Description

Technical Field

[0001] The present application relates to the technical field of right-angle stop valves, and in particular to a high-sealing right-angle stop valve. Background Art

[0002] The right angle stop valve is a type of stop valve. Its working principle is to control the flow of the medium by rotating the valve. In the right angle stop valve, the valve has a rotation angle of 90 degrees, and the flow of the medium in the pipeline is controlled by changing the rotation angle of the valve. When the valve is in the closed state, the medium cannot pass through the valve, thus achieving the cut-off work. The characteristic of this valve is that its inlet and outlet are at a 90-degree angle, that is, the direction of the liquid flowing into the valve and the direction of the liquid flowing out of the valve are at a 90-degree angle.

[0003] The existing Chinese patent with publication number CN220337498U discloses a right-angle stop valve, including a first pipeline and a connecting mechanism arranged above the first pipeline, the connecting mechanism including a mounting assembly and a positioning assembly; the mounting assembly includes a first flange ring, a connecting shaft, a mounting bracket, a first threaded shaft, a clamping block, a first telescopic sleeve, a clamping groove and a second flange ring, the upper end of the first pipeline is fixedly connected with the first flange ring, the side wall of the first flange ring is installed with a connecting shaft, the outer surface of the connecting shaft is installed with a mounting bracket, the interior of the mounting bracket is installed with a first threaded shaft, the lower end of the first threaded shaft is installed with a clamping block, the upper end surface of the clamping block is fixedly connected with the first telescopic sleeve, the upper end surface of the first flange ring is installed with a second flange ring, and the surface of the second flange ring is provided with a clamping groove; the positioning assembly includes a positioning groove and a positioning bolt, the inner wall of the second flange ring is installed with a positioning groove, and the inner wall of the first flange ring is installed with a positioning bolt.

[0004] The above-mentioned right-angle stop valve is provided with a clamping block, and the provided mounting bracket can be rotated to a certain extent with the first flange ring through the connecting shaft, and then the installed first threaded shaft is rotated, so as to facilitate the lifting and lowering adjustment of the clamping block along the first telescopic sleeve inside the mounting bracket, and then the clamping block can be clamped and connected with the second flange ring through the clamping groove, so as to facilitate the clamping connection of the first flange ring and the second flange ring, and avoid the loosening of the bolts when the first flange ring and the second flange ring are installed by bolts during long-term use, resulting in poor sealing of the equipment. However, the above-mentioned right-angle stop valve still has some disadvantages, such as: the first flange ring and the second flange ring are connected by the cooperation of the clamping block and the clamping groove, and there is a gap between the first flange ring and the second flange ring, and the sealing between the first flange ring and the second flange ring cannot be guaranteed, which needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a high-sealing right-angle stop valve in order to improve the sealing between the first flange ring and the second flange ring.

[0006] A high-sealing right-angle stop valve provided in the present application adopts the following technical solution: it includes a valve body, the valve body is detachably connected to a valve cover, the valve body is connected to a first flange ring, the valve cover is connected to a second flange ring, the first flange ring and the second flange ring are connected by a fixing component, a sealing ring is connected between the first flange ring and the second flange ring, the sealing ring surrounds the opening of the valve body, and the sealing ring abuts against the first flange ring and the second flange ring.

[0007] By adopting the above technical solution, the sealing ring is used to seal the gap between the first flange ring and the second flange ring, thereby preventing liquid from leaking from the gap between the first flange ring and the second flange ring, thereby improving the sealing between the first flange ring and the second flange ring.

[0008] Optionally, both the first flange ring and the second flange ring are provided with mounting grooves for cooperating with the sealing ring.

[0009] By adopting the above technical solution, the sealing ring is inserted into the installation groove, and the outer surface of the sealing ring is in contact with the inner wall of the installation groove. The inner wall of the installation groove restricts the movement of the sealing ring, thereby improving the stability of the sealing ring placement. The sealing ring cooperates with the installation groove to increase the path of liquid flow and reduce the occurrence of leakage, thereby improving the sealing between the first flange ring and the second flange ring.

[0010] Optionally, the sealing ring is connected to two ring blocks, and the first flange ring and the second flange ring are provided with ring grooves for matching with the corresponding ring blocks, and the ring grooves are communicated with the mounting grooves.

