The greasing channel is connected to the intracorporal pipeline of ball valve；
Spring is arranged in the greasing channel；
Steel ball is arranged in the greasing channel, contacts with spring；It is realized by the steel ball and blocks greasing connector
First end；
The ball-and-seat first end connects grease filling machine, and ball-and-seat second end is connect with greasing connector second end；Grease filling machine
Stop-leak compound passes through ball-and-seat respectively and greasing connector flows into ball valve body；And the intracorporal fluid of ball valve cannot pass through greasing and connect
Head is flowed out from ball-and-seat.
The greasing joint body first end is equipped with screw thread, is connect by the screw thread with ball valve body.
An interior step is equipped in the greasing channel, greasing channel is divided into of different sizes two sections by the interior step；
Greasing channel first segment is connected to greasing joint body first end end face；Greasing channel second segment is connected to greasing joint body second end
End face；Greasing channel first segment is wider than greasing channel second segment.
The spring is arranged in the first segment of greasing channel.
The steel ball is arranged in the first segment of the greasing channel, and between the spring and the interior step, leads to
The elastic force for crossing spring transmitting resists interior step end face；The size of steel ball matches greasing channel first segment internal diameter.
Detailed description of the invention
In order to illustrate more clearly of technical solutions of the utility model, letter will be made to attached drawing needed in description below
Singly introduce, it should be apparent that, the accompanying drawings in the following description is one embodiment of the utility model, skill common for this field
For art personnel, without creative efforts, it is also possible to obtain other drawings based on these drawings:
Fig. 1 is the grease pouring device schematic diagram of the utility model；
Fig. 2 is greasing connector schematic diagram of internal structure.
In figure: 1, greasing joint body first end；2, greasing joint body second end；3, spring；4, steel ball；5, greasing connects
Head；6, greasing channel；7, interior step；8, ball-and-seat.
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.
In order to achieve the above object, the utility model provides a kind of novel grease pouring device, is mounted on ball valve, such as Fig. 1
It is shown, it include greasing connector 5 and ball-and-seat 8；
As shown in Fig. 2, the greasing connector 5 includes:
Greasing joint body, the greasing joint body first end 1 are equipped with screw thread, are connected by the screw thread and ball valve body
It connects, the greasing joint body second end 2 is arranged outside ball valve body of laws；It is equipped with and passes through along central axis direction inside greasing joint body
Wear the greasing channel 6 of the ontology；The greasing channel 6 is connected to the intracorporal pipeline of ball valve；It is set in greasing channel 6
There is an interior step 7, it is of different sizes two sections that greasing channel 6 is divided to by the interior step 7；6 first segment of greasing channel is wider than note
6 second segment of rouge channel；6 first segment of greasing channel is connected to 1 end face of greasing joint body first end；The connection of 6 second segment of greasing channel
2 end face of greasing joint body second end；
Spring 3 is arranged in 6 first segment of greasing channel；
Steel ball 4 is arranged in 6 first segment of greasing channel, and is arranged between the spring 3 and the interior step 7,
The size of steel ball 4 matches 6 first segment internal diameter of greasing channel；When stop-leak compound is flowed from the greasing channel 6 of greasing joint body second end 2
When entering greasing connector 5,4 compressed spring 3 of steel ball, stop-leak compound flows into 6 first segment of greasing channel, into the pipeline fortune inside ball valve body
Defeated system；After stopping greasing, steel ball 4 resists interior step 7 by spring 3, due to the size and 6 first segment of greasing channel of steel ball 4
