Description

Technical Field

[0001] The utility model belongs to the field of ball valves, and more specifically relates to a bidirectional hard-sealed ball valve. Background Art

[0002] At present, the traditional floating ball valve is constructed as follows: it includes a valve body, a valve cover, a ball, a valve stem and a handle. The valve body is connected to the valve cover, the bottom of the valve stem is connected to the ball, a valve seat is arranged in the valve body, and the ball is placed between the valve seats. During the use of the ball valve, it will be contaminated by oil or fat, which will affect the normal operation and sealing performance of the ball valve. In addition, if the valve body is not cleaned for a long time or is only cleaned with water, it is easy to cause bacteria to grow, equipment aging, and reduce the service life. Therefore, it is necessary to design a two-way hard-sealed ball valve that can effectively sterilize the pipe when cleaning the ball valve, ensure clean use, and reduce the ball valve contamination by oil and fat, which causes the sealing performance to be reduced. Utility Model Content

[0003] The utility model arranges an ultraviolet lamp in the valve body, so that when the ball valve needs to be cleaned, it can be cleaned with acetone liquid first and then illuminated with ultraviolet lamp. By setting a timer, the ultraviolet lamp stops irradiating when the irradiation time is reached while executing the irradiation timing task, which can reduce the waiting time of manual operation. By setting a liquid level sensor, when the valve ball is closed and the liquid level sensor detects that the water flow is reduced, the controller will control the ultraviolet lamp to irradiate, and the irradiation time is set manually, so that the opening and closing of the ultraviolet lamp does not require the staff to wait nearby, thereby reducing manpower. Since dust and oil on the ultraviolet lamp tube will affect the penetration ability of ultraviolet rays, by arranging the ultraviolet lamp in the channel of the valve body, the acetone liquid just cleans the ultraviolet lamp tube when the valve body is cleaned, thereby ensuring the use efficiency and service life of the ultraviolet lamp. The ultraviolet lamp can effectively sterilize the tube when the ball valve is cleaned, ensuring clean use. By adopting a fluorosilicone rubber valve ball, the ball valve can be reduced from being contaminated by engine oil and fat, which causes the sealing performance to be reduced.

[0004] The bidirectional hard-sealed ball valve comprises a valve body, a valve cover, a valve ball, a valve stem and a controller.

[0005] The valve body is connected to the valve cover, the valve ball is matched and arranged in the valve body, the bottom of the valve stem is connected to the valve ball, the upper end of the valve stem is connected to a handle, a liquid level sensor is arranged at the bottom of the channel in the valve body, an ultraviolet lamp is arranged on the channel in the valve body, the output end of the liquid level sensor is connected to the input end of the controller, and the output end of the controller is connected to the ultraviolet lamp.

[0006] Furthermore, the valve ball is a fluorosilicone rubber valve ball.

[0007] Furthermore, sealing rings are provided between the valve body and the valve stem, and between the valve body and the valve cover.

[0008] Furthermore, a timer is provided in the controller.

[0009] Beneficial effects of the utility model:

[0010] (1) By setting a timer, the UV lamp will stop irradiating when the irradiation time is reached while executing the irradiation time task, which can reduce the waiting time for manual operation. By setting a liquid level sensor, when the valve ball is closed and the liquid level sensor detects a decrease in water flow, the controller will control the UV lamp to irradiate, and the irradiation time is set manually, so that the UV lamp can be turned on and off without the need for staff to wait nearby, reducing manpower.

[0011] (2) During use, the ball valve may be contaminated by engine oil or fat, thereby affecting the normal operation and sealing performance of the ball valve. The utility model adopts a fluorosilicone rubber valve ball, which can reduce the contamination of the ball valve by engine oil and fat and the reduction of sealing performance.

[0012] (3) If the valve body is not cleaned for a long time or is only cleaned with clean water, it is easy to cause bacterial growth, equipment aging, and shorten the service life. In the present application, by arranging an ultraviolet lamp in the valve body, it can be cleaned with acetone liquid first and then with ultraviolet light. If the ultraviolet light penetration ability is affected by dust and oil on the ultraviolet lamp tube, by arranging the ultraviolet lamp in the channel of the valve body, the acetone liquid can clean the ultraviolet lamp tube when the valve body is cleaned, thereby ensuring the use efficiency and service life of the ultraviolet lamp.

