Specific embodiment

Refer to Fig. 1 to Fig. 8, check (non-return) valve, including body portion, valve element 10 and spring 20.This body portion includes valve body 30 and valve seat 40.This valve body sets up pipelined channel 50 separately, valve element 10 can be slidably connected at body portion and can in open position and Slide to coordinate pipelined channel 50 between closed position, spring 20 is connected between valve element 10 and body portion.As Fig. 7 and Fig. 8 Shown, so that valve element 10 is slided and compression spring 20 to open position direction along pipelined channel forward direction flow action in valve element 10, such as Shown in Fig. 6, when reverse flow or pass water, valve element 10 is subject to spring 20 elastic force effect activity to closed position and valve element 10 sealed valve body Part with close pipelined channel 50 realize non-return.

Refer to Fig. 1 to Fig. 8, this valve body sets up the spaced apart fixing rib 41 of some annular arrays, some fixations separately The side towards annular axis of rib 41 has the conical surface 411, away from from closed position to open position between the conical surface 411 and annular axis Put gradually little arrangement, such as taper seat arrangement；The side towards annular axis having fixing rib 41 also has the alignment conical surface 411 and is located at Spigot surface 412 on the conical surface 411, away from equal to open position from closed position between this spigot surface and annular axis, this is led It is more than the maximum radius that the conical surface 411 is directed to annular axis to the radius of face opposed annular axis.

This valve element 10 has the slide bar 11 that a valve core head and that can seal cooperation body portion is fixed in valve core head, this valve Core print includes one and is fixed in valve core case 12 and a sealing ring 13 being socketed in outside valve core case 12 on slide bar 11, and this slide bar 11 is solid It is connected on the axial location of the end face of valve core case 12.

The annular of this some fixing rib 41 arrangement surrounds valve core head, the valve core head of valve element 10 and the conical surface 411 of valve element 10 Cooperation can be abutted against, so that the conical surface can play guide effect, play the effect supporting sealing ring, prevent sealing ring under high pressure-temperature It is rushed out it is ensured that valve element can smoothly reach operating position.

In one concrete structure, this valve seat 40 includes base 42 and retainer ring 43, sets the chute that axis runs through in base 42 421, base 42 and retainer ring 43 pass through that above-mentioned fixing rib 41 is affixed, and fixing rib had both played spoke effect, played reinforcement valve Seat intensity effect, plays above-mentioned guiding, supporting role again.It is fixed in base 42 to some fixing rib 41 annular space arrangements Outer peripheral face, retainer ring 43 is fixed in the side of the dorsad annular axis on several fixing rib 41 tops, such as fixing rib 41 it Top surface and fixing top surface of ring flush, and retainer ring is higher than the conical surface.This valve body 30 ringwise structure, valve body 30 and retainer ring 43 are fixed in Together, this is affixed such as: valve body 30 adaptation is fixed by socket ring 43, and retainer ring 43 outer peripheral face is arranged with draw-in groove 431, valve body 30 inner peripheral surface Projection fastener, this fastener snaps in draw-in groove, and the two is fixed together, and preferably, sets step, retainer ring 43 at valve body 30 Place sets step, and the two adaptation is with positioning convenient for assembly.This valve body 30 endoporus, retainer ring 43 endoporus and every adjacent two fixing ribs 41 Interval constitute pipelined channel 50.

The inside projection in top of this valve body 30 becomes sealing edge 31, the sealing ring 13 of this valve core head and sealing edge 31 to coordinate with logical Cross sealing ring 13 contact sealing edge 31 and realize sealing, realize non-return.

This slide bar 11 is slidably connected the chute 421 of base 42.This spring 20 is socketed slide bar 11 and contact is in valve core case 12 He Between base 42.Preferably, this base 42 external diameter is more than spring 20 external diameter.

Also it is socketed with an exterior seal ring 32 outside this valve body.

The above, only the utility model preferred embodiment, therefore the utility model enforcement can not be limited according to this Scope, the equivalence changes made according to the utility model the scope of the claims and description and modification, all should still belong to this practicality new In the range of type covers.
