The utility model has the advantages of simple structure, convenient use, good use effect and the like.

Description

Multiple connection structure of check valve

Technical Field

The utility model relates to a sewage treatment accessory technical field specifically is a multiple connection structure of check valve.

Background

The check valve is a valve with a round valve clack and acts by self weight and medium pressure to block the medium from flowing backwards; it belongs to the automatic valve category, also called check valve, reflux valve or isolation valve.

The existing check valve adopts a hoop or thread mode for connection and installation, and the check valve only adopts one connection mode in actual use, so that the application range of the product is small, the product needs to be correspondingly used, and the production cost is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multiple connection structure of check valve to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a multiple connection structure of check valve, includes the check valve body, the both ends of check valve body be provided with coupling pipe respectively, coupling pipe's port be provided with the quick-connect chuck, and it has the internal thread to open on coupling pipe's the inside.

Furthermore, the connecting mode of the check valve body is also suitable for connecting other pipe fittings.

Compared with the prior art, the beneficial effects of the utility model are that: the multi-connecting structure of the check valve is different from the single connecting mode of the check valve of the prior product, and can be connected to the pipeline by adopting two connecting modes, the check valve of the structure has wider application range, can meet the use requirements of different connecting pipelines, and has universality and saves the production cost; and the connecting structure can also be applied to the connection of other pipe fittings.

The utility model has the advantages of simple structure, convenient use, good use effect and the like.
