である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stop valve that controls the supply of hot water or water using a mixing valve or the like, and particularly relates to a structure that prevents backflow.
［従来の技術］
従来より、ミキシングバルブ等は外部より供給される一
般市水と熱水をパルプ操作によってそれらの混合比を変

によって圧力がばらついたり変動しｔこすすることが多
いため、ミキシングバルブを介して相互に逆流すること
を防止するのに逆止弁を一般市水と熱水の供給配管に夫
々設置することが一般的である。By the way, the pressure of supplied municipal water and hot water often fluctuates and rubs depending on the environmental conditions of the supply source, so a check valve is used to prevent them from flowing back into each other through a mixing valve. It is common to install them separately in the supply piping for municipal water and hot water.

用も兼ねている）を設置することが多かった。Also, if the pressure difference between the two supply sources is too large, when adjusting the hot water temperature at the mixing valve, the hot water temperature will fluctuate greatly even with just a slight adjustment of the nozzle. There was a problem that A adjustment was difficult. For this reason, each supply pipe is often equipped with a flow rate regulating valve (which also functions as a water stop valve) to improve the pressure balance.

Even if the flow attempts to flow backward from the downstream side to the upstream side in this state, the spring force of the spring member 6 will cause the valve body 3 to
is seated in the valve hole 2 to prevent backflow.

This is provided. A valve body 3 is disposed on the downstream side of the valve hole 2 (on the water outlet 8 side) so as to be able to approach and separate from the valve body 3, and a valve rod 11 is integrally provided above the valve body 3. A female threaded cylinder portion 12 is provided above the valve body 3 of the valve body 1, and this female threaded cylinder ji1
A male thread portion 13 on the outer periphery of the valve holder 5 is screwed onto the valve holder 2.
By rotating the valve holder 5, the valve holder 5 is moved up and down. The stopper rod 4 is placed above the valve holder 5.
A stopper rod 4 is made to protrude outside from the valve body 1, and a handle 14 is attached to this protruding portion.

いる。The spring member 6 is a coil spring in this embodiment, and is interposed between the valve body 3 and the valve holder 5 on the outer periphery of the valve stem 11 (f), so that the valve body 3 is seated in the valve hole 2. It is energized as follows.

ら離座することで開栓状態になる。The operation of the water stop valve configured as described above will be explained as follows. When the handle 14 is rotated in one direction by the user, the stopper rod 4 rotates and the valve holder 5 also rotates and spirals downward, and as the valve holder 5 descends, the valve stem 11 is pushed. The valve body 3 is seated in the valve hole 2 and is in an open state. Furthermore, when the handle 14 is rotated by the user in the opposite direction, the valve holder 5 spirals upward, creating a gap between the valve stem 11 and the valve holder 5, which causes water to leak from the water inlet lower part. The valve body 3 is pushed up by the pressure of , and the valve body 3 is separated from the valve hole 2 to be in an open state.

However, due to the tension of the spring member 6, the valve body 3 is seated in the valve hole 2, thereby preventing the backflow. In other words, the single valve element 3 is a valve that has a check valve function in addition to the conventional stop valve function.

することができる。Next, the embodiment shown in FIG. 2 will be described. In this embodiment, a cylindrical strainer 15 is disposed upstream of the valve hole 2 (lower water inlet side) so that the strainer 15 can remove dust from the water supply, hot water supply source, and piping. Removal of dust may cause clogging of dust, temperature of mixing valve, etc.
119 defects can be prevented. An inspection lid 16 is screwed onto the valve body 1 below the strainer 15, and a knob 1
7 to remove the inspection M16, and the accumulated dust can be easily discharged to the outside. Further, a drain plug 18 is provided on the side of the valve body 1, as shown in FIG. An outer cylinder 19 of the drain valve 18 is attached by screwing through an O-ring 20, and a plug body 22 having a valve seat packing 21 at the tip is screwed into the outer cylinder 19. A knob 23 is provided in the outer cylinder 19, and a water drain port 24 is provided in the outer cylinder 19. When the user holds the knob 23 and turns it in the direction to remove the plug 22, the valve seat gasket 21
is removed from its seat, and the water in the valve body 1 is discharged to the outside from the water drain port 24. If water can be drained in this way, freezing damage can be prevented in the winter. In this embodiment, the strainer function and water draining function can be integrated into the valve body 1, so less space is required for cleaning, and maintenance is simple as only one inspection is required, and it is more compact. and cost reduction.
