[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one embodiment of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0018] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.
[0019] like Figures 1-3 As shown, this utility model discloses a soda sampler, which is installed in the sampling port of a soda pipeline 3. It includes a connector seat 1, a sampling head 2, and an end plate 8. The connector seat 1 is installed on the outer wall of the soda pipeline 3, and the sampling head 2 is installed on the connector seat 1. The sampling head 2 has a sampling cavity 6 that runs longitudinally through it and has a rectangular cross-section. The sampling head 2 includes an outlet part 5 and a sampling part 4. The sampling part 4 is adapted to the sampling port. Several sampling holes 7 communicating with the sampling cavity 6 are opened on the side wall of the sampling part 4. The end plate 8 is installed at the bottom of the sampling part 4 and is integrally formed with the sampling head 2.
[0020] The connector 1 is fixed to the outer wall of the steam pipe 3, and the sampling part 4 of the sampling head 2 is precisely inserted into the sampling port of the pipe, making the sampler part of the pipeline system.
[0021] The rectangular cross-section structure of the sampling chamber has higher bending stiffness. Under the same external stress, the rectangular chamber is less prone to bending deformation, better maintaining the shape and size stability of the internal flow channel and ensuring a constant sampling flow rate.
[0022] The sampling head 2 and end plate 8 are integrally formed, eliminating the weak points (such as welds and thread roots) formed by welding or threaded connections between the end plate 8 and the sampling body in traditional multi-segment samplers. Under high temperature, high pressure, and media impact, these weak points are stress concentration points, most prone to fatigue cracks and fractures. The integrated structure makes the sampler a robust whole, capable of evenly distributing pipeline vibration and media impact loads, greatly improving its resistance to bending, vibration, and water hammer impact, and largely eliminating the risk of breakage or detachment from the bottom. In embodiments, integral forming may include casting, forging, etc.
[0023] This invention features a core design that integrates the sampling head 2 and the end plate 8, combined with an auxiliary design where the sampling cavity 6 has a rectangular cross-section. This design makes the device simple in structure, easy to install, and reliable in performance. In particular, the integral molding structure provides better impact resistance and a longer service life under high-flow-rate steam and water conditions.
[0024] In one embodiment, the lead-out portion 5 has a teardrop-shaped cross-section, and the outer side of the bottom end of the lead-out portion 5 is connected to the top surface of the connector seat 1. That is, during installation, after the sampling portion 4 is inserted into the sampling port, the connector seat 1 holds the lead-out portion 5 against its outer side, and then the lead-out portion 5 is connected to the connector seat 1, facilitating installation. Simultaneously, it restricts the installation position and depth of the sampling head 2. As long as the sampling portion 4 is inserted into the sampling port and the outer side of the lead-out portion 5 contacts the top surface of the connector seat 1, the installation depth is automatically determined, eliminating the potential for inconsistent installation depths.
[0025] In one embodiment, the outer wall of the sampling section 4 is adapted to the inner wall of the connector seat 1. This further provides full-circumferential, continuous radial support for the sampling head 2. When the medium inside the pipeline impacts the side wall of the sampling section 4, the resulting lateral force (attempting to bend the sampling section 4) is directly transmitted from the outer wall of the sampling section 4 through this tight-fitting surface and the mating surface of the steam-water pipeline 3, and dispersed to the overall structure of the connector seat 1. Ultimately, it is borne by the outer wall of the steam-water pipeline 3, resulting in better impact resistance of the sampler.
[0026] In one embodiment, the sampling part 4 is a cylindrical structure, which facilitates installation and avoids stress concentration that may occur at the corners of rectangular or irregular cross-sections, further improving fatigue resistance.
[0027] In one embodiment, the sampling head 2 and the end plate 8 are forged. The forging process can effectively weld internal defects such as pores and looseness in the raw materials, greatly improving the density and uniformity of the materials.
[0028] In one embodiment, a plurality of sampling holes 7 are arranged along the axial direction of the sampling section 4, and the plurality of sampling holes 7 are arranged in a straight line (single axial array). When the sampler is inserted into the pipe, these holes are located at different longitudinal positions in the radial direction of the pipe.
[0029] In one embodiment, the sampling port 7 is located inside the steam pipe 3 on the side facing the direction of medium flow.
[0030] The sampling port 7, facing the direction of the medium flow, can directly obtain steam and water samples from the mainstream area of the pipeline. The steam and water parameters (such as temperature, pressure, and composition) in the mainstream area are relatively stable and representative, more accurately reflecting the overall condition of the steam and water within the pipeline. The rectangular cross-section sampling chamber 6 provides a regular flow channel for the steam and water entering the sampling port 7. When the steam and water enter the sampling chamber 6 through the sampling port 7 facing the direction of the medium flow, the shape of the rectangular cross-section guides the steam and water to flow in a specific direction, reducing turbulence and eddies within the sampling chamber 6. This allows the steam and water to pass more smoothly through the sampling chamber 6 and exit from the outlet 5, ensuring the continuity and stability of the sampling process. Furthermore, the rectangular cross-section sampling chamber 6 has a relatively uniform geometry, enabling a more uniform distribution of the steam and water entering the sampling chamber 6 across the cross-section.
[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
