Description

Technical Field

[0001] The present invention relates to the field of valves, and in particular to a high-strength ball valve. Background Art

[0002] A ball valve is a valve that controls the on-off of fluid by rotating a sphere. The closing and opening member is a sphere with a circular through-hole. The sphere is driven by a valve stem and rotates around the axis of the ball valve. When using a high-strength ball valve to control the flow of high-temperature liquid, since the temperature rise of the high-temperature liquid will cause changes in the material properties of the ball valve, it is easy to occur the phenomenon of damage and leakage of the ball valve. Therefore, it is necessary to cool down the ball valve to ensure that the ball valve can work normally. One of the conventional cooling devices is continuous cooling treatment. This method has a good cooling effect but wastes water resources. Another is to manually control the cooling during the temperature rise, which wastes manpower. Therefore, a high-strength ball valve with an automatic cooling function is proposed to solve the above problems. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a high-strength ball valve. The ball valve of the present invention has an automatic cooling function and can realize the opening and closing of the cooling function with the change of temperature.

[0020] The present invention will be described in detail in combination with the drawings in the embodiments of the present invention.

[0021] Refer to Figure 3-5 and Figure 8 ,

[0022] A high-strength ball valve includes a valve body 101. Two connecting pipes 102 are integrally cast on the valve body 101. A valve core 103 is rotatably connected in the valve body 101 through a bearing. The upper end of the valve core 103 is connected with a triggering mechanism. A cold water pipe 401 is fixedly connected to the upper end of the valve body 101 through bolts. A nozzle 403 is fixedly connected to the lower end of the cold water pipe 401. A connecting pipe 301 is welded to one end of the cold water pipe 401. A plunger 302 is slidably connected in the connecting pipe 301. A water inlet pipe 303 is welded to the connecting pipe 301.

[0023] When using the ball valve, first, high-temperature liquid is introduced into the valve body 101 through the connecting pipe 102, and the high-temperature liquid passes through the valve core 103 and then is discharged through another connecting pipe 102.

[0024] When the liquid temperature inside the valve body 101 rises, the temperature causes the triggering mechanism to trigger, driving the plunger 302 to slide upward. After the plunger 302 slides upward, the water inlet pipe 303 is connected to the cold water pipe 401. The water inlet pipe 303 is used to connect to high-pressure cold water. The cold water enters the connecting pipe 301 through the water inlet pipe 303, then enters the cold water pipe 401 through the connecting pipe 301, and finally sprays out through the nozzle 403. The sprayed cold water cools the surface of the valve body 101.

[0025] See Figure 6 ,

[0026] The triggering mechanism includes a fixed pipe 201. The fixed pipe 201 is fixedly connected to the surface of the valve body 101. A sliding rod 204 is slidably connected inside the fixed pipe 201. A sliding plug 202 is fixedly connected to the lower end of the sliding rod 204. The sliding plug 202 is slidably connected inside the fixed pipe 201. The sliding rod 204 extends into the connecting pipe 301 and is fixedly connected to the plunger 302.

[0027] Embodiment 1 of pushing the sliding plug 302 upward by the thermal expansion of kerosene:

[0028] Kerosene is contained in the fixed pipe 201. The kerosene can expand when heated. After the surface of the valve body 101 is heated, the kerosene in the fixed pipe 201 expands due to heat, thereby pushing the sliding plug 202 upward. The sliding plug 202 pushes the sliding rod 204 upward, and the sliding rod 204 drives the plunger 302 upward to realize the function of spraying cold water. Through the above structure, the change in liquid temperature can be used to control the structure to cool the valve, which neither wastes water resources through continuous cooling treatment nor wastes manpower through manual control.

[0029] Embodiment 2 of pushing the sliding plug 302 upward by the thermal expansion of kerosene:

[0030] The bottom diameter of the fixed pipe 201 is large, and the top diameter of the fixed pipe 201 is small. The sliding plug 202 slides within the top region of the fixed pipe 201, so that more kerosene can be accommodated at the bottom. When thermal expansion and contraction occur, the stroke change of the sliding plug 202 is more obvious, further accelerating the discharge of cold water.

[0031] See Figure 3 ,

[0032] A first spring 203 is sleeved on the sliding rod 204. The first spring 203 is located between the sliding plug 202 and the top wall of the fixed pipe 201.

[0033] When the surface temperature of the valve body 101 decreases, the temperature is transferred to the kerosene in the fixed pipe 201, and the temperature of the kerosene decreases accordingly, causing the volume of the kerosene to contract. At this time, the sliding plug 202 automatically resets under the elastic action of the first spring 203, and at the same time drives the plunger 302 to reset downward. The plunger 302 blocks the communication pipe 301, thereby preventing cold water from spraying out and achieving the purpose of saving resources.

