Abstract
The utility model belongs to the technical field of the valve technique and specifically relates to a cooling right -angle type stop valve of industry. A cooling right -angle type stop valve of industry, includes disk seat, valve gap and valve rod, valve gap and disk seat pass through square flange joint, the flange gasket that has sealed usefulness between valve gap and the disk seat, what the disk seat had a perpendicular setting advances tub body and exit tube body, advances that the cooperation is provided with the valve clack between tub body and exit tube body, is connected with the valve rod on the valve clack perpendicularly, and the hand wheel is connected on the top of valve rod, and outer and valve rod contact department of valve gap is equipped with the valve rod cover. This right -angle type stop valve cooperation is inseparabler, and the leakproofness is stronger, is particularly useful for the industry refrigeration.
Description
Technical field
The utility model relates to valve technology field, especially a kind of industrial refrigeration right-angle type stop valve.
Background technique
Stop valve belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.When medium is by when entering valve pocket below flap, the resistance overcome needed for steering force is the thrust that the frictional force of valve rod and filler and the pressure of medium produce, the power of the force rate valve opening door of closing valve is large, so the diameter of valve rod wants large, otherwise the fault of valve rod bending can occur.After occurring from self-packing valve, the MEDIA FLOW of stop valve enters valve pocket to just changing by above flap, and at this moment under pressure medium effect, the power of closing valve is little, and the power of valve opening door is large, and stem diameter can correspondingly reduce.Meanwhile, under medium effect, the valve of this form is also comparatively tight, namely very high to the requirement of sealing.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of industrial refrigeration right-angle type stop valve met sealing demand.
The utility model solves the technological scheme that its technical problem adopts: a kind of industrial refrigeration right-angle type stop valve, comprise valve seat, valve gap and valve rod, described valve gap is connected by square flange with valve seat, there is between valve gap and valve seat the flange gasket of sealing, described valve seat has vertically disposed inlet pipe body and goes out pipe body, inlet pipe body and go out between pipe body to be equipped with flap, flap is vertically connected with valve rod, the top of valve rod connects handwheel, and outside valve gap and valve stem contacts place is provided with valve stem casing.
Further, in described inlet pipe body, be provided with sealing surface of seat, described in go out in pipe body to be provided with valve seat effluent mouth.
The beneficial effects of the utility model are: this right-angle type stop valve coordinates tightr, and sealing is stronger, is particularly useful for industrial refrigeration.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve seat, 2. valve gap, 3. valve rod, 4. square flange, 5. flange gasket, 6. inlet pipe body, 7. goes out pipe body, 8. flap, 9. handwheel, 10. valve stem casing, 6.1. sealing surface of seat, 7.1 valve seat effluent mouths.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of industrial refrigeration right-angle type stop valve, comprise valve seat 1, valve gap 2 and valve rod 3, valve gap 2 is connected by square flange 4 with valve seat 1, has the flange gasket 5 of sealing between valve gap 2 and valve seat 1, and valve seat 1 has vertically disposed inlet pipe body 6 and goes out pipe body 7, inlet pipe body 6 and go out between pipe body 7 to be equipped with flap 8, flap 8 is vertically connected with valve rod 3, and the top of valve rod 3 connects handwheel 9, and outside valve gap 2 and valve rod 3 contacting point is provided with valve stem casing 10.
Further, in inlet pipe body 6, be provided with sealing surface of seat 6.1, go out in pipe body 7 to be provided with valve seat effluent mouth 7.1.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
