Description
Technical field
The present invention relates to a kind of stop valve.
Background technology
The opening and closing element of stop valve is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along valve seat
Heart line is for linear motion, the forms of motion of valve rod, also has lifting rotation rod-type, and stop valve refers to closure member
The valve that (flap) moves along valve seat centrage, according to this mobile form of flap, valve seat port
Change is and flap stroke direct proportionality, and due to the valve rod of such valve, to be turned on and off stroke relative
Shorter, and there is cutting function very reliably, again due to change and the stroke of flap of valve seat port
Direct proportionality, is very suitable for the regulation to flow, therefore, such stop valve valve that dams
Door is highly suitable as cutting off or regulating and throttling use.
But stop valve is during regulation liquid, and the impurity carried in liquid can be deposited in bottom valve,
Valve is caused the irreversible damages such as corrosion, ultimately causes valve and damage, reduce service life.
Summary of the invention
The technical problem to be solved is to provide the stop valve of a kind of improvement, and simple in construction is permissible
Effectively filter out the impurity flowed through in stop valve in liquid, safe and reliable, add service life simultaneously,
Save cost.
For solving above-mentioned technical problem, the technical scheme is that
The stop valve of a kind of improvement, including valve body, described valve body is provided with adapter cavity, described adapter cavity both sides
Being respectively equipped with intake channel and exit passageway, described adapter cavity, intake channel is connected with exit passageway,
Wherein, described adapter cavity bottom is provided with drainage channel, and described drainage channel is cylindrical structural, described in draw
Circulation road is paralleled with exit passageway, and is oppositely arranged with exit passageway, is provided with solid in described drainage channel
Fixed plug, described fixing plug includes fixing plug main body, fixing plug end cap and filter element, and described fixing plug is main
Body is cylindrical structural, and fixing plug main body and drainage channel interference fit, described fixing plug end cap is cylinder
Shape structure, the diameter of fixing plug end cap is more than the diameter of fixing plug main body, and described fixing plug end cap is with fixing
Angle a and drainage channel between plug main body are equal with the angle b of vertical direction, described fixing plug end cap
Being integral type structure with fixing plug main body, described filter element includes filter frame and drainage screen, described filtration
Net is fixed on the lower section of described filter frame, and described filter frame is fixed in described fixing plug main body, described mistake
Filter frame is with carbon fiber as material.
The stop valve of above-mentioned a kind of improvement, wherein, is provided with one layer of filter membrane inside described exit passageway.
The invention have the benefit that
When the present invention uses, fixing plug is filled in drainage channel, now, by carbon fiber elastic material system
The filter frame and the drainage screen level that become are laid on bottom adapter cavity, open stop valve, make liquid flow
Logical, now, the impurity carried in liquid is just precipitated in the drainage screen of the nanofiber level bottom adapter cavity,
After time valve uses one section, closing valve, extract fixing plug, the impurity being deposited in drainage screen can be with
Fixing plug is carried over together, it is also possible to the liquid remained in valve is released valve in the lump, it is to avoid
Valve inwall is corroded by impurity or liquid, affects its sealing, thus adds making of stop valve
Use the life-span.
Fixing being provided with beyond the Great Wall fixes plug end cap, can realize being placed and taken out of fixing plug easily and fast,
Save manpower and materials, save resource.
State and inside exit passageway, be provided with one layer of filter membrane, serve the effect of filtration, it is possible to avoid further
Magazine is taken out of by liquid, then is cleared out by drainage screen.

Fig. 2 is A portion of the present invention enlarged drawing
Fig. 3 is that the present invention fixes plug structure figure
Detailed description of the invention
A kind of stop valve of improvement, including valve body 1, described valve body 1 is provided with adapter cavity 2,
Described adapter cavity 2 is respectively provided on two sides with intake channel 3 and exit passageway 4, described adapter cavity 2, and import is led to
Road 3 is connected with exit passageway 4, is provided with one layer of filter membrane 5, described mistake inside described exit passageway 4
Crossing bottom, chamber 2 and be provided with drainage channel 6, described drainage channel 6 is cylindrical structural, described drainage channel 6
Parallel with exit passageway 4, and be oppositely arranged with exit passageway 4, be provided with solid in described drainage channel 6
Surely filling in 7, described fixing plug 7 includes fixing plug main body 8, fixing plug end cap 9 and filter element 10, institute
Stating fixing plug main body 8 is cylindrical structural, fixing plug main body 8 and drainage channel 6 interference fit, described
Fixing plug end cap 9 is cylindrical structural, and the diameter d1 of fixing plug end cap 9 is straight more than fixing plug main body 8
Footpath d2, described fixing plug end cap 9 and the fixing angle a filled between main body 8 and drainage channel 6 are with vertical
The angle b in direction is equal, and described fixing plug end cap 9 is integral type structure with fixing plug main body 8, described
Filter element 10 includes that filter frame 11 and drainage screen 12, described drainage screen 12 are fixed on described filter frame
The lower section of 11, described filter frame 11 is fixed in described fixing plug main body 8, and described filter frame 11 is with carbon
Fiber is material.
When the present invention uses, fixing plug is filled in drainage channel, now, by carbon fiber elastic material system
The filter frame and the drainage screen level that become are laid on bottom adapter cavity, open stop valve, make liquid flow
Logical, now, the impurity carried in liquid is just precipitated in the drainage screen of the nanofiber level bottom adapter cavity,
After time valve uses one section, closing valve, extract fixing plug, the impurity being deposited in drainage screen can be with
Fixing plug is carried over together, it is also possible to the liquid remained in valve is released valve in the lump, it is to avoid
Valve inwall is corroded by impurity or liquid, affects its sealing, thus adds making of stop valve
Use the life-span.
Here description of the invention and application is illustrative, is not wishing to limit the scope of the invention to
Stating in embodiment, therefore, the present invention is not limited by the present embodiment, and any employing equivalence replacement obtains
Technical scheme is all in the scope of protection of the invention.
