Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1 ~ 4, be multiple flow passages communicating valve provided by the utility model a preferred embodiment, including valve body 1, It is mounted on the outer cover 2 of 1 one end of valve body, forms delivery chamber 3 between valve body 1 and outer cover 2,1 center of valve body is equipped with reversing valve core Component, the reversing valve core component include the control-rod 4 for being interspersed in 1 center of valve body an of loose fit, are mounted on delivery chamber 3 Reversing valve core 5 that is interior and being able to rotate in the drive of control-rod 4.The valve body 1, which opens up, can be connected to 1 external world of valve body and delivery chamber 3 Upper channel 6, lower channel 7 and prepass 8, reversing valve core 5 is at position corresponding with upper channel 6, prepass 8 along control 4 bars axially penetrate through the upper through-hole 9 of setting and front through hole 10, and reversing valve core 5 is at the position of corresponding lower channel 7 along reversing valve core 5 circumferential direction opens up the Oil Guide groove body 11 an of arc backward, and the corresponding central angle of arc length of the Oil Guide groove body 11 is greater than 90 °. The circular arc where Oil Guide groove body 11 is passed through at the center of the upper through-hole 9 and front through hole 10.

Specifically, the control-rod 4 has the operating side 12 stretched out outside valve body 1, the operating side 12 of control-rod 4 is installed There is the positioning sleeve 13 being fixedly connected with valve body 1.Caulking groove 14, the installation of 13 inlay card of positioning sleeve is arranged far from one end of outer cover 2 in valve body 1 In the caulking groove 14.Positioning sleeve 13 in face of valve body 1 one end open up there are four commutate locating slot 15, the commutation locating slot 15 It is distributed on a circumference and is respectively corresponded with upper channel 6, lower channel 7 and prepass 8, valve body 1 is facing the one of positioning sleeve 13 Four mounting grooves 16 corresponding with commutation locating slot 15 are arranged in end, are fixed with spring 17 in the mounting groove 16, spring 17 is close One end of commutation locating slot 15 is equipped with positioning ball 18, and the diameter of positioning ball 18 is greater than the aperture of the commutation locating slot 15.? In the present embodiment, commutation locating slot 15 is the cylindrical groove axially extending along control-rod 4, can also will be described when actual implementation Commutation locating slot 15 is arranged along the cone tank that control-rod 4 axially opens up.Handle can be installed on control-rod.

The communication direction that gas circuit is understood in order to facilitate the operation of person, can also be further in the operating side of the control-rod 4 It is provided at least two orthogonal instruction blocks 19 for being used to indicate gas circuit.Certainly, it recognizes, can also indicate for convenience It paints on block 19.Preferably, the junction setting one of the sealed connection that can be dismantled between valve body 1 and outer cover 2, valve body 1 and outer cover 2 Enclose sealing ring 20.When it is implemented, can also be equal with upper through-hole 9, the diameter of front through hole 10 by the width of Oil Guide groove body 11, such as The reason of this setting, is, since Oil Guide groove body 11 and upper through-hole 9, front through hole 10 are all distributed on the same circumference, by Oil Guide groove body 11 width is arranged to equal with upper through-hole 9, the diameter of front through hole 10, facilitates molding, and can ensure reversing valve core 5 everywhere Intensity having the same, structural stability are strong.

In the state that attached drawing 1 ~ 4 is shown, upper through-hole 9 is sent chamber 3 with front through hole 10 and is connected to form gas circuit；User behaviour Make that when turning to the position opposite with front through hole 10 with upper through-hole 9 of Oil Guide groove body 11, conducting can be formed after control-rod 4 rotates Oil circuit, rotation control rod 4 is further continued for, so that the oil liquid in Oil Guide groove body 11 is rotated conveying, when reaching Oil Guide groove body 11 When being connected to lower channel 7, oil liquid is conveyed out valve body 1.That is, multiple flow passages communicating valve described in the utility model and can be with Gas is conveyed, the conveying of liquid can also be carried out, certainly, rotation control rod 4 to upper channel 6 and Oil Guide groove body 11 are opposite, and lead When oil groove body 11 is not opposite with prepass 8, gas circuit is blocked.By above to the description of the utility model it is found that and the prior art The function that can realize commutation connection by the design of simple structure compared to multiple flow passages communicating valve described in the utility model, will The conveying of gas and liquid is integrated into a valve body and carries out, and design is simple, and good positioning effect is easily installed, adjusts.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
