Abstract
The utility model discloses a dual-purpose check valve, which comprises a check-valve body, wherein a plurality of sealing rings are arranged at positions at which pipe fittings at the front end and the rear end of the check-valve body are connected with an outer cylindrical surface; the inner parts of the pipe fittings at the front end and the rear end of the check-valve body are respectively provided with an inner thread; and each sealing ring is made of a polytetrafluoroethylene material. The dual-purpose check valve has the beneficial effect that: not only can metal pipelines be installed, but also hose pipelines can be installed.
Description
Technical field
The utility model relates to a kind of dual-purpose safety check, particularly a kind of dual-purpose safety check.
Background technique
The safety check on the existing market and the installation method of pipe way have only a kind of usually, and for clamp band type is installed, clamp band type only is suitable for and soft pipeline, because the excessive seepage that easily causes the joint of pressure; Also be unfavorable for simultaneously the connection of dissimilar pipelines.
Summary of the invention
At the shortcoming of existing safety check, the utility model provides a kind of novel dual-purpose safety check.
To achieve these goals, the measure taked of the utility model:
A kind of dual-purpose safety check comprises check valve body, and described check valve body rear and front end pipe fitting connects the external cylindrical surface place and is provided with some seal rings;
Pipe fitting inside, described check valve body rear and front end is provided with internal thread;
Described seal ring material is a teflon.
The beneficial effects of the utility model: the metal species pipeline can be installed, flexible pipe class pipeline can be installed again.
Description of drawings
Fig. 1, axle of the present utility model is surveyed schematic representation.
Embodiment
A kind of dual-purpose safety check as shown in Figure 1, comprises check valve body 2, and check valve body 2 rear and front end pipe fittings connect the external cylindrical surface place and are provided with some seal rings 1; Pipe fitting inside, check valve body 2 rear and front end is provided with internal thread 3.In the actual implementation process of patent, seal ring 1 material is a teflon, can prevent effectively that seal ring 1 is corroded in the course of the work; Connect the Embedded seal ring 1 that the external cylindrical surface place is provided with by check valve body 2 rear and front end pipe fittings, can improve the sealing that pipeline connects greatly; Simultaneously, pipe fitting inside, check valve body 2 rear and front end is provided with internal thread 3 and can makes safety check be suitable for the externally threaded pipeline of metal species band to connect.By the metal species pipeline can be installed, flexible pipe class pipeline can be installed again, reach the using scope that increases butterfly valve.Simultaneously, more than two kinds of installation methods, all can convenient and swiftly implement.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
