Arresting gear is combined with water out adapter, can effectively improve the operating efficiency of machine, is reduced production of machinery sheet, is improved pump
Service life, this structure is more readily produced manufacture, and more convenient in after-sale service.
Technical scheme is used by the utility model solves its technical problem：A kind of band is provided and closes going out for rifle stopping function
Water installations, including body and water inlet, one end of described body is water inlet, and connection water inlet and pipe are disposed with the body
The runner of the body other end, the middle part side of described body are connected with valve shell, and the inner upper end of described valve shell is inserted
Enter and valve body is installed, the interior central of described valve body has been vertically arranged valve rod, and the lower end of described valve shell passes through overflow
Mouth communicates with runner, and the lower end of described valve rod is the sealing shroud being close to inwall, and the lower end conical head of described valve rod will overflow
Head piece is blocked, and discharge outlet is disposed with the interior middle part of sliding channel of described valve body, and the upper end of described sealing shroud is disposed with bonnet, institute
The inside for the sealing shroud stated axially is disposed with limbers, the valve stem sleeve between the upper end of described bonnet and the inside top of valve body
Spring is connected to, the upper end of described valve rod is exposed in the upper surface of valve body.
Further, drainage interface seat, described discharge outlet and row are installed between two parties in the side wall of described valve shell
Water interface block is connected.
Further, it is clamped with sealing ring between valve shell in the middle part of the lower end of described valve body and side wall.
Further, described runner is bellmouth, and the one end being connected with water inlet is bigger diameter end.
Beneficial effect：The utility model is related to the discharging device that a kind of band closes rifle stopping function, will close rifle arresting gear with
Water out adapter is combined, and reduces production of machinery sheet, improves the service life of pump, and this structure is more readily produced manufacture,
The operating efficiency of pump is improved well.Traditional efficiency of pump is 85% or so, using the efficiency of pump improves afterwards after the present apparatus
7%, simple in assembling, maintenance does not have to tear pump open, directly changes joint, and cost is lower, more convenient in after-sale service.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As Figure 1-3, embodiment of the present utility model is related to the discharging device that a kind of band closes rifle stopping function, including
Body 1 and water inlet 2, one end of described body 1 is water inlet 2, and connection water inlet 2 is disposed with the body 1 and body 1 is another
The runner 3 of one end, the middle part side of described body 1 are connected with valve shell 4, and the inner upper end of described valve shell 4 is inserted
Enter to be provided with valve body 10, the interior central of described valve body 10 has been vertically arranged valve rod 11, and the lower end of described valve shell 4 leads to
Cross overfall 14 to communicate with runner 3, the lower end of described valve rod 11 is the sealing shroud 6 being close to inwall, described valve rod 11
Lower end conical head blocks overfall 14, and discharge outlet 13, described sealing are disposed with the interior middle part of sliding channel of described valve body 10
