Description

Technical Field

[0001] This application relates to the field of valve assembly auxiliary devices, and more particularly to a portable installation tool for installing O-rings on IGS pneumatic diaphragm valves. Background Technology

[0002] In the assembly process of diaphragm valves, O-rings need to be installed inside the valve body to improve the overall sealing performance of the valve. The O-ring is an elastic ring structure with a groove inside the valve body. By pressing the O-ring into the groove and then installing the valve core into the valve body, the O-ring is deformed under force and seals the gaps inside the valve body, thereby improving the sealing performance of the valve body.

[0003] The existing diaphragm valve O-rings are installed manually. The user puts the O-ring into the valve body and then squeezes it to press it into the groove. When the inner diameter of the valve body is small, the user inserts a rod into the valve body and makes the end of the rod abut against the O-ring, so that the O-ring can be pressed into the groove.

[0004] The aforementioned technical solutions have the following drawbacks: during the installation of O-rings, the O-rings are prone to falling out of the groove, which makes the installation process time-consuming and laborious, causing inconvenience. Utility Model Content

[0005] To improve the efficiency of installing O-rings inside valve bodies, this application provides a portable installation tool for installing O-rings in IGS pneumatic diaphragm valves.

[0006] The portable installation tool for installing O-rings in IGS pneumatic diaphragm valves provided in this application adopts the following technical solution: A portable installation tool for installing O-rings on an IGS pneumatic diaphragm valve includes a limiting rod and a pushing rod. The limiting rod includes a base, a connecting rod, and a handle. One end of the connecting rod is connected to the base, and the other end is connected to the handle. The base is used to insert into the valve body. The pushing rod includes a sleeve and a handle. The sleeve is fitted onto the connecting rod, and the handle is located on the side of the sleeve near the handle. The sleeve is used to slide and, together with the base, to compress the O-ring.

[0007] By adopting the above technical solution, by inserting a limiting rod into the valve body, the base can be inserted into the lower side of the groove. The user can put the O-ring on the limiting rod, so that the limiting rod can bring the O-ring into the valve body. At this time, the user can push the push rod, which can make the sleeve slide and squeeze the O-ring, thereby pressing the O-ring into the groove. This allows the O-ring to be installed in a valve body with a smaller size, improving assembly efficiency.

[0008] Optionally, a rounded corner is provided on the end face of the sleeve away from the handrail, and the rounded corner is provided on the outer edge of the end face of the sleeve.

[0009] By adopting the above technical solution, by opening a rounded corner on the sleeve, the end face of the sleeve can be inserted into the O-ring. When the user pushes the push rod, the rounded corner on the sleeve can be made to abut against the O-ring, so that the O-ring can be quickly inserted into the groove.

[0010] A portable installation tool for installing O-rings in an IGS pneumatic diaphragm valve includes an installation rod and a limiting block. The limiting block is inserted into the valve body and located on one side of a groove. The installation rod is inserted into the valve body and presses the O-ring.

[0011] By adopting the above technical solution, a limiting block is set inside the valve body, which can block the passage inside the valve body. At this time, the user uses an installation rod to squeeze the O-ring so that the O-ring can be squeezed onto the limiting block and into the groove, which is convenient for use.

[0012] Optionally, the mounting rod includes a pressure block and a gripping rod, the pressure block being rotatably connected to the gripping rod, and the pressure block being used to insert into the valve housing and compress the O-ring.

[0013] By adopting the above technical solution, and by setting a handle on the pressure block, the user can insert the handle into the valve body and control the position of the pressure block by holding the handle, thereby enabling the pressure block to press the O-ring into the groove.

[0014] Optionally, a universal joint is provided between the pressure block and the handle, and the handle is rotatably connected to the pressure block through the universal joint.

[0015] By adopting the above technical solution, and by setting a universal joint between the pressure block and the handle, the handle can rotate relative to the pressure block in different directions, which further facilitates the user to move the pressure block and squeeze the O-ring into the groove.

[0016] Optionally, the pressure block is provided with a plurality of balls, and the pressure block abuts against the limiting block through the balls.

[0017] By adopting the above technical solution, by setting ball bearings on the pressure block, the ball bearings can abut against the limit block. When the user moves the pressure block, the ball bearings roll on the limit block, thereby reducing the friction between the pressure block and the limit block.

[0018] Optionally, an abutment is provided at one end of the pressure block. The abutment is elastic and is used to abut against the O-ring.

[0019] By adopting the above technical solution, by setting an abutment on the pressure block, the abutment is used to press the O-ring into the groove. The abutment is elastic, which can reduce the probability of wear or tear on the O-ring.

[0020] Optionally, the limiting block is provided with a hanging ring, and the end of the pressing block away from the abutment is provided with a hook.

[0021] By adopting the above technical solution, by setting a hanging ring on the limit block and a hook on the pressure block, the hook can be hung on the hanging ring, thereby making it convenient for users to remove the limit block from the valve body.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By inserting a limiting rod into the valve body, the base can be inserted into the lower side of the groove. The user can put the O-ring on the limiting rod, so that the limiting rod can bring the O-ring into the valve body. At this time, the user pushes the push rod, which can make the sleeve slide and squeeze the O-ring, thereby pressing the O-ring into the groove. This allows the O-ring to be installed in a smaller valve body, improving assembly efficiency. 2. By setting a limiting block inside the valve body, the limiting block can block the passage inside the valve body. At this time, the user uses an installation rod to squeeze the O-ring so that the O-ring can be on the limiting block and squeezed into the groove, which is convenient for use. 3. By setting a universal joint between the pressure block and the handle, the handle can rotate relative to the pressure block in different directions, which further facilitates the user to move the pressure block and squeeze the O-ring into the groove.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1 This application discloses a portable installation tool for installing O-rings on IGS pneumatic diaphragm valves, referring to... Figure 1 and Figure 2 It includes a limiting rod 1 and a pushing rod 2. The limiting rod 1 is used to insert into the valve housing 31, and the pushing rod 2 is sleeved on the limiting rod 1. The pushing rod 2 is used to push the O-ring 32 into the groove 311 in the valve housing 31.

