The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The terms referred to in this application are explained first:
the duplex ball is a sampling tool for taking gas in the atmosphere; the sphere at one end of the duplex sphere close to the sampling tube is called a first sphere, and the sphere at one end of the duplex sphere close to the bladder is called a second sphere.
The tee is also called as a pipe tee or a tee pipe, a tee joint and the like. Mainly used for changing the direction of the fluid and is used at the position of a main pipeline and a branch pipeline.
The bladder is a soft and elastic rubber bag which is placed in the ball and inflated to make the ball elastic.
An embodiment of the present application provides an ordinary pressure sampling device for pesticide intermediate workshop, as shown in fig. 1, includes: sampling tube 1, pair ball 2 and ball 3, wherein, pair ball 2 is connected between sampling tube 1 and ball 3, and there is seal cover 4 at the junction of sampling tube 1 and pair ball 2, and the diameter of the one end that pair ball 2 is connected with sampling tube 1 is greater than the diameter of the one end that sampling tube 1 is connected with pair ball 2, and seal cover 4 is the cone shape, and the both ends of seal cover 4 all cup joint outside sampling tube 1 and pair ball 2.
And the sampling pipe 1 is used for guiding gas to be taken out from the reaction kettle or a pipeline and sent into a normal-pressure sampling device for a pesticide intermediate workshop.
And the duplex ball 2 is used for generating gas which is sucked into the reaction kettle or the pipeline through the sampling pipe 1 under negative pressure.
And the bladder 3 is used for storing the gas to be sampled, which is inhaled by the duplex ball 2.
When the sampling device is used, the duplex ball 2 is extruded to discharge gas in the duplex ball 2, the gas pressure in the duplex ball 2 is lower than the external gas pressure, and under the action of the gas pressure gradient force, the external gas pressure pushes the gas to be sampled in the reaction kettle or in the pipeline to enter the sampling tube 1 and further enter the duplex ball 2 and the ball bladder 3, so that the sampling without a gas pump under the normal pressure is realized. The application discloses a convenient degree when ordinary pressure sampling device for pesticide midbody workshop is through the transformation to pair ball 2, when having improved the airless pump in to reation kettle or the gas in the pipeline when carrying out the ordinary pressure sample.
In some embodiments, as shown in fig. 1, a tee 5 is further included, a first end of the tee 5 is connected to the duplex ball 2, a second end of the tee 5 is connected to the bladder 3, and a third end of the tee 5 is used for being connected to a gas detection device (not shown).
When the atmospheric pressure sampling device for the pesticide intermediate workshop is used for sampling gas, the third end of the tee joint 5 is in a blocking state, so that external gas is prevented from entering the bladder 3. When the gas is required to be safely analyzed after sampling is finished, the third end of the tee joint 5 is in an open state and can be connected with a gas detection device. After sampling and gas safety analysis are completed, when the bladder 3 is cleaned, cleaning liquid can flow out through the third end of the tee joint 5, so that the bladder 3 is free from being detached.
In some embodiments, as shown in fig. 1, one end of the duplex ball 2 is sleeved outside the first end of the tee 5 to form a sealed connection, and one end of the bladder 3 is sleeved outside the second end of the tee 5 to form a sealed connection. Because the material of the duplex ball 2 and the bladder 3 is rubber and elastic, sealing can be realized between two parts with different sizes. The whole normal pressure sampling device for the pesticide intermediate workshop is hermetically connected so as to facilitate the transmission of pressure, and further promote the gas in the normal pressure sampling device for the pesticide intermediate workshop to be discharged and the gas in the reaction kettle or in the pipeline to enter the normal pressure sampling device for the pesticide intermediate workshop.
In some embodiments, as shown in fig. 1, the sealing sleeve 4 is made of rubber, and the rubber has elasticity and can be tightly sleeved outside the sampling tube 1 and the duplex ball 2 to form a sealed connection.
In some embodiments, as shown in fig. 1, the sampling tube 1 is made of glass or steel, and is specifically selected according to the corrosion susceptibility of the gas to be sampled.
In some embodiments, as shown in fig. 1, the end of the sampling tube 1 away from the duplex ball 2 for sampling is equipped with a filter cotton 6 to prevent the sampling end of the sampling tube 1 from contacting liquid or solid impurities in the reaction kettle or pipeline, which results in impure gas for sampling.
In some embodiments, as shown in fig. 1, the duplex ball 2 and the bladder 3 are made of rubber, which is elastic at room temperature, and can be deformed greatly under the action of a small external force, and can be restored to the original shape after the external force is removed. The duplex ball 2 is made of rubber, so that the operation is more labor-saving, and the bladder 3 is made of rubber and can store more gas to be sampled.
In some embodiments, as shown in FIG. 1, the sphere (also referred to as first sphere 201) of duplex sphere 2 near the end of coupon 1 is larger in size than the sphere (also referred to as second sphere 202) near the end of bladder 3. One end of the first sphere 201 of the duplex sphere 2, which is far away from the second sphere 202, is provided with an opening and a piston which is in one-way communication, when the duplex sphere is used, the first sphere 201 is extruded, the piston jumps out of the first sphere 201, so that the gas in the duplex sphere 2 is discharged out of the duplex sphere 2 through the opening, at the moment, the gas pressure in the duplex sphere 2 is smaller than the external gas pressure, and under the action of the gas pressure gradient force, the external gas pressure pushes the gas to be sampled in the reaction kettle or in the pipeline to enter the sampling tube 1 and the duplex sphere 2. The extruded first sphere 201 is loosened, the piston falls back to block the opening, the gas to be sampled is sealed in the duplex sphere 2 and the bladder 3, and the second sphere 202 plays a role in buffering pressure. The repeated squeezing action can enable the gas in the reaction kettle or in the pipeline to be continuously pressed into the atmospheric pressure sampling device for the pesticide intermediate workshop.
In some embodiments, as shown in fig. 1, the tee 5 is made of stainless steel. Compare in traditional glass material's tee bend 5, the stainless steel tee bend 5 of this application is not fragile more.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
