栓に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a check valve-equipped water faucet, and more particularly, to a check valve-equipped water faucet whose left and right usability can be changed.
【０００２】[0002]

常のバルブの他に逆止弁を直列に配置する。2. Description of the Related Art As is well known, in the definition of JIS standard, a water faucet is a water faucet (valve) used when a water supply pipe (branch pipe) is branched from a water distribution pipe. On the other hand, when branching a water supply pipe from a water distribution pipe or a faucet, a check valve is generally arranged in series in addition to a normal valve.
【０００３】ところで、この逆止弁は、水道水の、その

流の方向が決まってしまい、以下のような不都合が生じ
る。By the way, since this check valve is a valve adapted to prevent reverse flow of tap water due to its back pressure (see, for example, Japanese Utility Model Laid-Open No. 4-52609), the check valve is used. If they are integrated together, the direction of the water flow in the water faucet is determined, and the following inconvenience occurs.
【０００４】これを、前掲の実開平４−５２６０９号公

に回動操作することにより、ボ−ル弁体３の向きを変え
て弁開閉する。This will be described with reference to the ball valve with a check valve shown in Japanese Utility Model Laid-Open No. 4-52609. Figure 4
In the figure, reference numeral 1 denotes a valve box integrally formed with an inflow side joint portion 2, and a ball valve element 3 is provided in the valve box 1 so as to horizontally turn in a right angle range. A single lever-4 is fixed to the upper portion of the ball valve body 3, and the single lever-4 is horizontally rotated, for example, in the front of the drawing to rotate the ball valve body. Change the direction of 3 and open / close the valve.

あるが、この公報では、弁箱１に流出側ジョイント部５
を取付け、この流出側ジョイント部５内にスプリング６
で押圧される逆止弁７を設けている。Although the above structure is a ball valve which is very common, in this publication, the outflow side joint portion 5 is attached to the valve box 1.
Mount the spring 6 inside the outflow side joint 5.
A check valve 7 that is pressed by is provided.

すれば、壁面に突当る等）があれば、この逆止弁付ボ−
ル弁の流入側と流出側とを左右の向きを単に変えると逆
止弁が作動しなくなる、という不都合がある。Therefore, in such a ball valve with a check valve, the left side (in the direction of the anti-thick arrow) in the figure is set to the upstream side for convenience of piping, and the working space of the single lever-4 is restricted (for example, a single lever-4). If the lever-4 is horizontally turned to the opposite side in the figure, it will hit the wall surface, etc.)
However, if the left and right sides of the inflow side and outflow side of the valve are simply changed, the check valve will not operate.

る。Therefore, in general, for the ball valve with a check valve, it is necessary to prepare two types of valves, that is, the left valve and the right valve, which are easy to use. Such inconvenience is particularly remarkable when the water valve with a check valve is used in a limited space such as an apartment.

In a T-shaped water faucet in which a cylindrical valve body connected to a pipe is detachably coupled so that the left and right directions of the valve hub can be changed, a check valve is provided on one side of the valve hub, and a valve is provided. A water valve with a check valve is characterized in that a disc valve made of ceramics is provided on the main body so that a knob type handle is pivotally operated on the outer periphery of the valve main body so as to be locked / rotated on the outer periphery of a movable disc.
