Direct-draining type sewer floor drain with three cavities

Abstract

A direct-draining type sewer floor drain with three cavities is used for a ground sewer, consists of a connector, a grate cover, a body and a bottom cover, and is characterized in that outer connecting threads are formed at the upper end of the body; the inside of the body is divided into two function cavities comprising a water draining cavity and a water returning cavity and water draining function space; bottoms of the two function cavities are through channels; a water draining opening which is communicated with the water draining function space is formed in the upper end of a wall of the water returning cavity; the bottom cover is a copying concave bottom cover; the shape of the section of the bottom cover is the same with that of the section of the body; the outside of the connector is square, and the inside of the connector is round; a grate cover shelving table and a threaded connecting table connected with the body are arranged in the connector; the bottom cover is arranged on the bottom of the body in a blocking manner; the outer threads at the upper end of the body are in threaded connection with inner threads at the connecting end of the connector; and the grate cover covers an upper port of the connector. The direct-draining type sewer floor drain is in a channel water draining mode. Compared with the traditional floor drain, the direct-draining type sewer floor drain has the advantages that the wetted perimeter of the direct-draining type sewer floor drain is weaker than that of the traditional floor drain by 50%, and the water draining resistance is greatly reduced; because the sectional area of the water draining opening of the direct-draining type sewer floor drain can be greater than or equal to that of a water inlet, the manual water draining efficiency is high; and actually, when in full-diameter water draining, the direct-draining type sewer floor drain has a siphon negative-pressure water draining function.

Description

technical field [0001] The utility model relates to a three-chamber direct-drain type sewer drain used for ground sewerage. Background technique [0002] Floor drains are similar functional facilities such as kitchens and toilets, and are used in conjunction with ground drainage devices to meet the ground drainage needs of the above sites. [0003] The previous floor drain adopts the traditional design of water seal and gap drainage. Although it has the function of ground drainage, it can achieve the purpose of drainage to a certain extent. However, because of the traditional design of the floor drain, the wet area during drainage is more than twice that of the normal drainage channel, not only the drainage resistance is large, which affects the drainage effect, but also increases the chance of dirt and dirt, causing easy blockage; in addition , the floor drain of the traditional design, the drainage cross-sectional area of ​​the drainage gap is much smaller than the water ...
