The invention provides a control water valve convenient to replace. The control water valve convenient to replace comprises a valve base; first connection rods are hinged to the two sides of the top of the valve base through rotary shafts; a hollow pipe is fixedly installed on one side of the outer surface of each first connection rod; a connection spring is fixedly installed on one side of the inner wall of each hollow pipe; one end of each connection spring is fixedly connected with a limiting block; one side of each limiting block is fixedly provided with a fixing rod; pulling rods are welded to the upper and lower sides of each fixing rod; L-shaped rods are fixedly installed on the two sides of the outer surface of the valve base; concave boards are fixedly installed on one sides of the outer surfaces of the L-shaped rods; and one sides of the concave boards are connected with one ends of the fixing rods through formed clamping grooves in a clamped mode. According to the control water valve convenient to replace, through arrangement of the connection springs, clamped connection and fixation of the fixing rods and the concave boards on the L-shaped rods are convenient, then dismounting of a supporting rod and the first connection rods is convenient, the dismounting mode is simpler, dismounting operation can be finished only by one person, and then labor is saved.
