In order to ensure that the valve stem moves smoothly in the valve body and is not scratched or worn by the valve body, a sleeve is generally installed between the inner wall of the valve body and the valve stem as a medium to ensure this, so a valve body pressing sleeve device is provided.

[0003] At present, the sleeve is pressed in when the valve body is placed freely on the workbench, and the sleeve is placed above the pressing part of the valve body, and is knocked in with a hammer under the guidance of the guide rod.

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] The existing device cannot monitor the pressure change between the guide rod and the press. Due to the different clamping forces of valve sleeves and valve stems of different types and materials, the stability of the valve sleeve after fixation is affected.

[0021] In view of this, a valve body pressing sleeve device is provided. Through the cooperation between the outer shell, the pressure sensor and the limit rod, real-time monitoring of the pressure size is realized. Different pressures can be set when installing different types of valve sleeves. The pressing is stopped when the pressure value is reached, thereby avoiding the situation where the valve body is not fixed tightly or damaged due to excessive or insufficient pressure. The problem that the existing device cannot monitor the pressure change between the guide rod and the press, and the stability of the valve sleeve after fixation is affected due to the different pressing forces of valve sleeves and valve stems of different types and materials, is solved.

[0022] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0023] Embodiment 1: Figure 1 , 2As can be seen from Figure 4, a valve body pressing device comprises a frame 1, a hydraulic cylinder 2 is installed on the top of the frame 1, and the model of the hydraulic cylinder 2 is not limited. A pressing seat 10, a valve body 9, a valve sleeve 8 and a guide rod 7 are arranged at the lower inner side of the frame 1, and a monitoring mechanism is arranged at the lower part of the hydraulic cylinder 2. The monitoring mechanism comprises a shell 14, a pressure sensor 15, a slider 16, a pressure block 17, a controller 20 and a buzzer 19. The top of the shell 14 is fixedly connected to the output end of the hydraulic cylinder 2, and a pressure sensor 15 is installed on the inner side of the shell 14. The model of the pressure sensor 15 is not limited. The monitoring end of the pressure sensor 15 is fitted with a slider 16 that is slidably engaged with the inner wall of the shell 14, and the slider 16 can move inside the shell 14. The bottom of the slider 16 is fixedly connected to a pressure block 17 that is movably connected to the bottom through hole of the shell 14. The two sides of the shell 14 are respectively fixedly connected to the controller 20 and the buzzer 19, and the models of the controller 20 and the buzzer 19 are not limited.

[0024] In the specific implementation process, it is worth pointing out that through the cooperation between the pressing block 17, the controller 20 and the buzzer 19, the real-time monitoring of the pressure size is realized. Different pressures can be set when installing different types of valve sleeves. When the pressure value is reached, the pressing is stopped, which avoids the situation that the valve body is not fixed tightly or damaged due to excessive or insufficient pressure. The existing device cannot monitor the pressure change between the guide rod and the press, and the stability of the valve sleeve after fixation is affected due to the different pressing forces of valve sleeves and valve stems of different types and materials.

[0025] Furthermore, the through hole of the slider 16 is movably connected to a limit rod 18, and both ends of the limit rod 18 are fixedly connected to the inner side of the housing 14;

[0026] In the specific implementation process, it is worth pointing out that the limit rod 18 can limit the slider 16 to move only up and down;

[0027] Furthermore, a round block 6 is movably connected to the upper part of the outer wall of the guide rod 7, a sliding sleeve 4 is fixedly connected to the outer side of the round block 6, and a sliding rail 3 fixed to the inner side of the frame 1 is slidably clamped on the inner wall of the sliding sleeve 4. The sliding sleeve 4 can move on the outer side of the sliding rail 3, and a first spring 5 is movably connected to the outer side of the sliding rail 3, and the two ends of the first spring 5 are respectively fixedly connected to the bottom of the sliding sleeve 4 and the bottom of the sliding rail 3;

[0028] In the specific implementation process, it is worth pointing out that the device can drive the round block 6 to press against the guide rod 7 for positioning by relying on the elastic deformation of the first spring 5, so as to prevent the guide rod 7 from moving randomly before the sleeve is pressed;

[0029] Specifically, when using the valve body pressing device, the user can place the pressing seat 10, valve body 9, valve sleeve 8 and guide rod 7 in sequence, and then start the hydraulic cylinder 2. The hydraulic cylinder 2 can drive the pressing block 17 to move downward and press the guide rod 7. After pressing, the pressure sensor 15 can monitor the pressure change. If the pressure reaches the set value, the signal will be sent to the controller 20. The controller 20 can control the hydraulic cylinder 2 to stop moving and reset. At the same time, the controller 20 controls the buzzer 19 to make a sound to remind that the work is completed, which is convenient for continuous operation.

[0030] Embodiment 2: By Figure 1-3 It can be seen that a positioning block 11 is fixedly connected to the bottom of the sleeve pressing seat 10, and the outer side of the positioning block 11 is movably connected to the inner side of the frame 1;

[0031] In the specific implementation process, it is worth pointing out that the shape of the top of the pressing sleeve seat 10 is different, and the size is the same as the corresponding valve body 9. The positioning block 11 can move inside the frame body 1 to achieve the positioning of the pressing sleeve seat 10;

[0032] Further, the outer groove of the pressing sleeve seat 10 is movably connected to a curved rod 12, the outer wall of the curved rod 12 is movably connected to the lower cavity of the frame body 1, the curved rod 12 can move in the lower cavity of the frame body 1, and the outer side of the curved rod 12 is movably connected to a second spring 13, and the two ends of the second spring 13 are respectively fixedly connected to one side of the curved rod 12 and the inner side of the cavity of the frame body 1;

[0033] In the specific implementation process, it is worth pointing out that the device can drive the bent rod 12 to always be inserted into the groove of the pressing sleeve seat 10 for positioning by relying on the elastic deformation of the second spring 13;

[0034] Specifically, on the basis of the above-mentioned first embodiment, through the cooperation between the pressing sleeve seat 10, the bent rod 12 and the second spring 13, the quick disassembly of different types of pressing sleeve seats 10 is achieved, which is convenient for users to operate and improves work efficiency.
