DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides an embodiment: a gas-solid two-phase flow velocity measuring device with good sealing performance, comprising:

[0024] A connecting pipe 1, a first connecting assembly 3 is arranged above the connecting pipe 1, and second connecting assemblies 4 are arranged at both ends of the connecting pipe 1;

[0025] The first connection component 3 includes a threaded barrel 31, which is integrally formed above the connection pipe 1. An extrusion sleeve 32 is provided on the outer wall of the threaded barrel 31. The outer thread of the extrusion sleeve 32 is connected to a screw sleeve 33. The outer thread of the threaded barrel 31 is connected to the measuring instrument 2. Through the arrangement of this structure, after the measuring instrument 2 is threadedly connected, its outer part can be extruded and wrapped, so that the sealing performance of the connection of the measuring instrument 2 is improved through the cooperation between the inner and outer parts.

[0026] The second connecting component 4 includes a positioning flange 41, and a first set of clamps 42 is fixedly connected to the outer wall of the positioning flange 41. A second set of clamps 44 is connected to the top of the first set of clamps 42. Through the arrangement of the first set of clamps 42 and the second set of clamps 44, the circumference of the positioning flange 41 after connection can be wrapped and sealed. At the same time, the first set of clamps 42 can provide auxiliary support for the positioning flange 41 when it is connected, thereby further improving the convenience of its connection and achieving a good supporting effect.

[0027] Furthermore, two groups of second connecting components 4 are provided, and the two groups of second connecting components 4 are symmetrically distributed at two ends of the connecting pipe 1 .

[0028] Furthermore, the connecting pipe 1 , the threaded barrel 31 and the positioning flange 41 are integrated into one structure, the threaded barrel 31 is provided with a first external thread on its exterior, and the positioning flange 41 is evenly provided with positioning holes.

[0029] Furthermore, the exterior of the extrusion sleeve 32 is a conical structure, and the outer wall of the conical structure is provided with a second external thread, and the inner wall of the screw sleeve 33 is provided with an internal thread adapted to the extrusion sleeve 32. Through the setting of the conical structure of the extrusion sleeve 32, the extrusion sleeve 32 can be gradually tightened under the cooperation of the threaded connection of the screw sleeve 33, thereby completing the wrapping of the exterior of the measuring instrument 2. The inner wall of the extrusion sleeve 32 is provided with a sealing gasket, and the setting of the sealing gasket further improves the sealing of its wrapping. The outer wall of the screw sleeve 33 is provided with anti-slip grooves, and the setting of the anti-slip grooves increases the friction in contact with the hand.

[0030] Furthermore, a positioning ring 43 is fixedly connected to the upper surface of the first set of clamps 42, a limiting ring is provided on the side of the positioning flange 41 away from the connecting pipe 1, and a sealing gasket 45 is provided on the outer sleeve of the limiting ring. The thickness of the sealing gasket 45 is greater than the thickness of the limiting ring. By setting the thickness of the sealing gasket 45, it has a certain pressure sealing effect. Positioning ears are provided at both ends of the second set of clamps 44 and the first set of clamps 42, and bolts are passed through the inside of the positioning ears. The inner walls of the first set of clamps 42 and the second set of clamps 44 are both provided with sealing gaskets, which further wrap and seal the outside of the positioning flange 41, thereby improving the sealing effect of the positioning flange 41 docking. At the same time, the auxiliary support of the first set of clamps 42 can support the positioning flange 41, thereby avoiding its supporting force from acting on the bolts passing through the inside of the positioning flange 41, thereby ensuring the stability of its connection. The sum of the widths of the second set of clamps 44 and the positioning ring 43 is equal to the width of the first set of clamps 42.

[0031] Working principle: The connecting pipe 1 and measuring instrument 2 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When using the utility model, the various components are first installed, and the measuring instrument 2 is first installed so that it is threadedly connected to the threaded barrel 31, and then the extrusion sleeve 32 is compressed and contracted by rotating the screw sleeve 33 to complete the sealing wrapping of the outside of the connection of the measuring instrument 2. At the same time, when the positioning flange 41 is externally docked, the first set of clamps 42 plays an auxiliary supporting role, and the second set of clamps 44 is further covered on the top of the positioning flange 41, and the first set of clamps 42 are locked to achieve the wrapping and sealing of the outside of the positioning flange 41.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