[0033] Reference Figure 1 The valve housing 31 has a channel for fluid flow, and a groove 311 is formed within the channel. The O-ring 32 is elastic, and the user needs to place the O-ring 32 into the groove 311 so that the O-ring 32 is engaged within the valve housing 31, thereby improving the sealing performance of the valve housing 31. When the valve housing 31 is small, the channel within the valve housing 31 is narrow, making it difficult for the user to manually install the O-ring.

[0034] Reference Figure 1 and Figure 2 The limiting rod 1 includes a base 11, a connecting rod 12, and a handle 13. One end of the connecting rod 12 is connected to the base 11, and the other end is connected to the handle 13. The limiting rod 1 is used to insert into the valve body 31. The push rod 2 includes a sleeve 21 and a handle 22. The sleeve 21 is a cylindrical structure and is sleeved on the connecting rod 12. The handle 22 is fixed on the sleeve 21 on the side near the handle 13. The user places the O-ring 32 onto the limiting rod 1, positioning it between the base 11 and the sleeve 21. Then, the base 11 of the limiting rod 1 is inserted into the valve housing 31, allowing the O-ring 32 to be positioned within the valve housing 31. The base 11 is located below the groove 311, and the sleeve 21 is located above the groove 311. The user then slides the sleeve 21 via the handle 22, causing it to slide and press against the O-ring 32. The sleeve 21 and the base 11 together press against the O-ring 32, pressing it into the groove 311 on the inner wall of the valve housing 31, thus achieving the purpose of installing the O-ring 32. The base 11 acts as a limiting element, allowing the O-ring 32 to be pressed into the groove 311.

[0035] Reference Figure 1 A rounded corner 211 is provided on the end face of the sleeve 21 away from the handrail 22. The rounded corner 211 is provided around the outer ring of the sleeve 21. When the sleeve 21 slides and presses the O-ring 32, the rounded corner 211 contacts the O-ring 32, so that the O-ring 32 can remain round and be pressed into the groove 311.

[0036] Example 2 This application discloses a portable installation tool for installing O-rings on IGS pneumatic diaphragm valves, referring to... Figure 3 , Figure 4 and Figure 5 The device includes an installation rod 4 and a limiting block 5. The limiting block 5 is a cylindrical structure and is positioned inside the valve housing 31 and below the groove 311. The limiting block 5 is used to block the passage inside the valve housing 31, allowing the user to place the O-ring 32 inside the valve housing 31 and use the installation rod 4 to press the O-ring 32, causing the O-ring 32 to engage in the groove 311.

[0037] Reference Figure 4 The installation rod 4 includes a pressure block 41 and a handle 42. One end of the handle 42 is connected to the pressure block 41, which is used to extend into the valve body 31 and compress the O-ring 32. A bearing seat 421 is installed at the end of the handle 42, and the bearing seat 421 is rotatably connected to the pressure block 41. The user can rotate the handle 42 relative to the pressure block 41, thereby allowing the installation rod 4 to be inserted into valve bodies 31 of different inner diameters and to install the O-ring 32.

[0038] Reference Figure 4 The pressure block 41 has an abutment 43 at one end. The abutment 43 is made of elastic material such as rubber. When the pressure block 41 is placed inside the valve body 31, the abutment 43 abuts against the O-ring 32, thereby reducing the chance of the O-ring 32 being damaged when it is installed.

[0039] Reference Figure 5 A hanging ring 51 is provided at the center of the limiting block 5, and a hook 44 is provided on the end of the pressure block 41 away from the abutment 43. The hook 44 is used to engage with the hanging ring 51. When the valve body 31 is deep, the user can hang the limiting block 5 with the installation rod 4 and install the limiting block 5 into the valve body 31. After the O-ring 32 is installed, the user can use the installation rod 4 to remove the limiting block 5.

[0040] Reference Figure 6 Multiple balls 423 are provided at the bottom of the pressure block 41. The balls 423 are embedded in the pressure block 41 and rotate in connection with the pressure block 41. When the user presses the pressure block 41 onto the limit block 5, the pressure block 41 can slide on the limit block 5 through the balls 423, which further facilitates the user to move the pressure block 41 and control the pressure block 41 to squeeze the O-ring 32.

[0041] Reference Figure 7 In other embodiments, a universal joint 422 is provided at the end of the handle 42, and the handle 42 is rotatably connected to the pressure block 41 through the universal joint 422. The user can rotate the handle 42 to different directions, thereby facilitating the user to control the movement of the pressure block 41 and compress the O-ring 32 through the handle 42.

[0042] The implementation principle of this application embodiment is as follows: By setting a limiting rod 1 or a limiting block 5 inside the valve housing 31, the limiting rod 1 or the limiting block 5 can block the channel inside the valve housing 31 and be located on the lower side of the groove 311. When the user installs the O-ring 32, the probability of the O-ring 32 falling out of the channel inside the valve housing 31 can be reduced, making it convenient to use. By setting a push rod 2 or an installation rod 4, the user can control the movement of the push rod 2 or the installation rod 4 outside the valve housing 31, thereby causing the push rod 2 or the installation rod 4 to squeeze the O-ring 32, so that the O-ring 32 can be pressed into the groove 311.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