[0011] By adopting the above technical solution, the cooperation between the ring block and the ring groove increases the path for liquid flow, reduces the occurrence of leakage, and thus improves the sealing between the first flange ring and the second flange ring.

[0012] Optionally, there are at least two sealing rings, and one of the sealing rings surrounds the other sealing ring.

[0013] By adopting the above technical solution, when one of the sealing rings is damaged due to aging, the remaining sealing rings can still play a sealing role. Multiple sealing rings provide multiple protections, thereby improving the sealing between the first flange ring and the second flange ring.

[0014] Optionally, the first flange ring is rotatably connected to a connecting plate, and the fixing assembly includes a fixing block slidably connected to the connecting plate and an active structure for driving the fixing block to move closer to or away from the second flange ring, the active structure is connected to the connecting plate, and the second flange ring is provided with a fixing groove for cooperating with the fixing block.

[0015] By adopting the above technical solution, the connecting plate is rotated to provide space for the first flange ring and the second flange ring to fit together. After the first flange ring and the second flange ring are fitted together, the connecting plate is rotated in opposite directions so that the fixing block corresponds to the fixing groove, and the active structure drives the fixing block to slide in the direction close to the second flange ring, so that the fixing block is stuck in the fixing groove, and the fixing block applies force on the second flange ring, and the second flange ring is clamped by the first flange ring and the fixing block, thereby improving the installation stability between the first flange ring and the second flange ring.

[0016] Optionally, the active structure includes a threaded rod threadedly connected to the connecting plate, the threaded rod is used to abut against the fixed block, the fixed block and the connecting plate are connected by an elastic member, one end of the elastic member is connected to the connecting plate, and the other end is connected to the fixed block.

[0017] By adopting the above technical solution, when fixing the first flange ring and the second flange ring, the threaded rod is rotated in the direction close to the fixed block, the threaded rod abuts against the fixed block and drives the fixed block to move in the direction close to the second flange ring, so that the fixed block abuts against the inner wall of the fixed groove, and the elastic member is elastically deformed and elongated under tension. When loosening the first flange ring and the second flange ring, the threaded rod is rotated in the direction away from the fixed block, the elastic member is elastically reset, and the elastic member forces the fixed block to slide in the direction close to the threaded rod, so that the fixed block loosens the second flange ring, which is convenient for separating the valve body and the valve cover.

[0018] Optionally, the fixing block is connected to a guide column, and the connecting plate is provided with a guide hole for slidingly cooperating with the guide column.

[0019] By adopting the above technical solution, when the fixed block slides, the sliding cooperation between the guide column and the guide hole plays a guiding and limiting role in the sliding of the fixed block, thereby improving the sliding stability of the fixed block.

[0020] Optionally, the first flange ring and the second flange ring are connected via a plurality of locking members.

[0021] By adopting the above technical solution, the locking member is used to lock the first flange ring and the second flange ring, thereby improving the installation stability between the first flange ring and the second flange ring.

[0022] Optionally, the second flange ring is connected to a convex ring, the first flange ring is provided with a groove for the convex ring to be snapped into, the inner wall of the groove is connected to a positioning block, and the convex ring is provided with a positioning groove for the positioning block to be snapped into.

[0023] By adopting the above technical solution, the positioning block is inserted into the positioning groove, and the outer surface of the positioning block fits with the inner wall of the positioning groove. The positioning block limits the rotation of the convex ring, thereby improving the stability between the first flange ring and the second flange ring.

[0024] Optionally, the valve cover is threadedly connected to a valve stem, the valve stem is connected to a baffle, the baffle is used to seal the water inlet of the valve body, and the valve body is provided with a baffle groove for the baffle to be inserted into.

[0025] By adopting the above technical solution, the valve stem is rotated toward the direction close to the retaining groove, and the valve stem drives the baffle plate to move toward the direction close to the retaining groove, so that the baffle plate is stuck in the retaining groove, thereby the valve has the effect of closing.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The sealing ring is used to seal the gap between the first flange ring and the second flange ring, thereby preventing liquid from leaking from the gap between the first flange ring and the second flange ring, thereby improving the sealing between the first flange ring and the second flange ring.

[0028] 2. The cooperation between the ring block and the ring groove increases the path for liquid flow and reduces the occurrence of leakage, thereby improving the sealing between the first flange ring and the second flange ring. BRIEF DESCRIPTION OF THE DRAWINGS
