As further improvement of the utility model, pass through fastening handle between the sampling head lower casing and sampling head upper casing It is connected.
Correspond to as further improvement of the utility model, on the housing of the sampling head upper casing and divide gas to block and divide gas It is in partly up-small and down-big circular cone shape between sieve plate.
As further improvement of the utility model, the gas-tpe fitting of the sampling head lower casing and the axis of sampling head upper casing It is mutually perpendicular to.
It is of the present utility model to have technical effect that:The utility model product structure is simple, reasonable, and design concept is ingenious, can With the function of the pressure state microorganisms such as realization collection, while the function of gases at high pressure diffuser can also be realized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1, including sampling head upper casing 1, divide gas block 2, fastening handle 3, divide air sifter plate 4, culture dish support 5, sampling Head lower casing 6, safety valve 7, flow sensor 8, proportioning valve 9, gas outlet transfer block 10, gas outlet joint 11, pressure detecting interface 12nd, pressure-reducing valve 13, pressure sensor 14, magnetic valve 15, differential pressure pick-up 16, gas joint 17 through walls, T-shaped gas joint 18 etc..
As shown in figure 1, the utility model is a kind of bimodulus pressure reducer, including the sampling head lower casing 6 of interconnection and sampling Head upper casing 1, the top of sampling head lower casing 6 are provided with the culture dish support 5 for being used for fixing culture dish, and the top of sampling head upper casing 1 is set Put point gas and block 2, the bottom of sampling head upper casing 1, which is set, divides air sifter plate 4;The gas-tpe fitting of sampling head lower casing 6 is worn by pipeline connection Wall gas joint 17, the outlet side connecting T-shaped gas joint 18 of gas joint 17 through walls, T-shaped one end of gas joint 18 connect pressure sensor 14, other end connection safety valve 7, the air inlet of the gas outlet connection traffic sensor 8 of safety valve 7, the outlet of flow sensor 8 Mouth connection pressure-reducing valve 13, the air inlet of the gas outlet connection proportioning valve 9 of pressure-reducing valve 13, the gas outlet connection gas outlet of proportioning valve 9 Transfer block 10, gas outlet transfer block 10 are provided with pressure detecting interface 12, and pressure detecting interface 12 is connected to electromagnetism by flexible pipe The air inlet of valve 15, the gas outlet of magnetic valve 15 are connected with a detection mouth of differential pressure pick-up 16, differential pressure pick-up 16 Another detection mouth connects air, the gas outlet connection gas outlet joint 11 of gas outlet transfer block 10.
