Abstract
The utility model discloses the special discharging valve of a kind of farmland low pressure irrigation, comprise the lower valve body of upper valve body and hollow tubular, be bolted between upper valve body and lower valve body; Upper valve body sidewall is provided with some osculums; The medial axis of described upper valve body is arranged and always puts on valve body and screw rod moving up and down; 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 a T-shaped connecting head, connecting head is socketed a land; Described land installs a water shutoff disk by screw; The oral area of described lower valve body is provided with a circle water sealing aprons, and the diameter of described water shutoff disk is less than the internal diameter of upper valve body, is greater than the diameter of bore of water sealing aprons and is less than the external diameter of water sealing aprons; The bottom of lower valve body is communicated with offlet.When discharging water, water shutoff disk moves, from the bottom to top, by the water outlet of upper valve body osculum, when can realize low pressure, water-outlet quantity is large and water outlet is even for water; During water shutoff, water shutoff disk moves down with water sealing aprons airtight.
Description
Technical field
The utility model relates to a kind of valve, is specially the special discharging valve of a kind of farmland low pressure irrigation, belongs to valve technology field.
Background technique
Agricultural irrigation, mainly refers to the irrigation operation carried out agricultural tillage district.Agricultural irrigation mode generally can be divided into for traditional surface irrigation, sprinkling irrigation and slight irrigation etc.
There is following defect in existing farmland low pressure irrigation:
When 1, adopting the cloudy well of concrete to discharge water, utilization be plank dash, sealing is poor.
When 2, separately having the similar ball valve and butterfly valve control operation of employing, because farmland irrigating water's impurity is more, easily block, and operation effort,
Model utility content
The purpose of this utility model is to provide one to be applicable to the special discharging valve of farmland low pressure irrigation, keeps water-outlet quantity large and uniform object to solve when the water shutoff of farmland when pouring water with pipeline controls and discharge water.
The purpose of this utility model is achieved through the following technical solutions.
The special discharging valve of a kind of farmland low pressure irrigation, comprises the lower valve body of upper valve body and hollow tubular, is bolted between upper valve body and lower valve body; Upper valve body sidewall is provided with some osculums; The medial axis of described upper valve body is arranged and always puts on valve body and screw rod moving up and down; 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 a T-shaped connecting head, connecting head is socketed a land; Described land installs a water shutoff disk by screw; The oral area of described lower valve body is provided with a circle water sealing aprons, and the diameter of described water shutoff disk is less than the internal diameter of upper valve body and the external diameter of water sealing aprons, is greater than the diameter of bore of water sealing aprons; The bottom of lower valve body is communicated with offlet.
The described screw rod upper end portion side of being tenon, fixes with the square hole at handwheel center, provides enough torsion.
During water shutoff, rotating screw bolt, drives water shutoff disk to be displaced downwardly to the water sealing aprons of lower valve body oral area.
The utility model has following beneficial effect:
1, during water shutoff, water shutoff disk is displaced downwardly to lower valve body oral area, airtight with water sealing aprons, thus plays the effect of water shutoff; During low pressure, water shutoff disk moves, leaves with water sealing aprons; Water from the bottom to top, obtain jumbo water outlet, and water outlet is even by dewatering orifice;
3, fitting operation is easy, not easily blocks.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model;
In figure: 1, upper valve body 2, lower valve body 3, screw rod 4, handwheel 5, connecting head 6, land 7, water shutoff disk 8, water sealing aprons 9, osculum.
Embodiment
Structural feature of the present utility model is set forth further below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the special discharging valve of a kind of farmland low pressure irrigation, comprises the lower valve body 2 of upper valve body 1 and hollow tubular, is bolted between upper valve body 1 and lower valve body 2; Upper valve body 1 sidewall is provided with some osculums 9; The medial axis of described upper valve body 1 is arranged and always puts on valve body 1 and screw rod moving up and down 3; The upper end of screw rod 3 exceeds the upper end cap of upper valve body 1, and fixes a handwheel 4; The lower end of screw rod 3 is a T-shape connecting head 5, connecting head 5 is socketed a land 6; Described land 6 installs a water shutoff disk 7 by screw; The oral area of described lower valve body 2 is provided with a circle water sealing aprons 8, and the diameter of described water shutoff disk 8 is less than the internal diameter of upper valve body 1, is greater than the diameter of bore of water sealing aprons 8 and is less than the external diameter of water sealing aprons 8; The bottom of lower valve body 2 is communicated with offlet.
The described screw rod 3 upper end portion side of being tenon, fixes with the square hole at handwheel 4 center, provides enough torsion.
During water shutoff, rotating screw bolt 4, drives water shutoff disk 7 to be displaced downwardly to lower valve body 2 oral area, and airtight with water sealing aprons 8, plays the object of water shutoff.
When low pressure uses, rotating screw bolt 4 makes water shutoff disk 7 moves, and leaves with water sealing aprons 8, and water from the bottom to top, by water shutoff disk 7 and osculum 9, can obtain jumbo water outlet, and water outlet is even.
