As a further scheme of the utility model: and a protective cover is arranged on the outer wall of the top of the valve body.

As a still further scheme of the utility model: the valve body adopts a long cylinder structure.

Compared with the prior art, the utility model has the beneficial effects that:

the exhaust valve suitable for the sewage pipeline is reasonable in structure and novel in design, the valve body adopts a long cylinder structure, the position of the floating barrel is reduced, the distance between the inlet and the composite exhaust mechanism is increased, therefore, sewage can only be in the lower part of the valve body, the influence on the large exhaust assembly and the small exhaust assembly on the upper part can not be formed, the use performance of the exhaust valve under the sewage working condition is ensured, the practicability is high, and the reliability is high.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Example 1

Referring to fig. 1, in the embodiment of the utility model, the exhaust valve suitable for the sewage pipeline comprises a valve body 8, a float 7 capable of floating up and down is arranged inside the valve body 8, the float 7 is integrally connected with a connecting rod 6, a valve clack 4 is arranged on the top of the valve body 8 in a sliding mode, a composite exhaust mechanism is arranged on the corresponding position of the valve clack 4, and the composite exhaust mechanism comprises a small exhaust assembly and a large exhaust assembly.

In one aspect of this embodiment, the small exhaust assembly includes a small exhaust port 5 disposed inside the valve flap 4, and the connecting rod 6 is provided with a gasket cooperating with the small exhaust port 5.

In one aspect of this embodiment, the large exhaust assembly includes a large exhaust port 3 disposed at the top of the valve body 8 and engaged with the sealing surface of the valve flap 4, and a sealing seat 2 engaged with the outer wall of the valve flap 4 is installed on the inner wall of the large exhaust port 3.

In one aspect of this embodiment, the protective cover 1 is mounted on the top outer wall of the valve body 8.

Example 2

In another embodiment of the present invention, the embodiment is different from the above-mentioned embodiment in that the valve body 8 has an elongated cylindrical structure.

The working principle of the utility model is as follows: when the pipeline is put into use for the first time, because a large amount of air exists in the pipeline, a large amount of air needs to be rapidly exhausted through the exhaust valve, at the moment, the large exhaust port 3 acts, along with the exhaustion of the air, the water enters the inner cavity of the valve body 8, the buoy 7 floats upwards under the action of buoyancy to drive the connecting rod 6 to move upwards synchronously, and meanwhile, the valve clack 4 also closes the large exhaust port 3, and the small amount of air generated in the pipeline at the moment, it is discharged through the small exhaust port 5.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
