Floor Drain Gas Stopper

Abstract

Disclosed herein is a trap assembly for draining waste water toward sewer pipes while blocking back flow of odors. In a preferred embodiment the trap assembly comprises of a housing having a hollow interior, open, upper and lower ends. The housing is connected to a drain pipe at the lower end and extending outwardly therefrom into a substantially vertical orientation, a valve member formed of buoyant material; a retainer assembly connected to said housing in an at least partially supporting relation to a valve member. Further the valve member disposable into and out of sealing engagement with the valve seat dependent on direction of liquid flow along a flow path.

Claims

1. A trap assembly for draining waste water toward sewer pipes while blocking back flow of odors and preventing evaporation of drain water, said assembly comprising: a housing having a hollow interior, and open upper and lower ends, said housing connected to a drain pipe at said lower end and extending outwardly therefrom; a sealing engagement mounted on the upper end of the housing, said sealing engagement being a tubular hollow structure having an upper end and a lower end, and the upper end of the sealing engagement being a valve seat; a valve member, being a ball formed of buoyant material and having a size such that it closes the upper end of the sealing engagement when resting on the valve seat; wherein in presence of water in the housing, said valve member floats on the water leaving the upper end of the sealing engagement open for water flow and in absence of water in the housing said valve member closes the upper end of the sealing engagement, thereby preventing backflow of odors and water evaporation from the drain pipe.

2. The trap assembly of claim 1, wherein said valve member is made of plastic.

3. The trap assembly claim 1, wherein the assembly is covered by a floor drain cover.

DETAILED DESCRIPTIONS OF THE INVENTION

[0029] The following is a detailed description of example embodiments of the invention depicted in the accompanying drawings. The example embodiments are in such detail as to clearly communicate the invention. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention. The detailed descriptions below are designed to make such embodiments obvious to a person of ordinary skill in the art.

[0030] According to the trap assembly for draining waste water toward sewer pipes while blocking back flow of odors, keeps the floor drain trap from drying out preventing H2S gases into the houses or facility. One inventive feature of the present invention is the removable mounting or connection of the housing, as well as the remaining components of the flood valve assembly of the present invention, on the interior of the drain pipe. To accomplish such removable attachment, the present invention also comprises an attachment assembly, which is preferably adjustably disposed at least partially within the interior of the housing. The attachment assembly is preferably defined by at least one, but preferably, two cross members disposed in substantially transverse relation to one another, and further, which are specifically structured such that their length may be varied.

[0031] In one embodiment the invention is a trap assembly comprises of a housing 100 having a hollow interior, open, upper and lower ends. The housing 100 is connected to a drain pipe 101 at the lower end and extending outwardly therefrom into a substantially vertical orientation, a valve member formed of buoyant material; a retainer assembly connected to said housing in an at least partially supporting relation to a valve member.

[0032] FIG. 1 shows the parts of the present floor drain h2s gas stopper comprising the housing 100, a ball seal 106, a gas stop ball 105 and a floor drain cover 104.

[0033] Further the valve member disposable into and out of sealing engagement with the valve seat dependent on direction of liquid flow along a flow path. And the housing of the trap assembly for draining waste water toward sewer pipes while blocking back flow of odors further comprises of a head assembly removably secured within the upper end of the housing, the head assembly includes a hollow interior and open proximal and distal ends.

[0034] Also, according to the invention the valve member is movably contained within the housing and along the flow path. Further, the retainer assembly is disposed to normally retain said valve member out of said flow path. The trap assembly for draining waste water toward sewer pipes while blocking back flow of odors the valve seat is removably mounted on the head assembly. The valve seat and the upper end collectively define at least a portion of a flow path through the housing. The specific structural embodiment of each of the cross members may take the form of a hexagon shaped turnbuckle or “hex-turnbuckle” having a threaded bolt protruding from each opposite end thereof.

[0035] Further, the ball 105 rest on a seal 106 preventing gases to escape. The water in the trap will stay for months with a plastic ball in place giving a double seal. Water and the ball rest on the seal. It also allows water to drain freely down trap. The float or gas stopper to allow water to drain and stop gases from entering home or facility from a dry floor. The float or gas stopper rest on the seal to prevent floor drain water from evaporating and allowing H2S gases from entering your home or facility from dry floor.

[0036] The opposite extremities of each of the threaded bolts preferably have a sharpened or pointed configuration which extends through pre-formed openings or apertures in the body of the housing such that the sharpened ends of the cross members may penetrate, and thereby, removably engage the interior surface of the standing drain pipe.

[0037] Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiment shown. This application is intended to cover any adaptations or variations of the present invention. The dimension mentioned herein is an approximate value and in no way limits the scope of the invention.

[0038] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.
