Description

Technical Field

[0001] The utility model relates to the technical field related to valves, in particular to a ball valve with adjustable delivery volume. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] For example, the patent document with application number 202222691257.9 discloses an adjustable ball valve. The utility model provides an adjustable ball valve, including a ball valve, flanges are fixedly connected to both ends of the ball valve, a sealing mechanism is provided on one side surface of the flange, a valve ball is installed inside the ball valve, a fixing block is welded on the upper surface of the ball valve, and a speed regulating mechanism is provided on the surface of the fixing block. The adjustable ball valve is configured with a dial, a limit groove, a limit block, a hand wheel and a ruler. When in use, the dial is first pressed down, and the dial squeezes the limit block. Then, the dial is pressed down further. When the dial is pressed to the bottom, the limit block enters the limit groove. At the same time, due to the special shape of the limit block, the dial can no longer be moved. When the hand wheel is turned to adjust the flow rate of the liquid in the ball valve, the cross-sectional area through which the fluid in the ball valve can pass can be obtained according to the position of the ruler relative to the dial, thereby achieving the effect of more accurately adjusting the flow rate of the liquid in the ball valve. However, after the adjustable ball valve is adjusted for flow, if it is accidentally touched, it will cause the scale to shift, affecting the accuracy of flow control.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a ball valve with adjustable delivery volume is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] like Figure 1-Figure 3 As shown, a ball valve with adjustable delivery volume includes a ball valve flow control device body 1, a damping bearing 204 is fixedly installed on the surface of the ball valve flow control device body 1, and a ball valve rotating device 202 is rotatably installed on the inner wall of the damping bearing 204, and the ball valve rotating device 202 is composed of a rotating rod and a ball valve. The advantage of this arrangement is that this arrangement is not redundant for existing devices.

[0021] Furthermore, a circular holder 205 is installed at the upper end of the ball valve rotating device 202, and a compression device 203 with a rotating bearing is installed on the inner wall of the circular holder 205, and the compression device 203 is composed of a sleeve, a compression spring and a limit rod. The advantage of this arrangement is that, through the arrangement of the circular holder 205, the compression device 203 can be pressed down by rotating the plug block 201 to engage with the circular holder 205, and then the ball valve rotating device 202 can be adjusted through the damping bearing 204 to adjust the flow rate. While ensuring accurate flow regulation, it can avoid accidental touch causing the ball valve rotating device 202 to rotate, thereby affecting the accuracy of the ball valve in controlling the flow rate.

[0022] Furthermore, a rotating plug block 201 is provided at the upper end of the compression device 203, and a rotating cover 2 is installed at the upper end of the rotating plug block 201, and the rotating plug block 201 is connected to the circular seat 205 by plugging. The advantage of this arrangement is that, through the arrangement of the rotating cover 2, it is convenient to press down the rotating plug block 201 to adjust the ball valve.

[0023] Furthermore, a scale plate 101 is installed at the upper end of the main body 1 of the ball valve flow control device, and the rotating cover 2 is arranged inside the scale plate 101. This arrangement is an existing device and will not be described in detail.

[0024] like Figure 4As shown, guide rails 302 are provided on both side surfaces of the main body 1 of the ball valve flow control device, and a protective shell 303 is slidably installed on the surface of the guide rails 302, an observation window 304 is provided on the surface of the protective shell 303, and a shift block 305 is provided on the front end of the surface driven by the observation window 304. The advantage of this arrangement is that the adjustment device can be protected by the arrangement of the protective shell 303, and the dial 101 can also be observed through the observation window 304.

[0025] Furthermore, a fixed baffle 3 is installed at the front end of the ball valve flow control device body 1, and magnetic blocks 301 are installed on both sides of the fixed baffle 3. The advantage of this arrangement is that the ball valve flow control device can be sealed by the arrangement of the fixed baffle 3 and the magnetic block 301 to prevent dust from falling into the interior of the circular clamping seat 205 and accelerating aging and damage of the ball valve flow control device.

[0026] Working principle: When using the ball valve with adjustable delivery volume, first, press down the rotating cover 2 to drive the rotating plug 201 to press down the compression device 203 and engage with the circular card seat 205, and then rotate the ball valve rotating device 202 to adjust the flow through the damping bearing 204. If the rotating plug 201 does not contact the circular card seat 205, the rotating plug 201 will only idle along the rotating shaft on the surface of the compression device 203 to avoid accidental contact causing the ball valve rotating device 202 to rotate, affecting the accuracy of the ball valve to control the flow. After the flow is adjusted, the protective shell 303 is slid into the upper end of the ball valve flow control device body 1 through the guide rail 302, and the protective shell 303 is contacted with the fixed baffle 3 through the dial block 305, and the magnetic suction block 301 adsorbs the protective shell 303 to complete the fixation. This is the working principle of the ball valve with adjustable delivery volume.
