進口流量調(diào)節(jié)閥用心制造成就品質(zhì)德國洛克造

一、進口流量調(diào)節(jié)閥產(chǎn)品描述：

德國LOCKE洛克進口流量調(diào)節(jié)閥是一個新的調(diào)節(jié)閥種類，相對于手動調(diào)節(jié)閥，它的優(yōu)點是能夠自動調(diào)節(jié)相對于電動調(diào)節(jié)閥，它的優(yōu)點是不需要外部動力，應用實踐證明，在閉式水循環(huán)系統(tǒng)。(如熱水供暖系統(tǒng)，空調(diào)冷凍系統(tǒng))中，正確使用這種閥門，可以很方便地實現(xiàn)系統(tǒng)的流量分配，可以實現(xiàn)系統(tǒng)的動態(tài)平衡；可以大大簡化系統(tǒng)的調(diào)試工作；可以穩(wěn)定泵的工作狀態(tài)等。因此自力式調(diào)節(jié)閥在供熱空調(diào)工程中有著廣闊的應用前景。進口自力式流量調(diào)節(jié)閥的作用是在閥的進出口壓差變化的情況下，維持通過閥門的流量恒定，從而維持與之串聯(lián)的被控對象(如一個環(huán)路，一個用戶，一臺設備等，下同)的流量恒定，自力式流量控制閥的名稱較多，如自力式流量平衡閥，定流量閥，自平衡閥，動態(tài)流量平衡閥等，各種類型的自力式流量控制閥，結(jié)構(gòu)各有相異，但工作原理相似，“被評為歐美最認可的閥門之一 ”。

German locke imported flow control valve is a new type of control valve. Compared with manual control valve, its advantage is that it can automatically adjust. Compared with electric control valve, its advantage is that it does not need external power. Application practice has proved that it can be used in closed water circulation system. In the hot water heating system, air conditioning and refrigeration system, the correct use of this valve can easily realize the flow distribution of the system, realize the dynamic balance of the system, greatly simplify the debugging work of the system, and stabilize the working state of the pump. Therefore, self operated control valve has a broad application prospect in heating and air conditioning engineering. The function of the imported self operated flow control valve is to maintain the constant flow through the valve when the pressure difference between the inlet and outlet of the valve changes, so as to maintain the constant flow of the controlled object connected in series (such as a loop, a user, a device, etc., the same below). There are many names of self operated flow control valves, such as self operated flow balance valve, constant flow valve, self balance valve and dynamic state Various types of self operated flow control valves, such as flow balance valve, have different structures, but similar working principles. "It is rated as one of the most recognized valves in Europe and America".
