Description

Technical Field

[0001] This utility model relates to the technical field of valve installation equipment, specifically a high-efficiency installation device for float valves. Background Technology

[0002] In relevant mechanical or chemical equipment, float valves are a critical level control component, and their installation quality directly affects the performance and reliability of the entire equipment. The installation process of float valves, especially the bending of specific parts (such as the valve foot) for fixation, often suffers from several shortcomings in existing technologies. Currently, this type of installation largely relies on manual operation using general-purpose tools (such as pliers and bench vises) or simple auxiliary pressing tools. This method not only makes the entire installation process cumbersome and inefficient, but also, due to the lack of dedicated positioning and guiding mechanisms, it is difficult for operators to ensure that the position and angle of each bend are precisely consistent, resulting in poor consistency after installation and a low product qualification rate. Furthermore, during the application of bending force, the difficulty in precisely controlling the force point and magnitude can easily cause unnecessary scratches, extrusion deformation, and other damage to the float valve body, affecting its service life and sealing performance. The entire process is highly dependent on the operator's skill and physical strength, resulting in significant labor intensity. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-efficiency floating valve installation device, which solves the problems of complex operation, inaccurate positioning, low efficiency, and easy damage to the valve body in existing floating valve installation methods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency floating valve installation device, comprising three housings, with a circular cover plate fixedly connected to the top of each housing. A connecting hole is provided inside the circular cover plate, penetrating the outer surface of the cover plate. A thrust block is slidably connected inside the connecting hole. Multiple limiting holes are provided inside the middle of each housing, penetrating the outer surface of the housing. An ejector block is provided inside each limiting hole, abutting against the thrust block. A valve body is slidably connected to the bottom of each housing, with a bending hole provided inside the bottom of the housing, penetrating the outer surface of the housing.

[0005] Preferably, an L-shaped limiting block is fixedly connected to the inner surface of the outer shell, and the L-shaped limiting block is adjacent to the bending hole.

[0006] Preferably, a limiting post is fixedly connected to the outer surface of the ejector block, and the ejector block is slidably connected inside the limiting hole through the limiting post.

[0007] Preferably, a retractable post is fixedly connected to the outer surface of the ejector block adjacent to the limiting post, and an auxiliary hole is opened in the inner surface of the outer shell adjacent to the limiting hole. The auxiliary hole penetrates the outer surface of the outer shell, and the retractable post is slidably connected inside the auxiliary hole.

[0008] Preferably, a card is engaged at the end of the retracting column away from the ejector block, and the card abuts against the outer surface of the outer casing.

[0009] Preferably, a spring is provided between the inner surface of the outer shell and the outer surface of the ejector block, and the spring is sleeved on the outer surface of the retraction column.

[0010] Preferably, the ejector block is trapezoidal, the thrust block is triangular pyramidal, and the inclination of the contact surfaces of the ejector block and the thrust block are the same.

[0011] Preferably, a pressure block is fixedly connected to the lower end of the outer surface of the ejector block.

[0012] This utility model provides a high-efficiency installation device for float valves. It has the following beneficial effects:

[0013] 1. This utility model cleverly utilizes the inclined plane transmission principle by setting a triangular pyramid-shaped thrust block and a trapezoidal ejector block, and making the inclination of their contact surfaces consistent. When the operator presses down on the thrust block, a simple vertical action can be efficiently converted into multiple synchronous radial horizontal thrusts, driving the ejector block to complete the bending operation of the valve body. The overall structure is simple and reliable, significantly reducing the complexity of operation and labor intensity.

[0014] 2. This utility model uses an L-shaped limiting block to pre-position the valve body and a limiting post to ensure that the ejector block can only perform a stable linear reciprocating motion. This ensures that the pressure block that performs the final bending, the part of the valve body to be bent, and the bending hole that serves as the fulcrum are always on the same axis. Through this multi-positioning and guiding design, the accuracy and consistency of each bending operation are ensured, effectively improving the installation quality and product qualification rate.

