Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as Figure 1-5 As shown, the double-seal leak-free high-efficiency air supply port of the present invention includes a box shell 1 communicated with the air supply duct, a support ring 2 fixedly arranged in the box shell, and a pressure ring 3 fixedly connected to the support ring. And the high-efficiency filter 4, wherein, the support ring 2 includes an outer side 21 fixedly connected with the box shell, an upper positioning side 22 extending vertically inwardly relative to the top of the outer side, and an integrally formed bottom of the outer side "7" shaped outer positioning edge 24, and the zero-pressure chamber 23 formed below the upper positioning edge on the inner...

The invention discloses a double-seal leak-tightness efficient air supply outlet. The double-seal leak-tightness efficient air supply outlet comprises a box body housing communicated with an air supply duct, a supporting ring fixedly arranged in the box body housing, and a compression ring and an efficient filter which are fixedly connected with the supporting ring, wherein the supporting ring comprises a zero-pressure cavity; a plurality of leakage collection holes distributed at intervals are formed on the inner side face of the zero-pressure cavity; at least one pressure relief hole is arranged on the outer side face of the zero-pressure cavity; and the efficient filter is positioned between an upper positioning side and the compression ring. According to the double-seal leak-tightness efficient air supply outlet, a sealing device is added and leaked dust-containing gas is discharged outwards after being depressurized step by step, so that a small internal pressure difference of the box body housing and the cavity between the supporting ring and the efficient filter is guaranteed, a further leakage can be effectively inhibited, pressure in the cavity can be gradually released so as to avoid causing sealing pressure to a second sealing ring and a third sealing ring, and meanwhile the supply air is stopped from losing too much, and total supply air is guaranteed.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to a double-sealed non-leakage high-efficiency air supply port. Background technique [0002] The high-efficiency air supply port is an ideal terminal filter device for 1,000-class, 100,000-class purification air-conditioning systems, and can be widely used in purification air-conditioning systems in medicine, sanitation, electronics, and chemical industries. The high-efficiency air supply port is used as a terminal filter device for the renovation and construction of clean rooms of 1000-300000 levels at all levels, and is the key equipment to meet the purification requirements. The high-efficiency air supply port includes a static pressure box, a diffuser plate, and a high-efficiency filter. The interface with the air duct can be top or side connection. [0003] However, the high-efficiency air supply port in the existing purification air conditioning system and the seali...
