The invention belongs to hot equipment for
heat supply in the
building industry, and particularly relates to a controllable valve rod type valve for a
heat supply system. The lock body is fixedly arranged in a
pipe opening in the right side of the valve body, a lock cylinder is arranged in the lock body and located on the outer side of the valve rod, a lock body
chip, a lock
body contact and a
clutch mechanism are arranged in the lock cylinder, the
clutch mechanism is in linkage connection with two limiting columns, two pairs of limiting column grooves are formed in the positions, corresponding to the two limiting columns, of the valve rod, and a battery and a controller are further arranged in the unlocking body. Wherein the controller comprises a
communication unit, a
Bluetooth device, a storage unit, a control
chip, an identification unit and a
buzzer, and the controller communicates with the lock body
chip. The chip is additionally arranged in the lock body, the
clutch mechanism is controlled through a chip program of the lock body, so that opening and closing of the valve rod are controlled, control over fluid by the ball core can be systematically controlled, a
heat supply valve cannot be easily and mechanically opened, the control efficiency of a
heating system is improved, and loss of a heat source is reduced.
