Description

Technical Field

[0001] The present invention relates to the technical field of sealing ring detection tools, in particular to a rotating Gly ring cross-sectional width detection device and a detection method thereof. Background Art

[0002] Currently, a type of sealing ring is commonly used on machinery and equipment in the pharmaceutical, chemical, food, and beverage industries. Rotating Glyd Rings are composed of a PTFE slip ring and an elastomer. The rotating Glyd Rings used in some devices must not only achieve reliable sealing, but also have a sufficiently low coefficient of friction to ensure smooth operation. Therefore, the cross-sectional width of the rotating Glyd Ring must be precisely controlled at all locations. Otherwise, inconsistent cross-sectional widths can lead to poor sealing and non-smooth rotation in contact with the device.

[0003] In the past, calipers were commonly used to measure the cross-sectional width of rotating Glyd Rings. However, due to individual variations in force and angle, the measurement results varied widely. Testing every position of a rotating Glyd Ring took a long time and accuracy was not guaranteed. Furthermore, this tool could not simultaneously test the sealing performance of the rotating Glyd Ring. Summary of the Invention

[0004] The present invention proposes a detection device and a detection method that can conveniently detect the cross-sectional width of a rotating Glyer ring in all directions and simultaneously detect the sealing performance of the rotating Glyer ring with accurate and rapid measurement, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A rotating Glay ring cross-sectional width detection device comprises a fixed tube and a core shaft, wherein the core shaft can be plugged into one end of the fixed tube, and an inner conical tube is movably sleeved on the outer peripheral surface of the core shaft, wherein the inner conical tube is a tube whose diameter gradually changes from small to large and is internally connected, and the diameter of the core shaft is the same as the minimum diameter of the inner conical tube. When the core shaft is plugged into one end of the fixed tube, the fixed tube is placed in the direction of the large diameter of the inner conical tube, and the outer wall of the fixed tube is marked with scale values ​​of different distances corresponding to the inner diameter of the inner conical tube and the inner diameter of a detection placement groove (11), that is, the height of the scale value is the same as the overall height of the inner conical tube, and the scale value brings different distances to the diameter values ​​at different positions of the inner conical tube, and the scale value is calculated based on the value of the inner conical tube diameter change from large to small and the inner diameter value of the detection placement groove (11): scale value = (diameter of a certain point of the inner conical tube - inner diameter d of the detection placement groove (11)) / 2, that is, the width range value of the rotating Glay ring.

[0007] A detection placement groove is also provided at the sleeve joint end of the fixed tube and the core shaft. When the rotating grid ring is placed in the detection placement groove, the inner wall of the inner cone tube conflicts with the outer periphery of the rotating grid ring. The diameter of the inner cone tube gradually expands from top to bottom, while the reading of the scale value on the fixed tube gradually increases from bottom to top, and the reading is the distance between the inner wall of the detection placement groove and the inner wall of the inner cone tube at the corresponding height position, that is, the cross-sectional width of the rotating grid ring. When the rotating grid ring contacts the inner wall of the inner cone tube, the larger the cross-sectional width of the rotating grid ring, the larger the inner diameter of the inner cone tube at the contact position between the two, and the larger the scale value reading corresponding to the bottom of the inner cone tube, and vice versa.

[0008] Preferably, the lower end of the core shaft is a plug-in end, and the core shaft is plug-connected to the top of the fixed tube through the plug-in end, and a sealing groove is provided on the outer peripheral surface of the plug-in end, and a second sealing ring is provided in the sealing groove, and the second sealing ring contacts and seals with the inner wall of the fixed tube. The core shaft is used to guide the inner cone tube to ensure that its descending angle does not deviate. The second sealing ring is used to improve the sealing performance. When the rotating grid ring contacts the inner wall of the inner cone tube, a closed space is formed between the rotating grid ring, the inner cone tube and the core shaft, which can be used to detect the sealing performance of the rotating grid ring.

[0009] Preferably, a handle groove is provided on the outer circumference of the upper end of the inner conical tube, and a water inlet is provided at the top of the inner conical tube, the water inlet being connected to the interior of the inner conical tube. The handle groove facilitates manual lifting of the inner conical tube by a worker. The water inlet is used to inject water into the enclosed space between the rotating Glyd ring, the inner conical tube, and the core shaft, thereby testing the sealing performance of the rotating Glyd ring.

[0010] Preferably, the detection placement groove is opened on the outer edge of the top of the fixed tube, and a gasket is provided at the bottom of the detection placement groove, and a rotating Gly ring is placed on the gasket.

[0011] Preferably, the rotating Gel ring is a rotating Gel ring, and the washer is a POM gasket with two notches. POM plastic has high strength and high wear resistance, which serves to protect the rotating Gel ring and the fixed tube. The notches facilitate the removal of the rotating Gel ring.

[0012] A rotating Glay ring detection method based on the rotating Glay ring cross-sectional width detection device is characterized by comprising detecting the cross-sectional width of the rotating Glay ring:

[0013] 1) Place the fixed tube (1) vertically, place the rotating Gly ring to be tested on the washer (14) on the fixed tube (1), and connect the core shaft (2) to one end of the upper part of the fixed tube (1).

