Description

Technical Field

[0001] The utility model relates to the technical field of valve installation support, in particular to a support for a pipeline valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium.

[0003] Pipeline valves are generally connected to pipelines through flanges. When installing some larger valves, if the bottom of the valve is in an unsupported state for a long time, the pipeline valve is likely to cause gravity load on the flange at the connection under the action of its own gravity, which may easily cause the valve connection to be deformed under stress and cause leakage at the connection. Based on this, a bracket for pipeline valves is provided. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 3 In the embodiment of the present invention, a bracket for a pipeline valve includes a support assembly 1 consisting of a casting box 101, a fixing column 102, a support screw 105, an arc-shaped support seat 106, and an adjusting nut 107. The fixing column 102 is fixed to the middle part of the inner side of the casting box 101, and a plurality of reinforcing plates 103 are welded and fixedly connected between the outer side of the bottom of the fixing column 102 and the casting box 101. A lifting hole groove 104 is opened on the top of the fixing column 102, and the support screw 105 is inserted into the inner side of the lifting hole groove 104. The adjusting nut 107 is threadedly connected to the outer side of the support screw 105 and fits the top of the fixing column 102. The arc-shaped support seat 106 is fixed to the top of the support screw 105, and is used to support the connecting flange of the pipeline valve through the arc-shaped support seat 106. A limited clamping assembly 2 is provided on the outer side of the fixing column 102 and the arc-shaped support seat 106. The limited clamping assembly 2 is used to realize the connection and fixation of the arc-shaped support seat 106 and the connecting flange.

[0027] The limiting clamping assembly 2 includes a fixing unit and a vertical limiting unit;

[0028] The fixing unit cooperates with the arc-shaped support seat 106 to wrap and clamp the connecting flange;

[0029] The vertical limiting unit is used to limit the vertical height of the fixing unit and the arc-shaped support seat 106, thereby achieving stable support for the connecting flange;

[0030] The fixing unit includes an L-shaped arm 201, an arc-shaped clamping block 202, and a semicircular clamp 203;

[0031] The arc-shaped clamp block 202 is fixed to the top of the vertical portion of the L-shaped arm 201, and the semicircular clamp 203 is fixed to one side of the horizontal portion of the L-shaped arm 201;

[0032] The arc-shaped support base 106 has docking grooves 108 on both side edges;

[0033] The fixing units are symmetrically arranged in two groups. The two arc-shaped clamping blocks 202 in the two groups of fixing units are spliced ​​together with the arc-shaped support seat 106 to form an annular structure, which is used to wrap and clamp the connecting flange.

[0034] The two semicircular clamps 203 in the two sets of fixing units are sleeved on the outside of the fixing column 102, and the two semicircular clamps 203 are fixed by bolts to achieve the connection and fixation of the two sets of fixing units and the fixing column 102;

[0035] The vertical limiting unit includes a limiting block 204 and a limiting nut 205;

[0036] The limit block 204 is fixed to the vertical portion of the L-shaped arm 201 near the top. When the L-shaped arm 201 is clamped to the inner side of the docking groove 108, the limit block 204 is attached to the bottom edge of the arc-shaped support seat 106, so as to realize the relative limitation of the vertical direction between the L-shaped arm 201 and the arc-shaped support seat 106.

[0037] The outer side of the fixing column 102 is formed with an external thread 109, and two limiting nuts 205 are provided. The two limiting nuts 205 are threadedly connected to the outer side of the fixing column 102. The two limiting nuts 205 are tightly fitted with the upper and lower ends of the semicircular clamp 203 to achieve relative positioning of the semicircular clamp 203 and the fixing column 102 in the vertical direction;

[0038] The outer wall size of the vertical portion of the L-shaped arm 201 matches the inner wall size of the docking groove 108 , and the inner sides of the arc-shaped support seat 106 , the arc-shaped clamping block 202 , and the semicircular clamp 203 are all glued and fixed with a rubber layer.

[0039] In this embodiment, when using this bracket, the operating steps are as follows:

[0040] First, the support assembly 1 is moved as a whole to the position to be supported. Then, the height of the arc-shaped support seat 106 can be adjusted according to the height of the connecting flange to be supported. The support screw 105 can be held by hand to rotate the adjusting nut 107 (or the adjusting nut 107 can be held by hand to rotate the support screw 105) to adjust the height of the support screw 105 protruding from the fixed column 102, thereby achieving the height adjustment of the arc-shaped support seat 106;

[0041] When the bottom of the arc-shaped support seat 106 contacts the bottom of the connecting flange, the adjustment can be stopped. Then, two sets of limit clamping components 2 are taken out and inserted into the docking groove 108 through the vertical part of the L-shaped arm 201. The limit block 204 is attached to the bottom edge of the arc-shaped support seat 106. Finally, the two arc clamping blocks 202 are docked with each other and sleeved on the upper part of the connecting flange to wrap the connecting flange.

[0042] At the same time, the two semicircular clamps 203 are sleeved on the outside of the fixing column 102, and then the two semicircular clamps 203 are fixed by bolts and nuts, so that the two semicircular clamps 203 are tightly fitted to the outside of the fixing column 102 (it should be noted that corresponding through holes are opened on the semicircular clamps 203 for the bolts to pass through). In this way, not only the arc-shaped support seat 106 and the arc-shaped clamping block 202 are clamped on the connecting flange, but also the height of the arc-shaped support seat 106 is fixed.

[0043] Then, the upper and lower limiting nuts 205 are screwed to fit the upper and lower ends of the semicircular clamp 203 respectively, thereby further fixing the height of the arc-shaped support seat 106;

[0044] Finally, concrete can be poured inside the pouring box 101 to increase the overall weight of the device so that the device as a whole remains stable.

[0045] By cooperating with the above multiple parts, stable support can be achieved for the connecting flange of the valve, and by setting the limiting clamping assembly 2, the final fastening position of the device can be in a lower state, so that the fastening operation can be performed more conveniently. At the same time, the structural setting of the limiting nut 205 can prevent the arc-shaped support seat 106 from loosening, effectively improving the stability of the device.

[0046] Please refer to Figures 1 to 3 , the bottom level of the external thread 109 is higher than the top level of the casting box 101.

[0047] In this embodiment, when pouring concrete inside the pouring box 101 , the concrete will not come into contact with the external thread 109 , thereby ensuring the stable use function of the limiting nut 205 .

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
