Description

Technical Field

[0001] The invention relates to the technical field of ball valves, and in particular to a self-cleaning high-efficiency ball valve and a cleaning method. Background Art

[0002] The ball valve is a control valve widely used in various industrial fields. Its main function is to open, close and regulate the fluid by rotating the ball. Traditional valves often have problems such as poor fluid flow and wear during the opening and closing process. Due to its simple structure, good sealing performance and low flow resistance, the ball valve is increasingly used in the fields of petroleum, chemical industry, water supply, etc. Its working principle is to align or deviate the channel of the ball with the pipeline by rotating the valve stem, thereby achieving fluid flow control. With the development of industrial automation, the design and manufacturing technology of ball valves are also constantly improving, and the trend of intelligence and remote control is becoming increasingly obvious, making ball valves play an increasingly important role in modern industry.

[0003] The invention patent with application number: CN202310506372.0 and publication number: CN116357764A (hereinafter referred to as "prior art 1") discloses a ball valve structure for keeping the inside of the ball valve clean, including a valve housing and a valve core, a valve ball with a valve core is placed in a spherical cavity formed by a combination of the housing and a sealing plate, and the water inlet inclined hole and the water outlet inclined hole opened on the perforated inner wall both penetrate the outer wall of the valve ball.

[0004] The specification of prior art 1 discloses a ball valve structure for keeping the inside of the ball valve clean. When in use, an inclined water inlet hole and an inclined water outlet hole are opened in the medium flow perforation of the valve ball, and the two are used to connect the medium channel of the valve ball with the gap cavity between the valve ball and the valve housing. When the medium flows through the valve, the medium enters the gap cavity from the inclined water inlet hole and flows out from the inclined water outlet hole. By cooperating with the inclined water inlet hole and the inclined water outlet hole, a backflow is formed in the gap cavity, so that the cavity can be flushed and cleaned by the flow of the medium during the flow process. However, in actual applications, when the ball valve is used for a long time, the surface of the ball valve is prone to residual fluid to form stains, thereby affecting the sealing between the valve ball and the main valve body during the opening and closing process of the ball valve, thereby causing valve body leakage. Cleaning the inside of the valve core cavity only by cleaning the cleaning medium will cause a lot of dirt to remain inside the valve core cavity, and the cleaning effect is poor.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0035] See also Figure 1-3 As shown, this embodiment discloses a self-cleaning high-efficiency ball valve, comprising: a ball valve body 101 and a self-cleaning device, wherein the ball valve body 101 is used to be installed between two pipes 102 to control the water flow between the two adjacent pipes 102, and the two pipes 102 are both provided with water-permeable holes 103; the self-cleaning device is installed inside the valve core cavity 104 of the ball valve body 101;

[0036] The self-cleaning device includes a moving frame 105 slidably mounted inside the valve core cavity 104, a guide assembly slidably mounted on the valve core cavity 104, an elastic member 106 sleeved on the guide assembly, a turbine 107 rotatably mounted on the moving frame 105, and a rotating frame 108 fixedly mounted on the end surface of the turbine 107, the guide assembly is connected to the moving frame 105, one end of the elastic member 106 is connected to the guide assembly, and the other end is connected to the inner wall of the valve core cavity 104, and a plurality of bristles 109 are arranged on the rotating frame 108, and the bristles 109 are used to contact the inner wall of the valve core cavity 104;

[0037] The present invention mainly comprises a ball valve body 101 and a self-cleaning device. During the regular maintenance and upkeep of the ball valve body 101, the self-cleaning device is used to clean the valve core cavity 104 inside the ball valve body 101. During actual use, the valve is first closed and the water permeable hole 103 is opened. At this time, high-pressure liquid is introduced into the water source from the inlet ends of the two pipes 102 respectively. When the high-pressure liquid impacts the turbine 107, since the fins on the turbine 107 are arranged in an arc shape, the turbine 107 rotates under the action of the high-pressure liquid. After the rotation of the turbine 107, the rotating frame 108 is driven to rotate. The rotating frame 108 drives the bristles 109 to continuously clean the valve core cavity 104. The impurities brushed by the high-pressure liquid are ejected from the water permeable hole 103 to complete the cleaning. Since the ball valve body 101 is closed, the water hole 111 on the ball 110 of the ball valve body 101 cannot reach For cleaning, therefore, it is necessary to close the water source again, then open the ball valve body 101, and close the water permeable hole 103. At this time, the water through hole 111 makes the two pipes 102 interconnected. At this time, the high-pressure liquid is introduced into one of the pipes 102 again. At this time, the high-pressure liquid acts on the movable frame 105 and pushes the movable frame 105 to overcome the elastic force of the elastic member 106 and move to the water through hole 111. In this process, the rotating frame 108 drives the bristles 109 to continuously brush the valve core cavity 104 and the inner wall of the water through hole 111, and the stains are discharged from the other pipe 102 by the high-pressure liquid. After cleaning, stop introducing the high-pressure water source, and the movable frame 105 is reset under the action of the elastic member 106; the advantage of this arrangement is that when water is passed through the pipe 102, the ball valve body 101 can always be self-cleaned to ensure the cleanliness of the inside of the ball valve body 101.

