Conventional water stop valves, such as the standards of the Japan Water Works Association
The structure of the JWWA, B-108 water stop valve has a screw-in type stopper rod, and a movable seal mounting piece is provided at the lower end of the stopper rod. Then, when the stopper rod is raised, the top is pushed up by water pressure and becomes open, and when the stopper rod is lowered, the top blocks the water inlet and becomes closed.
また、特開昭51−24830号公報には、こまにコ
イルバネによる背面押圧力を加えた形式のものが
示されている。 Further, Japanese Patent Application Laid-Open No. 51-24830 discloses a type in which a back pressing force is applied to the top by a coil spring.
更に、実開昭60−7477号公報には、栓外に圧力

［考案が解決しようとする課題］
ところが、前記従来の止水栓には、どれにも次
のような欠点がある。即ち、協会規格の止水栓で
は、こまが単に自重のみによつて下方へ付勢され
ているだけだから、逆流防止機能が充分でない。[Problems to be Solved by the Invention] However, all of the conventional water stop valves have the following drawbacks. That is, in the stop valve of the association standard, the stopper is simply urged downward by its own weight, and therefore does not have a sufficient backflow prevention function.
また、特開昭51−25830号のものでは、コイル
バネによつてこまの背面に付勢を加えているの
で、逆流防止機能は一応充分であるが、１次側か
ら力を受けた時の、こまの上昇応答が速すぎ、水
撃や脈動などを吸収緩和する能力を持たない。 In addition, in JP-A No. 51-25830, a coil spring applies force to the back of the top, so the backflow prevention function is sufficient, but when a force is applied from the primary side, The rising response of the top is too fast, and it does not have the ability to absorb and alleviate water hammer and pulsation.
更に、実開昭60−7477号のものでは、水圧計が
付設されているので、栓内の水圧の測定は可能で
あるが、栓室内に受圧部（ダイヤフラム）を設け

の上、水圧計を自由に取外すことができない。 Furthermore, since the model of Utility Model Application Publication No. 60-7477 is equipped with a water pressure gauge, it is possible to measure the water pressure inside the stopper, but since it is necessary to install a pressure receiving part (diaphragm) inside the stopper chamber, the structure is complicated and expensive, and furthermore, the water pressure gauge cannot be freely removed.
本考案は以上の点に鑑み、逆流防止機能が充分
で、かつ、水撃圧や脈動圧の緩和が可能であり、
取外しの自由な水圧計を有する止水栓を提供せん
とするものである。 In view of the above points, the present invention has a sufficient backflow prevention function and is capable of alleviating water hammer pressure and pulsating pressure.
It is an object of the present invention to provide a water stop valve having a freely removable water pressure gauge.

In the water stop valve of the present invention, when the stopper holder is positioned upward, the water pressure pushes up the check valve and the water flows from the inlet 3 through the water inlet 4 to the outlet 6.
flows to. Further, when the water is about to flow back, the non-return plug body is lowered by the elastic pressing force of the back surface, closes the water inlet 4, and prevents the water from flowing back. By rotating the stopper rod, the position of the stopper presser moves, the highest position of the stopper changes, and the flow rate at the water inlet can be adjusted. Further, the water inlet can be completely closed by lowering the stopper holder to its lowest position.

い。 The reverse stopper body has a cylindrical shape with a closed bottom end and is hollow inside. Water can flow in and out at a small flow rate between the stopper and the non-return stopper. For this reason, when in use, the inside of the non-return valve is always filled with water, and when the non-return valve moves up and down,
This water acts as a buffer material, slowing down the movement of the check valve. Therefore, even when water hammer pressure or pulsating pressure is applied from the primary side, the check valve body will not move suddenly in response, but will move slowly.
Water hammer pressure and pulsating pressure can be absorbed and alleviated, and there is no abnormal noise caused by the violent vibration of the check valve body.

An embodiment of the drawing of the stopcock of the present invention will be described. 1 is the stopper body, 2 is the packing box, and the inlet port 3
Water enters the tap chamber 5 through the water inlet 4,
It flows out from the outlet 6. A non-return stopper body 7 is attached to the stopper chamber 5 so as to be vertically movable. The reverse stopper body 7 has a cylindrical shape with a closed lower end surface, and is hollow inside. 8 is a gasket attached to the lower surface of the non-return stopper body 7. Reference numeral 9 denotes a stopper holder, which is screwed onto the stopper rod 10. Further, a push spring 11 is interposed between the stopper holder 9 and the non-return stopper 7, and a back elastic pressing force is always applied to the non-return stopper 7 in the closing direction. The inner wall of the seal box 2 serves as a sliding guide surface for the stopper holder 9, and a vertical groove 12 is formed in this inner wall, and a protrusion on the side surface of the stopper holder 9 is fitted into the vertical groove 12. The stopper presser 9 does not rotate and can only move in the vertical direction. Therefore, when the stopper rod 10 is rotated by the handle 13, the stopper presser 9 screwed onto the stopper rod 10 moves upward or downward. In addition, the vertical groove 12
also serves as a water passage hole when the non-return stopper body 7 moves up and down. That is, during use, water always fills inside the check valve body 7 through the vertical groove 12. When the non-return stopper body 7 moves up and down, water flows in and out through the vertical grooves 12. A buffer material 14 is attached to the lower surface of the flange portion of the stopper holder 9 to alleviate collisions with the non-return stopper 7. A through hole 15 is formed in the center of the plug rod 10, and a threaded portion 16 is provided at the upper end, into which a water pressure gauge 17 is screwed and fixed. The through hole 15 of the stopper rod 10 is connected to the through hole 18 of the water pressure gauge 17, so that the water pressure inside the stopper chamber 5 can be measured by the water pressure gauge 17.
When the water pressure gauge 17 is not used, a set screw 19 is attached to the threaded portion 16 as shown in FIG.
Further, an expansion joint 20 is attached to the outlet 6.

In the stop valve of the present invention, by rotating the stopper rod with the handle, the position of the stopper holder can be moved up and down.
It is possible to regulate the raised position of the non-return valve body, adjust the flow rate of water, and completely close the valve. Therefore, the flow rate can be adjusted according to the water pressure of the water main. In addition, since the back surface elastic pressing force is applied to the stopcock body, the backflow prevention function is reliable, and the backflow prevention function is not affected by the mounting angle of the stopcock. Furthermore, in the present invention, the non-return valve body is cylindrical with a closed bottom end, and when in use, the interior of the non-return valve body is filled with water, so when the non-return valve body is moved up and down, this water is becomes a buffer material. Therefore, water hammer pressure and pulsating pressure from the primary side can be absorbed and alleviated, and the non-return valve body does not undergo violent movement such as vibration, resulting in stable movement and no abnormal noise. Moreover, this makes it possible to prevent incorrect needles in the tap water dispenser connected and installed downstream of the water stop valve. Furthermore, since the present invention is equipped with a water pressure gauge, the water pressure inside the tap can be easily determined. Furthermore, since this water pressure gauge is removable, it can be removed when not needed, which is convenient. Furthermore, the hole in the stopper rod can also be used as an air vent hole, which is convenient for construction work.
