Face is vertical.It is relatively short that valve rod opens or closes stroke, and has very reliable cutoff action, so that this valve is very suitable
Cooperation uses for the cutting or adjusting and throttling of medium.
Filler is likely to occur the situation that filler is fallen into valve body cavity after use in the shut-off valve used now, so as to cause
The obstruction of valve body cavity.Therefore, those skilled in the art provide a kind of welding type stop valve, to solve to mention in above-mentioned background technique
Out the problem of.
Summary of the invention
The purpose of this utility model is to provide a kind of welding type stop valves, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions:
A kind of welding type stop valve, including valve body, the valve body inside upper part is provided with filled with filler, under the filler
Side is provided with Packing seat, filler pressing sleeve is provided on the upside of the filler, the filler pressing sleeve upper end is arranged on the outside of valve body, and fills out
Material pressing sleeve is fastenedly connected by hexagon thin nut and valve body, and the hexagon thin nut is set in the outside of filler pressing sleeve, the valve
It is provided with hand lever on the upside of body, valve rod is provided in the middle part of the hand lever lower end, and the hand lever inner right side is equipped with interior hexagonal and puts down
Holding screw is held, the left end of the interior hexagonal flush end holding screw and valve stem contacts, the valve rod lower end are each passed through filler pressure
Set, filler and Packing seat and valve rod lower end, which are located in valve body, is equipped with flap.
As a further solution of the present invention: the valve body left end is provided with medium entrance, in the valve body right end
Portion is provided with media outlet.
Connection is offered between medium entrance and flap in the valve body as a further solution of the present invention,
Kong Yi.
Connecting hole two is offered between the media outlet and flap as a further solution of the present invention, and
The section of media outlet is trapezoidal.
It is threadedly coupled between the filler pressing sleeve and valve rod as a further solution of the present invention,.
Compared with prior art, the utility model has the beneficial effects that
The utility model is simple in sturcture, ingenious in design, and the Packing seat being arranged on the downside of filler can prevent the whereabouts of filler from falling into
In valve body, choke valve body, while the leakproofness between filler and valve rod is also increased, keep leakproofness when valve working stronger.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of welding type stop valve.
In figure: 1- valve body, 2- flap, 3- valve rod, 4- Packing seat, 5- filler, 6- filler pressing sleeve, 7- hexagon thin nut, 8-
Hexagonal flush end holding screw in hand lever, 9-.
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.
Referring to Fig. 1, in the utility model embodiment, a kind of welding type stop valve, including valve body 1,1 inside of valve body
Top is provided with filled with filler 5, is provided with Packing seat 4 on the downside of the filler 5, is provided with filler pressing sleeve on the upside of the filler 5
6,6 upper end of the filler pressing sleeve setting is in 1 outside of valve body, and filler pressing sleeve 6 is fastenedly connected by hexagon thin nut 7 with valve body 1,
The hexagon thin nut 7 is set in the outside of filler pressing sleeve 6, is provided with hand lever 8 on the upside of the valve body 1, in 8 lower end of hand lever
Portion is provided with valve rod 3, and 8 inner right side of the hand lever is equipped with interior hexagonal flush end holding screw 9, the interior hexagonal flush end tightening
The left end of screw 9 is contacted with valve rod 3, and 3 lower end of valve rod is each passed through filler pressing sleeve 6, filler 5 and Packing seat 4 and valve rod 3
Lower end, which is located in valve body 1, is equipped with flap 2.
1 left end of valve body is provided with medium entrance, is provided with media outlet in the middle part of 1 right end of valve body.
Connecting hole one is offered between medium entrance and flap 2 in the valve body 1.
Connecting hole two is offered between the media outlet and flap 2, and the section of media outlet is trapezoidal.
It is threadedly coupled between the filler pressing sleeve 6 and valve rod 3.
The working principle of the utility model is:
When utility model works, rotate hand lever 8, hand lever 8 rotates in filler pressing sleeve 6 with ovable valve stem 3, valve rod 3 with fill out
