Abstract
The utility model relates to a low pressure valve used for water delivery and irrigation, comprising a three-way joint, a fixed closing end which is arranged on one end of the three-way joint, a valve rod which is arranged along the shaft center of the fixed closing end, and a water stop piston which is matched with the other end of the valve rod. The utility model has the advantages of simple structure, easy installation, good water stop property, and low cost.
Description
The utility model relates to a kind of Low pressure valve, particularly a kind of farmland low-pressure water delivery valve.
At present, the domestic and international low-pressure water delivery engineering irrigation that grows up on a large scale, mainly utilize the water delivery of light PVC hard plastic tube, the Low pressure valve that its water outlet is used has bottle cap type, floating plug formula and screw rod gland type, its structure is made up of reducer pipe and portable piston and reducer pipe and the gland that has a screw rod respectively, has shortcomings such as being difficult for installing, opening and closing inconvenience, sealing are not good, cost height.
The purpose of this utility model is intended to overcome the shortcoming of prior art, proposes a kind of Low pressure valve, have simple in structure, be easy to install, sealing is good, cost is low characteristics.
The utility model comprises a tee union, and an end of tee union disposes a fixed seal head, and the other end that disposes a valve rod, valve rod along the axle center of fixed seal head matches with the sealing piston, can be provided with seal ring between sealing piston and valve pocket.
Can pass through threads engaged between fixed seal head and the valve rod, at this moment, valve rod and sealing piston both can be one and be cast for the unitary whole structure, also can be two parts of one for interconnecting.
During use, as long as rotation valve rod gently, then the sealing piston just can move up and down in valve pocket, thereby finishes the open and close of valve, have simple in structure, be easy to install, sealing is good, cost is low characteristics.
Fig. 1 is one of embodiment of the present utility model.
Fig. 2 is embodiment's of the present utility model two.
Fig. 3 is embodiment's of the present utility model three.
Fig. 4 is the structure principle chart of crank.
Below in conjunction with accompanying drawing, structural principle of the present utility model and working principle are done detailed explanation.
With reference to Fig. 1, the utility model comprises a tee union (7), and an end of tee union (7) disposes a fixed seal head (5), and fixed seal head (5) is fixed by pin (3) with tee union (7) to be one; There is valve rod (18) in the axle center of fixed seal head (5) by screw-thread fit, and the other end of valve rod (18) disposes a sealing piston (8), can be provided with seal ring (9) between sealing piston (8) and valve pocket; For anti-sealing advances valve pocket along the lower end seepage of valve rod (18), valve rod (18) becomes Spielpassung with sealing piston (8), and connection end therebetween is provided with a sealing piece (14), and in addition, among the figure, (11) are aqueducts, and (1) is to open and close pin.
During use, crank (19) (referring to Fig. 4) is enclosed within on the keying pin (1), rotates and open and close pin (1), then sealing piston (8) moves up and down in valve pocket under the drive of valve rod (18) but does not rotate, thereby finishes the open and close of valve.
With reference to Fig. 2, fixed seal head (5) can be provided with bowl watt (12) at the position near valve rod (6), bowl is placed with ball (4) in watt (12), the cooperation that becomes to roll between ball (4) and valve rod (6), and ball (4) is pressed in bowl watt (12) by fixing stand (2); Use screw-thread fit between sealing piston (8) and valve rod (6), a backing pin (10) is fixed in the lower end of valve rod (6).
Open and close pin (1) when going up and rotating when crank (19) (referring to Fig. 4) is enclosed within, then valve rod (6) only rotates and does not move up and down, and sealing piston (8) moves up and down simultaneously, thereby finishes the open and close of valve.
With reference to Fig. 3, fixed seal head can have a cavity on (5), places a spring (16) in the cavity, and an end of spring (16) is fixed a stifled spring piece (17), and the other end disposes a clamp (15); The two ends of valve rod (13) have the bayonet socket that can be meshed with clamp (15).
Crank (19) (referring to Fig. 4) is enclosed within and opens and closes after pin (1) goes up, and rotation valve rod (13) is also upwards carried, and finishes breakdown action when clamp (15) being inserted in the bayonet socket of valve rod (13) lower end; In the time of need closing, along counter-rotation valve rod (13) and depress, clamp (15) is inserted in the bayonet socket of valve rod (13) upper end, and then action is finished.
Claims (8)
