自力式调节阀需要改进的几个方面

来源:http://www.jnlgvf.com/ 日期:2022-03-28 发布人:guanli
因为自力式调节阀无需外力作用,方便快捷,所以很多业内人士都认为自力式调节阀会成为调节阀里面更具发展前景的调节阀产品。有鉴于此,现在很多的调节阀厂家都对自力式调节阀投入了更多的资金进行生产。但是作为调节阀市场上的年轻产品,自力式调节阀还有一些技术上问题需要我们慢慢解决,今天我们就来讲讲自力式调节阀还需要解决哪些技术上的问题。
Because the self-contained regulating valve does not need external force, it is convenient and quick, so many people in the industry believe that self-propelled regulating valve will become a more promising regulator valve product in the regulating valve. In view of this, many control valve manufacturers have invested more money in the production of self operated control valves. However, as a young product in the regulating valve market, there are still some technical problems that need to be solved slowly. Today, let's talk about the technical problems that need to be solved.
简述自力式调节阀需要改进的三个方面
This paper briefly describes three aspects of self operated regulating valve that need to be improved
1、调节精度。自力式调节阀是由机械的方法组成的纯比例调节系统,不可避免的存在偏差。因此它的适用范围只能是对于调节精度要求不高的场合。目前,已经有很多的自力式调节阀厂家开始通过在机械加工和材料选择等等方面的努力,希望能改进自力式调节阀的调节精度。
1. Adjustment accuracy. Self operated regulating valve is a pure proportional regulating system composed of mechanical methods, which inevitably has deviation. Therefore, its scope of application can only be used in occasions where the adjustment accuracy is not high. At present, many self operated regulating valve manufacturers have begun to improve the regulation accuracy of self operated regulating valve through their efforts in machining and material selection.
2、允许的压差较普通调节阀要小,口径也受限制。这是由自力式调节阀的工作原理所决定的。自力式调节阀口径能做到DN250,这对于大部分场合是够用的,如果在一些特殊场合,只能使用两台或多台并联。
2. The allowable differential pressure is smaller than that of ordinary regulating valve, and the caliber is also limited. This is determined by the working principle of the self operated regulating valve. The diameter of self operated regulating valve can reach DN250, which is enough for most occasions. In some special occasions, only two or more sets can be used in parallel.
3、由于自力式调节阀的工作原理和结构特点,导致它对介质黏度的要求特别高。因为介质黏度过高容易引起引压管的堵塞,影响膜片的弹性,导致阀内压力平衡元件不能正常工作。目前自力式调节阀厂家只能通过推荐介质允许黏度的值,来避免客户出现上述情况。
3. Due to the working principle and structural characteristics of self operated regulating valve, it has particularly high requirements for medium viscosity. Because the medium viscosity is too high, it is easy to cause the blockage of the impulse pipe and affect the elasticity of the diaphragm, resulting in the failure of the pressure balance element in the valve to work normally. At present, the manufacturers of self operated regulating valve can only recommend the allowable viscosity of the medium to avoid the above situation.
这是目前自力式调节阀需要解决的主要的三个技术问题,相信广大技术人员的努力之下,一定能够克服上面的问题,使自力式调节阀获得更大的发
These are the three main technical problems that need to be solved for the self operated regulating valve at present. I believe that with the efforts of the majority of technicians, we will be able to overcome the above problems and make the self operated regulating valve achieve greater development
