Description

Technical Field

[0001] The utility model relates to the technical field of water sampling in boiler delivery pipelines, in particular to a boiler water pipeline sampling device. Background Art

[0002] The main purpose of boiler water treatment is to prevent scaling, corrosion, deposition and steam-water entrainment of boiler water. Through appropriate chemical treatment, the water quality index and steam index can reach the range specified by national standards to ensure the safe and stable operation of steam-using equipment. After the boiler water treatment is completed, the treated water is transported to the designated location through the pipeline for discharge or utilization. In this process, not only the water in the boiler needs to be sampled and tested, but also the water flow in the pipeline needs to be sampled and tested during the transportation process to prevent the impurities or dirt left on the inner wall of the pipeline from being washed out by the water flow, affecting the discharge standard of the water flow. At the same time, the sampled test data can also provide a warning for the cleaning treatment of the inner wall of the pipeline. In the prior art, the sampling of water flow in the pipeline is usually carried out by setting a valve on the pipeline to collect the water flow by opening and closing the valve. However, the sampling operation realized by simply opening and closing the valve has the following problems. First, due to the rapid flow of water inside the pipeline, careless operation when opening the valve can easily lead to excessive overflow of water flow, resulting in a large amount of water flow waste; secondly, the temperature of the water flow in the pipeline is usually high, and there are certain safety hazards in directly draining water through the valve set on the pipeline. Therefore, a boiler water pipeline sampling device is urgently needed to solve the above technical problems. Utility Model Content

[0003] The purpose of the utility model is to provide a boiler water pipeline sampling device, which can divert water in the main pipeline into the sampling pipeline during sampling, and then perform the sampling operation. It is easy to control the sampling amount and is not prone to water spillage. At the same time, it also reduces the safety hazards to sampling personnel due to temperature reasons. It has a simple structure, is easy to operate and has strong practicality.

[0004] The utility model adopts the following technical solutions:

[0005] A boiler water pipeline sampling device comprises a connecting pipeline with flanges at both ends; the connecting pipeline is connected to a drainage pipeline through a drainage port arranged at the top thereof, and a sampling pipeline is arranged on one side of the drainage pipeline; a sealing block for sealing the drainage port is adjustably arranged on the drainage pipeline; and a valve and a temperature measuring meter are arranged on the sampling pipeline.

[0006] Preferably, a screw is threadedly provided on the drainage pipe, and the bottom end of the screw extends into the drainage pipe to be connected with the blocking block.

[0007] Preferably, an operating wheel is provided at the top end of the screw.

[0008] Preferably, the sampling pipe is arranged obliquely upward on one side of the drainage pipe.

[0009] Preferably, the valve is arranged at a position at the bottom of the sampling pipe close to the drainage pipe.

[0010] Preferably, a transparent observation port is provided on the sampling pipe.

[0011] Preferably, a cleaning pipe is threadedly connected to one end of the sampling pipe away from the drainage pipe, a receiving groove is provided on the top wall of the sampling pipe, a drainage sleeve is provided in the receiving groove, and the drainage sleeve is conductively connected to the cleaning pipe; water spray holes are provided along the circumference of the outer wall of the drainage sleeve, and the drainage sleeve is located in the receiving groove in an initial state.

[0012] Preferably, a sealing disk is provided at the end of the drainage sleeve, and the diameter of the sealing disk is larger than the diameter of the drainage sleeve.

[0013] Preferably, a rubber gasket is provided at one end of the sealing disk close to the drainage sleeve.

[0014] Preferably, the cleaning tube is provided with an operating wheel, and a through hole communicating with the cleaning tube is provided in the middle of the operating wheel; a sealing sleeve is detachably provided at one end of the sampling tube away from the drainage tube, and the accommodating groove and the cleaning tube are both provided on the sealing sleeve.

[0015] Compared with the prior art, the utility model has the following beneficial effects: by arranging the connecting pipe between the two sections of boiler water delivery pipes, the utility model can control the sealing block to rise and open the drainage port when sampling is needed, so as to drain the water flow entering the connecting pipe into the drainage pipe, and then adjust the sealing block to close the drainage port. Since the water volume entering the drainage pipe is not large and the water flow does not have the power to flow, a large flow rate will not appear when the water flow is discharged after the valve is opened, which is easy to control, thus avoiding the waste of water flow to a certain extent and reducing safety hazards.

[0016] In addition, by setting a temperature measuring meter on the sampling pipe, the temperature of the water flowing into the sampling pipe can be measured. The display of water temperature can provide a warning to the sampling personnel, enhance the standardization of the sampling operation of the sampling personnel, and further reduce the safety hazards in the sampling process.

