[0002] Y-type stop valve is suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with nominal pressure PN1.6~6.4Mpa and working temperature -29~550℃ to cut off or connect the medium. Applicable media are: water, oil, steam, acidic media, etc. The operation modes are: manual and pneumatic. Y-type stop valve is the most widely used valve. The reason why it is so popular is that the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to rely on the valve stem pressure to make the valve disc sealing surface and the valve seat sealing surface fit closely to prevent the flow of the medium.

[0003] The patent name is "A Y-type stop valve" with the publication number "CN208919449U". When the device in the public document closes the sealing gasket, the impact force of the liquid flow rate inside the pipeline makes the sealing gasket unable to move smoothly along the longitudinal direction of the pipeline. The staff needs to increase the force of rotating the hand wheel to ensure that the sealing gasket blocks the liquid inside the pipeline. This operation method is time-consuming and labor-intensive. In addition, when the sealing gasket blocks the liquid, the liquid cannot be in a diverting state, resulting in excessive impact force of the liquid on the sealing gasket. Over time, the sealing gasket is damaged, reducing the service life of the sealing gasket. Based on this, the utility model designs a high-performance Y-type integral forged stop valve to solve the above problems. Utility Model Content

[0024] 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 of 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. Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the device includes a Y-shaped tube 1, a mounting plate 2 and a drainage hole 3. The mounting plate 2 is fixedly arranged on the right side of the Y-shaped tube 1, and the drainage hole 3 is integrally arranged inside the mounting plate 2. A blocking component 4 is arranged at the upper end of the Y-shaped tube 1. The blocking component 4 includes a guide groove 401 integrally arranged on the left and right sides of the upper end of the Y-shaped tube 1. A slider 402 is slidably connected inside the guide groove 401, and a blocking block 403 is fixed between the two sliders 402. A connecting sleeve 404 made of metal is fixedly arranged at the middle end of the blocking block 403. A connecting rod 405 with a threaded arrangement inside the connecting sleeve 404 rotates and passes through the upper end of the Y-shaped tube 1. Connecting pins 406 are fixedly arranged on the left and right sides of the bottom of the blocking block 403. A blocking plate 407 is fixedly arranged at one end of the connecting pin 406 away from the blocking block 403, and a guide hole 408 is integrally arranged inside the blocking plate 407.

[0026] The drainage hole 3 and the guide hole 408 are both through-hole designs, and the cross section of the guide hole 408 is L-shaped. The blocking block 403 and the blocking plate 407 are made of rubber. First, the liquid is discharged from the left end of the Y-tube 1 through the drainage hole 3 and the right end of the Y-tube 1. When the staff needs to seal the inside of the Y-tube 1, the staff rotates the connecting rod 405 forward, and through the threaded transmission of the connecting rod 405 and the connecting sleeve 404, the connecting sleeve 404 drives the blocking block 403 together with the connecting pin 406, the blocking plate 407 and the slider 402 to move along the direction of the guide groove 401, that is, the blocking plate 407 moves along the direction of the mounting plate 2. At this time, the liquid moves from left to right through the diversion effect of the guide hole 408, so that part of the liquid flows back from the guide hole 408 to the left side of the inside of the Y-tube 1. In the above manner, the impact force of the liquid on the moving blocking plate 407 is reduced, so that the blocking plate 407 can be smoothly and tightly fitted with the mounting plate 2, so that the blocking plate 407 can conveniently block the drainage hole 3. In addition, when the staff needs to connect the inside of the Y-tube 1, they only need to reverse the connecting rod 405, and the operation method is opposite to the above, so that the space between the sealing plate 407 and the mounting plate 2 is expanded, and the liquid can be discharged from the right side of the Y-tube 1 through the left side of the Y-tube 1. Example 2

[0027] like Figure 2 , Figure 4 , Figure 7 As shown, a circular plate 5 is fixedly sleeved on the upper end of the outer portion of the connecting rod 405, and a latch 6 is threadedly penetrated through the right side of the top of the circular plate 5. The axis of the latch 6 is designed to be parallel to the axis of the connecting rod 405. A plurality of sockets 7 are integrally provided on the top end of the Y-shaped tube 1. The sockets 7 are blind holes, and the sockets 7 and the latch 6 can be assembled and disassembled by plugging. The plurality of sockets 7 are designed to be annular, and the center of the circle of the plurality of sockets 7 in annular shape is concentric with the center of the circle of the connecting rod 405.

[0028] According to the operation method in Example 1, when the connecting rod 405 rotates, the circular plate 5 together with the pin 6 rotates around the axis of the connecting rod 405 until the tight fit between the sealing plate 407 and the mounting plate 2 reaches the range required by the staff. The staff then screws the pin 6 into the current corresponding socket 7, thereby locking the tight fit between the mounting plate 2 and the sealing plate 407, preventing the connecting rod 405 from being accidentally touched by external force, which would cause the tight fit between the sealing plate 407 and the mounting plate 2 to fail, thereby ensuring the sealing effect after the sealing plate 407 blocks the drainage hole 3.
