Description

Strainer {STRAINER}

The present invention relates to a strainer, and more particularly, to a strainer capable of cleaning a filter with a filter fixed.

The strainer is installed at the front of the pump or equipment and is used to remove impurities or debris contained in seawater, oil and the like.

Simplex type, duplex type, and Y-type are used as the strainer. In order to clean the filter, it is necessary to separate the filter from the strainer installed in the pipe.

However, since a large number of pipes are arranged in a narrow space in the space where the pipe is installed, it is difficult to secure a separate space for separating the strainer filter.

The first filter opening / closing part 120 may be formed with a hole so that the fluid in the pipe P flows.

The first filter opening / closing part 120 may be formed in a frame having a filter net coupled thereto.

When there is a hole or a filter net in the first filter opening / closing part 120, the flow of the fluid in the first filter opening / closing part 120 is blocked, so that the load of the fluid can be prevented from being concentrated in the filter 110 part.

The second filter opening / closing part 130 is connected to the first filter opening / closing part 120 to open / close the first filter opening / closing part 120.

The second filter opening / closing part 130 may be connected to the first filter opening / closing part 120 through the coupling frame 131.

The coupling frame 131 may be formed integrally with the second filter opening and closing part 130.

The second filter opening / closing part 130 may be provided with a handle 132.

The second filter opening and closing part 130 may be made of the same material as the pipe P. [

The first filter opening / closing part 120 and the second filter opening / closing part 130 constitute a device for opening and closing the discharge part 112, thereby preventing the load of the fluid from concentrating on a part of the filter 110, . &Lt; / RTI >

The guide part 140 is installed on the pipe P and guides the movement of the second filter opening / closing part 130.

The guide part 140 may be installed on the pipe P having one side cut off.

4 and 5, the guide part 140 may include an inner gasket 141 and an outer gasket 142. [

The inner gasket 141 and the outer gasket 142 may have openings 143 formed at one side thereof so that the second filter opening and closing part 130 can be opened.

The inner gasket 141 and the outer gasket 142 may be formed with an end 144 so that the second filter opening / closing part 130 can be received.

The inner gasket 141 and the outer gasket 142 may be integrally formed.

The inner gasket 141 and the outer gasket 142 may be provided with reinforcement frames on the sphere back surface to withstand the load of the fluid.

A reinforcing frame may be installed on the end portions of the inner gasket 141 and the outer gasket 142 so as to be coupled to the pipe P through a bolting or welding connection.

The cut pipe P provided with the filter 110, the first filter opening and closing part 120, the second filter opening and closing part 130, the guide part 140 and the guide part 140 may be provided as one module .

Hereinafter, an embodiment of a strainer according to an embodiment of the present invention will be described.

6, a strainer according to an embodiment of the present invention may have a flange 114 formed on a filter 110 and installed on a pipe P.
