Abstract
The invention provides an air tight junction box used for a biological clean safety laboratory. The gas tightness of a junction box body is good, and the gas tightness between the junction box body and the auxiliary pipe fitting is good. The junction box contains the junction box body. The air tight junction box of the invention is characterized in that a rifled pipe joint is arranged on the installation side of the auxiliary pipe fitting of the junction box body, and an air tight seal is arranged on the borders of the open side of the junction box body.
Description
(1) technical field
The present invention relates to the field of accessories of the installing engineering of biological clean safety laboratory, be specially the air tight junction box that biological clean safety laboratory uses.
(2) background technology
Clean rooms such as laboratory, operating room, vaccine workshop are more and more higher to the whole air-tightness requirement of building enclosure at present, and especially three-grade biological safety laboratory, the high influenza vaccines workshop of causing a disease etc. require high especially to the positive and negative pressure oriented flow of integral body.In order to guarantee the whole air-tightness of building enclosure, building enclosure is that the airtight processing of metal color steel and concealed installation equipment junction, electric pipe arrangement and terminal box junction just seems and is even more important.There is following shortcoming in the conventional mounting method of existing common PVC terminal box: (1) junction box body is non-hermetic, so can not guarantee the bubble-tight requirement of environment during construction and installation; (2) after the employing concealed installation construction method, junction box body and pipe arrangement pipe fitting can't be tightly connected, and can't guarantee bubble-tight requirement between box body panel and metal color steel.
(3) summary of the invention
At the problems referred to above, the invention provides the air tight junction box that biological clean safety laboratory uses, its junction box body air-tightness is good, junction box body and pipe arrangement pipe fitting air-tightness are good.
Its technical scheme is such: it comprises junction box body, it is characterized in that: the installation side of the pipe arrangement pipe fitting of described junction box body is equipped with female union, and air packing is installed on the edge part of the open-position-side of described junction box body.
It is further characterized in that: described junction box body adopts high-strength rigid to mould the PVC material by the casting method one-shot forming; Described female union is specially internal thread coating steel pipe straight joint, and it is embedded in the top of junction box body in advance.
After adopting said structure of the present invention, the pipe arrangement pipe fitting described female union that is threaded, the metal color steel is fastening to press-fit in described air packing, thereby arrives that the junction box body air-tightness is good, junction box body and pipe arrangement pipe fitting air-tightness be good.
(4) description of drawings
Fig. 1 is the structural representation of stereogram of the present invention;
Fig. 2 is the structural representation sketch of installment state of the present invention.
(5) embodiment
See Fig. 1, Fig. 2, the present invention includes junction box body, the installation side of the pipe arrangement pipe fitting of junction box body 1 is equipped with female union 2 top of junction box body 1 (among the Fig. 1), air packing 3 is installed on the edge part 4 of the open-position-side of junction box body 1, and junction box body 1 adopts high-strength rigid to mould the PVC material by the casting method one-shot forming.
Its mounting structure simplified schematic diagram is seen Fig. 2, the internal thread coating steel pipe straight joint 2 pipe arrangement pipe fitting 5 that is threaded, and metal color steel 6 is fastening to press-fit in air packing 3 rear threads and connects junction box body 1.
Claims (3)
