中的水平高度，从而根据不同出口压力的流体冲流遮断。As shown in FIG. 1 and FIG. 2, a known fluid super-flow valve 10 generally includes a valve tube 11 for fluid supply, a ball 13 restrained in a ball space 12 in the valve tube 11, and a lower wall of the valve tube 11. The regulator 14 is coupled to the reset switch 15 on the upper wall of the valve tube 11. In the case of normal fluid supply, fluid is output from one end of the valve tube 11 through the ball space 12 and the output hole 16 to the other end of the valve tube 11. When there is a leak in the fluid, an instantaneous large flow of fluid flows into the valve tube 11, and the pressure of the rushing force pushes the ball 13 toward the output hole 16 and closes it, thereby blocking the fluid output. The reason for the flow of the fluid is eliminated, and the reset switch 15 is pressed down. The reset switch 15 pushes the ball 13 closing the output hole 16 downward by the inner push rod 151, and restores the output hole 16 to be unblocked. The adjuster 14 is rotated by a tool to be displaced along the thread, and the ball 13 held by the adjuster 14 changes the level in the valve tube 11 according to the up and down displacement of the adjuster 14, thereby depending on the outlet pressure. The fluid is interrupted by a flow.
上述流体超流阀10的调节器14和复归开关15是分开的两个组件，增加加工和组装的工序。此外，上述流体超流阀10安装于流体输送路径时，必需保持调节器14恒朝下，若将调节器14朝上，将使调整滚珠水平高度的功能失效。The regulator 14 and the reset switch 15 of the fluid super-flow valve 10 described above are two separate components, which increase the processing and assembly process. Further, when the fluid super-flow valve 10 is installed in the fluid transport path, it is necessary to keep the regulator 14 facing downward, and if the regulator 14 is directed upward, the function of adjusting the horizontal level of the ball is disabled.

A leak stop ring 34 is disposed between the end 42 and the ring 31.
一调节杆50，包括内部具有容置空间51的推顶部52以及连接于该推顶部 52的杆身53。该容置空间51设一弹簧56，该弹簧56的端部托住该滚珠221，该滚珠221的穿套部222与该弹簧56的端部彼此穿套结合，该弹簧56的弹力将滚珠221抵顶接触于该壁槽26。该调节杆50穿设于该按压杆40内，该推顶部52位于该容置空间41，该推顶部52的外壁与构成该容置空间41的内壁接触配合。该杆身53配有至少一止漏环57穿伸于该穿伸空间43，止漏环57与构成该穿伸空间43的内壁接触配合；该杆身53外壁与该杆管44内壁以螺纹段54彼此连接；该杆身53的端部设一工具槽55，可供手工具(图未示)通过该工具槽55旋转该杆身53，使该调节杆50沿着螺纹段54位移，改变该推顶部52在滚珠空间22内的位置。An adjustment rod 50 includes a push top 52 having an accommodating space 51 therein and is connected to the push top The shaft 53 of 52. The accommodating space 51 is provided with a spring 56. The end of the spring 56 supports the ball 221. The sleeve portion 222 of the ball 221 and the end of the spring 56 are sleeved with each other. The spring force of the spring 56 will be the ball 221 The top contact is in contact with the wall groove 26. The adjusting rod 50 is disposed in the pressing rod 40. The pushing top 52 is located in the accommodating space 41. The outer wall of the pushing top 52 is in contact with the inner wall constituting the accommodating space 41. The shaft 53 is provided with at least one leakage ring 57 extending through the penetration space 43. The leakage ring 57 is in contact with the inner wall constituting the penetration space 43. The outer wall of the shaft 53 and the inner wall of the rod 44 are threaded. The segments 54 are connected to each other; a portion of the shaft 53 is provided with a tool slot 55 through which the hand tool 53 can be rotated by the hand tool (not shown) to displace the adjusting rod 50 along the threaded portion 54. The position of the push top 52 within the ball space 22 is changed.
