Abstract
The utility model relates to valve technology field, especially a kind of refrigeration plant right-angle type stop valve.A kind of refrigeration plant right-angle type stop valve, comprise valve seat, valve rod and bonnet, described valve seat have inlet pipe body and go out pipe body, inlet pipe body and go out between pipe body to be equipped with flap, flap connects valve rod, in valve stem tip, cover has bonnet, valve stem casing is provided with outside described valve rod, to coordinate bonnet, between described bonnet and valve stem casing, there is sealing configuration, sealing structure is upwards disposed with aluminium backing, graphite pads, O type circle and alumiseal bottom bonnet inner bore, and described valve stem casing and valve seat are bolted.This right-angle type stop valve coordinates tightr, and sealing is stronger, is particularly useful for refrigeration plant.
Description
Technical field
The utility model relates to valve technology field, especially a kind of refrigeration plant 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 refrigeration plant right-angle type stop valve met sealing demand.
The utility model solves the technological scheme that its technical problem adopts: a kind of refrigeration plant right-angle type stop valve, comprise valve seat, valve rod and bonnet, described valve seat have inlet pipe body and go out pipe body, inlet pipe body and go out between pipe body to be equipped with flap, flap connects valve rod, in valve stem tip, cover has bonnet, valve stem casing is provided with outside described valve rod, to coordinate bonnet, between described bonnet and valve stem casing, there is sealing configuration, sealing structure is upwards disposed with aluminium backing bottom bonnet inner bore, graphite pads, O type circle and alumiseal, described valve stem casing and valve seat are bolted.
Further, described O type circle is provided with two, 5 ~ 10mm of being separated by between two O type circles.
The beneficial effects of the utility model are: this right-angle type stop valve coordinates tightr, and sealing is stronger, is particularly useful for refrigeration plant.
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 rod, 3. bonnet, 4. inlet pipe body, 5. goes out pipe body, 6. flap, 7. valve stem casing, 8. aluminium backing, 9. graphite pads, 10.O type circle, 11. alumiseals, 12. bolts.
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 refrigeration plant right-angle type stop valve, comprise valve seat 1, valve rod 2 and bonnet 3, valve seat 1 have inlet pipe body 4 and go out pipe body 5, inlet pipe body 4 and go out between pipe body 5 to be equipped with flap 6, flap 6 connects valve rod 2, on valve rod 2 top, cover has bonnet 3, valve stem casing 7 is provided with outside valve rod 2, to coordinate bonnet 3, have sealing configuration between bonnet 3 and valve stem casing 7, sealing structure is upwards disposed with aluminium backing 8, graphite pads 9, O type circle 10 and alumiseal 11 bottom bonnet 3 endoporus, and valve stem casing 7 is connected by bolt 12 with valve seat 1.
Further, O type circle 10 is provided with two, 5 ~ 10mm of being separated by between two O type circles 10.
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.
