The upper part of the valve body 3 is provided with a plug cock 1 and a pipe joint 2; the plug cock 1 is arranged in the pipe joint 2 which is threaded connected with the valve body 3. The lower valve base 6 is arranged on the step of the lower inner wall of the valve body 3, an O-shaped sealing ring 5 is arranged between the lower valve base 6 and the valve body 3. The upper valve base 9 is arranged between the steps arranged in the plug cock1 and the upper part of the valve body 3. The utility model is of reasonable and simple structure, convenient for clean and arrangement, good heat insulation, good waterproof performance, automatic water drainage, good popularization value and market prospect.
Description
Technical field
The utility model relates to a kind of structure of automatic bailer of structure, particularly refrigerated container of freeing arrangement of freight container, cabinet of lade, belongs to the container technology field.
Background technology
Refrigerated container and general container all are one of important tool of modern goods transport, load and transportation in often meet to drench with rain to soak and hit with seawater, the waterproof of freight container, drainage measure, particularly refrigerated container must clean and often have condensate water after each cargo transport in fresh-keeping transportation.So the drainage performance of refrigerated container also is an important indicator weighing the refrigerated container performance.The version of existing refrigerated container freeing arrangement is varied, a kind ofly forms sluicing valve by drain plug, filtering net, draining folder valve etc.This freight container sluicing valve has drain function, but must manually open drain plug before the draining.When this sluicing valve has dirt, owing to filtering net can not be taken out, so this sluicing valve of cleaning is cumbersome.Another kind of sluicing valve has two sluicing valves that valve plug, valve seat constitute up and down by what shell, valve cap, dividing plate, ball float etc. constituted, though this sluicing valve draining automatically, but complex structure, thermal insulation is poor, gas barrier properties is poor, and freeing arrangement is easily lost under the vibration situation, and the two halves sealing effectiveness is bad up and down for sluicing valve.
The utility model content
The purpose of this utility model is a kind of simple in structure, good heat preservation performance, good waterproof performance will be provided, can discharge ponding in the case automatically, and can the inside and outside gaseous exchange of baffle box, and clears up the new construction automatic drain valve of refrigerated container easily.
The purpose of this utility model is achieved in that the new construction automatic drain valve, is provided with duct type valve body 3, is provided with upper valve base 9, lower valve base 6 in the valve body 3, and a float tank type valve plug 4 is arranged between upper valve base 9 and the lower valve base 6.The top of described valve body 3 is provided with cock 1, adaptor union 2, and cock 1 is arranged in the adaptor union 2, and adaptor union 2 is threaded with valve body 3.Lower valve base 6 is arranged on the step of valve body 3 lower inner wall, is provided with O-ring seals 5 between lower valve base 6 and the valve body 3.Upper valve base 9 is arranged between the step that is provided with in cock 1 and valve body 3 tops.Described upper valve base 9, lower valve base 6 is provided with the conical surface with the float tank type valve plug 4 two ends fully enclosed circular hole that is complementary for the PVC plate.The bucket wall periphery of described float tank type valve plug 4 is provided with pilot blade, when fluctuating with assurance valve plug 4, and all can be near the central axis position.
New construction automatic drain valve cock 1 is provided with interior Air Filter, and foreign material stop up sluicing valve in the anti-case, and valve body 3 is provided with outer Air Filter, can prevent that worm from entering in the case; The inside and outside plastics valve body 3 that adopts of case separates its good heat preservation performance; All waterproof connect and all adopt closely-pitched to connect, and are direction downstream on the structure, even screw thread has loosening phenomenon, and the water foaming layer of also can not bleeding; Valve plug 4 is under the deadweight effect, and its conical surface and lower valve base 6 driving fits have intercepted the convection current of the inside and outside gas of case, and when water can not float valve plug, when promptly forming water seal, its barriering effect is good especially.When buoyancy of water surpassed the valve plug deadweight, the valve plug come-up was discharged ponding, the big or other factors when case internal ratio case external pressure, valve plug then float and with upper valve base 9 driving fits, intercept gaseous exchange or outside water and pour in down a chimney.Seal ring 7 can seal and can move up and down and regulate according to concrete height in addition.The convenient cleaning of the utility model installed, and good heat preservation performance, choke drainage performance are good, and draining automatically has excellent popularization using value and market outlook.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
1 cock among the figure, 2 adaptor unions, 3 valve bodies, 4 valve plugs, 5 O RunddichtringOs, 6 lower valve bases, 7 seal rings, 8 side's plates, 9 upper valve bases.
The specific embodiment
Weld adaptor union 2 waterleakage part perforates with drain pan above the aluminium-alloy pipe joint 2.Lower valve base 6 adopts PVC pad middle part that circular hole is set, after periphery is provided with groove and O RunddichtringO 5 cooperates, on the step of valve body 3 lower inner wall of packing into.The keg float of float tank type valve plug 4 is enclosed between the upper valve base 9 and lower valve base 6 in the valve body 3, and two circle pilot blades are set on the outer wall of keg float.Upper valve base 9 adopts PVC pad middle part that the circular hole formation is set, and is arranged on the step that is provided with in valve body 3 tops.Cock 1 is provided with some filtering holes, and cock 1 is arranged in the adaptor union 2, and adaptor union 2 screws with valve body top.Seal ring 7 side's of packing into plates 8 are packed into as assembly on the valve body 3, are used for and the installing and fixing of freight container.In the freight container traffic process, after condensate water and rinse water flowed in the drain hose, when ponding buoyancy during greater than valve plug 4, valve plug 4 come-ups were discharged ponding.When buoyancy was decreased to valve plug 4 weight, valve plug 4 was closed the obstruct gaseous exchange again.When outside water level was higher than lower valve base 6, valve plug 4 come-ups until withstanding airtight upper valve base 9, can prevent that outer water from pouring in down a chimney.
