Abstract
Description
Technical Field
[0001] The present application relates to a valve structure, and in particular to an adjustable orifice valve. Background Art
[0002] Generally, the throttling orifice valve installed in the pipeline is connected to the pipeline through two flanges. The size of the throttling hole is fixed, and the throttling hole must be smaller than the inner diameter of the pipeline to play a throttling role. However, when it is needed on site, the flow rate cannot be adjusted by adjusting the size of the hole. Utility Model Content
[0003] The utility model aims to provide an adjustable orifice valve to achieve flow control.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.
[0005] An embodiment of the present application discloses an adjustable orifice valve, including a valve body sealed and installed between a first flange and a second flange, a horizontal flow channel being formed inside the valve body, a gear ring being arranged on the horizontal flow channel near the second flange, the horizontal flow channel passing through an axial hole of the gear ring, the outer side of the gear ring being meshed with a horizontal gear shaft, the horizontal gear shaft sealing protruding to the outer side of the valve body, a lever fork being formed on the outer side of the horizontal gear shaft, a lever being inserted into the lever fork, a limiting flow plate being formed on one side of the gear ring, an adjustment seat being sealably arranged on the right side of the limiting flow plate, a water flow hole being formed on the surface of the adjustment seat, and when the gear ring rotates, the limiting flow plate blocks part / all of the water flow hole.
[0006] Preferably, in the above-mentioned adjustable orifice valve, the flow limiting plate is fan-shaped.
[0007] Preferably, in the above-mentioned adjustable orifice valve, a sealing ring is provided between the horizontal gear shaft and the valve body.
[0008] Preferably, in the above-mentioned adjustable orifice valve, the horizontal gear shaft is provided with a fixing nut on the outer side of the valve body.
[0009] Compared with the prior art, the advantages of this technical solution are that the valve body and the adjusting seat are fixed together by bolts, the gear shaft is connected to the standard rod and is connected to the valve body and the adjusting seat by threads, fixed with a nut, with an O-ring inside, and the inside of the gear shaft is meshed with the gear ring. When working, the standard rod is rotated to drive the gear shaft, and the gear shaft and the gear ring are meshed to move in the opposite direction, thereby realizing flow control. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0011] Figure 1 FIG. 1 is a schematic diagram of an adjustable orifice valve in an embodiment of the utility model.
[0012] Figure 2 Shown is a cross-sectional view of an adjustable orifice valve in an embodiment of the utility model. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] Combination Figure 1-2 As shown, the adjustable orifice valve 100 includes a valve body 103 sealed and installed between a first flange 101 and a second flange 102, a horizontal flow channel 104 is formed inside the valve body 103, a gear ring 105 is arranged near the second flange 102, the horizontal flow channel 104 passes through the axial hole of the gear ring 105, the outer side of the gear ring 105 is meshed with a horizontal gear shaft 106, the horizontal gear shaft 106 seals and protrudes to the outer side of the valve body 103, a lever fork 107 is formed outside the horizontal gear shaft 106, a lever 108 is inserted into the lever fork 107, a limiting plate 109 is formed on one side of the gear ring 105, an adjustment seat 110 is sealed and arranged on the right side of the limiting plate 109, a water flow hole 111 is formed on the surface of the adjustment seat 110, and when the gear ring 105 rotates, the limiting plate 109 blocks part of / all of the water flow holes 111. The limiting plate 109 is fan-shaped. A sealing ring 112 is disposed between the horizontal gear shaft 106 and the valve body 103. A fixing nut 113 is disposed on the outer side of the valve body 103 of the horizontal gear shaft 106.
