In a preferred embodiment of the present utility model, also comprise the valve pocket of giving vent to anger, described in give vent to anger that to be enclosed within the described valve cylinder end of with peripheral and be fixed on described installation ring body for valve pocket.
Owing to having adopted technological scheme as above, the utility model relies on the loading of spring when medium flows backwards, to close fast, thereby has reduced noise.Noise elimination check valve of the present utility model is simple in structure simultaneously, installs with practical very convenient, and can adapt to vertical installation and horizontal installation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of noise elimination check valve providing in figure, comprises valve body 100, valve cylinder 200, ring body 300, spool 400, spring 500, seal ring 600 and the valve pocket 700 of giving vent to anger is installed.
In valve body 100, there is a runner hole 110, the end of valve body 100 has a flange 120, the flange 120 of valve body 100 is provided with a centering ring 130 on valve cylinder 200 end faces, and this centering ring 130 inserts in the cylindrical shell 220 of valve cylinders 200 and the external diameter of centering ring 130 and the inner core face 221 of valve cylinder 200 match.
At the bottom of valve cylinder 200 has one 210, one end that valve cylinder 200 is relative with the cylinder end 210 is provided with an installing ring limit 230, and cylindrical shell 220 upper ends of valve cylinder 200 offer some exhaust ports 222.
Ring body 300 is installed and by bolt 310, is arranged on the flange 120 of valve body 100, and the installing ring limit 230 on valve cylinder 200 is pressed on the flange 120 of valve body 100, valve cylinder 200 is connected with valve body 100.
Seal ring 600 arranges to be installed between ring body 300 and the flange 120 of valve body 100, and seal ring 600 is arranged on the periphery on the installing ring limit 230 of valve cylinder 200.
The valve pocket 700 of giving vent to anger is enclosed within valve cylinder 200 peripheries and is fixed on and installs on ring body 300.
Spool 400 and spring 500 are arranged in valve cylinder 200, and its medi-spring 500 is arranged on the cylinder of spool 400 and valve cylinder 200 at the end 210, and the outer circumferential face of spool 400 coordinates with inner core face 221 slipper seals of valve cylinder 200; When spool 400 is closed the exhaust port on valve cylinder 200 222 completely, spool 400 withstands on towards one end end face of valve body 100 on the end face of centering ring 130 of valve body 100.
Working principle of the present utility model: when medium enters the runner hole 110 of valve body 100 with certain speed, first contact with spool 400, when the pressure of medium is greater than the elastic force of spring 500, spool 130 is pushed by medium, Compress Spring 500 moves axially, exhaust port 222 is opened, the medium valve pocket 700 of giving vent to anger by flowing through from exhaust port 222.When the pressure of medium is less than the elastic force of spring 500, spring 500 is because self elastic force is former thereby reset, and spool is promoted and moves axially by spring, exhaust port 222 sealings, and now the medium in the valve pocket 700 of giving vent to anger cannot reflux, and plays non-return effect.The utility model relies on the loading of spring 500 when medium flows backwards, to close fast, thereby has reduced noise, and noise elimination check valve of the present utility model is simple in structure simultaneously, installs with practical very convenient, and can adapt to vertical installation and horizontal installation.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
