Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a two-way stop valve with a sealing ring. Background Art

[0002] The stop valve is widely used in pipelines in the oil refining, metallurgy, chemical industry, power industry, cities and other industries to control the flow of pipeline media and cut off or adjust them. It is one of the most widely used valves in various fluid transportation projects. The stop valve, also known as the gate valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. However, its disadvantages are also obvious. When closing the valve, the efficiency is low. It is necessary to turn the hand wheel several times before the stop valve can be closed, and the efficiency is low when closing.

[0003] The utility model patent with the authorization announcement number CN214305304U discloses a stop valve, which includes a valve body with an internal passage, a cut-off assembly for cutting off the internal passage of the valve body, and a slide rod, an adjusting column, a sealing part for cutting off the internal passage of the valve body, and a sealing cover, the sealing cover is fixed on the valve body, the adjusting column is threadedly connected with the sealing cover and one end of the adjusting column extends into the interior of the valve body, the middle part of the adjusting column has a slideway, the slide rod is slidably arranged on the slideway and the upper and lower ends of the slide rod both extend out of the slideway, the sealing part is fixed on the lower end of the slide rod, and the lower end of the adjusting column can be pressed on the sealing part. The utility model has the advantage of being able to cut off quickly.

[0004] Although the above utility model can be quickly cut off, there is no sealing rubber ring on the connection surface between the two ends and the pipeline. When installing, it is necessary to manually add the sealing rubber ring in the connection, which is troublesome to install. In view of this, we propose a two-way stop valve with a sealing ring.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , this embodiment provides a technical solution:

[0027] A two-way stop valve with a sealing ring comprises a stop valve 1. Sealing mechanisms 2 are fixedly installed at both left and right ends of the stop valve 1. The sealing mechanism 2 comprises a sealing disk 21, a supporting mechanism 22 slidably connected to the lower side of the inside of the sealing disk 21, and a sealing rubber ring 23 placed on the upper side of the supporting mechanism 22. Through the above mechanism, the sealing rubber ring 23 can be conveniently placed in the connection between the stop valve 1 and the pipeline, which facilitates the installation of the stop valve 1.

[0028] Furthermore, a plurality of connection holes 211 are provided on the side surface of the sealing disk 21 , a mounting groove 212 is provided on the lower side of the inner surface of the sealing disk 21 , a limiting groove 213 is provided on the rear surface of the mounting groove 212 , and the limiting groove 213 is located in the middle position of the rear surface of the mounting groove 212 .

[0029] Furthermore, the support mechanism 22 includes a support block 221, a support rod 222 welded to the middle position of the right side surface of the support block 221, and a support plate 223 welded to the right end of the support rod 222. A spring 224 is welded to the right side surface of the support plate 223, and an auxiliary block 225 is connected to the right side of the spring 224. The position of the support block 221 is controlled by the spring 224.

[0030] In this embodiment, there are six connection holes 211 , which are distributed in a circular shape at equal angles to increase connection stability.

[0031] In this embodiment, the depth of the installation groove 212 is less than the thickness of the sealing disk 21 , and the size of the installation groove 212 is equal to one quarter of the sealing disk 21 , ensuring that the support block 221 in the installation groove 212 can provide effective support for the sealing rubber ring 23 .

[0032] In this embodiment, the support block 221 is slidably connected in the installation groove 212, and the support rod 222 is slidably connected in the limiting groove 213. The support block 221 is controlled to move in the installation groove 212 by sliding the support rod 222 in the limiting groove 213.

[0033] In this embodiment, the thickness of the left end of the support block 221 is greater than that of the right end, the size of the left surface of the support block 221 is consistent with the size of the installation groove 212, and the upper surface of the support block 221 is inclined toward the inside of the installation groove 212, so that the sealing rubber ring 23 can fit the side surface of the sealing disk 21.

[0034] In this embodiment, the auxiliary block 225 is welded to the lower surface of the stop valve 1. When no external force is applied, the spring 224 is in a compressed state and pushes the support plate 223 toward the sealing disk 21. When no external force is applied, the spring 224 pushes the support block 221 out of the installation groove 212, so that the sealing rubber ring 23 can be placed.

[0035] It is worth mentioning that the structure and working principle of the stop valve 1 involved in this embodiment are well known to those skilled in the art and will not be elaborated herein.

[0036] During the specific use of the two-way stop valve with a sealing ring in this embodiment, first, under the action of the spring 224, the support sheet 223 is pushed toward the sealing disk 21, so that the support rod 222 is pushed outward until the support sheet 223 contacts the side surface of the sealing disk 21. At this time, the support block 221 partially leaves the installation groove 212, so that the sealing rubber ring 23 can be placed on the upper side of the support block 221. The support block 221 supports the sealing rubber ring 23, so that the stop valve 1 can be conveniently connected to the pipeline, and as the two are tightly connected, the pipeline will push the support block 221 back into the installation groove 212 until the installation is completed.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
