Description

Technical Field

[0001] The utility model belongs to the technical field of samplers, and particularly relates to a natural gas cumulative sampler. Background Art

[0002] In the manufacturing process of liquefied natural gas, in order to master the product quality of liquefied natural gas, it is necessary to use a sampler to take a certain amount of samples from the storage tank for analysis. Therefore, it can be seen that the existing samplers basically meet people's practical needs, but there are still the following problems.

[0003] When using the sampler, the operator first opens the valves on both sides of the sampler, and then the operator connects the sampler, and connects the connection port of the sampler with the connection port of the pipeline. When the pipeline ports are connected, the natural gas in the pipeline flows into the sampling tank, so as to sample the natural gas. For this reason, we propose a natural gas cumulative sampler. Content of the Utility Model

[0004] The utility model provides a natural gas cumulative sampler. The sealing block drives the sealing plug to insert into the connection port to seal the connection port, avoiding the connection port being blocked by other objects after the sampling tank is no longer used, and improving the usability of the sampling tank.

[0005] To achieve the above object, the utility model provides the following technical solution: A natural gas cumulative sampler, including a sampling tank, valves and connection ports. Valves are installed at both ends of the sampling tank, and connection ports are installed at the ends of the valves. A connecting plate is attached to the surface of the valve, and rotating shafts fixed on the valve penetrate through the ends of the connecting plate. The ends of the connecting plate are elastically connected with sealing blocks, and sealing plugs inserted into the connection ports are fixed in the middle of the sealing blocks.

[0006] Further, a handle is arranged on the surface of the sampling tank, and sliding blocks are fixed at both ends of the handle. Slide grooves fixed on the sampling tank are sleeved on the surfaces of the sliding blocks. Receiving grooves are symmetrically opened in the middle of the handle, and support frames are inserted into the middle of the receiving grooves. Rotating rods fixed on the inner wall of the receiving groove penetrate through the ends of the support frames, and the support frames are connected with the receiving grooves for limit.

[0007] Further, a traction plate is opened in the middle of the handle, and a first spring and a traction rod are respectively arranged inside the traction plate. Both ends of the first spring abut against the ends of the traction rod. Blocks are fixed at the ends of the traction rod, and the blocks are attached to the surface of the support frame.

[0008] Further, the ends of the receiving groove close to the rotating rod are all set as inclined slopes.

[0009] Further, traction plates are fixed to both ends of the sealing block, and traction blocks are fixed to the sides of the traction plates that are in contact with the connecting plate. Traction grooves are formed in the connecting plate and sleeved on the surfaces of the traction blocks. Second springs are arranged inside the traction grooves and are respectively abutted between the inner walls of the traction grooves and the surfaces of the traction blocks.

[0010] Further, the rotating shafts are all cylindrical. Cylindrical through holes are formed in the sides of the connecting plates penetrated by the rotating shafts, and the cylindrical through holes formed in the sides of the connecting plates penetrated by the rotating shafts are matched with the cylindrical shapes of the rotating shafts.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The natural gas cumulative sampler is provided with rotating shafts, connecting plates, sealing blocks and sealing plugs. By the operator pulling the sealing block, the sealing block rotates on the surface of the rotating shaft through the connecting plate, and the connecting plate drives the sealing plug to move through the sealing block, so that the sealing plug is moved out of the connection port. After the sealing block no longer blocks the connection port through the sealing plug, the connection port is opened. After the connection port is sealed by the sealing block driving the sealing plug, it is avoided that other sundries are inserted into the middle of the connection port after the operator no longer uses the sampling tank, and the connection port is prevented from being blocked, thus improving the usability of the sampling tank.

[0013] 2. The natural gas cumulative sampler is provided with a storage groove, a rotating rod and a support frame. By the operator pulling the support frame, the support frame rotates through the rotating rod, so that the support frame is moved out of the storage groove. The support frame supports the sampling tank through the handle. Since the support frame supports the sampling tank, it is convenient for the operator to place the sampling tank on the ground.

