Abstract
The utility model relates to building and municipal articles, in particular to a sewage manhole cover, comprising a frame and a sealing plate made of rigid foam sponges. The sealing plate is inserted in the frame. A sealing ring is arranged between the sealing plate and the frame. Due to the arrangement of the sealing ring between the sealing plate and the frame, the sealing effect of the sewage manhole cover of the utility model is effectively enhanced. In addition, compared with conventional cast-iron manhole covers, the sewage manhole cover comprises the frame and the sealing plate made of the rigid foam sponges, achieving a great decrease in product weight, providing convenience for product transportation and construction, significantly reducing the cost, leaving no profit to thieves and reducing the probability of being stolen.
Description
Technical field
The utility model relates to building and municipal articles for use, relates in particular to a kind of blowdown well lid.
Background technology
Blowdown well lid of the prior art, general poorly sealed reality causes foul smell to leak, and influences the ambient air quality; And existing blowdown well lid all cylinder iron making, and product weight is big, and cost is higher; Be unfavorable for carrying and construction, and because it is lucrative, stolen easily.
The utility model content
The utility model provides a kind of sponge fat, its good sealing effect, and product is light, and cost of production is low, helps carrying and installation.
The technical scheme of the utility model is:
Include framework and sealing plate that the sponge of hard bubbling is processed, sealing plate is embedded in the framework, is provided with sealing ring between sealing plate and the framework.
Preferably, described sealing plate is provided with through hole and is used to stop up the sealing-plug of through hole.
Preferably, described framework is circular or rectangle.
The blowdown well lid of the utility model is provided with seal washer between sealing plate and framework, improved the sealing effectiveness of blowdown well lid effectively; And framework and the sealing plate sponge of hard bubbling is processed, and with respect to the well lid that existing cast iron is made, product is great significantly to be reduced, and helps the carrying and the construction of product, and cost also significantly reduces, and makes stealer profitless, reduces stolen probability.
Description of drawings
Fig. 1 is the blowdown well lid shape and structure figure in one embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done a detailed elaboration.
