Abstract

PURPOSE: Apparatus for controlling accurately a flow rate of fluid of high pressure and high capacity using the combination of orifices is provided to reduce manufacturing costs and an installation costs by using a PLC(Programmable Logic Controller) and a solenoid valve instead of using a high-priced a pressure regulator and a high-priced flow control valve. CONSTITUTION: A flow rate of the fluid having the high pressure and the high capacity is controlled by using a multi-stepped orifice and a pressure sensor. The pressure sensor is used for sensing a pressure of an outlet of the exhaust tube. In a method for controlling the flow rate, the multi-stepped orifice is sequentially opened or shut by using a PLC or a computer program for performing an automatic pressure control operation.

Description

오리피스 조합을 이용한 고압 대 용량 유체의 정밀 압력제어{A precise pressure control system for high pressure and high capacity flow by combination of orifices}A precise pressure control system for high pressure and high capacity flow by combination of orifices

본 특허내용은 고압 대용량 조건에서의 압력제어를 통한 유량제어 시스템이다. 과거에는 Pressure regulator 또는 Flow control valve로 제어하였으나 제어 압력이 높고 유량이 큰 경우는 이에 맞는 현존하는 사양의 regulator를 구입하기 어려우며, 주문생산 시 고가이고 또한 수출허가 품목으로 수입이 어렵다.The present patent is a flow control system through pressure control under high pressure and large capacity conditions. In the past, it was controlled by a pressure regulator or a flow control valve, but when the control pressure is high and the flow rate is large, it is difficult to purchase an existing specification regulator that is suitable for this.

본 특허품은 기술적으로 제작하기 어렵고 구입이 어려웠던 pressure regulator, Flow control valve 없이 압력 제어를 하는 것이 특허가 이루고자 하는 기술적 과제인 것이다.It is a technical task of the patent to achieve pressure control without a pressure regulator and a flow control valve, which are technically difficult to purchase and difficult to purchase.

도 1은 본 특허에 의한 orifice 조합을 이용한 고압 대 용량 유체의 정밀 압력제어의 전체 상세도.1 is an overall detailed view of precise pressure control of a high pressure to capacity fluid using an orifice combination according to the present patent.

A : 고압 탱크, PRV: 레귤레이터, SV : 솔레노이드 밸브, PT : 압력센서A: high pressure tank, PRV: regulator, SV: solenoid valve, PT: pressure sensor

MV : manual valve, AV: automatic valve, CV : check valveMV: manual valve, AV: automatic valve, CV: check valve

도1 아래의 도 1 의 A101은 고압 탱크이다. PRV101은 고압 소용량 레귤레이터로 기준 값(기준 압력)을 고정한다. PT101 압력센서로부터 실시간으로 측정된 압력은 PLC를 통해 컴퓨터로 입력된다. 이는 PT103으로 측정된 압력과 비교하여 PLC를 통해 SV101-104와 SV105 솔레노이드 밸브를 작동시켜 RE-101의 압력을 제어하고자 하는 압력으로 맞춘다.A101 in FIG. 1 below FIG. 1 is a high pressure tank. The PRV101 is a high pressure, small capacity regulator that fixes a reference value (reference pressure). The pressure measured in real time from the PT101 pressure sensor is entered into the computer via the PLC. This compares the pressure measured by PT103 with the PLC to operate the SV101-104 and SV105 solenoid valves to adjust the pressure of the RE-101 to the desired pressure.

상기와 같은 목적을 달성하기 위하여, 본 특허는 PLC와 Solenoid valve 조합을 이용, orifice hole 크기를 기준 값에 따라 가공하여 시스템을 구성하므로 고정밀도의 제어(1% 오차)와 저비용으로 제작 설치 가능하다.In order to achieve the above object, the present patent uses a combination of PLC and solenoid valve, and processes the orifice hole size according to the reference value to configure the system, so it can be manufactured and installed with high precision control (1% error) and low cost. .

본 특허품은 설비 비용이 저렴하며 유지, 보수 및 향후 제어 압력 값이 바뀌더라도 orifice hole 크기만 교체하면 되므로 운용성 향상은 물론 경제적이다.The patented product is cheaper in equipment costs and improved in operability as well as economical because only the orifice hole size needs to be replaced even if the maintenance pressure is changed.