The ends of the connecting plate 5 are elastically connected to a sealing block 6, and the middle of the sealing block 6 is welded with a sealing plug 20 inserted into the connection port 3. The ends of the sealing block 6 are welded with a traction plate 16, and the traction plate 16 and the connecting plate 5 are attached to each other on one side. The traction block 18 is welded with each other, and the surface of the traction block 18 is sleeved with a traction groove 17 provided on the connecting plate 5. The traction groove 17 is provided with a second spring 19 respectively abutting between the inner wall of the traction groove 17 and the surface of the traction block 18. When the operator uses the sampling tank 1, the operator first pulls the sealing block 6, and the sealing block 6 drives the sealing plug 20 to move. When the sealing plug 20 moves, the sealing plug 20 drives the traction block 18 to move in the traction groove 17. When the traction block 18 moves in the traction groove 17, the traction The block 18 squeezes the second spring 19. After the traction block 18 is squeezed by the second spring 19, the second spring 19 undergoes elastic deformation, and the second spring 19 avoids the traction block 18, so that the traction plate 16 slides on the surface of the connecting plate 5, so that the sealing block 6 drives the sealing plug 20 to move out of the connecting port 3. The operator opens the connecting port 3. When the connecting port 3 is opened, the operator pulls the sealing block 6, and the sealing block 6 drives the traction block 18 to move through the traction plate 16. The traction block 18 drives the connecting plate 5 through the traction groove 17. 5 moves, and the end of the connecting plate 5 is rotated on the surface of the rotating shaft 4 through the circular through hole opened on one side of the rotating shaft 4, so that the connecting plate 5 drives the sealing block 6 to move out from the front end of the connecting port 3, and the operator opens the connecting port 3. Then the operator takes the sampling tank 1, so that the sampling tank 1 drives the connecting port 3 to be connected with the pipeline through the valve 2, and drives the sealing plug 20 to be inserted into the connecting port 3 through the sealing block 6 to seal the connecting port 3, so as to prevent other objects from being inserted into the connecting port 3 when the operator no longer uses the connecting port 3, thereby improving the usability of the connecting port 3.

[0025] In other embodiments, a handle 9 is provided on the surface of the sampling tank 1, and sliders 8 are welded to both ends of the handle 9, and the surfaces of the sliders 8 are sleeved with slide grooves 7 welded to the sampling tank 1, and a storage groove 15 is symmetrically opened in the middle of the handle 9, and a support frame 11 is inserted in the middle of the storage groove 15, and the ends of the support frame 11 are penetrated by a rotating rod 10 welded to the inner wall of the storage groove 15, and the support frame 11 is limitedly connected to the storage groove 15, and the end of the storage groove 15 close to the rotating rod 10 is set to an inclined slope, when the operator needs to support the sampling tank 1 The operator first pulls the support frame 11, and the support frame 11 is rotated on the surface of the rotating rod 10 through the circular through hole on one side of the rotating rod 10, so that the support frame 11 is rotated out of the storage groove 15, and when the support frame 11 is rotated out of the storage groove 15, the surface of the support frame 11 and the inclined slope set inside the storage groove 15 fit each other, so that the support frame 11 restricts the storage groove 15, and the support frame 11 is restricted to the bottom end of the handle 9, so that the support frame 11 supports the sampling tank 1 through the handle 9, thereby improving the stability of the sampling tank 1 placed on the ground.

[0026] In other embodiments, a traction plate 16 is provided in the middle of the handle 9, and a first spring 14 and a traction rod 13 are respectively provided inside the traction plate 16, both ends of the first spring 14 are in contact with the ends of the traction rod 13, and both ends of the traction rod 13 are welded with a stopper 12, and the stopper 12 is attached to the surface of the support frame 11. When the operator moves the support frame 11 into the storage groove 15, the operator presses the stopper 12 to make the stopper 12 push the traction rod 13 to slide in the traction plate 16, and when the traction rod 13 slides in the traction plate 16, the traction rod 13 squeezes the first spring 14, and the first spring 14 is elastically deformed by the traction rod 13 squeezing the first spring 14, and the elastic deformation of the first spring 14 occurs. After the deformation, the first spring 14 avoids the traction rod 13, so that the block 12 moves to the inner wall of the storage groove 15, and the block 12 avoids the support frame 11. Then the operator inserts the support frame 11 into the storage groove 15. When the support frame 11 is inserted into the storage groove 15, the operator releases the block 12. After the block 12 no longer squeezes the first spring 14 through the traction rod 13, the elastic deformation of the first spring 14 is restored. The first spring 14 pushes the block 12 to move through the traction rod 13, so that the block 12 abuts on the surface of the support frame 11. When the block 12 abuts on the surface of the support frame 11, the support frame 11 is fixed in the storage groove 15, thereby improving the stability of the support frame 11 stored in the storage groove 15.
