Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline connecting valve. Background Art

[0002] Pipeline connection valves are devices used to control the flow of fluids (such as liquids, gases or steam) in pipeline systems. They are an important part of the pipeline system, and they regulate the flow, pressure or direction in the pipeline by opening, closing or partially opening. Valves are usually installed on pipelines to cut off, connect or regulate the flow of media to meet the needs of the process system. There are many types of pipeline connection valves, including stop valves: a commonly used cut-off valve that can also be used for throttling. Its opening and closing parts are plug-shaped valve discs, with a flat or conical sealing surface, and the valve disc moves linearly along the center line of the fluid; ball valves: a valve that uses a sphere with a circular through hole as an opening and closing part, and the sphere rotates with the valve stem to achieve the opening and closing action. The opening and closing part of the ball valve is a sphere with a hole, which rotates around an axis perpendicular to the channel, thereby achieving the purpose of opening and closing the channel; gate valves: the opening and closing part is a gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled, etc.

[0003] In the prior art, most water valves need to be closed manually by staff during use, which increases the workload of staff at the end of use; therefore, it does not meet the existing needs. In this regard, we propose a pipeline connection valve. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1: This embodiment is intended to promote the solution of the problem in the prior art that most water valves need to be closed manually when they are used, which increases the workload of the staff at the end of use. Figure 1-Figure 5 A pipeline connecting valve includes a connecting pipe 130, a water outlet pipe 110 is fixedly inserted on one side of the connecting pipe 130, a fixing plate 120 is fixedly installed on the side of the water outlet pipe 110, a water inlet pipe 150 is fixedly inserted on the other side of the connecting pipe 130, a fixing plate 140 is fixedly installed on the side of the water inlet pipe 150, a mounting pipe 160 is installed in the middle of the connecting pipe 130, a water flow hole 170 is opened in the middle of the mounting pipe 160, a baffle 260 is installed in the middle of the water flow hole 170, and a limiting component 360 is installed on the side of the baffle 260.

[0024] A mounting plate 200 is fixedly installed at the end of the connecting tube 130, a fixing block 370 is installed in the middle of the mounting plate 200, a reinforcing block 380 is fixedly installed on the side of the fixing block 370 through a fixing bolt 190, the reinforcing block 380 is fixedly connected to the mounting tube 160, a disassembly bolt 180 is fixedly installed in the middle of the reinforcing block 380, a snap-fit ​​groove 240 is opened on one side of the mounting tube 160, a rotating shaft 270 is fixedly installed in the middle of the snap-fit ​​groove 240, a baffle 260 is hinged on the side of the rotating shaft 270, and a sealing plate 250 is fixedly connected to the side of the baffle 260.

[0025] When the valve is used, water flow 350 flows in from the water inlet pipe 150 and then flows through the installation pipe 160. When the water flow 350 flows into the installation pipe 160, the water flow 350 will impact the baffle 260. At this time, the impact force of the water flow 350 will push the baffle 260, so that the baffle 260 and the slot 210 are misaligned. When the baffle 260 is pushed, due to the setting of the rotating shaft 280 and the fixed shaft 340, the limit assembly 360 will rotate. During the rotation process, the push rod 330 will telescope and move in the middle of the connecting rod 290. Since the push block 320 is set to a rubber block, when it is subjected to a large impact force, the push block 320 will buffer, thereby protecting the baffle 260.

[0026] When the valve is not in use, the impact force pushes the limit assembly 360 to expand and contract, and the spring 310 will be squeezed during the expansion and contraction process. When there is no impact force, the spring 310 will release the elastic force, so that the push rod 330 and the connecting rod 290 are reset. Through the setting of the rotating shaft 270, the baffle 260 will also be reset. During the resetting process, the baffle 260 will be engaged with the slot 210, and the sealing plate 250 will seal the connection to avoid the backflow of water 350 as much as possible.

[0027] In this embodiment: when the valve is in use, water flow 350 will flow in from the water inlet pipe 150, and then flow through the connecting pipe 130. When flowing through the mounting pipe 160, it will flow into the mounting pipe 160 from the water flow hole 170. The impact force of the water flow 350 will open the baffle 260. When the baffle 260 is opened, the water flow 350 will flow out. When the baffle 260 is opened, the limit assembly 360 will retract and retract. When the water flow 350 stops, due to the lack of impact force, the limit assembly 360 will push the baffle 260. At the same time, due to the setting of the rotating shaft 270, the baffle 260 itself will also rotate, and then the baffle 260 will engage with the slot 210, so that the valve can be automatically closed when not in use, thereby reflecting the convenience of the valve.

[0028] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that when the water flow 350 flows through, it has a large impact force. If the automatic water blocking baffle 260 in the middle of the water valve is not protected, it will be easily damaged by the large impact force. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 5 A slot 210 is provided on the other side of the mounting tube 160 , one side of the slot 210 is connected to an arc groove 220 , and a stopper 230 is fixedly connected to the other side of the slot 210 . The stopper 230 and the sealing plate 250 are both made of rubber.

[0029] The limiting assembly 360 includes a rotating shaft 280 fixedly installed on the side of the baffle 260, a connecting rod 290 is hinged on the side of the rotating shaft 280, a limiting groove 300 is opened in the middle of the connecting rod 290, a spring 310 is installed in the middle of the limiting groove 300, one end of the spring 310 is fixedly connected to the inner wall of the limiting groove 300, and the other end of the spring 310 is fixedly connected to the push block 320.

[0030] The push block 320 moves in the middle of the limiting groove 300, and a push rod 330 is fixedly connected to the side of the push block 320. The push rod 330 is inserted in the middle of the limiting groove 300. A fixed shaft 340 is hinged at the end of the push rod 330. The fixed shaft 340 is fixedly installed on the side of the mounting tube 160. Water flow 350 flows in the middle of the water hole 170. The water flow 350 impacts the baffle 260, and the water flow 350 contacts the baffle 260. The baffle 260 is in contact and connected with the block 230.

[0031] In this embodiment: when the baffle 260 is opened, the rotating shaft 280 and the fixed shaft 340 in the limit assembly 360 will drive the connecting rod 290 to rotate. While rotating, the connecting rod 290 will be pushed, thereby squeezing the spring 310. Through the installation of the limit assembly 360, when subjected to a large impact force, the impact force of the water flow 350 is dispersed as much as possible through the extension and contraction of the push rod 330 and the setting of the push block 320, thereby protecting the baffle 260. Through the setting of the sealing plate 250, when the valve is not in use, the sealing treatment of the sealing plate 250 can avoid the backflow of the water flow 350 as much as possible, thereby improving the safety of the valve.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
