The utility model discloses a suction type double-gas analysis leak detector which comprises a first gas analysis chamber and a second gas analysis chamber which are independently arranged, the gas outlet end of the first gas analysis chamber and the gas outlet end of the second gas analysis chamber are connected with a vacuum pump, a first gas conveying pipe is connected to a first gas inlet of the first gas analysis chamber, and a second gas conveying pipe is connected to a second gas inlet of the second gas analysis chamber. A gas inlet II of the gas analysis chamber II is connected with a gas conveying pipe II, and a gas suction nozzle II and a gas suction nozzle I are respectively arranged on the gas conveying pipe II and the gas conveying pipe I in a front-back manner. When the concentrations of the gases sucked by the second suction nozzle and the first suction nozzle are consistent or basically close, the alarm signal is not sent out, and when the concentration of the gases sucked by the second suction nozzle at the front end is larger than that of the gases sucked by the first suction nozzle, the alarm signal of detecting a leakage point is sent out, namely, the gas leakage point exists near the second suction nozzle. And therefore, the position of the leakage point can be locked quickly, accurately and efficiently, and the leakage detection efficiency of the equipment can be greatly improved.

The utility model relates to the technical field of gas monitoring, and discloses a pumping type combustible gas alarm monitor which comprises a protective shell, the bottom of the inner wall of the protective shell is fixedly connected with a monitor body, and the right end of the protective shell is fixedly connected with a buzzer alarm. The detection position is extended through the extension pipe, a wider area can be covered, the getter pump is started, the getter pump sucks gas in the environment through the extension pipe and the exhaust pipe, then the gas is conveyed into the monitor body through the gas outlet pipe, the sucked gas is monitored through the monitor body, and the monitoring precision is improved. The detected gas is exhausted to the outside of the protective shell through the exhaust pipe, and when the monitor body detects that the concentration of the combustible gas exceeds a set safety threshold value, the buzzer alarm is triggered to give an alarm to remind field personnel to pay attention to safety and take corresponding measures, so that the safety in use is improved.

The filtering device includes an upper positioning cover and a hollow lower positioning frame; a filter cloth is assembled between the lower positioning frame and the upper positioning cover, and a through hole is formed on the upper positioning cover. This invention has a simple structure and ingenious design. Through the filtering mechanism, the filtering area is increased and the filtering effect is improved.

To provide a compression system that reduces the gas pressure in a gas pipe and lowers the temperature of the gas being pumped to other gas pipes without improving the cooling capacity of the cooling device. [Solution] The compression system according to this embodiment comprises a compressor, a cooling device, and a control unit. The intake side of the compressor is connected to a sealed pipe to be drawn in. The exhaust side of the compressor is connected to a pipe to be supplied. The compressor can draw gas from the pipe to be drawn in and reduce the pressure of the gas in the pipe to be drawn in to a predetermined pressure. The compressor can compress the drawn-in gas to a pressure higher than the pressure of the gas in the pipe to be supplied and supply it to the pipe to be supplied. The cooling device can cool the gas supplied from the compressor to the pipe to be supplied. The control unit operates the compressor at a constant reference rotational speed to supply gas from the compressor to the pipe to be supplied. If the temperature of the gas cooled by the cooling device exceeds a threshold below the allowable temperature of the pipe to be supplied, the control unit lowers the rotational speed of the compressor to a lower than the reference rotational speed.

One embodiment of the ventilation device according to the present disclosure comprises a protective housing that encloses at least a portion of a refrigerant circuit through which a refrigerant circulates, an intake port for taking in outside air into the protective housing, an exhaust port for discharging gas from the inside of the protective housing, and a fan that generates an airflow that passes from the intake port through the inside of the protective housing and is exhausted from the exhaust port, wherein the exhaust direction at the exhaust port is different from the intake direction at the intake port, and the arrangement of the exhaust port is optimized according to the wind velocity U of the gas drawn in from the exhaust port and the density ρ1 of the refrigerant gas.

A medium conveyance device includes a guide part that guides a medium being conveyed, a detector that is disposed to face the guide part, and a flow path forming portion that forms a flow space in which a gas can flow between the guide part and the flow path forming portion. The flow space is a space in which the gas taken in from a ventilation portion reaches an exhaust portion via the detector, and a flow velocity of the gas at the detector in the flow space is equal to or larger than a flow velocity of the gas at the ventilation portion.

The invention discloses a microbubble generation switching device, and belongs to the field of pipeline joints. Comprising a shell; a plurality of water flow channels arranged in parallel and an annular air inlet cavity arranged around the peripheries of the water flow channels are arranged in the shell; the side wall of the shell is further provided with an air inlet connector. The plurality of water flow channels are provided with lower reducing sections of which the sections are gradually reduced along the water flow direction; and a plurality of air inlet branch holes are formed in the side wall of the lower reducing section. The device has the beneficial effects that the design that a plurality of independent water flow channels are connected in parallel is adopted, and the Venturi reducing structures in all the channels are combined, so that remarkable negative pressure areas can be generated at a plurality of point positions at the same time under conventional water pressure, and gas is efficiently sucked in through the carefully-arranged gas inlet branch holes. The sucked gas is synchronously sheared and crushed by multi-channel high-speed water flow, and the gas-liquid contact area in unit volume is obviously increased, so that bubbles which are large in quantity, fine in size and uniform in distribution are generated.
