Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0027] A steam flow meter control device comprises a steam flow meter body 1, transmission pipes 2 are installed at both the front and rear ends of the steam flow meter body 1, two groups of transmission pipes 2 are fixedly connected to the steam flow meter body 1 through a connector 3, a fastening mechanism 4 is installed on the inner side of the connector 3, a sealing box 5 is fixedly connected to the outer side of the rear end of the steam flow meter body 1, a control plug plate 6 is slidably connected to the inner side of the sealing box 5, an adjusting screw 7 is rotatably connected to the inner side of the sealing box 5 and located on the back side of the control plug plate 6, the control plug plate 6 is threadedly connected to the adjusting screw 7 through a connecting plate 8, and a locking mechanism 9 is installed at the top of the adjusting screw 7 and located on the outer side of the sealing box 5.

[0028] First, the connector 3 is composed of two groups of connecting sleeves 301, and the left and right ends of the two groups of connecting sleeves 301 are fixedly connected by bolts 302. The first sealing sleeve 303 is fixedly connected between the two groups of connecting sleeves 301 and the steam flow meter body 1 and the transmission pipe 2. After the connecting sleeve 301 connects and fixes the connection between the steam flow meter body 1 and the transmission pipe 2, the first sealing sleeve 303 is used to ensure the sealing of the connection between the steam flow meter body 1 and the transmission pipe 2. Since the transmission pipe 2 at the front section of the steam flow meter body 1 introduces steam, and the transmission pipe 2 at the rear end is used to export steam, when the steam flow meter body 1 and the transmission pipe 2 are separated, only the rear end of the steam flow meter body 1 and the transmission pipe 2 need to be separated, and only a small number of bolts 302 need to be unscrewed to open the two groups of connecting sleeves 301, so as to facilitate and quickly separate the rear end of the steam flow meter body 1 and the transmission pipe 2, thereby improving the work efficiency of the maintenance personnel.

[0029] Then, the fastening mechanism 4 includes a plurality of groups of top columns 401 slidably connected to the inner sides of the two groups of connecting sleeves 301, and a fastening block 402 is fixedly connected to one end of the plurality of top columns 401 near the connection between the steam flow meter body 1 and the transmission pipe 2, and a first spring 403 is sleeved on one end of the plurality of top columns 401 away from the fastening block 402, and a top ring 404 is fixedly connected to the outer side of the top column 401 and located at one end of the first spring 403 near the fastening block 402, and the plurality of top columns 401 are evenly spaced and distributed on the inner side of the connecting sleeve 301. , multiple groups of fastening blocks 402 are designed in a trapezoidal structure. When the connecting sleeve 301 is installed at the connection between the steam flow meter body 1 and the transmission pipe 2, the trapezoidal fastening block 402 is first contracted, and then fixed by bolts 302 after the connecting sleeve 301 is installed. Under the pressure of the first spring 403, the top ring 404 is pushed, so that the fastening block 402 is tightly pressed against the outer side of the connection between the steam flow meter body 1 and the transmission pipe 2, further ensuring the firmness of the connection between the steam flow meter body 1 and the transmission pipe 2.

[0030] Secondly, a sealing gasket 501 is fixedly connected to the connection between the inside of the sealing box 5 and the control plug plate 6, and rollers 601 are rotatably connected to the front and rear ends of the top of the control plug plate 6, and the rollers 601 fit the surface of the sealing gasket 501. A second sealing sleeve 602 is fixedly connected to the inner side of the steam flow meter body 1 and located at the connection of the control plug plate 6. When the rear end of the steam flow meter body 1 and the transmission pipe 2 are separated, the steam needs to be closed first. At this time, the control plug plate 6 is inserted into the inner side of the steam flow meter body 1 by rotating the adjusting screw 7 under the connection of the connecting plate 8, and the sealing gasket 501 and the second sealing sleeve 602 are used to ensure the sealing, and the steam is closed. During the movement of the control plug plate 6, the roller 601 assists in rolling, thereby ensuring the movement stability of the control plug plate 6. At the same time, the flow rate of steam passing through can be controlled by adjusting the insertion depth of the control plug plate 6.

[0031] Finally, the locking mechanism 9 includes a knob 901 fixedly connected to the top of the adjusting screw 7, a fixed gear 902 is fixedly connected to the outside of the adjusting screw 7 and located below the knob 901, a connecting block 903 is fixedly connected to the top of the sealing box 5 and located outside the fixed gear 902, a pull rod 904 is slidably connected inside the connecting block 903, a tooth block 905 is fixedly connected to one end of the pull rod 904 close to the tooth block 905, a second spring 906 is sleeved on the outside of the pull rod 904 and located between the tooth block 905 and the connecting block 903, The right end of the rod 904 is fixedly connected with a pull handle 907, and the tooth block 905 is meshed with the fixed gear 902. When controlling the control plug board 6, the pull rod 904 is first pulled by the pull handle 907 to make the tooth block 905 disengage from the fixed gear 902, thereby releasing the fixation of the adjusting screw 7, and then the adjusting screw 7 is rotated by the knob 901 to control the control plug board 6. After the adjustment of the control plug board 6 is completed, the pull handle 907 is released so that the tooth block 905 fixes the fixed gear 902, thereby locking the adjusting screw 7.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the connecting sleeve 301 is installed at the connection between the steam flow meter body 1 and the transmission pipe 2, the trapezoidal fastening block 402 is first contracted, and then fixed by the bolt 302 after the connecting sleeve 301 is installed, and the top ring 404 is pushed under the pressure of the first spring 403, so that the fastening block 402 is tightly against the outer side of the connection between the steam flow meter body 1 and the transmission pipe 2. Since the transmission pipe 2 at the front section of the steam flow meter body 1 introduces steam, and the transmission pipe 2 at the rear end is used to export steam, when the steam flow meter body 1 and the transmission pipe 2 are separated, it is only necessary to separate the rear end of the steam flow meter body 1 from the transmission pipe 2, and only a small number of bolts 302 need to be unscrewed to open the two sets of connecting sleeves 301, so as to facilitate and quickly separate the rear end of the steam flow meter body 1 and the transmission pipe 2. When the rear end of the steam flow meter body 1 and the transmission pipe 2 are separated, it is necessary to close the steam first. The steam flow meter 1 is controlled by rotating the adjusting screw 7 and inserting the control plug plate 6 into the inner side of the steam flow meter body 1. The sealing gasket 501 and the second sealing sleeve 602 are used to ensure the sealing performance. The steam outlet is closed. At the same time, the insertion depth of the control plug plate 6 can also be adjusted to control the flow rate of the steam. When controlling the control plug plate 6, the pull rod 904 is first pulled by the pull handle 907 to make the tooth block 905 disengage from the fixed gear 902, thereby releasing the fixation of the adjusting screw 7. Subsequently, the adjusting screw 7 is controlled by rotating the knob 901. After the control plug plate 6 is adjusted, the pull handle 907 is released to make the tooth block 905 fix the fixed gear 902, thereby locking the adjusting screw 7. The whole operation process is simple and convenient. Compared with the existing steam flow meter, the utility model can control the steam closing through design, and at the same time improves the work efficiency of the maintenance personnel.
