[0001] The utility model relates to the technical field of gate valves, in particular to a gate valve with impact resistance. Background Art

[0002] A gate valve is a commonly used fluid control device used to regulate the flow of fluid in a pipeline.

Its main advantages include simple structure, reliable sealing, low flow resistance, and high temperature resistance. It can meet the flow control needs of various media (such as water, oil, gas, etc.).

[0003] However, when the existing gate valve is in use, its valve plate is often easily impacted by high-pressure water flow, which can easily cause damage to the gate valve, and then easily cause the gate valve to leak, reducing the safety of the gate valve. Therefore, we propose an impact-resistant gate valve to solve the above problems. Utility Model Content

[0014] The peripheral side of the bottom surface of the anti-impact head is arranged in an arc shape. Beneficial effects

[0015] The utility model provides a gate valve with impact resistance. Compared with the prior art, it has the following beneficial effects:

[0016] The impact-resistant gate valve can provide space for the water inlet, water outlet and water guide hole through the valve body, and can also connect the water inlet and water outlet to external pipes respectively, thereby facilitating liquid circulation. At the same time, it can also install and fix the stabilizing component. Then, through the water guide hole, the water inlet and water outlet can be connected, and the plug-in installation of the blocking component can be carried out.

[0017] Since a rotating screw is inserted in the middle of the stabilizing component, and a blocking component is inserted in the inner cavity of the water guide hole, and the top of the blocking component is rotatably connected to the bottom end of the rotating screw, when liquid needs to circulate, the rotating screw is driven to rotate, thereby driving the blocking component to move upward, and then the bottom end of the blocking component can be made higher than the water outlet hole, so that the liquid enters from the water inlet hole and then flows out from the water outlet hole. Since the bottom end of the blocking component is rotatably connected to the anti-impact component, the impact component can make the circulating liquid directly impact its bottom end, causing the liquid to surge, thereby reducing the impact damage of the circulating liquid on the blocking component;

[0018] When it is necessary to intercept liquid, the rotating screw installed on the stabilizing component is rotated in the opposite direction to drive the sealing component to move downward, so that the bottom end of the sealing component is located below the water outlet. At this time, the liquid will not flow, and the bottom end of the sealing component and the impact-resistant component that are impacted will not affect the interception of the liquid, thereby improving the safety and service life of the gate valve.

[0028] Through the valve body 1, space can be provided for the water inlet 2, the water outlet 3 and the water guide hole 4, and the water inlet 2 and the water outlet 3 can be connected to the external pipes respectively, so as to facilitate the circulation of liquid. At the same time, the stabilizing component 5 can be installed and fixed. Then, through the water guide hole 4, the water inlet 2 and the water outlet 3 can be connected, and the plugging component 7 can be installed as a plug-in. Since a rotating screw 6 is inserted in the middle of the stabilizing component 5, and a plugging component 7 is inserted in the inner cavity of the water guide hole 4, and the top of the plugging component 7 is rotatably connected to the bottom end of the rotating screw 6, when it is necessary to circulate liquid, the rotating screw 6 is driven to rotate, thereby driving the plugging component 7 to move upward, so that the bottom end of the plugging component 7 can be higher than the water outlet The hole 3 is positioned so that the liquid enters from the water inlet hole 2 and then flows out from the water outlet hole 3. Since the bottom end of the sealing component 7 is rotatably connected to the anti-impact component 8, the circulating liquid can directly impact its bottom end through the impact component 8, causing the liquid to surge, reducing the impact damage of the circulating liquid on the sealing component 7. When it is necessary to intercept the liquid, the rotating screw 6 installed on the stabilizing component 5 is rotated in the opposite direction, thereby driving the sealing component 7 to move downward, and then the bottom end of the sealing component 7 can be located below the water outlet hole 3. At this time, the liquid will not circulate, and the bottom end of the sealing component 7 and the anti-impact component 8 that are impacted will not affect the retention of the liquid, thereby improving the safety and life of the gate valve.

Then, fixing screws 54 can be installed through the four mounting holes 53, so that the baffle 51 can be fixed to the top surface of the valve body 1, thereby improving the stability of the baffle 51 during use.

[0031] See Figure 2 、 Figure 4 and Figure 5 The sealing component 7 includes a sealing column 71 arranged in the inner cavity of the water guide hole 4, a first screw hole 72 is opened on the top surface of the sealing column 71, and the inner cavity of the first screw hole 72 is rotatably connected to the rotating screw 6, a second screw hole 73 is opened at the bottom end of the sealing column 71 for rotating the anti-impact component 8, and guide grooves 74 are opened on both sides of the top surface of the sealing column 71, and fixing grooves are opened on both sides of the top surface of the valve body 1 and the inner cavity of the water guide hole 4; a guide portion 75 is provided above the sealing column 71, and The two sides of the bottom of the guide portion 75 are plugged into the inner cavity of the guide groove 74, and the two sides of the top surface of the guide portion 75 are plugged into the inner cavities of the two fixed grooves.

The bottom ends of the two guide posts 752 are plugged into the inner cavities of the two guide grooves 74.

[0032] The sealing column 71 in the blocking assembly 7 can be inserted and installed in the inner cavity of the water guide hole 4, and can provide space for the first screw hole 72, the second screw hole 73, the two guide grooves 74 and the multiple groove rings 76, and can also block the water guide hole 4. Since the bracket 751 is engaged in the fixed groove, and the guide columns 752 are provided on both sides of the bottom surface of the bracket 751, and the bottom ends of the two guide columns 752 are connected to the inner cavities of the two guide grooves 74 by plugging, the sealing column 71 can be driven to rotate through the first screw hole 72 by rotating the screw 6. , and with the limit of the guide groove 74 of the guide column 752, the sealing column 71 can only move downward, and then the position of the sealing column 71 can be adjusted so that the sealing column 71 can block the water outlet 3. The anti-impact component 8 can be installed through the second screw hole 73, so that the anti-impact component 8 can be directly impacted by the liquid when the liquid circulates, thereby protecting the sealing column 71.

Since the bottom end of the sealing component 7 is rotatably connected to the anti-impact component 8, the circulating liquid can directly impact its bottom end through the impact component 8, causing the liquid to surge, reducing the impact damage of the circulating liquid on the sealing component 7.

Then, fixing screws 54 can be installed through the four mounting holes 53, so that the baffle 51 can be fixed to the top surface of the valve body 1, thereby improving the stability of the baffle 51 during use.

[0037] The sealing column 71 in the blocking assembly 7 can be inserted and installed in the inner cavity of the water guide hole 4, and can provide space for the first screw hole 72, the second screw hole 73, the two guide grooves 74 and the multiple groove rings 76, and can also block the water guide hole 4. Since the bracket 751 is engaged in the fixed groove, and the guide columns 752 are provided on both sides of the bottom surface of the bracket 751, and the bottom ends of the two guide columns 752 are connected to the inner cavities of the two guide grooves 74 by plugging, the sealing column 71 can be driven to rotate through the first screw hole 72 by rotating the screw 6. , and with the limit of the guide groove 74 of the guide column 752, the sealing column 71 can only move downward, and then the position of the sealing column 71 can be adjusted so that the sealing column 71 can block the water outlet 3.
