Description

Technical Field

[0001] This invention relates to the field of valves, specifically to an ultra-high temperature three-way ball valve. Background Technology

[0002] Existing ball valves operate in ultra-high temperature environments of 875℃, and cooling structures are generally installed to reduce their temperature. Current technical solutions typically involve installing a water-cooling structure on the outer wall of the valve body, while the internal ball is usually made of high-temperature resistant materials. This approach is expensive, has poor cooling effect, and can cause internal components to jam. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an ultra-high temperature three-way ball valve that is cost-effective, safe, and easy to operate.

[0004] The technical solution adopted in this invention is as follows: an ultra-high temperature three-way ball valve, comprising a valve cover, a valve body mechanism, a valve stem, a ball mechanism, and a valve seat mechanism. A valve stem seat is provided between the ball mechanism and the valve stem for linkage connection. A cavity is provided between the valve stem, the valve stem seat, and the ball mechanism. Several annular channels are provided within the ball mechanism. A transfer channel is provided between the cavity and the annular channels, connecting the two. A connecting assembly is provided on the inner wall of the valve body mechanism to rotatably seal against the valve stem seat. An inlet channel and an outlet channel are provided within the valve body mechanism and the connecting assembly. The inlet channel passes through the valve stem seat and communicates with the annular channel in the ball mechanism. The outlet channel passes through the valve stem and the valve stem seat and communicates with the cavity.

[0005] The connecting assembly includes a fixed connecting clamp and a guide frame. The guide frame is fixedly installed on the inner wall of the valve body mechanism, and the clamp is sealed to the outer circumference of the valve stem seat and rotates in fit.

[0006] The spherical mechanism includes an inner sphere and an outer spherical sleeve. The inner wall of the outer spherical sleeve is provided with a first annular groove, which cooperates with the outer wall of the inner sphere to form the annular channel. A partition is provided in the first annular groove. The outer spherical sleeve is provided with an inlet and an outlet on both sides of the partition, which are connected to the first annular groove.

[0007] The outer circumferential surface of the valve stem seat is provided with a second annular groove, and the valve stem seat is provided with a first transition hole corresponding to the water inlet and the second annular groove. The water inlet channel, the second annular groove, the first transition hole and the water inlet are connected in sequence.

[0008] The valve stem seat is provided with a second transition hole, which is connected to the outlet and forms a transfer channel.

[0009] The bottom end of the valve stem is provided with a third transition hole that connects to the cavity. The valve stem seat is also provided with a fourth transition hole. The outer circumferential surface of the valve stem seat is also provided with a third annular groove. The third transition hole, the fourth transition hole, the third annular groove, and the water outlet channel are connected in sequence.

[0010] The water inlet channel includes a first channel penetrating the inner and outer walls of the clamp, a second channel disposed within the guide frame, and a third channel disposed within the valve body mechanism, wherein the first channel, the second channel, and the third channel are connected in sequence. The water outlet channel includes a fourth channel that penetrates the inner and outer walls of the clamp, a fifth channel that is located in the guide frame, and a sixth channel that is located in the valve body mechanism. The fourth, fifth, and sixth channels are connected in sequence.

[0011] The valve stem seat is fitted with the valve stem, and the bottom end of the valve stem and the inner hole of the valve stem seat are both polygonal in cross-section. A sealing ring is provided between the valve stem and the valve stem seat.

[0012] Sealing rings are provided on the upper and lower sides of the second and third annular grooves, respectively. The beneficial effects of this invention are: cooling water enters the annular channel in the spherical mechanism through the water inlet channel, carries away the heat of the spherical mechanism, then enters the cavity, and finally exits through the water outlet channel. The spherical mechanism does not require expensive high-temperature resistant materials and can use ordinary materials. It prevents internal parts from getting stuck and has the advantages of cost saving, good safety, and safe operation. Attached Figure Description

