Abstract

A sewer deodorizing automatic valve is particularly useful for the condition that water channels (including a toilet sewer) on and off the upstairs and downstairs of a high-rise building are communicated up and down and mutually influenced. The edge of a hinged stainless steel valve movable sheet (4) is tightly attached to a rubber block (2) with an inclination angle with a vertical plane, and when a sewer is waterless at ordinary times, the valve movable sheet (4) can freely rotate on a valve shaft (6), and can downwards hang to a vertical position under the action of gravity, but is blocked when meeting the inclined plane of the edge rubber block (2) and is tightly attached to the valve movable sheet. When water enters the sewer inlet pipe (1), water flow rushes the valve movable sheet (4) to flow to a sewer of a lower floor, and when water inlet stops, the valve movable sheet (4) automatically droops to cling to the inclined plane of the rubber block (2) under the action of gravity, so that odor of the sewer is prevented from overflowing to the sewer of the upper floor.

Description

Automatic odour-proof valve for sewer

Technical Field

The utility model relates to a device capable of preventing odor of a downstairs sewer from overflowing to upstairs rooms, belonging to the field of building sanitation.

Background

The existing high-rise building sewers (including toilet sewers) are communicated up and down, and the odor of the sewer of a downstairs user can float to the sewer of an upstairs user to enter a room (particularly a toilet kitchen room), so that the life of neighbors is seriously influenced and cannot be solved.

Disclosure of Invention

In order to solve the problem of mutual circulation of odor of sewer of upstairs and downstairs, the utility model provides a pipeline separation device capable of separating the odor of the sewer from the downstairs, and the pipeline separation device is provided with a valve movable sheet (4) which can be turned up and closed at any time along with the change of water flow, when a water inlet pipe (1) of the upstairs sewer enters water, water flow can flush the valve movable sheet (4) to ensure that waste water smoothly flows to a lower layer, and the valve movable sheet (4) can be automatically closed when the water flow stops, so that a passage for overflowing the odor of the downstairs sewer is separated, and the trouble that residents on the upstairs are influenced by the odor is solved.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a hinge-shaped valve (4), (5) and (6) are designed, a valve fixing piece (5) is horizontally fixed at the top of a rubber block (2) by a nail (9), a valve movable piece (4) can freely rotate on a valve shaft (6), the valve movable piece (4) can always keep a vertical position under the action of gravity in a natural state, an inclined plane of the rubber block (2) with an inclined plane is abutted against the valve movable piece (4) to enable the valve movable piece to be inosculated, the valve movable piece (4) can always cling to the inclined plane of the rubber block (2) under the action of gravity, and the device is placed into a sewer pipeline to block the flow of gas in the pipeline; when the upstairs sewer is filled with water, the water flow rushes the valve movable sheet (4) to be upwards turned up, so that the water flow smoothly flows to the lower layer water pipe, when the upstairs sewer stops filling the water, the valve movable sheet (4) automatically droops under the action of gravity and is matched with the inclined plane of the rubber block (2) again, the circulation of gas in the pipe is cut off again, and the interference of odor is avoided.

The utility model has the beneficial effects that: the odor of the downstairs sewer can be prevented from overflowing to the upstairs sewer, and the life quality of upstairs residents can not be influenced.

The utility model is further illustrated with reference to the following figures and examples:

Figure 1 is a general structure of the present invention,

figure 2 is a block cross-section of the valve,

figure 3 shows the valve and the rubber block,

figure 4 is a view of the movable flap of the valve,

figure 5 is a view of the valve retainer plate,

in the figure, 1, a sewer inlet pipe, 2, an inclined plane rubber block, 3, a cuboid shell, 4, a valve movable sheet, 5, a valve fixed sheet, 6, a valve shaft and an outer sleeve thereof, 7, a sewer outlet pipe, 8, a vertical plane rubber block and 9, nails are arranged.

Detailed Description

In the figure 1, the valve movable sheet (4) is tightly attached to the inclined plane of the rubber block (2) under the action of gravity and is matched with each other to cut off the air circulation between the water inlet pipe (1) and the water outlet pipe (7), once the water inlet pipe (1) enters water, water flow can flush the valve movable sheet (4) and can be turned upwards, and the water flow can smoothly flow to the water outlet pipe (7); once the water flow stops, the turned-up valve movable sheet (4) automatically droops under the action of gravity and is tightly attached to the inclined plane of the rubber block (2) to be matched with each other, so that the air circulation of the downstairs sewer is cut off again, and the odor is prevented from overflowing upwards.

In the embodiment shown in fig. 2, the upper end of the valve movable sheet (4) is fixed on the valve shaft (6) and can freely rotate on the shaft, when the water inlet pipe (1) does not enter, the valve movable sheet (4) sags under the action of gravity and is always attached to the inclined plane of the rubber block (2) and is matched with the inclined plane of the rubber block, the opening of the water inlet pipe (1) is sealed, the gas flow between the water inlet pipe and the water outlet pipe can be cut off, and the purpose of deodorization is achieved.

In the embodiment shown in fig. 3, the valve fixing piece (5) is fixed on the top of the rubber block (2) by a nail (9) to play a role of fixing, so that the valve moving piece (4) can rotate freely without falling off.

In the embodiment shown in fig. 4, the shape of the valve flap (4) in plan view is shown.

In the embodiment shown in fig. 5, a plan view of the valve retainer plate (5) and the position of the two nails (9) is shown.

Claims

1. The utility model provides a deodorant automatic valve of sewer, characterized by: the hinge-shaped valve movable sheet (4) is tightly attached to the inclined plane of the rubber block (2) with the inclined plane, the valve movable sheet (4) can freely rotate on the valve shaft (6), and under the action of gravity, the valve movable sheet (4) is hung on the valve shaft (6) and can naturally droop to be vertical to the ground, but is blocked by the inclined plane of the rubber block (2) with the inclined plane to tightly lean against the inclined plane of the rubber block (2) to form the seal of the sewer inlet pipe (1).
