Abstract

The utility model discloses an anti-seep pipe water outlet of farmland, which comprises a lower vertical pipe which is connected with a delivery pipeline, an upper cover pipe with a water outlet and a cutoff valve for controlling water current to pass through, wherein the lower vertical pipe is provided with an integral connecting flange, the upper cover pipe and a flange disc are split structures, which can relatively rotate freely, the contact surface between the lower vertical pipe and a valve core is a conical surface, the connector between the outer periphery of the lower vertical pipe and the upper cover pipe is provided with a groove, a seal ring is arranged in the groove, the periphery on the valve core, which is contacted with the conical surface of the lower vertical pipe, is provided with a groove, a seal ring is arranged in the groove, and all the seal rings are 'Y'-shaped seal rings. The anti-seep pipe water outlet of farmland reinforces the hermeticity through adopting the 'Y'-shaped seal rings and arranging rubber seal nuts on the connector of the upper cover pipe and a valve rod, does not have the water-leakage phenomenon, and the upper cover pipe and the lower vertical pipe can be relatively rotated, thereby adjusting the angle of the water outlet at random, and the anti-seep pipe water outlet of farmland can be conveniently connected with delivery pipes such as outside sprayers, drip irrigators and the like, and the use and operation are more convenient.

Description

Farmland antiseepage pipe water outlet

Technical field

The utility model relates to the pipeline water outlet in a kind of farmland water-saving irrigating facility, particularly a kind of farmland antiseepage pipe water outlet.

Background technique

At present, in water-saving irrigation, the pipeline outlet valve is the important composition parts, the general field irrigation water transfer pipe network water outlet of Shi Yonging generally adopts the Sealing of " o " shape or taper, and this Sealing weares and teares when using easily, sealing effect is bad, easily produces water leakage phenomenon.Usually, the outlet valve that people use generally all is fixing locked, water outlet all can not rotate freely angle, can not be connected with conduit pipes such as outside sprinkling irrigation, drip irrigations easily, inconvenient operation during use, and the conversion of the multiple joint of needs when being connected with the outside, the water outlet direction can not be adjusted, and causes and uses operation inconvenience.

The model utility content

The utility model technical issues that need to address provide a kind of water outlet direction and can freely adjust, and seal tight watertight farmland antiseepage pipe water outlet.

For addressing the above problem, technical solution adopted in the utility model is: a kind of farmland antiseepage pipe water outlet, comprise the lower standing tube that is connected with water transport pipeline, last vestlet with water outlet, the stop valve that controlled water flow is crossed, last vestlet is connected by flange with lower standing tube, described stop valve is made up of spool and valve rod, spool is connected stem lower portion, and valve rod and last vestlet are for being threaded, and lower standing tube has the adpting flange of one, last vestlet and flange plate are for dividing body structure, can rotate relatively freely, the surface of contact of lower standing tube and spool is a conical surface, is provided with groove with last vestlet joint on the lower standing tube outer peripheral surface, be equipped with seal ring in the groove, be provided with groove on the circumferential surface of the upper and lower standpipe conical surface contact of spool, be equipped with seal ring in the groove, the above seal ring all is " Y " RunddichtringO.

Further improve and be: valve rod and last vestlet joint at last vestlet are provided with the rubber seal nut.

Further improve and be: be provided with attachment hole in the middle of the spool, be fixed on the valve rod, be provided with groove, be equipped with " Y " RunddichtringO in the groove at spool upper valve core and valve rod joint by attachment hole.

Adopt the beneficial effect that technique scheme produced to be: this is novel by adopting " Y " RunddichtringO, and the rubber seal nut is set in the joint of last vestlet and valve rod, strengthened sealing, do not have water leakage phenomenon, last vestlet is connected with lower standing tube by flange, last vestlet and flange split, can rotate relatively freely, thereby can adjust the angle at the mouth of a river arbitrarily, can be connected with conduit pipes such as outside sprinkling irrigation, drip irrigations easily, use more convenient to operate.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model upper outlet body, stop valve structure schematic representation;

Fig. 3 is the utility model lower standing tube structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As Fig. 1,2, shown in 3, this novel lower standing tube 6 that comprises, stop valve and last vestlet 3, wherein going up vestlet 3 and lower standing tube 6 is connected by flange, lower standing tube 6 and flange are structure as a whole, on lower standing tube 6 outer peripheral surfaces, be provided with groove with last vestlet 3 joints, be provided with " Y " RunddichtringO 9 in the groove, have the bolt hole on the flange, has water outlet 8 on the last vestlet 3, last vestlet 3 and flange plate 5 are for dividing body structure, flange plate 5 and last vestlet 3 can relatively rotate, have on the flange with lower standing tube on the corresponding hole of flange bolt fixed hole, connect upward vestlet 3 and lower standing tube 6 by bolt, after the connection, be connected for the microgap between last vestlet 3 and lower standing tube 6 and the flange, stop valve comprises spool 4 and valve rod 1, wherein valve rod 1 and last vestlet 3 are connected by worm structure, joint at last vestlet 3 is provided with groove, be provided with rubber seal nut 2 in the groove, the center is provided with the hole that is connected with valve rod 1 on the spool 4, spool 4 is fixed on the bottom of valve rod 1 by attachment hole, (joint) has groove on the inwall in spool 4 holes, be equipped with " Y " RunddichtringO 7 in the groove, end in contact is sealed water on spool 4 and lower standing tube 6 inwalls, and it can not be flowed out, and the face that contacts with spool in lower standing tube inwall upper end is a conical surface, the spool excircle is provided with groove, is equipped with " Y " RunddichtringO 10 in the groove.

Using method:

During use, by in valve stem tip drive plate being installed, actuate valve stem is rotated, and valve rod drives spool and moves up and down, thereby realizes opening and closing, and makes the water break-make, in the time of need adjusting mouth of a river angle, as long as pull vestlet to suitable angle.
