Abstract
The invention relates to a lower discharging manhole cover for a sealed steel lining plastic preservative solution, and the lower discharging manhole cover comprises an upper manhole cover plate, a lower manhole cover plate and a steel net, wherein the upper manhole cover plate is provided with an upper plate mounting hole; the lower manhole cover plate is provided with a lower plate mounting hole; the upper plate mounting hole and the lower plate mounting hole are cooperated; the upper manhole cover plate and the lower manhole cover plate are fixed into a whole by virtue of bolts; the lower manhole cover plate is installed above the upper manhole cover plate; the steel net is arranged between the upper manhole cover plate and the lower manhole cover plate; and the upper surface of the upper manhole cover plate is provided with a ground ring slot used for installing a sealing gasket. The lower discharging manhole cover for the sealed steel lining plastic preservative solution has a good sealing effect, and the sealing gasket is very easy and accurate to install.
Description
Technical field
The present invention relates to the storage tank technical field, especially relate to a kind of closed type steel lining and mould manhole cover under the impregnating fluid.
Background technology
Manhole cover product under the liquid that has had in the market is that carbon steel sheet single face lining is moulded lid, and this lid says that from use angle the manhole that is suitable for container top is made common corrosion cap.And often on reality is used, manhole is quite general under the liquid, and this just needs more safe and reliable lid carry on a shoulder pole this important task.Because, in daily production, the manhole flange body that steel lining is moulded (the manhole flange on the container); The plastic lining layer of its flange face; After the rotational moulding completion, meeting shrinkage distortion in the cooling process need be carried out the processing of road, back; And general job operation mainly is with electric planer for wood working processing, throws with the angle blinds at most again and polishes.But processing in any case, it is irregular that the lining that processes is moulded face (being sealing surface), is that planeness is poor on the one hand, two aspects are that the equation of equal altitude distance on plastic surface and steel flange plane is bigger.On such plane,, facts have proved it is to have the steady trouble of serious seepage if use common flat cover as the liquid lower sealing cover.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of good sealing effect, gasket seal that the closed type steel lining is installed easily accurately and mould manhole cover under the impregnating fluid.
According to technical scheme provided by the invention; Said closed type steel lining is moulded manhole cover under the impregnating fluid, comprises manhole cover upper plate, manhole cover lower plate and steel mesh, on the manhole cover upper plate, offers the upper plate mounting hole; On the manhole cover lower plate, offer the lower plate mounting hole; The upper plate mounting hole cooperates with the lower plate mounting hole, and manhole cover upper plate and manhole cover lower plate are through the bolt one, and the manhole cover lower plate is installed in the below of manhole cover upper plate; Said steel mesh is arranged between manhole cover upper plate and the manhole cover lower plate, offers the annular groove that sinks to the bottom that is used to install gasket seal at the upper surface of manhole cover upper plate.
The said width that sinks to the bottom annular groove is 45 ~ 55mm, and the degree of depth that sinks to the bottom annular groove is 10 ~ 15 mm.
The thickness of said manhole cover upper plate is 20 ~ 25 mm.
Good sealing effect of the present invention, very light and accurate when gasket seal is installed.

Fig. 2 is a left view of the present invention.
Fig. 3 is the front view of prior art manhole cover.
Fig. 4 is the left view of prior art manhole cover.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention mainly by manhole cover upper plate 1, upper plate mounting hole 1.1, sink to the bottom component set-ups such as annular groove 1.2, manhole cover lower plate 2, lower plate mounting hole 2.1 and steel mesh 3.
Sealing shaped steel lining is moulded manhole cover under the impregnating fluid; Comprise manhole cover upper plate 1, manhole cover lower plate 2 and steel mesh 3; On manhole cover upper plate 1, offer upper plate mounting hole 1.1, on manhole cover lower plate 2, offer lower plate mounting hole 2.1, upper plate mounting hole 1.1 cooperates with lower plate mounting hole 2.1; Manhole cover upper plate 1 passes through the bolt one with manhole cover lower plate 2; Manhole cover lower plate 2 is installed in the below of manhole cover upper plate 1, and said steel mesh 3 is arranged between manhole cover upper plate 1 and the manhole cover lower plate 2, the upper surface of manhole cover upper plate 1 offer be used to install gasket seal sink to the bottom annular groove 1.2.
The said width that sinks to the bottom annular groove 1.2 is 45 ~ 55mm, and the degree of depth that sinks to the bottom annular groove 1.2 is 10 ~ 15 mm.The thickness of said manhole cover upper plate 1 is 20 ~ 25 mm.
Closed type steel lining of the present invention is moulded manhole cover under the impregnating fluid; It is the special good lid of composite metal plastic corrosion-proof property; Principal feature is: be provided with at the liquid contact surface of manhole cover upper plate 1 sealing surface and gasket seal load bearing face place and sink to the bottom annular groove 1.2, can gasket seal 4 be set in and sink to the bottom annular groove 1.2, when compressing lid crush seal pad 4 through bolt; Gasket seal 4 can not produce gross distortion and skew, can play sealing function well.Simultaneously, the usual position of figure below is just in use installed gasket seal 4 wayward orientation and height generally speaking, and the present invention exactly can put into gasket seal earlier and sinks to the bottom annular groove 1.2, and is just very easily accurate during mounting cover again.
