Description

Technical Field

[0001] The utility model relates to the technical field of flow regulating devices, and particularly relates to a flow regulating valve device suitable for narrow spaces. Background Art

[0002] Mechanical sludge removal refers to the method of removing sediment sludge in water purification structures by mechanical sludge suction or scraping. This method usually uses specially designed mechanical equipment to collect the sediment sludge in the structure and transports these sludges to a designated location through sludge discharge pipes for further treatment or discharge. During mechanical sludge removal, the sludge discharge pipe is an important part connecting the mechanical equipment and the discharge point.

[0003] Traditional sludge (sand) removal machines control the on-off and flow of sludge discharge pipes by using existing ball valves, butterfly valves, etc. on the market. The connection between the valve and the pipeline is usually pipe thread or flange connection. No matter which installation method is used, sufficient space is required, and it is not suitable for the situation where pipelines are densely arranged in narrow spaces. In addition, there are many various impurities in the medium of the pipeline of the sludge removal machine, which are easy to wind around the pump core, resulting in poor valve opening and closing. Therefore, it is necessary to design a flow regulating device that can be suitable for the situation where pipelines are densely arranged in narrow spaces. Content of the Utility Model

[0004] Aiming at the problem that the existing ball valves and butterfly valves are not suitable for narrow spaces with densely arranged pipelines, the utility model provides a flow regulating valve device suitable for narrow spaces. The utility model adapts to the situation of densely arranged pipelines in narrow spaces by changing the structure for controlling the opening of the control valve body. The flow regulating valve device described in the utility model adjusts the valve opening by controlling the relative position relationship between the adjusting rod and the connecting piece, occupies a small space and is convenient to use.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A flow regulating valve device suitable for narrow spaces includes a valve body, a valve seat, a connecting piece, and an adjusting rod. The valve seat is located in the sludge discharge tank and below the sludge discharge pipe; the cross-sectional area of the valve body gradually increases from the end close to the sludge discharge pipe to the end far from the sludge discharge pipe, and the diameter of the smallest end of the valve body is smaller than the diameter of the sludge discharge pipe orifice. The valve bodies equal in number to the sludge discharge pipes are fixed on the valve seat and their positions correspond to the positions of the sludge discharge pipes respectively; at least two adjusting rods are vertically installed on the valve seat, and several connecting pieces are slidably installed on the adjusting rods, and the connecting pieces are fixedly connected to the sludge discharge pipes.

[0007] Further, an external thread section is provided on the adjusting rod, and adjusting nuts are arranged on both the upper and lower sides of at least one connecting piece on each adjusting rod, and the adjusting nuts are threadedly connected to the external thread section.

[0008] Further, a plurality of pin holes are provided on the adjusting rod, and at least one connecting member on each adjusting rod is connected to the adjusting rod through a pin.

[0009] Further, the valve body is in a conical or frustum shape with the tip facing the sludge discharge pipe.

[0010] Further, the diameter of the largest end of the valve body is not less than the diameter of the orifice of the sludge discharge pipe.

[0011] Further, one adjusting rod is installed at each end of the valve seat.

[0012] The beneficial effects of the present utility model are as follows:

[0013] When the flow regulating valve device of the present utility model is provided on the sludge discharge pipe of the existing sludge scraper, the valve body is fixedly installed on the valve seat, and the position of the valve body corresponds to that of the sludge discharge pipe. Two adjusting rods are fixedly installed at both ends of the valve seat; the connecting member is fixedly installed on the sludge discharge pipe, and the adjusting rod is installed on the connecting member so that the connecting member can slide on the adjusting rod. The valve body is located below the sludge discharge pipe and corresponds to the position of the sludge discharge pipe. At this time, the installation of the flow regulating valve device is completed. The flow regulating valve device is simple to install and occupies a small space. By providing valve bodies with the same number as the sludge discharge pipes, it can be applied to the situation where pipelines are densely arranged in a narrow space and is convenient to use.

