A kind of farmland irrigation water outlet
Technical field
The utility model relates to field irrigation field, is a kind of farmland irrigation water outlet specifically.
Background technique
Irrigation water outlet is the conventional pipe line parts of field of agricultural irrigation, existing irrigation water outlet drives moving up and down of waterstop to control the switching of irrigation water outlet and the size of water flow by leading screw, but under the closed condition of irrigation water outlet, water is because the effect of hydraulic pressure is run out of from the gap between waterstop and leading screw, in addition because the leading screw of existing irrigation water outlet reaches outside outlet pipe, in the course of the work, water is often run out of from the gap between outlet pipe and leading screw, affect the normal work of irrigation water outlet, also caused the waste of water resources.
In the time that farmland adopts the mode of droplet or sprinkling irrigation to irrigate, just need to install reducing section header connecting soft band additional at the outlet position of irrigation water outlet, existing outlet position adopts screw thread interception, in being connected with reducing section header, because causing soft bag, rotation twists into twisted shape, need to further adjust inconvenience very.
Model utility content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of farmland irrigation water outlet, and the design of its sealing mechanism is more reasonable, good sealing effect, long service life, and can be connected with reducing section header fast and easily.
In order to address the above problem, the utility model is by the following technical solutions: a kind of farmland irrigation water outlet, comprise intake pipe, outlet pipe, leading screw, knob, it is characterized in that, described intake pipe is connected by flange plate with outlet pipe, flange plate joint is provided with flange rubber cushion, described leading screw is located at the inner chamber of outlet pipe, leading screw is provided with the waterstop matching with leading screw, the inwall of outlet pipe is provided with slide rail, slide rail matches with the rail slot on waterstop, the connecting rod of the lower end of knob is connected with the upper end portion of the leading screw in outlet pipe through outlet pipe, the joint of connecting rod and outlet pipe inwall is provided with seal ring, connecting rod is provided with draw-in groove, in draw-in groove, be provided with jump ring, the below of the underpart of described leading screw is provided with lower seal, leading screw regulates waterstop to move down, the outer ring of waterstop and flange rubber cushion compress and form sealing, now the inner ring of waterstop and lower seal compress and form sealing.
Further: the water outlet position of outlet pipe is provided with buckle quick-acting joint.
Further: described intake pipe and the material of outlet pipe are glass steel material.
Further: the material of described flange rubber cushion is polyurethane material.
The beneficial effects of the utility model are:
1, design of Sealing Structure is more reasonable, good sealing effect.
2, the water outlet position of outlet pipe is provided with buckle quick-acting joint, in the time that farmland adopts the mode of droplet or sprinkling irrigation to irrigate, can conveniently install reducing section header connecting soft band additional.
3, the material of described intake pipe and outlet pipe is glass steel material, overcome the easily aging and large shortcoming of the not corrosion-resistant weight of metal material of plastic material, the material of described flange rubber cushion is polyurethane material, overcome the problem of aging of traditional quality of rubber materials, improved working life of the present utility model.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
In figure: 1 knob, seal ring on 2,3 leading screws, 4 waterstops, 5 slide rails, 6 outlet pipes, 7 buckle quick-acting joints, 8 flange rubber cushions, 9 flange plate, 10 lower seal, 11 intake pipes, 12 connecting rods, 13 jump rings.
Embodiment
As shown in Figure 1, a kind of farmland irrigation water outlet, comprise intake pipe 11, outlet pipe 6, leading screw 3, knob 1, described intake pipe 11 is connected by flange plate 9 with outlet pipe 6, flange plate 9 joints are provided with flange rubber cushion 8, described leading screw 3 is located at the inner chamber of outlet pipe 6, leading screw 3 is provided with the waterstop 4 matching with leading screw 3, the inwall of outlet pipe 6 is provided with slide rail 5, slide rail 5 matches with the rail slot on waterstop 4, the connecting rod 12 of the lower end of knob 1 is connected with the upper end portion of the leading screw 3 in outlet pipe 6 through outlet pipe 6, connecting rod 12 is provided with seal ring 2 with the joint of outlet pipe 6 inwalls, connecting rod 12 is provided with draw-in groove, in draw-in groove, be provided with jump ring 13, jump ring 13 can effectively limit leading screw 3 and be positioned at the position of outlet pipe 6, ensure that leading screw 3 can only can not move up and down in the interior rotation of outlet pipe 6.The below of the underpart of leading screw 3 is provided with lower seal 10, and leading screw 3 regulates waterstop 4 to move down, and the outer ring of waterstop 4 and flange rubber cushion 8 compress and form sealing, and now the inner ring of waterstop 4 and lower seal 10 compress and form sealing.Efficiently solve water from the problem that gap is run out of and water is run out of from the gap between outlet pipe and leading screw between waterstop 4 and leading screw 3, good sealing effect.
The water outlet position of outlet pipe 6 is provided with buckle quick-acting joint 7, in the time that farmland adopts the mode of droplet or sprinkling irrigation to irrigate, can conveniently install reducing section header connecting soft band additional.Described intake pipe 11 and the material of outlet pipe 6 are glass steel material, overcome the easily aging and large shortcoming of the not corrosion-resistant weight of metal material of plastic material, the material of described flange rubber cushion 8 is polyurethane material, overcome the problem of aging of traditional quality of rubber materials, improved working life of the present utility model.
The utility model is not limited only to above-described embodiment.
