Description

TECHNICAL FIELD

[0001] The utility model relates to the measuring appliance technical field of butterfly valve sealing ring, specifically is a vernier caliper special for butterfly valve sealing ring. BACKGROUND

[0002] The measurement of the butterfly valve, especially the measurement of the internal sealing ring size of the three-eccentric butterfly valve, usually needs to use a special measuring tool, because the structure of the three-eccentric butterfly valve is irregular, as shown in the figure, the half-partial structure below the vernier caliper is the butterfly valve body 10 of the three-eccentric butterfly valve, and when the butterfly valve body is produced, the valve body sealing ring 100 integrally formed with the butterfly valve body 10 needs to be made into two inclined surfaces, i.e. the first sealing surface 101 and the second sealing surface 102 in opposite directions, and the inclination angles of the inclined surfaces are different, so the error of the measurement using the traditional measuring tool and method is large. Figure 3

DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of the utility model protection.

[0020] As Figure 1 , Figure 2 and Figure 3 indicated, the utility model discloses a vernier caliper special for butterfly valve seal ring, and the vernier caliper is used for measuring the size of valve body seal ring 100 in butterfly valve body 10 as Figure 3 indicated, and the valve body seal ring 100 and butterfly valve body 10 on the market are usually integrally formed;Specifically, the vernier caliper comprises main ruler 1 marked with scale and main vernier 2 slidably connected to main ruler 1, and further, the bottom surface of main ruler 1 and main vernier 2 respectively forms fixed measuring claw 11 and movable measuring claw 21, the claw end of fixed measuring claw 11 is formed with fixed measuring slope 12 for cooperating with first sealing surface 101 of seal ring 100, the claw end of movable measuring claw 21 is formed with movable measuring slope 22 for cooperating with second sealing surface 102 of seal ring 100, the slope of fixed measuring slope 12 is opposite to that of first sealing surface 101, so that fixed measuring slope 12 and first sealing surface 101 can be attached together during measurement, and similarly, movable measuring claw 21 and second sealing surface 102 have the same slope and opposite direction, so that the attachment effect can also be achieved;During use, fixed measuring slope 12, movable measuring slope 22 and the scale of main ruler 1 are used to realize size measurement.

[0021] Further, the depth gauge assembly 3 is arranged on the main ruler 1 for abutting the flange end surface 103 of the butterfly valve body 10 during measurement. The present application further comprises a linkage assembly 7 mounted to the main vernier ruler 2, which is slidingly connected to the depth gauge assembly 3 through a linkage slider 5. Specifically, as shown in Figure 3 the depth gauge assembly 3 comprises a depth gauge seat 31 fixed on the main ruler 1 and a depth ruler 32 slidingly connected in the depth gauge seat 31. The upper end of the depth ruler 32 is fixedly connected to one end of the linkage slider 5 through a connecting seat 4, and the other end of the linkage slider 5 is slidingly connected to the linkage assembly 7.

[0022] In order to realize the linkage of the depth ruler 32 and the linkage assembly 7 in the vertical direction, specifically, as shown in Figure 2 the linkage assembly 7 comprises a linkage ruler 71 and a sliding seat 72. The sliding seat 72 is fixedly arranged on the main vernier ruler 2, and the linkage ruler 71 is slidingly connected in the sliding seat 72. In order to make the depth of the depth ruler 32 and the linkage ruler 71 the same after adjusting the depth values of the depth ruler 32 and the linkage ruler 71, the bottom end surface of the linkage ruler 71 is flush with the bottom end surface of the depth ruler 32.

[0023] More specifically, as shown in Figure 2 a sliding block 6 is fixedly arranged on the upper part of the linkage ruler 71. The side surface of the sliding block 6 forms a guide hole in the length direction of the main ruler 1, and the linkage slider 5 is slidingly inserted in the guide hole. Thus, the depth ruler 32 and the linkage ruler 71 can slidingly move in the vertical direction in linkage and synchronization, and the entire linkage assembly 7 can slidingly move along with the sliding of the main vernier ruler 2 in the horizontal direction (i.e. in the length direction of the main ruler 1).

[0024] During measurement, it is necessary to adjust the depth ruler 32 and the linkage ruler 71 to a certain depth value and then lock and fix them. Because, when measuring the sealing ring 100 of the butterfly valve body 10, it is necessary to fix the measuring claw 11 and the movable measuring claw 21 to a certain depth (the position of the sealing ring 100) of the flange end surface 103 of the butterfly valve body 10 for measurement. Therefore, it is necessary to keep the depth ruler 32 and the linkage ruler 71 fixed in the vertical direction during measurement. Thus, further optimization is made, as shown in Figure 1 the depth gauge seat 31 is threadedly connected with a second locking piece 33

[0025] Specifically, the depth gauge seat 31 forms a threaded hole, and the lower part of the second locking piece 33 forms a threaded rod which is threadedly connected to the threaded hole. The second locking piece 33 can be screwed against the depth ruler 32 to lock and fix the depth ruler 32.

[0026] Of course, during measurement, in order to fix the relative sliding of the main vernier scale 2 with respect to the main ruler 1 so that the user can take a reading, the main vernier scale 2 is threadedly connected to a first locking member 23. Similar to the second locking member 33 mentioned above, the first locking member 23 can be tightened and pressed against the depth ruler 32 to fix the main vernier scale 2 and the main ruler 1.

[0027] When using, such as Figure 3 As shown, according to the distance from the valve body sealing ring 100 to the flange end face 103 of the butterfly valve body 10 as required by the drawing, adjust the depth ruler 32 and the linkage ruler 71 to the same depth value as this distance, and tighten them with the second locking piece 33. Then slide the main vernier scale 2 to make the fixed measuring inclined surface 12 and the movable measuring inclined surface 22 abut against the first sealing surface 101 and the second sealing surface 102 respectively. Finally, read the scale value on the main ruler 1, which is the distance between the first sealing surface 101 and the second sealing surface 102.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
