Abstract

The invention discloses an airtight deodorant blind well lid, which comprises a well lid, wherein antiskid strips are arranged on the upper surface of the well lid; the well lid is provided with a plurality of through holes, is arranged on a base, and is connected with the base through shackles; switching valves are arranged on the shackles; a deodorant material layer is arranged in the well lid; raised strips are arranged on the lower surface of the well lid. The airtight deodorant blind well lid has the advantages that the airtight deodorant blind well lid is novel in structure, high in safety coefficient, low in production cost, convenient to mount, difficult to damage and durable, and odor in a well can be prevented from being leaked.

Description

technical field [0001] The invention relates to an airtight anti-odor dark well cover. Background technique [0002] The main technical parameters of the well cover are: technical parameters test load: heavy 400KN, common type 250KN, light 125KN, bending strength: average 22MPa impact strength: average 10J / m2, compressive strength: average 25MPa, tensile strength: average 10MPa, elastic modulus: average 1000MPa, water absorption: 1%, acid resistance: the sample is soaked in 20% sulfuric acid solution for 48h, no corrosion on the surface, and 1% mass loss. It mainly has the following technical characteristics 1. High strength: Magnesite inspection has high compressive, bending, impact-resistant strength and toughness. After long-term use, the product will not appear crushed and damaged manhole covers, and can completely prevent the occurrence of "urban black hole" accidents. 2. Beautiful appearance: the surface pattern design of magnesite inspection manhole cover is exquisi...
