The invention discloses a water conservancy control valve with adjustable opening pressure, which comprises a casing, a protective sleeve is arranged on the right side of the upper end of the casing, and a regulator is installed on one side of the protective sleeve, the regulator includes a casing, and the casing runs through the casing. To protect the side wall of the sleeve, slider 1 and slider 2 are respectively arranged on the left and right sides of the sleeve. There is a spring, and the side of the slider two far from the spring is connected with a screw through the bearing seat. The right end of the screw passes through the casing and is provided with a knob, and a threaded seat is provided between the screw and the side wall of the casing. The screw and the threaded seat Threaded connection, the outer side of the screw rod is located between the casing and the knob, and a fixed nut is sleeved, and the side of the slider one far away from the spring is provided with a pull rope. The invention can automatically adjust the rotation angle of the blocking block according to the water injection pressure, adjust the outlet water flow, and achieve the purpose of automatic adjustment according to the difference in water pressure, without manual operation, and is easy to use.
Description
Technical field [0001] The present invention relates to a control valve technical field, in particular an adjustable opening pressure water control valve. Background technique [0002] Is the flow rate of the valve controlling flow of the fluid medium, flow, pressure, temperature and other mechanical means, the valve is substantially in the piping system components. Valve tube pump in the art and as often as a separate category discussed. Adjustable opening pressure water control valves is pressure controlled valve, the pipe should generally be installed horizontally. [0003] Prior art adjustable opening pressure of the water control valves normally open valve body by manual, inconvenient operation, automatic control valves can not automatically adjust the pressure depending on the pressure. Thus, those skilled in the art to provide an adjustable opening pressure water control valves, in order to solve the problems raised in the background art. Inventive content [0004] Object...
