High-efficiency air supply outlet and air valve installation in purification workshop
In the construction of the purification workshop, the installation and construction of the air outlet and the air valve are very important. The professional responsible personnel of Zhongjing Global purification will summarize the relevant issues for your reference and reference. The air vents are generally laid on the ceiling and the wall. The installation of various air vents should be horizontal, vertical, firm, tight, and the surface should be flat. The exposed part should be parallel to the indoor lines; most air vents are adjustable, and some are even rotatable. Yes, all tuyere with adjustable and rotating parts must ensure that the movable parts are light and flexible, the blades are straight, and there should be no rubbing with the frame; The four corners are square. For the circular tuyere, its diameter should be controlled. Generally, any two of them are perpendicular to each other, so that the deviation between the two should not be greater than 2mm, so that basically no elliptical shape will appear; the same type of tuyere installed indoors should be symmetrical. Distribution, so that the air outlet is kept neatly indoors, the air outlet of the same wind direction, the adjustment device should be on the same side; the air blowing angle of the high-efficiency air supply outlet should be adjusted according to the air flow organization; the surface of the air outlet should be flat, beautiful, and design The allowable deviation of the size should not be greater than 2mm. In the whole air conditioning system, the air outlet is a part exposed in the room, so its shape is required to be higher.
Installation of rectangular linkage adjustable louver tuyere in purification pharmaceutical cleanroom: when the tuyere is connected to the air duct, cut out a 10mm connection tenon at the part of the air duct extending from the wall according to the position and size of the strip hole in the outer frame of the valve, and then install the valve Install the frame, and then install the blade frame; when installing the air outlet with the air volume control valve, install the control valve frame first, and then install the blade frame of the air outlet; when installing the air outlet without the air volume control valve, it should be installed in the air duct or a reserved hole On the inner frame, use riveting or tighten the angular connection clip, and then install the blade frame; when the air outlet is directly fixed on the reserved hole, the valve frame should be placed in the hole, and wood screws should be used to pass through the small holes on the four walls of the valve frame. , tighten it on the reserved wooden tenon or wooden frame, and then install the blade frame. When the blade frame is installed, the screwdriver should be inserted between the blades to tighten the screws, and the pressing frame should be fixed on the connecting clip on the inner wall of the valve frame. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for purification workshops and laboratories.
The installation of the air valve is the same as the installation of the air duct. Before installation, check whether the frame structure is firm, and adjust the braking, positioning and other devices accurately and flexibly. When installing, align the flange of the air valve with the flange of the air duct or equipment. Positive, and tighten the screws on the sealing heat sheet to make the connection firm and tight; pay attention to the airflow direction of the air valve, and install it according to the standard direction of the air valve shell. There are obvious signs on the valve body; the check valve should be installed on the outlet pipe section of the fan, the opening direction must be consistent with the airflow direction, the valve shaft of the check valve must be flexible, the valve plate should be closed tightly, and the hinge and rotating shaft should be made of materials that are not easy to corrode. The air duct for conveying dust and dust should not use butterfly valve, but a closed oblique flapper valve. The oblique flapper valve of the dust removal system should be installed in a place where no dust accumulates; It should be against the airflow direction; when installing the horizontal air duct, the plug board should be installed along the airflow; the residual pressure valve should be installed under the wall of the purification workshop, and ensure the tightness of the valve body and the wall after connecting, and pay attention to the position of the valve plate in the purification workshop. After the air valve is installed, the direction of opening and closing and the degree of opening should be marked on the outside of the valve body. For the convenience of debugging and management of the thermal insulation system, it should be marked on the outside of the thermal insulation layer.