[0014] When it is necessary to open or close the valve, the relative position relationship between the valve body and the sludge discharge pipe is adjusted by adjusting the nut. When the valve body completely blocks the outlet of the sludge discharge pipe, the valve is in the closed state; when the valve body does not completely block the outlet of the sludge discharge pipe, the valve is in the open state. When the valve body extends into the outlet of the sludge discharge pipe, the degree of the valve body extending into the sludge discharge pipe can be adjusted to adjust the channel area at the outlet of the sludge discharge pipe, and thus the water discharge flow can be controlled, that is, the valve opening is adjusted.

[0015] In the present utility model, the valve body is located at the outlet of the sludge discharge pipe, and the impurities between the outlet of the sludge discharge pipe and the valve body are in a continuously scoured state, which is convenient for the impurities to be discharged from the outlet of the sludge discharge pipe. In addition, when the valve body does not extend into the outlet of the sludge discharge pipe, that is, when the valve on the sludge discharge pipe is completely open, the valve body will not affect the change of the diameter of the pipeline of the sludge discharge pipe itself, avoiding the influence of the change of the diameter after the valve is completely open on the fluid flow.

[0020] The following further details the present utility model in conjunction with the specific embodiments of the accompanying drawings, but the protection scope of the present utility model is not limited thereto.

[0021] Figures 1 - 3 This is a specific embodiment of the flow regulating valve device applicable to narrow spaces of the present utility model. The flow regulating valve device includes a valve body 3, a valve seat 4, a connecting piece 5, an adjusting rod 6, and an adjusting nut 7. The sludge discharge pipe 2 is arranged above the sludge discharge trough 1, and the sludge and sand in the sludge (sand) discharging machine can be discharged from the sludge discharge pipe 2 into the sludge discharge trough 1. The valve seat 4 is located in the sludge discharge trough 1 and below the sludge discharge pipe 2, and the valve seat 4 is used for installing the valve body 3. The cross-sectional area of the valve body 3 gradually increases from the end close to the sludge discharge pipe 2 to the end far from the sludge discharge pipe 2, and the diameter of the smallest end of the valve body 3 is smaller than the diameter of the pipe orifice of the sludge discharge pipe 2, so that the smallest end of the valve body 3 can extend into the sludge discharge pipe 2. When the valve body 3 extends into the outlet of the sludge discharge pipe 2, the channel area at the outlet of the sludge discharge pipe 2 decreases, and thus the water discharge flow can be controlled, that is, the valve opening can be controlled. The valve bodies 3 with the same number as the sludge discharge pipes 2 are fixed on the valve seat 4 and their positions correspond to the positions of the sludge discharge pipes 2 respectively. Even when the channel area decreases when extending into the outlet of the sludge discharge pipe 2, since the position of the valve body 3 corresponds to the position of the sludge discharge pipe 2, that is, located at the outlet of the sludge discharge pipe 2, the impurities between the outlet of the sludge discharge pipe and the valve body are in a continuously scoured state, which is convenient for the impurities to be discharged from the outlet of the sludge discharge pipe 2. In addition, when the valve body 3 does not extend into the outlet of the sludge discharge pipe 2, that is, when the valve on the sludge discharge pipe 2 is fully opened, the valve body 3 will not affect the change of the through diameter of the sludge discharge pipe 2 itself, avoiding the change of the through diameter of other valves even when fully opened due to the fact that the through diameter of the finished valves on the market is often smaller than the inner diameter of the equivalent pipes, and further avoiding the influence of the change of the through diameter after the valve is fully opened on the fluid flow. The valve body 3 is in a conical or frustum shape with the tip facing the sludge discharge pipe 2, and the diameter of the largest end of the valve body 3 is not less than the diameter of the pipe orifice of the sludge discharge pipe 2. When the valve body 3 continuously extends into the outlet of the sludge discharge pipe 2, the valve body 3 will completely block the outlet of the sludge discharge pipe 2, and at this time, it is equivalent to the valve being in a closed state.

