In the above manner, the water-saving irrigation valve can effectively prevent the phenomenon of water leakage, save the water and protect the environment.
Description
Technical field
The utility model relates to agriculture field irrigation facility field, particularly relates to a kind of water-saving irrigation valve.
Background technique
Along with advocating of economizing type thought, agricultural water-saving irrigation consciousness is more and more accepted and is paid attention to by wide farmers.Therefore in farmland irrigating engineering, the thin dew of the crops of paddy rice and so on irrigated just relates to problem of water saving, so-called thin reveal to irrigate be meant and irritate thin water, light irrigation, Chang Lutian.Thereby quietly be seen in water-saving irrigation valve just as the fire hydrant apperance in the field, nationality by this type water-saving valve realize to the field piece according to cutting off the water supply or waterproof.
Existing water-saving irrigation valve mainly adopts cast iron to make, and is undesirable because of the perishable durability of usefulness that causes, and connects inconvenience with underground pipe network.The seal spool property of existing water-saving irrigation valve is poor, leaks at the switch place easily.
The model utility content
The technical problem that the utility model mainly solves provides a kind of water-saving irrigation valve, can effectively prevent to leak.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of water-saving irrigation valve is provided; The spool, the end that comprise valve body, be installed in the valve cavity are connected the valve rod that also can drive spool and move up and down, the water inlet interface that is connected with water pipe with spool; And the water outlet interface, the one side that said spool is connected with valve rod is fixed with the imbibition body.
In preferred embodiment of the utility model, the length after the said imbibition body suction is more than or equal to the diameter of water outlet interface.
In preferred embodiment of the utility model, said valve body is the structure that PVC processes.
In preferred embodiment of the utility model, said water inlet interface exterior edge face comprises a circle U-shaped caulking groove, and said caulking groove width is identical with said water pipe wall thickness.
In preferred embodiment of the utility model, the degree of depth of said caulking groove is more than or equal to 5mm.
In preferred embodiment of the utility model, said water-saving irrigation valve also comprises handle, and said handle is connected with the other end of valve rod.
In preferred embodiment of the utility model, said water outlet interface internal surface has worm structure.
The beneficial effect of the utility model is: the water-saving irrigation valve of the utility model can effectively prevent water leakage phenomenon, water-saving and environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model water-saving irrigation valve one preferred embodiment;
The mark of each parts is following in the accompanying drawing: 1 is valve body, and 11 is cavity, and 12 is mounting hole, and 2 is spool, and 3 is valve rod, and 4 are the water inlet interface, and 41 is caulking groove, and 5 are the water outlet interface, and 6 is expander, and 7 is handle, and 8 is water pipe.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model is embodiment comprise:
A kind of water-saving irrigation valve comprises: valve body 1, spool 2, valve rod 3, water inlet interface 4, water outlet interface 5, expander 6 and handle 7.
The cavity 11 that supplies spool 2 to install is arranged in the valve body 1, and valve body 1 is " ├ " shape, and wherein there is mounting hole 12 valve body 1 upper end, and valve rod 3 passes mounting hole 12 1 ends entering cavity 11 and is connected with spool 2, and the other end of valve rod 3 exposes outside valve body 1 and with handle 7 and is connected; Valve body 1 side and water outlet interface 5 are connected as a single entity, and the lower end of valve body 1 is connected as a single entity with water inlet interface 4, and valve body 1 is whole the manufacturing with water inlet interface 4 and water outlet interface 5, preferably adopts PVC (PVC Polyvinylchloride) to make.Expander 6 is fixedly mounted on the spool 2 near the one side of valve rod 3, and for guaranteeing its sealing effect, the height behind expander 6 water-swellables should be more than or equal to the diameter of water outlet interface 5.Expander 6 is made up of water absorbent and infiltration particle, and wherein water absorbent can be selected wood fiber, plant polyphenol water absorbent etc. for use.Water inlet interface 4 exterior edge faces comprise a circle U-shaped caulking groove 41, and caulking groove 41 width are identical with said water pipe 8 wall thickness, and water pipe 8 can be realized direct grafting with water inlet interface 4, and is quick and easy for installation.For guaranteeing to connect sealing and the reliability that water pipe 8 is connected with water inlet interface 4, the degree of depth of caulking groove 41 should be more than or equal to 5mm.
The water-saving irrigation valve of the utility model is work like this: at first rotatory handling 7, and drive valve rod 3 and spool 2, expander 6 move up, thereby are communicated with water inlet interface 4 and water outlet interface 5; If the cavity 11 at water 3 places from water outlet interface 5 reverse osmosis to valve rod is arranged; The space of the cavity 11 at water outlet interface 4 and valve rod 3 places is blocked in expander 6 imbibitions, and then has effectively prevented infiltration outside mounting hole 12; Prevented the loss of water, water-saving and environmental protection.
What present embodiment provided is the structure of single water outlet interface 5, also can adopt the interface of a plurality of water outlet interfaces 5 as required.
The common mounting type of the utility model water-saving irrigation valve is: set up concrete block of wood in the field in farmland; With valve body 1 with protection form ground and double supporting form place in concrete block of wood; Water inlet interface 4 connects with the field that is laid in and water pipe 8 that correspond to concrete block of wood below, and water outlet interface 3 is exposed to outside concrete block of wood with handle 7.The water-saving irrigation valve of the utility model not only is confined to paddy field, and the occasion that also can be suitable for wheatland, vegetable field etc. needs to irrigate is used.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