[0016] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0018] The utility model arranges an ultraviolet lamp in the valve body, so that when the ball valve needs to be cleaned, it can be cleaned with acetone liquid first and then illuminated with ultraviolet lamp. By setting a timer, the ultraviolet lamp stops irradiating when the irradiation time is reached while executing the irradiation timing task, which can reduce the waiting time of manual operation. By setting a liquid level sensor, when the valve ball is closed and the liquid level sensor detects that the water flow is reduced, the controller will control the ultraviolet lamp to irradiate, and the irradiation time is set manually, so that the opening and closing of the ultraviolet lamp does not require the staff to wait nearby, thereby reducing manpower. Since dust and oil on the ultraviolet lamp tube will affect the penetration ability of ultraviolet rays, by arranging the ultraviolet lamp in the channel of the valve body, the acetone liquid just cleans the ultraviolet lamp tube when the valve body is cleaned, thereby ensuring the use efficiency and service life of the ultraviolet lamp. The ultraviolet lamp can effectively sterilize the tube when the ball valve is cleaned, ensuring clean use. By adopting a fluorosilicone rubber valve ball, the ball valve can be reduced from being contaminated by engine oil and fat, which causes the sealing performance to be reduced.

[0019] Example 1: Figure 1-2 As shown, the bidirectional hard-sealed ball valve includes a valve body 1 , a valve cover 2 , a valve ball 3 , a valve stem 4 , and a controller 8 .

[0020] The valve body 1 is connected to the valve cover 2, and the valve ball 3 is matched and arranged in the valve body 1. The valve ball 3 is a fluorosilicone rubber valve ball. The fluorosilicone rubber valve ball has heat resistance and cold resistance, and can be used for a long time below 200°C and for a short time above 250°C. At the same time, fluorosilicone rubber has the excellent hydrogen solvent resistance, oil resistance, acid and alkali resistance and lower surface energy performance of organic fluorine materials, and has excellent stability to organic solvents, inorganic acids and oxidants, especially excellent acid resistance. By adopting a fluorosilicone rubber valve ball, the ball valve can be less polluted by engine oil and fat, which causes the sealing performance to be reduced. The bottom of the valve stem 4 is connected to the valve ball 3, and the upper end of the valve stem 4 is connected to the handle 5. When in use, by turning the handle 5, the valve stem 4 drives the valve ball 3 to rotate. When the through holes on both sides of the valve ball 3 rotate to connect with the channel of the valve body 1, it is in the open state; when the through holes on both sides of the valve ball 3 rotate to be opposite to the channel of the valve body 1, it is in the closed state.

[0021] A liquid level sensor 6 is provided at the bottom of the inner channel of the valve body 1, and an ultraviolet lamp 7 is provided on the inner channel of the valve body 1. The output end of the liquid level sensor 6 is connected to the input end of the controller 8, and the output end of the controller 8 is connected to the ultraviolet lamp 7. A timer 9 is provided in the controller 8. When cleaning the ball valve, turn on the switch of the controller 8.

[0022] When the ball valve needs to be cleaned, acetone liquid is first poured in. The acetone liquid cleans the lamp tube of the ultraviolet lamp 7, ensuring the use efficiency and service life of the ultraviolet lamp 7. At the same time, the poured acetone liquid can also effectively sterilize the tube when the ball valve is cleaned, ensuring clean use. Since the ball valve will be contaminated by engine oil or fat during use, the normal operation and sealing performance of the ball valve will be affected. In the utility model, after cleaning with acetone liquid, the valve ball 3 is closed. When the liquid level sensor 6 detects that the liquid level is lower than the sensor, the controller 8 controls the ultraviolet lamp 7 to irradiate and sterilize the tube, which can effectively sterilize the tube when the ball valve is cleaned, ensuring clean use. By setting a timer 9, the ultraviolet lamp 7 stops irradiating when the irradiation time is reached when performing the irradiation timing task, which can reduce the waiting time of manual operation. By setting a liquid level sensor 6, when the valve ball 3 is closed, the liquid level sensor 6 detects that the water flow is reduced, the controller 8 will control the ultraviolet lamp 7 to irradiate, and the irradiation time is set manually, so that the opening and closing of the ultraviolet lamp 7 does not require the staff to wait by the side, reducing manpower.

[0023] Sealing rings are provided between the valve body 1 and the valve stem 4, and between the valve body 1 and the valve cover 2, to ensure the normal operation and sealing performance of the ball valve during use.

[0024] Working principle of this utility model:

[0025] When in use, by turning the handle 5, the valve stem 4 drives the valve ball 3 to rotate. When the through holes on both sides of the valve ball 3 rotate to connect with the valve body 1 channel, it is in the open state; when the through holes on both sides of the valve ball 3 rotate to be opposite to the valve body 1 channel, it is in the closed state. When cleaning the ball valve, turn on the controller 8 switch. First, pour in acetone liquid, which is just right for cleaning the ultraviolet lamp 7 lamp tube. After cleaning with acetone liquid, close the valve ball 3. When the liquid level sensor 6 detects that the liquid level is lower than the sensor, the controller 8 controls the ultraviolet lamp 7 to irradiate and sterilize the tube. The timer 9 performs the irradiation timing task and stops irradiation when the time is up.

[0026] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
