Abstract
The utility model relates to a push-and-pull valve, belonging to the field of valves. The utility model is mainly composed of a valve main body, a press plate, a push-and-pull rod, a cover plate, a water inlet, a water outlet, a hexagonal nut, and a push-and-pull handle. The utility model is characterized in that an f-shaped structure is adopted by the hollow cavity of the valve main body, one end of the push-and-pull rod is provided with the press plate, the part corresponding to the bearing part of the valve main body is provided with an O-shaped sealing ring, the push-and-pull rod is also provided with a pin, and the pin is matched with the key groove of the bearing part of the valve main body. The utility model has the advantages of novel and simple structure, low cost, good tightness, and high durability. Abrasion is reduced because a push-and-pull structure is used.
Description
The utility model relates to a kind of Push-and-pull valve, belongs to the valve field.
Now, valve of a great variety all adopts left rotation and right rotation to reach the Push And Release of valve mostly, between the inner member of valve friction takes place and produces the gap and leak thereby make, the generation gap such as the seal ring at the ball that resembles ball valve and two ends frequently rotates friction and leaking; And for example the flat position on groove on the sphere and the driving lever frequently moves back and forth, and makes both become the variation of inside and outside circle shape, not only leaks, and loses function and can not use.
Task of the present utility model provides a kind of Push-and-pull valve, adopts to push away and draw the valve Push And Release, and it can overcome between the valve inner member weares and teares, and reaches to avoid the purpose of leaking.
The utility model is realized by following technical solution.
Push-and-pull valve comprises valve body, pressing plate, pull bar, cover plate, water intake, water outlet, and hexagon nut, its structural feature of push-pull handle are: valve body cavity is
That end that structure, pull bar are in the cavity is provided with the pressing plate that the periphery studs with the rubber oil sea circle, and the pull bar that is in the valve body bearing part is provided with the O RunddichtringO, is provided with pin and matches with the keyway that the valve body bearing part is provided with on pull bar; Be located at the pressing plate that pull bar is in the end in the cavity and cooperate, be provided with the rubber oil sea circle between pressing plate and the cone with a cone; The cover plate that cooperates with valve body is provided with the O RunddichtringO; The hexagon nut that cooperates with the valve body water intake is provided with O RunddichtringO and rubber oil sea circle.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the utility model structural representation.
As shown in the figure, Push-and-pull valve is made up of valve body 13, pressing plate 9, pull bar 11, cover plate 1, water intake 2, water outlet 17, hexagon nut 4, push-pull handle 15, and its structural feature is: valve body 13 cavity structures are
Shape, that end that pull bar 11 is in the cavity is provided with the pressing plate 9 that the periphery studs with rubber oil sea circle 8, the pull bar that is in the valve body bearing part is provided with O RunddichtringO 12, is provided with pin 14 on pull bar 11, matches with the keyway 16 that the valve body bearing part is provided with; In order to reduce the resistance of water, be provided with a cone 6 at pressing plate 9 places and cooperate, be provided with rubber oil sea circle 7 between pressing plate 9 and the cone 6; In order to make good seal performance, again with cover plate that valve body 13 cooperates on be provided with O RunddichtringO 3; The hexagon nut 4 that cooperates with the water intake 2 of valve body 13 is provided with O RunddichtringO 5 and rubber thigh oil seal washer 10.
Push-and-pull valve shown in the accompanying drawing 1 is to be in closed condition, in the time will opening, push-pull handle is down pressed, and it is fixing to be in the rotation of groove 13 places at pin 14, and cone 6 overcomes the resistance of water in down by process, and pressing plate 9 leaves in the valve body cavity
The shape structure, water or fluid flow to cavity from water intake under the effect of pressure, cross
The shape structure flows out from water outlet 17, in the time will closing, 15 groups of push-pull handles are risen, pressing plate 9 with
Structure forms sealing, cuts off the water route, reaches and closes purpose.
From as can be known above-mentioned, the utlity model has simple in structure, reasonable in design, low cost and other advantages.Owing to adopt push-pull configuration, reduced wearing and tearing thereby durable in use, also adopted the sealing of O RunddichtringO and rubber oil sea circle simultaneously, have excellent sealing performance.
