Description

Improved structure of pressure reducing valve group (2)

The present invention relates to an improved structure (2) of a pressure reducing valve group, and particularly relates to a method for reducing water pressure and maintaining fluid pressure to a stable value, and can be combined with different construction occasions to form a leftward or rightward rotation. Improved structure of the closed-pressure reducing valve group.

According to the general urban one-way water supply pipeline, the upstream (inlet) pressure of the higher valve can be reduced to the downstream (outlet) pressure that meets the requirements of use. Usually, the pressure reducing valve is installed on the one-way water supply pipeline, regardless of the upstream pressure and flow. How to change, the adjusted downstream pressure is kept constant by the pressure reducing valve. When the main valve is opened, the medium flows to the outlet and also passes through the pressure reducing valve, so that the outlet of the pressure reducing valve is highly stable at a certain value. This way the pressure behind the valve can be constant. In order to be able to cooperate with the use of the pressure reducing valve, it is necessary to install a ball valve at the inlet and outlet for controlling the inlet and outlet. The conventional ball valve is provided with a hole with a hole inside, and the handle of the ball can be used as a handle. When the sphere is rotated 90 ,, all the spheres should be present at the inlet and outlet to intercept the flow. When the sphere is turned back, the hole on the sphere is parallel to the axis of the valve to form a channel. However, the handle of the conventional ball valve can only be rotated 90 ∘, that is, it can only be rotated in one direction. Therefore, when the installed position cannot rotate in this direction (such as when it is close to the wall), the construction will be formed. Troubled on. In view of this, the applicant has continuously researched and experimented, and Meng Mengsheng designed an improved structure (2) of the pressure reducing valve group, which can be closed with different construction occasions, and can be closed in the left or right direction.

The main purpose of the present invention is to provide an improved structure (2) of a pressure reducing valve group for maintaining a constant pressure of the fluid pressure, and for different construction occasions, to constitute a leftward or rightward rotation.

The improved structure (2) of the pressure reducing valve group described above includes a pressure reducing valve and at least two ball valves connected to the pressure reducing valve. Wherein, the pressure reducing valve is provided with a body composed of an upper cover and a lower cover and a seat bottom, and the lower cover is provided with a water inlet passage and a water outlet passage for maintaining the fluid pressure to a stable value to adjust the outlet side pressure The ball valve is connected to the water inlet passage and the water outlet passage of the pressure reducing valve, and is provided with a body, a handle having a top portion is disposed on the body, and a stop portion corresponding to the top portion is disposed at an appropriate position .球 The ball valve is opened or closed by the rotation of the handle, and the handle can be rotated by 180 藉 by the limit of the holding portion of the stopping portion, so that the pressure reducing valve group can be matched with different construction occasions. It can be turned off in the left or right direction.

The improved structure (2) of the pressure reducing valve group described above, wherein the ball valve is provided with a bypass pipe for installing a pressure gauge on the bypass pipe, thereby providing a pressure value for monitoring the fluid.

In the above modified structure of the pressure reducing valve group (2), a Y-type filter is connected between the pressure reducing valve and one of the ball valves for constituting the function of filtering impurities.

Please also refer to Figure 1 and Figure 2 for a perspective view of the creation and a top view of the ball valve. As shown, the present invention includes a pressure reducing valve 1 and at least two ball valves 2 connected to the pressure reducing valve 1. The pressure reducing valve 1 is provided with a body 1 composed of an upper cover 11 and a lower cover 12 and a base 13. The lower cover 12 is provided with a water inlet passage 121 and a water outlet passage 122, and a spring seat is disposed inside the body. , a spring, a diaphragm, a shaft and a water stop and other components. Thus, the actuating element of the pressure reducing valve can be used to adjust the flow rate of the fluid. When the fluid pressure at the outlet end is lowered, the components inside the body are synchronously displaced downward, thereby increasing the opening distance of the water inlet opening of the lower cover. The fluid pressure flowing in the direction of the water outlet channel is also increased because the opening distance becomes larger; and when the fluid pressure at the outlet end is increased, the components inside the body body are synchronously displaced upward, and the lower cover water inlet channel is discharged. The opening distance of the nozzle becomes smaller, and the fluid pressure flowing in the direction of the outlet passage is also reduced because the opening distance becomes smaller, so that the fluid pressure can be maintained at a stable value to adjust the pressure on the outlet side for maintaining the fluid pressure. A stable value to achieve adjustment of the outlet side pressure.

