crosswater shower valves
diverter valve shower
The following valve installation for you to explain the matters needing attention.
- 1. When installing the valve, clean the inner chamber and sealing surface, tighten the connecting bolts evenly, and check whether the packing is compressed;|
- 2. The international valve is installed in the closed position;
- 3. The valve should be installed in the allowed position, but should pay attention to the convenience of maintenance and operation;
- 4. The installation of the globe valve should make the flow direction of the medium consistent with the arrow marked on the valve body. For the valve that is not often opened and closed and needs to strictly ensure no leakage in the closed state, it can be reverse installed to make it closed with the help of the medium pressure;
- 5. When tightening the compression screw, the valve should be in a slightly open state to avoid crushing the top sealing surface of the valve;
- 6. Before positioning the cryogenic valve should try its best to do the opening and closing test in the cold state;
- 7. Large air separation tower in the naked cold, in the cold state of the connection valve flange pre-tightening, to prevent leakage at room temperature and low temperature leakage phenomenon;
- 8. After all the valves are in place, they should be opened and closed again. It is qualified that there is no jamming;
- 9. When the new valve is used, the packing should not be pressed too tightly, so as not to leak too much, lest the valve stem is pressed too much, accelerate wear and tear, and open and close laboriously;
