The outer silk of above-mentioned single loose joint ball check valve, wherein, the outer wall of described outlet part end is provided with outside thread; The nearly outlet part end of described adapter is provided with step; The outer end of described coupling nut is provided with inside flange, and its inner side is provided with internal thread; During use, described coupling nut is set in the described adapter, and its flange hooks the step of described adapter, and its internal screw-thread screw is connected as a single entity outlet part and adapter on the outside thread of outlet part end.
The outer silk of above-mentioned single loose joint ball check valve, wherein, described outlet part oral area is provided with a seal ring with the position that contacts.
The outer silk of above-mentioned single loose joint ball check valve, wherein, described adapter is provided with outside thread.
The outer silk of above-mentioned single loose joint ball check valve wherein, is provided with seal ring between the nozzle inner wall of described check valve body outer wall and prolongation non-return pipeline section.
The outer silk of above-mentioned single loose joint ball check valve wherein, also comprises a set screw nut, and described valve rod top is provided with outside thread, and described keying handle is provided with through hole; Described valve rod top is passed and is opened and closed the through hole that handle is provided with, and by set screw nut valve rod and keying handle is connected as a single entity.
Because the utility model has adopted above technological scheme, at the water outlet of ball valve the prolongation non-return pipeline section of one flexible connection is housed, and is provided with a safety check in the non-return pipeline section.The length of the environment timely adjustment pipe laying that can use according to the user, convenient for users.And have refluence when preventing that current from passing through valve body, play the effect of non-return.
Description of drawings
Concrete structure of the present utility model has following embodiment and accompanying drawing thereof further to provide.
Fig. 1 is a kind of embodiment's of the utility model a form structure schematic representation.
Fig. 2 is a kind of embodiment's of the utility model a structure sectional view.
Embodiment
See also Fig. 1.The outer silk of the utility model list loose joint ball check valve comprises valve body 1, is located at valve ball 2 in the valve body, is arranged on the seal washer 3 between valve body and the valve ball, the valve rod 4 that is connected with valve ball, is located at the valve gap 5 of valve body oral area, the keying handle 6 that is connected with valve rod.Present embodiment also comprises a set screw nut 7, and described valve rod top is provided with outside thread, and described handle is provided with through hole 61; Described valve rod top is passed and is opened and closed the through hole that handle is provided with, and by set screw nut 7 valve rod and keying handle is connected as a single entity.
One end of described valve body 1 is provided with inlet part 12, and the other end is provided with outlet part 13; Also comprise a prolongation non-return pipeline section 8 that flexibly connects, the prolongation non-return pipeline section 8 of described flexible connection is arranged on described outlet part end, and it comprises that an adapter 81 of docking with the outlet part oral area and is with outlet pipe with take over the coupling nut 82 connect as one.Being provided with a safety check 9 in the prolongation non-return pipeline section of described flexible connection, mainly is the refluence when preventing that current from passing through valve body, plays the effect of non-return.Be provided with seal ring 91 between the inwall of the adapter 81 of the valve outer wall of described safety check 9 and prolongation non-return pipeline section.
In the present embodiment, the oral area of described outlet part is provided with outside thread 131 outward.The nearly outlet part end of described adapter 81 is provided with step 811; The outer end of described coupling nut 82 is provided with inside flange 821, and the inwall of this coupling nut 82 is provided with internal thread 822; During use, described coupling nut is set in the described adapter, and its flange hooks the step of described adapter, and its internal screw-thread screw is connected as a single entity outlet part and adapter on the outside thread of outlet part end.
