The utility model advantage compared with the prior art: ball-crown body 13 is processed on the top of valve body 1, helps assembling valve rod 21; The bottom of valve body 1 is processed with caulking groove 14, can connects with pipe network very easily; The opening degree of valve 2 can be according to needing control; Water outlet 3 both can one, also can be a pair of, and integrally formed with valve body 1, make terminal with compact integral structure, easy for installation.
Description of drawings
Accompanying drawing is example structure figure of the present utility model.
Embodiment
Please in conjunction with the accompanying drawings, valve body 1 and comprise that the water inlet 3 usefulness plastic processings that are arranged on its sidepiece are shaped, though only provided a water outlet 3 among the figure, and be positioned on the wall body on right side of valve body 1 of location status shown in the figure, yet, be understood that out, if adopt a pair of water outlet 3, another water outlet 3 just is positioned on the wall body on right side of valve body 1 so, and both are at a distance of 180 °, and more particularly two water outlets 3 are a word each other and distribute.The end of each water outlet 3 is processed with and connects screw thread 31, this effect that connects screw thread 31 can be by the connecting screw thread and obtain understanding of the water outlet place on the fire hydrant of having mentioned in seen in the daily life and background technique in front the hurdle, and the leather hose that promptly is used for connecting corresponding specification to peasant household is used for diversion.No matter be a water outlet 3, still two water outlets 3, concrete position should occupy on the valve base 111 in the valve pocket 11.
A ball-crown body 13 has been processed at the top of valve body 1, and central projection is provided with nut seat 131 in the outside of ball-crown body 13, the nut 1311 that build-in and valve rod 4 match in the nut seat 131.For to ball-crown body 13 reinforcement, therefore, be that the inboard of ball-crown body 13 is processed with stiffening rib 12 at the top of the cavity volume 11 of valve body 1, the intensity of ball-crown body 13 is protected.See that by figure valve rod 4 is essentially a screw rod, with nut 1311 mutually spiral shell join, the top of screw rod outside being stretched over valve pocket 11 expanded and to be provided with an attachment cap 41, is extended with hand on the attachment cap 41 and pinches bar 411.Certainly, can make a variation, for example can adopt the form of handwheel to substitute, or adopt the structure of other similar type to replace for the concrete shape and structure of attachment cap 41.The bottom of screw rod is fixed on the valve 2 central formed valve rod matching seats 21 by positioning screwn 211.The bottom of valve 2 that is be fixed with the sealing gasket 22 that material is preferably rubber towards a side of valve base 111.When peasant household be used to hold handle knob bar 411 and along or counterclockwise during turn valve rod 4, just take on the valve 2 and carry or move down by valve rod 4, on move and then open water inlet, when moving down into valve base 111, then close and cut off the water.
The function of the caulking groove 14 of valve body 1 bottom is used for the water pipe 5 of pipe network matched by being self-evident shown in the figure.When connecting,, so be very convenient and efficiently as long as water pipe 5 is inserted in the caulking groove 14.To the processing of caulking groove 14, its length is preferably 5-14cm, is preferably 8-12cm, 10cm more preferably, and the length of caulking groove 14 is just by water pipe 5 compensation, and the width of caulking groove 14 should be as much as possible be complementary with the tube wall of water pipe 5.
The claimant is that example is narrated use of the present utility model with the utility model of the single water outlet 3 of tool.Normally; set up concrete block of wood in the field in farmland; with valve body 1 of the present utility model with protection form ground and double supporting form place in concrete block of wood; the bottom of valve body 1 connects with the field that is laid in and water pipe 5 that correspond to concrete block of wood below, and the end of nut seat 131 and water outlet 3 is exposed to outside concrete block of wood.When agricultural water supply pumping plant supplied water, the underground pipe network system had certain hydraulic pressure, obtained understanding in the relation of arm that can be by the water main in the daily life and every family to this.Peasant household need as long as the turn hand is pinched bar 411, make on the valve rod 4 and move when introduce in the field so, and valve rod 4 upwards moves more, and then the unlatching of valve 2 is big more, and water is drawn from water outlet 3 through valve pocket 11 from water pipe 5.Finish as soon as supply water, so as long as pinch bar 411, until making the sealing gasket 22 on the valve 2 support and on valve base 111, get final product to opposite direction turn hand.
The utility model structure not only is confined to paddy field, also can be suitable for the applications of wheatland, vegetable field or the like and so on.