[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 4 As shown, a boiler water pipeline sampling device described in the utility model comprises a connecting pipe 1 with flanges at both ends, and the connecting pipe 1 is arranged between the main pipes for conveying boiler water at both ends through flanges; a drainage pipe 2 is arranged at the top of the connecting pipe 1, and a drainage port is arranged at the top of the connecting pipe 1 in the drainage pipe 2, and the drainage pipe 2 is connected with the connecting pipe 1 through the drainage port; a sampling pipe 3 is arranged on one side of the drainage pipe 2; wherein a blocking block 4 for sealing the drainage port is adjustable on the drainage pipe 2, so that by adjusting the blocking block 4, the water flow in the connecting pipe 1 can be guided into the sampling pipe 3; in addition, a valve 5 is arranged on the sampling pipe 3 for releasing the water flow collected in the sampling pipe 3 to complete the sampling operation; a temperature measuring meter 6 is also arranged on the sampling pipe 3, and the temperature measuring meter 6 adopts an industrial high-temperature temperature measuring meter 6, and a display is arranged on the outer wall of the sampling pipe 3, and a probe connected to the display penetrates into the sampling pipe 3, and the display can adopt a type of installing a detachable battery, without additional wiring operation. The temperature measuring meter 6 can measure the temperature of the water flowing into the sampling pipe 3, provide a warning to the sampling personnel, and enhance the safety during the sampling process.

[0023] When sampling is needed, first adjust the blocking block 4 to move upward to expose the connecting point between the sampling pipe 3 and the drainage pipe 2. At this time, the water in the connecting pipe 1 will flow into the sampling pipe 3 under the action of pressure. Then adjust the blocking block 4 to move downward to close the drainage port. At this time, open the valve 5 set on the sampling pipe 3 to take samples. After the water flow is introduced into the sampling pipe 3, there is a lack of external force to drive it. Therefore, after opening the valve 5, there will be no excessive flow rate and high pressure, which can effectively avoid the water spilling due to careless operation, save resources, and ensure safety.

[0024] Furthermore, a screw rod 7 is threadedly provided on the drainage pipe 2, and the bottom end of the screw rod 7 extends into the drainage pipe 2 and is connected to the blocking block 4. In addition, an operating wheel 8 is also provided at the top of the screw rod 7, so that the screw rod 7 can be driven to move up and down by rotating the operating wheel 8 to complete the opening or sealing operation of the blocking block 4 on the drainage port.

[0025] Furthermore, in this embodiment, the sampling pipe 3 is arranged obliquely upward on one side of the drainage pipe 2, and the valve 5 is arranged at the bottom of the sampling pipe 3 near the drainage pipe 2, so as to facilitate the subsequent discharge of the water flow collected in the sampling pipe 3. In addition, a transparent observation port 9 is also provided on the sampling pipe 3, so as to visually observe the amount of water entering the sampling pipe 3 during sampling, thereby improving the convenience of operation.

[0026] Furthermore, in this embodiment, a cleaning tube 10 is threadedly connected to one end of the sampling pipe 3 away from the drainage pipe 2. The cleaning tube 10 is a cylindrical pipe with threads arranged on the outside and a hollow inside. A receiving groove 11 is arranged on the inner top wall of the sampling pipe 3. A drainage sleeve 12 is arranged in the receiving groove 11. The drainage sleeve 12 is conductively connected to the cleaning tube 10. A water spray hole 13 is arranged along the circumference of the outer wall of the drainage sleeve 12. In the initial state, the drainage sleeve 12 is located in the receiving groove 11. By setting the cleaning tube 10 and the drainage sleeve 12, after sampling, the drainage sleeve 12 can be moved out of the receiving groove 11 and into the sampling pipe 3 by rotating the cleaning tube 10. Then, a water source is connected at the end of the cleaning tube 10 to transport clean cleaning water into the sampling pipe 3, so as to realize the cleaning operation of the inner wall of the sampling pipe and improve the accuracy of subsequent sampling.

[0027] Among them, a sealing disk 14 is provided at the end of the drainage sleeve 12, and the diameter of the sealing disk 14 is larger than the diameter of the drainage sleeve 12. In the initial state, the sealing disk 14 is tightly abutted against the inner wall of the sampling pipe 3 to ensure the sealing performance; preferably, in this embodiment, a rubber gasket 15 is provided at one end of the sealing disk 14 close to the drainage sleeve 12 to further enhance the sealing performance of the sealing disk 14 to the receiving groove 11 to prevent water from entering the receiving groove 11 during sampling.

[0028] The cleaning pipe 10 is also provided with an operating wheel 16 to facilitate the rotation and adjustment of the cleaning pipe 10, wherein a through hole communicating with the cleaning pipe 10 is provided in the middle of the operating wheel 16 to ensure that the connection between the cleaning pipe 10 and the external cleaning water pipe is not obstructed; the sampling pipe 3 is detachably provided with a plugging sleeve 17 at one end away from the drainage pipe 2, and the accommodating groove 11 and the cleaning pipe 10 are both provided on the plugging sleeve 17. The plugging sleeve 17 is preferably connected to the sampling pipe 3 by bolts for subsequent inspection and maintenance. In addition, the sampling pipe 3 and the drainage pipe 2 are also connected by a flange, which is convenient for subsequent disassembly and maintenance, and enhances the practicality of the utility model.
