良工阀门是流体管道的控制装置。其基本功能是接通或切断管道中介质的流动,改变介质的流向,调节介质的压力和流量,并设置系统中的各种阀门,是实现管道输送的重要保证。管网和设备正常运行。那么,在生活中,我们应该如何操作和维护良工阀门呢?
Lianggong valve is a control device for fluid pipelines. Its basic function is to connect or cut off the flow of the medium in the pipeline, change the direction of the medium, regulate the pressure and flow of the medium, and set various valves in the system, which is an important guarantee for achieving pipeline transportation. The pipeline network and equipment are operating normally. So, how should we operate and maintain good valves in daily life?
阀门在运行过程中的保养原则如下:
The maintenance principles for valves during operation are as follows:
保持良工阀门外部和运动部件的清洁,保护阀门油漆的完整性。阀门表面、阀杆和阀杆螺母上的梯形螺纹、阀杆螺母与支架、齿轮、蜗轮等部件之间的滑动部位容易沉积大量灰尘、油、介质 残留物和其他污垢,导致阀门磨损和腐蚀。 因此,始终保持阀门清洁。一般刷阀门上的灰尘,用压缩空气吹,甚用铜丝刷,直到加工面和配合面呈现金属光泽,喷漆面呈现油漆的原色。捕集器应由人员每班检查一次; 定期打开冲洗阀和疏水阀底塞冲洗,或定期拆开冲洗,防止脏物堵塞阀门。
Keep the exterior and moving parts of the valve clean and protect the integrity of the valve paint. The trapezoidal threads on the valve surface, valve stem, and valve stem nut, as well as the sliding parts between the valve stem nut and brackets, gears, worm gears, and other components, are prone to accumulate a large amount of dust, oil, medium residue, and other dirt, leading to valve wear and corrosion. Therefore, always keep the valve clean. Generally, brush the dust on the valve with compressed air, or even use a copper wire brush, until the machined and mating surfaces present a metallic luster, and the painted surface presents the original color of the paint. The trap should be inspected by personnel once per shift; Regularly open the flushing valve and drain valve bottom plug for flushing, or regularly disassemble and flush to prevent dirt from blocking the valve.
为保持良工阀门的润滑,阀门的梯形螺纹、阀杆螺母与支架的滑动部位、轴承位置、齿轮与蜗轮的啮合部位等配合部位都需要良好的润滑 减少相互摩擦的条件,避免失相,对于运行中容易损坏或丢失的零件,如无油杯、注油嘴等,应设置润滑系统,并验证油路的情况。
To maintain the lubrication of well functioning valves, the trapezoidal threads of the valve, the sliding parts of the valve stem nut and bracket, the bearing position, and the meshing parts of the gear and worm gear all require good lubrication to reduce mutual friction and avoid phase loss. For parts that are easily damaged or lost during operation, such as oil cups, oil nozzles, etc., a lubrication system should be installed and the condition of the oil circuit should be verified.
润滑部位应根据具体情况定期加油。高温频繁开启的良工阀门,适合每周每月加油一次; 不经常打开且温度较低的阀门可能具有更长的加油周期。 润滑剂包括机油、黄油、二硫化钼和石墨。油对高温阀门不利; 黄油也不是,它们因高温熔化而丢失。该阀适用于高温添加二硫化钼和石墨粉。外露的润滑部位,如梯形螺纹和齿,如果使用黄油等润滑脂,容易沾染灰尘,而二硫化钼和石墨粉则不易沾染灰尘,润滑效果优于黄油。 石墨粉不易直接涂装,可加少许油或水调成糊状备用。
Lubricating parts should be regularly oiled according to specific conditions. A well functioning valve that frequently opens in high temperatures, suitable for refueling once a week to once a month; Valves that are not frequently opened and have lower temperatures may have longer refueling cycles. Lubricants include engine oil, butter, molybdenum disulfide, and graphite. Oil is detrimental to high-temperature valves; Butter is not either, they are lost due to high temperature melting. This valve is suitable for high-temperature addition of molybdenum disulfide and graphite powder. Exposed lubrication parts, such as trapezoidal threads and teeth, are prone to dust if grease such as butter is used, while molybdenum disulfide and graphite powder are less prone to dust and have better lubrication effects than butter. Graphite powder is not easy to apply directly, it can be mixed with a little oil or water to form a paste for later use.
密封旋塞阀应在规定时间上油,否则容易磨损和泄漏。
Sealed plug valves should be oiled within the specified time, otherwise they are prone to wear and leakage.
保持两件完好无损。法兰和支架的螺栓应充分拧紧,不得松动,如果手轮上的紧固螺母松动,应及时拧紧,以免接头磨损或手轮丢失。 手轮丢失后,不允许用疏水阀更换手轮,应及时更换,填料压差不允许偏转或没有预紧间隙。在容易被雨、雪、灰尘和其他污染物污染的环境中。阀杆应装有防护罩,阀门上的刻度应保持完好。阀门密封件、阀盖和气动附件应完好无损。 绝缘护套应无凹痕和裂缝。
Keep both items intact and undamaged. The bolts of the flange and bracket should be fully tightened and not loose. If the fastening nut on the handwheel is loose, it should be tightened in a timely manner to avoid joint wear or handwheel loss. After the handwheel is lost, it is not allowed to replace it with a drain valve. It should be replaced in a timely manner. The packing pressure difference should not deviate or there should be no pre tightening gap. In environments that are easily polluted by rain, snow, dust, and other pollutants. The valve stem should be equipped with a protective cover, and the scale on the valve should be kept intact. Valve seals, valve covers, and pneumatic accessories should be intact and undamaged. The insulation sheath should be free of dents and cracks.
此外,严禁敲击、支撑重物或站在良工阀门上,以免污染或损坏阀门。 禁止使用非金属网门和铸铁阀门。
In addition, it is strictly prohibited to strike, support heavy objects, or stand on good work valves to avoid contaminating or damaging the valves. Non metallic mesh doors and cast iron valves are prohibited from use.
