Abstract
The utility model discloses an ultraviolet lamp tube sealing device, comprising an ultraviolet lamp tube and ultraviolet lamp tube mounting bases arranged at two ends of the lamp tube, wherein the ultraviolet lamp tube is sleeved with a quartz socket tube, and the quartz socket tube is fixed on the mounting bases through fastening nuts; two ends of the ultraviolet lamp tube are sleeved with sleeve ceramic chamber linings and the ceramic chamber linings are sealed by glands; the glands are fixed on the fastening nuts through bolts or screws; a cable stuffing box is arranged at an open hole in the middle of each gland. The ultraviolet lamp tube sealing device disclosed by the utility model is simple in structure, and convenient to install, dismantle and replace. The replacement work of the cleaning machine can be achieved under the condition of not taking out the overall ultraviolet lamp tube sealing device, and water does not flow out from the sealing device to damage an electric system even if the quartz socket tube cracks, so that the safety of the overall system is ensured.
Description
Technical field
The utility model relates to a kind of tightness system, relates in particular to a kind of tightness system of ultraviolet lamp tube.
Background technology
In water body, contain various microorganisms, these microorganisms, because volume is little, quantity is many, are difficult to remove.Especially in the water ballast of boats and ships, the different biological groups that contain each marine site, if do not control the microorganism in water ballast, the strange land discharge of water ballast, damages ocean environment.With ultraviolet lamp tube, water ballast is carried out to sterilization simple, sterilization effect is good.But due to the sterilization of water ballast is carried out in water body, the sealing problem of ultraviolet lamp tube just becomes the current problem that must solve.Existing ultraviolet lamp tube tightness system is by ultraviolet lamp integral sealing, in the time cleaning and change ultraviolet lamp tube, whole device need to be taken out, just need during this period of time ultraviolet sterilization device out of service, this will affect the processing of water ballast, especially at ship undocking or in the time that boats and ships carry out loading and unloading operation etc., while being badly in need of water ballast to process, if ultraviolet sterilization device breaks down, can not guarantee the quality of ballast water body.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, install and change ultraviolet lamp tube tightness system easily, do not need whole ultraviolet sterilization device to take out and just can realize cleaning machine and more change jobs.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of ultraviolet lamp tube tightness system, comprise ultraviolet lamp tube and the ultraviolet lamp tube mount pad that is arranged on lamp tube ends, on described mount pad, there is outside screw, on fitting nut, there is identical with it internal thread, by fitting nut, the quartz socket tube outside ultraviolet lamp tube is fixed in described mount pad, quartz socket tube is closely connected with mount pad, and quartz socket tube is just isolated the water and the ultraviolet lamp tube that need sterilization completely like this.There is quartz socket tube gasket on preferred quartz socket tube top, even if a small amount of water seeps water into through quartz socket tube and mount pad gap, quartz socket tube gasket also can guarantee that water can not enter in quartz socket tube.Ultraviolet lamp tube two ends cover has socket type ceramic chamber lining, ceramic chamber lining one end is open one end center drilling, block ultraviolet lamp tube end with ceramic chamber lining, can avoid ultraviolet lamp tube to rock in quartz socket tube on the one hand, damage ultraviolet lamp tube or quartz socket tube, ceramic chamber lining can further seal ultraviolet lamp tube on the other hand.Described ceramic chamber lining external application gland seals, and described gland is fixed on fitting nut by bolt or screw; Tapping installing cables stuffing box in the middle of gland, the tie cable of ultraviolet lamp tube is passed by cable stuffing box through the perforate of ceramic chamber lining center drilling and gland, cable stuffing box sealing effectiveness is good, quartz socket tube impacted or other reasons beyond break in the situation that, water is still in air-tight state, and water can not flow out from tightness system.
As a kind of preferred version of ultraviolet lamp tube tightness system described in the utility model, there is ring-shaped pottery seal with buss pad on described ceramic chamber lining top, further improve on the one hand sealing property, can prevent ceramic chamber lining double swerve or damage with gland direct collision simultaneously.
As a kind of preferred version of ultraviolet lamp tube tightness system described in the utility model, flexible bolster between described cable stuffing box and ultraviolet lamp tube end, preferred resilient snubber is spring, prevents ultraviolet lamp tube double swerve in quartz socket tube.
As a kind of preferred version of ultraviolet lamp tube tightness system described in the utility model, fluted on described fitting nut and the joint face of gland, in groove, there is gland ring, preferred gland ring is the O type circle that tetrafluoroethylene is made.
As a kind of preferred version of ultraviolet lamp tube tightness system described in the utility model, one of the mount pad at same quartz socket tube two ends is that one of right-hand thread is left hand thread, can reduce the risk that quartz socket tube breaks and damages in the time that pretension is installed.
Beneficial effect:
Ultraviolet lamp tube sealing device structure described in the utility model is simple, install and change ultraviolet lamp tube tightness system easily, do not need whole ultraviolet sterilization device to take out and just can realize cleaning machine and more change jobs; Even if quartz socket tube breaks, water also can not flow out and destroy electrical system from tightness system, guarantees the safety of whole system; One of the mount pad at same quartz socket tube two ends is that one of right-hand thread is left hand thread, can reduce the risk that quartz socket tube breaks and damages in the time that pretension is installed.
