Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is perspective view of the explosion of the invention.
Specific embodiment
As shown, check valve apparatus, including valve body 8, it is equipped with core assembly in the valve body 8, the outlet end of valve body 8 connects
It is connected with dismountable connector 7, in the present embodiment, connector 7 is threaded in the outlet end of valve body 8, by connecting 7 screw thread of connector
It connects on valve body 8, the connector 7 of different model can be replaced according to need, to connect various sizes of adapter tube, applicability is wide.In valve
The liquid feeding end of body 8 is equipped with the adjustable inlet of openings of sizes and is mainly accomplished by the following way in the present embodiment: in valve body 8
Liquid feeding end be communicated with match mobilizable feed liquor set 6, specifically, be valve body 8 liquid feeding end be equipped with external screw thread, into
Liquid set 6 is equipped with the internal screw thread to match with external screw thread, and feed liquor set 6 is threaded on valve body 8, in the peripheral wall of feed liquor set 6
It is equipped with through-hole, in the present embodiment, to guarantee uniformly accurately to control flow, is uniformly provided at four on the peripheral wall of feed liquor set 6
Through-hole in same level, the axial gap of the formation between the base end wall of valve body 8 and the through-hole are inlet, valve body
8 bottom end is equipped with opening.When adjusting the size of inlet, only feed liquor need to be covered 6 and be rotated up and down on valve body 8, that is, can control into
The opening and closing and size of liquid mouth.In addition to the present embodiment it is this mode of the through-hole to adjust inlet is set on feed liquor set other than,
There are also other modes, for example port is arranged in the peripheral wall of the liquid feeding end in valve body, and the size of port is controlled with the movement that feed liquor covers
Deng.
Feed liquor set 6 falls off after being threadedly coupled on valve body 8 in order to prevent, on the inner wall of feed liquor set 6 and in the inner screw thread
Top is equipped with the first card slot, is equipped with matched first circlip 10 in first card slot, the first circlip 10 can be prevented
Only internal screw thread screws out external screw thread, plays good position-limiting action.In the present embodiment, the lower section of internal screw thread is arranged in through-hole, when
Gap, that is, inlet size of the through-hole with feed liquor set 6 when mobile to 7 direction of connector on valve body 8, between through-hole and valve body 8
It will be gradually reduced, conversely, being then gradually increased, maximum is no more than the size of through-hole, in order to help feed liquor set 6 to be tightened on valve body 8
It is the not permeable leakage feed liquor set 6 of liquid, is additionally provided with gasket 1 in the inner bottom surface of feed liquor set 6, valve body 8, which can be screwed into, is adjacent to gasket 1
Position.
The valve body 8 has the spool chamber and filter chamber communicated, and spool chamber covers 6 close to feed liquor close to connector 7, filter chamber,
Valve body 8 is provided inwardly with annular flange between spool chamber and filter chamber, and the annular flange is equipped in the one side towards spool chamber
Seal washer 4, core assembly include spool, spring and fixed frame, and the spool being in contact with sealed loop-pad is placed in spool chamber
3, seal washer 4 and spool 3 cooperate in reversed feed liquor with good sealing effect, prevent liquid countercurrent, spool 3 has valve
Bar is arranged with spring 5 on valve rod, and valve rod provides guiding role to the movement of spring 5, is equipped with and spool 3 in the top of spring 5
The fixed frame 2 to match is additionally provided with the valve rod hole to match with the valve rod, the inner cavity of fixed frame 2 and connector 7 on fixed frame 2
Match.When liquid forward direction enters valve body 8, spool 3 will be mobile to 7 direction of connector under the pressure of liquid, and and convex annular
Gap is flowed out between edge, so that liquid can pass therethrough, and valve rod also moves through valve to fixed frame 2 with the movement of spool 3
Rod aperture avoids the movement for hindering spool 3.
Filter screen 11 is equipped in filter chamber, filter screen 11 can first be filtered liquid, then be liquid by connector 7 into
Enter corresponding pipeline, prevent the liquid with impurity from precipitating on pipeline or corresponding application apparatus, influences at that time using life.?
The inner wall of the valve body 8 of the liquid feeding side of filter screen 11 is equipped with the second card slot, and matched the is equipped in the second card slot
Two circlips 9, the second circlip 9 can block filter screen 11, prevent it from falling off from filter chamber
To sum up, by the way that connector 7 to be threaded on valve body 8, the connector 7 of different model can be replaced according to need, so as to even
Various sizes of adapter tube is connect, applicability is wide, in addition to this, moreover it is possible to control feed liquor flow, there is good using effect.Even if connecing
First 7 damage, the cost of replacement is also cheaper, saves the use cost of enterprise.
