Valve body capable of adjusting flow

Abstract

The utility model discloses a valve body capable of adjusting flow, which belongs to the technical field of valve bodies and comprises a valve body, an air cylinder is fixedly arranged on one side of the valve body, a connecting block is fixedly connected to one end of the air cylinder, an ejector pin is fixedly connected to one side of the connecting block, and a valve hole is arranged in the valve body. According to the utility model, when the ejector pin and the valve hole keep a smaller circulation gap through stretching and retracting, gas entering the valve body from the gas inlet pipe firstly contacts with the flow turbine and drives the flow turbine to rotate, and in the process, gas materials entering the valve body from the gas inlet pipe collide with each other and rotate due to the flow turbine, so that the gas materials enter the valve body from the gas inlet pipe; when the ejector pin stretches out and draws back, flowing gas can be slowed down to a certain degree, the speed of the gas entering the valve hole can be slowed down, then the flowing speed of the gap between the ejector pin and the valve hole cannot be suddenly increased, and therefore the accuracy of the ejector pin stretching out and drawing back to adjust the flow is guaranteed.

Description

Technical Field

[0001] The utility model belongs to the technical field of valve bodies, and in particular relates to a valve body capable of adjusting flow. Background Art

[0002] When a traditional flow valve body uses a valve needle to adjust the flow, different degrees of closing of the valve needle will achieve different flow closing effects. When the closing gap between the valve needle and the valve hole is small, at the same delivery flow of the delivery pipe, the delivery speed of the gap between the valve needle and the valve hole will become larger. In this way, when the valve needle is adjusted from time to time, due to the difference in speed change of the front and rear valve hole gaps, the total flow rate flowing inside the front and rear valve hole gaps of different sizes adjusted front and rear will not be much different within a certain period of time, which is not conducive to precise flow regulation of the valve hole. Therefore, a valve body with adjustable flow is needed to solve the above problem. Utility Model Content

[0003] The purpose of the utility model is to provide a valve body capable of adjusting flow rate, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a flow-adjustable valve body comprises a valve body, a cylinder is fixedly arranged on one side of the valve body, one end of the cylinder is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to a ejector pin, a valve hole is arranged inside the valve body, the ejector pin is located in the valve hole, and the diameter of the ejector pin tends to be larger and smaller from left to right, the valve body is slidably connected with a connecting block through a sliding bar, a fixing ring block is fixedly connected to the upper surface of the connecting block, the telescopic section of the cylinder passes through the interior of the fixing ring block, a flow turbine is rotatably connected to the fixing ring block, a sliding rod is slidably connected to the interior of the fixing ring block, one end of the sliding rod is fixedly connected to one side of the connecting block, one end of the sliding rod is fixedly connected to a first limit block, the outside of the sliding rod is fixedly connected to a second limit block, and an intake pipe is connected to the valve body.

[0005] By setting the above structure, the cylinder will drive the ejector pin to be inserted into the valve hole when it is working. During this period, due to the different diameters of various parts of the ejector pin, the ejector pin can achieve different degrees of blocking of the valve hole, thereby achieving flow regulation in the valve hole. When the ejector pin maintains a small flow gap with the valve hole through expansion and contraction, the gas entering the valve body from the intake pipe will first contact the flow turbine and drive the flow turbine to rotate. In this process, the collision and rotation of the flow turbine on the gas material entering the intake pipe will help to decelerate the circulating gas to a certain extent, so that the gas entering the valve body can slow down the speed of entering the valve hole, and then the flow speed of the gap between the ejector pin and the valve hole will not be suddenly accelerated, thereby helping to ensure the accuracy of the flow regulation by the expansion and contraction of the ejector pin.

[0006] As a preferred embodiment, the air intake pipe is located above the flow turbine.

[0007] As a preferred implementation, one side of the valve body is connected to a connecting pipe via a connecting piece.

[0008] As a preferred implementation, a pressure sensor is provided on the connecting pipe.

[0009] As a preferred implementation, a pressure display is fixedly provided on the connecting pipe.

[0010] As a preferred implementation, the pressure sensor is connected to a pressure display.

