Abstract
The utility model provides a pressure regulator for the water saving irrigation, which is composed of a housing, an inlet stopper, a sealing ring, a pressure regulating element, a spring, a rubber film, a press cap and an outlet stopper, wherein, the inlet stopper and the sealing ring are positioned at the upriver part of the housing, and other elements are positioned at the downriver part of the housing. The utility model has the advantages that the downriver pressure basically keeps unchanged when the upriver pressure has great changes, and the uniformity degree of water irrigation can be enhanced. The inlet point of a branch pipe or a capillary pipe for a micro-irrigation or a spray-irrigation system can also be directly arranged on the upriver part of a spray head, and can also be used for the water supply systems of high-rise buildings or mountain cities.
Description
The utility model relates to a kind of pressure-regulating device, especially relates to a kind of irrigation pressure regulator.
In the irrigation system, when upstream extremity pressure changed, downstream pressure also can change thereupon, and it is disconnected or inhomogeneous to cause downstream water supply to stop.External like product make up by 13 elements, and component number is more, and shell is designed to the form of bevel arm piece, manufacture difficulty is strengthened, the cost raising.
The purpose of this utility model is to fill the domestic gaps, provide a kind of water-saving irrigation pressure regulator.This device can be used for arm or the hollow billet import department in the various water-saving irrigation systems, also can be directly installed on the shower nozzle upstream, when upstream pressure changes, the inlet pressure of arm, hollow billet or shower nozzle is not influenced by it, keep constant, thereby can improve uniformity of irrigation water appilcation, improve the availability of irrigation water, reach the purpose of water saving.
The technical solution of the utility model is such:
A kind of water-saving irrigation pressure regulator comprises: shell, import plug, sealing ring, voltage regulation component, spring, rubber membrane, gland and outlet plug; The two ends, upstream and downstream of described shell are the thin-walled tubular structure, and the middle part is provided with a partition wall, which is provided with a through hole that can pass and can therefrom move for the upstream extremity of voltage regulation component, and its downstream outer wall is provided with a port; Described voltage regulation component is a T type structure, and the sectional area size of upstream extremity and downstream differs certain proportion, and the centre is provided with through hole; Described spring is arranged on the upstream extremity of voltage regulation component, between the downstream and partition wall of shell; Described import plug is provided with the hole that can pass for the upstream extremity of voltage regulation component, and the periphery of import plug is provided with the inlet opening; Described sealing ring is arranged between import plug and the partition wall; Described rubber membrane is arranged between the downstream and gland and outlet plug of voltage regulation component; The downstream of described outlet plug and shell is fastening; Described gland and voltage regulation component downstream are fastening.
The operation principle of this device is: when voltage regulation component upstream extremity water pressure increases, its downstream pressure also can increase thereupon, but because the area of voltage regulation component downstream is much larger than the area of upstream extremity, so downstream gross pressure value added is greater than upstream extremity gross pressure value added, the roam all around the would that makes progress of the official post voltage regulation component of this gross pressure is passed, compress spring simultaneously, the gap of voltage regulation component and import plug is reduced, the loss of flood peak increases.Vice versa.Thereby guarantee that when the pressure regulator upstream pressure had bigger variation, downstream pressure remained unchanged substantially.
Water-saving irrigation of the present utility model is compared with existing product with pressure regulator, has following outstanding advantage:
When 1, the upstream pressure of this device had bigger variation, downstream pressure remained unchanged substantially, plays the pressure regulation effect, thereby improved uniformity of irrigation water appilcation, improved the availability of water, saved the water source.
2, of many uses, can be used for the arm or the hollow billet import department of slight irrigation or sprinkling irrigation system, also can be directly installed on the shower nozzle party upstream, the influence that makes the inlet pressure of arm, hollow billet or the shower nozzle of system not changed by its upstream pressure.This device also can be used for the water system in skyscraper or mountain city, is supplied water in the upper strata and is not subjected to the influence of lower layer with water.
3, sealing ring is a consumable accessory, takes off the import plug, and is just replaceable, the convenient use.
4, structural design advantages of simple is made easily, and cost reduces.
Below in conjunction with drawings and Examples, further describe the utility model.
Fig. 1 is the cutaway view of water-saving irrigation with pressure regulator;
Fig. 2 is the left view of a kind of import plug among Fig. 1;
Fig. 3 is the left view of another kind of import plug among Fig. 1;
Fig. 4 is the schematic diagram of external a kind of pressure regulator.
With reference to Fig. 4, external like product element number is many, form by 13 elements, peace be oblique T type pipe 1 ', nut 2 ', packing ring 3 ', go up voltage regulation component 4 ', down voltage regulation component 5 ', rubber membrane 6 ', packing ring 7 ', packing ring 8 ', nut 9 ', spring 10 ', latch bracket 11 ', enclosing cover 12 ' and plug 13 ', because tiltedly T type pipe 1 ' difficult making, so the manufacturing cost height, difficulty is big.
Fig. 1 illustrates the structure of water-saving irrigation of the present utility model with pressure regulator.With reference to Fig. 1, this pressure regulator is made up of 8 elements, and they are shell 1, import plug 2, sealing ring 3, voltage regulation component 4, spring 5, gland 6, rubber membrane 7 and outlet plug 8.Two ends, shell 1 upstream and downstream 11,12 are the thin-walled tubular structure, and the middle part is provided with a partition wall 13, and partition wall 13 is provided with a through hole 14, and the upstream extremity 41 of voltage regulation component 4 passes from through hole 14 and be removable, and the outer wall of downstream 12 is provided with a port 15; Voltage regulation component 4 is a T type structure, and the sectional area size of upstream extremity 41 and downstream 42 differs certain proportion, and the centre is provided with a through hole 43; Spring 5 is arranged on the upstream extremity 41 of voltage regulation component 4, between the downstream 12 and partition wall 13 of shell; Import plug 2 is provided with a hole 21, and the upstream extremity 41 of voltage regulation component 4 passes this hole 21, and import plug periphery is provided with inlet opening 22; Sealing ring 9 is arranged between import plug 2 and the partition wall 13; Rubber membrane 7 is provided with projection 71, is arranged between the downstream 42 and gland 6 and outlet plug 8 of voltage regulation component 4; Outlet plug 8 is fastening with downstream 12 inwalls of shell 1, and gland 6 is fastening with voltage regulation component 4 downstream 42.
Inlet opening 22 on the import plug 2 can evenly distribute, and can be the X type and distribute, and as shown in Figure 2, also can be the Y type and distribute as shown in Figure 3.
Gland 6 can or be threaded with the riveted joint welding with the end face of the downstream 42 of voltage regulation component 4, and the big distolateral wall 81 of outlet plug 8 also can fix wherein rubber membrane 7 with riveting, weld or being threaded with the port inner wall of the downstream 12 of shell 1.