[0022] The valve bodies 3 equal in number to the sludge discharge pipes 2 are fixed on the valve seat 4, and the relative position relationship between the valve body 3 and the sludge discharge pipe 2 can be adjusted by adjusting the position of the valve seat 4. At least two adjusting rods 6 are vertically installed on the valve seat 4. In this embodiment, two adjusting rods 6 are adopted, and one adjusting rod 6 is installed at each end of the valve seat 4. When the positions of the adjusting rods 6 at both ends of the valve seat 4 are adjusted, the position of the valve seat 4 can be driven to change, thereby adjusting the relative position relationship between the valve body 3 and the sludge discharge pipe 2. A number of connecting pieces 5 are slidably installed on the adjusting rods 6, and the connecting pieces 5 are fixedly connected to the sludge discharge pipes 2. Each adjusting rod 6 is provided with a connecting piece 5, and the connecting piece 5 and the adjusting rod 6 can slide relative to each other. For example, the connecting piece 5 is directly sleeved outside the adjusting rod 6, and at this time, the connecting piece 5 and the adjusting rod 6 can also slide relative to each other, and thus the relative position relationship between the valve body 3 and the sludge discharge pipe 2 can be adjusted by the position relationship between the connecting piece 5 and the adjusting rod 6. External thread sections are provided on the adjusting rods 6, and adjusting nuts 7 are provided on both the upper and lower sides of at least one connecting piece 5 on each adjusting rod 6 for limiting the connecting piece 5. The adjusting nuts 7 are threadedly connected to the external thread sections. When the adjusting nuts 7 on both the upper and lower sides of the connecting piece 5 are screwed, the position of the connecting piece 5 and the adjusting rod 6 can be adjusted. When the adjusting nuts 7 on all the adjusting rods 6 are screwed synchronously, the valve seat 4 can be controlled to move away from / towards the sludge discharge pipe 2 side, thereby driving the valve body 3 on the valve seat 4 to move away from / towards the sludge discharge pipe 2 side, that is, controlling the position relationship between the valve body 3 and the outlet of the sludge discharge pipe 2, and thus the opening and closing state of the valve can be controlled and the water discharge flow can be controlled when the valve is in the open state.

[0023] The way that the above-mentioned connecting piece 5 is slidably installed on the adjusting rod 6 can also be: a number of pin holes are provided on the adjusting rod 6, and at least one connecting piece 5 on each adjusting rod 6 is connected to the adjusting rod 6 through a pin, and the position relationship between the adjusting rod 6 and the connecting piece 5 is adjusted through the cooperation of the pin and the pin hole. Furthermore, the position relationship between the valve body 3 and the outlet of the sludge discharge pipe 2 can be adjusted by synchronously adjusting the position relationship between all the connecting pieces 5 and the adjusting rod 6, so as to control the opening and closing state of the valve and control the water discharge flow when the valve is in the open state.

[0024] Usage method: When installing the flow regulating valve device described in the present utility model on the sludge discharge pipe 2 of an existing sludge scraper, fix the valve body 3 to the valve seat 4, and make the position of the valve body 3 correspond to that of the sludge discharge pipe 2. Then, fix the two adjusting rods 6 to both ends of the valve seat 4. Fix the connecting piece 5 to the sludge discharge pipe 2, and install the adjusting rod 6 to the connecting piece 5 through the adjusting nut 7 or the pin, so that the valve body 3 is located below the sludge discharge pipe 2. At this time, the installation of the flow regulating valve device is completed. The flow regulating valve device is simple to install, occupies little space, and can be applied to the situation where pipelines are densely arranged in a narrow space, and is convenient to use. When it is necessary to open or close the valve, adjust the relative position relationship between the valve body 3 and the sludge discharge pipe 2 through the adjusting nut 7 or the pin. When the valve body 3 completely blocks the outlet of the sludge discharge pipe 2, the valve is in the closed state; when the valve body 3 does not completely block the outlet of the sludge discharge pipe 2, the valve is in the open state. When the valve body 3 extends into the outlet of the sludge discharge pipe 2, the channel area at the outlet of the sludge discharge pipe 2 can be adjusted by adjusting the degree to which the valve body 3 extends into the sludge discharge pipe 2, and thus the water discharge flow can be controlled.

[0025] The above examples are the preferred embodiments of the present utility model, but the present utility model is not limited to the above embodiments. Without departing from the essence of the present utility model, any obvious improvements, substitutions or variations that those skilled in the art can make all fall within the protection scope of the present utility model.
