Also reservedly bottom described valve rod be provided with two non-through through holes to realize two-bit triplet function.
Described outer connection mechanism is provided with fast connector assembly, can realizes rapidly connecting and cut-offfing, also can join other link easily.
Described valve body top is provided with metalwork, realizes Z axis location.
Described valve rod top is provided with groove, and groove is provided with seal ring, realizes zero cut-offfing to full flow of current or air-flow both direction when valve rod rotates.
Described lower portion thereof is coupling in the top of described valve rod, and described handle is also provided with screw, and described screw is connected with the valve rod of bottom through handle, and described screw top is also provided with rubber parts.
Implement the embodiment of the present invention, there is following beneficial effect:
The two ends, left and right of this hand valve of the embodiment of the present invention can the outside thread of assembly connection or internal thread according to actual needs, it is the most simply fast inserting structure, comprise button, zinc cover, reed, pressure ring and seal ring, can directly insert or extract fast the flexible pipe (material is PU/PE/ nylon etc.) of corresponding external diameter, as long as tube outer diameter is in certain limit, no matter internal diameter is how many, and compression is how many, do not affect sealing, wide adaptability.
Plastics handle directly connects a plastics valve rod, and the through hole of this valve rod direction with good grounds specification flow determination size, Vertical direction two sides respectively has one close to the square female parts being greater than through hole, and a diaphragm seal is respectively installed on two sides.When hand valve cuts out, the turnover through hole of valve body blocked by the diaphragm seal on valve rod two sides, and the through hole of rotatable handle then on valve rod connects the turnover through hole of valve body gradually with angle, and the valve that makes to go smoothly can be opened gradually.Handle can rest on arbitrary position because of the frictional force of diaphragm seal, and the flow of hand valve can from zero to full flow.
All around being determined by plastics valve body of valve rod, is pressed with metalwork above and realizes Z axis location, and metalwork is then accurate embeds plastics valve body.The lower part coupling valve rod of plastic handle, determines all around, then links together with one piece of plain screw and valve rod.Consider attractive in appearance and corrosion protection, embedding one piece of rubber parts again on screw.
Be more than 2/2-way function, if want two-bit triplet (to pneumatic system), valve rod reserved itself two non-all-pass in hole, as long as fan the air them with drilling machine before assembling.When such hand valve cuts out, pressurized air can be discharged near handle then to air from active chamber.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment of the present invention water and gas dual-purpose hand valve, as Figure 1-5, comprise valve body 1, be arranged on the mangetic core assembly 2 of valve body 1 inside and the handle 3 on mangetic core assembly 2 top is set, inner chamber 4 through before and after valve body 1 inside is provided with, inner chamber 4 both sides are used for exterior tubing joint is provided with outer connection mechanism 11, mangetic core assembly 2 comprises valve rod 5 and diaphragm seal 6, through hole 7 through before and after bottom valve rod 5, a direction being provided with, being respectively arranged with cross section with the both sides of the axial Vertical direction of through hole 7 bottom valve rod is square female parts 8, the area of female parts 8 is greater than the cross section of body cavity through hole, diaphragm seal 6 is arranged in female parts 8, also reservedly bottom valve rod 5 be provided with two non-through through holes, handle 3 bottom is coupling in the top of valve rod 5, handle 3 is also provided with screw 9, screw 9 is connected with the valve rod 5 of bottom through handle 3, screw 9 top is also provided with rubber parts 10, valve body 1 top is provided with metalwork 12, by being arranged on groove on valve body 1 and valve rod is limited to above-below direction by metalwork metal ring, can only rotate, realize the location of Z axis, valve rod 5 top is provided with groove, groove is provided with seal ring, zero cut-offfing to full flow of current or air-flow both direction is realized when valve rod 5 rotates.
The two ends, left and right of this hand valve of the present embodiment can the outside thread of assembly connection or internal thread according to actual needs, it is the most simply fast inserting structure, comprise button, zinc cover, reed, pressure ring and seal ring, can directly insert or extract fast the flexible pipe (material is PU/PE/ nylon etc.) of corresponding external diameter, as long as tube outer diameter is in certain limit, no matter internal diameter is how many, and compression is how many, do not affect sealing, wide adaptability.
Plastics handle directly connects a plastics valve rod, and the through hole of this valve rod direction with good grounds specification flow determination size, Vertical direction two sides respectively has one close to the square female parts being greater than through hole, and a diaphragm seal is respectively installed on two sides.When hand valve cuts out, the turnover through hole of valve body blocked by the diaphragm seal on valve rod two sides, and the through hole of rotatable handle then on valve rod connects the turnover through hole of valve body gradually with angle, and the valve that makes to go smoothly can be opened gradually.Handle can rest on arbitrary position because of the frictional force of diaphragm seal, and the flow of hand valve can from zero to full flow.
All around being determined by plastics valve body of valve rod, is pressed with metalwork above and realizes Z axis location, and metalwork is then accurate embeds plastics valve body.The lower part coupling valve rod of plastic handle, determines all around, then links together with one piece of plain screw and valve rod.Consider attractive in appearance and corrosion protection, embedding one piece of rubber parts again on screw.
Be more than 2/2-way function, if want two-bit triplet (to pneumatic system), valve rod reserved itself two non-all-pass in hole, as long as fan the air them with drilling machine before assembling.When such hand valve cuts out, pressurized air can be discharged near handle then to air from active chamber.
Above disclosedly be only a kind of preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
