DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment. In the stopper box body 1 for communicating the water inlet 2 of the L-shaped stopper box body 1 shown in FIG. 2 and the water outlet 3 open to the ground shown in FIG. A guide piece 7 having a water impulse pressure gradually reducing means and a damage preventing means for relaxing the freezing and expansion pressure is fitted into the water passage 4 in a piece valve 6 suspended at the lower end of the spindle 5. That is, the water impact pressure gradual reduction means divides the peripheral edge of the guide piece 7 into three parts so that the water passage space in the water passage 4 gradually increases or decreases in accordance with the elevation of the spindle 5, and the height difference of the peripheral wall is divided. In addition, the guide piece 7 holds packing 9 between the outer circumference of the piece 8 and the piece base 8, and cooperates with the piece base 8 to release and relieve the freezing and expansion pressure, and to prevent the plug box body 1 and the like. It prevents damage. That is, the breakage preventing means for relieving the freezing and expansion pressure is a communication hole 10 penetrating the bridge 8, a small hole 12 recessed in the shaft portion of the guide piece 7, and a communication hole 11 communicating with the small hole 12. Small ball 1 pressed by spring 13 housed in hole 12
4, an O-ring 15 seated on the bottom surface of the screw hole of the piece base 8 and a ventilation path extending from the outer periphery of the spindle 5 of the piece valve 6 to the communication hole 10 of the piece base 8. The spindle 5 for suspending the piece valve 6 having such a valve structure is screwed into the plug base 16 and constitutes the intake structure b shown in FIG. That is, in the intake structure b, above the position of the water outlet 3, the horizontal holes 17 are vertically formed in two stages in the axial direction of the spindle 5, and the vertical holes 18 are formed by digging the horizontal holes 17 in the axial center. In the adjusting cylinder 19 which is positioned so as to be able to move up and down in response to the descending end of the spindle 5 while axially guiding the air passage and the spindle 5 which communicate with each other, the intake air penetrating laterally from the outer peripheral surface toward the inner peripheral surface is provided. Hole 20 and upper horizontal hole 1
When the 7 and the intake hole 20 communicate with each other, the space 2 provided between the inner diameter of the wide diameter portion 22 of the adjusting cylinder 19 and the outer diameter of the spindle 5 which communicate the lower horizontal hole 17 with the rising pipe 21.
3 and 3. Further, the rising pipe 21 enclosing the spindle 5 is watertightly fitted to the stopper base 16 at the lower portion thereof, and the concave groove 24 on the outer periphery of the tip end is fitted to the protrusion 25 on the inner surface of the insertion hole of the stopper base 16 to form an outer periphery. Is fitted with a fixing ring 26 to prevent it from coming off with a nut 27, and a cylinder 28 having an opening for communicating the water outlet 3 is watertightly fitted thereto via an O-ring at the upper part thereof, and the fixing ring 26 is provided on the outer periphery. It is fitted on the outside and is rotatably prevented by a nut 27. on the other hand,
The adjusting cylinder 19 is vertically and freely water-tightly fitted and screwed into the upper inner surface of the cylinder 28, and is fixed by a positioning set screw 29, and is arranged below the spindle guide surface of the adjusting cylinder 19. Wide diameter part 2
2, the space 23 is formed between the outer diameters of the spindle 5, and the intake hole 20 is located at a position narrower than the space between the upper and lower horizontal holes 17 provided on the spindle 5 from the upper end of the space 23 (equal space). However, a gland 30 for slidingly guiding the spindle 5 is internally fitted and screwed into the upper part of the gland 30, and a cap 31 fitted between the head of the gland 30 and the upper end of the adjusting cylinder 19 is attached to the cap 31. Is fitted with an upper outer cylinder 32 in which the water outlet 3 is projected from the peripheral surface, and the lower end of the upper outer cylinder 32 is a lower outer cylinder 33.
And a lower end of the lower outer tube 33 that is rotatably fitted on the stopper base 16 and a lower end of the lower outer cylinder 33.
It is fixed in place. Incidentally, a hook 36 shown by an imaginary line may be integrated with the middle joint 34, and this hook 36 is used for bundling hoses connected to the water outlet 3 and suspending a brush.

In the antifreezing water faucet pillar a thus constructed, when the spindle 5 is lowered when the drainage is stopped, the guide piece 7 gradually closes the water passage port 4 between them, as shown in FIGS. The packing 37 is detached from the drain hole 38 and the rising pipe 2
The water in 1 is drained from the drain hole 38. At this time, the packing 9 descends in a closed state of the water inlet 4, so that the ventilation passage formed in the spindle 5 above the rising pipe 21 has a water supply pressure. The inside of the riser pipe 21 is communicated with the outside air in a state of being free from heat, that is, the upper horizontal hole 17 is communicated with the intake hole 20 of the adjustment cylinder 19, and the lower horizontal hole 17 is communicated with the space 23. The water is smoothly discharged, and the spindle 5 is moved up during water supply to move the upper horizontal hole 17 above the intake hole 20 to block communication between the horizontal hole 17 and the intake hole 20 and to lower the lower hole. The horizontal hole 17 of the upright pipe 2 is moved upward from the upper end of the space 23 to block the communication between the horizontal hole 17 and the space 23.
The inside of 1 is completely shut off from the outside air, and the water passage 4 is gradually opened by the water impulse pressure gradual reduction means of the guide piece 7, and the water passed through the water inlet 2 passes through the rising pipe 21 and has a preselected direction. It is used for water distribution by being guided to the water outlet 3 that opens at the. Therefore, in the intake structure b, the timing of water supply / drainage and the timing of opening / closing the ventilation passage can be adjusted by adjusting the position of the adjustment cylinder 19, so that the structure is simplified and water is not introduced into the ventilation passage. Since there is no intake failure due to freezing of the passage, the water in the riser pipe 21 is drained cleanly regardless of whether the faucet is open or closed when the drainage is stopped, and a complete antifreeze state can be maintained.
Further, even if the water remaining in the body 1 of the stopper box containing the piece valve 6 freezes, the freezing and expanding pressure prevents a part of the residual water from escaping from the communication hole 11 of the guide piece 7 to prevent damage. It is alleviated by the means, and the life of the stopper box body 1 is extended. Next, when explaining the work at the time of checking the water supply / drainage valve part,
By removing the handle 39 and the gland 30 from the spindle 5 and removing the joint forming the water outlet 3 from the peripheral surface of the upper outer cylinder 32, the upper outer cylinder 32 can be removed from the middle joint 34, exposing the upper part of the rising pipe 21. You can If you turn this rising pipe 21 in the direction opposite to the screwing direction with a pipe wrench,
The stopper base 16 also rotates together with the piece valve 6 and can be pulled out from the stopper box main body 1, which reduces maintenance work.

[0008]

As described above, according to the present invention, the water intake pressure gradual reduction means and the outside air of the ventilation passage are made to cooperate with each other so that the intake structure is simplified and the damage prevention means of the prior art is realized. Achieves enhanced antifreeze function and improved durability,
There is an effect that a more reliable antifreeze faucet pillar can be provided at a lower cost.
