Description
技术领域：Technical field:
本实用新型涉及化工设备领域，具体是一种給水调节阀。The utility model relates to the field of chemical equipment, in particular to a water supply regulating valve.
背景技术：Background technique:
給水泵在运行时出口压力达到20Mpa以上，所以锅炉无法承受如此高的压力，故需要用給水调节阀来降压调节。目前市场上所出现的給水调节阀，由于材料及结构的不同，产品的性能差异很大。目前使用的給水调节阀以闸阀的形式存在，只能实现阀芯与阀座一次降压，降压程度低，同时各部位零件之间仅用螺栓、螺母连接，密封效果不好，同时容易脱落。When the feed water pump is running, the outlet pressure reaches above 20Mpa, so the boiler cannot withstand such a high pressure, so it is necessary to use a feed water regulating valve to reduce the pressure. Due to the difference in materials and structures, the performance of the water supply regulating valves appearing on the market varies greatly. The currently used water supply regulating valve exists in the form of a gate valve, which can only realize one-time pressure reduction of the valve core and valve seat, and the degree of pressure reduction is low. At the same time, only bolts and nuts are used to connect the parts of each part, the sealing effect is not good, and it is easy to fall off. .
实用新型内容：Utility model content:
本实用新型所要解决的技术问题在于克服现有技术的缺陷，提供一种效果更好的給水调节阀。The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a water supply regulating valve with better effect.
本实用新型所要解决的技术问题采用以下的技术方案来实现：The technical problem to be solved by the utility model adopts the following technical solutions to realize:
