Abstract
The utility model relates to a pipeline valve, and particularly relates to and discloses a Y-shaped filtering stop valve. The Y-shaped filtering stop valve comprises a valve body (1), a valve element (2) and a Y-shaped branch pipe (3). The Y-shaped filtering stop valve is characterized in that the Y-shaped branch pipe is directly arranged at the bottom of a valve body and tilts downwards, the Y-shaped branch pipe and an outlet of the valve form an included angle which is about 45 degrees, and the structure is compact. A filtering screen in the branch pipe is located in a passageway between an inlet of the valve and a valve seat, and can effectively filter and periodically clean impurities. Therefore, quality of fluid at the outlet is improved, and the leakage of the valve caused by untight closing due to the fact that solid particle impurities are accumulated on the valve seat is prevented. The Y-shaped filtering stop valve integrates functions of a stop valve and a filter, the filtering function is firstly achieved, the shortcoming that the stop valve is not suitable for pipelines for media with particles is overcome, and the application range of the medium of the stop valve is widened.
Description
Technical field
The utility model relates to a kind of pipeline valve, is specifically related to a kind of Y type and filters stop valve.
Background technique
Stop valve is widely used a kind of valve in the medium-small diameter pipeline, both can play closing function, again capable of regulating flow quantity.Structural feature is that medium is entered the high-order bit out from the low position of valve, and spool falls to be stuck on the valve seat and can cut off medium.When valve open, will be gathered on the valve seat if contain solid particle polluter in the fluid, so that cause leakage because of gapped between spool and the valve seat during valve closing.Particularly some Chemical Manufacture needs strict the cut-out, because poisonous and harmful, inflammable and explosive medium are in case leak and might cause poisoning, explode, catch fire or Accident due to quality.
Therefore, for solving the problems of the technologies described above, in conjunction with the structural feature of stop valve, be necessary at the valve inlet place filtrating equipment to be set, before flow is crossed valve seat, its solid particle polluter filtered down.
The model utility content
The purpose of this utility model is to provide a kind of self has the Y type of filtering solid particles impurity function to filter stop valve.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of Y type filters stop valve, comprise valve body (1), spool (2), Y type arm (3), it is characterized in that at valve inlet and valve base chamber channel setting filter screen filtering solid particles impurity, guarantee again to close and closely not leak behind the valve opening, and improved the outlet fluid mass.
Y type of the present utility model filters stop valve, and described valve body (1) two ends are provided with imports and exports internal thread spanner joint (4), and inside is provided with seal valve seat (5), and the upper end is connected with valve gap (6).Valve adopts with pipeline and is threaded.
Described spool (2) is discoid, places valve cavity, is connected with valve rod (7) and handwheel (8).Rotation hand wheel can be with the movable valve plug lifting, thereby adjusts the gap between spool and the valve seat, realizes valve opening and closing and adjust flux.
Described Y type arm (3) is arranged on valve body bottom, and is downward-sloping, with the valve export angle be about 45 °.The built-in filter screen of arm (9), filter screen are positioned at valve inlet and valve base chamber passage.The arm bottom is provided with end cover (10), opens that end cap is desirable to go out filter screen cleaning solid particle polluter.
Compared with prior art, the utlity model has following features and beneficial effect: described Y type arm directly is inclined at valve body bottom, compact structure.Filter screen is positioned at valve inlet and valve base chamber passage in the arm, can effectively filter and periodic cleaning impurity.Not only improved the outlet fluid mass, can prevent from also that solid particle polluter is gathered in to cause valve to fit badly and leak on the valve seat.This valve integrates stop valve and filter function, and filtration is front, has overcome stop valve and has not been suitable for shortcoming with the granule medium pipeline, has enlarged the media applications scope of stop valve.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
With reference to Figure of description 1, described spool (2) and valve rod (7) and handwheel (8) are connect, place valve seat (5) top.Rotate handwheel, by the lifting of valve rod band movable valve plug, thereby valve opening and closing and adjust flux are realized in the gap of adjustment spool and valve seat.Valve gap (6) works to support valve rod and sealing medium.
Filter screen (9) is packed in the Y type arm (3), and described filter screen is positioned at the valve inlet fluid passage just, can filter the solid particle polluter that flows to valve.Seal with screwed joint is adopted with end cap (10) in described arm bottom.Regularly opening end cap can clear up impurity or change filter screen.
Claims (4)
1. a Y type filters stop valve, comprises valve body (1), spool (2), and Y type arm (3) is characterized in that at valve inlet and valve base chamber channel setting filter screen filtering solid particles impurity, guarantees again to close and can closely not leak behind the valve opening.
2. Y type as claimed in claim 1 filters stop valve, it is characterized in that: described valve body (1) two ends are provided with imports and exports internal thread spanner joint (4), inside is provided with seal valve seat (5), and the upper end is connected with valve gap (6), and valve adopts with pipeline and is threaded.
3. Y type as claimed in claim 1 filters stop valve, it is characterized in that: described spool (2) is for discoid, place valve cavity, be connected with valve rod (7) and handwheel (8), rotation hand wheel can be with the movable valve plug lifting, thereby adjust the gap between spool and the valve seat, realize valve opening and closing and adjust flux.
4. Y type as claimed in claim 1 filters stop valve, it is characterized in that: described Y type arm (3) is arranged on the valve body bottom, downward-sloping, with the valve export angle be 45 °, the built-in filter screen of arm (9), filter screen is positioned at valve inlet and valve base chamber passage, and the arm bottom is provided with end cover (10), opens that end cap is desirable to go out filter screen cleaning solid particle polluter.
