I. Inspection during construction

For those processes that will have a serious impact on the entire process if the construction fails, it must be checked after it is completed. Such as kitchen and bathroom waterproof, buried underground water and electricity pipelines, after the construction of the floor tiles found that water is not qualified, the wiring pipeline is not connected, plumbing pipeline is not connected or water leakage, it can only be reworked.

Second, inspection

1. The wire conduit should be unblocked, and the conduit wire should be drawn back and forth by hand. It should be able to twitch so that the damaged wire can be replaced later.

2. Check the socket wire sequence with the electric pen or socket detector. It must be left zero and right fire on the ground.

3. Check the switch wire sequence with the electric pen. The switch must control the fire wire.

4. Check the test button of the leakage protector or check the leakage protector with the socket detector. The operation must be flexible.

5, using the insulation resistance meter to detect the insulation resistance of the loop is not less than 0.5M ohms.

6, open the main valve, hand touch to the drainage pipe joints to be tight, no water leakage, drainage should be smooth.

Acceptance inspection must pay attention to the preservation of the water circuit construction drawings, and require the drawings and the actual to be consistent with each other, because the drawings are the basis for future maintenance, but now most owners ignore this.

Globe Valve

The globe valve is used to cut off the flow of the medium. The globe valve is suitable for frequently opened occasions. The sealing parts of the globe valve are the disc and the valve seat. In order to make the globe valve close tightly, the mating surface of the disc and the valve seat should be grinding or using gaskets. The sealing surface can also be inset with bronze, stainless steel and other corrosion-resistant and wear-resistant materials. The disc and stem of the globe valve are connected with each other, so that the disc and stem are closely fitted. The lifting of the disc of the globe valve is generally controlled by the stem. The upper part of the stem of the globe valve is the handwheel, and the middle part is the thread and packing sealing section. The role of the packing is to prevent the internal medium of the valve body from leaking along the stem.
