Description
Technical field
The utility model relates to a kind of valve, is specially the special discharging valve of a kind of field irrigation, belongs to valve technology field.
Background technique
Agricultural irrigation, mainly refers to the irrigation operation that agricultural tillage district is carried out.Agricultural irrigation mode generally can be divided into for traditional surface irrigation, sprinkling irrigation and slight irrigation etc.
In existing field irrigation development, it is large that pipeline water delivery meets in the time of the head of low pressure 3m left and right water-outlet quantity, and in the time of the head of high pressure 30m left and right, the irrigation conditions of good airproof performance yet there are no similar products.
Model utility content
The purpose of this utility model is in order to provide a kind of field irrigation special discharging valve, to solve the sealing control of field irrigation in the time that high pressure pipe line irrigation discharges water, and in the time that low-pressure pipe irrigation discharges water, keeps water-outlet quantity large and even.
The purpose of this utility model is achieved through the following technical solutions.
The special discharging valve of field irrigation, comprises upper valve body and lower valve body, clamps external sealed cushion rubber, and be bolted between described upper valve body and lower valve body; The inwall of described upper valve body is the up-small and down-big step hole of radius; On the less step sidewall of radius, be provided with some osculums; On the medial axis of described upper valve body, arrange and always put on valve body, and screw rod moving up and down, the internal thread screw interlock that the outer silk screw thread on screw rod mates with the upper end cap center of upper valve body; The upper end of screw rod exceeds the upper end cap of upper valve body, and fixes a handwheel; The lower end of screw rod is that a cross section is the connecting head of T-shape, is socketed a land on described connecting head; The inwall of described lower valve body is the up big and down small step hole of radius; On the medial axis of described step hole step surface, be provided with mounting hole, the longitudinal section of pegging graft in mounting hole is for " T " the water shutoff plate of type; On described water shutoff plate, coated with interior O-ring seal, and be bolted with land; The radius of described connecting head is less than the interior pore radius of interior O-ring seal; Described water shutoff plate radius is less than lower valve body the get out of a predicament or an embarrassing situation internal diameter in hole of hole and upper valve body of topping bar; Be greater than upper valve body the get out of a predicament or an embarrassing situation internal diameter in hole of hole and lower valve body of topping bar.
When moving on to the step surface place of upper valve body on T-shaped water shutoff plate, realize the requirement of sealing under high hydraulic pressure; In the time that T-shaped water shutoff plate moves down between upper and lower valve body, realize and under low hydraulic pressure, realize the object that water-outlet quantity is large.
The lower end of screw rod is that a cross section is the connecting head of T-shape, is socketed a land on connecting head, and land is with " " the water shutoff plate of type is connected with bolt T.Solve the larger frictional force producing due to water stop gel ring while unlatching and caused the difficult problem of opening.
The utlity model has following beneficial effect:
1, when high pressure, rotate handwheel and screw rod is driven on T-shaped water shutoff plate, move on to the small stair hole place of upper valve body, interior O-ring seal seals with step surface; Realize the water shutoff requirement under high hydraulic pressure;
2, when low pressure, T-shaped water shutoff plate is moved down between upper and lower valve body, water from the bottom to top, goes out stream by water shutoff edges of boards hole, realizes in the time of low water head the large and uniform object of water outlet of water-outlet quantity.
3, fitting operation is easy, is difficult for stopping up.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
In figure: 10, upper valve body 11, screw rod 12, handwheel 13, connecting head 14, osculum 15, interior O-ring seal 16, land 20, lower valve body 21, water shutoff plate 30, external sealed cushion rubber.
Embodiment
Further set forth structural feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
As depicted in figs. 1 and 2, the special discharging valve of field irrigation, comprises upper valve body 10 and lower valve body 20, clamps external sealed cushion rubber 30, and be bolted between described upper valve body 10 and lower valve body 20; The inwall of described upper valve body 10 is the up-small and down-big step hole of radius; On the less step sidewall of radius, be provided with some osculums 14; On the medial axis of described upper valve body 10, arrange and always put on valve body 10, and screw rod 11 moving up and down, the internal thread screw interlock that the outer silk screw thread on screw rod 11 mates with the upper end cap center of upper valve body 10; The upper end of screw rod 11 exceeds the upper end cap of upper valve body 10, and fixes a handwheel 12; The lower end of screw rod 11 is a T-shaped connecting head 13, is socketed a land 16 on described connecting head 13; Connecting head 13 radiuses are less than the radius of interior O-ring seal 15 endoporus; The inwall of described lower valve body 20 is the up big and down small step hole of radius; On the medial axis of described step hole step surface, be provided with mounting hole, the longitudinal section of pegging graft in mounting hole is T-shaped water shutoff plate 21; On described water shutoff plate 21, coated with interior water sealing aprons 15, and be bolted with land 16; The radius of described connecting head 13 is less than the interior pore radius of interior O-ring seal; Described water shutoff plate 21 radiuses are less than lower valve body 20 the get out of a predicament or an embarrassing situation internal diameter in hole of hole and upper valve body 10 of topping bar; Be greater than upper valve body 10 the get out of a predicament or an embarrassing situation internal diameter in hole of hole and lower valve body 20 of topping bar.
