Abstract
The utility model discloses a seal device for sealing the joints of the wall and wires passing through the wall when a room needs to be airtight. The seal device is achieved through the following technical proposal, the seal device consists of a stainless steel electric box, a stainless steel square tube for wires to be passed through, an aviation connector, wires and a waterproof connector. The stainless steel electric box is welded on the stainless steel plate of the main wall of a building; the stainless steel square tube is welded on the stainless steel electric box which is provided with a waterproof socket; the aviation connector is connected with the stainless steel square tube through a seal cushion. The waterproof socket is connected with the inner end of the aviation socket through the wire; and the outer end of the aviation socket is connected with an outdoor power supply. The joints of the parts of the seal device are very airtight, thus ensuring that the wires are passed through the wall safely without leakage. The seal device can meet the requirement of fumigation of strong oxidizing disinfectors, which is very beautiful in appearance, simple in structure, installed and used conveniently.
Description
Technical field
The utility model relates to electric wire field of sealing technology through walls, and in particular, relating to a kind ofly has under the situation that tightness requires indoor, can guarantee the device that indoor and outdoor electric wire threading place and building enclosure seal.
Background technique
According to domestic and international standards and norms, high-level laboratories such as numerous environmental chambers that are similar to the research volatile matter, bio-safety three, level Four laboratory require that the close property of building enclosure is good, intensity is high, corrosion-resistant; Inside needs to satisfy suppress requirement, the pressure decay meets " the laboratory biosafetyguidelines " (3rd edition 2004, health canada) about the regulation of leakproofness between the BSL-4 laboratory experiment, be that the laboratory is suppressed to 500pa, require internal pressure decay in 20 minutes to be not more than 50%.For reaching pressure decay index request, the various parts of inside, laboratory all will satisfy the tightness requirement, therefore how to solve the airtight problem of inlet wire of the electrical equipment of inside, laboratory, become one of key link in design, the construction.The present sealing means that adopts sealer usually, sealer is aging easily on the one hand, and sealer is difficult to bear the corrosion of long-term formaldehyde fumigation on the other hand, causes the laboratory to be built up and just occurs the threading leakage in the very short time, and the laboratory is difficult to satisfy sealing requirements.
The model utility content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and providing a kind of has under the situation that tightness requires indoor, can guarantee the electric wire that seals seal arrangement through walls.
The utility model electric wire seal arrangement through walls is achieved by following technical proposals, is made up of stainless steel square tube, aviation plug-in unit, electric wire, the waterproof socket of stainless steel electric box, threading; The stainless steel electric box is welded on the building main wall body corrosion resistant plate, the stainless steel square tube is welded on the stainless steel electric box, waterproof socket is installed on electric box, the aviation plug-in unit is connected with the stainless steel square tube by airtight rubber cushion, waterproof socket is connected aviation plug-in unit outer end junction chamber external power by electric wire and aviation plug-in unit are inner.
The utlity model has following beneficial effect: aviation plug-in unit, connection square tube, internal cable, electric box, inner building enclosure welding one, airtight nothing is revealed, and satisfies the inside threading and the consumer requirement that have tightness to require the room.Each constituent element joint tightness height guarantees the safety nothing leakage that electric wire is through walls; Can satisfy the stifling requirement of strong oxidizing property disinfector; Overall appearance is attractive in appearance, and is simple in structure, easy to install.
Description of drawings
Fig. 1 is electric box of the present utility model and wallboard connection diagram;
Fig. 2 is square tube of the present utility model and electric box connection diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is made up of stainless steel square tube, aviation plug-in unit, electric wire, the waterproof socket of stainless steel electric box, threading; As shown in Figure 1, stainless steel electric box 3 is welded on the corrosion resistant plate 2 of building main wall body 1; As shown in Figure 2, stainless steel square tube 8 is passed building main wall body and is welded on stainless steel electric box 3 inner side surfaces, and waterproof socket 4 is installed on the electric box outer side surface; Aviation plug-in unit 11 is connected with the stainless steel square tube by airtight rubber cushion, and waterproof socket is connected aviation plug-in unit outer end junction chamber external power by electric wire 10 and aviation plug-in unit are inner.
Each several part structure and mounting type are as follows:
(1) mounting structure of electric box.Lay or pre-buried corrosion resistant plate on building main wall body, guarantee the airtight nothing leakage of building enclosure, in the electric box welding and corrosion resistant plate with stainless steel, waterproof socket is installed in perforate on electric box.
(2) threading stainless steel square pipe connecting structure.On building enclosure and stainless steel electric box, open the hole onesize with square tube, to place wherein with the stainless steel square tube that can pass the design wire thicknesses, adopt stainless steel full weld technology between square tube and the electric box, square tube the other end soldering stainless steel flange, square tube inside are provided with to be used and the electric wire that is connected waterproof socket and aviation plug-in unit.
(3) line equipment structure.By the flange of square tube one end and the flange of aviation plug-in unit, utilize nut, screw and airtight rubber pad, the aviation plug-in unit is connected one with square tube, the electric wire soldering is an one in the wire terminal of aviation plug-in unit one end and the square tube, another termination external power supply of aviation plug-in unit.
Claims (2)
1. an electric wire seal arrangement through walls is characterized in that, is made up of stainless steel square tube, aviation plug-in unit, electric wire, the waterproof socket of stainless steel electric box, threading; The stainless steel electric box is welded on the building main wall body corrosion resistant plate, the stainless steel square tube is welded on the stainless steel electric box, waterproof socket is installed on electric box, the aviation plug-in unit is connected with the stainless steel square tube by airtight rubber cushion, waterproof socket is connected aviation plug-in unit outer end junction chamber external power by electric wire and aviation plug-in unit are inner.
