摘要: The invention relates to a well shutdown by one key. the key comprises pressure transmitters which are arranged on sleeve, vertical pipe and an electromagnetism proportional valve displacement sensor valve. connected with programmable automation controller (PAC), ADC module is in PAC, converts analog signals into digital transmit control center through wireless local area network (WLAN) RS422, tablet computer three-position four-way module. Due fact that valve, long-distance oil controlled coherent converted transmitted of WLAN RS422. can intuitively display values open real time, convenient dispatch test center.
