All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
As shown in fig. 1 and 2, the valve core operation position memory device is applied to a liquid valve 1, wherein the liquid valve 1 comprises: a spool 2, the spool 2 including an adjustment surface 21 for adjusting the spool position; wherein, case working position memory device 3 includes: a moving body 8 and a controller; the moving body 8 is configured to be in contact with the surface of the adjustment surface; the controller is electrically connected to the moving body 8, and is configured to: the moving position of the moving body 8 is controlled to record or adjust the position of the spool 2.
In use of the present embodiment, the valve core operating position memory device 3 is required to be assembled at an assembling position of the liquid valve 1, which is generally preset and fixed. After the valve core working position memory device 3 is fixed in the liquid valve 1, different contact positions of the moving body 8 and the adjusting surface 21 correspond to different positions of the adjusting surface 21, so as to correspond to different valve core opening and closing requirements.
When the liquid valve 1 is a multi-way valve, for example, the micro-change of the valve core position can cause the working condition of the multi-way valve to change, and each operator is generally familiar with the opening and closing degree of the valve core commonly used by the operator. When the operator needs to record the familiar opening and closing degree of the valve core, the valve core working position memory device 3 is assembled at the assembling position in the liquid valve 1. Then the operator adjusts the valve core 2 to a familiar position, the position change of the valve core 2 can change the contact position of the moving body 8 and the adjusting surface 21, and after the contact position of the moving body 8 and the adjusting surface 21 is stable and does not change, the controller is used for recording the position of the moving body 8 or locking the position of the moving body 8; the recorded or locked moving body 8 corresponds to a specific valve core opening and closing requirement.
In this embodiment, when the contact position between the surface 21 to be adjusted and the moving body 8 is stable during the process of contacting the surface 21 to be adjusted with the moving body 8, that is, the contact between the moving body 8 and the surface 21 to be adjusted is in a stable state, the controller records or locks the position of the moving body 8 at this time. In this embodiment, the controller can control the position of the moving body 8, so as to obtain different opening and closing requirements of the valve element. When the liquid valve 1 needs to be regulated to meet different valve core opening and closing requirements, the valve core working position memory device which is recorded or locked with the moving body 8 is assembled at the assembling position of the liquid valve 1, and then the adjusting surface 21 of the valve core 2 is moved to ensure that the valve core 2 is contacted with the moving body 8 stably, so that the required valve core opening and closing requirements can be directly obtained.
In some embodiments, when the spool operating position memory device is used to record a single trim position, the spool operating position memory device is assembled at the assembly location of the fluid valve; the controller is further configured to: the moving position of each moving body is locked.
When the valve core is in use, the adjusting protrusions of the moving bodies face to the adjusting surfaces of the valve cores, an operator starts to adjust the positions of the valve cores, the adjusting surfaces of the valve cores are in contact with the adjusting protrusions, the valve core adjusting surfaces drive the moving bodies to move when moving until the valve cores are adjusted to be familiar with the opening and closing requirements of the valve cores by the operator, and when all the moving bodies and the adjusting surfaces reach a stable contact state, the controller locks all the moving bodies, and at the moment, the surfaces formed by all the moving bodies are consistent with the positions of the adjusting surfaces. And then the valve core working position memory device can be taken out from the assembly position, if a follow-up operator wants to quickly adjust the valve core to the familiar valve core opening and closing requirements, the valve core working position memory device is assembled at the assembly position, the track of all moving bodies describes the position of the adjusting surface, then the position of the valve core is directly adjusted until the adjusting surface is contacted with each moving body and reaches a stable contact state, and at the moment, the position of the adjusting surface is the familiar valve core opening and closing requirements recorded by the previous operator. The stable contact state of such embodiments may refer to: the adjustment surface interacts with each movable body until the position of each movable body is no longer changed, at which point the movable body and the adjustment surface reach a stable contact state.
In some embodiments, the controller is further configured to: recording displacement data of each moving body under different valve core opening and closing requirements; and controlling the moving position of the moving body according to the displacement data so as to meet the opening and closing requirements of the valve core.
When an operator needs to adjust the adjusting surface according to the opening and closing requirements of the valve core, the controller calls displacement data corresponding to the operator; and controlling the moving position of the moving body according to the displacement data so as to meet the opening and closing requirements of valve cores required by operators. When the valve element working position memory device is used, a single operator or a plurality of operators can record displacement data of a plurality of moving bodies in the same valve element working position memory device, and different displacement data correspond to different adjusting surface positions, namely, different valve element opening and closing requirements. When the valve core working position memory device is required to be used for adjusting a required adjusting surface, the controller calls corresponding displacement data, then controls the moving bodies to move to the positions corresponding to the displacement data and locks all the moving bodies, loads the valve core working position memory device into the assembly position of the liquid valve, and directly adjusts the valve core position to enable the adjusting surface to be in contact with each moving body and achieve a stable contact state, so that the required valve core opening and closing requirement is obtained. When the valve core needs to be adjusted to other valve core opening and closing demands, corresponding displacement data are called. In this embodiment, a single memory card can be used for multiple valve core opening and closing requirements. The stable contact state of such embodiments may refer to: the direction of the adjusting surface is adjusted towards the moving body, the adjusting surface is contacted with the moving body until the adjusting surface can not move towards the moving body any more, and then the adjusting surface and the moving body reach a stable contact state.