[0011] By setting up a pressure sensor and a pressure display, the gas flowing through the valve hole will flow into the connecting pipe. When the gas flows through the connecting pipe, the pressure sensor will detect the pressure of the gas and display it in real time through the pressure display, so that manual adjustments can be made according to the displayed data on the pressure display.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model, by arranging an air cylinder, can drive the ejector pin to be inserted into the valve hole when the air cylinder is working. During this period, due to the characteristics of different diameters of various parts of the ejector pin, the ejector pin can achieve different degrees of blocking of the valve hole, thereby realizing flow regulation of the flow in the valve hole. When the ejector pin maintains a small flow gap with the valve hole through expansion and contraction, the gas entering the valve body at the intake pipe will first contact the flow turbine and drive the flow turbine to rotate. During this process, the collision and rotation of the flow turbine on the gas material entering the intake pipe will help to decelerate the circulating gas to a certain extent, so that the gas entering the valve body can slow down the speed of entering the valve hole, thereby preventing the flow speed of the gap between the ejector pin and the valve hole from suddenly accelerating, thereby helping to ensure the accuracy of the flow regulation by the expansion and contraction of the ejector pin.

[0014] The utility model provides a pressure sensor and a pressure display, and the gas flowing through the valve hole will flow into the connecting pipe. When the gas flows through the connecting pipe, the pressure sensor will detect the pressure of the gas and display it in real time through the pressure display, so that manual adjustment can be made according to the displayed data on the pressure display.

During this period, due to the characteristics of different diameters of various parts of the ejector pin 4, the ejector pin 4 can achieve different degrees of blocking of the valve hole 5, thereby realizing the flow regulation of the flow in the valve hole 5. When the ejector pin 4 maintains a small flow gap with the valve hole 5 through expansion and contraction, the gas entering the valve body 1 at the intake pipe 13 will first contact the flow turbine 9 and drive the flow turbine 9 to rotate. In this process, the collision and rotation of the flow turbine 9 on the gas material entering the intake pipe 13 will help to decelerate the circulating gas to a certain extent, so that the gas entering the valve body 1 can slow down the speed of entering the valve hole 5, and then the flow speed of the gap between the ejector pin 4 and the valve hole 5 will not appear in a sudden acceleration state, thereby helping to ensure the accuracy of the flow regulation of the ejector pin 4 by expansion and contraction.

[0022] The air inlet duct 13 is located above the flow turbine 9 .

[0023] One side of the valve body 1 is connected to a connecting pipe 15 via a connecting piece 14 .

[0027] The working principle and use process of the utility model are as follows: first, the operation of the cylinder 2 will drive the ejector pin 4 to be inserted into the valve hole 5. During this period, due to the characteristics of different diameters of various parts of the ejector pin 4, the ejector pin 4 can achieve different degrees of blocking of the valve hole 5, thereby realizing the flow regulation of the flow in the valve hole 5. When the ejector pin 4 maintains a small flow gap with the valve hole 5 through expansion and contraction, the gas entering the valve body 1 at the intake pipe 13 will first contact the flow turbine 9 and drive the flow turbine 9 to rotate. In this process, the collision and rotation of the flow turbine 9 on the gas material entering the intake pipe 13 will help to decelerate the circulating gas to a certain extent, so that the gas entering the valve body 1 can slow down the speed of entering the valve hole 5, thereby preventing the flow speed in the gap between the ejector pin 4 and the valve hole 5 from suddenly increasing. The cylinder 2 drives the ejector pin 4 to expand and contract the flow aperture in the valve hole 5, and drives the slide bar 10 to slide through the connecting block 3 until the second limit block 12 slides to the fixed ring block 8 and drives the fixed ring block 8 and the flow turbine 9 to move to one side, so that the flow turbine 9 can gradually break away from the bottom of the intake pipe 13, so that the gas flowing into the intake pipe 13 is not blocked to meet the normal flow rate requirements when the valve hole 5 is released. In addition, by setting a pressure sensor 16 and a pressure display 17, the gas flowing through the valve hole 5 will flow into the connecting pipe 15. When the gas flows through the connecting pipe 15, the pressure sensor 16 will detect the pressure of the gas and display it in real time through the pressure display 17, so that it is convenient for manual adjustment according to the display data on the pressure display 17.
