Abstract

The utility model relates to a strainer valve which is characterized in that a strainer is arranged in passage of the valve which is communicated as a whole, namely, one end of the inlet end and output end of the casing of the strainer is communicated with the casing of the strainer. The other end of the casing of the strainer is the connecting end which is communicated with the pipe. So, the casing of the valve and the casing of the strainer are integrated. The passage at one end of the valve is connected with the pipe through the connecting end of the strainer, a detachable connecting structure is avoided between the valve and the strainer, simplifying the structure, reducing the detectable leakage rate, and reducing the connecting installation procedures of the valve and the strainer and the pipe.

Description

Filter valve

Strainer valve is a kind of valve that has filter, and the inlet of valve or row's mouth are being communicated with filter, through the also process filter filtration of fluid of valve.

Existing valve is not with filter, valve and filter each naturally independently, valve is by syndeton between them or connector with being communicated with of filter, as flange or be threaded.If fluid line is equipped with filter, pipeline also will be installed by-pass valve control simultaneously, is generally all connecting by-pass valve control and filter by syndeton.But syndeton has increased installation tie point and runner leak source and maintenace point.When filter keeps in repair and cleans in addition, all want first valve-off, open the connection at filter two ends again, maintenance has been cleaned also and will have been reconnected two ends.

The purpose of this utility model provides a kind of simple in structure, strainer valve of being convenient to install and use.

Strainer valve of the present utility model has valve, it is characterized in that: the passage of valve has the filter that is communicated as one.Just the end in the in-out end of filter housings and the housing of valve are communicated as one, and the other end of filter housings is the link that is communicated with pipeline.Like this, the housing of valve and the housing of filter are one, the passage of valve one end, link by filter is connected with pipeline, avoided separable syndeton between valve and the filter, simplify the structure, but reduced leakage point, reduced the process that is connected and installed of valve and filter and they and pipeline.Strainer valve and the link of pipeline still can adopt by the screw thread of normal employing, flange, clamp etc. and be connected.Valve can be multiple valve, as gate valve, ball valve, dish valve, stop valve etc.Same filter also can be multiple filter, for the filter of filter for the band filter core, in order to increase filter area, the filter inlet of filter core one end and the outlet of valve are connected as a single entity, the filter housings of the filter core other end has end cap, the filter core side is the outlet of filter, and filter outlet is the link with pipeline.Open the end cap that the filter housings of the filter core other end has, can conveniently take out filter core and clean or change.Between the edge of filter inlet and the valve passage inboard division board is arranged, the filter housings that the filter core other end has end cap stretches out from the side of valve passage, and filter inlet and outlet are communicated with the valve passage of division board both sides respectively.

Of the present utility model thus with by technology compare, housing with valve and filter is connected as a single entity, avoid valve body and filtered being linked and packed between the housing, reduced the easy leakage point of syndeton between the two, use accident and maintenance have been reduced, also make things convenient for being connected of strainer valve and pipeline, also made things convenient for the filter particularly replacing or the cleaning of filter core.

Accompanying drawing has been represented a kind of structural representation of heating strainer valve, further specifies the utility model below in conjunction with the example of accompanying drawing.

It is threaded connector (also can be the flange connector) that this heating strainer valve has an end entrance passage of two pass ball valves, 1, two pass ball valve housing 2, and housing other end exit passageway is the filter that is communicated as one.Filter housings inlet is communicated with the exit passageway of two pass ball valves and is integral, and it is the link that is communicated with pipeline that the other end of filter housings exports.Link also is threaded connector (also can be flange connector 6).Filter is the filter of band filter core 3, and the filter inlet of natural filter core one end and the outlet of valve are connected as a single entity, and between the edge of filter inlet and the valve passage inboard division board are arranged.The filter housings of the filter core other end is threaded end cap 5 (can certainly be flange end cap 15), and end cap is threaded with housing and accompanies sealing O shape circle.The filter housings that this other end of filter core has end cap stretches out from the side of valve passage, is more convenient for to the replacing maintenance and the cleaning of filter core.The housing of filter core side is the outlet of filter, and filter inlet and outlet are equivalent to be communicated with the valve passage of division board both sides respectively across division board.The filter outlet elongated end of valve passage in other words is the threaded ends (head) that is connected with pipeline.Like this, the threaded ends (or flanged ends) that needs only the strainer valve two ends just is connected and can will installs with the threaded connector (or flange connector) of pipeline.Open from the end cap that extends laterally, just can take out filter core and change or clean or maintenance.

Claims

1, a kind of strainer valve has valve, it is characterized in that: the passage of valve has the filter that is communicated as one.

2, as the said strainer valve of claim 1, it is characterized in that: the end in the in-out end of filter housings and the shell channel of valve are communicated as one, and the other end of filter housings is the link that is communicated with pipeline.

3, as claim 1 or 2 said strainer valves, it is characterized in that: filter is the filter of band filter core, the filter inlet of filter core one end and the outlet of valve are connected as a single entity, the filter housings of the filter core other end has end cap, the filter core side is the outlet of filter, and filter outlet is the link with pipeline.

4, as the said strainer valve of claim 3, it is characterized in that: between the edge of filter inlet and the valve passage inboard division board is arranged, the filter housings that the filter core other end has end cap stretches out from the side of valve passage, filter inlet and outlet respectively with the channel connection of division board both sides.
