Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking correction equipment technology, and more specifically, it relates to a handle valve. Background Technology
[0002] In the papermaking process, the dryer wire (also known as the drying wire) is an important component of the drying section of the paper machine. It is usually made of polyester or metal materials and plays a key role in conveying wet paper sheets, assisting in dehydration, and maintaining the flatness of the paper.
[0003] In existing technologies, dry wire (or ring wire) operates under high temperature, high humidity and high tension conditions for a long time. Due to factors such as equipment installation errors, roller wear, uneven tension distribution or production speed fluctuations, it is difficult for it to maintain a centered position during operation, which may lead to deviation, resulting in paper wrinkles, uneven dehydration or even paper breakage, which seriously affects production efficiency and finished product quality.
[0004] Therefore, a handle valve is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a handle valve to solve the problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A handle valve includes a housing, a valve core inside the housing, a handle extending from the valve core rotatably connected to the valve core, a limiting component for preventing the handle from rotating detachably connected to both the housing and the valve core, and a sensor corresponding to the handle detachably connected to the valve core, one end of the sensor being located inside the valve core, and the other end of the sensor penetrating through the housing to the outside.
[0008] The technical solution of this utility model is further configured as follows: an extension is fixedly connected to one end of the handle located inside the valve core, and a pin is also hinged to the other end of the handle located inside the valve core via a connecting plate. The two ends of the connecting plate are rotatably connected to the valve core and the pin, respectively. The limiting assembly includes two limiting screws, which are oriented in opposite directions and respectively toward the extension and the pin.
[0009] The technical solution of this utility model is further configured as follows: the valve core has a cavity through which it passes, the rotation center of the handle is located in the cavity, the valve core also has a through hole through which it passes, and the pin and the corresponding limiting screw both have their opposite ends located in the through hole.
[0010] The technical solution of this utility model is further configured such that: a torsion spring is sleeved at the rotating connection of the handle, and both ends of the torsion spring extend outward and are engaged with the valve core.
[0011] The technical solution of this utility model is further configured such that a baffle is fixedly connected to the end of the handle away from the valve core.
[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0013] By setting the upper limit assembly on the housing and valve core to limit the rotation range of the handle, the deviation of the dry net can be applied to the handle by the baffle, causing the handle to rotate. At this time, two limit screws are used to limit the extreme position of the handle deflection. During this process, the sensor senses the deflection of the handle and outputs an electrical signal to prompt and assist in the dry net correction work. After the correction is completed, the handle can be deflected back to its original position under the action of the torsion spring, allowing the baffle to monitor whether the dry net is deviated at all times.

[0019] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example
[0020] refer to Figures 1 to 4As shown, this utility model provides a handle 3 valve, including a housing 1, a valve core 2 inside the housing 1, a handle 3 extending from the inside of the valve core 2 is rotatably connected to the valve core 2, a baffle 12 is fixedly connected to the end of the handle 3 away from the valve core 2, a limiting component for preventing the handle 3 from rotating is detachably connected to both the housing 1 and the valve core 2, and a sensor 4 corresponding to the handle 3 is detachably connected to the valve core 2, one end of the sensor 4 is located inside the valve core 2, and the other end of the sensor 4 penetrates through the housing 1 to the outside.
[0021] refer to Figures 1 to 4 As shown, the valve core 2 has a cavity 9 through which it passes. The rotation center of the handle 3 is located inside the cavity 9. An extension 5 is fixedly connected to one end of the handle 3 inside the cavity 9. A pin 7 is also hinged to the other end of the handle 3 inside the cavity 9 via a connecting plate 6. The two ends of the connecting plate 6 are rotatably connected to the valve core 2 and the pin 7, respectively. The limiting assembly includes two limiting screws 8, which face opposite directions and are respectively positioned towards the extension 5 and the pin 7. The valve core 2 also has a through hole 10 through which it passes. The pin 7 and its corresponding limiting screw 8 face each other. One end of each part is located inside the through hole 10. With the above structure, when the handle 3 is deflected, the extension 5 may come into contact with a limiting screw 8. It may also cause the connecting plate 6 and the pin 7 to move when the handle 3 is rotated. As a result, the pin 7 moves in the horizontal direction under the restriction of the valve core 2 and comes into contact with another limiting screw 8 at the through hole 10. Thus, the maximum rotation angle of the handle 3 can be well limited by these two limiting screws 8. Furthermore, the presence of the through hole 10 prevents the pin 7 from receiving resistance from air pressure when it moves.
[0022] refer to Figure 3 and Figure 4 As shown, a torsion spring 11 is sleeved at the rotating connection of the handle 3. Both ends of the torsion spring 11 extend outward and are engaged with the valve core 2. This way, there is always a force on the handle 3 to drive it to reset. After the dry network correction is completed, the handle 3 can be reset in time to monitor whether the dry network will deviate during subsequent work.
[0023] refer to Figures 1 to 4 As shown above, by setting the upper limit assembly on the housing 1 and valve core 2 to limit the rotation range of the handle 3, the deviation of the dry net can be caused by the baffle 12 acting on the handle 3, driving the handle 3 to rotate. At this time, the two limit screws 8 are used to limit the extreme position of the handle 3 deflection. During this process, the sensor 4 senses the deflection of the handle 3 and outputs an electrical signal to prompt and assist in the dry net correction work. After the correction is completed, the handle 3 can be deflected and reset under the action of the torsion spring 11, so that the baffle 12 can monitor whether the dry net is deflected at all times.
[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
