Item 12, and an adjustment member 13. The valve seat 11 has an inflow passage 111, a first outflow passage 112, and a restriction hole 113 located between the inflow passage 111 and the outflow passage 112. The adjusting member 13 has a notch 131. When the adjusting member 13 enters the pressure bottle 10, the cleaning liquid in the pressure bottle 10 flows out through the notch 131 of the adjusting member 13, and flows out to the outflow channel 112 through the restriction hole 113. Thereby, the flow of the cleaning liquid in the pressure bottle 10 into the outflow channel 112 is restricted through the restricting hole 113 to prevent all the cleaning liquid entering the inflow channel 112 from flowing out of the outflow channel 112 to avoid stopping the engine when it stops. Operational.

However, because the size of the restriction hole 113 is fixed, the flow output from the output channel 112 is also fixed. Therefore, if the valve body of a large-displacement engine (such as a heavy-duty locomotive) is used in When the engine with small displacement (such as light locomotive), the engine with smaller displacement will still stop and stop running. Conversely, if the switching valve body suitable for an engine with a small displacement is applied to an engine with a large displacement, the cleaning efficiency is not good because the flow rate is too small.

Therefore, an object of the present invention is to provide an on-off valve device capable of adjusting a flow rate.

Therefore, the new on-off valve device is suitable for connecting a pressure bottle. The pressure bottle includes a pressure chamber for holding a fluid, an opening communicating with the pressure chamber and outputting the fluid, and a neck surrounding the opening. unit. The on-off valve device includes a fixed seat and an adjustment unit.

At the blocking position, the shoulder surface is close to the inner wall surface, and the adjusting member blocks the The inflow channel is in communication with the flow volume chamber. At the maximum communication position, the shoulder surface is away from the inner wall surface. The inflow channel and the flow volume chamber communicate with each other so that the fluid flows out of the flow volume chamber and from the outflow. The channel outputs, and the flow rate of the fluid output from the outflow channel increases as the distance between the shoulder surface and the inner wall surface increases.

The effect of the novel model is that by providing the adjustment member, not only can the inflow channel be passed in and out through the adjustment member to block or not block the communication between the inflow channel and the flow volume chamber, but also the adjustment member can pass through the axis The direction of movement changes the length of one end of the adjusting member from the inner wall surface, thereby adjusting the flow rate of the fluid output by the outflow channel to achieve the effect of adjusting the flow rate.

Referring to FIG. 2, FIG. 3 and FIG. 4, an embodiment of the novel switching valve device is suitable for connecting a pressure bottle 5. The pressure bottle 5 includes a pressure container 51 for containing a fluid, an opening 52 communicating with the pressure container 51 and outputting the fluid, and a neck 53 surrounding the opening 52.

The on-off valve device includes a fixed seat 2, an adjustment unit 3, and a washer 4.

The fixed seat 2 extends along an axis X and is detachably mounted on the pressure bottle 5 and includes a body 21 and an inflow channel 22 defined by the seat body 21 and communicating with the opening 52. An outflow channel 23 for outputting the fluid, a flow volume chamber 24 connecting the inflow channel 22 and the outflow channel 23, an inflow port 25 located at the boundary of the flow volume chamber 24 and the inflow channel 22, and extending along the axis X The mounting hole 26 communicates with the inflow passage 22 and an adjustment hole 27 extending along the axis X direction and communicating with the flow volume chamber 24.

The seat body 21 has an inner wall surface 211 defined at the bottom of the flow volume chamber 24 and forming the inflow port 25, and a thread is formed on a peripheral surface defining the mounting hole 26 to be suitable for screwing the pressure bottle 5, and the The seat body 21 is threaded on a peripheral surface defining the adjustment hole 27.

The adjusting unit 3 includes an adjusting group 31 that can be moved along the X direction of the axis, and a knob 32 connected to the adjusting group 31.

The adjusting group 31 includes an adjusting member 311 that can move along the X direction of the axis, and a drainage tube 312 passing through the opening 52 and the inflow channel 22.

The adjusting member 311 has a main body section 313 extending along the axis X direction, a blocking section 314 extending from the main body section 313 along the axis X direction and having an outer diameter tapering away from the main body section, and a boundary defined in A shoulder surface 315 at the junction of the main body section 313 and the blocking section 314.

A thread is formed on the outer surface of the main body section 313 for being screwed in the adjusting hole 27 and passing through the flow volume chamber 24.

The maximum outer diameter of the blocking section 314 is smaller than the maximum outer diameter of the main body section 313.

Referring to FIGS. 4 and 5, the adjusting member 311 is movable relative to the inner wall surface 211 between a blocking position (as shown in FIG. 4) and a maximum communication position (as shown in FIG. 5). In the position, when the shoulder surface 315 is close to the inner wall surface 211, and the blocking section 314 blocks the communication between the inflow channel 22 and the flow volume chamber 24, when the adjusting member 311 is at the maximum communication position, the shoulder surface When 315 is far away from the inner wall surface 211, the inflow channel 22 and the flow volume chamber 24 communicate with each other, so that the fluid flows out to the flow volume chamber 24, and is output from the outflow channel 23, and the outflow channel 23 outputs the fluid. The flow rate increases as the distance between the shoulder surface 315 and the inner wall surface 211 increases.