[0015] 3. This utility model, by setting a reset mechanism composed of a retraction column, a card, and a spring between the outer shell and the ejector block, enables the device to automatically and quickly return to its initial state after completing the bending operation; the operator only needs to remove the external force, and the device can be ready for the next installation, eliminating the step of manual reset, making the entire installation process more coherent and smooth, and greatly improving the efficiency of continuous operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1 -Appendix Figure 4 This utility model provides a high-efficiency installation device for a float valve, including three outer shells 1. A circular cover plate 2 is fixedly connected to the top of the three outer shells 1. A connecting hole 3 is opened inside the circular cover plate 2, and the connecting hole 3 penetrates the outer surface of the circular cover plate 2. A thrust block 4 is slidably connected inside the connecting hole 3. A plurality of limiting holes 5 are opened inside the middle of the outer shell 1, and the limiting holes 5 penetrate the outer surface of the outer shell 1. An ejector block 6 is provided inside the limiting holes 5, and the ejector block 6 abuts against the thrust block 4. A valve body 7 is slidably connected to the bottom of the outer shell 1. A bending hole 8 is opened inside the bottom end of the outer shell 1, and the bending hole 8 penetrates the outer surface of the outer shell 1.

[0023] Specifically, this device consists of three outer shells 1 forming a stable load-bearing frame for the entire equipment. The circular cover plate 2 on top provides the necessary rigidity for the overall structure and provides a mounting base for the power input components. During installation, the connecting hole 3 on the circular cover plate 2 serves to provide a precise guiding channel for the power application process, thereby ensuring that the thrust block 4 can stably receive external pressure and start the entire mechanical linkage. The core function of the thrust block 4 is to effectively transmit a single vertical driving force to the next stage mechanism. The ejector block 6 that abuts against it, under the track constraint of the limiting hole 5, realizes the key function of smoothly converting the vertical force into a radial horizontal thrust, thereby accurately applying the power to the valve body 7 to be installed. Finally, the bending hole 8 at the bottom plays the role of forming mold and fulcrum, allowing the valve body 7 to produce a certain bending under the action of horizontal thrust, thereby realizing the rapid installation of the float valve.

[0024] An L-shaped limiting block 9 is fixedly connected to the inner surface of the outer shell 1, and the L-shaped limiting block 9 is adjacent to the bending hole 8.

[0025] Specifically, inside the outer casing 1, the L-shaped limiting block 9 stably clamps the valve body 7 in a preset position before processing, effectively avoiding offset during installation, thus providing a reliable guarantee for subsequent precise bending operations. This precise alignment is precisely to ensure that the part of the valve body 7 to be bent can perfectly match the bending hole 8, which ultimately serves as a forming fulcrum, ensuring that under pressure, the valve body 7 can produce precise and consistent bending deformation along the predetermined contour.

[0026] The outer surface of the ejector block 6 is fixedly connected to the limiting post 10, and the ejector block 6 is slidably connected to the inside of the limiting hole 5 through the limiting post 10.

[0027] Specifically, during the movement of the ejector block 6, the limiting post 10 plays a crucial guiding role. By sliding within the limiting hole 5, it ensures that the ejector block 6 can only perform precise linear reciprocating motion, thereby effectively preventing the ejector block 6 from deflecting or jamming when subjected to force, and ensuring the stability and reliability of the entire ejection action.

[0028] A retraction post 11 is fixedly connected to the outer surface of the ejector block 6 near the limiting post 10. An auxiliary hole 12 is opened inside the outer shell 1 near the limiting hole 5. The auxiliary hole 12 penetrates the outer surface of the outer shell 1, and the retraction post 11 is slidably connected inside the auxiliary hole 12.

