Description

Technical Field

[0001] This utility model relates to the field of stainless steel valve technology, and in particular to a drip-proof stainless steel valve. Background Technology

[0002] Stainless steel valves are typically used in applications requiring strong corrosion resistance, such as in the chemical, petroleum, and natural gas industries. They are characterized by corrosion resistance, high temperature resistance, and wear resistance, making them suitable for controlling and regulating various media.

[0003] Existing technologies often have the following drawbacks: In the actual use of stainless steel valves, when the stainless steel valve is connected to the pipeline, the sealing gasket between the stainless steel valve and the flange on the pipeline ages, and leakage often occurs at the connection between the pipeline and the stainless steel valve flange, thereby reducing the sealing effect of the stainless steel valve during use.

[0004] Therefore, this utility model provides a drip-proof stainless steel valve. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where aging of the sealing gasket between the stainless steel valve and the flange on the pipeline can easily lead to leakage at the connection between the pipeline and the stainless steel valve flange. Therefore, this invention proposes a leak-proof stainless steel valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drip-proof stainless steel valve, comprising a valve body and a pipe, wherein a handle is installed on the upper side of the valve body, and a first flange is fixedly installed at both ends of the valve body, and a second flange is fixedly connected to the end face of the pipe, wherein the surface of the first flange is provided with a drip-proof structure, the drip-proof structure comprising two barbs respectively fixedly installed on the first flange and the second flange, and the surface of the two barbs is covered with silicone tape.

[0007] The effect achieved by the above components is that by first putting the silicone strip on the surface of the barbed hook, the initial installation of the silicone strip can be achieved.

[0008] Preferably, a connecting plate is fixedly connected to the side wall of the valve body, a fixed rod is slidably connected inside the connecting plate, a driving plate is fixedly connected to the end face of the fixed rod, and a plurality of spikes are uniformly fixedly connected to the surface of the driving plate.

[0009] The effect achieved by the above components is as follows: after the silicone tape is wrapped around the side walls of the first flange and the second flange, the other end of the silicone tape is placed on the surface of the barb, which can achieve the initial installation of both ends of the silicone tape.

[0010] Preferably, the connecting plate is internally threaded with a screw, and the screw is internally rotatably connected to the drive plate.

[0011] The effect achieved by the above components is as follows: the screw drives the drive plate to move, the starting fixing rod slides inside the connecting plate to limit the direction of movement of the drive plate, and the drive plate drives the silicone strip to tighten the side walls of the first flange and the second flange, thereby achieving tight coverage of the connection gap between the first flange and the second flange.

[0012] Preferably, a rotating block is fixedly connected to the end of the screw away from the connecting plate.

[0013] The effect achieved by the above components is that the rotating block facilitates the twisting of the screw.

[0014] Preferably, the side wall of the handle is provided with an adjustment structure, the adjustment structure including a limiting ring rotatably connected to the side wall of the handle, a circular rod fixedly connected to the side wall of the limiting ring, and a stop rod fixedly connected to the side wall of the valve body.

[0015] The effect achieved by the above components is that by rotating the limiting ring on the side wall of the handle, the movement path between the circular rod and the stop bar on the handle can be adjusted.

[0016] Preferably, a positioning plate is fixedly connected to the upper side of the limiting ring, and bolts are threaded into the internal part of the positioning plate.

[0017] The effect achieved by the above components is that rotating the bolts inside the positioning plate can fix the drive rear limit ring and the handle.

[0018] Preferably, the side wall of the handle is provided with a plurality of insertion holes evenly distributed, and the size of the insertion holes is adapted to the size of the bolts.

[0019] The effect achieved by the above components is that inserting the bolt into the inner wall of the corresponding hole on the handle improves the stability of fixing the rotation limit ring and the handle.

[0020] In summary:

[0021] 1. In this utility model, the drive plate will drive the silicone strip to tighten the side walls of the first flange and the second flange, thereby achieving tight coverage of the connection gap between the first flange and the second flange. This avoids the situation where the sealing gasket at the connection point of the stainless steel valve and the pipeline is prone to leakage due to aging. By setting the anti-drip structure, further sealing can be achieved between the valve body and the pipeline connection, further improving the anti-drip effect of the valve body during use and further improving the performance of the stainless steel valve.

[0022] 2. In this utility model, by setting an adjustment structure, it is convenient to adjust the size of the handle twisting path on the valve body, and to quickly adjust the flow rate of a specific liquid, thereby further improving the performance of the stainless steel valve.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a drip-proof stainless steel valve, including a valve body 1 and a pipe 3. A handle 2 is installed on the upper side of the valve body 1. A first flange 4 is fixedly installed at both ends of the valve body 1. A second flange 5 is fixedly connected to the end face of the pipe 3. A drip-proof structure 6 is provided on the surface of the first flange 4. An adjustment structure 7 is provided on the side wall of the handle 2.