[0028] The embodiments of the present invention will be further described below with reference to the accompanying drawings: As shown in the figure, an ultra-high temperature three-way ball valve includes a valve cover 1, a valve body mechanism 2, a valve stem 4, a ball mechanism 5, and a valve seat mechanism 3. A valve stem seat 41 is provided between the ball mechanism 5 and the valve stem 4 for linkage connection. A cavity 7 is provided between the valve stem 4, the valve stem seat 41, and the ball mechanism 5. The ball mechanism 5 has several annular channels 51. A transfer channel 54 connects the cavity 7 and the annular channels 51. The inner wall of the valve body mechanism 2 is provided with a connecting assembly that rotates and seals with the valve stem seat 41. The valve body mechanism 2 and the connecting assembly contain... The water inlet channel 43 and the water outlet channel 44 are provided. The water inlet channel 43 passes through the valve stem seat 41 and connects to the annular channel 51 in the ball mechanism 5. The water outlet channel 44 passes through the valve stem 4 and the valve stem seat 41 and connects to the cavity 7. In this embodiment, cooling water enters the annular channel in the ball mechanism through the water inlet channel, carries away the heat of the ball mechanism, then enters the cavity, and finally exits through the water outlet channel. The ball mechanism does not require expensive high-temperature resistant materials; ordinary materials can be used. This prevents internal parts from getting stuck and has the advantages of cost saving, good safety, and safe operation.

[0029] The connecting assembly includes a fixed connecting clamp 42 and a guide frame 45. The guide frame 45 is fixedly installed on the inner wall of the valve body mechanism 2. The clamp 42 is circumferentially sealed and rotatably engaged with the outer circumference of the valve stem seat 41. The inner wall of the clamp wraps around the circumferential outer wall of the valve stem seat, and the two rotate relative to each other.

[0030] The spherical mechanism 5 includes an inner sphere 52 and an outer spherical sleeve 53. The inner wall of the outer spherical sleeve 53 is provided with a first annular groove 531, which cooperates with the outer wall of the inner sphere 52 to form the annular channel 51. A partition 532 is provided in the first annular groove 531. The outer spherical sleeve 53 is provided with an inlet 533 and an outlet 534 on both sides of the partition 532, which communicate with the first annular groove 531. In order to realize the annular channel in the sphere, the other parts need to be set as a split structure for easy processing. In addition, by setting the partition, it can be ensured that the cooling water entering through the inlet must first circle the annular channel before being discharged from the outlet, effectively ensuring that the cooling water can carry away the heat of all parts.

[0031] The outer circumferential surface of the valve stem seat 41 is provided with a second annular groove 411, and the valve stem seat 41 is provided with a first transition hole 412 corresponding to the water inlet 533 and the second annular groove 411. The water inlet channel 43, the second annular groove 411, the first transition hole 412 and the water inlet 533 are connected in sequence. Because the valve stem seat and the clamp rotate relative to each other, it is necessary to provide a second annular groove to ensure that the cooling water in the water inlet channel can smoothly enter the first transition hole.

[0032] The valve stem seat 41 is provided with a second transition hole 413. The second transition hole 413 and the water outlet 534 are interconnected and form a transfer channel 54. The cooling water in the annular channel is discharged into the cavity through the transfer channel.

[0033] The bottom end of the valve stem 4 is provided with a third transition hole 46 that connects to the cavity 7. The valve stem seat 41 is also provided with a fourth transition hole 414. The outer circumferential surface of the valve stem seat 41 is also provided with a third annular groove 415. The third transition hole 46, the fourth transition hole 414, the third annular groove 415 and the water outlet channel 44 are connected in sequence. The third annular groove is provided to ensure that the cooling water in the cavity can smoothly enter the water outlet channel.

[0034] The water inlet channel 43 includes a first channel 431 that penetrates the inner and outer walls of the clamp 42, a second channel 432 that is disposed in the guide frame 45, and a third channel 433 that is disposed in the valve body mechanism 2. The first channel 431, the second channel 432, and the third channel 433 are connected in sequence. The water outlet channel 44 includes a fourth channel 434 that penetrates the inner and outer walls of the clamp 42, a fifth channel 435 that is installed in the guide frame 45, and a sixth channel 436 that is installed in the valve body mechanism 2. The fourth channel 434, the fifth channel 435, and the sixth channel 436 are connected in sequence.

[0035] The valve stem seat 41 is fitted with the valve stem 4. The bottom end of the valve stem 4 and the cross-section of the inner hole of the valve stem seat 41 are both polygonal. A sealing ring is provided between the valve stem 4 and the valve stem seat 41 to provide sealing performance.

[0036] Sealing rings are provided on the upper and lower sides of the second annular groove 411 and the third annular groove 415 respectively. The ball and valve stem have one inlet and one outlet, with a flow channel diameter of 15mm and a water intake rate of 31.8 liters per minute.

