Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a new valve which is convenient for adjusting flow rate. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0003] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In pipeline transportation, the requirements for flow rate and flow are different. Sometimes a high flow rate is required to meet the transportation requirements, and sometimes a low flow rate is required for convenient control.

[0004] Therefore, a new valve which is convenient for adjusting flow rate is proposed. Summary of the invention

[0011] Furthermore, a large integrally formed connecting ear is provided on one side of the valve body close to the water outlet pipe.

[0012] Furthermore, the large connecting ear is hinged to the lower pressure rod through a pin, so that the lower pressure rod can be rotated and displaced to facilitate downward movement.

[0015] Furthermore, the push-down rod is provided with a slide groove cooperating with the slider to slide, so that the slider can slide smoothly in the slide groove, which is convenient for use with the electric push rod to drive the push-down rod to move downward.

[0016] Furthermore, the end of the switch rod that contacts the push-down rod is arc-shaped, and the smooth arc-shaped design can reduce friction with the push-down rod and increase the service life of the push-down rod.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-2 , the utility model provides a technical solution:

[0029] A new type of valve for adjusting flow rate, comprising a valve body 1 and a push rod 4, wherein an integrally formed water inlet pipe 2 is installed on one side of the valve body 1 to facilitate the flow of objects, and an integrally formed water outlet pipe 9 is installed on the other side to facilitate the flow, one end of the push rod 4 is hinged to the side of the valve body 1 close to the water outlet pipe 9, so that the push rod 4 can be rotated downward, which is convenient for controlling the switch of the valve flow rate, in order to automatically control the downward pressure of the push rod 4, a driving device is installed at the top of the water inlet pipe 2, and a movable block hinged to the drive device is installed at the output end of the drive device, so that the movable block is slidably connected to the push rod 4, and the movement of the push rod 4 is controlled by the driving device A convex cavity 11 is opened inside the valve body 1. In order to facilitate circulation, the convex cavity 11 is connected with the water inlet pipe 2 and the water outlet pipe 9 respectively. The switch rod 7 is installed inside the convex cavity 11, so that the top end of the switch rod 7 extends to the outside of the valve body 1 and contacts the down-pressing rod 4. When the down-pressing rod 4 is pressed down, the switch rod 7 is driven to move downward. In order to control the flow rate or the opening and closing of the valve, a blocking block 71 is set at the bottom end of the down-pressing rod 4, so that the blocking block 71 is tightly fitted at the connection between the wide and narrow spaces of the convex cavity 11. At the same time, a rebound structure is set at the bottom end of the blocking block 71, so that when the down-pressing rod 4 is lifted, it is convenient to drive the blocking block 71 to reset upward.

[0030] like Figure 1 As shown:

[0031] An integrally formed large connecting ear 8 is provided on one side of the valve body 1 close to the water outlet pipe 9, and the large connecting ear 8 is hinged to the pressing rod 4 through a pin shaft to realize the rotation and pressing down of the pressing rod 4, so as to facilitate the rotation around the large connecting ear 8 as the center.

[0032] like Figure 1 As shown:

[0033] The driving device is an electric push rod 3, and the movable block is composed of a small connecting ear 6 and a slider 61. The small connecting ear 6 and the slider 61 are integrally formed, so that the output end of the electric push rod 3 is hinged to the small connecting ear 6 through a pin shaft, and the lower pressure rod 4 is provided with a slide groove 41 that slides with the slider 61. Since it is hinged to the small connecting ear 6, the electric push rod 3 can drive the lower pressure rod 4 to move downward. Since the slider 61 slides with the slide groove, the range by which the electric push rod 3 can drive the lower pressure rod 4 to move downward can be expanded, so that the size of the gap at the connection between the blocking block 71 and the wide and narrow space of the convex cavity 11 is conveniently adjusted, which is more conducive to controlling the flow rate. At the same time, a slope is set on the blocking block 71, and an inclined surface that fits closely with the slope is set at the connection between the wide and narrow spaces of the convex cavity 11, so that it is tighter when closed.

[0034] like Figure 1 As shown:

[0035] The end of the switch rod 7 that contacts the pressing rod 4 is arc-shaped, and the smooth arc-shaped design can reduce the wear on the pressing rod 4 and increase the service life.

[0036] like Figure 1 As shown:

[0037] The rebound structure is a spring 10 , which facilitates the upward and downward rebound reset of the blocking block 71 and the switch rod 7 .

[0038] Working principle:

[0039] The output end of the electric push rod 3 drives the pressing rod 4 to press down, so that the switch rod 7 moves downward. At this time, the slope of the blocking block 7 is separated from the inclined surface at the connection between the wide and narrow spaces of the convex cavity 11, and a gap is exposed to facilitate fluid circulation. In this process, the larger the gap exposed, the faster the flow rate, and vice versa. When the gap is completely closed, the valve is in a closed state as a whole.

[0040] When the valve is in a closed state as a whole, the switch rod 7 loses pressure, and the spring 10 drives the blocking block 71 and the switch rod 7 to reset, completely closing the gap.

[0041] Embodiment 2:

[0042] The difference from the first embodiment is that a ball head 5 which is easy to hold is provided on the pressing rod 4, and the design of the driving structure is cancelled. The pressing rod 4 is pressed down manually by the ball head 5, so that the flow rate is manually controlled.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
