Description

Technical Field

[0001] The utility model relates to the field of stop valves, and more specifically, to a self-gathering titanium stop valve. Background Art

[0002] The self-gathering titanium stop valve is a device made of self-gathering titanium that controls whether the flowable medium is connected between the inlet pipe and the outlet pipe through the valve stem. When using the stop valve, the distance of the threaded rod inserted into the valve body is controlled by the rotating wheel, and then it is determined whether the sealing plug blocks the connection between the inlet pipe and the outlet pipe, which can effectively stop the valve. However, in actual use, the sealing plug will be worn out for a long time, which will affect the use of the stop valve to a certain extent. Generally, it is necessary to replace the sealing plug to extend the service life, but the entire replacement of the sealing plug will still cause a waste of resources to a certain extent. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a self-closing titanium stop valve which can prevent accidental opening.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-converging titanium stop valve, comprising a valve body, a water inlet pipe and a water outlet pipe are arranged on one side of the valve body, a threaded rod is threadedly inserted into the top of the valve body, a rotating wheel is fixedly connected to the top of the threaded rod, a sealing plug is fixedly connected to the bottom of the threaded rod, a connecting device is arranged on the surface of the sealing plug, a buffer device is arranged on one side of the water inlet pipe, the connecting device comprises a rubber tube, and the rubber tube is slidably sleeved on the surface of the sealing plug.

[0005] By adopting the above technical solution, when the connecting device is used, when the sealing plug is worn, the old rubber tube is directly removed and a new rubber tube is put on the surface of the sealing plug. This extends the service life of the sealing plug to a certain extent and reduces the waste of resources to a certain extent.

[0006] The utility model is further configured as follows: the surface of the sealing plug is evenly provided with retaining grooves, the inner wall of the retaining groove is provided with a first rubber ring, one side of the first rubber ring is fixedly connected to the inner wall of the rubber tube, the top of the first rubber ring is provided with a fixing hole, the bottom of the rubber tube is fixedly connected to a connecting plate, the bottom of the sealing plug is provided with a limiting groove, the inner wall of the limiting groove is slidably connected to a second rubber ring, and the bottom of the second rubber ring is fixedly connected to the top of the connecting plate.

[0007] By adopting the above technical solution, after the rubber tube is sleeved on the surface of the sealing plug, the first rubber ring is squeezed into the inside of the positioning groove, and the second rubber ring is squeezed into the inside of the limiting groove, so that the rubber tube and the surface of the sealing plug can be connected more tightly.

[0008] The utility model is further configured as follows: the inner wall of the fixing hole is slidably connected with a fixing rod, the fixing rod is slidably inserted into the top of the sealing plug, the top of the fixing rod is connected with a supporting ring, the inner wall of the supporting ring is rotatably provided with a threaded barrel, and the threaded barrel is threadedly sleeved on the surface of the threaded rod.

[0009] By adopting the above technical solution, the threaded tube is manually controlled to rotate on the surface of the threaded rod, so that the fixing rod is inserted into the top of the sealing plug, and then the fixing rod passes through the fixing hole, so that the new rubber tube can be fixed on the surface of the sealing plug.

[0010] The utility model is further configured as follows: the buffer device includes a rectangular frame, the rectangular frame is fixedly connected to one side of the water inlet pipe, the inner wall of the rectangular frame is fixedly connected to a support rod, one side of the support rod is fixedly connected to a first spring, one end of the first spring away from the support rod is fixedly connected to a rubber block, a first damping rod is arranged inside the first spring, one end of the first damping rod is fixedly connected to one end of the support rod, one end of the first damping rod away from the support rod is fixedly connected to one side of the rubber block, and the rubber block is slidably connected to the inner wall of the rectangular frame.

[0011] By adopting the above technical solution, when the valve is closed, the water flow from the water inlet pipe will hit the valve. At this time, the water flow will squeeze the rubber block, causing the first spring to be stretched, thereby causing the rubber block to slide out of the rectangular frame, so that water can flow out of the valve body from the rectangular frame, thereby reducing the impact force of the water flow on the valve to a certain extent.

[0012] The utility model is further configured as follows: a sliding groove is provided on the inner wall of the rectangular frame, an L-shaped plate is slidably connected to the inner wall of the sliding groove, a rubber plate is fixedly connected to one side of the L-shaped plate, a second damping rod is fixedly connected to the top of the L-shaped plate, the top of the second damping rod is fixedly connected to the bottom of the rectangular frame, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to the bottom of the L-shaped plate, one end of the second spring close to the second damping rod is fixedly connected to the bottom of the rectangular frame, a round rod is slidably connected to the inner wall of the sliding groove, and the round rod is fixedly connected to the bottom of the sealing plug.

[0013] By adopting the above technical solution, when the sealing plug is completely squeezed to the top of the water inlet pipe, the round rod completely squeezes the L-shaped plate out of the rectangular frame, thereby allowing the water flow to enter the rectangular frame. Because the sealing plug is still a certain distance away from blocking the water inlet pipe after blocking the water outlet pipe, after buffering the water flow, the threaded rod is rotated in the opposite direction so that the round rod no longer squeezes the top of the L-shaped plate, thereby allowing the L-shaped plate to block the rectangular frame.
