The invention relates to the technical field of an anti-hammer air valve, and discloses an anti-hammer air valve with a monitoring system. It includes a valve body and a valve cover, and a high-speed exhaust throttling device and a high-speed intake and exhaust device are installed inside. The anti-hammer air valve is equipped with a monitoring system. The monitoring system includes a power supply, a power supply control module, micro switches, various sensors, Communication module, central control module; by setting up the air valve monitoring device, the air valve on the pipeline or pipe network can be remotely monitored by the central control office for its different working states such as exhaust, suction, sealing, and failure. The control center displays the position of the faulty air valve and sends out an alarm, so that the management personnel can maintain and repair in time, save the labor of manual line inspection, prolong the service life of the air valve, and avoid the occurrence of malignant accidents such as water hammer, pipe burst and pipe collapse in the pipe network , which is conducive to improving smart water management.

The invention relates to a digital coiled tubing injection head. The digital coiled tubing injection head comprises a box body, hydraulic motors, a clamping block, a transition frame, and an adjustingmember, the two hydraulic motors are erected on one side of the box body, chain wheels are rotatably connected to the hydraulic motors, the clamping block is connected outside the chain wheels in a sleeving mode through a link chain, the transition frame is erected on one side of the top of the box body, the adjustment member is erected in the middle of the ring-shaped link chain, wherein the adjustment member comprises a threaded rod and a positioning pad, a support frame is fixedly connected into the box body, the threaded rod is connected to the support frame in a threaded mode, the positioning pad is rotatably connected to one end of the threaded rod, the end surface of the positioning pad is fixedly connected with a limiting plate, and the limiting plate abuts against the clamping block, so that the clamping block abuts against a coiled tubing; a pressure sensor is fixedly connected in the positioning pad, the pressure sensor abuts against the limiting plate, and the pressure sensor is electrically connected with a data terminal outside the box body. The digital coiled tubing injection head has the advantages that the working condition of an injection head is accurately judged and the injection head is ensured to be capable of working efficiently and stably.
