本考案は便器洗浄用フラツシユバルブに関し、
特にリモコン操作されたフラツシユバルブの排水
受入部の改良に関する。[Detailed description of the invention] [Field of industrial application] The present invention relates to a flush valve for flushing toilet bowls.
In particular, the present invention relates to improvements to the drainage receiving section of a flush valve operated by a remote control.
第３図について従来の遠隔操作式フラツシユバ
ルブ及びその操作弁の機構を説明する。
With reference to FIG. 3, a conventional remote-controlled flush valve and its operating valve mechanism will be explained.
操作弁１のケーシング２内には流入室３と流出

形成されている。弁棒７の他端には、押しボタン
部７ａが一体的に形成されている。 A partition wall 5 is provided in the casing 2 of the operating valve 1 to separate it into an inflow chamber 3 and an outflow chamber 4. A valve port 6 that communicates both chambers is formed in the partition wall 5, and a valve body 8 corresponding to the valve port 6 is provided on the inflow chamber side at one end of a valve rod 7 that is loosely fitted into the valve port 6.
The valve body 8 is biased toward the valve port 6 by a spring 9 . A push button portion 7a is integrally formed at the other end of the valve stem 7.

て接続されている。 The flush valve body 10 includes a slidable piston valve 15 therein, and is connected to a water supply pipe A and a water discharge pipe B for discharging water to a toilet bowl (not shown). Pressure chamber 11 of flush valve body 10
The discharge chamber 12 is connected to the inflow chamber 3 and outflow chamber 4 of the operation valve 1 by a primary side pipe 13 and a secondary side pipe 14, respectively.

所定の時間後に弁口１８を閉じる。 When the push button 7a is pressed, the valve port 6 opens and the inside of the pressure chamber 11 of the flush valve body 10 and the discharge chamber 12 are brought into a continuous state. When the internal pressure of the pressure chamber 11 decreases in this manner, the piston valve 15 is instantly pushed into the pressure chamber 11 by the high water pressure within the water supply chamber 16, and therefore opens the valve port 18 and starts flushing. Next, when the push button 7a is released, the valve body 8 closes the valve port due to the restoring force of the spring 9, so that the pressure chamber 11 is sealed. Piston valve 15 rising into pressure chamber 11
As water gradually flows into the pressure chamber 11 through the orifice 17, it gradually descends due to its own weight.
The valve port 18 is closed after a predetermined time.
このように、リモコン式フラツシユバルブは床
又は壁に設けた操作弁１を介して圧力室１１内の
高圧水を放流室１２の排水受入部に排水すること

行なう。 In this way, the remote control flush valve drains the high-pressure water in the pressure chamber 11 to the drainage receiving part of the discharge chamber 12 via the operation valve 1 installed on the floor or wall, thereby draining the water from the discharge pipe B to the toilet bowl. For this purpose, flushing is performed.

が、弁棒７の移動が不円滑になり好ましくない。
However, in the conventional remote control flush valve, the end of the secondary pipe 14 opens into the discharge chamber 12. Therefore, during flushing, a portion of the high-pressure washing water enters the secondary pipe 14 in the opposite direction, flows around the valve stem 7 through the outflow chamber 4, and is fitted into the annular groove around the valve stem 7. It may leak outside beyond the sealing gasket 19. In order to prevent this phenomenon, it is possible to improve the sealing effect of the packing, but this is not preferable because the movement of the valve stem 7 becomes unsmooth.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks. According to the present invention, the flash valve main body is separated into a pressure chamber and a discharge chamber by a slidable piston valve, and the pressure chamber and discharge chamber are connected to the primary piping and the secondary piping, respectively. The high pressure water in the pressure chamber is communicated with the flash valve operation valve through the side piping and the primary side piping.
In the flush valve, which is configured to open the piston valve by discharging water into the discharge chamber via the operating valve and secondary piping, high-pressure water in the pressure chamber is supplied to the drainage receiving section of the discharge chamber. This is achieved by a remote control flush valve that is equipped with a check valve that operates only in the direction in which the water is discharged.
以下、図面に示す実施例に基づいて本考案を説

及び２次側配管１４に連結する。 FIG. 1 shows a first embodiment in which a ball valve type non-return valve 20 is provided in the waste water receiving portion of the discharge chamber 12. As shown in FIG. Inside the housing 21 of the ball valve 20, a large diameter valve chamber 22a and a small diameter valve chamber 22b are formed. Configures the valve seat. Also, large diameter valve chamber 2
An annular groove is bored in the circumferential wall of 2a on the side of the discharge chamber 12, and a C-shaped retaining ring (for hole) 24, for example, is fitted into the groove. Both ends of the housing 21 are connected to the flash valve body 10 via cap nuts 25a and 25b, respectively.
and connected to the secondary side piping 14.

効果が得られる。 The operating valve 1 (Fig. 3) is operated to drain the high pressure water in the pressure chamber 11 into the discharge chamber 12 of the flush valve body 10.
When draining water, the ball 23 is pressed against the C-shaped retaining ring 24, and drainage can be carried out through the gap G between the retaining ring 24. Further, during flancing, the ball 23 is pushed by the water force and pressed against the valve seat, so that the wash water does not flow back toward the operating valve 1. If the inner hole of the retaining ring 24 is polygonal, the inner hole will not be completely blocked by the spherical surface of the ball 23, so that the same effect as the C-shaped retaining ring described above can be obtained.

弁１による排水を行なうことができる。 FIG. 3 shows a second embodiment in which a top-shaped check valve 26 is provided. The valve body 27 is formed to have a polygonal cross section, such as a hexagonal shape, and a single valve stem 28 is formed thereon. Since there is a gap g between the valve body 21 and the inner circumferential surface of the large diameter valve chamber 22a formed in a cylindrical shape, this gap g communicates with the gap G of the C-shaped retaining ring 24, and the operation valve 1 Drainage can be carried out.
Ｃ形止め輪２４を外すことにより逆流防止弁の
保全を容易に行なうことができる。 By removing the C-shaped retaining ring 24, the check valve can be easily maintained.