一压帽60，紧配合于该按压杆40的杆管44的外端。该压帽60具有一孔61供调节杆50的工具槽55显露，以便手工具接触该工具槽55。一弹簧62穿套于该按压杆40的杆管44外部而位于该套筒30的第二空间33，该弹簧62一端抵顶该环圈31，另一端抵顶该压帽60。该压帽60被按压，使按压杆40及调节杆50向该滚珠空间22的方向移动，使该按压杆40的端头42和该调节杆50的推顶部52向该滚珠空间22凸伸。该弹簧62于按压该压帽60的外力解除时，用以将压帽60复回，连带使按压杆40及该调节杆50复回原位。A pressure cap 60 is tightly fitted to the outer end of the rod tube 44 of the pressing rod 40. The pressure cap 60 has a hole 61 for the tool slot 55 of the adjustment lever 50 to be exposed so that the hand tool contacts the tool slot 55. A spring 62 is sleeved on the outside of the rod tube 44 of the pressing rod 40 and is located in the second space 33 of the sleeve 30. One end of the spring 62 abuts the ring 31 and the other end abuts the pressure cap 60. The pressing cap 60 is pressed to move the pressing lever 40 and the adjusting lever 50 in the direction of the ball space 22, so that the end 42 of the pressing lever 40 and the push top 52 of the adjusting lever 50 protrude toward the ball space 22. When the external force of pressing the pressure cap 60 is released, the spring 62 is used to return the pressure cap 60, and the pressing lever 40 and the adjusting lever 50 are brought back to the original position.
如图4，该弹簧56的弹力将滚珠221抵顶接触于该壁槽26，在流体的流量正常的情况下，流体从该阀管21的流体输入端23、输入孔231输入，通过该滚珠空间22从输出孔241及流体输出端24输出。As shown in FIG. 4, the spring force of the spring 56 abuts the ball 221 against the wall groove 26. When the flow rate of the fluid is normal, fluid is input from the fluid input end 23 of the valve tube 21 and the input hole 231 through the ball. The space 22 is output from the output aperture 241 and the fluid output end 24.
如图5，当瞬间大流量发生时，流体冲流于该阀管21中，冲流的压力将滚珠221推出该壁槽26并推向该输出孔241将之封闭，从而阻断了流体冲流输出，启动冲流遮断机制。当滚珠221被推向输出孔241，因滚珠221的穿套部222与该弹簧56的端部彼此穿套结合，因此滚珠221的位移将压缩并曲弯该弹簧56。As shown in Fig. 5, when an instantaneous large flow rate occurs, the fluid flows into the valve tube 21, and the pressure of the rushing force pushes the ball 221 out of the wall groove 26 and pushes it toward the output hole 241 to close it, thereby blocking the fluid rush. Stream output, initiates the flow interrupting mechanism. When the ball 221 is pushed toward the output hole 241, since the sleeve portion 222 of the ball 221 and the end portion of the spring 56 are coupled to each other, the displacement of the ball 221 will compress and bend the spring 56.
如图6，当流体冲流的原因排除后，可手动按压该压帽60，使按压杆40及调节杆50向该滚珠空间22的方向移动，该按压杆40的端头42和该调节杆50的推顶部52向该滚珠空间22凸伸，弹簧56被压缩，将封闭该输出孔241的滚珠221顶开，恢复输出孔241的畅通，解除冲流遮断机制。松释按压该压帽60的外力，该弹簧62释能，将该压帽60、按压杆40、调节杆50复归原位置。As shown in FIG. 6, after the cause of the fluid flow is removed, the pressure cap 60 can be manually pressed to move the pressing rod 40 and the adjusting rod 50 in the direction of the ball space 22, the end 42 of the pressing rod 40 and the adjusting rod The push top 52 of the 50 protrudes toward the ball space 22, and the spring 56 is compressed to open the ball 221 closing the output hole 241, thereby restoring the smooth flow of the output hole 241 and releasing the flow interruption mechanism. The external force of the pressing cap 60 is released, the spring 62 is released, and the pressing cap 60, the pressing lever 40, and the adjusting lever 50 are returned to the original position.
