因?yàn)樽粤κ秸{(diào)節(jié)閥無需外力作用，方便快捷，所以很多業(yè)內(nèi)人士都認(rèn)為自力式調(diào)節(jié)閥會成為調(diào)節(jié)閥里面更具發(fā)展前景的調(diào)節(jié)閥產(chǎn)品。有鑒于此，現(xiàn)在很多的調(diào)節(jié)閥廠家都對自力式調(diào)節(jié)閥投入了更多的資金進(jìn)行生產(chǎn)。但是作為調(diào)節(jié)閥市場上的年輕產(chǎn)品，自力式調(diào)節(jié)閥還有一些技術(shù)上問題需要我們慢慢解決，今天我們就來講講自力式調(diào)節(jié)閥還需要解決哪些技術(shù)上的問題。
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.
簡述自力式調(diào)節(jié)閥需要改進(jìn)的三個(gè)方面
This paper briefly describes three aspects of self operated regulating valve that need to be improved
1、調(diào)節(jié)精度。自力式調(diào)節(jié)閥是由機(jī)械的方法組成的純比例調(diào)節(jié)系統(tǒng)，不可避免的存在偏差。因此它的適用范圍只能是對于調(diào)節(jié)精度要求不高的場合。目前，已經(jīng)有很多的自力式調(diào)節(jié)閥廠家開始通過在機(jī)械加工和材料選擇等等方面的努力，希望能改進(jìn)自力式調(diào)節(jié)閥的調(diào)節(jié)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、允許的壓差較普通調(diào)節(jié)閥要小，口徑也受限制。這是由自力式調(diào)節(jié)閥的工作原理所決定的。自力式調(diào)節(jié)閥口徑能做到DN250，這對于大部分場合是夠用的，如果在一些特殊場合，只能使用兩臺或多臺并聯(lián)。
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、由于自力式調(diào)節(jié)閥的工作原理和結(jié)構(gòu)特點(diǎn)，導(dǎo)致它對介質(zhì)黏度的要求特別高。因?yàn)榻橘|(zhì)黏度過高容易引起引壓管的堵塞，影響膜片的彈性，導(dǎo)致閥內(nèi)壓力平衡元件不能正常工作。目前自力式調(diào)節(jié)閥廠家只能通過推薦介質(zhì)允許黏度的值，來避免客戶出現(xiàn)上述情況。
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.
這是目前自力式調(diào)節(jié)閥需要解決的主要的三個(gè)技術(shù)問題，相信廣大技術(shù)人員的努力之下，一定能夠克服上面的問題，使自力式調(diào)節(jié)閥獲得更大的發(fā)
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
