Abstract
The utility model relates to a manhole cover. The problems that welding is needed when an existing manhole cover and a hand-hole short section are connected, and thereby the manufacture difficulty and the production cost are increased are solved. The manhole cover comprises the manhole cover (1), the hand-hole short section (2) and a hand-hole cover (3), wherein the hand-hole cover (3) is hinged with the hand-hole short section (2), and the manhole cover is characterized in that the man-hole cover (1) and the hand hole short section (2) are manufactured into a whole. The manhole cover has the advantages that the manufacture is convenient, and the cost is low.
Description
Technical field
The utility model relates to a kind of manhole cover of wet tank, particularly a kind of manhole cover that has the hand hole pipe nipple.
Background technology
The top of wet tank generally all is provided with manhole and is connected with the manhole pipe nipple, work such as the workman enters in the jar by manhole and cleans, maintenance, and manhole plays the leak free effect by the manhole cover that covers on the manhole pipe nipple.Somebody's port lid is provided with hand hole and is connected with the hand hole pipe nipple, and the workman can carry out work such as liquid feeding by hand hole, and hand hole plays the leak free effect by the handhole cover that covers on the hand hole pipe nipple.
At present, the manhole cover that has a hand hole pipe nipple generally all is that hand hole pipe nipple and manhole cover is welded together.The junction of manhole cover and hand hole pipe nipple is owing to be circular configuration, so weld bond is more during welding; And the high temperature that welding is produced can make the weldment distortion, needs to proofread repeatedly in the process of welding, and this has just improved the requirement of welding process, has increased productive costs and cost of labor simultaneously.
The utility model content
In order to overcome the deficiency that exists in the background technology, the utility model provides a kind of manhole cover.This manhole cover has the advantage that its production technology is simple, productive costs is low.
The technical solution of the utility model is: this manhole cover comprises manhole cover 1, hand hole pipe nipple 2 and handhole cover 3, and described handhole cover 3 and hand hole pipe nipple 2 hinges is characterized in that: manhole cover 1 and hand hole pipe nipple 2 are for being made into integration.
The utlity model has following beneficial effect: the manhole cover 1 of this manhole cover and hand hole pipe nipple 2 are for being made into integration, a drawing of available steel plate, save the link that manhole cover 1 and hand hole pipe nipple 2 are welded, simplified production technology, reduced production cost.
Description of drawings
Fig. 1 is an integral structure cutaway view of the present utility model.
1-manhole cover, 2-hand hole pipe nipple, 3-handhole cover, 4-manhole pipe nipple, 5-storage tank, 6,7-seal ring.
The specific embodiment
The utility model is described in further detail below in conjunction with Fig. 1:
Manhole cover 1 is captiveed joint with the manhole pipe nipple 4 of storage tank 5 upper ends, and the junction between manhole cover 1 and the manhole pipe nipple 4 is provided with seal ring 6; Handhole cover 3 and hand hole pipe nipple 2 hinges, handhole cover 3 is provided with seal ring 7 with the junction of hand hole pipe nipple 4; Manhole cover 1 and hand hole pipe nipple 4 are for being made into integration, and the link that manhole cover 1 and hand hole pipe nipple 2 are welded has been saved in a drawing of available steel plate, has simplified production technology, has reduced production cost.
Claims (1)
1, a kind of manhole cover, it comprises manhole cover (1), hand hole pipe nipple (2) and handhole cover (3), described handhole cover (3) and hand hole pipe nipple (2) hinge is characterized in that: manhole cover (1) and hand hole pipe nipple (2) are for being made into integration.