如图7，起子工具(图未示)的工作端通过该压帽60的孔61依附于该调节杆 50的工具槽55，带动该调节杆50旋转，使调节杆50依循螺纹段54位移，调整该推顶部52于滚珠空间22的凸伸量及该弹簧56的压缩量，可借此调整及修正该弹簧56的弹力；亦可借此调变该弹簧56对滚珠221的推抵力，从而改变冲流遮断的响应性，以根据不同压力的流体冲流遮断。例如：调高该弹簧56的压缩量，该弹簧56使滚珠221对壁槽26的抵顶力增加，供较大压力的流体可以通过，亦即需更高的冲流压力始能启动上述的冲流遮断机制；反之，调低该弹簧56的压缩量，该弹簧56使滚珠221对壁槽26的抵顶力降低，供较小压力的流体通过，稍高的冲流压力即可启动上述的冲流遮断机制。As shown in FIG. 7, the working end of the screwdriver tool (not shown) is attached to the adjusting rod through the hole 61 of the pressing cap 60. The tool slot 55 of the 50 drives the adjusting rod 50 to rotate, so that the adjusting rod 50 is displaced according to the thread segment 54 and adjusts the amount of protrusion of the pushing top 52 in the ball space 22 and the compression amount of the spring 56, thereby adjusting and correcting The spring force of the spring 56 can also be used to modulate the urging force of the spring 56 against the ball 221, thereby changing the responsiveness of the rushing interruption to interrupt the fluid according to different pressures. For example, the amount of compression of the spring 56 is increased, and the spring 56 increases the abutting force of the ball 221 against the wall groove 26, and the fluid for a larger pressure can pass, that is, a higher pressure is required to start the above-mentioned The flow interrupting mechanism; conversely, the compression amount of the spring 56 is lowered, the spring 56 reduces the abutting force of the ball 221 against the wall groove 26, and the fluid with a smaller pressure passes, and the slightly higher flushing pressure can start the above. The rushing interception mechanism.
图4至图7描述本发明流体安全遮断器20第一种使用范例，图8至图11描述该流体安全遮断器20第二种使用范例。两种使用范例的差别在于该复合开关25的位置。在第一种使用范例中，该复合开关25转向朝下，在第二种使用范例中，该复合开关25转向朝上。在第一种使用范例中的所有功效在第二种使用范例中均可重现。4 through 7 illustrate a first use example of the fluid safety interrupter 20 of the present invention, and Figs. 8 through 11 depict a second use example of the fluid safety interrupter 20. The difference between the two usage examples is the position of the composite switch 25. In the first use case, the composite switch 25 is turned downward, and in the second use case, the composite switch 25 is turned upward. All of the effects in the first usage paradigm can be reproduced in the second usage paradigm.
如图8，该弹簧56的弹力将滚珠221抵顶接触于该壁槽26，在流体的流量正常的情况下，流体从该阀管21的流体输入端23、输入孔231输入，通过该滚珠空间22从输出孔241及流体输出端24输出。As shown in FIG. 8, the spring force of the spring 56 abuts the ball 221 against the wall groove 26. When the flow rate of the fluid is normal, fluid is input from the fluid input end 23 of the valve tube 21 and the input hole 231 through the ball. The space 22 is output from the output aperture 241 and the fluid output end 24.
如图9，当瞬间大流量发生时，流体冲流于该阀管21中，冲流的压力将滚珠221推出该壁槽26并推向该输出孔241将之封闭，从而阻断了流体冲流输出，启动冲流遮断机制。As shown in Fig. 9, when an instantaneous large flow rate occurs, the fluid flows into the valve tube 21, and the pressure of the rushing force pushes the ball 221 out of the wall groove 26 and pushes it toward the output hole 241 to block the fluid, thereby blocking the fluid rush. Stream output, initiates the flow interrupting mechanism.
