Description

Flange ball valve heightening support

Technical Field

The utility model relates to a heightening support, more specifically say, relate to a flange ball valve heightening support.

Background

The flange ball valve is applied to pipelines due to the existence of special working conditions, such as: low temperature, steam and the like, so the opening and closing control mechanism for controlling the opening and closing of the flange ball valve is required to be far away from special working conditions so as to avoid causing damage to human bodies. Most flange ball valves in the market are designed to be heightened at the beginning, but when some flange ball valves which are low platforms or are not high enough in height need to be heightened for operation, the whole flange ball valve needs to be replaced, so that the normal operation of a pipeline is influenced, the resource waste is easily caused, and the cost for replacing the whole valve is high.

Disclosure of Invention

Problem to exist among the prior art, the utility model aims to provide a flange ball valve increases support device, which comprises a bracket, add the long valve rod cover, add the long valve rod, the pad cover, hexagon socket head cap head screw, spacing piece, pad cover recess, open and close the axle, add the long valve rod cover and be ring shape, add long valve rod cover center and be circular through-hole, add the long valve rod cover and be used for installing the long valve rod, it is cylindrical to add the long valve rod, add the long valve rod and insert the long valve rod cover, add the long valve rod and weld through argon arc welding with the long valve rod cover, will add long valve rod and add long valve rod cover tightly to fix on flange ball valve rod through hexagon socket head cap head screw, it is not hard up.

After extension valve rod and extension valve rod cover and the fixed completion of flange ball valve rod, place the support on the flange ball valve disk seat, the support divide into two parts, the support left side is unanimous with the right side shape size structure, the support is the I shape, the support lower extreme is connected with flange ball valve disk seat, the support upper end is used for placing the axle of opening and close, the support is located the left and right sides of extension valve rod and extension valve rod cover respectively, the support will extend the valve rod and extend the valve rod cover encapsulation, the support passes through the nut bolt and is connected with flange ball valve disk seat, the processing of support upper end has the cover recess, cover recess is the rectangle, cover recess is used for the installation to cover the pad, covers the axle of opening and close, avoids opening and close the axle and take place the axial runout.

Compared with the prior art, the utility model has the advantages of: the utility model discloses can increase effectively the operating height of the start-stop control mechanism of the flange ball valve of having servings on the pipeline, the solution of low cost flange ball valve start-stop control mechanism operating height not enough problem under the special operating mode.