[0014] 2) The inner conical tube (3) is then sleeved onto the core shaft (2), and the fixed tube (1) with the rotating grid ring is placed inside the inner conical tube (3) in the direction of the largest diameter (in the form of an inverted cover at the mouth of the inner conical tube (3)). Since the rotating grid ring has a certain width, an inner diameter position of the inner wall of the inner conical tube is stuck against the outer periphery of the rotating grid ring. The edge of the largest diameter of the inner conical tube and the corresponding scale value on the fixed tube (1) are read to obtain the cross-sectional width value of the rotating grid ring.

[0015] Furthermore, rotating grid rings with different values ​​are classified. In addition, if a value range is set as qualified products, if the value read corresponding to the maximum diameter of the inner cone tube is not within the range value, the cross-sectional width of the rotating grid ring is judged to be unqualified. If it is within the range value, the cross-sectional width is a qualified product.

[0016] It also includes the test of the sealing performance of the rotating grid ring: water is injected into the closed space formed between the rotating grid ring, the inner cone tube and the core shaft through the water injection port. After a period of time, if water flows out or seeps out, it is judged that the sealing performance of the rotating grid ring is not good. If not, it is judged that the sealing performance is qualified.

[0017] At the same time, the pressure that the sealing performance of the rotating Gly ring can withstand can be tested by adjusting the water injection volume and water pressure of the closed space.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The structure of the device of the present invention is simple and practical. The rotating grid ring to be tested is only placed on the gasket, and then the inner cone tube is sleeved on the core shaft. The large-diameter mouth of the inner cone tube overlaps with the fixed tube in the form of an inverted cover. The edge of the maximum-diameter mouth of the inner cone tube and the corresponding scale value on the fixed tube are directly read to obtain the cross-sectional width value of the rotating grid ring, thereby realizing the detection of the cross-sectional width of the rotating grid ring. At the same time, water can be injected into the enclosed space formed between the rotating grid ring, the inner cone tube and the core shaft through the water injection port to obtain the sealing performance of the rotating grid ring.

[0020] The structure-based detection method has convenient, fast, and accurate detection steps. The cross-sectional width and sealing performance of the rotating Glyer ring can be detected with the same structure and at the same time. At the same time, the pressure that the sealing performance of the rotating Glyer ring can withstand can be detected by adjusting the water injection volume and water pressure of the enclosed space.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0028] Example 1

[0029] Reference Figure 1-5 , a rotating Glay ring cross-sectional width detection device, comprising a fixed tube 1 and a core shaft 2, the core shaft 2 and one end of the fixed tube 1 can be plugged in, the outer peripheral surface of the core shaft 2 is movably sleeved with an inner cone tube 3, the inner cone tube 3 is a tube with a diameter gradually changing from small to large and internally connected, the diameter of the core shaft 2 is the same as the minimum diameter of the inner cone tube 3, when the core shaft 2 is plugged in to one end of the fixed tube 1, the fixed tube 1 is placed in the direction of the large diameter of the inner cone tube 3, the outer wall of the fixed tube 1 is marked with scale values ​​12 of different distances corresponding to the inner cone tube 3, that is, the height of the scale value is the same as the overall height of the inner cone tube, and it is a scale value with different distances for the diameter values ​​at different positions of the inner cone tube, and its scale value 12 is calculated based on the value of the inner cone tube diameter change from large to small and the inner diameter of the detection placement groove (11): scale value = (diameter of a certain point of the inner cone tube - inner diameter d of the detection placement groove (11)) / 2, that is, the width range value of the rotating Glay ring.

[0030] Specifically, a detection placement groove 11 is further provided at the sleeve joint end of the fixed tube 1 and the core shaft 2. When the rotating grid ring 13 is placed in the detection placement groove 11, the inner wall of the inner cone tube 3 conflicts with the outer periphery of the rotating grid ring 13. The diameter of the inner cone tube 3 gradually expands from top to bottom, and the reading of the scale value 12 gradually increases from bottom to top, and the reading is the distance between the inner side wall of the detection placement groove 11 and the inner wall of the inner cone tube 3 at the corresponding height position, that is, the cross-sectional width of the rotating grid ring 13. When the rotating grid ring 13 contacts the inner wall of the inner cone tube 3, the larger the cross-sectional width of the rotating grid ring 13, the larger the inner diameter of the inner cone tube 3 at the contact position between the two, and the larger the reading of the scale value 12 corresponding to the bottom of the inner cone tube 3, and vice versa.

[0031] The lower end of the core shaft 2 is a plug-in end 21, and the core shaft 2 is plug-in connected to the top of the fixed tube 1 through the plug-in end 21, and a sealing groove 22 is provided on the outer peripheral surface of the plug-in end 21, and a sealing ring 23 is provided in the sealing groove 22, and the sealing ring 23 contacts and seals with the inner wall of the fixed tube 1. The core shaft 2 is used to guide the inner cone tube 3 to ensure that its descending angle is not offset. The sealing ring 23 is used to improve the sealing performance. When the rotating grid ring 13 contacts the inner wall of the inner cone tube 3, a closed space is formed between the rotating grid ring 13, the inner cone tube 3 and the core shaft 2, which can be used to detect the sealing performance of the rotating grid ring 13.

