Abstract

The utility model discloses a water seal multiplication automatic protection type horizontal row floor drain, including a shell(1) whose upper head face has a floor rain inlet(2) of an external expanding and bearing port. The inner side of the inlet(2) is overlapped with a cover(6) and a hopper(5). The peripheral wall of the shell(1) is communicated with a drainage outtake pipe(3), and a place inside the shell(1) and close to the outtake pipe(3) is provided with a water storage wall(4),and the height of the connection of the water storage wall(4) with the bottom and wall of the shell(1) is lower than the hopper by an appropriate distance. The place close to the shell(1) is provided with a pressure automatic eliminating valve(8) which is communicated with the atmosphere and the outtake pipe(3) and arranged on a guiding pipe(7). The utility model has the advantages that the water seal can conduct automatic protection, the loss of the evaporation is small, and the flat as well as thin volume is applicable to the drainage system during the construction of the thin plate buildings.

Description

Water seal multiplication automatic protection horizontally-arranged floor drain

This is suitable for novel a kind of water seal automatic protection horizontally-arranged floor drain that is applicable in the drainage system that relates to, and it is flat thin to relate to a kind of volume particularly, water seal degree of safety height, and the disengagement area that leaks outside is little, eliminates the environment-friendly household type floor drain of negative pressure harm.

So far, the traditional drain structure that is used for drainage system is outmoded, and water seal was lost efficacy serious, brought problems to surrounding enviroment, for numerous families bring many inconvenience.It is to water seal depth, and Chinese regulation and stipulation must not be less than 50mm, and Britain is defined as 70mm, and to avoid the managing harm of interior air-flow to water seal, therefore traditional floor drain size is bigger, and the volume heaviness is not suitable for the thin layer floor and uses.

This be suitable for novel purpose be to provide a kind of attenuate type, water seal is safe and reliable, can avoid managing interior air-flow, pressure oscillation is to the water seal multiplication automatic protection horizontally-arranged floor drain of water seal harm.

This is suitable for novel a kind of water seal multiplication automatic protection horizontally-arranged floor drain that is applicable to drainage system; it is characterized in that the housing (1) at the bottom of described floor drain comprises a hollow belt; its upper surface is the inlet of surface water (2) that extends out bellmouth; stacked from the top down placement is combed and is covered (6) in inlet (2) bellmouth; funnel (5); on the periphery wall of housing (1), connect drainage outlet pipe (3); contiguous outlet (3) is located to be provided with and housing (1) bottom surface in housing (1); the height that shell wall connects is lower than the water weir wall (4) of funnel one suitable distance; on drainage outlet pipe (3), contiguous housing (1) is located to be provided with the conduit (7) and the negative pressure that are communicated with atmosphere and gutter (3) and is eliminated valve (8) automatically.

Described negative pressure is eliminated valve (8) automatically and is comprised, the valve body (12) that is connected with conduit (7), place can open in the valve body (12) that the back is communicated with atmosphere and pipe network or close after make the lightweight valve block (9) of the tough and hard wear resistant that pipe network and atmosphere separate, the graticule mesh (10) that is communicated with atmosphere, the passage (11) that atmosphere is communicated with conduit (7).

Described housing (1) is circular or square.

Valve body (12), conduit (7) that described negative pressure is eliminated valve (8) can be made into one with housing (1), or negative pressure are eliminated valve body (8) and conduit (7) is installed on the drainage outlet pipe (3).

Originally suitable novel below in conjunction with the accompanying drawing description, described accompanying drawing is that this is suitable for novel preferred version, and it does not limit the utility model.

Fig. 1 is the longitudinal plan of floor drain;

Fig. 2 is that negative pressure is eliminated valve (8) schematic diagram;

Referring to Fig. 1 and Fig. 2; Wherein, component title:

In Fig. 1,1 housing, 2 inlets of surface water, 3 discharge water outlets, 4 water weir walls, 5 funnels, 6 comb covers, 7 conduits, 8 negative pressure are eliminated valve automatically.

In Fig. 2,9 valve blocks, 10 graticule mesh, 11 atmosphere and conduit interface channel, 12 valve bodies.

The course of work is as follows: cover 6,

funnel

5,2 enter the water storage bowl of the formed water seal that is made of housing 1 and water weir wall 4 from entering the mouth when ground water flows through to comb, superfluous water overflow water weir wall 4 by gutter 3 discharges, flowed into the outer drainage pipeline networks (not shown) that is communicated with gutter 3; Funnel (5) lower nozzle is inserted the following certain depth of the water surface in the water storage bowl, and the water surface that flows into water exceeds the lower nozzle formation water seal of funnel (5), stops the dusty gas that pipe network imports into to leak outside, and pollutes surrounding environment.Cover in housing upper end and extend out on the bellmouth, the comb on funnel 5 covers 6 pairs of floor drains and shields.Prevent that also other article from falling into the obstruction floor drain, also protect the resident, especially infant's safety.

When malleation appearred in the pipe network draining, traditional thin water seal was penetrated easily.In this is suitable novel; water storage bowl top communicates with pipe network, and part water storage bowl water surface is long-pending to be compared; the big several times of funnel 5 pore surface areas; the water storage bowl portion water surface is subjected to pipe network malleation impetus; rapidly hydraulic pressure is gone in funnel 5 pores; the water surface in the pore rises to B (the Δ AB among Fig. 1) by A naturally, thereby this suitable novel utilization water level multiplication principle of proof has been strengthened the water seal positive pressure protection.When negative pressure appears in pipe network, tend to water seal water is found time (or claiming atmospheric pressure that water seal is promoted to drain) therefore add negative pressure by conduit 7 and eliminate valve (8), introduce atmosphere automatically, to eliminate the harm of negative pressure to water seal at wall 4 rear portions, floor drain water weir.

Negative pressure shown in Fig. 2 is eliminated the schematic diagram of valve, and when negative pressure appearred in pipe network, negative pressure was sent to passage 11; pressure reduction appears up and down in valve block 9, and atmosphere backs down valve block 9 at once and makes the air admission passage, and negative pressure disappears immediately; so the floor drain water seal is protected, it is tranquil that the water surface keeps.

This is suitable for novel Water seal multiplication automatic protection type horizontal row floor drain and traditional ground Leak relatively, its advantage is that it is little that loss can be protected, be evaporated to water seal automatically, volume Drainage system in the flat thin building that is suitable for thin floor uses.
