Abstract

The invention discloses a valve opening control method and a valve closing control method of a meter valve. The valve opening control method and the valve closing control method of the meter valve solve the technical problem of unstable system power supply in the valve opening process in the prior art. In the valve opening control method of the meter valve, when a control unit controls an execution part to execute valve opening actions, the control unit outputs a valve opening drive signal by N times (N is a positive integer greater than 1), after receiving the valve opening drive signal, theexecution part executes the valve opening actions to enable a valve to reach the valve opening position state after N times of valve opening actions from the valve closing state. In the valve closingcontrol method of the meter valve, when the control unit controls the execution part to execute valve closing actions, the control unit outputs a valve closing drive signal by M times (M is a positiveinteger greater than 1), and the execution part executes the valve closing actions after receiving the valve closing drive signal so that the valve reaches the valve closing position state after M times of valve closing actions from the valve opening state.

Description

【Technical field】 [0001] The invention relates to the technical field of meter valve control, in particular to a meter valve opening control method and a valve closing control method. 【Background technique】 [0002] The meter valves in the prior art generally adopt a timing method when opening and closing the valve, so that the valve can complete the opening and closing of the valve at one time. In this way, due to the excessive movement of the valve, the valve will be opened and closed. The valve process consumes a large amount of electricity, which leads to unstable power supply of the entire system, resulting in improper opening and closing of the valve, resulting in poor sealing of the valve after closing, resulting in gas or liquid leakage. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a meter valve opening control method and valve closing control method, which c...
