DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, 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 those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] The utility model provides a kind of suspension support seat of butterfly valve as Figures 1-4 As shown in the figure, including:

[0025] Mounting bottom plate 1, the top of mounting bottom plate 1 is connected with pedestal 2, one end of the top of pedestal 2 is connected with first support seat 3, and the other end is slidably connected with second support seat 4, butterfly valve 5 is arranged in the arc-shaped groove between first support seat 3 and second support seat 4, and fixing assembly for fixing butterfly valve 5 is arranged in pedestal 2, second support seat 4 is driven to move towards first support seat 3 by screw rod 6 of fixing assembly, so that butterfly valve 5 is clamped and fixed between first support seat 3 and second support seat 4.

[0026] Support rod 7, support rod 7 is provided with two groups and is arranged at the bottom of butterfly valve 5, for supporting butterfly valve 5.

[0027] The fixing assembly includes guide rod 8, the inside of pedestal 2 is provided with slot, screw rod 6 is rotatably connected in the slot by bearing, and the other end of screw rod 6 is rotatably connected with rotary disc 9 after penetrating the threaded cylinder arranged in the inside of pedestal 2.

[0028] One end of the bottom of second support seat 4 is drivingly connected with screw rod 6 through screw nut and screw rod 6, guide rod 8 is connected in the slot, and one end of second support seat 4 in the slot is slidably sleeved on the surface of guide rod 8.

[0029] The top of first support seat 3 and second support seat 4 is connected with positioning block 10, and the inside of positioning block 10 is provided with plug hole, the two sides of butterfly valve 5 are connected with positioning plug 11, and positioning plug 11 is inserted into plug hole.

[0030] The arc-shaped slot on the surface of the first support base 3 and the second support base 4 is provided with a protective pad 12.

[0031] Two groups of sleeves 13 are connected to the bottom of the butterfly valve 5 and the base 2, and the bottom of the two groups of support rods 7 is slidingly connected in the sleeves 13. The bottom of the support rod 7 is slidingly connected with the sliding groove 15 in the sleeve 13 through the sliding block 14.

[0032] The spring 16 is connected between the support rod 7 and the sleeve 13, and the support pad 17 is connected to the top of the support rod 7.

[0033] The second support base 4 is rollingly connected with a plurality of rollers 18 at one end in the slot.

[0034] The suspended support base of the butterfly valve, first, the butterfly valve 5 is placed in the arc-shaped slot between the first support base 3 and the second support base 4. The positioning plug 11 on one side of the butterfly valve 5 is inserted into the slot of the positioning block 10 on the surface of the first support base 3 to complete the preliminary positioning. Then, the rotating disc 9 is rotated, and the rotating disc 9 drives the lead screw 6 to rotate in the slot. Since the bottom of the second support base 4 is drivingly connected with the lead screw 6 through the lead screw nut, and the one end of the second support base 4 in the slot is slidingly sleeved on the surface of the guide rod 8, the guide rod 8 limits the movement direction of the second support base 4, so that it can only move along the direction of the guide rod 8. With the rotation of the lead screw 6, the second support base 4 moves towards the first support base 3, and the positioning plug 11 on the other side of the butterfly valve 5 is inserted into the slot of the positioning block 10 on the surface of the second support base 4. Thus, the butterfly valve 5 is clamped and fixed between the two support bases under the continuous movement of the second support base 4, the installation and fixation of the butterfly valve 5 are realized, the butterfly valve 5 is suspended between the first support base 3 and the second support base 4, so that the two groups of support bases can provide stable support for the butterfly valve 5, ensure that the butterfly valve maintains the correct installation position and posture in the pipeline system, and the suspended butterfly valve 5 facilitates the interface connection of the pipeline.

[0035] When the butterfly valve 5 needs to be disassembled, the rotating disc 9 is reversely rotated, the lead screw 6 is reversely rotated, and the second support base 4 is driven to move away from the first support base 3 along the guide rod 8. When the clamping force between the second support base 4 and the butterfly valve 5 is released, the butterfly valve 5 can be easily taken out. In this process, the rollers 18 continue to play a role, reduce the friction force when the second support base 4 moves, and make the disassembly operation more smooth.

[0036] And in the butterfly valve 5 is installed, two groups of support rod 7 for the butterfly valve 5 provides the bottom support, support rod 7 bottom through the sliding block 14 in the sleeve 13 in the sliding slot 15 sliding connection, ensure the stability and adjustability of support rod 7, at the same time, the spring 16 makes the supporting pad 17 and butterfly valve 5 keep contact, can automatically adjust the supporting force according to the weight of butterfly valve 5 and the external force, make butterfly valve 5 always keep stable support state, and in the working process, the weight of butterfly valve 5 and the force of fluid on butterfly valve 5 through the first support seat 3, the second support seat 4 and support pad 17 transmission and dispersed to the installation floor 1 and base 2, ensure that the butterfly valve 5 in the running process will not be due to uneven force displacement or damage.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application have, and not for limiting the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
