1. When the valve is turned off to the engineering port pipe and an accessory, 23 mm thick steel sheet welding should be used. The weld should be sufficient, uniform, tight.

2. Ventilation pipes in the pollution region should be welded. The ventilation tube and the shutoff valve should be connected to the flange with the sealing groove, and the contact should be flat. The flange gasket should be a complete ring, no interface rubber seal.

3. The thickness of the steel plate of the main engineering ventilation pipe and the attachment should meet the design requirements. When the design is not required. The thickness of the steel sheet should be greater than 0.75 mm.

4. The engineering pressure measuring tube is provided with a downward elbow at one end outside the airtight protective door, and the other end is disposed in a ventilation chamber or a control chamber and a ball valve is installed. The pressure gauge interface through the gas passage should be welded.

5. The measurement hole and cleaning sampling tube of the ventilator should be simultaneously produced at the same time. The measurement holes and eluent sampling tubes should be blocked.

6. The air flow direction of the ventilator, the opening and closing direction and opening of the valve should be clearly marked.

Exhaust pipe and accessories installation

Air-conditioned pipeline

1. The tobacco pipe should be a steel pipe or cast iron tube. When the welding steel pipe is used, the wall thickness should be greater than 3 mm; the pipe joint should be welded. When using the flange connection, the surface of the flange should be flat and should have a sealing tank; a heat-resistant rubber pad should be added between the flanges.

2. Cast iron exhaust pipe buried in concrete should be connected to the flange.

3. The exhaustible pipe should be installed along the shaft. The unidirectional sleeve telescopic should be concentric with the front and rear tobacco pipes. The connection between the diesel exhaust pipe and the exhaust pipe should have a buffer facility.

4. The installation of the exhaust pipe should meet the following requirements:

(1) The slope of the elder should be 0.5, and the water valve should be located at a low point;

(2) The cleaning hole baffle should be heat-resistant and should be firmly fixed;

(3) When the exhaust pipe passes through the wall, the gap around it should be filled with a stone cotton rope;

(4) The connection between the exhaust pipe and the exhaust pipe should be embedded with a sealed short tube, the short tube should pass through the wall and should have a flange and a sealed wing ring.

(5) The ground exit of the exhaust pipe should be provided with a rain cap, and measures should be taken to prevent the exhaust pipe from being blocked at 150200 mm from the ground.

Equipment installation engineering acceptance

Ventilation system tests should meet the following requirements:

1. The airtight test airtight test is to seal the pipeline and close the valve, and the inflation pressure is 5.06 × 104 Pa, sealed for 5 min.

2. The airtight test of the filtration absorption tower indicates that the pressure drop in 5 minutes after the pressure is 1.06 × 104Pa is no greater than 660 Pa;

3. Ultra-pressure test of filters and ventilation projects should be 3050Pa;

4, cleaning, filter, isolation and ventilation mode switches between each other. Various ventilated portions, sent to, line,. Return low and stress meets design requirements; 5, the temperature and relative humidity of the main chain should meet general requirements.
