Description
技术领域Technical Field
本实用新型涉及一种压力开关，尤其是应用在泵浦上，并针对流体压力进行控制的压力开关。The utility model relates to a pressure switch, in particular to a pressure switch which is applied to a pump and controls fluid pressure.
背景技术Background technique
一般管路会连接一泵浦，并通过所述泵浦加压管路内部的流体，使流体能突破高度差及特殊地形的限制，而顺利输送。而其中，为了能使管路内部保有一定的压力，所述泵浦会设有一压力开关，以侦测管路内部的压力变化，并控制所述泵浦运转与否。Generally, a pipeline is connected to a pump, and the pump pressurizes the fluid inside the pipeline, so that the fluid can break through the height difference and special terrain restrictions and be transported smoothly. In order to maintain a certain pressure inside the pipeline, the pump is equipped with a pressure switch to detect the pressure change inside the pipeline and control whether the pump is running or not.
现今的压力开关包含一衔接座、一膜片、一定位座、一开关模块及一控制组件，所述衔接座能用以连接管路，该膜片是密封地设置在该衔接座，该定位座及该开关模块是设置在该衔接座上，该定位座上会设置有一调控螺丝，且该定位座内部会设置抵接该调控螺丝的一压力弹簧，该控制组件是能线性移动地设置在该定位座内，并在所述压力弹簧的推顶下抵接该膜片。Today's pressure switches include a connecting seat, a diaphragm, a positioning seat, a switch module and a control component. The connecting seat can be used to connect the pipeline. The diaphragm is sealed on the connecting seat. The positioning seat and the switch module are arranged on the connecting seat. An adjusting screw is arranged on the positioning seat, and a pressure spring abutting the adjusting screw is arranged inside the positioning seat. The control component is linearly movable in the positioning seat and abuts the diaphragm under the push of the pressure spring.
当管路内部的压力不足时，所述压力开关会控制所述泵浦运转，使管路内部的压力上升；而当管路内部的压力上升并大于所述压力弹簧的阻力时，流体的压力会推动所述膜片，并使所述膜片推动所述控制组件并触动该开关模块，使该开关模块控制泵浦停止运转。When the pressure inside the pipeline is insufficient, the pressure switch will control the operation of the pump to increase the pressure inside the pipeline; and when the pressure inside the pipeline increases and is greater than the resistance of the pressure spring, the pressure of the fluid will push the diaphragm, causing the diaphragm to push the control component and trigger the switch module, causing the switch module to control the pump to stop running.
其中，为了防止所述调控螺丝在泵浦运转时受到震动影响而松脱移动，现今的制造厂商会在将所述调控螺丝调整完毕后，通过用固定剂胶合固定所述调控螺丝，但是通过固定剂胶合固定调控螺丝的方式不但可能导致用户后续难以旋动调控螺丝以调整压力值，而且经调整所述调控螺丝的位置后，会破坏所述固定剂的胶合固定效果，而导致所述调控螺丝仍会受到泵浦震动而产生位移，因此，用户仍需重新上固定剂以固定所述调控螺丝的位置，所以在使用上较为不便。Among them, in order to prevent the regulating screw from loosening and moving due to vibration when the pump is running, current manufacturers will glue and fix the regulating screw with a fixing agent after adjusting the regulating screw. However, the method of gluing and fixing the regulating screw with a fixing agent may not only make it difficult for the user to subsequently rotate the regulating screw to adjust the pressure value, but also destroy the gluing and fixing effect of the fixing agent after the position of the regulating screw is adjusted, causing the regulating screw to still be displaced due to pump vibration. Therefore, the user still needs to re-apply the fixing agent to fix the position of the regulating screw, which is inconvenient in use.