[0038] In some embodiments, a ball 110 is provided inside the valve core cavity 104, and the ball 110 is rotatably sealed and connected to the valve core cavity 104. A water hole 111 is provided on the ball 110. A jaw groove 112 is provided at the end of the rotating frame 108, and a sliding ball 113 is rotatably provided inside the jaw groove 112. A sliding groove is provided on the ball 110, and there are two sliding grooves, which are vertically arranged. The rotating frame 108 is used to slide on the two sliding grooves through the sliding ball 113.

[0039] During actual use, after the ball 110 inside the valve core cavity 104 rotates, the water hole 111 is connected to the two pipes 102. In this process, when the ball 110 rotates, it contacts the sliding ball 113 inside the jaw groove 112 and realizes rotational cooperation; the advantage of this setting is that it reduces the friction between the rotating frame 108 and the ball 110, and uses rotational friction instead of sliding friction, which makes the service life of the ball 110 longer.

[0040] In some embodiments, an extension portion 114 is disposed inside the valve core cavity 104 , the guide assembly is slidably connected to the extension portion 114 , and the end surface of the movable frame 105 is used for slidably connecting to the end surface of the extension portion 114 .

[0041] In actual use, the extension portion 114 is an annular structure. The annular extension portion 114 and the valve core cavity 104 form an integrated structure, and the guide assembly is used for sliding connection with the extension portion 114 .

[0042] In some embodiments, the guide assembly includes a guide rod 115 and a guide hole 116, the guide hole 116 is arranged on the extension portion 114, the guide rod 115 is fixedly connected to the movable frame 105, the guide rod 115 is slidably connected to the guide hole 116, the elastic member 106 is sleeved on the guide rod 115, one end of the elastic member 106 is connected to the guide rod 115, and the other end is connected to the extension portion 114.

[0043] In actual use, when the movable frame 105 slides inside the valve core chamber 104, it drives the guide rod 115 to slide inside the guide hole 116. The main function of the guide rod 115 is to guide the movement of the movable frame 105, so that the movable frame 105 is more stable during the movement.

[0044] In some embodiments, a limiting plate 117 is disposed at the end of the guide rod 115 , a mounting groove 118 is disposed on the extension portion 114 , one end of the elastic member 106 is disposed inside the mounting groove 118 , and the other end is connected to the limiting plate 117 .

[0045] In actual use, the purpose of providing the limiting piece 117 is to facilitate limiting the guide rod 115 and prevent the guide rod 115 from being disengaged from the guide hole 116 .

[0046] In some embodiments, a support ring 119 is disposed on the moving frame 105 , and the turbine 107 is rotatably connected to the moving frame 105 via the support ring 119 .

[0047] In actual use, the support ring 119 is provided for the purpose of installing the turbine 107 , and the turbine 107 is rotatably installed on the mobile frame 105 through the support ring 119 .

[0048] In some embodiments, an inclined surface 120 is disposed on the end surface of the moving frame 105 and the end surface of the extension portion 114 that contacts each other.

[0049] In actual use, the purpose of setting the end surface of the movable frame 105 and the end surface of the extension portion 114 that contact each other as the inclined surface 120 is to facilitate the fitting of the end surface of the movable frame 105 and the extension portion 114.

[0050] In some embodiments, connecting ribs 121 are disposed on the rotating frame 108 .

[0051] In actual use, the main purpose of providing the connecting ribs 121 is to support the rotating frame 108 so that the rotating frame 108 is more stable when rotating.

[0052] The present invention also includes a method for cleaning a self-cleaning high-efficiency ball valve, comprising the following steps:

[0053] S1: Install the ball valve body 101 between two pipes 102;

[0054] S2: close the ball valve body 101, and the water flow flushes on the turbine 107, causing the turbine 107 to rotate;

[0055] S3: The turbine 107 rotates and drives the rotating frame 108 to rotate;

[0056] S4: The rotating frame 108 rotates to drive the brush 109 to rotate, thereby cleaning the stains on the inner wall of the ball valve body 101;

[0057] S5: The ball valve body 101 is opened, and the rotating frame 108 is no longer blocked.

[0058] S6: Turn off the water source, and the movable frame 105 is reset under the action of the elastic member 106.

[0059] 10. A cleaning method for a self-cleaning high-efficiency ball valve according to claim 9, characterized in that: in steps S1-S4, water sources are introduced from two different pipes 102 respectively, and the water sources respectively drive the self-cleaning devices at both ends of the valve core cavity 104 to clean the valve core cavity 104.

