Abstract

The utility model relates to the valve for sewage automatic check and bacteria inhibition, belonging to the technical field of fluid valve. The technical proposal is that the utility model includes a valve body, two valve bases, two flanges, a floating ball and a bolt joint piece; the hollow floating ball is disposed in the valve body, both valve bases are arranged in the holes on both ends of the valve body and have no relative rotation to the valve body, the end faces of both flanged are closely clung to the end faces on both ends of the valve body and fastened by the bolt joint piece. The utility model adopts the PVC plastic of the bacteria-inhibited material and flexible plastic of the bacteria-inhibited material. In addition, the utility model is characterized in that the utility model can effectively prevent sewage from overflowing into the room because of the sewer blocking in an automatic way, can effectively obstruct the stench, toxic gas, bacteria and small insects to cut off the possible transmission of epidemic through sewers, besides the utility model is anti-corrosion and fire resistant with a low production cost; the installation of the utility model is convenient and the utility model can be used matched with the original pipeline; in addition, the utility model boasts of a wide use.

Description

Sewage automatic braking, antibacterial valve

Technical field

The utility model relates to sewage automatic braking, antibiotic valve, belongs to the Fluid valve technical field.

Background technique

Sewerage in nearly all buildings such as family, hotel, office all adopts the structure of trap to come shutoff drain pipe interior smell and toxic gas at present, but this plugging structure, there is following defective: 1. when total drain pipe stops up, gathering along with sewage, wastewater level rises and crosses trap, constantly sewage dirt is overflowed, and causes whole indoor filth completely, stinking smell assaulting one's nostrils, and trap loses original function fully; 2. the effectively intrusion of shutoff small worm, germ, particularly more can't the shutoff toxic gas when the water in the trap is dry and the intrusion of germ, the incident that nearly 200 people in Amoy Garden, Hong Kong in 2003 infect SARS is exactly the best explanation that is caused by this reason.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of sewage automatic braking, antibacterial valve, and is achieved by following technical proposals.

1. it comprises valve body, valve seat, flange, hollow ball float and bolt connection piece, ball float places in the valve body, two valve seats place respectively not have in the hole at valve body two ends and with valve body and relatively rotate, and two end face of flange are close to the end face at valve body two ends respectively and by bolt connection piece it are fastenedly connected.

2. described valve body, valve seat, flange are made by the Modifying Character for PVC Plastic of adding antibacterial material, and described ball float is then made by the soft plastic that adds antibacterial material.

3. described valve seat is a cirque body, Hole chamfering in the one end.

The beneficial effects of the utility model are: 1. can prevent from effectively automatically to overflow to indoor phenomenon because of sewerage blocks the sewage dirt that causes, need not power supply and personnel management; 2. can effectively intercept the invasion of foul smell, poison gas, germ and small worm in the sewerage, thereby cut off the propagation path that to cause epidemic situation by sewerage; 3. it is low to have characteristics anticorrosive, anti-aging, that uvioresistant is indeformable, fire-retardant and cost of production; 4. easy for installation, and can with the supporting use of original pipeline; 5. of many uses, except that using, public places such as the commercial affairs of unit such as the food that is specially adapted to hygienic requirements, food and drink, medicine, hospital and crowd massing, hotel, teaching building, laboratory also can be used as some industrial department liquid level limiter.

Description of drawings

Accompanying drawing is the utility model structural representation

1 is connecting tube among the figure, the 2nd, and flange, the 3rd, valve seat, the 4th, valve body, the 5th, ball float, the 6th, bolt connection piece, the 7th, sewer, the 8th, trap, the 9th, total sewer.

Embodiment

Below in conjunction with accompanying drawing the utility model figure is described further.

Referring to accompanying drawing, valve body 4, valve seat 3, flange 2 are made by the Modifying Character for PVC Plastic of adding antibacterial material among the figure, and 5 soft plastics by the antibacterial material of interpolation of ball float are made.Valve body 4 is dolioform, and the aperture at two ends is slightly larger than the diameter of ball float 5 so that put into ball float 5, and valve seat 3 stationary fits or the Kong Zhongyu valve body 4 that excessively is matched with valve body 4 two ends circumferentially do not have and relatively rotate.Connecting tube 1 on the upper and lower flange 2 is connected with U type water trap 8 with sewer 7 respectively, and the end face of the end face of flange 2 and valve body 4 is close to, and coats silicon sealant in case the gap seepage is fastenedly connected it with six bolts again on junction plane.

During normal state, ball float 5 is on the valve seat 3 below of the effect whereabouts of gravity, and resiliently deformable slightly, the endoporus of valve seat 3 has arc round angle, surface of contact guarantees better seal thereby ball float and valve seat 3 have closely, the antibacterial material that is in addition adopted makes this structure of the present utility model be enough to shutoff sewerage interior foul smell, poison gas, germ and small worm.

Along sewerage down during row, 4 li of short time inner valve bodies are poly-to be had a certain amount of water, ball float 5 to lift off a seat under buoyancy function 3 to bubble through the water column as waste water, and waste water then enters total drainage pipeline 9 by valve seat 3 through trap 8.

When total drainage pipeline stopped up, the waste water water level rose, and advanced 8 by trap and entered valve body 4, and ball float 5 just is floated to top valve seat 3 until sealing this valve seat 3 fully along with sewage level rises, thereby in the complete shutoff sewage inlet chamber.

Claims

1. sewage automatic braking, antibacterial valve, it is characterized in that it comprises valve body, valve seat, flange, ball float and bolt connection piece, ball float places in the valve body, two valve seats place respectively not have in the hole at valve body two ends and with valve body and relatively rotate, and two end face of flange are close to the end face at valve body two ends respectively and by bolt connection piece it are fastenedly connected.

2. sewage automatic braking according to claim 1, antibacterial valve is characterized in that described valve body, valve seat, flange make by the Modifying Character for PVC Plastic of adding antibacterial material, and described ball float is then made by the soft plastic that adds antibacterial material.

3. sewage automatic braking according to claim 1, antibacterial valve is characterized in that described valve seat is a cirque body, Hole chamfering in the one end.
