It is marked in figure: handle 1, valve body 2, nut 3, plus screw 4, bulb 5, spool 6, nylon washer 7.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
Such as attached drawing 1, shown in attached drawing 2, a kind of ball valve, it is characterised in that: including valve body 2, nylon washer 7, bulb 5,
Plus screw 4, handle 1, spool 6, nut 3, sealing ring.The valve body 2 successively includes the first valve body, the second valve from front to back
Body, third valve body；First valve body, the second valve body, third valve body are cylinder, and internal hollow out；The diameter of first valve body
Less than the second valve body, the second valve diameter is less than third valve body.Valve body 2 uses stair-stepping design, the first valve body and third valve
Body diameter is different, adapts to different line sizes, the second valve body plays transitional function, while providing movable sky for other component
Between.First valve body is provided with external screw thread, and third valve body is provided with internal screw thread, convenient for being connected with pipeline.Valve body 2 further includes connecting cylinder,
Connecting cylinder is vertically arranged in 2 top of valve body, and inside is provided with circular through hole, and it is convex that a rectangle is each side arranged in connecting cylinder
Block, connecting cylinder is for the connection with handle 1.
The whole handle 1 is in concave shape, including two handles, an interconnecting piece, handle turn convenient for user.Handle
For inequilateral hexagon, top protuberance is separately positioned on interconnecting piece two sides, and such design is convenient for users to the application of handle 1
Power.Interconnecting piece top is taper, and center is provided with screw hole, and plus screw 4 passes through screw hole, is threadedly secured under handle 1
6 top of spool in portion.Interconnecting piece lower part is cylinder, and internal hollow out, hollow part is circle, and size and connecting cylinder are adapted,
Interconnecting piece encases connecting cylinder.Interconnecting piece left and right side is respectively provided with a groove, groove center point and connecting cylinder rectangular cam
In the same plane, when user's rotating handle 1 counterclockwise, interconnecting piece be can rotate, when turning to certain angle, groove
Left end can block connecting cylinder rectangular cam, reach the 1 attainable limit of institute of handle at this time；After this, user is clockwise
Rotating handle 1, interconnecting piece continues to rotate, until the right end of groove blocks connecting cylinder rectangular cam.Groove and rectangular cam
Design, can guarantee will not rotate excessive phenomenon when user's rotating handle 1, guarantee the leakproofness of valve.
There are two include the first nylon washer 7, the second nylon washer 7 for the nylon washer 7.Nylon washer 7 is circular ring shape,
Setting guarantees the leakproofness inside valve body 2 in 2 inside hollow part of the second valve body.The bulb 5 is sphere, and center is provided with circle
The through-hole in section；5 top of bulb is provided with groove.The effect of spool 6 is partition or unlatching airflow channel.The spool 6 is solid
It is scheduled on 5 top of bulb, spool 6 includes connecting plate, sealing ring mounting portion, screw connection portion.Connecting plate is semicircular plate, with valve head
The groove size on top is adapted, and the two cooperation guarantees that torque can be passed to bulb 5 when handle 1 rotates, and enables bulb 5
Quick rotation.Sealing ring mounting portion is cylinder, and sealing ring mounting groove is arranged；Screw connection portion is cylinder, and top is provided with spiral shell
Nail hole；Described 4 one end of plus screw is fixed in screw connection portion, and the other end is in contact with 1 hollow part inner wall of handle.Cross spiral shell
Nail 4 makes 1 electrical connection of spool 6 and handle, is readily disassembled simultaneously, is conveniently replaceable maintenance.
Preferably, the hollow part inside valve body 2 is arranged in bulb 5, front end is in contact with the first nylon washer 7, after
End is contacted with the second nylon washer 7, and bulb 5 can make the rotation of certain angle between two nylon washers.The nut 3
It is connect by screw thread with valve body 2, such mode is easy to disassemble and safeguards.Cylindrical hole is provided with inside nut 3；Second nylon
Washer 7 is arranged in 3 front end of nut；There are two the sealing rings, is mounted on the sealing ring mounting portion of spool 6.Sealing ring guarantees
Sealing performance.
In use, valve body is passed through in combustion gas, nylon washer, bulb, the isostructural middle through-hole of nut, what combustion gas was passed through leads to
Road is known as airflow channel.Operator turns handle, and handle drives Spool rotating, and spool drives bulb to rotate by connecting plate, when
When handle is vertical with the direction of valve body, airflow channel is fully opened, fuel gas transmission to gas-cooker；When the axis side of handle and valve body
To it is parallel when, the airflow channel of spool completely closes.Since bulb is easy to rotate, the circulation area of airflow channel is far smaller than ball
The sectional area of head, therefore handle need to only move a part of angle and just bulb can be made to open or close airflow channel, it is described previously
Handle it is parallel or vertical with valve axis direction when reach airflow channel opening and closing effect, be merely to illustrate the course of work.Operation
Person can judge whether to close airflow channel according to the rotation angle of handle, and operation is simple and reliable.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications
Also it should be regarded as in scope of protection of the utility model.
