Third, the installation dimensions
1. The structure form

2. Simple meter installation method
• meet the meter straight pipe section on the installation point requires an open circle Φ100 lack of.
• Use Φ109 * a good start on the opening round at the lack of welded pipe and pipe 4.5mm base, rear base of weld visually no obvious skew.
• The speed probe into the pipe, adjusting the depth of insertion so that the center axis of the probe and the pipe think fit, and the angle between the probe centerline axis of the pipeline should not exceed 5 degrees, and then adjust the standard so that the fluid flows the same flow.
• The ball valves and flange or butt welded base with bolt well.
3. Ball flowmeter (cut-off valve type) installation and removal methods
• skills requirement
1. No note dimensions and materials by the user according to their own determination compressive strength and corrosion requirements.
2. Install base 'position on the pipeline should be correct, there should be no significant deviation intuitive.
3. Non-steel pipe clamp available fixed 'installed base', but there must be void size shown in the clip on 85mm, so
Thus the gap penetrating ball screws when installing the M16 * 65.
4. Standard connection flange dimensions: GB4216.4-84.

• installation steps
When first installed; if the test pipe allow disconnection; schematic installation in accordance with the base (Fig. 3), in the pipeline to meet the position of the measured length of straight pipe required to open a hole Φ100 complete 'installation base' and connection pipe. Then follow the installation diagram (Figure 2) to complete all the installation work can also be installed temporarily closed ball after ball, so as not to affect the piped fluid, to be later installed sensors.
When first installed; if the test does not allow drying pipeline; in the case of the pipeline can not yet opening; first complete 'installation base (Fig. 3) on the pipe is fixed and sealed, and then install the ball valve, and then use After non-stop water drilling machine drilling drilling, remove non-stop water drilling machine, install the sensor; or removing the non-stop water drilling machine, temporarily close the ball valve to be installed after the sensor off the water drill. Installation and removal method on the ball with the installation and removal methods sensor is basically the same, not in this otherwise.
Note ①: Before installing the valve, you must check valve, should be fully open and fully closed by the valve must be fully open to fully closed, then from fully closed to fully open when the ball valve stopper piece from the closed position to the full. When fully open position, the valve must be in the fully open state, or should stop dressing sheet.
Note ②: When installing ball, 'installed base' on the longer end of the pipe connection.
