Description

Technical Field

[0001] The utility model relates to the technical field of two - material proportional valves, and particularly relates to a two - material proportional valve which is convenient to install. Background Technique

[0002] In the process of industrial production, it is often necessary to accurately control the mixing ratio of two or more materials to ensure product quality and production efficiency. Traditional two - material proportional valves have many inconveniences in installation, adjustment and maintenance, and it is difficult to meet the requirements of modern industrial production for high efficiency, accuracy and easy maintenance.

[0003] Most of the two - material proportional valves on the market at present have complex structures, cumbersome installations, and the adjustment accuracy and stability need to be improved. Some proportional valves require complex manual adjustment operations, which not only increase the workload of operators, but also reduce production efficiency and product quality. Traditional two - material proportional valves require multiple steps and tools in the installation process, and have high requirements for the technical level of installers. This not only increases the installation time and cost, but also easily leads to performance degradation or frequent failures due to improper installation. The adjustment mechanisms of some proportional valves are not reasonably designed, requiring complex manual adjustment operations, and it is difficult to guarantee the adjustment accuracy. This not only increases the workload of operators, but also may cause large fluctuations in the material ratio during the production process, affecting product quality.

[0004] In view of this, we have proposed a two - material proportional valve which is convenient to install. Content of the Utility Model

[0005] The purpose of the utility model is to provide a two - material proportional valve which is convenient to install, so as to solve the problems raised in the above - mentioned background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A two - material proportional valve which is convenient to install, including a valve body, an observation window is rotatably connected to the outside of the valve body, an electromagnetic valve is fixedly installed at the top of the valve body, a buckle mechanism is arranged on the outside of the valve body, and the buckle mechanism includes:

[0007] A fixed column, the fixed column is slidably attached to the outside of the valve body, and a rear caster is slidably connected to one side of the fixed column;

[0008] A front caster, the front caster is slidably connected to one side of the fixed column, and a fixing groove is opened at one end of the valve body;

[0009] A clamping column, the clamping column is slidably connected to one end of the fixing groove, a spring is fixedly installed on the clamping column, and one end of the spring is fixedly connected to a triangular block.

[0010] Preferably, one end of the fixed column away from the valve body is fixedly connected to a cylinder, one end of the fixed column away from the cylinder is rotatably connected to an air pipe, one end of the air pipe is fixedly connected to a diaphragm, the inner side of the valve body is fixedly connected to a sleeve, and one end of the sleeve is rotatably connected to a discharge pipe.

[0011] Preferably, the centers of the circular cross-sections of the clamping post and the spring are coaxial. Through the sliding fit of the fixed column on the outer side of the valve body, the valve body is initially positioned by the front caster and the rear caster. Subsequently, the sliding of the clamping post in the fixing groove, combined with the elastic force of the spring, enables the triangular block to firmly engage in the fixing groove, realizing the stable connection between the valve body and the external pipeline or equipment. This design not only simplifies the installation steps but also improves the connection reliability.

[0012] Preferably, there are multiple groups of the cylinders, and the multiple groups of cylinders are mirror-symmetrically arranged at the other end of the solenoid valve with the horizontal midline of the solenoid valve as the mirror axis. When the material ratio needs to be adjusted, the cylinder applies pressure to the diaphragm through the air pipe. The deformation of the diaphragm then pushes the discharge pipe in the sleeve to rotate, thereby changing the mixing ratio of the two materials. Since there are multiple groups of cylinders and they are mirror-symmetrically arranged with the horizontal midline of the solenoid valve as the mirror axis, this symmetrical layout ensures the accuracy and balance of the material ratio adjustment.

[0013] Preferably, there are multiple groups of the fixing grooves, and the multiple groups of fixing grooves are circumferentially arrayed around the center of the fixed column. The observation window rotatably connected to the outer side of the valve body allows the operator to directly observe the internal material flow situation without disassembling the valve body, facilitating real-time monitoring and adjustment. The solenoid valve is responsible for controlling the on-off of the material, realizing automatic control.

[0014] Preferably, there are multiple groups of the buckle mechanism, cylinder, air pipe, diaphragm, sleeve, and discharge pipe, and the multiple groups of the buckle mechanism, cylinder, air pipe, diaphragm, sleeve, and discharge pipe are symmetrically arranged on the upper and lower sides of the valve body with the horizontal midline of the valve body as the symmetry axis.

[0015] Compared with the prior art, the present utility model provides a two-material proportion valve that is easy to install, and has the following beneficial effects:

[0016] 1. For the two-material proportion valve that is easy to install, the design of the buckle mechanism greatly simplifies the installation process of the valve body, reduces the installation time and labor cost. At the same time, the easy-to-dismantle structure also facilitates subsequent maintenance and repair. Through the symmetrical layout of multiple groups of cylinders and the precise control of the diaphragm, the precise adjustment of the material ratio is realized, meeting the requirements for the accuracy of the material ratio in different production needs.

[0017] 2. The two - material proportional valve that is easy to install, with an automated solenoid valve control and pneumatic regulation system, enables more rapid and accurate adjustment of the material ratio, improves production efficiency and product quality. The design of the observation window allows operators to monitor the internal situation of the valve body in real - time, promptly discover and solve problems, and enhances the safety and stability during the production process.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a two - material proportional valve that is easy to install, including a valve body 1, an observation window 2 is rotatably connected to the outside of the valve body 1, a solenoid valve 3 is fixedly installed at the top of the valve body 1, and a buckle mechanism 4 is arranged on the outside of the valve body 1.

