Description
本創作係有關一種流體壓力調整裝置，特別是指一種藉由系統控制單元對於壓力調整器之供氣、排氣控制，調節流體輸出端壓力之流體壓力調整裝置。The present invention relates to a fluid pressure adjusting device, and more particularly to a fluid pressure adjusting device for adjusting the pressure at the fluid output end by the system control unit for supplying air and exhaust to the pressure regulator.
迄今以來，空壓系統在自動化設備領域中的運用，無論在高科技電子業、半導體業、醫療設備、石化工業或是航天工業等，都扮演著不可或缺的角色，而運用於保持氣壓源輸出壓力值的壓力調節器，更是空壓系統當中極為重要的零組件之一。So far, the use of air compressor systems in the field of automation equipment plays an indispensable role in high-tech electronics, semiconductor industry, medical equipment, petrochemical industry or aerospace industry, and is used to maintain air pressure. The pressure regulator that outputs the pressure value is one of the most important components in the air compressor system.
壓力調整器之以往技術，曾揭示在例如中華民國專利公報349191，然而在上述之以往技術的空氣壓力調整器中，除供開閉供氣口的供氣閥體(主閥)及其彈簧之外、還需要結合排氣閥體及其彈簧，以及在第一隔膜室(pilot室)與輸出口之間還須設置第二隔膜室並經由閥桿的空隙將輸出口的壓力傳達至第二隔膜室，然後再藉由第一、第二隔膜室之間的壓差以移動閥桿，閥桿再啟閉主閥與排氣閥；因此其構造過於複雜、成本較高。The prior art of the pressure regulator has been disclosed, for example, in the Republic of China Patent Publication No. 349191. However, in the above-described prior art air pressure regulator, in addition to the air supply valve body (main valve) for opening and closing the air supply port and its spring It is also necessary to combine the exhaust valve body and its spring, and a second diaphragm chamber between the first diaphragm chamber and the output port, and transmit the pressure of the output port to the second diaphragm via the gap of the valve stem The chamber then moves the valve stem by the pressure difference between the first and second diaphragm chambers, and the valve stem reopens the main valve and the exhaust valve; therefore, the structure is too complicated and costly.
再者：出氣口的壓力必需經由閥桿的空隙傳達至第二隔膜室、這就造成了時間上的延遲，閥桿及主閥的移動自然也就出現了延遲的現象，使得出氣口的壓力穩定性不佳，尤其是流量經常在短時間內大幅變化的運用場合、此現象特別明 顯。Furthermore, the pressure of the air outlet must be transmitted to the second diaphragm chamber through the gap of the valve stem, which causes a delay in time, and the movement of the valve stem and the main valve naturally causes a delay, so that the pressure of the air outlet Poor stability, especially in applications where the flow rate often changes greatly in a short period of time. This phenomenon is particularly clear. Obvious.
再者：以往技術中、第一隔膜室(pilot室)其增壓與減壓的時機，是由連接到出氣口的壓力檢知器、比對出氣口的實際壓力值與設定值之後，再動態的決定要做增壓或減壓的動作。然而這樣的運作系統、在使用的流量為定值或緩慢變化的場合下、的確是能將出氣口的壓力穩定在所設定的壓力值，但是當使用在流量會急遽變化的場合時，經常會造成出口的壓力產生震盪的現象。Furthermore, in the prior art, the timing of the pressure increase and decompression of the first diaphragm chamber (pilot chamber) is determined by the pressure detector connected to the air outlet and the actual pressure value and the set value of the air outlet. Dynamically decide to do the boost or decompression action. However, in such an operating system, when the flow rate used is constant or changes slowly, it is indeed possible to stabilize the pressure of the air outlet at the set pressure value, but when used in a situation where the flow rate will change rapidly, it is often The pressure on the export caused a shock.
例如當使用的流量突然增加時、出氣口的壓力會突然下降，此時壓力感知器會偵測到壓力下降，控制系統比對設定值後，決定增加第一隔膜室的壓力，但是其實這個調整是錯誤的，結果造成了第一隔膜室的壓力過大，使得主閥開啟過大進而導致壓力過大，接著控制系統偵測到壓力上升、比對設定值後就開始減少第一隔膜室的壓力，結果形成了一小段時間的震盪現象。For example, when the flow rate used suddenly increases, the pressure at the air outlet will suddenly drop. At this time, the pressure sensor will detect the pressure drop. After the control system compares the set value, it decides to increase the pressure of the first diaphragm chamber, but in fact, this adjustment It is wrong. As a result, the pressure in the first diaphragm chamber is too large, so that the main valve is opened too much and the pressure is too large. Then the control system detects the pressure rise and compares the set value to start reducing the pressure of the first diaphragm chamber. Formed a small period of shock.
有鑑於此，本創作即在提供一當使用在流量會急遽變化的場合時，仍可快速的穩定流體輸出壓力之流體壓力調整裝置，為其主要目的者。In view of this, the present invention provides a fluid pressure adjusting device which can quickly stabilize the fluid output pressure when the flow rate is rapidly changed, and is the main purpose.