The ball valve 2 is connected to the water inlet passage 121 and the water outlet passage 122 of the pressure reducing valve 1 , and is provided with a body 21 . The body 21 is internally provided with a hole with a hole, so that the ball body is pivotally connected to a through hole 22 . The rotating shaft 23 is provided with a handle 24 at the top end of the rotating shaft 23. The rotation of the handle 24 makes the hole in the sphere parallel to the inlet and outlet ports to form a passage to open, or the water inlet and the outlet are blocked by the ball. The break constitutes closed. The handle 24 is provided with a top portion 241 at the end, and a rod-shaped stopper portion 25 is respectively disposed on both sides of the sleeve hole 22. The ball valve is opened or closed by the rotation of the handle 24, and the handle 24 can be rotated by 180 turns by the limit of the stopper portion 25. The ball valves 2 are provided with a bypass pipe 26 at an appropriate position for the pressure gauge to be installed in the bypass pipe 26 for monitoring the pressure value of the fluid.

A Y-type filter 3 is connected between the pressure reducing valve 1 and one of the ball valves 2.

An improved structure of a pressure reducing valve group is constructed by the combination of the foregoing members. For the installation of the one-way water supply pipe, the pressure reducing valve 1 is used to maintain the fluid pressure as a stable value to adjust the outlet side pressure, and the ball valve 2 on both sides controls the opening and closing of the fluid. Wherein, when the present invention is installed in an environment in which the handle 24 of the ball valve 2 cannot be unidirectionally rotated, since the handle 24 is in a state of being able to rotate 180 degrees, the handle 24 can be left without being affected by the construction environment. Rotate or turn right, so that the pressure reducing valve group can be matched with different construction occasions. The Y-type filter 3 connected between the pressure reducing valve 1 and one of the ball valves 2 can filter impurities and protect the life of the pressure reducing valve 1 from increasing.

Please refer to Figure 3, which is a state diagram of the installation of this creation. As shown in the figure, when the creation is in the assembly, when the environment to be applied is close to the wall surface (as in this embodiment, the pressure reducing valve group is respectively installed on both sides of one wall 4), the general ball valve The pressure reducing valve group formed by the handle can only be opened and closed by one-way rotation, which will cause construction problems, that is, one group of pressure reducing valve groups cannot be so close to the wall 4, Due to the construction environment, the operators are bound to find other solutions, which not only consumes time and labor, but also affects the efficiency of the operation.

Figure 4 is a diagram showing the state of the opening and closing of the creation. As shown in the figure, when the two sets of pressure reducing valve groups are installed on both sides of the wall 4 in response to the construction environment, the pressure reducing valve group is closely attached to the wall 4, and the general ball valve is formed. The pressure reducing valve group, because the handle can only be turned on and off for one-way rotation, will cause construction problems. Since the handle 24 is in a state of 180° rotation, the handle 24 can be rotated left or right without being affected by the construction environment. As in this embodiment, the handles of the two groups of pressure reducing valve groups 24, can be left or right, respectively, so that the pressure reducing valve group can be matched with different construction occasions.

The foregoing embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and the details of the present invention are not deviated from the spirit of the present invention.

In summary, the present invention constitutes an improved structure of the pressure reducing valve group by using a pressure reducing valve and at least two ball valves connected to the pressure reducing valve, a handle provided on the ball valve, and a stopper corresponding to the handle. In order to maintain the fluid pressure as a stable value, and can be combined with different construction occasions or environments, the left or right rotation start and close control is formed. For a practical design, it is a novelty creation.
