One, technical field:
The utility model relates to the water outlet and the protection checking motion of a kind of low pressure pipe irrigation system.
Two, background technique:
Water outlet be in the low pressure pipe irrigation system from burying the device that fixing tube directly supplies water, pours water to the field conveyance canal underground, according to the sealing principle, water outlet mainly can be divided into two kinds of external force sealing and interior hydraulic pressure sealings.The external force sealing is meant that what application was the most general at present is screw rod gland type by the external force sealing mouth of pipe.Interior hydraulic pressure sealing is the internal water pressure sealing sealing that utilizes pipeline, and pressure is big more, and stagnant water effect is good more, and what application was the most general at present is ball float type (ball valve type).Wherein screw rod gland type is by screw rod roof pressure gland sealing, and the screw mandrel lower end is connected as one by bolt and gland with button watt form by two semi-circular plates, when screw mandrel rotates, drives gland and does upper and lower motion, reaches the effect that discharges water with sealing.Ball float type (ball valve type) is made up of upper bolt and lower bolt two-part, and upper bolt comprises inner thread mouth elbow and depression bar, and lower bolt comprises vertical tube, push pipe, chassis and ball.When irrigating, utilize depression bar that ball is pressed down, water promptly flows out from pipeline; After irrigating end, depression bar is risen, the ball in the vertical tube rises by floating function, and the sealing lower bolt is suitable for reading, stops to supply water.More than two kinds of water outlets are most widely used two kinds of forms in present China low pressure pipe irrigation system, but all have following shortcoming: 1, structure is comparatively complicated, general and fixing tube welding, maintenance is relatively more difficult; 2, current directly flow out from pipeline, and impulse force is big, generally all need build the erosion control pond; 3, switch does not have special tool, and management is difficulty; 4, unprotect facility, it is serious to destroy the damage phenomenon.
Three, model utility content:
The utility model is in order to solve the deficiency in the above-mentioned background technology; the water outlet and the protection checking motion of a kind of low pressure pipe irrigation system are provided; it is simple in structure, energy dissipating erosion control, stagnant water effect are good; open and close flexibly; easy to use, it is little to go out water flow velocity, does not wash away; need not to build the erosion control pond, convenient management.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of low pressure pipe irrigation system goes out water valve and protection checking motion, and its special way is: comprise water outlet, water outlet is located in the protective cap, and water outlet comprises outlet pipe body and sealing mechanism, and sealing mechanism comprises movable gland.
Be provided with the rod member that passes gland and fixedly connected in the above-mentioned outlet pipe body with gland.
Establish crown cap on the above-mentioned gland, the rod member upper end is positioned at the top cap.
Above-mentioned protective cap comprises the concrete pipe, has out head piece on the concrete pipe, and concrete pipe upper end is provided with the concrete cap, has key hole on the concrete cap.
Above-mentioned gland can be the umbrella shape gland.
Above-mentioned rod member can be a screw rod, has nut casing on the screw rod.
Above-mentioned outlet pipe body is connected with fixing tube by flange.
Be provided with rubber pad between above-mentioned umbrella shape gland and the outlet pipe body.
The private key of above-mentioned protective cap comprises vertical rod, and vertical rod one end is a handle, and the vertical rod the other end is a sleeve, and sleeve is provided with bayonet socket.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1. simple in structure, sturdy and durable, utilize flange to be connected with fixing tube, maintenance or replacing are convenient;
2. screw rod adopts the rectangle silk, and nut casing adopts copper spare, opens and closes flexibly long service life;
3. utilize umbrella shape gland and rubber pad sealing, good seal performance, no seepage and no leakage when closing;
4. adopt umbrella shape gland and protective cap combining form to reach the purpose of energy dissipating, it is little to go out water flow velocity, does not wash away, and need not to build the erosion control pond, and protective cap has the effect of protection water outlet again;
5. be furnished with the special use key that discharges water, be convenient to the personal management.
Four, description of drawings:
Fig. 1 is the structural representation of water outlet in the utility model;
Fig. 2 is the structural representation of protective cap in the utility model;
Fig. 3 is the discharge water structural representation of key of protective cap special use in the utility model.
Five, embodiment:
Referring to Fig. 1, water outlet adopts the external force sealing, water sealing structure is by umbrella gland 3, rubber pad 4, screw rod 6, nut casing 5 compositions such as grade, water outlet comprises the outlet pipe body, the outlet pipe body is connected with fixing tube by flange 8, the outlet pipe body is provided with movable umbrella shape gland 3, be provided with rubber pad 4 between umbrella shape gland 3 and the outlet pipe body, be provided with the screw rod 6 that passes gland 3 and fixedly connected in the outlet pipe body with gland, have nut casing 5 on the screw rod 6, screw rod 6 bottoms have pin 7, establish crown cap 2 on the gland 3, screw rod 6 upper ends are positioned at top cap 2, which is provided with bayonet lock 1.
Referring to Fig. 2, protection erosion control facility comprises protective cap, and water outlet is located in the protective cap, and protective cap comprises concrete pipe 11, has out head piece 12 on the concrete pipe 11, and concrete pipe 11 upper ends are provided with concrete cap 10, have key hole 9 on the concrete cap 10, and is furnished with the special use key that discharges water.
