Description
Technical field
The utility model relates to ultraviolet plumbing sterilization field, especially a kind of underwater sealing structure of ultraviolet lamp tube.
Background technology
Often need be immersed in the water at ultraviolet plumbing sterilisation system medium ultraviolet fluorescent tube, this just requires ultraviolet lamp tube in use to have good sealing property, can strict avoid the seepage of water.The existing fluorescent tube tightness system (shown in Figure 2) and the patent No. are that the fluorescent tube tightness system (shown in Figure 3) of ZL01244669.8 substantially all is made up of glass bushing strongback, sealing connection, sealing nut and gasket seal.As shown in Figure 2, stainless material is adopted in the sealing of glass bushing in the fluorescent tube tightness system, thereby causes glass bushing to break easily during the sealing extruding; Though the fluorescent tube tightness system among Fig. 3 is considered this problem, elastomeric material is adopted in the sealing of glass bushing, can avoid pushing glass bushing well; Yet these two fluorescent tube tightness systems are not all considered the sealing problem of the required feed cable of fluorescent tube.
The sealing nut of above-mentioned fluorescent tube tightness system is positioned at the glass bushing end, and the glass bushing end is fixed on the framework and is formed modular structure in the practical application, and sealing nut is positioned at the glass bushing end and certain-length is arranged, and outwards winding and to tighten sealing nut very inconvenient.These two fluorescent tube tightness systems are all very inconvenient in engineering is used, and do not reach safe and reliable requirement.
Summary of the invention
The utility model provides a kind of underwater sealing structure of ultraviolet lamp tube, and this underwater sealing structure is convenient for installation and maintenance, can reduce the breakage rate of glass bushing greatly.
The underwater sealing structure of the ultraviolet lamp tube in the utility model has following three advantages.
1, employing is multi-sealed, can avoid the seepage of water, reaches safe and reliable requirement;
2, realize the sealing of feed cable well, realize the insulating requirements of cable;
3, ultraviolet lamp tube is simple in structure, installation, dismounting, easy to maintenance.
The underwater sealing structure of the ultraviolet lamp tube in the utility model comprises cable, stainless steel frame, rubber internal connection, stainless steel sleeve pipe cap, stainless steel sleeve pipe nut, rubber cradle, tube plug, glass bushing and ultraviolet lamp tube.The cable of the required power supply of ultraviolet lamp tube is embedded in the rubber internal connection, can be connected with tube plug; The rubber internal connection is fixed in the stainless steel sleeve pipe cap, and glass bushing inserts in the stainless steel sleeve pipe cap, and positions by the rubber internal connection; Stainless steel sleeve pipe nut is closely connected by screw thread and stainless steel sleeve pipe cap, and rubber cradle is embedded in the groove of stainless steel sleeve pipe cap.Rubber internal connection, stainless steel sleeve pipe cap, stainless steel sleeve pipe nut closely contact cooperation with rubber cradle, can realize the sealing property of ultraviolet lamp tube, avoid the seepage of water.
The rubber internal connection accurately is arranged on stainless steel sleeve pipe cap inside by internal connection barb, internal connection circular protrusion and internal connection boss, can realize multiple leakproof.The rubber internal connection is provided with the internal connection outside screw, and internal connection boss, internal connection outside screw and rubber cradle seal glass bushing and be positioned in the stainless steel sleeve pipe cap.Be provided with cavity between rubber internal connection and the glass bushing, leave the space for the extruding of rubber internal connection on the one hand, the cavity after the extruding has pressure in addition, can prevent the seepage of sealing.
The stainless steel sleeve pipe cap is a cup-shaped, and a sidecar of the stainless steel sleeve pipe cap of close ultraviolet lamp tube has casing drive head outside screw and annular recess, can place rubber cradle in the annular recess.End car away from the stainless steel sleeve pipe nut of ultraviolet lamp tube has the nut internal thread, and casing drive head outside screw and nut internal thread closely cooperate during installation.
Mechanically resistant materials such as glass bushing discord stainless steel directly contact, and contact with the flexible material of this good springiness of rubber, and the rubber internal connection is fixed in the stainless steel sleeve pipe cap dexterously, and glass bushing takes place damaged in the time of can effectively preventing to install.The tube plug of ultraviolet lamp tube is embedded in the rubber internal connection, can realize watertight effect.
After rubber internal connection in the utility model structure and stainless steel sleeve pipe are fixing, weld together with external frame, cable also is placed in the framework, has avoided cable to be exposed to phenomenon in the water fully.
When ultraviolet lamp tube is installed, in the glass bushing of earlier ultraviolet lamp tube being packed into, glass bushing is packed in the stainless steel sleeve pipe cap, put and put well rubber cradle, tube plug is connected near the cable simultaneously; On the casing drive head outside screw of stainless steel sleeve pipe cap outside, tighten stainless steel sleeve pipe nut, sealed structure installation then.
When safeguarding ultraviolet lamp tube, the stainless steel sleeve pipe nut of only need outwarding winding is extracted glass bushing and ultraviolet lamp tube out and is got final product.