[0037] Steel quality calculation: The total weight of the steel used in the valve body's three inlet flow channels and the central cavity flow channel is 962 kg; the weight of the steel used in the ball and valve stem is 242 kg. Heat absorption calculation: A. Calculation of heat absorption by cooling water and steel in the three inlet channels and the cooling channel in the middle cavity of the valve body: ①Q 水 =C 水 m 水 (t - t0) = 4.2 × 10 3 ×95.4×(400-800)=-160.0×106 (joules); ②Q 铁 =C 铁 .m 铁 (t-t0) = 0.46 × 10³ × 96² × (400-800) = -177 × 10⁶ (joules); B. Calculation of heat absorption by the ball, valve stem cooling water, and steel: ①Q 水 =C 水 m 水 (t- t0) =4.2×10³×31.8×(100-400) =-40×106 (joules); ②Q 铁 =C 铁 .m 铁 (t- t0) =0.46×10³×24²×(100-400) = -33.4 × 10⁶ (joules). The valve body mechanism 2 has an inlet 91, an outlet 92, a side outlet 93, and a central cavity 94 connected to the valve cover 1. The valve body mechanism 2 has a first cooling channel 25 with a first water inlet 251 at the inlet 91, a second cooling channel 26 with a second water inlet 261 at the outlet 92, and a third cooling channel 27 with a third water inlet 271 at the side outlet 93.

The system includes a fourth cooling channel 28 that connects the first cooling channel 25, the second cooling channel 26, and the third cooling channel 27, and has a fourth water outlet 281. This technical solution involves setting up the first, second, and third cooling channels, circulating cooling water through them, and then having the cooling water in the three channels carry away the heat and concentrate in the fourth cooling channel before finally being discharged from the fourth water outlet. This structure does not require expensive high-temperature resistant materials; ordinary materials can be used. It also prevents internal components from getting stuck, and has the advantages of cost savings, good safety, and safe operation.

[0038] The valve body mechanism 2 includes a valve body 29, a first inner sleeve 21 installed at the inlet 91 position of the valve body 29, a second inner sleeve 22 installed at the outlet 92 position of the valve body 29, a third inner sleeve 23 installed at the side outlet 93 position of the valve body 29, and a fourth inner sleeve 24 installed at the middle cavity 94 position of the valve body 29.

As shown in the figure, the outer wall of the first inner sleeve is machined with a spiral first cooling groove, and then it is installed into the valve body. The first inner sleeve and the valve body are sealed together, and the first cooling groove and the valve body cooperate to form a first cooling channel 25. In addition, after the first inner sleeve is installed on the valve body, its end face is fastened with bolts. The second inner sleeve, the third inner sleeve and the fourth inner sleeve are installed on the same principle.

A first sealing ring 311 and a disc spring 312 are provided between the first inner sleeve 21 and the inlet valve seat 31. The disc spring provides elastic preload to the inlet valve seat, and the first sealing ring ensures the sealing between the first inner sleeve 21 and the inlet valve seat 31.

[0040] The valve seat mechanism 3 also includes an outlet valve seat 32 corresponding to the outlet section 92. The outlet valve seat 32 is coaxially mounted on the inner wall of the valve body 29 at the outlet section 92 and located in front of the second inner sleeve 22. A second sealing ring 321 is provided between the second inner sleeve 22 and the outlet valve seat 32 to improve the sealing performance.

[0041] The inner wall of the third inner sleeve 23 is provided with a side outlet valve seat 33, a pressure sleeve 34 and an adjusting sleeve 35 installed coaxially in sequence. A third sealing ring 331 is provided between the side outlet valve seat 33 and the pressure sleeve 34. The pressure sleeve 34 and the adjusting sleeve 35 are connected by a threaded fit. The end of the adjusting sleeve 35 contacts the valve body 29 and a stop pin 36 is provided between the two. The pressure sleeve and the side outlet valve seat cooperate to compress the third sealing ring. After the adjusting sleeve is tightened, the stop pin is inserted. This structure can adjust the sealing performance of the side outlet valve seat.

[0042] The valve body 29 is provided with a first transition channel 291 connecting the first cooling channel 25 and the fourth cooling channel 28, and a second transition channel 292 connecting the second cooling channel 26 and the fourth cooling channel 28. The third inner sleeve 23 and the fourth inner sleeve 24 are each provided with a second through hole 231, and the two second through holes 231 cooperate to form a third transition channel connecting the third cooling channel 27 and the fourth cooling channel 28.
