As described above, in the water shutoff valve 5 of the present invention, the male screw 5 is provided at the upstream side connecting portion 5a of the water shutoff mechanism 5e.
Since d is formed into a screw-in type and the simple connection port 5d is integrally formed at the downstream side connection end portion 5c of the water stop mechanism 5e, this water stop valve 5 is screwed continuously to the water supply pipe 4. Only then, the simple connection port joint 3 can be detachably connected to the water supply pipe 4 via the water shutoff valve 5. In addition,
A water shutoff valve 5 similar to that on the water supply side is also formed on the hot water supply side.

As described above, the simple connection port 5d is provided on the downstream side of the water stop mechanism 5e so that the simple connection port joint 3 can be connected. The pipes can be attached and detached, and the time and labor required for not only new construction of the faucet such as the hot and cold water mixing tap 1 but also repair or replacement thereof can be minimized.

Further, since the connection portion on the upstream side of the water stop mechanism 5e is of a screw type, the connection does not easily come off, and when the main tap of the water supply is open, the operator can There is no possibility that the water shutoff valve 5 is accidentally removed from the water distribution pipe 4. It should be noted that, for example, an operator may mistakenly disconnect the water shutoff valve 5 and the pipe 2 when the water main valve is opened and the water shutoff valve 5 is opened. Even if there is, the water discharge can be stopped and the damage can be minimized by turning the handle 5f of the water stop valve 5 in front of the operator to close the water stop valve 5. . In addition, in order to avoid such a situation, the water shutoff valve 5
It goes without saying that an automatic water blocking mechanism may be formed on the downstream side connection end portion 5c.

In addition, it is possible to reduce the number of threaded connection portions that require time and labor for installation work. In other words, by using the water shutoff valve 5, the work performed by the operator can be simplified as much as possible particularly in new construction work, and there is no fear of water leakage due to unnecessary connection.

Then, as in this embodiment, the water shutoff valve 5
In the case where the upstream side connecting portion 5a and the downstream side connecting end portion 5c are arranged at a right angle, as described in this embodiment, from a pipe such as the water pipe 4 having the connecting end portion formed on the wall surface. 90 °
You can connect the simple connection port joint 3 by changing the angle,
The piping such as the water supply flexible tube 2 can be simplified.

In place of the water shutoff valve 5 of this embodiment,
By using the water shutoff valve 6 shown in FIG. 3, the positional relationship between the upstream side connecting portion 6a and the downstream side connecting end portion 6c of the water shutoff valve 6 can be arranged linearly. By doing so, the cap nut 6b is screwed into the water supply pipe or the hot water supply pipe protruding from the floor surface of the sink or the like to connect and connect the water shutoff valve 6 without changing the direction of water supply or hot water supply. The simple connection port 6d can be provided, and the simple connection port joint 3 can be arranged on a straight line to simplify piping such as the flexible pipe 2 for water supply. The other construction of the water shutoff valve 6 is the same as or equivalent to that of the water shutoff valve 5, and thus detailed description thereof will be omitted.

FIG. 4 is a side view showing an embodiment of the water stopcock of the present invention. In FIG. 4, 7 is a faucet with a simple connection port, in which a male screw portion 7b is formed at a connection portion 7a between the faucet 7 and the water pipe, and a simple connection is made at an open end portion 7c of the faucet 7. The mouth 7d is integrally molded. 7e is a water stop mechanism of the water faucet 7, and 7f is a handle for operating the water stop mechanism 7e. The detailed structure of the water stop mechanism 7e is the same as the water stop mechanism 5e of the water stop valve 5, but needless to say, the present invention is not limited to this structure.

According to this embodiment, the faucet 7 with a simple connection port is provided.
Since the open end 7c is the simple connection port 7d, there is no need to provide a special connection portion for providing the simple connection port 7d at the tip of the faucet 7, and the simple connection integrally formed with the faucet 7 For example, a fully automatic washing machine or a hose with a simple connection port joint such as a sprinkler can be connected to the port 7d with one touch. Therefore, by connecting the faucet 7 to the simple connection joint, water can be extremely easily supplied to equipment such as a fully automatic washing machine and a sprinkler.

Further, since it is not necessary to attach anything special to the end of the faucet 7, it looks good, the cost can be suppressed, and there is no risk of water leakage due to unnecessary connection. Further, since the connection of the faucet on the upstream side of the water stop mechanism is a screw type, an accident such as a user accidentally removing the faucet does not occur.

In each of the above embodiments, the simple connection port joint 3 connected to each of the simple connection ports 5c, 6c and 7c is
A safety device may be formed to prevent the valve or the faucet 5, 6, 7 from coming off when the water is not stopped, that is, when water pressure is applied. By doing so, it is possible to prevent an accident that the user accidentally removes the simple connection joint 3 with the water shutoff mechanism fully opened. 5 and 6 are cross-sectional views showing, as an example, the states in which the simple connection port joint 3 having the safety device formed on the valve 5 is connected, and FIG. 5 shows the water blocking mechanism 5e (see FIG. 2) of the valve 5 opened. FIG. 6 shows a state in which water is being supplied, and a state in which the simple connection port joint 3 is about to be removed while the water stop mechanism 5e of the valve 5 is open.

5 and 6, the simple connection port joint 3 is provided with a substantially cylindrical inner pipe 3a, a substantially cylindrical outer pipe 5b circumscribing the inner pipe 3a, and locking provided at various places of the inner pipe 3a. In addition to the basic structure including the ball 3c, a check valve 30 provided on the downstream side of the inner pipe 3a, a perforation 31 penetrating the inside and the outside of the inner pipe 3a on the upstream side of the check valve 30, and the perforation 3
1 is provided with a valve body chip 33 having a sealing function that is rotatable around the support shaft 32 and a pressing tip 34 that weakly presses the valve body chip 33 toward the inner peripheral side.

Therefore, in the simple connection port joint 3 with the safety device, water is supplied with the check valve 30 open while the water stop mechanism 5e (see FIG. 2) of the valve 5 is opened to supply water. Water flows as shown by an arrow A in FIG. 5, and the valve body chip 33 is pushed by the inner peripheral surface of the outer pipe 3b to form the perforation 3
Blocking 1.

Then, the water shut-off mechanism 5e (see FIG. 2) of the valve 5 is opened and water is supplied to the outer pipe 3b.
When attempting to remove the simple connection port joint 3 by sliding on the valve body, the water pressure shown by the arrow B in FIG. The tip 31 regulates sliding of the outer tube 3b. in this way,
By forming a safety device in the simple connection port joint 3,
Simple connection port joint 3 with the user fully opened valve 5
It is possible to prevent the accident of accidentally removing. On the other hand, when the water shut-off mechanism 5e of the valve 5 is closed, the check valve 30 is closed, so that a hose or the like is connected to the downstream side of the simple connection port joint 3 and the water pressure C (FIG. 6). Even if the valve is in the closed position, the valve body chip 33 is not pressed by this, and the simple connection port joint 3 can be easily removed.

The simple connection port joint 3 with the safety device is not limited to the one connected to the valve 5 described above, but may be a valve or a faucet of another shape (for example, the valve 6 or the water of the present invention). It can be used for the simple connection port joint 3 connected to any simple connection port formed or attached on the downstream side of the stopper 7).
