Abstract: The present disclosure provides a suction pressure regulating valve and a parallel compressor system. The suction pressure regulating valve includes a valve body having a suction channel for communicating with a suction port of a compressor; a valve core disposed in the valve body and allowed to extend into and retract from the suction channel to change a flow area of the suction channel; and a rotating member rotatably connected to the valve body and cooperating with the valve core, wherein the rotating member is configured to rotate relative to the valve body so as to drive the valve core to extend into and retract from the suction channel. In this way, by using the suction pressure regulating valve, real-time regulation may be made according to different working conditions or flows, which may allow the compressor to achieve a good pressure equalization effect under various working conditions without repeated disassembly and assembly of pipelines for debugging, and to have superior reliability and safety.

The suction pressure regulating valve includes: a valve body having a suction channel for communicating with a suction port of a compressor; a valve core disposed in the valve body and allowed to extend into and retract from the suction channel to change a flow area of the suction channel; and a driving structure disposed between the valve body and the valve core, wherein the valve core is caused to extend into the suction channel in a case that the driving structure is in a first state, and the valve core is caused to retract from the suction channel in a case that the driving structure is in a second state.

Abstract: The disclosure discloses a mounting member including two support rails extending side by side. The two support rails include a first section and a second section in an extension direction thereof. The first section is adapted to carry a device with a first size, and the second section is adapted to carry a device with a second size. Grooves are provided on a top surface of the support rails so as to avoid interference between the bottom surface of the device and the top surface of the support rails. The disclosure also discloses a device assembly including a plurality of devices and the mounting member. The mounting member of the present disclosure allows the plurality of devices to be directly mounted on the two support rails without the need of additional support rails or spacers, thereby reducing the number of parts and improving the integrity and ease of installation of the device assembly.

Abstract: An explosives detonator system includes a detonator housing within which is provided a detonation circuit that includes a conductive pathway having a fuse head integrated therewith such that the conductive pathway passes along both electrodes and a resistive bridge of the fuse head. An uncharged chargeable voltage source is also integrated with the detonation circuit and is electrically sensitive to a charging property which is included in a charging signal. Exposure to the charging property charges the voltage source, thereby rendering it capable of generating a potential difference between the electrodes at least to equal the breakdown voltage of the resistive bridge. The charging property is any one or more of a charging light pulse, a charging temperature, a charging pressure and a charging radio frequency.

Abstract: An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a radio frequency identification (RFID) based switching device that detects a switching property of a radio switching signal that is transmitted to the detonator system and switches the initiating device, on detection of the detonation initiating property, to a standby condition in which the initiating device is capable of operatively accepting the detonation initiating signal when it is transmitted thereto.
