Abstract
The utility model provides a ball core plastic check valve for pipes with the advantages of firm connection, excellent sealing and easy assembly. The ball core plastic check valve for pipes comprises a valve body, a plastic pipe connected integrally with the valve body and a locknut connected with the valve body through a thread; the inside part and the outside part of the valve body are connected through a thread to form a valve body cavity; a ball valve core and a spring along the axis direction of the valve are arranged in the valve body cavity; one end of the spring is contacted with the valve core and the other end of the spring is connected onto a fixed block in the valve body cavity; the plastic pipe is clamped between the locknut and the inside part of the valve body; the inside part of the valve body is provided with a lengthened socket structure so that the valve and the plastic pipe are connected compactly and sealed excellently; and a zigzag locking ring and a seal ring are arranged between the inside part of the valve body and the locknut, thus further reinforcing the connecting firmness thereof. The ball core plastic check valve for pipes can be broadly applied for paving plastic pipes.
Description
Technical field
The utility model belongs to valve technology field, the safety check that particularly is connected with plastic tube.
Background technique
Because pipeline valve generally can not directly be connected with tubing through screw thread, need the special valve member and the connection set of plastic tube.
Chinese patent CN2566089Y discloses a kind of valve linkage structure of improvement; This linkage structure comprise valve body, with valve body connecting tube that is connected as a single entity and the nut that is connected with valve body through screw thread; One retaining edge is arranged on the inner side surface of nut outer end; A joint for plastic tube passes nut, and the outer side surface that pipe joint inserts the nut part is provided with an annular convex shoulder, and retaining is along being buckled on the annular convex shoulder; There is an intilted inclined-plane connecting tube end, is provided with a seal ring that is socketed on the aforementioned tube joint between this inclined-plane and the annular convex shoulder.This Placement is utilized the wedging principle, and the continuous crush seal circle in inclined-plane arrives good sealing effect, and still, the lasting moment that this extruding brings can reduce the working life of seal ring, and then influences sealing effect.
Summary of the invention
The utility model provides a kind of and is connected firmly, good seal, the effective ball core plastic check damper that is easy to assemble.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of effective ball core plastic check damper is provided, comprise valve body, with valve body plastic tube that is connected as a single entity and the locking nut that is connected with valve body through screw thread, valve body is made up of valve body inside part and valve body external lateral portion; Valve body inside part and valve body external lateral portion formation form the valve body chamber through being threaded; Be provided with spherical spool in the valve body chamber and along the spring of valve axis direction, spring one end in contact spool, an end are connected on the endoceliac fixed block of valve; Plastic tube is clamped between locking nut and the valve body inside part; Said valve body inside part has the lengthening bell and spigot frame, and it is compact that valve is connected with plastic tube, good seal; Be provided with flexuose clamp ring and seal ring between said valve body inside part and the locking nut, further strengthen the soundness of its connection.
Further, the inboard of said valve body inside part is provided with four muscle and prevents that spherical spool from producing slip, and the end face of valve body inside part is realized the function of safety check better to the spool soft seal.
Further, the inboard of said valve body external lateral portion is provided with the matrix draw-in groove and matches with the concave slot of fixed block, prevents that spring from walking.
The beneficial effect of the utility model is following:
1, the mode that adopts FERRULETYPE lengthening bell and spigot frame and flexuose clamp ring to match has very high Drop-proof property and join strength.
2, internal structure adopts the ball core of soft seal to increase the performance that recoil of spring resets fast when liquid flows backwards, and the utility model can horizontal or vertically be installed, and is applied widely.
Description of drawings
Fig. 1 is that the utility model is connected schematic representation with tubing;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation: a kind of effective ball core plastic check damper; The plastic tube 1 and the locking nut that is connected with valve body through screw thread 2 that comprise valve body, be connected as a single entity with valve body; Valve body inside part 5 forms the valve body chamber with valve body external lateral portion 10 through being threaded; Be provided with spherical spool 6 in the valve body chamber and along the spring 7 of valve axis direction, spring 7 one end in contact spools 6, one ends are connected on the endoceliac fixed block 9 of valve; Plastic tube 1 is clamped between locking nut 2 and the valve body inside part 5; Valve body inside part 5 has lengthening bell and spigot frame 5a, is provided with flexuose clamp ring 3 and seal ring 4 between valve body inside part 5 and the locking nut 2, inclined-plane, the clamp ring 3 two ends stress deformation cylindrical of killing plastic tube 1 tightly.
As shown in Figure 2, valve body inside part 5 inboards are provided with four muscle 5d, and its end face 5c is to the spool soft seal.Valve body external lateral portion 10 inboards are provided with matrix draw-in groove 10a and match with the concave slot 9a of fixed block 9.
When supplying water, back down into water to spherical spool 6 through hydraulic pressure; As when stopping to supply water, under spring 7 active forces, spherical spool 6 being resetted to reach prevents counter flow action.