如图10，待流体冲流的原因排除后，可手动按压该压帽60，连动该按压杆40和调节杆50及弹簧56，将封闭该输出孔241的滚珠221向下推开，恢复输出孔241的畅通，解除冲流遮断机制。As shown in FIG. 10, after the fluid flow is removed, the pressure cap 60 can be manually pressed, the pressing lever 40 and the adjusting rod 50 and the spring 56 are interlocked, and the ball 221 that closes the output hole 241 is pushed downward to recover. The output hole 241 is unblocked, and the flow interruption mechanism is released.
如图11，起子工具(图未示)的工作端通过该压帽60的孔61依附于该调节杆50的工具槽55，带动该调节杆50旋转，使调节杆50依循螺纹段54位移，从而调整该推顶部52在滚珠空间22的位置。因该弹簧56介于滚珠221及推顶部52之间，当推顶部52位移时，将改变该弹簧56的压缩量。该推顶部52在滚珠空间22中的凸伸量愈多，该弹簧56的压缩量愈大，适用于较大压力的流体冲流遮断；反之，该推顶部52在滚珠空间22中的凸伸量愈少，该弹簧56的压缩量愈小，适用于较小压力的流体冲流遮断。 As shown in FIG. 11 , the working end of the screwdriver (not shown) is attached to the tool slot 55 of the adjusting rod 50 through the hole 61 of the pressing cap 60 , and the adjusting rod 50 is rotated to displace the adjusting rod 50 according to the thread segment 54 . Thereby, the position of the push top 52 in the ball space 22 is adjusted. Since the spring 56 is interposed between the ball 221 and the push top 52, the amount of compression of the spring 56 will change when the push top 52 is displaced. The greater the amount of protrusion of the push top 52 in the ball space 22, the greater the amount of compression of the spring 56, which is suitable for the flow of the larger pressure fluid; and conversely, the protrusion of the push top 52 in the ball space 22. The smaller the amount, the smaller the amount of compression of the spring 56, which is suitable for the flow of a small pressure to interrupt the flow.
如图3至图11，在本发明安全遮断器20第一实施例中，该流体输入端23及流体输出端24均为外螺纹管口结构。3 to 11, in the first embodiment of the safety interrupter 20 of the present invention, the fluid input end 23 and the fluid output end 24 are both externally threaded nozzle structures.
本发明的安全遮断器因该复合开关25的滚珠221以穿套部222与调节杆50中的弹簧56彼此穿套结合，且弹簧56的弹力将该滚珠221抵顶接触于阀管21的壁槽26，滚珠221在阀管21中被适当的限位，不会任意滚动，因此该安全遮断器可以呈水平、垂直、或任何角度使用。所谓的水平使用是指将流体输入端23及流体输出端24朝向左或右，该复合开关25如图所示朝上或朝下。所谓的垂直使用是指将流体输入端23及流体输出端24朝上或朝下，该复合开关25如图所朝左或朝右使用。换言之，该安全遮断器的使用方向不受限制。 The safety breaker of the present invention is coupled to the ball 221 of the composite switch 25 by the sleeve portion 222 and the spring 56 in the adjustment rod 50, and the elastic force of the spring 56 abuts the ball 221 against the wall of the valve tube 21. The groove 26, the ball 221 is properly restrained in the valve tube 21, and does not roll arbitrarily, so the safety interrupter can be used horizontally, vertically, or at any angle. The so-called horizontal use means that the fluid input end 23 and the fluid output end 24 are directed to the left or right, and the composite switch 25 is directed upward or downward as shown. By vertical use is meant that the fluid input 23 and the fluid output 24 are facing up or down, and the composite switch 25 is used as shown left or right. In other words, the direction of use of the safety interrupter is not limited.
