Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
As depicted in figs. 1 and 2, a kind of forged steel discharge opeing atmospheric valve, including the valve body 1 being made up of forged steel, in valve body 1, it is provided with the runner circulated for liquid, runner is provided with the valve module controlling runner break-make.Valve body 1 one end is provided with the flange 2 being connected with other pipelines, and the other end is provided with liquid outlet, and liquid outlet is provided with the plug 4 for closing liquid outlet.Owing to existing plug 4 is typically all directly exposed in external environment, when raining, the screw thread between plug 4 and liquid outlet can be intake, and causes occurring between the two corrosion.When atmospheric valve needs to open liquid outlet when emptying the liquid in pipeline, the liquid in pipeline is made to flow out from liquid outlet.If there is corrosion between plug 4 and liquid outlet, plug 4 of on the one hand back-outing more bothers, and on the other hand liquid can be mixed into rust when flowing out.So arranging sleeve 3 at liquid outlet outer surface, making sleeve 3 be set in outside plug 4, to prevent rainwater from falling directly on plug 4 and liquid outlet, causing the water inlet of the screw thread between plug 4 and liquid outlet that corrosion occurs.It is threaded connection between sleeve 3 and valve body 1, it is provided with external screw thread at the sheathed sleeve of valve body 1 outer surface 3, it is provided with female thread in the middle part of sleeve 3 inner surface, female thread and external screw thread cooperate, for branch sleeve 3 and valve body 1, improve the water-inlet-proof performance between sleeve 3 and valve body 1, it is to avoid rainwater enters into sleeve 3 bottom and is closed in sleeve 3 simultaneously.If having water bottom sleeve 3, steam when being heated, can be produced, still can make to produce between plug 4 and outlet a small amount of corrosion.Female thread on sleeve 3 is arranged in the middle part of sleeve 3 inner surface be in order to avoid fall sleeve 3 opening part end face rainwater along between external screw thread and female thread occur siphonage.If screw thread to be set directly at the end of sleeve 3 opening part, then fall and can enter sleeve 3 inwall in the gap between the external screw thread on valve body 1 and the female thread on sleeve 3 at this rainwater gone out, be unfavorable for preventing sleeve 3 from intaking.