[0030] The following section will explain the specific design and function of its anti-drip structure 6 and adjustment structure 7.

[0031] Reference Figures 1-3As shown in this embodiment: the anti-drip structure 6 includes two barbs 62 respectively fixedly installed on the first flange 4 and the second flange 5, and silicone tape 61 is sleeved on the surface of the two barbs 62. The silicone tape 61 is first sleeved on the surface of the barbs 62 to achieve preliminary installation of the silicone tape 61. A connecting plate 63 is fixedly connected to the side wall of the valve body 1, and a fixing rod 64 is slidably connected inside the connecting plate 63. A driving plate 66 is fixedly connected to the end face of the fixing rod 64, and several barbs 67 are evenly fixedly connected to the surface of the driving plate 66. After the silicone tape 61 is wrapped around the side wall of the first flange 4 and the second flange 5, the other end of the silicone tape 61 is sleeved on the surface of the barb 67, thus achieving preliminary installation of both ends of the silicone tape 61.

[0032] A screw 65 is internally threaded onto the connecting plate 63, and the screw 65 is rotatably connected to the drive plate 66. The screw 65 drives the drive plate 66 to move. The starting fixing rod 64 slides inside the connecting plate 63, which restricts the movement direction of the drive plate 66. The drive plate 66 drives the silicone tape 61 to tighten the side walls of the first flange 4 and the second flange 5, thereby achieving a tight cover of the connection gap between the first flange 4 and the second flange 5. A rotating block 68 is fixedly connected to the end of the screw 65 away from the connecting plate 63. Rotating the rotating block 68 facilitates the torsion of the screw 65.

[0033] Reference Figures 1-2 and Figures 4-5 As shown, specifically, the side wall of the handle 2 is provided with an adjustment structure 7. The adjustment structure 7 includes a limiting ring 71 rotatably connected to the side wall of the handle 2, a circular rod 73 fixedly connected to the side wall of the limiting ring 71, and a stop rod 72 fixedly connected to the side wall of the valve body 1. By rotating the limiting ring 71 on the side wall of the handle 2, the movement path between the circular rod 73 and the stop rod 72 on the handle 2 can be adjusted.

[0034] A positioning plate 74 is fixedly connected to the upper side of the limiting ring 71, and a bolt 75 is threaded into the interior of the positioning plate 74. Rotating the bolt 75 inside the positioning plate 74 secures the limiting ring 71 and the handle 2. Several insertion holes 76 are evenly distributed on the side wall of the handle 2, and the size of the insertion holes 76 matches the size of the bolts 75. Inserting the bolts 75 into the inner wall of the corresponding insertion holes 76 on the handle 2 improves the stability of securing the rotating limiting ring 71 and the handle 2.

[0035] Working principle: First, the silicone tape 61 is placed on the surface of the barbed hook 62, which achieves the initial installation of the silicone tape 61. After the silicone tape 61 is wrapped around the side walls of the first flange 4 and the second flange 5, the other end of the silicone tape 61 is placed on the surface of the barbed shank 67, which achieves the initial installation of both ends of the silicone tape 61. Then, the rotating block 68 is rotated. The rotating block 68 is designed to facilitate the twisting of the screw 65. The screw 65 will drive the drive plate 66 to move. The starting fixing rod 64 slides inside the connecting plate 63, which restricts the movement of the drive plate 66. The drive plate 66, under the action of the direction, will cause the silicone strip 61 to tighten the side walls of the first flange 4 and the second flange 5, thereby achieving a tight cover of the connection gap between the first flange 4 and the second flange 5. This avoids the situation where the sealing gasket at the connection point of the stainless steel valve and the pipe 3 is prone to leakage due to aging. By setting the anti-drip structure 6, further sealing can be achieved between the valve body 1 and the pipe 3, further improving the anti-drip effect of the valve body 1 during use and further improving the performance of the stainless steel valve.

[0036] When personnel need to control the opening size of valve body 1, rotating the limiting ring 71 on the side wall of handle 2 adjusts the movement path between the circular rod 73 and the stop rod 72 on handle 2. After moving the circular rod 73 to the appropriate position, rotating the bolt 75 inside the positioning plate 74 and inserting the bolt 75 into the inner wall of the corresponding insertion hole 76 on handle 2 fixes the limiting ring 71 and handle 2. The operator can control the opening size of the valve according to the movement path between the stop rod 72 and the circular rod 73, which facilitates the use of valve body 1 in some special situations and avoids the situation where the liquid flow speed in pipeline 3 is too fast due to the valve body 1 being opened too large, resulting in liquid waste. By setting the adjustment structure 7, it is convenient to adjust the size of the twisting path of handle 2 on valve body 1, which facilitates the rapid adjustment of a specific liquid flow rate and further improves the performance of stainless steel valves.
