Described valve rod is screwed onto and connects in the chamber, and drive unit is the handle that is connected the valve rod upper end.
Institute's upper piston is connected the valve rod lower end, and the upper piston lower end is connected with middle piston upper end by the pull bar that passes the connecting tube inner chamber, and middle piston lower end is connected with the lower piston upper end by lower link.
The lower end of described down valve body is provided with the linkage section that can connect waste pipe, the inner chamber of linkage section be communicated with drain opening and size greater than drain opening.
Following valve body placed its water intake is communicated with running water pipe can use.Piston and lower piston rose during actuate valve stem drove during water supply, lower piston rises drain opening is sealed, middle piston rises water intake is communicated with the following chamber that connects, water is just entered down by water intake and connects the lower end, chamber, arrive through bypass cavity then and connect the upper end, chamber down, and then arrive to go up through connecting tube and connect the chamber and finally flow out through water outlet; Water supply finishes, piston and lower piston decline during actuate valve stem drives, and lower piston descends drain opening is opened wide, and middle piston decline blocking-up water intake connects being communicated with of chamber with following, and the water in upper valve body and the connecting tube is under the effect of gravity, through bypass cavity and drain opening discharge; In the said process upper piston also the chamber section above last perforation chamber is positioned at water outlet move or move down on valve rod.
The utility model just can be realized supplying water and air emptying function by moving of two-piston in the following valve body by the combination of upper valve body, connecting tube and following valve body three parts.Therefore, the utlity model has the convenient and low advantage of working service cost of simple in structure, fitting operation, can bring out the valve water, close the antifreeze beneficial effect of valve.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of the utility model water supply state;
Fig. 2 is the structural representation of the utility model emptying state.
Embodiment
As depicted in figs. 1 and 2, antifreeze hydrant comprises upper valve body 1 and following valve body 2, is provided with vertical going up in the upper valve body 1 and connects chamber 3, and a side of upper valve body 1 is provided with to be communicated with and goes up the water outlet 4 that connects chamber 3.Be provided with vertical following perforation chamber 5 in the following valve body 2, one side of following valve body 2 is provided with to be communicated with and connects chamber 5 water intakes 6 down, under to connect 5 lower ends, chamber be drain opening 7, the lower end of following valve body 2 is provided with the linkage section 17 that can connect waste pipe, the inner chamber communicated drainage mouth 7 of linkage section 17, the inner cavity size of linkage section 17 also is provided with communicated drainage mouth 7 and the following bypass cavity 11 that connects 5 upper ends, chamber greater than the mouth of a river 7 in the following valve body.Upper valve body 1 and following valve body 2 are connected the connecting tube 8 that the perforation chamber 3 lower end the other ends are connected down perforation 5 upper ends, chamber by an end and link together.The upper end in last perforation chamber 3 is connected with valve rod 9 moving up and down, and moving of valve rod 9 driven by drive unit.Valve rod 9 can be screwed onto and connect in the chamber 3, the drive unit of actuate valve stem 9 can be affixed in the top handle 10 or the motor that is connected with its power; Valve rod 9 also slidably is connected and connects in the chamber 3, and the drive unit of actuate valve stem 9 can be selected the motor that can make fore and aft motion for use.Sealing is housed in the last perforation chamber 3, and it is positioned at the upper piston 12 of the chamber section of water outlet 4 tops, and middle piston 13 that cooperates with its liquid sealing and water intake 6 can be sealed and the lower piston 14 that drain opening 7 can be sealed are housed in the following perforation chamber 5.Upper piston 12 is by swivel nut 18 and the cooperation realization of back-up ring 19 and being connected of valve rod 9, be that valve rod 9 lower end part kinks have swivel nut 18, swivel nut 18 is installed on that the back-up ring 19 of valve rod 9 lower ends is spacing on valve rod 9, and valve rod 9 is free to rotate in swivel nut 18, and swivel nut 18 is screwed onto on the upper piston 12.When valve rod 9 spirals rise, promote swivel nut 18 by back-up ring 19 and drive upper piston 12 risings; When valve rod 9 spirals descend, drive upper piston 12 by the compressing of the convex shoulder on the valve rod 9 swivel nut 18 and descend.Valve rod 9 benefit free to rotate in swivel nut 18 is: the spiral lifting of valve rod 9 can only bring the axial displacement of upper piston 12, and upper piston 12 is rotated, so that do not cost power during handle with sleeve.Upper piston 12 lower ends are connected with middle piston 13 upper ends by the pull bar 15 that passes connecting tube 8 inner chambers, and middle piston 13 lower ends are connected with lower piston 14 upper ends by lower link 16.
