Abstract
The utility model discloses a kind of novel cutoff valve, including valve body, bonnet, valve rod, handle, inlet channel and outlet conduit, flap is provided with the valve rod, the inlet channel end is provided with ball, and the ball two ends are rolled and are connected on inlet channel end side wall, and the cambered surface matched with ball is bent to form below the flap, the inlet channel end side wall is coated with colored paint with being provided with the side wall of ball and valve flap contacts on wearing layer, the valve rod.The utility model greatly protects flap and valve rod, extends the service life of stop valve, while the switch conditions of staff's valve can be reminded.
Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of novel cutoff valve.
Background technology
Stop valve is also known as pipe valve valve, belongs to forced seal formula valve；The opening and closing element of stop valve is the flap of stopper, sealing
Face is in plane or the extra large conical surface, and flap is for linear motion along the center line of valve seat.The forms of motion of valve rod has lifting rotation rod-type,
It is various types of available for the empty gas and water of control, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium etc.
The flowing of type fluid.Therefore, such stop valve valve that dams is highly suitable as cutting off or the use that adjusts and throttle.
But, flap and valve rod in existing stop valve often easily loosen or are worn and cause stop valve to leak, influence cut-off
The service life of valve.
In the connecting line of multi-pipeline valve, it can not quickly judge which valve, either with or without opening, is being looked for sometimes
During seeking valve, delay worker-hours, influence work task efficiency.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of novel cutoff valve, and the stop valve is greatly protected
Flap and valve rod, extend the service life of stop valve, while the switch conditions of staff's valve can be reminded.
To meet above-mentioned requirements, the technical solution of the utility model is：Including valve body, bonnet, valve rod, handle, water inlet pipe
Flap is provided with road and outlet conduit, the valve rod, the inlet channel end is provided with ball, and the ball two ends are rolled
It is connected on inlet channel end side wall, the cambered surface matched with ball, the inlet channel is bent to form below the flap
End side wall is coated with colored paint with being provided with the side wall of ball and valve flap contacts on wearing layer, the valve rod.
The wearing layer is tungsten carbide coating.
The beneficial effects of the utility model are：The utility model greatly protects flap and valve rod, extends stop valve
Service life, while the switch conditions of staff's valve can be reminded.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of novel cutoff valve as shown in Figure 1, including valve body 1, bonnet 2, valve rod 3, handle 4, inlet channel 6 and outlet pipe
Flap 5 is provided with road 7, the valve rod 3, the end of inlet channel 6 is provided with ball 8, and the two ends of ball 8 roll connection
On the end side wall of inlet channel 6, the lower section of flap 5 is bent to form the cambered surface matched with ball 6, the inlet channel 6
It is provided with the side wall that end side wall is contacted with ball 8 and flap 5 on wearing layer 9, the valve rod 3 and is coated with colored paint.
The wearing layer 9 is tungsten carbide coating.
On the one hand the design of the utility model ball 8 can stop flap 5, prevent from it from excessively moving down to influence to cut
Only the tight ness rating of valve, the purpose of buffering hydraulic pressure on the other hand can be played when opening stop valve, current is not directly impacted
Flap 5 but the flow chamber that the both sides of valve rod 3 are flowed to by the gap between ball 8 and the side wall of inlet channel 6, protect valve rod 3 and valve
Valve 5.
Valve of the present utility model can help staff by coating the eye-catching colored paint of a section color on valve rod 3
Quickly judge the valve whether there is opening.Wherein it is noted that the position of the coating of coating should be met, applied when valve is closed
Material does not appear, and valve can be easily seen painting color when opening.
