Hydraulic drainage valve capable of reducing noise
The invention discloses a noise-reducing hydraulic drain valve which comprises a valve body, a valve core, a valve rod and a valve rod. The valve core is movably arranged on the valve body to open and close the water outlet; the hydraulic driving mechanism comprises a hydraulic cylinder arranged on the valve body, a piston arranged on the hydraulic cylinder in a sliding mode and a piston reset elastic piece used for resetting the piston, the piston and the valve element are in linkage fit, and a linkage idle stroke exists between the piston and the valve element; the piston overcomes the elastic force of the piston reset elastic piece to slide under the pressure of fluid entering the hydraulic cylinder so as to drive the valve element to open the water outlet. After the fluid pressure is relieved, the piston drives the valve element to move in the direction of closing the water outlet after sliding and linkage with the idle stroke under the action of the elastic force of the piston reset elastic piece, and after the piston is reset in place, the valve element continues to move by a preset distance relative to the piston and then is in sealing fit with the water outlet. Noise generated when the hydraulic drain valve is closed can be greatly reduced, meanwhile, the valve element is protected to a certain degree, the requirement for the assembly size is reduced, and the sealing effect of the valve element is ensured.
本发明公开了一种降噪的液压排水阀，包括：阀体，具有排水口；阀芯，活动设于阀体上以开闭排水口；液压驱动机构，包括设于阀体上的液压缸、滑动设于液压缸的活塞和用于对活塞进行复位的活塞复位弹性件，活塞与阀芯联动配合并且二者之间具有联动空行程；活塞在进入液压缸的流体压力下克服活塞复位弹性件的弹性力滑动从而带动阀芯打开排水口；流体压力泄压后，活塞在活塞复位弹性件的弹性力作用下滑动联动空行程后带动阀芯往关闭排水口的方向移动，活塞复位到位后，阀芯继续相对活塞活动预定距离后与排水口密封配合。本发明能够大大减小液压排水阀关闭时的噪音，同时对阀芯起到一定保护作用，降低对装配尺寸的要求，确保阀芯的密封效果。
