Description

Technical Field

[0001] The utility model relates to the technical field of liquid flow meter equipment, in particular to a novel valve sleeve of a liquid flow meter. Background Art

[0002] Liquid flow meters have been widely used in various industries, including chemical, petroleum, medicine, food, etc. In the chemical industry, liquid flow meters are widely used to measure and control liquid feeding and discharge in chemical reactions; in the petroleum industry, liquid flow meters are used for oil and gas recovery, oil pipeline metering, etc.; in the pharmaceutical and food industries, liquid flow meters are used to transport and measure medicines and food raw materials. In the use of liquid flow meters, in order to control the liquid flow, we need to use valve sleeves, so as to adjust the opening and closing degree of the valve sleeves to adjust the speed and amount of fluid passing through.

[0003] The valve sleeve of a traditional liquid flowmeter is typically relatively simple in design, consisting primarily of a pipe connection and a valve core. The pipe connection typically uses a straight or curved pipe to connect the flowmeter's inlet and outlet pipes. This simple design can lead to some fluid dynamics challenges, particularly when the liquid flows through the sleeve, which can adversely affect the flow.

[0004] For example, when the fluid flows through the valve sleeve, it may not be able to effectively and stably converge in the middle position, which may cause turbulence or eddy currents during the liquid flow, making the flow state of the fluid unstable. This unstable flow state may affect the accuracy of the flow meter and cause deviations in the flow test results.

[0005] In summary, the simple design of the valve sleeve structure of the traditional liquid flowmeter may lead to some fluid dynamics challenges, including the inability of the fluid to converge stably, which may affect the accuracy of the flow test. Utility Model Content

[0006] In order to make up for the above deficiencies, the present invention provides a novel valve sleeve for a liquid flow meter, which aims to improve the problem that the traditional valve sleeve for a liquid flow meter is too simple and may affect the measurement results.

[0007] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a novel liquid flow meter valve sleeve, comprising an intermediate connecting portion, a V-shaped flow channel is opened inside the intermediate connecting portion, and a connecting assembly is provided on the outer wall of the intermediate connecting portion;

[0008] The connecting assembly includes a dynamic sealing boss and a pipe section sealing boss. The dynamic sealing boss is fixedly connected to the top of the outer wall of the intermediate connecting portion, and the pipe section sealing boss is fixedly connected to the bottom of the outer wall of the intermediate connecting portion.

[0009] As a further description of the above technical solution:

[0010] There are multiple V-shaped flow channels and they are distributed symmetrically around the center.

[0011] As a further description of the above technical solution:

[0012] A valve core is arranged inside the intermediate connecting portion.

[0013] As a further description of the above technical solution:

[0014] A sealing rubber ring is provided on one side of the dynamic sealing boss.

[0015] As a further description of the above technical solution:

[0016] The dynamic sealing shoulder and the pipe section sealing shoulder are both centrally symmetrically distributed according to the width of the middle connecting portion.

[0017] As a further description of the above technical solution:

[0018] The interior of the intermediate connecting portion is configured to be a hollow tube with a certain thickness.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the present invention, by introducing an intermediate connecting portion and a symmetrical V-shaped flow channel design in the middle of the valve sleeve structure, the liquid can be effectively and stably gathered in the middle position when flowing through the valve sleeve, thereby ensuring that the fluid passes through at a stable flow rate. This design optimization not only helps to improve the accuracy of flow testing, but also optimizes the fluid dynamics characteristics and reduces factors that may cause measurement deviations.

[0021] 2. In the present invention, the precise coordination of the dynamic sealing boss and the pipe section sealing boss ensures a tight connection between the components inside the valve sleeve, which not only improves the sealing performance inside the valve sleeve, but also effectively prevents liquid leakage and the entry of external impurities. Moreover, this integrated structural design makes the valve sleeve equipment more stable and durable, and reduces the possibility of loosening and leakage between components.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1 The utility model provides an embodiment: a novel liquid flow meter valve sleeve, comprising an intermediate connecting portion 1, a V-shaped flow channel 2 is opened inside the intermediate connecting portion 1, and a connecting component is provided on the outer wall of the intermediate connecting portion 1;

[0027] The connecting assembly includes a dynamic sealing boss 3 and a pipe section sealing boss 4. The dynamic sealing boss 3 is fixedly connected to the top of the outer wall of the intermediate connecting portion 1, and the pipe section sealing boss 4 is fixedly connected to the bottom of the outer wall of the intermediate connecting portion 1.

[0028] Specifically, the corresponding intermediate connecting part 1 is tightly connected with the dynamic sealing boss 3 and the pipe section sealing boss 4, and the corresponding V-shaped flow channel 2 is also opened in the intermediate connecting part 1, thereby realizing an integrated structure, so that the corresponding equipment has an integrated valve table with connection, circulation and sealing functions, thereby improving the overall strength.

[0029] The V-shaped flow channel 2 is provided with multiple and centrally symmetrical distributions. A valve core is provided inside the middle connecting portion 1. A sealing rubber ring is provided on one side of the dynamic sealing boss 3. The dynamic sealing boss 3 and the pipe section sealing boss 4 are centrally symmetrically distributed according to the width of the middle connecting portion 1. The interior of the middle connecting portion 1 is provided with a hollow tube with a certain thickness.

[0030] Specifically, the intermediate connecting part 1 has sufficient thickness to ensure the strength of the product and has precise accuracy, and the valve core is a special valve core that can be used in conjunction with the intermediate connecting part 1. The corresponding liquid is efficiently gathered to the valve core position through the V-shaped flow channel 2, and the corresponding pipe section sealing boss 4 is connected to the liquid inflow pipe section, and the corresponding power sealing boss 3 is sealed and connected to the power part of the flowmeter through a sealing rubber ring.

[0031] Working principle: When the liquid passes through the valve sleeve, the design of the V-shaped flow channel 2 allows the liquid to converge at the middle connection part 1 at a stable flow rate. The hollow tubular design inside the middle connection part 1 contributes to the stable flow of the fluid and cooperates with the measuring valve core to achieve accurate flow testing. The power sealing boss 3 is sealed and connected to the power part of the flowmeter, and the corresponding pipe section sealing boss 4 is connected to the liquid inlet pipe section to ensure that no leakage occurs when the liquid flows, thereby ensuring the accuracy and stability of the flowmeter.
