Abstract

The utility model relates to an anti back smell and anti backflow device for the vertical type drain pipe, which is made by material with relatively good strength. The utility model comprises an outer crust, a fender board, a shaft, a cement weight case. A shaft is fixedly arranged on the one fourth of the fender board diameter and on the bottom of the outer crust as well. The fender board near the shaft is arranged on the internal crust, and a cement weight case is positioned below with a card board under. The fender board edge further from the shaft is arranged outside the external crust. As the cement weight case can keep the fender board in balance and seals the sewer pipe, the back smell and the back sewage is prevented. Meanwhile, the fender board rotates under the gravity by the seeper, and the water flows into the sewer pipe via the outlet port. When the flow ceases, the baffle returns to balance and maintain the former airproof.

Description

The anti-flavor anti-backflow device that returns of vertical drainage pipe

Technical field

The utility model relates to a kind of vertical drainage pipe to be prevented returning the flavor anti-backflow device, belongs to the water feeding and draining device of building field.

Background technology

It is existing that anti-to return the flavor floor drain varied, but because of its complex structure, cost height, be difficult for installing, and the anti-flavor anti counter-flowing poor effect of returning is not widely used in people's production and life always.

Summary of the invention

In order to address the above problem, the utility model provides a kind of improved vertical drainage pipe the anti-flavor anti-backflow device that returns, its material is intensity plastics preferably, and this apparatus structure is simple, cost is low, be easy to installation, and can prevent down effectively that water returns flavor and sewage flows backwards.

The anti-flavor anti-backflow device that returns of a kind of vertical drainage pipe described in the utility model is made up of crust of the device, baffle plate, axle and cement counterweight box, it is characterized in that: baffle plate diameter 1/4 place is fixed with axle, axle is fixed in the crust of the device bottom, the baffle edge of axle near-end is positioned at the crust of the device inboard, a cement counterweight box thereunder is set, cement counterweight box bottom is provided with clamp, and the baffle edge of axle far-end is positioned at the crust of the device outside.

Owing to be provided with cement counterweight box, make the baffle plate balance with the sealed sewer pipe road, so can prevent down effectively that water returns flavor and sewage flows backwards; Simultaneously, the gravity of ponding can make baffle plate rotate again, and water flows into sewer pipe through outfall, and current stop, and then baffle plate restores balance, and keeps original sealing state.

Description of drawings

Fig. 1 is a sectional side elevation of the present utility model.

Among the figure 1, crust of the device, 2, outfall, 3, baffle plate, 4, axle, 5, cement counterweight box, 6, clamp, 7, sewer pipe.

The specific embodiment

Referring to Fig. 1, the anti-flavor anti-backflow device that returns of a kind of vertical drainage pipe comprises crust of the device 1, baffle plate 3, axle 4 and cement counterweight box 5, be fixed with axle 4 on the baffle plate 3, the baffle edge of axle 4 near-ends is positioned at crust of the device 1 inboard, a cement counterweight box 5 thereunder is set, on the cement counterweight box 5 clamp 6 is set, the baffle edge of axle 4 far-ends is positioned at crust of the device 1 outside, thereby can cover crust of the device 1 bottom.

Cement counterweight box 5 can make baffle plate 3 balances with sealed sewer pipe road 7, prevents down that effectively water returns flavor and sewage flows backwards; Simultaneously, the gravity of ponding can make baffle plate 3 rotate again, and water flows into sewer pipe 7 through outfall 2, and current stop, and then baffle plate 3 restores balance, and keeps original sealing state.

Claims