The drainage tube 312 has a notch 316 extending along the X direction of the axis. The notch 316 is suitable for the fluid to flow out, so that the fluid passes from the pressure chamber 51 into the inflow passage 22 through the notch 316. In this embodiment, the notch 316 extends from one end surface of the adjusting member 311 along the axis X direction to the other end surface. In other variations of this embodiment, the notch 316 may also be adjacent to the One end surface of the flow volume chamber 24 extends along the axis X in a direction opposite to the flow volume chamber 24. Similarly, the fluid can also pass from the pressure volume chamber 51 through the gap 316 into the inflow passage 22.

The knob 32 is connected to the main body section 313 of the adjusting member 311 and drives the adjusting member 313 to move along the axis X direction when rotating.

It is worth noting that, in this embodiment, the drainage pipe 312, the adjusting member 311, the flow volume chamber 24, and the inflow channel 22 are all located on the axis X. In other variations of this embodiment, the flow rate The accommodating chamber 24 and the inflow channel 22 may also be located on different lines from the drainage tube 312 and the adjusting member 311, as long as the adjusting member 311 can block or not block the communication between the flow accommodating chamber 24 and the inflow channel 22 In addition, the volume of the flow volume chamber 24 can be changed according to the position of the adjusting member 311 to achieve the effect of the embodiment.

In addition, in this embodiment, the inflow port 25 is closed by a blocking section 314 having a larger outer diameter so that the flow volume chamber 24 and the inflow channel 22 are not connected. In other variations of this embodiment, The shoulder surface 315 can also be abutted against the inner wall surface 211 to make the inflow passage 22 and the flow volume chamber 24 not communicate with each other.

The washer 4 surrounds the washer 4 provided outside the fixing seat 2, and when the fixing seat 2 is installed on the pressure bottle 5, the washer 4 is located between the mounting seat and the neck 53 of the pressure bottle 5. It is worth noting that when the fixing seat 2 is installed on the pressure bottle 5, the fluid will escape to the outside through the drainage tube 312 entering the pressure container 51, so the fixing can be increased by providing the gasket 4. The tightness between the seat 2 and the pressure bottle 5 prevents the fluid from escaping from the gap between the neck 53 of the pressure bottle 5 and the fixed seat 2.

When installing, it is only necessary to first align the mounting hole 26 with the opening 52 of the pressure bottle 5 and set the screw surrounding the mounting hole 26 in the pressure bottle 5 to complete the installation. At this time, the fluid located in the pressure chamber 51 will enter the drainage tube 312 through the opening 52 due to the pressure difference, and accumulate in the inflow channel 22 through the notch 316 of the drainage tube 312, and pass through the adjusting member 311. The larger outer diameter portion of the blocking section 314 closes the inflow port 25.

It is worth noting that the directions of rotation described in the following usage modes are described with common right-handed spirals, and the embodiments of the present invention are not limited to the directions of rotation described below.

Referring to FIGS. 5 and 6, when in use, it is only necessary to rotate the knob 32 counterclockwise, so that the knob 32 drives the adjusting member 311 to move upward along the axis X direction, so that the smaller outer diameter portion of the blocking section 314 is located in the The inflow opening 25 is not closed, so that the fluid can enter the flow volume chamber 24 through the inflow opening 25. If a smaller flow rate is required (as shown in Figure 5), simply turn the knob 32 clockwise to drive the adjusting member 311, so that the shoulder surface 315 is close to the inner wall surface 211, so that the shoulder surface 315 and the inner wall surface The distance between 211 is reduced, so that the larger outer diameter portion of the blocking section 314 reduces the width of the inflow port 25, thereby reducing the flow rate of the fluid output from the outflow channel 23. Similarly, if a larger flow rate is required (as shown in FIG. 6), simply turning the knob 32 counterclockwise will cause the adjustment member 311 to move upward, so that the length between the shoulder surface 315 and the inner wall surface 211 increases. The portion with the smaller outer diameter of the blocking section 314 increases the width of the inflow port 25, thereby increasing the flow rate of the fluid output from the outflow channel 23.

Referring to FIG. 4, if the fluid is not required to be output after being used, turning the knob 32 clockwise drives the adjusting member 311 downward to approach the inflow channel 22, and the outer diameter of the blocking section 314 to the adjusting member 311 is larger Partially closing the inflow port 25 can block the communication between the inflow passage 22 and the flow volume chamber 24, so that the fluid can no longer be output.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. By setting the adjusting member 311, not only can the inflow channel 22 be passed through the adjusting member 311 to block or not block the communication between the inflow channel 22 and the flow volume chamber 24, but also the adjusting member 311 can be borrowed. The length of the shoulder surface 315 from the inner wall surface 211 is changed by the movement in the X direction of the axis, thereby adjusting the flow rate of the fluid output by the outflow channel 23 to achieve the effect of adjusting the flow rate.

2. The closeness between the switching valve device and the pressure bottle 5 is increased by providing the gasket 4 to prevent the fluid from flowing from the neck 53 and the neck of the pressure bottle 5 when the switching valve body is installed on the pressure bottle 5. The gap between the fixing bases 2 escapes.

In summary, the new on-off valve device can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
