Description

Technical Field

[0001] The utility model relates to the technical field of liquid sampling, and in particular to a liquid sealed sampler which is convenient to use. Background Art

[0002] In the petrochemical production process, it is often necessary to sample flammable, explosive, toxic and harmful media in special pipelines for testing and analysis. In order to collect samples in time and prevent volatile substances in the samples from leaking into the atmosphere, many sampling operations require closed sampling. During sampling, many products even need to be cooled and depressurized before sampling. These special sampling operations must be carried out with the aid of closed samplers.

[0003] When using the existing liquid sealed sampler, connecting the sampling bottle to the sampler is time-consuming and laborious, which increases the workload, affects the user's use, and greatly reduces the sampling efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid sealed sampler which is easy to use in view of the defects of the prior art, so as to solve the problem that when using the existing liquid sealed sampler, connecting the sampling bottle with the sampler is time-consuming and laborious, which increases the work intensity, affects the use of the user, and greatly reduces the sampling efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A convenient liquid sealed sampler comprises a sampler body, a sampling area is provided at the front end of the sampler body, a sampling tube connected to the sampler body for liquid introduction is provided on the sampling area, a sealing soft board is installed at the port of the sampling tube, a carrying plate for supporting a sampling bottle is provided at the bottom of the sampling tube, a placement groove is provided on the carrying plate and is located directly below the sampling tube, a first guide block is provided on the side of the carrying plate close to the sampling area, a fixing plate is provided on one side of the sampler body, a driving threaded hole is provided through the fixing plate, a driving threaded rod is screwed in the driving threaded hole, a driving wheel is extended upward from the top of the driving threaded rod, and a driving plate is extended downward from the bottom of the driving threaded rod and is rotatably connected to the driving plate, and a second guide block is provided on the side of the driving plate close to the sampler body.

[0007] In order to support the middle of the sampling bottle and improve the stability of sampling, baffles that are symmetrically arranged and have an arc-shaped structure are provided on the top end surfaces of the supporting plates on both sides of the placement groove.

[0008] In order to improve the stability of the sampling bottle when it moves up and down for sampling, a first guide groove capable of allowing the first guide block to move up and down is provided on the inner end surface of the sampling area.

[0009] In order to further improve the stability of the sampling bottle when it moves up and down for sampling, a second guide groove capable of allowing the second guide block to move up and down is provided on the sampler body.

[0010] As a preferred technical solution of the present invention, the driving plate and the bearing plate are connected by welding.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When in use, the staff first places the sampling bottle in the placement groove on the supporting plate from between the two baffles, and the staff rotates the driving wheel so that the driving plate drives the supporting plate to move upward, and moves the sampling bottle on the supporting plate closer to the sampling tube until a part of the sampling tube is inserted into the bottle mouth of the sampling bottle, and the outer periphery of the bottle mouth of the sampling bottle abuts against the sealing soft plate on the sampling tube, so that the sealing soft plate is deformed to fill a part of the sealing soft plate in the gap between the sampling bottle and the sampling tube, thereby improving the sealing of the sampling. The utility model improves the connection efficiency between the sampling tube and the sampling bottle during sampling, and can also provide fixed support for the sampling bottle during sampling, thereby improving the convenience and work efficiency of the staff during sampling.