[0026] In an embodiment of the present utility model, the buckle mechanism 4 includes a fixed column 401. The outer side of the valve body 1 is slidably fitted with the fixed column 401. A rear clamping wheel 402 is slidably connected to one side of the fixed column 401, and a front clamping wheel 403 is slidably connected to one side of the fixed column 401. The valve body 1 serves as the main body part of the entire proportional valve, and the fixed column 401 which is slidably fitted is designed on its outer side. During installation, the fixed column 401 is slid along the outer side of the valve body 1 to a predetermined position. Subsequently, through the sliding connection of the front clamping wheel 403 and the rear clamping wheel 402, the valve body 1 is preliminarily fixed to an external pipeline or device. By utilizing the sliding of the clamping column 405 in the fixing groove 404 and cooperating with the elastic force of the spring 406, the triangular block 407 is firmly clamped into the fixing groove 404 to complete the final fixation of the valve body 1. The design of this buckle mechanism 4 greatly simplifies the installation steps and improves the installation efficiency. One end of the valve body 1 is provided with a fixing groove 404. A clamping column 405 is slidably connected to one end of the fixing groove 404. A spring 406 is fixedly installed on the clamping column 405. One end of the spring 406 is fixedly connected to a triangular block 407. When it is necessary to adjust the mixing ratio of two materials, the cylinder 501 applies pressure to the diaphragm 503 through the air pipe 502. Since multiple groups of cylinders 501 are provided and are mirror-symmetrically arranged with the horizontal midline of the solenoid valve 3 as the mirror axis, this symmetrical layout ensures the uniformity and stability of the pressure application. After being subjected to pressure, the diaphragm 503 deforms, and then drives the discharge pipe 505 in the sleeve 504 to rotate. The rotation of the discharge pipe 505 changes the mixing channel of the two materials, thereby achieving precise adjustment of the material ratio.

[0027] In an embodiment of the present utility model, one end of the fixed column 401 away from the valve body 1 is fixedly connected to a cylinder 501, one end of the fixed column 401 away from the cylinder 501 is rotatably connected to an air pipe 502, one end of the air pipe 502 is fixedly connected to a diaphragm 503, the inner side of the valve body 1 is fixedly connected to a sleeve 504, one end of the sleeve 504 is rotatably connected to a discharge pipe 505, the circular cross-section centers of the clamping column 405 and the spring 406 are coaxial, there are multiple groups of cylinders 501, and the multiple groups of cylinders 501 are mirror-symmetrically arranged at the other end of the solenoid valve 3 with the horizontal midline of the solenoid valve 3 as the mirror axis, there are multiple groups of fixing grooves 404, and the multiple groups of fixing grooves 404 are circumferentially arrayed around the center of the fixed column 401, there are multiple groups of the snap mechanism 4, the cylinder 501, the air pipe 502, the diaphragm 503, the sleeve 504 and the discharge pipe 505, and the multiple groups of the snap mechanism 4, the cylinder 501, the air pipe 502, the diaphragm 503, the sleeve 504 and the discharge pipe 505 are symmetrically arranged on the upper and lower sides of the valve body 1 with the horizontal midline of the valve body 1 as the axis of symmetry. Since there are also multiple groups of discharge pipes 505 and they are symmetrically arranged with the horizontal midline of the valve body 1 as the axis of symmetry, this design further improves the accuracy and balance of the material ratio adjustment. The observation window 2 rotatably connected to the outside of the valve body 1 allows the operator to directly observe the internal material flow situation and mixing ratio without disassembling the valve body 1, which is convenient for real-time monitoring and adjustment. The solenoid valve 3 is responsible for controlling the on-off of the material to achieve automatic control. By combining the functions of the observation window 2 and the solenoid valve 3, the operator can adjust the material ratio more flexibly to meet different production requirements.

[0028] Working principle: The valve body 1 serves as the main part of the entire proportional valve. Fixed columns 401 that fit slidably are designed on its outer side. During installation, the fixed columns 401 are slid along the outer side of the valve body 1 to a predetermined position. Subsequently, through the sliding connection of the front caster 403 and the rear caster 402, the valve body 1 is preliminarily fixed to an external pipeline or device. By utilizing the sliding of the clamping post 405 within the fixing groove 404 and in conjunction with the elastic force of the spring 406, the triangular block 407 is firmly clamped into the fixing groove 404 to complete the final fixation of the valve body 1. The design of this snap mechanism 4 greatly simplifies the installation steps and improves the installation efficiency. When it is necessary to adjust the mixing ratio of two materials, the air cylinder 501 applies pressure to the diaphragm 503 through the air pipe 502. Since multiple groups of air cylinders 501 are provided and are mirror-symmetrically arranged with the horizontal center line of the solenoid valve 3 as the mirror axis, this symmetric layout ensures the uniformity and stability of the pressure application. After being subjected to pressure, the diaphragm 503 deforms, thereby driving the discharge pipe 505 within the sleeve 504 to rotate. The rotation of the discharge pipe 505 changes the mixing channels of the two materials, thus achieving precise adjustment of the material ratio. Since multiple groups of discharge pipes 505 are also provided and are symmetrically arranged with the horizontal center line of the valve body 1 as the symmetry axis, this design further improves the accuracy and balance of the material ratio adjustment. The observation window 2 rotatably connected to the outer side of the valve body 1 allows the operator to directly observe the internal material flow condition and the mixing ratio without disassembling the valve body 1, facilitating real-time monitoring and adjustment. The solenoid valve 3 is responsible for controlling the on-off of the material to achieve automated control. By combining the functions of the observation window 2 and the solenoid valve 3, the operator can adjust the material ratio more flexibly to meet different production requirements.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
