Description

Technical Field

[0001] The utility model relates to the technical field of three - way joints, and particularly relates to a stainless - steel - lined three - way with a seal against scale formation. Background Art

[0002] A stainless - steel - lined three - way refers to a steel three - way with a stainless - steel pipe lined on its inner wall. When the stainless - steel - lined three - way is in use, an extremely thin chromium oxide film will form on the inner wall of the stainless - steel pipe. The film can prevent the stainless - steel pipe from further oxidation, improving the corrosion resistance of the stainless - steel - lined three - way. The stainless - steel - lined three - way is connected to the pipeline through flanges, and the flange of the three - way and the flange of the pipeline are connected through bolt assemblies to realize the connection and fixation of the three - way and the pipeline.

[0003] In the existing stainless - steel - lined three - way, the sealing performance at the joint inside is insufficient, and leakage problems are likely to occur. The sealing ring is more vulnerable to the influence of scale in the fluid, reducing the overall performance and service life of the three - way. Summary of the Utility Model

[0004] In view of the above - mentioned problems, the utility model discloses a stainless - steel - lined three - way with a seal against scale formation.

[0005] The technical solution of the utility model is: a stainless - steel - lined three - way with a seal against scale formation, which comprises a three - way main body, an external connecting pipe connected to the three - way main body, and a sealing and scale - preventing component arranged at the connection between the external connecting pipe and the three - way main body;

An anti - scale coating is arranged outside the first sealing ring and the second sealing ring, and a sealing clamping ring is arranged on one side of the clamping cylinder opposite to the annular connecting sleeve.

[0007] Further, two semi - annular clamping sleeves are symmetrically arranged on the inner wall of the annular clamping sleeve. The second sealing ring is composed of two semi - annular sealing gaskets respectively arranged on the semi - annular clamping sleeves. The outer wall of the annular clamping sleeve is threadedly connected with fastening rods that penetrate through the annular clamping sleeve and are respectively connected to the semi - annular clamping sleeves one by one.

[0008] Description: When using the annular clamping sleeve to clamp and fix the external connecting pipe, insert the external connecting pipe into the annular clamping sleeve, and manually rotate the fastening rod to make the two symmetrically distributed semi-annular clamping sleeves approach the external connecting pipe until the semi-annular sealing gasket is hermetically clamped with the outer wall of the external connecting pipe, completing the fixation of the external connecting pipe. The above process can quickly complete the fixation of the external connecting pipe, with a simple structure and convenient operation. At the same time, the installation sealing performance of the external connecting pipe is greatly improved through the semi-annular sealing gasket, and an anti-scaling coating is also provided on the outer wall of the semi-annular sealing gasket, which can prevent the semi-annular sealing gasket from scaling and ensure the service life of the semi-annular sealing gasket.

[0009] Furthermore, a screwing handle is provided on the fastening rod on the side opposite to the semi-annular clamping sleeve.

[0010] Description: When the fastening rod is rotated, it is convenient to operate through the screwing handle.

[0011] Further, a flow guide plate is provided on the inner wall of the tee main body and at adjacent two openings, and horizontal flow guide grooves are provided on the flow guide plate.

[0012] Description: By providing a flow guide plate on the inner wall of the tee main body and at adjacent two openings, the internal flow channel of the tee main body is improved, making the fluid flow more smoothly and reducing stagnation and deposition, reducing the possibility of scaling of the first sealing ring and the second sealing ring, and ensuring the service life.

[0013] Further, the inner wall of the tee main body at each opening and the outer wall of the external connecting pipe are threadedly connected.

[0014] Description: By defining the threaded connection between the tee main body and the outer wall of the external connecting pipe, on the basis of using the sealing and anti-scaling assembly connection, the connection reliability between the tee main body and the external connecting pipe can be further improved.

[0015] The beneficial effects of the present utility model:

[0016] The stainless steel lined tee for preventing scaling of the sealing ring of the present utility model uses an annular clamping sleeve to clamp and fix the external connecting pipe, and increases the sealing performance at the joint through the first sealing ring and the second sealing ring, which can improve the overall sealing performance of the tee, reduce the possibility of leakage, and also help prevent external pollutants from entering the tee interior. Through the sealing clamping ring provided on the clamping cylinder and inclined towards the external connecting pipe, fluid can be prevented from entering between the clamping cylinder and the tee main body, avoiding contact between the first sealing ring and the fluid, reducing the probability of scaling.

