[0002] Corrosion-resistant valves are devices used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] Most of the existing corrosion-resistant valve installation methods use flange connection. During installation, it is necessary to align the mounting holes on the valve flange with the mounting holes on the pipe flange, and then connect and fix them by passing bolts through the two flanges. In actual operation, since there is no limit at the initial stage of docking the corrosion-resistant valve and the pipe flange, the corrosion-resistant valve is easy to shift when the corrosion-resistant valve is rotated and adjusted. The mounting holes on the valve flange and the mounting holes on the pipe flange are not easy to align quickly, and it takes a lot of time to complete the final alignment. In order to simplify this operation, a corrosion-resistant flange valve faucet is provided. Utility Model Content

[0024] 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.

[0025] See also Figures 1 to 3 In an embodiment of the utility model, a corrosion-resistant flange valve faucet includes a flange valve 1 composed of a valve body 101 and a connecting flange 102. The connecting flanges 102 are symmetrically fixed to both ends of the valve body 101. An installation auxiliary component 2 is provided on the outer side of the valve body 101 and the connecting flange 102. The installation auxiliary component 2 is used to realize the limiting alignment of the connecting flange 102 and the pipeline flange and provide support for the overall rotation of the flange valve 1.

[0026] The installation auxiliary component 2 includes a rotation support unit and a limit unit;

[0027] The rotation support unit is used to enable the flange type valve 1 to be rotatably adjusted with the pipeline flange as a base, so as to realize rapid alignment of the mounting holes of the connecting flange 102 and the pipeline flange;

[0028] The limiting unit is used to limit the position of the retracted state and the extended state of the rotating support unit;

[0029] The rotating support unit includes an annular seat 201 and a rotating roller 202;

[0030] A plurality of rotating rollers 202 are provided, and the plurality of rotating rollers 202 are evenly distributed in a ring shape at one end of the annular seat 201, and the rotating rollers 202 are rotatably connected to the annular seat 201;

[0031] A plurality of rotating rollers 202 are attached to the outside of the connecting flange 102. The connecting flange 102 is horizontally aligned with the external flange by the rotating rollers 202 moving horizontally to fit the outside of the external flange. The plurality of rotating rollers 202 can provide support for the overall rotation of the flange type valve 1.

[0032] The annular seat 201 is provided with a circular hole for the rotating roller 202 to pass through, the outer side of the rotating roller 202 is integrally formed with an annular groove 205, and the inner side of the circular hole is fixed with a limiting ring block 206 that is rotatably sleeved with the annular groove 205;

[0033] The limiting unit includes a limiting block 203 and a fastening bolt 204;

[0034] A plurality of limit blocks 203 are provided, and the plurality of limit blocks 203 are distributed in an annular shape and fixed to the outside of the valve body 101. The annular seat 201 is located between the limit blocks 203 and the connecting flange 102. The limit blocks 203 are used to limit the movement of the annular seat 201 away from the connecting flange 102.

[0035] The fastening bolt 204 is threadedly connected to a limiting block 203 and penetrates the limiting block 203 to fit with the annular seat 201 . The fastening bolt 204 is used to limit the state of the annular seat 201 close to the connecting flange 102 .

[0036] In this embodiment, it is necessary to add that: the flange valve 1 is a heavy valve type, and it is inconvenient to keep the valve body 1 balanced during installation. Therefore, auxiliary installation can be performed by installing the auxiliary component 2. The operation steps are as follows:

[0037] First, move the two annular seats 201 close to the limit block 203, at which time the end surface of the rotating roller 202 is flush with the end surface of the connecting flange 102, and then transfer the valve body 1 to the position to be installed, and the two connecting flanges 102 are respectively aligned with the pipe flanges on the two external pipes;

[0038] Then, the annular seat 201 is pushed close to the connecting flange 102, and the rotating roller 202 is synchronously moved to the outside of the pipeline flange, so that the connecting flange 102 and the pipeline flange are kept in a horizontal alignment state. At this time, the bottom support of the flange valve 1 can be released, and only a slight balancing force is needed to be applied to the flange valve 1 to maintain the rotation direction;

[0039] Then, tighten the fastening bolt 204 to move it to fit the end surface of the annular seat 201, so that the horizontal position of the annular seat 201 remains stable, so as to facilitate the subsequent rotation adjustment of the flange valve 1;

[0040] Afterwards, the flange valve 1 can be rotated as a whole according to the misalignment of the mounting holes of the connecting flange 102 and the pipe flange. At this time, the flange valve 1 is rotated along the pipe flange by the rotating roller 202, and the rotating roller 202 can rotate by itself to reduce the friction resistance during the rotation process. When the mounting holes of the connecting flange 102 and the pipe flange are aligned, the mounting holes can be penetrated by bolts for reinforcement. Compared with the transmission adjustment operation, it is not only more labor-saving, but also has a higher overall installation efficiency.

[0041] Please refer to Figures 1-2The inner wall diameter of the annular seat 201 is larger than the outer diameter of the distribution track of the mounting holes on the connecting flange 102, and the limit block 203 and the mounting holes on the connecting flange 102 are staggered along the circumferential direction.

[0042] In this embodiment: this structure can prevent the annular seat 201 and the limit block 203 from interfering with the subsequent bolt fixing, thereby ensuring smooth installation of the flange valve 1.

[0043] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
