英文產品介紹：
Manhole is installed in the tank on top of the safety of emergency ventilation devices, usually associated with fire, mechanical breathing valve supporting the use of, both to avoid due to the causes of accidents caused by tank sharp overpressure or vacuum damaged tanks and accidents, but also With constant pressure discharge, constant pressure inhalation, opening and closing a flexible, safe fire retardant, compact structure, good sealing performance, safety and reliability advantages.
Manhole into emergency relief manhole explosion-proof fire retardant breathing manhole, tank top manhole, the manhole of the tank wall and with a core manhole. The diameter of the manhole and manhole center from the floor size of manhole has been molding products, diameter usually 600mm. Manhole center from the floor general for the 750mm. To facilitate staff in the installation, cleaning, maintenance and out of the tank and ventilation.
Non-metallic tank manhole located in the tank on top of the metal tank manhole located in the tank wall to the next circle board. Most of the 600mm diameter hole at its center from the base plate 750mm, tank cleaning or maintenance personnel in and out of the tank, also known as the door. Maintenance clean up the tank moment manhole, light and ventilation. Vertical tank capacity of less than 5000m ³ set 1-2 hole, 5000m ³ above located two holes. The installation of the manhole with access to the oil pipeline at intervals of not more than 90 °. When only set up a manhole, it should be placed in a tank top, light transmission hole opposite; when set up two individual holes, one located at the opposite of light transmission hole, the other should be at least 90 ° apart with the first individual hole .
Manhole should be one in and out near the pipeline right side and try to make the holes are confined to the tank room door, so that personnel access, and maintenance of tanks and ventilation to take over.
Manhole is installed in the tank of the lowest body ring, anti-leakage is particularly important. Asked the two flange joint surface must ensure that its flatness, no floating twist phenomenon. Strengthen the board and the flange should be cut without stitching on the block plate. On the processing of the flange and the cover ring, pay special attention to protection during construction. Sealing rubber gaskets 3mm thick asbestos, not allowed to have fractured. Install the manhole cover bolt, diagonally and force, to prevent the hole cover deformation. A manhole kind of division of a communication pipe capacity divided
The Wenzhou the Dekang professional production of sanitary grade manhole, stainless steel manhole, atmospheric hole, the pressure hole, oval hole, square hole, please contact us.
Manhole can accommodate specifications for a wide 360mm high 250mm (standard tin pore diameter 90mm cement pipe blocks, pipe section referred to as the standard block) the number of tube block or single-hole pipe pore diameter 90 mm, divided into large, and small
Stainless steel manhole
hree categories. Concrete shown in Table 1.

Communication pipeline set the size of the manhole, and should set long-term capacity of the communication pipe. Should not only consider the current construction communications pipeline capacity.
2, man-hole leading to the division of
Straight-through manhole manhole leading to the division can be divided into three links manhole Stone manholes and oblique Walter Kong, specifically detailed in the table below. Among them, the oblique Walter Kong is divided into 15 °, 30 °, 45 °, 60 °, 75 ° a total of five. Each oblique Walter Kong's point of view, applicable to within ± 7.5 °.
To the manhole cover to bear the load capacity is divided
Withstand the load capacity can be divided into installation and maintenance of steam -20 and steam -10 two kinds of people hole manhole cover, manhole manhole under a lot of fluid pressure in the tank the lower part, in order to prevent infiltration leakage, the quality of the installation of the manhole must be strict. On the processing of the flange and the cover sealed waterline in the construction, we need to protect, in order to avoid the use of oil leakage. Do mark each manhole removed, so as not loaded when the dislocation, affecting rigor. Install the nut on the manhole cover, to be paired diagonal evenly, to prevent the cover deformation or uneven force caused by oil leakage.
