DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intake valve used in cold regions, and in particular,
The present invention relates to a dual valve structure intake valve that can be used for both horizontal and vertical piping.

Conventionally, in cold districts, antifreeze water taps are used to drain water from pipes during the winter, but as shown in Fig. 1,
In so-called gate type pipes (also called torii type pipes) having upper and lower bent portions, when the antifreeze water tap A is operated to drain water, a negative pressure is generated in the pipes and complete drainage is possible. Instead, it caused freezing. Therefore, a method has often been used in which an intake valve is attached to an arbitrary place of the horizontal pipe a or the vertical pipe b, and when the water is drained, the inside of the pipe is automatically opened to the atmosphere to eliminate the negative pressure and prevent freezing.

A conventional example is shown in FIGS. 2 and 3, and FIG. 2 shows an intake valve for a horizontal pipe, which is vertically connected to the upper end of cheese c connected to the horizontal pipe a. An O-ring f is attached to the lower end valve seat e of the valve box d connected to the cheese c, and the main valve body h, which is given a rising force by the spring g, seals the valve box d so that pressure water is stored in the valve box d. I try not to get in. A valve lid i is connected to the upper end of the valve box d, and an O-ring 1 serving as a valve seat of an auxiliary valve body k that is normally seated on a pedestal j is attached. The auxiliary valve body k uses a plastic ball whose specific gravity is smaller than 1, and if water should leak from the main valve body h, the auxiliary valve body k will rise by buoyancy and contact the O-ring l. To prevent water leakage.

FIG. 3 shows an intake valve for a vertical pipe, in which a cheese c connected to a vertical pipe b is connected to an elbow-shaped valve box d, and a valve box joint m for accommodating a main valve body h on the inlet side of the valve box d. Are connected horizontally by an O-ring n so as not to separate while also functioning as a seal.
A pedestal j is vertically connected to the outlet side of the valve box d, a valve lid i is connected to the pedestal j, and an auxiliary valve body k is housed between the two. By any chance
Even if water leaks from the main valve body h, the auxiliary valve body k rises due to buoyancy and stops water, as in the case of FIG.
Since the auxiliary valve body k is normally separated from the O-ring 1 which is the valve seat, there is an advantage that the intake resistance when draining water is small and therefore the water in the pipe is easily removed without remaining.

As described above, in the conventional intake valve, since the valve has a double structure, there is an advantage that there is almost no water leakage accident, but on the other hand, two types are required, one for horizontal pipes and one for vertical pipes. In addition, it is inconvenient for the producers, and especially for vertical pipes, it is complicated and costly. Furthermore, since the intake valve operates only when the antifreeze water tap is used in the winter period, the O-ring f is connected to the valve seat e for a long period of time because it is pressed by water pressure, and the two stick to each other. However, even if I tried to drain water by operating the antifreeze tap, there was an accident that the water did not drain.

Therefore, in the present invention, when the auxiliary valve element is used for a vertical pipe, the auxiliary valve element is held by a weak spring having a diameter larger than that of the main valve element so that the auxiliary valve element comes into contact with the valve seat. The purpose is to provide an intake valve that can be used for any vertical piping.Furthermore, the malfunction of the valve due to valve sticking can cause the main valve body and the main valve seat to be pressed with the largest diameter possible, and the main valve body and the main valve can be pressed. The prevention is made by forming one of the seats with a tetrafluoroethylene resin.

In FIG. 4, the valve box 1 has an O-ring groove 2 having a small diameter on the lower side and having a small diameter on the lower side, and the O-ring 3 is housed so as not to separate, and the lower end of the O-ring 3 is inserted into the main valve seat 4 And Reference numeral 5 denotes a main valve body made of tetrafluoroethylene resin such as Teflon (registered trademark), which is held upward by a main valve spring 6 via a split collar 7. Reference numeral 8 is a communication hole for opening the inside of the pipe to the atmosphere, but in the normal state, the main valve spring 6 and the main valve body 5 are in close contact with the valve seat 4 due to water pressure to interrupt the communication. A valve lid 9 is connected to the upper end of the valve box 1, and a water blocking cap 11 is screwed to the valve lid 9 via a water blocking clip 10 so as to be vertically movable. Valve lid 9
Partially cut out the upper outer peripheral portion and the lower inner peripheral portion to form an upper air flow passage 12 and a lower air flow passage 13. Upper air passage
A space between 12 and 13 is projected inward to form a downward auxiliary valve seat 14, and an auxiliary valve body 16 having an O ring 15 mounted between the auxiliary valve seat 14 and the main valve body 5 is used as a base for the valve box 1. It is held upward by an auxiliary valve spring 17 that operates. Since the auxiliary valve body 16 has the cylindrical guide portion 19 having the notch 18 at the lower end, the auxiliary valve body 16 can be smoothly moved up and down at a fixed position, and if the main valve body 5 leaks water. Also, when the rising water exceeds the notch 18, the air inside the guide portion 19 is compressed and the auxiliary valve body 16
Floats and the O-ring 15 comes into close contact with the valve seat 14 to stop water leakage. That is, even if the auxiliary valve body 16 is not made of a material having a specific gravity smaller than 1, the auxiliary valve body 16 becomes a floating valve as in FIGS. Therefore, a gap may be provided between the auxiliary valve seat 14 and the O-ring 15, and when the intake valve is attached to the vertical pipe, that is, when the intake valve is placed sideways, the valve seat
Since the auxiliary valve spring 17 that is weak enough to contact the O-ring 15 with the 14 is used, there is no water leakage from that part even when the vertical pipe is attached, and the intake resistance when draining is reduced by that much, so the residual water amount in the pipe When it is attached to a horizontal pipe, that is, when it is oriented vertically as shown in the figure, the auxiliary valve body 16 descends by its own weight, and a gap is created between the O-ring 15 and the auxiliary valve seat 14. As I said, it doesn't matter.
Since the auxiliary valve spring 17 has a larger diameter than the main valve spring 6 and the split collar 7, it does not adversely affect the operation of the main valve body 5, and the overall length is short and compact. can do. The water stop clip 10 has a shape as shown in FIG. 5, and can be attached to and detached from the valve lid 9 by utilizing the elasticity of plastic. That is, by any chance, the main valve body 5,
When water leaks from both the auxiliary valve bodies 16, the water stop clip 10 is pulled out and the water stop cap 11 is lowered to stop the water.