[0032] The outer circumference of the upper end of the inner conical tube 3 is provided with a handle groove 32. A water inlet 33 is provided at the top of the inner conical tube 3 and communicates with the interior of the inner conical tube 3. The handle groove 32 facilitates manual lifting of the inner conical tube 3. The water inlet 33 is used to inject water into the enclosed space between the rotating Glyd ring 13, the inner conical tube 3, and the core shaft 2, thereby testing the sealing performance of the rotating Glyd ring 13.

[0033] The detection placement groove 11 is opened at the outer edge of the top of the fixed tube 1. A gasket 14 is provided at the bottom of the detection placement groove 11. A rotating Gly ring 13 is placed on the gasket 14.

[0034] The rotating Glyer ring 13 is a rotating Glyer ring, and the washer 14 is a POM gasket with two notches 15. POM plastic has high strength and high wear resistance, which serves to protect the rotating Glyer ring 13 and the fixed tube 1. The notches 15 facilitate the removal of the rotating Glyer ring 13.

[0035] When the present invention is used, the rotating grid ring 13 with a fixed inner diameter to be tested is placed on the gasket 14, the inner conical tube 3 is sleeved on the core shaft 2, and the inner conical tube 3 is gradually moved downward along the core shaft 2 until the inner wall of the inner conical tube 3 contacts the rotating grid ring 13. Since the reading of the scale value 12 is the distance between the inner side wall of the detection placement groove 11 and the inner wall of the inner conical tube 3 at the corresponding position, the reading of the scale value 12 on the fixed tube 1 corresponding to the bottom of the inner conical tube 3 is the cross-sectional width of the rotating grid ring 13. At this time, water is injected into the enclosed space between the rotating grid ring 13, the inner conical tube 3 and the core shaft 2 through the water injection port 33 to realize the detection of the sealing performance of the rotating grid ring 13.

[0036] The detection steps of the present invention are simple and fast, and can realize the detection of the cross-sectional width of the entire periphery of the rotating Glyer ring 13, and can also realize the detection of the sealing performance of the rotating Glyer ring 13.

[0037] Example 2

[0038] A rotating Glay ring detection method based on the above-mentioned rotating Glay ring cross-sectional width detection device, specifically operates as follows:

[0039] (1) Including cross-sectional width detection of rotating Glay circles:

[0040] 1) Place the fixed tube 1 vertically, place the rotating Gly ring to be tested on the washer 14 on the fixed tube 1, and plug the core shaft 2 into one end of the upper part of the fixed tube 1.

[0041] 2) Then, the inner conical tube 3 is sleeved onto the core shaft 2, and the fixed tube 1 with the rotating grid ring is placed inside the inner conical tube 3 in the direction of the largest diameter, that is, the inner conical tube 3 is in the form of an inverted cover. Since the rotating grid ring has a certain width, an inner diameter position of the inner wall of the inner conical tube is stuck and interfered with the outer periphery of the rotating grid ring. The scale value corresponding to the edge of the largest diameter of the inner conical tube and the fixed tube 1 is read to obtain the cross-sectional width value of the rotating grid ring.

[0042] Furthermore, rotating grid rings with different values ​​are classified. In addition, if a value range is set as qualified products, if the value read corresponding to the maximum diameter of the inner cone tube is not within the range value, the cross-sectional width of the rotating grid ring is judged to be unqualified. If it is within the range value, the cross-sectional width is a qualified product.

[0043] (2) It also includes the test of the sealing performance of the rotating grid ring: water is injected into the closed space formed between the rotating grid ring, the inner cone tube and the core shaft through the water injection port. After a period of time, if water flows out or seeps out, it is judged that the sealing performance of the rotating grid ring is not good. If not, it is judged that the sealing performance is qualified.

[0044] At the same time, the pressure that the sealing performance of the rotating Gly ring can withstand can be tested by adjusting the water injection volume and water pressure of the closed space.

[0045] Through the above embodiments, it is possible to obtain:

[0046] The structure of the device of the present invention is simple and practical. The rotating grid ring to be tested is only placed on the gasket, and then the inner cone tube is sleeved on the core shaft. The large-diameter mouth of the inner cone tube overlaps with the fixed tube in the form of an inverted cover. The edge of the maximum-diameter mouth of the inner cone tube and the corresponding scale value on the fixed tube are directly read to obtain the cross-sectional width value of the rotating grid ring, thereby realizing the detection of the cross-sectional width of the rotating grid ring. At the same time, water can be injected into the enclosed space formed between the rotating grid ring, the inner cone tube and the core shaft through the water injection port to obtain the sealing performance of the rotating grid ring.

[0047] The structure-based detection method has convenient, fast, and accurate detection steps, and can detect the cross-sectional width and sealing of the rotating Glyer ring with the same structure and at the same time, and also includes the detection of the pressure that the sealing of the rotating Glyer ring can withstand.
