具体实施方式Detailed ways
下面结合附图和具体实施方式对本实用新型作进一步详细描述。Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
本实用新型如图1和图2所示，一种新型闸阀，由介质进口1、螺母2、密封垫圈3、螺栓4、阀杆5、阀盖6、阀体7、上挡板8、弹簧9、介质出口10、挡板销11、闸板12、下挡板13组成。As shown in Figure 1 and Figure 2, the utility model is a new type of gate valve, which consists of a medium inlet 1, a nut 2, a sealing washer 3, a bolt 4, a valve stem 5, a valve cover 6, a valve body 7, an upper baffle 8, a spring 9. It consists of a medium outlet 10, a baffle pin 11, a flashboard 12 and a lower baffle 13.
所述阀体7上包含介质进口1和介质出口10，阀体7的两端设有法兰盘，方便与其他管道连接。The valve body 7 includes a medium inlet 1 and a medium outlet 10, and flanges are provided at both ends of the valve body 7 to facilitate connection with other pipelines.
所述阀体7与阀盖6之间设有密封垫圈3，阀体7与阀盖6通过螺栓4固定连接，用螺母2锁紧。A sealing gasket 3 is provided between the valve body 7 and the valve cover 6 , and the valve body 7 and the valve cover 6 are fixedly connected by bolts 4 and locked by nuts 2 .
所述阀体7内设有上挡板8和下挡板13，上挡板8和下挡板13用挡板销11连接，并且可以绕着挡板销11旋转。The valve body 7 is provided with an upper baffle 8 and a lower baffle 13 , and the upper baffle 8 and the lower baffle 13 are connected by a baffle pin 11 and can rotate around the baffle pin 11 .
所述上挡板8和下挡板13都设有半球形凸台，在上挡板8和下挡板13的凸台上安装有弹簧9，在闸阀打开时，从介质进口1进来的高压介质冲向上挡板8和下挡板13的背面，在高压介质冲击力的作用下，上挡板8和下挡板13绕着挡板销11转动，弹簧9受到压缩，管道被打开两条通道，介质流经通道后从介质出口10流出，在闸阀打开瞬间有防止水锤的作用，在正常工作时，有缓减压力的作用。Both the upper baffle plate 8 and the lower baffle plate 13 are provided with hemispherical bosses, and springs 9 are installed on the bosses of the upper baffle plate 8 and the lower baffle plate 13. When the gate valve is opened, the high pressure coming in from the medium inlet 1 The medium rushes to the back of the upper baffle 8 and the lower baffle 13. Under the impact force of the high-pressure medium, the upper baffle 8 and the lower baffle 13 rotate around the baffle pin 11, the spring 9 is compressed, and the pipe is opened two Channel, the medium flows out from the medium outlet 10 after flowing through the channel, which has the function of preventing water hammer when the gate valve is opened, and has the function of reducing pressure during normal operation.
所述闸板12设为一锥型结构，大径的一端与阀杆5连接，闸板12与阀杆5同为一体。The gate 12 is configured as a cone structure, and one end with a large diameter is connected to the valve stem 5, and the gate 12 and the valve stem 5 are integrated.
