Embodiment
Now the utility model is described in further detail with specific embodiment by reference to the accompanying drawings.
As shown in Figure 1, safety check described in the utility model, comprises valve body 11, telescopic baffle 12, return spring 13, spool 14, fixed block 15 and valve gap 16.
Valve body 11 is provided with a cylindrical cavity 17, and valve body 11 is provided with for being communicated with extraneous import with inner chamber 17 and outlet, and import and outlet are all circular port; Import and outlet are positioned at the two ends of described inner chamber 17.It is columned feed liquor pipeline section 18 that shape in one section of pipe is extended in import; The diameter of feed liquor pipeline section 18 is less than the diameter of cylindrical cavity 17.
Fixed block 15 is fixedly installed on inner chamber 17, and inner chamber 17 is separated into two-part, and import and outlet are positioned at the both sides of fixed block 15; Fixed block 15 is disk fixed block 15, is provided with an installation through hole and is circumferentially uniformly distributed the small through hole (being namely communicated with opening and import) of the inner chamber 17 being provided with six circular connection fixed block 15 both sides in the middle part of it.The concrete mounting type of disk fixed block is as follows: on the wall of inner chamber 17, be provided with a circle draw-in groove, and the outer side wall of disk fixed block is provided with a circle buckle, and disk fixed block is arranged in inner chamber 17 by buckle and draw-in groove clamping.
Spool 14 is fixedly installed on installation through hole.One end of return spring 13 is fixedly installed telescopic baffle 12, and telescopic baffle 12 and return spring 13 are pressed between fixed block 5 and import, and the other end of return spring 13 is close to spool 14.Telescopic baffle 12 is cylinder type, and the diameter of telescopic baffle 12 is greater than the diameter of import; Telescopic baffle 12 covers described import.In order to make return spring 13 can not move in radial direction, return spring 13 Placement another kind of with the employing of spool 14, be specially: spool 14 extends fixed block 15, it is outside that return spring 13 is set in described spool 14.
Valve gap 16 is circular, and namely valve gap 16 is provided with and is communicated with water port that is extraneous and inner chamber 17, and valve gap 16 is arranged on outlet.
Application principle of the present utility model: as shown in Figure 2, safety check is arranged on the bottom of material pipe 3, the mounting type of safety check is that liquid is entered by the import of safety check, exported out; Material pipe 3 and safety check are put into barrel 2 from the opening of barrel.When the pump housing 4 starts, safety check is telescopic baffle 12 compression retracteding position spring 13 under hydraulic pressure, i.e. safety check valve open, liquid charging stock enters safety check, liquid charging stock by six small through hole of disk fixed block, the outlet of safety check, thus enters feeding pipe 3, finally takes out stream and enters raw material storage tank; Stop when the pump housing 4 runs, telescopic baffle 12 resets under the promotion of return spring 13, again covers import and namely shuts import, and then avoid the backflow of liquid.
Safety check described in the utility model, simple and ingenious structure and the function of " non-return " anti-back flow can be realized well.Because the water port of valve gap 16 and the small through hole of disk fixed block 15 all ensure that liquid is smooth by safety check; Feed liquor pipeline section 18 is that liquid has a minibuffer when entering safety check, makes the flowing of liquid more smooth.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and variation.