次に作動態様について説明する。 Next, the operation mode will be described.

When water is drained from the normal state shown in Fig. 4 by the antifreeze water tap A in Fig. 2, water begins to be discharged into the vertical pipe b due to the drop, but at that time, the pressure in the pipe tends to become negative, A pressure difference occurs between the upper and lower parts of the main valve body 5. Therefore, the main valve spring 6
The main valve body 5 descends while compressing the
Also compresses the auxiliary valve spring 17 and lowers it. The air passes through the upper and lower air flow passages 12 and 13 and the notch 18, passes through the communication hole 8 and enters the pipe to eliminate the negative pressure. The strength of the main valve spring 6 and the auxiliary valve spring 17 is set in advance so that water can be drained to a position where the water remaining in the pipe does not freeze. When the intake is finished, the restoring force of the springs 6 and 17 restores the state of FIG. Since the intake valve operates only during the freezing period,
Since the state in which the main valve body 5 presses the O-ring 3 by the water pressure continues, the main valve body 5 and the O-ring 3 are fixed to each other,
In the meantime, even if the antifreeze water tap is operated to drain water, it may lead to an accident that water does not escape because the intake valve does not operate. However, in this embodiment, the main valve seat 4 has a large diameter as much as possible. Is configured to increase the descending force of the main valve body 5 due to the pressure difference, and because the intake valve body 5 uses tetrafluoroethylene resin, due to its excellent non-adhesiveness, Accidents due to sticking can be effectively prevented.

次に、第6図に本考案の他の実施例を示すが、図中、

That is, in the case of FIG. 4, the valve box 1 and the valve lid 9 are separately formed and connected, but in the present embodiment, the valve box 1 is an integral body, and from the bottom to the lower end. Insert the valve seat body 20 made of tetrafluoroethylene resin having the valve seat 4 into the O-ring 21.
This also serves as a seal so that it will not easily come off. The main valve body 5 has an O-ring 3 mounted in a groove portion 2 provided on the outer circumference thereof, and a communication hole 8 of FIG.
Instead of the above, several cutouts 23 are provided to form an air passage. An O-ring is attached downward to the upper portion of the valve box 1 to form an auxiliary valve seat 14. To close the auxiliary valve seat 14,
A semicircular auxiliary valve body 16 formed of a resin having a specific gravity of less than 1 is held by a weak auxiliary valve spring 17 which is in contact with the valve seat 14 when it is mounted vertically, that is, when installed sideways. . Valve seat when mounted vertically on a horizontal pipe
Although there is a gap between the auxiliary valve body 14 and 14, there is no effect of compressing the air as shown in FIG. 4 even if there is water leakage from the main valve body 5, but the auxiliary valve body 16 rises due to buoyancy and stops water. The same is true.
The other operation modes are the same as those in FIG.

When installing the horizontal pipe, the auxiliary valve body does not contact the valve seat,
When water enters the valve chamber, it floats and contacts the valve seat.
With a floating valve structure, when the vertical pipe is attached, the auxiliary valve body is held using a weak auxiliary valve spring that contacts the valve seat only when the weight of the auxiliary valve body is lost. The amount of water remaining at the time is reduced, and the risk of freezing is reduced accordingly. In other words, it can be used for both horizontal and vertical piping.

The auxiliary valve spring surrounds the main valve spring and the upper end of the main valve body. Therefore, the valve box can be shortened by that amount, and the auxiliary valve spring must be weaker than the main valve spring to increase the intake capacity as much as possible. There is an advantage that the variation is small and the dimensional accuracy is good.
