Abstract
The utility model provides a check valve belonging to the technical field of valves and solves the problems that the welding part of a filtration pore of a filter screen of the traditional check valve is infirm, easy to rust and short in service life. The check valve comprises a valve body provided with a water inlet channel and a water outlet channel; a valve element is arranged in the valve body; a filter screen is arranged at the outer port of the water inlet channel on the valve body, one end of the filter screen is fixed on the valve body by glue and the other end is fixedly connected with a bottom cover for sealing the end surface. The filter screen is fixed in an annular groove at the outer port of the water inlet channel on a valve cap by the glue, thereby the check valve has the advantages of large filter screen area, firm fixation, no easy falling off and long service life.
Description
Technical field
The utility model belongs to valve technology field, particularly relates to a kind of safety check.
Background technique
The purposes of water pump is very extensive, and as draining on the agricultural, irrigation, water pump all can not extract the water that contains big impurity mostly, so in the port of intake pipe safety check and filter screen are installed.At present, safety check and filter screen installation are all needed instrument together, be not suitable for open-air the use especially.So someone has designed the safety check that has filter screen, for example, Chinese patent literature once disclosed a kind of Vertical lift check valve [China Patent No.: ZL99243134.4; Notice of authorization CN2388441Y], entrance point and the outlet end formed by the valve gap and the valve body of connection sealed to each other, the chamber is provided with the flap of unidirectional keying valve body sealing surface within it, wealthy lobe is inlaid on the valve petal shelf, valve petal shelf two ends expansion bearing is in valve gap, valve body coaxial aperture, be sleeved between check ring on the valve petal shelf and the valve petal shelf and be provided with spring, shoulder is provided with the filter screen by the collar location in the entrance point valve body.As can be known, though be provided with filter screen on the shoulder in check valve inlet end valve body, the useful area of this filter screen and entrance point area equate that filter opening area summation will be less than the entrance point area, so will influence flow of inlet water greatly from above-mentioned structure.
So the someone has designed filter screen is fixed on the outer structure of entrance point by the mode of welding again, because the filter opening in the filter screen is comparatively tiny, welding gun can't stretch in the net and weld, so can only carry out electric welding offline.Though this structure has solved the problem of above-mentioned existence, it is insecure still to exist soldering point, and soldering point just split after product used back a period of time, and filter screen comes off, and makes the problem of this product failure.Filter screen in this product can only adopt iron material to make, and iron very easily is corroded and gets rusty, so exist low problem in working life.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of filter screen and has adopted glue to be fixed on safety check on the valve body.
The purpose of this utility model can realize by following technical proposal: a kind of safety check, comprise valve body with exhalant canal and exhalant canal, in valve body, be provided with spool, it is characterized in that, intake tunnel external port place on the described valve body is provided with filter screen, one end of described filter screen is fixed on the valve body by glue, and the other end is fixed with the bottom that is used for this end face of shutoff.
In above-mentioned safety check, the intake tunnel external port place of described valve body has annular groove, and filter screen is fixed on the annular groove.One end of filter screen is inserted in the groove, splash into glue then in annular groove, the back filter screen just is fixed on the annular groove to treat that the glue solidifies, because glue has flowability, so glue connect have fixing comprehensively evenly, the soundness height makes the filter screen difficult drop-off.
In above-mentioned safety check, described filter screen and valve body all adopt copper product to make.Above-mentioned glue is used to connect the extraordinary glue of copper product and copper product, and this glue can be bought on market and obtain.
In above-mentioned safety check, the filter opening on the described filter screen is rounded.Adopt circular filter opening and adopt copper product to make, make it more not yielding, make filter screen more durable simultaneously in order to improve the hardness of filter screen.
In above-mentioned safety check, described filter screen in a tubular form, its core be parallel to intake tunnel the axle core.
In above-mentioned safety check, described bottom is connected on the filter screen by welding.
Compared with prior art, this safety check adopts glue that filter screen is fixed in the annular groove at the intake tunnel external port place on the valve gap, so that this safety check has screen area is big, and the advantage of fixation, difficult drop-off, long service life.
