In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a rubber lamella check valve with regulatory function, includes rubber lamella check valve body, set up in the adjusting device that the end inner wall of intaking of rubber lamella check valve body is used for adjusting the fluid velocity of flow, adjusting device including set up in the end of intaking of rubber lamella check valve body is used for blockking the fluid and reduce the fluid velocity of flow's stop part, connect in rubber lamella check valve body with several connection ropes of stop part.

The further improvement is that: the rubber flap check valve body and the blocking part are connected with the connecting rope through pull lugs.

The further improvement is that: the connecting rope is tied on the pulling lug.

The further improvement is that: the blocking part is provided with an auxiliary device for preventing the fluid from directly impacting the blocking part before the blocking part blocks the fluid to reduce the flow speed of the fluid.

The further improvement is that: the auxiliary device comprises an elastic body arranged on the blocking part and an anti-abrasion layer arranged on the outer surface of the elastic body.

The further improvement is that: the anti-abrasion layer is a butadiene acrylonitrile rubber anti-abrasion layer.

The further improvement is that: and the end face of the barrier part far away from the auxiliary device is provided with an adsorption layer for adsorbing impurities in the fluid.

The further improvement is that: the adsorption layer is an activated carbon layer or a carbon molecular sieve layer.

After the technical scheme is adopted, the utility model discloses beneficial effect does: the stop part is connected the rope setting through several and is held in the end of intaking of rubber lamella check valve body, and stop part stops the fluid and reduces the fluid velocity of flow, and the end of intaking at rubber lamella check valve body that rubber lamella check valve can be fine stops the fluid and reduces the fluid velocity of flow, possesses the function of adjusting the fluid velocity of flow, is difficult for causing the influence to rubber lamella check valve, is favorable to long-term the use.

Further effects are as follows: the connecting rope is tied on the pull lug, so that the connecting rope can be detached from the pull lug.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the description below are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive labor.