如图1至图3所示，该磁性开关模块30设置在该控制模块20的壳体21上，所述磁性开关模块30能依据所述控制组件22的磁吸组件221的位置进行开关的切换；其中，所述磁性开关模块30可以为磁簧开关或是霍尔传感器；此外，如图3所示，所述磁吸组件221具有一第一磁极222及一第二磁极223，所述磁吸组件221的第一磁极222是面向所述磁性开关模块30，而所述磁吸组件221的第二磁极223位于该第一磁极222相对所述磁性开关模块30的另一侧。As shown in Figures 1 to 3, the magnetic switch module 30 is arranged on the shell 21 of the control module 20, and the magnetic switch module 30 can switch the switch according to the position of the magnetic attraction component 221 of the control component 22; wherein, the magnetic switch module 30 can be a reed switch or a Hall sensor; in addition, as shown in Figure 3, the magnetic attraction component 221 has a first magnetic pole 222 and a second magnetic pole 223, the first magnetic pole 222 of the magnetic attraction component 221 faces the magnetic switch module 30, and the second magnetic pole 223 of the magnetic attraction component 221 is located on the other side of the first magnetic pole 222 relative to the magnetic switch module 30.
如图1所示，该外罩40是罩设在控制模块20上。As shown in FIG. 1 , the outer cover 40 is disposed on the control module 20 .
其中，如图1所示，控制模块20的壳体21一侧形成连通该调控螺孔212的一装配孔213，所述定位螺帽231能从所述装配孔213装入并嵌设在该壳体21的调控螺孔212中。As shown in FIG. 1 , a mounting hole 213 communicating with the adjusting screw hole 212 is formed on one side of the housing 21 of the control module 20 , and the positioning nut 231 can be inserted into the adjusting screw hole 212 of the housing 21 through the mounting hole 213 .
此外，如图1、图2所示，所述控制模块20的壳体21在该活动空间211的相对二侧分别形成连通的一活动长槽214，且所述控制组件22包含一抵顶件224以及一摆臂225，该抵顶件224是能线性移动地设置在该壳体21的活动空间211中，所述抵顶件224的相对二端分别延伸形成一支臂226，该摆臂225的一端枢设在该壳体21上，且所述磁吸组件221设置在该摆臂225的另一端，该摆臂225的中段处形成有二控制槽道227，所述抵顶件224的支臂226通过该壳体21的活动长槽214伸入该摆臂225的控制槽道227中。In addition, as shown in Figures 1 and 2, the shell 21 of the control module 20 forms a connected active long groove 214 on the two opposite sides of the active space 211, and the control component 22 includes a push-up member 224 and a swing arm 225. The push-up member 224 is linearly movably arranged in the active space 211 of the shell 21, and the two opposite ends of the push-up member 224 extend to form a branch arm 226 respectively. One end of the swing arm 225 is pivotally mounted on the shell 21, and the magnetic attraction component 221 is arranged at the other end of the swing arm 225. Two control grooves 227 are formed in the middle section of the swing arm 225. The support arm 226 of the push-up member 224 extends into the control groove 227 of the swing arm 225 through the active long groove 214 of the shell 21.
如图4所示，本实用新型压力开关应用在一泵浦50上，且所述磁性开关模块30是电性连接所述泵浦50，并能依据流体的压力大小控制所述泵浦50运转与否，而其中，如图5、图6所示，所述压力开关在泵浦50的管路内部的流体压力不足时，所述控制组件22的磁吸组件221位于该磁性开关模块30的磁感应范围中，所述磁性开关模块30呈导通状态，使所述泵浦50开始运转并对管路开始加压。As shown in FIG. 4 , the pressure switch of the utility model is applied to a pump 50 , and the magnetic switch module 30 is electrically connected to the pump 50 , and can control whether the pump 50 is running or not according to the pressure of the fluid. As shown in FIG. 5 and FIG. 6 , when the fluid pressure inside the pipeline of the pump 50 is insufficient, the magnetic attraction component 221 of the control component 22 is located in the magnetic induction range of the magnetic switch module 30 , and the magnetic switch module 30 is in a conducting state, so that the pump 50 starts to run and pressurizes the pipeline.