[0029] Specifically, in order to achieve automatic reset of the ejector block 6, the retraction column 11 extending from it passes through the auxiliary hole 12 on the outer shell 1. The auxiliary hole 12 provides the necessary channel and guide for the reciprocating motion of the retraction column 11, ensuring the smooth operation of the retraction action.

[0030] The end of the retracting column 11 away from the ejector block 6 is fitted with a card 13, which abuts against the outer surface of the outer casing 1.

[0031] Specifically, in the retraction and reset mechanism, the card 13 plays the role of end limit. By engaging with the outside of the retraction column 11 and abutting against the outer wall of the housing 1, it effectively prevents the retraction column 11 from completely retracting into the housing under the elastic force of the spring 14, thereby setting a clear and reliable initial position for the entire ejection mechanism.

[0032] A spring 14 is provided between the inner surface of the outer casing 1 and the outer surface of the ejector block 6, and the spring 14 is sleeved on the outer surface of the retraction column 11.

[0033] Specifically, the spring 14 is the core power source for the automatic reset of the device. When the ejector block 6 is pushed out, the spring 14 is compressed to store elastic potential energy. Once the external force is removed, the spring 14 will immediately release energy to pull the ejector block 6 back to its original position. Its design of being sleeved on the retraction column 11 ensures the stability and centering of the spring 14 during the extension and retraction process, making the reset action faster and more reliable.

[0034] The ejector block 6 is trapezoidal, and the thrust block 4 is triangular pyramidal. The inclination of the contact surfaces of the ejector block 6 and the thrust block 4 is the same.

[0035] Specifically, the device cleverly utilizes the principle of inclined plane transmission. The triangular pyramid-shaped thrust block 4 and the trapezoidal ejector block 6 are matched by inclined planes with the same inclination. When the thrust block 4 is pressed down, it can smoothly and efficiently decompose the single vertical force into multiple radial horizontal thrusts.

[0036] A pressure block 15 is fixedly connected to the lower end of the outer surface of the ejector block 6.

[0037] Specifically, the pressure block 15, as the direct component that ultimately performs the bending action, precisely applies the horizontal thrust transmitted from the ejector block 6 to a specific position on the valve body 7. Through the specially designed contact structure of the pressure block 15, pressure can be effectively transmitted and damage to the surface of the valve body 7 can be avoided, thus ensuring the quality of the bending process.

[0038] When the device is running, the pressure block 15, the part of the valve body 7 to be bent, and the bending hole 8 are located on the same axis.

[0039] Specifically, during operation, the pressure block 15, the part of the valve body 7 to be bent, and the bending hole 8 are kept on the same axis, which is the core prerequisite for ensuring bending quality. This precise alignment ensures that the thrust applied by the pressure block 15 can be accurately applied to the position of the valve body 7 that needs the most force, and the expected bending is generated with the bending hole 8 as the standard reference, thereby eliminating defective products caused by positioning deviation.

[0040] Working principle: In actual use, the valve body 7 is inserted from the bottom of the semi-enclosed space formed by the three outer shells 1. After the non-bent part of the valve body 7 is locked by the L-shaped limiting block 9, the triangular pyramid-shaped thrust block 4 is pressed down from the connecting hole 3 through the circular cover plate 2 by an external power device. Its inclined surface then pushes the trapezoidal ejector block 6, which is in contact with it and has the same inclination. Under the guidance of the limiting post 10, the ejector block 6 overcomes the retraction post in the limiting hole 5. The spring 14 on 11 slides outward due to its elastic force, and the pressure block 15 at its lower end is located on the same axis as the bending point of the valve body 7 and the bending hole 8. It pushes the bending point of the valve body 7 against the edge of the bending hole 8 to achieve bending. When the external force is removed, the compressed spring 14 rebounds and pulls the ejector block 6 back to its original position through the retraction column 11 that passes through the auxiliary hole 12 and is limited by the end card 13. At the same time, the inclined surface of the ejector block 6 also pushes the thrust block 4 back to its initial position.
