Scope

Main technical content: When the valve flap and valve seat of the indoor fire hydrant come into contact with each other, the valve body is closed. Then, the outlet pipe is clamped on. The fourth straight rod on the outlet pipe comes into contact with the fifth straight rod, and the fifth straight rod drives the trapezoidal slider to move to the left. Under the resilience of the third spring, the third straight rod moves upward along its inclined surface relative to the trapezoidal slider. The third straight rod separates from the first straight rod, and at this time, the handwheel can be freely rotated to separate the valve flap from the valve seat and achieve water discharge. When the outlet pipe is pulled out, the fourth straight rod separates from the fifth straight rod. Under the resilience of the first spring, the fifth straight rod drives the trapezoidal slider to move to the right. The inclined surface of the trapezoidal slider presses against the third straight rod, and the third straight rod re-engages with the first straight rod to fix the valve flap and prevent accidental contact with the handwheel, wasting water resources. In this case, the valve can only be unlocked and opened when the fifth straight rod is pressed, thereby enhancing the safety of use.