而在泵浦50运转的过程中，管路内部的流压力会逐渐上升，如图5至图8所示，当管路内部的流体压力超过所述压力弹簧233施加在所述抵顶件224的压力时，所述膜片13会变形并推动所述抵顶件224，使得所述抵顶件224的支臂226推动该摆臂225摆动；而如图7、图8所示，当流体压力达到一压力设定数值时，该摆臂225上的磁吸组件221会脱离所述磁性开关模块30的磁感应范围，并让所述磁性开关模块30呈断开状态，使所述泵浦50停止运转。During the operation of the pump 50, the flow pressure inside the pipeline will gradually increase. As shown in Figures 5 to 8, when the fluid pressure inside the pipeline exceeds the pressure applied by the pressure spring 233 to the push member 224, the diaphragm 13 will deform and push the push member 224, so that the support arm 226 of the push member 224 pushes the swing arm 225 to swing; and as shown in Figures 7 and 8, when the fluid pressure reaches a set pressure value, the magnetic attraction component 221 on the swing arm 225 will leave the magnetic induction range of the magnetic switch module 30, and the magnetic switch module 30 will be in a disconnected state, so that the pump 50 stops operating.
如图2、图3所示，用户能通过取下该外罩40并通过旋动所述调控螺丝232以调整所述压力弹簧233施加在所述抵顶件224的压力，进而能调控所述压力开关的磁性开关模块30断开时的压力设定数值，而其中，所述控制模块20的壳体21内部的调控螺孔212中嵌设的定位螺帽231，不但能让所述调控螺丝232不易受到泵浦50震动而产生松脱情形，同时能让用户能依据需求自行调控所述调控螺丝232的位置，以调整压力设定大小，且无须进行后续的防松脱处理，能有效提高所述压力开关的操作便利性。As shown in Figures 2 and 3, the user can remove the outer cover 40 and adjust the pressure applied by the pressure spring 233 to the push member 224 by rotating the adjusting screw 232, thereby adjusting the pressure setting value when the magnetic switch module 30 of the pressure switch is disconnected. Among them, the positioning nut 231 embedded in the adjusting screw hole 212 inside the shell 21 of the control module 20 not only makes the adjusting screw 232 less likely to loosen due to the vibration of the pump 50, but also allows the user to adjust the position of the adjusting screw 232 according to needs to adjust the pressure setting size without the need for subsequent anti-loosening treatment, which can effectively improve the operating convenience of the pressure switch.
另外，如图3所示，本实用新型压力开关的所述磁吸组件221的第一磁极222是面向所述磁性开关模块30，而所述磁吸组件221的第二磁极223是位在该第一磁极222相对所述磁性开关模块30的另一侧，因此能使所述磁吸组件221在相对所述磁性开关模块30移动的过程中，不易因所述磁吸组件221的磁力线影响而导致所述磁性开关模块30产生噪声的情形。In addition, as shown in FIG. 3 , the first magnetic pole 222 of the magnetic component 221 of the pressure switch of the utility model faces the magnetic switch module 30, and the second magnetic pole 223 of the magnetic component 221 is located on the other side of the first magnetic pole 222 relative to the magnetic switch module 30. Therefore, when the magnetic component 221 moves relative to the magnetic switch module 30, it is not easy for the magnetic switch module 30 to generate noise due to the influence of the magnetic lines of force of the magnetic component 221.
综上所述，本实用新型压力开关通过设置定位螺帽231，让所述调控螺丝232不易受到泵浦50震动而产生松脱情形，同时能让用户能依据需求自行调控所述调控螺丝232的位置，以调整压力设定大小，且无须进行后续的防松脱处理，能有效提高所述压力开关的操作便利性。In summary, the pressure switch of the utility model is provided with a positioning nut 231, so that the regulating screw 232 is not easily loosened due to the vibration of the pump 50, and at the same time allows the user to adjust the position of the regulating screw 232 according to needs to adjust the pressure setting size without the need for subsequent anti-loosening treatment, which can effectively improve the operating convenience of the pressure switch.