Specific embodiments

[0023] Embodiment 1

[0024] As Figure 1 、 2 shown, a stainless steel-lined tee for preventing scale formation on the sealing ring includes a tee main body 1, an external connecting pipe 2 connected to the tee main body 1, and a sealing and scale prevention component 3 provided at the connection between the external connecting pipe 2 and the tee main body 1;

[0025] The sealing and scale prevention component 3 includes a clamping cylinder 30 connected to each internal opening of the tee main body 1 through an annular connecting sleeve 300, a first sealing ring 31 provided between the clamping cylinder 30 and the tee main body 1, an annular clamping sleeve 32 provided at the external opening of the tee main body 1, and a second sealing ring 33 provided inside the annular clamping sleeve 32. An anti-scale coating 34 is provided on the outside of the first sealing ring 31 and the second sealing ring 33. A sealing clamping ring 301 is provided on the side of the clamping cylinder 30 opposite to the annular connecting sleeve 300. Among them, the anti-scale coating 34 is made of PTFE material to reduce the adhesion of scale and improve corrosion resistance and wear resistance. Among them, the materials of the first sealing ring 31 and the second sealing ring 33 are tetrapropylene fluoride rubber;

[0026] As Figure 3 、 4As shown in the figure, two semi-circular clamping sleeves 320 are symmetrically arranged on the inner wall of the annular clamping sleeve 32. The second sealing ring 33 is composed of two semi-circular gaskets 330 respectively arranged on the semi-circular clamping sleeves 320, and the material of the semi-circular gasket 330 is polytetrafluoroethylene. The outer wall of the annular clamping sleeve 32 is threadedly connected with fastening rods 321 that penetrate into the annular clamping sleeve 32 and are connected to the semi-circular clamping sleeves 320 one by one. When using the annular clamping sleeve 32 to clamp and fix the external connecting pipe 2, the external connecting pipe 2 is inserted into the annular clamping sleeve 32, and the fastening rods 321 are manually screwed, so that the two symmetrically distributed semi-circular clamping sleeves 320 move closer to the external connecting pipe 2 until the semi-circular gasket 330 is hermetically clamped with the outer wall of the external connecting pipe 2, completing the fixation of the external connecting pipe 2. The above process can quickly complete the fixation of the external connecting pipe, with a simple structure and convenient operation. At the same time, the installation tightness of the external connecting pipe 2 is greatly improved through the semi-circular gasket 330, and an anti-scaling coating 34 is also provided on the outer wall of the semi-circular gasket 330, which can prevent the semi-circular gasket 330 from scaling and ensure the service life of the semi-circular gasket 330;

[0027] A screwing handle 322 is provided on the side of the fastening rod 321 opposite to the semi-circular clamping sleeve 320. When the fastening rod 321 is rotated, the operation is facilitated through the screwing handle 322;

[0028] As Figure 5 As shown in the figure, flow guiding plates 10 are provided on the inner wall of the tee main body 1 and at adjacent two openings. Horizontal flow guiding grooves 11 are provided on the flow guiding plates 10. By providing the flow guiding plates 10 on the inner wall of the tee main body 1 and at adjacent two openings, the internal flow channel of the tee main body 1 is improved, making the fluid flow more smoothly and reducing stagnation and sedimentation, reducing the possibility of scaling of the first sealing ring 31 and the second sealing ring 33, and ensuring the service life;

[0029] The inner wall of the tee main body 1 at each opening and the outer wall of the external connecting pipe 2 are threadedly connected. By defining the threaded connection between the tee main body 1 and the outer wall of the external connecting pipe 2, on the basis of using the sealing and anti-scaling assembly 3 for connection, the connection reliability between the tee main body 1 and the external connecting pipe 2 can be further improved.

[0030] A method for using a stainless steel-lined tee for preventing scaling of the sealing ring according to this embodiment includes the following steps:

[0031] S1. Insert the external connecting pipe 2 into one of the openings of the tee main body 1, so that the external connecting pipe 2 is inserted between the clamping cylinder 30 and the tee main body 1. At the same time, the end of the external connecting pipe 2 abuts against the first sealing ring 31;

[0032] S2. Manually screw the fastening rod 321 by turning the handle 322, so that the two symmetrically distributed semi-circular clamping sleeves 320 move closer to the external connecting pipe 2 until the semi-circular gasket 330 is hermetically clamped to the outer wall of the external connecting pipe 2, completing the fixation of the external connecting pipe 2.

[0033] S3. Repeat step S1 and step S2 to fixedly install the external connecting pipe 2 at the other two openings of the tee body 1.

[0034] S4. After installation, when the fluid flows into the tee body 1 through the external connecting pipe 2, since the sealing clamping ring 301 inclined towards the external connecting pipe 2 is provided on the clamping cylinder 30, it can prevent the fluid from entering between the clamping cylinder 30 and the tee body 1. At the same time, by arranging the flow guiding plates 10 on the inner wall of the tee body 1 and at the adjacent two openings, the internal flow channel of the tee body 1 is improved, making the fluid flow more smoothly and reducing stagnation and sedimentation, and finally flowing out.
