Description
Technical field
The utility model relates to valve technology field, is specially a kind of gate valve.
Technical background
At present, the flashboard in gate valve much adopts plate profile structure, the gate valve of this structure, there is the defects such as water resistant hammering blow ability, poor sealing, uses bring impact to gate valve.
Model utility content
The purpose of this utility model is to provide a kind of gate valve, to solve the problem proposed in above-mentioned background technology.
The utility model adopts following technological scheme:
A kind of gate valve, projection rectangular by mouthpiece, screw, valve casing, handle, bayonet socket, screw rod, cavity, internal thread, end cap, valve plate, floor, bottom, annulus forms.
Tube wall and the valve casing of described mouthpiece are connected by screw.
One handle is arranged at described valve casing top, and be provided with a bayonet socket in the middle of handle, bayonet socket is stuck on the screw rod in the middle part of valve casing.
Described screw rod is by the internal thread in the middle of valve casing.
The bottom of described screw rod is provided with end cap, has circular dead slot in end cap, coordinates with the cylindrical step of the bottom of screw rod, when screw rod rotates, end cap can be driven to make upper and lower straight line motion.
There are two holes bottom described end cap, in hole, are separately installed with valve plate.
Be surrounded by annulus bottom described valve plate rectangular, annulus is rectangular relative with the projection on bottom bottom gate valve, and is stuck in the middle of two projections.
Preferably, the outer ring of described screw rod is provided with outside thread, matches with the internal thread in the middle of valve casing.
Preferably, screw thread is provided with in described mouthpiece.
Preferably, a more than floor is provided with in the middle of described two valve plates.
Preferably, rubber layer is provided with in the middle of described two projections.
Compared with prior art, the beneficial effects of the utility model are: this gate valve, easy to use, and water resistant hammer ability is strong, good airproof performance, and long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model partial structurtes schematic diagram.
In figure: 1. mouthpiece, 2. screw, 3. valve casing, 4. handle, 5. bayonet socket, 6. screw rod, 7. cavity, 8. internal thread, 9. end cap, 10. valve plate, 11. floors, 12. bottoms, 13. annulus are rectangular, and 14. is protruding.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of gate valve, is made up of mouthpiece 1, screw 2, valve casing 3, handle 4, bayonet socket 5, screw rod 6, cavity 7, internal thread 8, end cap 9, valve plate 10, floor 11, bottom 12, annulus rectangular 13 and protruding 14 the utility model.
The tube wall of described mouthpiece 1 is connected by screw 2 with valve casing 3, when damaging or when leaking, can being taken apart by valve casing 3, and placing under repair, thus extending the service time of gate valve, reducing user cost by twisting off screw 2 appears in gate valve inside.
One handle 4 is arranged at described valve casing 3 top, and be provided with a bayonet socket 5 in the middle of handle 4, bayonet socket 5 is stuck on the screw rod 6 in the middle part of valve casing 3, can pass through handle with sleeve 4, thus drives screw rod 6 to rotate, and makes screw rod 6 promote and fall, reaches the object of opening and closing gate valve.
Described screw rod 6 is by the internal thread 8 in the middle of valve casing 3, the outer ring of screw rod 6 is provided with outside thread, and match with the internal thread 8 in the middle of valve casing 3, internal thread 8 pairs of screw rods 6 not only serve fixing effect, can also be undertaken promoting and falling by rotating screw bolt 6, reach the object of opening and closing gate valve.
The bottom of described screw rod 6 is provided with end cap 9, has circular dead slot in end cap 9, coordinates with the cylindrical step of the bottom of screw rod 6, when screw rod 6 rotates, end cap 9 can be driven to make upper and lower straight line motion.
Two holes are had bottom described end cap 9, valve plate 10 is separately installed with in hole, valve plate 10 rises along with the rising whereabouts of screw rod 6, thus carry out opening a sluice gate to close lock, a more than floor 11 is provided with in the middle of described two valve plates 10, valve plate 10 is played to the effect of reinforcement, when preventing current excessive, cause valve plate 10 to break.
Annulus rectangular 13 is surrounded by bottom described valve plate 10, annulus rectangular 13 is relative with the projection 14 on the bottom 12 bottom gate valve, and be stuck in the middle of two protruding 14, by rotating screw bolt 6, valve plate 10 being dropped in the middle of two protruding 14 when closing lock, making annulus rectangular 13 be stuck in the middle of two protruding 14, improve the impact capacity of water hammer, be provided with rubber layer in the middle of described two protruding 14, rubber layer has stretchability, can prevent current from flowing through, passing through of current can be limited completely, better tightness.
Be provided with screw thread in described mouthpiece 1, can be connected with pipeline, be convenient to install and use.
