Description
技术领域technical field
本实用新型涉及的是一种膨胀阀气箱头部件中，传动片的运动能够与膜片保持同轴度，使运动更加可靠的传动片导向结构，属于膨胀阀气箱头部件的内部结构。The utility model relates to an expansion valve gas box head part, the movement of the transmission piece can maintain coaxiality with the diaphragm, so that the movement is more reliable. The transmission piece guide structure belongs to the interior of the expansion valve gas box head part structure.
背景技术Background technique
在现有技术中，膨胀阀气箱头部件主要由传动片1和膜片2与气箱盖3和气箱座4一起装配而成，其中传动片1在气箱头中处于不固定的活动位置，这就容易导致产品在装配完成后，传动片的位置会偏离中心，传动片在传递压力的过程中，容易使传动杆偏斜，导致气箱头内部的感温力传递不稳定，直接影响到空调系统运行的可靠性。如图1所示，在理想状态下，膜片1、传动片1、上传动杆5、下传动杆6、钢球7应处于同一轴线上。当气箱头感受到蒸发器出口处的过热度时，气箱头内部封入介质会给膜片2产生一个力，此力通过传动片1、上传动杆5、下传动杆6进行传递，然后作用在钢球7上，使钢球7产生向上或向下的运动，从而控制节流口的大小，使适当的冷媒流向蒸发器中；而实际由于传动片在气箱头中相对与膜片可以移动，会使传动片的轴心和哝片的轴心不重合，导致上传动杆偏斜，从而使力在传递过程中不稳定，钢球7无法可靠、稳定地控制节流口的大小。In the prior art, the expansion valve air box head part is mainly assembled by the transmission plate 1 and the diaphragm 2 together with the air box cover 3 and the air box seat 4, wherein the transmission plate 1 is in an unfixed movement in the air box head position, which will easily cause the position of the transmission piece to deviate from the center after the product is assembled. Affect the reliability of air conditioning system operation. As shown in Figure 1, in an ideal state, the diaphragm 1, the transmission plate 1, the upper transmission rod 5, the lower transmission rod 6, and the steel ball 7 should be on the same axis. When the air box head feels the superheat at the outlet of the evaporator, the medium sealed inside the air box head will generate a force on the diaphragm 2, and this force is transmitted through the transmission plate 1, the upper transmission rod 5, and the lower transmission rod 6, and then It acts on the steel ball 7 to make the steel ball 7 move upwards or downwards, thereby controlling the size of the orifice, so that the appropriate refrigerant flows into the evaporator; in fact, because the transmission plate is opposite to the diaphragm in the air box head It can be moved, which will make the axis of the transmission plate and the axis of the slit do not coincide, resulting in the deflection of the upper transmission rod, so that the force is unstable during the transmission process, and the steel ball 7 cannot reliably and stably control the size of the orifice. .
发明内容Contents of the invention
本实用新型的目的在于克服上述存在的不足，而提供一种改进的、对传动片进行导向作用的膨胀阀气箱头内传动片导向结构。它包括由传动片和膜片与气箱盖和气箱座一起装配成的气箱头部件，在传动片与气箱座之间设置有导向弹性元件。The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide an improved guide structure for the transmission plate in the expansion valve gas tank head that guides the transmission plate. It includes an air box head part assembled by a transmission plate and a diaphragm, an air box cover and an air box seat, and a guiding elastic element is arranged between the transmission plate and the air box seat.
所述的导向弹性元件位于传动片的下方，且被固定在气箱座或传动片上。The guide elastic element is located under the transmission piece and is fixed on the air box seat or the transmission piece.
本实用新型由于在传动片与气箱座之间安装有一导向弹性元件，保证了膜片轴心和传动片轴心的同轴度在要求范围内，在传递力的过程中，上传动杆不会产生偏斜，力的传递稳定，使钢球向上或向下的运动变得更加可靠、更加稳定地控制冷媒流量；具有结构简单，设计合理，使用效果好等特点。In the utility model, since a guiding elastic element is installed between the transmission plate and the air box seat, the coaxiality between the axis of the diaphragm and the axis of the transmission plate is guaranteed to be within the required range, and the upper transmission rod does not There will be deflection, and the transmission of force is stable, so that the upward or downward movement of the steel ball becomes more reliable, and the refrigerant flow is controlled more stably; it has the characteristics of simple structure, reasonable design, and good use effect.

具体实施方式Detailed ways
下面将结合附图对本实用新型作详细的介绍：图2所示，本实用新型主要包括有由传动片1和膜片2与气箱盖3和气箱座4一起装配成的气箱头部件，在传动片1与气箱座4之间设置有导向弹性元件8。The utility model will be described in detail below in conjunction with the accompanying drawings: As shown in Figure 2, the utility model mainly includes an air box head part assembled with a transmission plate 1 and a diaphragm 2, an air box cover 3 and an air box seat 4 , A guiding elastic element 8 is arranged between the transmission plate 1 and the air box seat 4 .
所述的导向弹性元件8位于传动片1的下方，且被固定在气箱座4或传动片1上。本实用新型由于增加了导向弹性元件8，使传动片1在气箱座4中的运动只有上下运动，保证了传动片1与膜片2的同轴度要求。当气箱头感受到蒸发器出口处的过热度时，气箱头内部封入介质会给膜片2产生一个力F，此力通过传动片1、上传动杆5、下传动杆6进行传递，然后作用在钢球7上，使钢球产生向上或向下的运动。在传递力F的过程中，上传动杆5不会产生偏斜，力F传递稳定，使钢球7向上或向下的运动变得可靠，使适当的冷媒流入蒸发器中。图3所示，本实用新型所述的导向弹性元件8被固定在气箱座4上；图4所示，所述的导向弹性元件8被固定在传动片1上。本实用新型由于在传动片与气箱座之间安装有一导向弹性元件，保证了膜片轴心和传动片轴心的同轴度在要求范围内，在传递力的过程中，上传动杆不会产生偏斜，力的传递稳定，使钢球向上或向下的运动变得更加可靠、更加稳定地控制冷媒流量。The guide elastic element 8 is located below the transmission piece 1 and is fixed on the air box seat 4 or the transmission piece 1 . Due to the addition of the guiding elastic element 8 in the utility model, the movement of the transmission plate 1 in the air box seat 4 can only move up and down, which ensures the coaxiality requirement of the transmission plate 1 and the diaphragm 2 . When the air box head feels the superheat at the outlet of the evaporator, the medium sealed inside the air box head will generate a force F on the diaphragm 2, and this force is transmitted through the transmission plate 1, the upper transmission rod 5, and the lower transmission rod 6. Then act on the steel ball 7 to make the steel ball move upward or downward. In the process of transmitting the force F, the upper transmission rod 5 will not be deflected, and the force F is transmitted stably, so that the upward or downward movement of the steel ball 7 becomes reliable, and proper refrigerant flows into the evaporator. As shown in FIG. 3 , the guide elastic element 8 described in the present invention is fixed on the air box seat 4 ; as shown in FIG. 4 , the guide elastic element 8 is fixed on the transmission plate 1 . In the utility model, since a guiding elastic element is installed between the transmission plate and the air box seat, the coaxiality between the axis of the diaphragm and the axis of the transmission plate is guaranteed to be within the required range, and the upper transmission rod does not There will be deflection, and the transmission of force is stable, so that the upward or downward movement of the steel ball becomes more reliable and more stable to control the flow of refrigerant.