[0060] In some embodiments, in order to accurately evaluate the cleaning effect inside the ball valve body 101, the cleaning effect of the ball valve is calculated using the following formula:

[0061]

[0062] Among them, C: the cleaning effect inside the ball valve, which indicates the degree of cleanliness inside the ball valve. It can usually be expressed as a dimensionless value, and the higher the value, the better the cleaning effect; P: the pollution degree of the water flow (unit: mg / L, pollutant concentration), which indicates the mass of pollutants present in a unit volume of water. The higher the pollution degree, the more impurities and pollutants there are in the water flow, which reduces the cleaning effect; V: the speed of the water flow (unit: m / s); N: the speed of the turbine (unit: rpm); K: a constant; A: the effective contact area of ​​the ball valve (unit: m 2 ) Among them, n and m are indexes used to adjust the influence of water flow velocity and pollution degree, usually n>0, and m>0; c is a constant used to avoid the problem of zero denominator when the turbine speed is zero;

[0063] In actual use, since the water flow velocity will indirectly affect the turbine speed, the turbine speed needs to be calculated by the water flow velocity. The formula is as follows:

[0064]

[0065] In actual use, Q is the flow rate, A is the cross-sectional area of ​​the pipe, Q is measured by the flow meter inside the pipe, and the cross-sectional area of ​​the pipe is measured by a vernier caliper, and then the water flow velocity V is calculated;

[0066] The relationship between the turbine speed and the water flow velocity can be expressed by the following formula:

[0067]

[0068] Where D is the diameter of the turbine, k is a constant that depends on the design and shape of the turbine and is usually an empirical value that reflects the rotational force exerted by the water flow on the turbine.

[0069] At the same time, the flushing of high-pressure water flow will also clean the water holes of the ball inside the valve core cavity. In the above formula, A represents the effective area of ​​the ball valve that is in contact with the water flow, and the unit is m 2 (square meters). This area determines the degree of contact between the water flow and the valve body. The larger the contact area, the greater the potential for cleaning effect.

[0070] In the above variables:

[0071] The pollution degree P of the water flow is measured by a water quality monitoring instrument, specifically a portable water quality analyzer in the prior art. In actual use, the water overflowing from the water permeable hole after closing the ball valve body is collected and tested, and the water flow pollution degree P measured by the water quality analyzer is recorded;

[0072] In actual use, as an optional implementation, in this embodiment, the specific model of the ball valve body is AV-100-BV, the pipe diameter is 100 mm, and the effective cross-sectional area of ​​the ball and water in the inner area of ​​the ball valve body can be calculated as A=0.785m 2 .

[0073] K is a constant, the purpose of which is to make the calculated result an integer for easy recording.

[0074] The water flow velocity was measured by a flow meter and a vernier caliper on the water flow rate Q and the inner diameter D of the pipe, and the result was V = 3.0 m / s.

[0075] The staff used a portable water quality analyzer to detect the pollution level of the water flow, which was p = 0.1 mg / L;

[0076] The influence index n of flow velocity on pollution degree needs to be obtained through experiments. The specific method is as follows:

[0077] First, collect water sources and experiment with different flow rates of water sources, keeping other variables unchanged. Other variables mainly refer to the temperature, pH value and pollutant concentration of the water source. Then collect data and test at different flow rates. Collect water samples regularly, test the pollutant concentration, and record the flow rate. Then analyze these data. First, establish a relationship model and use the following formula for calculation: C = k·V n .

[0078] As an optional implementation, the following is the data information of flow rate and pollutant concentration:

[0079]

[0080]

[0081] Among them, k is a constant and n is the influence index. Through logarithmic transformation, the equation can be linearized:

[0082] log(C)=log(k)+n·log(V)

[0083] like Figure 4 As shown, the slope n, that is, the impact index n of the pollution degree, can be obtained through linear regression analysis.

[0084] In the linear relationship after logarithmic transformation, m is the slope. It indicates the degree of influence of the logarithmic change of flow velocity on the logarithmic change of pollutant concentration in the logarithmic coordinate system; the slope m is directly related to the influence index n, that is, n = m = 2; therefore, in Figure 4In the logarithmic coordinate system, n and m represent the same concept, but are used in different formulas. In the logarithmic relationship, m is the slope, while in the original power law relationship, n is the influence index.

[0085] The flow rate N of the fluid is obtained by the above formula, N = 4; since the turbine rotates normally, C is not needed to avoid the problem of the denominator being zero when the turbine speed is zero, so c = 0, and since there is no need to adjust the integer, K = 1;

[0086] In summary, through calculation, it is concluded that C=720.

[0087] The staff records the cleaning effect index inside the ball valve to accurately know the cleaning effect inside the ball valve body.
