Description

Technical Field

[0001] This patent relates to the technical field of three-way stop valves, specifically an adjustable three-way stop valve. Background Art

[0002] The three-way stop valve is used for diverting pipelines. The three end pipes of the existing three-way stop valve are connected to the pipeline through threaded pipes. However, the threaded pipes will rotate and contact with the rubber rings on the end pipes, which may cause serious wear to the rubber rings. The rubber rings are prone to wrinkles, which affects the sealing effect. In addition, the length of the threaded pipes is relatively single, so they can only be connected to the end pipes of the stop valve of the same length, and the scope of application is relatively small. Therefore, we propose an adjustable three-way stop valve. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This patent provides a technical solution: an adjustable three-way stop valve, including a three-way stop valve body 1 and a connecting pipe, the left and right sides and the bottom of the three-way stop valve body 1 are fixedly installed with end pipes 2, the outer wall of the end pipe 2 is integrally formed with an external thread ring 3, and the outside of the external thread ring 3 is bonded with a rubber ring;

[0022] External threaded rings 3 with rubber rings are arranged on the outer walls of the three external pipes connected to the three end pipes 2 .

[0023] The connecting pipe includes a rubber tube 4, and threaded tubes 5 are installed at both left and right ends of the rubber tube 4;

[0024] The rubber tube 4 is soft and can adapt to the connection distance between the end tube 2 and the external pipe. After the connection is completed, a connecting rod can be welded outside the valve body of the three-way stop valve body 1, and the other end of the connecting rod can be welded to the outer wall of the external pipe to fix the three-way stop valve body 1.

[0025] The threaded tube 5 includes a pressure ring 6 and an internal thread ring 10. The inner side of the pressure ring 6 is fixedly installed on the end of the rubber tube 4. The outer side wall of the pressure ring 6 is provided with an annular groove 7. A circular ring 8 is rotatably installed in the annular groove 7. The shape and size of the circular ring 8 match the internal shape and size of the annular groove 7. A connecting ring 9 is fixedly installed on the outer side wall of the circular ring 8. The end of the connecting ring 9 is fixed to the end of the internal thread ring 10. The inner side wall thread of the internal thread ring 10 matches the outer side wall thread of the external thread ring 3. The internal thread ring 10 is screwed on the outer side wall of the external thread ring 3. The inner end of the pressure ring 6 fits tightly on the rubber ring.

[0026] Limiting pieces are provided on both upper and lower sides of the outer end of the pressing ring 6 , and the pressing ring 6 is connected to the external threaded ring 3 through the limiting pieces.

[0027] Specifically, the limiting member includes a sliding rod 11, the end of which is integrally formed on the outer end of the pressure ring 6, and sliding holes 12 are provided on the upper and lower sides of the outer side surface of the external threaded ring 3. The diameter of the sliding rod 11 matches the diameter of the sliding hole 12, and the side wall of the sliding rod 11 and the inner wall of the sliding hole 12 slide relatively.

[0028] The slide rod 11 slides in the slide hole 12 to limit the moving track of the pressure ring 6 so that it can only move left and right and contact the rubber ring on the external thread ring 3 in a stable and straight line.

[0029] Specifically, the inner end of the slide rod 11 exceeds the inner end surface of the internal thread ring 10 .

[0030] Since the inner end of the slide rod 11 exceeds the inner end surface of the internal thread ring 10 , the slide rod 11 can be inserted into the slide hole 12 to first play a limiting role when the internal thread ring 10 is not screwed onto the external thread ring 3 .

[0031] Specifically, the circular ring 8 includes a first half ring 13 and a second half ring 14 , and two ends of the first half ring 13 and the second half ring 14 are opposite to each other.

[0032] By dividing the circular ring 8 into the first half ring 13 and the second half ring 14 , it is convenient to install the circular ring 8 in the annular groove 7 in the early stage.

[0033] Specifically, mounting holes 15 are provided at both ends of the inner side surface of the connecting ring 9, and one end of a screw rod 16 is integrally formed in the middle of the outer side walls of the first half ring 13 and the second half ring 14, and the other end of the screw rod 16 passes through the mounting hole 15 and is screwed with a nut 17, which is pressed tightly against the outer side wall of the connecting ring 9.

[0034] Specifically, both ends of the outer wall of the connecting ring 9 are integrally formed with a spherical surface 18 , a through hole 19 is provided in the middle of the spherical surface 18 , and an inner concave surface 20 is provided on the inner side surface of the nut 17 , and the inner concave surface 20 fits tightly on the spherical surface 18 .

[0035] If the nut 17 is directly tightened, a small portion of the nut 17 is pressed against the outer wall of the connecting ring 9, and the locking force is relatively small. If the inner concave surface 20 is provided to fit closely on the spherical surface 18, the locking force can be increased.

[0036] Working principle: Figure 2 In the process, the sliding rod 11 can be first inserted into the sliding hole 12, and then the internal threaded ring 10 is screwed on the external threaded ring 3 until the inner side of the pressing ring 6 is pressed tightly on the rubber ring on the external threaded ring 3, so that the pressing ring 6 and the rubber ring are in linear and stable contact to avoid rotational contact, thereby ensuring the sealing effect of the rubber ring, and then the threaded tube 5 on the other side of the rubber tube 4 is rotated to connect it to the outer wall of the external pipe. The setting of the rubber tube 4 can adapt to the gap distance between the pipe and the end pipe 2, which is convenient for connecting and using end pipes 2 of different lengths.
