Detailed Description
To make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly and completely describe the technical solutions with reference to the drawings and embodiments of the present invention, but the scope of the present invention is not limited to the following description.
The utility model provides an auxiliary device that butt clamp formula turbine flowmeter installation was dismantled, including pipeline 3, middle fracture department is provided with flowmeter 1 on the pipeline 3, flowmeter 1 both ends are connected through first mounting flange 2 with pipeline 3, and fix through fixing bolt 4 and fixation nut 5, fixed second mounting flange 9 that is equipped with on the 2 outside pipelines 3 of first mounting flange, can dismantle between two second mounting flanges 9 and be equipped with second clamping screw 8, through the method that uses second clamping screw 8 to fix, can ensure the axiality of pipeline 3 and measuring accuracy, can dismantle between two first mounting flanges 2 and be equipped with first clamping screw 7, through the method that uses first clamping screw 7 to fix, can play the supporting role to flowmeter 1. First clamping screw 7 and second clamping screw 8 are two at least, easy operation is light, safety and reliability, 9 diameters of second clamping flange are longer than 2 diameters of first clamping flange, thus can not influence the installation of flowmeter 1, still can prevent pipeline 3 from taking place the skew when changing flowmeter 1, first clamping screw 7 and second clamping screw 8 all are equipped with fixation nut 5, use fixation nut 5 to carry out spacing fixed to fixation screw, can be more firm reliable, still be equipped with sealed 6 between flowmeter 1 and the first clamping flange 2, can make the leakproofness between flowmeter 1 and the pipeline 3 better, thereby prevent to leak.
When the flowmeter 1 is disassembled: firstly, two second fixing screws 8 are respectively inserted from the outer side of a second fixing flange 9 on one side of the pipeline 3 at vertically symmetrical positions, penetrate through the inner side of the second fixing flange 9 on the other side and penetrate out of the inner side of the second fixing flange 9 on the other side, fixing nuts 5 are respectively screwed to the positions where the second fixing screws 8 penetrate in and penetrate out, the fixing nuts 5 at the positions where the second fixing screws 8 penetrate out are respectively fastened by using a wrench, the coaxiality and the measurement accuracy of the pipeline 3 can be ensured by fixing the two second fixing screws 8, and the pipeline 3 can be prevented from shifting; then, the fixing bolts 4 and the fixing nuts 5 connected with the flowmeter 1 and the first fixing flange 2 are unscrewed by a spanner, the unscrewing length on the two sides is 25mm, then the fixing bolts 4 and the fixing nuts 5 on the left side and the right side are dismantled, then two first fixing screws 7 are respectively inserted from the outer side of the first fixing flange 2 on one side of the pipeline 3 and penetrate out from the inner side of the first fixing flange 2 on the other side at positions which are symmetrical up and down, the fixing nuts 5 are respectively screwed to the penetrating and penetrating positions, the fixing nuts 5 at the penetrating and penetrating positions of the first fixing screws 7 are respectively fastened by the spanner, and the two first fixing screws 7 play a role in supporting and assisting in fixing the flowmeter 1; finally, the remaining fixing bolts 4 and fixing nuts 5 connecting the flowmeter 1 and the first fixing flange 2 are removed, and the flowmeter 1 can be taken out in the horizontal direction.
When the flowmeter 1 is installed: at first, the integrity of the sealing gasket 6 is checked, if abnormal conditions exist, the sealing gasket should be immediately replaced, so as not to affect the sealing performance, the positions of the first fixing screw rod 7 and the second fixing screw rod 8 are kept unchanged when the flowmeter 1 is disassembled, the flow direction of a medium in the pipeline 3 is adjusted according to the size when the flowmeter 1 is disassembled, the flowmeter 1 is horizontally placed between the first fixing flanges 2 at the middle fracture of the pipeline 3, and the first fixing screw rod 7 plays a limiting role below the flowmeter 1, so the flowmeter 1 is firmly blocked and cannot fall.