[0034] See Figure 7 ,

[0035] The upper end of the valve core 103 is fixedly connected to the valve switch 105. The staff can manually operate the valve switch 105, and then can control the rotation of the valve core 103 to realize the opening and closing function of the valve. When the through channel on the valve core 103 is communicated with the two connecting pipes 102, the valve is in the open state. When the valve core 103 rotates another ninety degrees, the valve is in the closed state.

[0036] See Figure 6-7 ,

[0037] A lock sleeve 205 is welded on the sliding rod 204, and two limit blocks 106 are welded and fixedly connected to the lower end of the valve switch 105. The lock sleeve 205 can be sleeved on the two limit blocks 106.

[0038] When the sliding rod 204 moves upward to turn on the cooling function, the sliding rod 204 drives the lock sleeve 205 to move upward. Then the lock sleeve 205 can be sleeved on the two limit blocks 106 to realize the limit of the valve switch 105. At this time, unauthorized personnel cannot close the valve by turning the valve switch 105, thus avoiding the situation that unauthorized personnel close the valve when it is exposed to high temperature, resulting in an instant increase in the pressure inside the valve, and further avoiding damage and leakage of the valve due to the increased pressure at high temperature, and further ensuring the safety of the valve.

[0039] When the cooling temperature of the valve decreases, the sliding rod 204 automatically resets. When the lock sleeve 205 disengages from the two limit blocks 106, the staff can operate the valve switch 105. If it is necessary to urgently close the valve in case of an emergency, the staff can manually move the lock sleeve 205 to disengage it from the two limit blocks 106, and then operate the valve switch 105 to close the valve.

[0040] See Figure 3-4 ,

[0041] A second spring 405 is welded on the cold water pipe 401, and a bell 406 is welded on the second spring 405. A hammer 404 is rotatably connected to the outer wall of the cold water pipe 401 through a bearing. The hammer 404 is composed of three cylinders and three spheres.

[0042] See Figure 2 and Figure 4 ,

[0043] An impeller 402 is disposed in the cold water pipe 401 , and a rotating shaft of the impeller 402 is fixedly connected to a hammer 404 .

[0044] When cold water enters the cold water pipe 401 and is then sprayed out through the nozzle 403 , the water flow in the cold water pipe 401 can drive the impeller 402 to rotate, and the impeller 402 drives the hammer 404 to rotate.

[0045] The lower end of the cold water pipe 401 is fixedly connected to a hollow rod 501 by bolts, and a telescopic rod 502 is slidably connected inside the hollow rod 501. A plurality of water absorption holes are opened on the hollow rod 501, and water-absorbing resin is installed inside the hollow rod 501. When the temperature continues to rise for a period of time and is difficult to cool down, the water-absorbing resin gradually absorbs the water sprayed from the outside through the plurality of water absorption holes and expands, thereby pushing the telescopic rod 502 to extend, and the telescopic rod 502 pushes the bell 406 to move upward, so that the bell 406 comes into contact with the rotating hammer 404.

[0046] When the hammer 404 rotates, the three balls are used to sequentially move the bell 406, causing the bell 406 to make a sound. There is no need to control the bell 406 separately, thereby reminding the staff that the liquid temperature is too high, causing the valve to heat up, which makes it easier for the staff to take measures at the source of the increased liquid temperature, thereby further reducing safety risks.

[0047] When the water-absorbing resin starts to absorb water, it expands, causing the telescopic rod 502 to gradually extend. When the nozzle 403 stops spraying water, the water-absorbing resin stops absorbing water, and the water in the water-absorbing resin will naturally evaporate through multiple water absorption holes. At the same time, the surrounding temperature can also promote the evaporation of water in the water-absorbing resin. After the water in the water-absorbing resin evaporates, the water-absorbing resin naturally shrinks, allowing the telescopic rod 502 to automatically return to its initial state under the action of its own weight, thereby avoiding further extension and collision with the bell 406.

[0048] See also Figure 4 ,

[0049] The bell 406 is made of metal. When the metal bell 406 is turned, it can make a crisp sound, which is easy to remind the staff.

[0050] See also Figure 5-6 ,

[0051] The plunger 302 and the sliding plug 202 are both made of sealing rubber, which has good sealing properties and can prevent kerosene and cold water from leaking.

[0052] See also Figure 4 ,

[0053] The spray head 403 is a scattering spray head. Spray holes are provided around and at the bottom of the spray head 403. The spray holes around the spray head 403 can increase the coverage area of the cold water and facilitate the water absorption resin to absorb water at the same time. The scattering spray head can evenly cover the cold water on the surface of the valve body 101, so that the valve body 101 can obtain a comprehensive cooling effect.
