Abstract
The utility model relates to a self-closing valve hydrant, consisting of a hydrant body, a connector, a main valve, an auxiliary reset spring, an internal valve, an internal valve spring and a water receiving pipe, wherein the hydrant body is arranged on the pipe orifice of an outlet pipe, the orifice part of the hydrant body is connected with the connector, and the water receiving pipe and the hydrant body can be integrally connected through the connector; the main valve is arranged at the joint of the hydrant body and the connector, the auxiliary reset spring is sleeved outside the main valve, the inner part of the main valve is a cavity, the internal valve is arranged inside the cavity, and the back end of the internal valve is provided with the internal valve spring. When working, the water receiving pipe is inserted in the hydrant body and is fixed through the connector; at this moment, the front end of the water receiving pipe is raised to push the internal valve and the main valve backwards in sequence, the auxiliary reset spring and the internal valve spring are in the state of compression, and the outlet of the hydrant body is opened for water irrigation through the water receiving pipe. The self-closing valve hydrant is suitable for diversified irrigation manners, and the operation is simple and convenient.
Description
Technical field:
The utility model relates to jaws equipment field, field irrigation pipeline network waterexit end, specifically is the self closing stop valve hydrant.
Background technique:
At present country attaches great importance to construction of water conservancy works, annually drops into a large amount of manpower and materials and tradition is dug the canal diversion trench digging mode of irrigating that discharges water transforms, and has realized the water-saving irrigation mode of various ways.Its various forms of water-saving irrigation modes are perfect constantly, and new technology, new equipment continue to bring out, and new equipment more trends towards towards water saving, safety, easy theory easily.Present common pre-buried underground pipe network irrigation installation, hydrant is left in the field, to realize taking over the Infrastructure of irrigation practices such as flood irrigation, sprinkling irrigation, drip irrigation, pouring filling.Hydrant is to open to supply water, and closed sealing is set up interface.At present key adopts the ball valve, butterfly valve of stop valve, gate valve and the rotation form of screw rod pressing etc. mostly.These equipment and the protection of technological pipe network are installed and are acquired a certain degree of difficulty, and use operation also inconvenient.
Summary of the invention
The utility model overcomes the deficiency that existing technology exists, and adopts new design concept, has designed the self closing stop valve hydrant.The said self closing stop valve hydrant of the utility model, valve is opened water supply automatically in the adapter process, removes " the self-closing hydrant " that utilize the pressure automatic cut-off of water in the pipe network behind the pipe.
The technological scheme of the utility model: self closing stop valve hydrant; Form by feedwater key, connecting head, main valve, spring-assisted reduction, internal valve, interior valve spring, water receiving pipe; Wherein, The feedwater key is installed on the mouth of pipe of outlet pipe, and the oral area of feedwater key is connected with connecting head, and connecting head can be connected one with the feedwater key with water receiving pipe; Main valve is established at joining portion at feedwater key and connecting head, and the outside of main valve is with spring-assisted reduction, and main valve inside is a cavity, dress internal valve in the cavity, and the rear end of internal valve is provided with interior valve spring.During work, with fixing in the water receiving pipe insertion feedwater key and through connecting head, this moment, the front end protrusion of water receiving pipe promoted to move behind internal valve and the main valve successively, and spring-assisted reduction and interior valve spring are compressive state, and feedwater key water outlet is opened, to water receiving pipe water supply irrigation.
The utility model is pipeline network construction adaptable across the farmland, adapts to diversified irrigation method, and is simple to operation.
Description of drawings
Fig. 1 is this suitable new structure schematic representation;
Fig. 2 is the utility model working state schematic representation.
Wherein: 1, feedwater key 2, connecting head 3, main valve 4, spring-assisted reduction 5, internal valve 6, interior valve spring 7, water receiving pipe
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.Like Fig. 1, feedwater key 1 is installed on the mouth of pipe of outlet pipe, and the oral area of feedwater key 1 is connected with connecting head 2, and connecting head 2 can be connected one with feedwater key 1 with water receiving pipe 7; Establish main valve 3 at the feedwater key 1 and the joining portion of connecting head 2, the valve body outside of main valve 3 is with spring-assisted reduction 4, and main valve 3 inside are a cavity, establish internal valve 5 in the cavity, and the rear end of internal valve 5 is provided with interior valve spring 6.As shown in Figure 2, during work, insert in the feedwater key water receiving pipe 7 also fixing through connecting head 2; This moment, the front end protrusion of water receiving pipe 7 promoted to move behind internal valve 5 and the main valve 3 successively; Spring-assisted reduction 4 is compressive state with interior valve spring 6, and feedwater key 1 water outlet is opened, and supplies water for water receiving pipe 7 and irrigates.
