Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a regulating valve with a protective mechanism. Background Technology

[0002] Control valves, also known as regulating valves, are key equipment in industrial automation process control. They are mainly used to regulate process parameters such as flow rate, pressure, temperature, and liquid level of the medium. By receiving signals from the control system, they automatically adjust the valve opening to achieve precise control of process parameters.

[0003] Patent CN221424031U discloses an electric regulating valve with protective function, including an electric regulating valve body. A water inlet pipe is fixedly connected to the front end of the electric regulating valve body. A cleaning mechanism is provided inside the water inlet pipe, and a protective mechanism is provided on the upper side of the electric regulating valve body. The cleaning mechanism includes a filter screen fixedly installed inside the water inlet pipe. A fixing frame is fixedly installed inside the water inlet pipe near the rear end of the filter screen. A fixing rod is fixedly installed inside the fixing frame near the center, and a movable rod is movably sleeved on the outer side of the fixing rod. This electric regulating valve with protective function utilizes the impact of water flow on the water wheel to rotate, thereby driving the cleaning plate and brush to rotate. The brush cleans the filter screen fixed inside the water inlet pipe, preventing the accumulation of scale and impurities inside the electric regulating valve body, and simultaneously cleaning the filter screen in a timely manner.

[0004] The above-mentioned device has certain shortcomings in its use: the protective mechanism in the device is directly fixed to the electric regulating valve body. When the motor on the electric regulating valve body is under regular maintenance, the cover can only be opened. However, the overall exposed space is limited, which makes the maintenance operation more restrictive and inconvenient to use. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1:

[0041] Please see Figures 1-7 A regulating valve with a protective mechanism includes a conveying pipe 1, a valve body 3 installed on the outside of the conveying pipe 1, limit components 4 installed on both the left and right sides of the outer wall of the conveying pipe 1, a protective component 6 installed on the outside of the valve body 3, the protective component 6 being fixedly connected to the limit components 4, and an abutment component 5 installed on the inner wall of the limit components 4.

[0042] The protective component 6 includes a protective cover 61. The outer wall of the protective cover 61 is fixedly connected to the limiting component 4. The protective cover 61 is installed on the outside of the valve body 3. The inner wall of the protective cover 61 is equipped with sound insulation cotton 64. The bottom wall of the protective cover 61 is equipped with a support pad 63. The rear wall of the protective cover 61 has a heat dissipation vent 65. The bottom wall of the support pad 63 matches the specifications of the outer wall of the valve body 3. The bottom wall of the support pad 63 abuts against the outer wall of the valve body 3. The top wall of the protective cover 61 is equipped with a transparent observation window 62.

[0043] The limiting component 4 includes two fixing frames 46, which are arranged symmetrically from left to right. The two fixing frames 46 are fixedly installed on the outer wall of the conveying pipe 1 and located on both sides of the valve body 3. The top wall of the two fixing frames 46 is provided with a through groove 45, and the side wall of the two fixing frames 46 is provided with a slot 48 corresponding to the through groove 45. The outer wall of the protective cover 61 is fixedly installed with a connecting seat 41. The bottom wall of the two connecting seats 41 is fixedly installed with an elastic element 43. The bottom wall of the two elastic elements 43 is fixedly installed with a slot 44. The outer wall of the two elastic elements 43 is in contact with the inner wall of the corresponding through groove 45. The two slots 44 are engaged and fixed with the inner wall of the corresponding slot 48. The front and rear parts of the bottom wall of the two connecting seats 41 are fixedly installed with positioning rods 42. The top wall of the fixing frame 46 is provided with a positioning groove 47 corresponding to the positioning rod 42. The inner wall of several positioning grooves 47 is in contact with the outer wall of the corresponding positioning rod 42.

[0044] In this embodiment of the utility model, the purpose of this arrangement is that the protective cover 61 is mainly to provide comprehensive protection for the exterior of the valve body 3, so as to avoid damage caused by external forces. At the same time, the bottom wall of the support pad 63 abuts against the outer wall of the valve body 3, so that the bottom of the protective cover 61 fits more tightly with the exterior of the valve body 3. The heat dissipation vent 65 can dissipate the heat generated by the motor on the valve body 3 during operation, and the sound insulation cotton 64 can reduce the operating noise.

[0045] The setting of the limiting component 4 is used to abut and fix the protective cover 61 during installation, which improves the overall stability during installation. When it needs to be inspected regularly, it can also be quickly removed, increasing the maintenance operation space. With the cooperation of the positioning rod 42 and the positioning groove 47, it prevents the elastic element 43 from shifting position when it enters the through groove 45.

[0046] Example 2:

[0047] Please see Figures 1-7This embodiment provides a technical solution based on embodiment one: the abutting component 5 includes two abutting seats 55, the outer walls of the two abutting seats 55 are in contact with the inner walls of the corresponding through grooves 45, the outer walls of the two abutting seats 55 are abutted and fixed to the outer walls of the corresponding elastic members 43, the top walls of the two abutting seats 55 are rotatably mounted with adjusting rods 52, the bottom of the outer walls of the two adjusting rods 52 are provided with threads 53, the front and rear parts of the top walls of the two abutting seats 55 are fixedly mounted with abutting springs 54, the tops of several abutting springs 54 are fixedly connected to the bottom walls of the corresponding connecting seats 41, the top walls of the two connecting seats 41 are provided with threaded grooves 56, the inner walls of the two threaded grooves 56 are slidably connected to the outer walls of the corresponding adjusting rods 52, the tops of the two adjusting rods 52 are fixedly mounted with operating handles 51, and the left and right ends of the conveying pipe 1 are fixedly mounted with connecting flanges 2;

[0048] In this embodiment of the utility model, the purpose of this arrangement is that, after the limiting component 4 has installed the protective cover 61, the elastic element 43 will be driven by the external force to disengage the card seat 44 from the position of the card slot 48. The abutting seat 55 abuts and fixes the elastic element 43, which can improve the anti-dropping performance of the limiting component 4 after installation and further increase the installation stability of the protective cover 61.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0050] During operation, when the protective component 6 is installed on top of the valve body 3 for protection, the upward movement of the operating handle 51 causes the adjusting rod 52 to slide within the threaded groove 56. Rotating the operating handle 51 causes the adjusting rod 52 to move, so that the threaded wire 53 is screwed into the inner wall of the threaded groove 56. The abutment seat 55 compresses the abutment spring 54. The movable protective cover 61 causes the support pad 63 and sound insulation cotton 64 to be fitted onto the top of the valve body 3, thereby causing the limiting component 4 and the abutment component 5 to move synchronously. The bottom wall of the support pad 63 abuts and is fixed to the bottom outer wall of the valve body 3. When the protective cover 61 moves the connecting seat 41, it simultaneously causes the elastic element 43 and the retaining seat 44 to enter the inner wall of the passage groove 45, and the connection... The seat 41 drives the positioning rod 42 into the inner wall of the positioning groove 47. When the elastic element 43 and the card holder 44 enter the interior of the through groove 45, they are deformed by force, causing the card holder 44 to engage with the inner wall of the card groove 48 to complete the abutment fixation. By rotating the operating handle 51, the adjusting rod 52 is rotated on the top of the abutment seat 55, causing the threaded wire 53 to gradually disengage from the threaded state of the threaded groove 56. Then, under the elastic action of the abutment spring 54, the abutment seat 55 is pushed into the interior of the through groove 45, so that the abutment seat 55 abuts and fixes with the elastic element 43, preventing the elastic element 43 and the card holder 44 from disengaging from the card groove 48 under the action of external force, and improving the overall structural stability of the installation protective cover 61.
