The utility model relates to a balance valve, which comprises a valve cover, a valve stem and a valve body. The valve cover is connected with the valve body, and the valve stem is arranged in the inner part of the valve cover and the valve body. The valve cover shaft sleeve is arranged between the end of the valve stem inserted into the valve cover and the valve cover, and the valve cover and the valve body are perforated at the middle part of the valve stem and at the interface between the valve cover and the valve body. The diaphragm gasket is provided with a spring between the shaft sleeve of the valve cover and the diaphragm gasket, and a pressure measuring valve is installed at the upper part of the valve body wall at the inlet and outlet end of the valve body. In addition, the end of the valve stem inserted into the valve cover is connected with the controller through a connecting rod. The utility model adds a group of springs between the shaft sleeve of the valve cover and the diaphragm gasket to enable the valve to function as a stop valve within a certain pressure range; at the same time, pressure measuring valves are installed at the inlet and outlet ends of the valve body, and controllers are installed on the valve stem, and pressure values at the inlet and outlet ends of the valve are fed back to the control on the valve stem through the pressure measuring valve. The device adjusts the opening of the spool and the valve seat to play the function of regulating valve.
【技术实现步骤摘要】
一种平衡阀
本技术涉及一种阀门,具体涉及一种性能更加多样化的平衡阀。
技术介绍
平衡阀是在水力工况条件下,起到调节静态、动态平衡的阀门。以往传统的平衡阀一直致力于在调节平衡的性能上有所改善,却往往忽视了平衡阀本身的结构特性,以致于不能够将其平衡阀的全部功能发挥出来。
技术实现思路
鉴于此,本技术的目的在于,提供一种性能更加多样化的平衡阀,旨在通过对传统平衡阀结构的改进来克服以往平衡阀性能单一的缺陷。为了达到上述技术目的,采取的技术方案如下:一种平衡阀,包括阀盖、阀杆和阀体,所述阀盖与阀体相连接,所述阀杆设置在所述阀盖与阀体的内部,其中,插入至所述阀盖内部的阀杆的端部与所述阀盖之间设置有阀盖轴套,在所述阀杆的中部且位于所述阀盖与阀体的分界面处贯穿有隔膜垫片,在所述阀盖轴套与所述隔膜垫片之间设置有弹簧,同时在所述阀体的进出端的阀体壁上分部安装有测压阀,另外,插入至所述阀盖内部的阀杆的端部通过连接杆与控制器相连。较佳地,所述隔膜垫片的上方设置有安装在所述阀杆上的阀杆螺母。更佳地,所述隔膜垫片与所述阀杆螺母之间设置有弹簧垫圈。更佳地,所述隔膜垫片上还设置有一弹簧垫片,该弹簧垫片的两端设置有一凸起部,该凸起部与所述弹簧垫圈之间留有间隙。更佳地,所述弹簧的一端置于所述阀盖轴套的外部并固定在所述阀盖的阀盖壁上,另一端固定在所述弹簧垫片凸起部与所述弹簧垫圈之间的间隙内。本技术的有益效果:本技术通过在阀盖轴套和隔膜垫片之间增加一组弹簧,使阀门能够在一定的压力范围内起到截止阀的功能;同时在阀体进出端分别安装测压阀,在阀杆上安装控制器,通过测压阀将阀门进出端的压力值反馈给阀杆上的控 ...
