Description
Technical field
The utility model relates to a kind of experimental apparatus manufacturing technology field, be specifically related to a kind of gas enter photosynthesis instrument before snubber assembly.
Background technology
When carrying out photosynthesis research, sometimes need control CO
2, O
2gas concentration etc., CO
2concentration controls generally there is supporting CO at present
2small steel cylinder, but O
2but do not have Deng other gases, as used low O
2(2%O
2) method is when measuring photorespiration rate, often can not coordinate other problems such as gas concentration, relative humidity well, cause determination data error comparatively large, or even damage the equipment such as photosynthesis instrument.
Utility model content
For the deficiencies in the prior art, the snubber assembly before the utility model provides a kind of gas to enter photosynthesis instrument.
To achieve these goals, the utility model solves the technical scheme that its technical matters adopts: a kind of gas enters the snubber assembly before photosynthesis instrument, comprise buffering bag, the side of buffering bag is provided with and cushions three-way connection that is that bag is connected and that communicate with bumping bag intracoelomic cavity, the opposite side being positioned at buffering bag is provided with the straight coupling be communicated with bumping bag intracoelomic cavity, water-inflow and drain valve is provided with at buffering bag top or bottom, the first passage mouth of three-way connection is connected with photosynthesis instrument by pipeline, the second channel mouth of three-way connection is communicated with air or closes, described straight coupling is saved bottle by output channel and gas and is connected.
A kind of gas that the utility model further provides enters the snubber assembly before photosynthesis instrument, and its three-way connection and straight coupling are plug-in type quick connector, and described draining valve is ball valve.
A kind of gas that the utility model further provides enters the snubber assembly before photosynthesis instrument, and its buffering bag is LDPE material, and described three-way connection, straight coupling, ball valve are PVC material.
The beneficial effects of the utility model: the utility model is when measuring special composition or specific proportions gas, preferably desired gas can stably be entered instrument for determining photosynthesis device, and the control be convenient to gas capacity and gas humidity and observation, reduce experimental system error, thus improve the degree of accuracy of experimental data.
Described photosynthesis instrument, concrete model is Li-6400.This instrument is with the most use in the world, more generally acknowledged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of gas as shown in Figure 1 enters the snubber assembly before photosynthesis instrument, comprise buffering bag 1, the side of buffering bag 1 is provided with and cushions three-way connection 2 that is that bag 1 is connected and that communicate with buffering bag 1 inner chamber, the opposite side being positioned at buffering bag 1 is provided with and the straight coupling 3 cushioning bag 1 inner space, water-inflow and drain valve 4 is provided with at buffering bag 1 top or bottom, the first passage mouth 5 of three-way connection 2 is connected with photosynthesis instrument 8 by pipeline, the second channel mouth 7 of three-way connection 2 is communicated with air or closes, described straight coupling 3 is saved bottle 6 by output channel and gas and is connected.
Inlet and outlet water all passes through bottom water-inflow and drain valve door 4, photosynthesis instrument 8 is connected to the first passage mouth 5 of three-way pipe, the second channel mouth 7 connecting air when using the gas of buffering bag 1 is closed, the second channel mouth being connected to buffering bag 1 when using gas in air is opened, and concrete opening/shutting mode can control with short flexible pipe and clip.
Described three-way connection 2 and straight coupling 3 are plug-in type quick connector, and described draining valve 4 is ball valve.
Described buffering bag 1 is LDPE material, is convenient to the gas content observed wherein, and namely inflatable bag body volume becomes large, and gas is taken out rear smaller volume by photosynthetic apparatus, and just not all right with hard material, described three-way connection 2, straight coupling 3, ball valve are PVC material.
When it should be noted that in addition owing to being measurement photosynthesis of plant, in gas, water vapour must be had simultaneously, and moisture can not be connected in venthole side, after the moisture of liquid directly enters photosynthesis instrument, can burn out the mainboard of photosynthesis instrument, can only be that the moisture input of gaseous state is just passable.
Claims (3)
1. a gas enters the snubber assembly before photosynthesis instrument, it is characterized in that comprising buffering bag, the side of buffering bag is provided with and cushions three-way connection that is that bag is connected and that communicate with bumping bag intracoelomic cavity, the opposite side being positioned at buffering bag is provided with the straight coupling be communicated with bumping bag intracoelomic cavity, water-inflow and drain valve is provided with at buffering bag top or bottom, the first passage mouth of three-way connection is connected with photosynthesis instrument by pipeline, the second channel mouth of three-way connection is communicated with air or closes, described straight coupling is saved bottle by output channel and gas and is connected.
2. a kind of gas according to claim 1 enters the snubber assembly before photosynthesis instrument, and it is characterized in that described three-way connection and straight coupling are plug-in type quick connector, described draining valve is ball valve.
3. a kind of gas according to claim 1 and 2 enters the snubber assembly before photosynthesis instrument, and it is characterized in that described buffering bag is LDPE material, described three-way connection, straight coupling, ball valve are PVC material.
