技术领域Technical Field
本发明属于节流式流量计技术领域，尤其涉及一种能够便于更换节流孔板的节流式流量计。The invention belongs to the technical field of throttling flowmeters, and in particular relates to a throttling flowmeter capable of facilitating replacement of a throttling orifice plate.
背景技术Background Art
量计大批量使用于流体工程中的管道流体流量测量，常见的流量计有浮子流量计、孔板流量计，文丘管流量计等，板孔流量计是利用流体经过板孔时，流束集中收缩，因而在孔板两边产生压差，孔板两侧的压力经引压管导入压力变送器，压力变送器根据流动连续性原理和伯努利方程可以推导出压力差与流量之间的关系而求得流量。Meters are widely used in fluid engineering to measure pipeline fluid flow. Common flow meters include float flowmeter, orifice flowmeter, venturi flowmeter, etc. Orifice flowmeter uses the fact that when the fluid passes through the plate hole, the flow beam is concentrated and contracted, thereby generating a pressure difference on both sides of the orifice. The pressure on both sides of the orifice is introduced into the pressure transmitter through the pressure lead pipe. The pressure transmitter can deduce the relationship between the pressure difference and the flow rate based on the flow continuity principle and Bernoulli's equation to obtain the flow rate.
孔板流量计的特性决定了它具有流量准确稳定的优点，节流式流量计在长时间使用后，节流板孔上的节流孔会在水流的冲击力作用下发生一定的磨损，从而使节流孔逐渐变大，若不及时更换，会直接影响检测的精准度The characteristics of the orifice flowmeter determine that it has the advantages of accurate and stable flow. After a throttling flowmeter is used for a long time, the throttling hole on the throttling plate hole will be worn to a certain extent under the impact of the water flow, so that the throttling hole gradually becomes larger. If it is not replaced in time, it will directly affect the accuracy of the detection.
相关技术中，公开了一种焊接节流式流量计，包括流量计本体和流量计算机，所述流量计本体内部设有贯穿流量计本体的流体通道，所述流体通道内部可拆卸连接有节流孔板，所述流量计本体外侧开有与流体通道内部连通的更换窗，所述更换窗上设有与流体通道密封连接的盖板，所述流量计本体上设有与流体通道内部连通的引压管，所述引压管远离流量计本体的一端设有压力传感器，所述压力传感器与流量计算机电气连接，其节流孔板与流体通道可拆卸连接，且开有更换窗，可从侧面方便的更换节流孔板。In the related art, a welded throttling flowmeter is disclosed, including a flowmeter body and a flow computer, wherein the flowmeter body is provided with a fluid channel running through the flowmeter body, a throttling orifice plate is detachably connected to the inside of the fluid channel, a replacement window is provided on the outside of the flowmeter body and connected to the inside of the fluid channel, a cover plate is provided on the replacement window and sealed with the fluid channel, a pressure lead pipe is provided on the flowmeter body and connected to the inside of the fluid channel, a pressure sensor is provided at one end of the pressure lead pipe away from the flowmeter body, the pressure sensor is electrically connected to the flow computer, the throttling orifice plate is detachably connected to the fluid channel, and a replacement window is provided, so that the throttling orifice plate can be conveniently replaced from the side.
但是，上述结构中还存在不足之处，其装置在使用时，其在对节流板孔进行更换时，需要将流量计前端的阀门关闭，否则更换时会泄露大量液体，会影响管道的正常输送工作。However, there are still some shortcomings in the above structure. When the device is in use, when replacing the throttle plate hole, the valve at the front end of the flow meter needs to be closed, otherwise a large amount of liquid will leak during the replacement, which will affect the normal transportation work of the pipeline.
因此，有必要提供一种新的能够便于更换节流孔板的节流式流量计解决上述技术问题。Therefore, it is necessary to provide a new throttling flowmeter that can easily replace the throttling orifice plate to solve the above technical problems.

