Abstract

A ball valve for agricultural irrigation comprises a valve body with a water supply connector and a cone-shaped pipe. A spherical valve plug, which can make and break current, is arranged in the valve body. A revolving shaft, which is on the valve plug, rotatingly matches with the valve body in a sealed mode. A handle is connected with the revolving shaft. The valve plug is provided with a straight-through hole laterally. Each of two sealing rings, which attaches to the valve plug surface in a sealed mode, is arranged on the valve body corresponding to the water supply connector and a water yield connector respectively. The cone-shaped pipe is at least provided with a check groove which is sleeved with a rubber sealing ring. The cone-shaped pipe is molded in one on the valve body so as to avoid the inconvenience of using a special connector when the traditional agricultural water valve is connected with a flexible pipe. According to the design, the check groove, which increases the resistance when the flexible pipe is pulled out and is sleeved with the sealing ring, is arranged on the cone-shaped pipe, the cone-shaped pipe is sleeved with the orifice of the flexible pipe, the flexible pipe, which is bound with hoops on the check groove of the cone-shaped pipe, is buckled by a common used clamp, the inner wall of the flexible pipe and the sealing ring are sealed. Accordingly, the ball valve for agricultural irrigation matches with the flexible pipe quickly so as to form a good air impermeability, thereby meeting peasant household's requirement of drawing water to irrigate.

Description

A kind of agricultural pouring ball valve

Technical field

The utility model relates to the water pipe junction valve door, particularly makes things convenient for peasant household to irrigate a kind of agricultural pouring ball valve of usefulness.

Background technique

The design of the valve body of present ball core valve is not mostly for agricultural use, if not and the words of agricultural irrigation automatic irrigation, generally all adopt the diversion of soft plastic pipe manually to spray, but connecing flexible pipe, existing valve all needs to add the grafting component, namely install separately one for the joint that is connected with flexible pipe at the water outlet of valve, this joint needs rubber ring, the component assembles such as nut connect to form, cause valve and flexible pipe attended operation convenient not, and also cause poorly sealed leaking because of too much joint additional zero component combination Rig up error easily, therefore the farming ball valve that needs to be resolved hurrily is connected and connects the problem that seals with the rapid and convenient of flexible pipe, to satisfy and to make things convenient for the sprinkling irrigation actual demand of peasant household.

The model utility content

For addressing the above problem, the utility model is intended to propose a kind of agricultural pouring ball valve.

The technological scheme that the utility model addresses the above problem employing is: a kind of agricultural pouring ball valve, contain a valve body with water supply connector and water output connector, but the spherical valve core of break-make current is set in the valve body, the rotating shaft valve seal is rotatably assorted on the spool, one handle is connected with rotating shaft, it is characterized in that: spool laterally is provided with a clear opening, and corresponding water supply connector and water output connector place are embedded with respectively a seal ring of fitting with spool face sealing in the valve body; Water output connector is the conical pipe that can peg graft with flexible rubber hose, is provided with at least a non-return groove on the conical pipe, and non-return groove cover has rubber seal ring.

Described rotating shaft diametric plane is provided with an annular groove, and cover has O type rubber ring in the annular groove, and O type rubber ring top is pressed between valve body and the rotating shaft, and valve core shaft is cooperated with the valve body rotary seal.

Described handle one end axially is connected with the rotating shaft of spool by a screw; The handle that is socketed in the rotating shaft is fixed, by the handle rotational valve core, when the clear opening of spool and water supply connector and water output connector contraposition, spool conducting water supply connector and water output connector through-flow; , when needs were closed, rotatable handle made to rotate and drives the valve core rotation an angle of 90 degrees, and clear opening and water supply connector and water output connector are staggered fully, and spool is blocked the through-flow of water supply connector and water output connector.

Cover has a trim that covers screw on the described handle, and trim is enclosed within and covers hiding screw on the handle, makes the utility model appearance more attractive in appearance.

By will be one-body molded on valve body as the conical pipe of water output connector, exempting Traditional Agricultural also needs the inconvenience of special joint with water valve connecting hose (plastic cement or plastic materials system), and the non-return groove that strengthens the flexible pipe pull-out resistance is set at conical pipe, cover has seal ring in the non-return groove, the direct cover of the flexible pipe mouth of pipe is inserted on the conical pipe, be snapped in flexible pipe with clip commonly used, with the non-return groove place of hose bundle hoop in conical pipe, hose inner wall and seal ring seal, the utility model is connected with the flexible pipe quick-fit and forms good tightness, make things convenient for the needs of peasant household's diversion pouring.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1～ Fig. 4Ball valve is used in shown a kind of agricultural pouring, comprises that one has the valve body 10 of water supply connector 11 and water outlet conical pipe 12, can be provided with a non-return groove 13 with the conical pipe 12 that the flexible pipe mouth of pipe is pegged graft, and non-return groove 13 covers have a rubber seal ring 50; Be embedded with respectively a seal ring 40 of fitting with spool 20 face seals at the corresponding water supply connector 11 of valve body 10 inner chambers and water outlet conical pipe 12 places, spool 20 laterally is provided with a clear opening 21, a rotating shaft 22 is fixed at spool 20 tops, annular groove 23 covers in the rotating shaft 22 have an O type rubber ring 60, spool 20 is inserted in the valve body 10, seal ring 40 in spool 20 surperficial valve body 10 inner chambers is fitted, O type rubber ring 60 tops are pressed between valve body 10 and the rotating shaft 22, the rotating shaft 21 at spool 20 tops cooperates by O type rubber ring 60 sealed rotational with valve body 10, one handle 30 1 ends and rotating shaft 22 sockets, one screw, 70 handles 30 axially are connected and fixed with rotating shaft 22, then trim 80 is placed in to cover on the handle 30 and hides screw 70, so far write as assembling of the present utility model.
