Abstract
The utility model discloses a wear -resisting stop valve (NJ41Y), including stop valve body, hand wheel, valve rod, valve clack, the hand wheel pass through bolted connection on the valve rod, the valve rod in stop valve body swing joint together, valve clack and stop valve body contact surface between be equipped with the protective layer that is used for valve clack and stop valve body contact surface against abrasion, the protective layer be tungsten carbide coating, tungsten carbide coating scribble at valve clack and stop valve body contact surface, the wearing and tearing minimizing of effectual messenger's valve clack of tungsten carbide coating and stop valve body contact surface, the life of very effectual increase stop valve, the beneficial effects of the utility model are that, make the valve gap better with the sealed effect of ending between the valve body, wearing and tearing minimizing between them.
Description
Technical field
The utility model relates to a kind of stop valve, especially provides a kind of abrasion-resistant cut-off valve.
Background technique
Its major defect of existing stop valve is that medium directly washes away valve seat and valve clack sealing surface when opening and closing, washing away and wearing and tearing larger sealing surface, and valve rod sealing device be all generally arrange between valve rod with valve gap together with seal ring, medium easily leaks, poor sealing performance.
Model utility content
In order to overcome the larger shortcoming of existing stop valve sealing case wearing and tearing, the utility model provides a kind of abrasion-resistant cut-off valve, not only solves the deficiency of existing stop valve sealing, and makes the minimise wear between flap and valve body.
The utility model solves the technological scheme that its above-mentioned technical problem adopts: a kind of abrasion-resistant cut-off valve; include stop valve body, handwheel, valve rod, flap; described handwheel is bolted on valve rod; valve rod is movably connected in stop valve body, is provided with and prevents for flap and stop valve body contacts face the protective layer that weares and teares between described flap and stop valve body contacts face.Described protective layer is tungsten carbide coating.Described tungsten carbide coating is coated in flap and stop valve body contacts face.
The beneficial effects of the utility model are: make the sealing effect between valve gap and checking-valve body better, the minimise wear between them.
Accompanying drawing explanation
Further illustrate below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is the novel structural representation of the utility model.
Embodiment
A kind of abrasion-resistant cut-off valve as shown in the figure; include stop valve body, handwheel 2, valve rod 4, flap 6; described handwheel 2 is connected on valve rod 4 by bolt 1; valve rod 4 and stop valve body are movably connected, and be provided with and prevent for flap and stop valve body contacts face the protective layer 5 that weares and teares between described flap 6 and stop valve body contacts face.Described protective layer 5 is tungsten carbide coating.Described tungsten carbide coating is coated in flap 6 and stop valve body contacts face.Tungsten carbide coating effectively makes the minimise wear in flap and stop valve body contacts face, the working life of effectively increase stop valve, and the technical program is applicable to stop valve (NJ41Y).
Claims (3)
1. an abrasion-resistant cut-off valve; include stop valve body, handwheel, valve rod, flap; described handwheel is bolted on valve rod; valve rod is movably connected in stop valve body, it is characterized in that: be provided with between described flap and stop valve body contacts face and prevent for flap and stop valve body contacts face the protective layer that weares and teares.
2. a kind of abrasion-resistant cut-off valve according to claim 1, is characterized in that: described protective layer is tungsten carbide coating.
3. a kind of abrasion-resistant cut-off valve according to claim 2, is characterized in that: described tungsten carbide coating is coated on flap and stop valve body contacts face.