通过设置外密封垫和内密封垫，使得能够在对第一节流孔板21和第二节流孔板22更换后，对密封板8和侧挡板9移动后与管体1接触处的密封性，避免液体泄露。By providing an outer sealing gasket and an inner sealing gasket, after the first throttling orifice plate 21 and the second throttling orifice plate 22 are replaced, the sealing plate 8 and the side baffle plate 9 can be moved to improve the sealing of the contact point with the tube body 1 to avoid liquid leakage.
如图7所示，所述安装壳13内固定安装有两个固定板，所述传动轴14贯穿两个固定板并与固定板转动连接；As shown in FIG. 7 , two fixing plates are fixedly installed in the mounting shell 13 , and the transmission shaft 14 passes through the two fixing plates and is rotatably connected to the fixing plates;
通过设置固定板，使得能够对传动轴14进行限制，使传动轴14能够平稳的转动，避免其晃动。By providing the fixing plate, the transmission shaft 14 can be restricted so that the transmission shaft 14 can rotate smoothly and avoid shaking.
如图5所示，所述第一节流孔板21和第二节流孔板22上均固定安装有环形密封垫，所述环形密封垫与安装槽20的内壁相接触；As shown in FIG5 , an annular sealing gasket is fixedly mounted on the first throttling orifice plate 21 and the second throttling orifice plate 22 , and the annular sealing gasket is in contact with the inner wall of the mounting groove 20 ;
通过设置环形密封垫，使得能够提高第一节流孔板21和第二节流孔板22与条形滑块7之间的密封性，避免液体通过第一节流孔板21和第二节流孔板22与条形滑块7之间缝隙流过，导致计量不准确。By providing an annular sealing gasket, the sealing between the first throttling orifice plate 21 and the second throttling orifice plate 22 and the strip slider 7 can be improved to prevent liquid from flowing through the gap between the first throttling orifice plate 21 and the second throttling orifice plate 22 and the strip slider 7, resulting in inaccurate metering.
本发明提供的能够便于更换节流孔板的节流式流量计的工作原理如下：The working principle of the throttling flowmeter provided by the present invention, which can facilitate the replacement of the throttling orifice plate, is as follows:
当需要对第二节流孔板22进行更换时，将所需第一节流孔板21通过内六角螺栓固定在外侧的安装槽20内，通过转动手轮19带动固定轴18和第四锥形齿轮17转动，第四锥形齿轮17带动第三锥形齿轮16、传动轴14和两个第二锥形齿轮15转动，第二锥形齿轮15带动第一锥形齿轮12和螺纹杆11转动，在两个内螺纹块10的作用下，条形滑块7在管体1上滑动，同时密封板8在孔板槽6内滑动，直至第一节流孔板21移动至孔板槽6内，第二节流孔板22移动至管体1外，完成对节流板孔的更换同时在外密封垫和内密封垫的作用下，可以避免液体泄露，此时将第二节流孔板22上的内六角螺栓拆下，即可将第二节流孔板22拆下。When it is necessary to replace the second throttling orifice 22, the required first throttling orifice 21 is fixed in the outer mounting groove 20 by the hexagon socket bolts, and the fixed shaft 18 and the fourth bevel gear 17 are driven to rotate by turning the hand wheel 19, and the fourth bevel gear 17 drives the third bevel gear 16, the transmission shaft 14 and the two second bevel gears 15 to rotate, and the second bevel gear 15 drives the first bevel gear 12 and the threaded rod 11 to rotate. Under the action of the two internal thread blocks 10, the strip slider 7 slides on the tube body 1, and the sealing plate 8 slides in the orifice groove 6 until the first throttling orifice 21 moves into the orifice groove 6, and the second throttling orifice 22 moves to the outside of the tube body 1, completing the replacement of the throttling plate hole. At the same time, under the action of the outer sealing gasket and the inner sealing gasket, liquid leakage can be avoided. At this time, the hexagon socket bolts on the second throttling orifice 22 are removed, and the second throttling orifice 22 can be removed.
