Summary of the invention
The object of the invention is to improve in the structure of existing safety check, provide Long-Time Service also can not a kind of hand water pump check valve special of shutoff actual effect.
A kind of hand water pump check valve special of the present invention, there is valve body, influent stream mouth, go out head piece, runner, valve seat, occluding body, in described valve body, there is runner, described runner has the valve seat separated by runner, described valve seat has valve port, described occluding body matches with valve port, described influent stream mouth with go out head piece and be connected by runner, it is characterized in that described valve seat is the valve seat with boss and guard, described valve port is arranged in the boss top of valve seat and is nested with at guard, described boss wall is restrained to valve port one end, described occluding body is float-ball type occluding body, described float-ball type occluding body is arranged in valve port place and is nested with at guard.
Valve body described in the present invention can adopt existing one-part form valve body, also can be the multi-section type valve body of two or more, described adjacent valve body section is fixedly connected with, when adopting multi-section type valve body, the parts such as described valve seat can be allowed to be fitted in valve body by the later stage, manufacturing process is simplified.The influent stream mouth end of described valve body with go out head piece end and all can the interface being connected the water parts such as outer tube be set, certainly if desired, also the influent stream mouth end of valve body and the part that goes out head piece end can be allowed to serve as, as: on the outer wall of the influent stream mouth end of valve body and on the outer wall going out head piece end, spiral shell side is set respectively, on the inwall of the influent stream mouth end of valve body and on the inwall going out head piece end, screw thread etc. is set respectively.
Boss on valve seat described in the present invention can be the various structural type such as annular boss or rectangular boss, or even boss transverse section is irregular geometric figures, as long as described boss sidewall corral becomes tubular structure.Described boss wall is restrained to valve port one end, namely refer to that outer wall of boss or boss inwall narrow to described valve port (with capping abutting end), also can be that outer wall of boss and boss inwall narrow to described valve port place simultaneously, allow the surface of contact of described valve port and capping diminish, between namely usually said described valve port and capping, adopt linear contact lay.After arranging like this, the stop area of silt in the underground water extracted on the surface of contact of valve port and capping diminishes, even can not stop, contact with the face adopted between capping relative to the valve port of existing safety check, safety check of the present invention, sedimentation in underground water effectively can be prevented at valve port place, avoid safety check shutoff and lost efficacy.Valve seat described in the present invention is the valve seat with boss and guard, described valve port is arranged in the boss top of valve seat and is nested with at guard, described boss wall is to the convergence of valve port one end, and described occluding body is float-ball type occluding body, and described float-ball type occluding body is arranged in valve port place and is nested with at guard.Namely refer to that valve port and float-ball type occluding body are nested with wherein by the guard of valve seat simultaneously, the smooth shutoff valve port of float-ball type occluding body, guard not only can be allowed can also to limit ball float displacement when drawing water, and when preventing from not drawing water, ball float accurately aligned with port can not carry out shutoff.So, just can remove the hinge portion of existing capping from, and then it also avoid the hinged inefficacy of capping or cause because power of drawing water is excessive the problem that final capping cannot fall after rise.
When using safety check of the present invention, first the influent stream mouth of valve body can be fixedly connected with outside underground water water outlet, the head piece that goes out of valve body is fixedly connected with outside domestic hand water pump water intake, then when user shake domestic hand water pump underground water is drawn into ground time, the float-ball type occluding body at described valve port place is floated unlatching valve port with current and is limited in guard, and be in unidirectional opening state, underground water passes through smoothly, now, the silt carried secretly in underground water can along with water movement.When user stops shaking domestic hand water pump, now, underground water meeting natural subsidence, the silt carried secretly in underground water also can natural subsidence, current can drive float-ball type occluding body to fall after rise, and the falling direction of guard restriction float-ball type occluding body, allows it move to valve port place in this process, the silt being positioned at valve port place owing to there is no the position of position (large particle silt cannot stop) or the rare stop stopped, namely respectively along boss madial wall and the sedimentation of boss outer side wall of described valve seat.Even if there is a small amount of little sedimentation at valve port place, also the suction being enough to be produced by the underground water sedimentation located at this is taken away, meanwhile, the suction that underground water sedimentation produces also can allow described float-ball type occluding body fit with described valve port firmly, allows this faying surface be in sealing state.
