[0022] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.
[0023] Example 1: Figure 1-2 As shown, a soft-sealed valve with a switch indicator protective cover, the soft-sealed valve includes a valve body 1 and a valve cover 16 that are connected to each other, the valve cover 16 is located on the top of the valve body 1, and the switch indicator 7 is installed on the valve cover 16, the switch indicator protective cover includes a protective cover arranged at the valve cover 16 and suitable for partially opening, the open part of the protective cover is made of transparent material, suitable for directly observing the switch indicator 7, the protective cover wraps the switch indicator 7 in the closed state, and a cleaning component is provided on the protective cover, which is suitable for cleaning the open part when the open part is opened.
[0024] like Figure 3 As shown, the protective cover includes a fixed cover 3 and a movable cover 4 as an opening part. The movable cover 4 is suitable for rotating into the fixed cover 3 to open the protective cover.
[0025] like Figure 4 As shown, an opening is provided at one end of the fixed sleeve 3, and the movable sleeve 4 is suitable for rotating through the opening to enter the fixed sleeve 3, and a negative pole magnet 6 is provided at the other end of the fixed sleeve 3. When the protective cover is closed, the movable sleeve 4 is provided with a positive pole magnet 5 at the end in contact with the negative pole magnet 6. The positive pole magnet 5 and the negative pole magnet 6 are fitted together under the action of magnetic attraction, and the fitting part is sealed.
[0026] like Figure 3As shown, a rotatable valve stem 2 is provided on the valve cover 16, and the movable sleeve 4 is rotatably connected to the valve cover 16 through a bearing 15. The rotation center of the movable sleeve 4 is connected to a driven gear 9, and a driving gear 10 is rotatably installed on the top of the fixed sleeve 3. The driving gear 10 and the driven gear 9 are meshed and connected. The driving gear 10 is driven to rotate by the driving device 11. The driving gear 10 is suitable for driving the movable sleeve 4 to rotate to open the protective cover.
[0027] like Figure 5 As shown, the cleaning component includes two cleaning portions 12 arranged at the opening, and the cleaning portions 12 are suitable for cleaning the inner and outer surfaces of the movable sleeve 4 when the movable sleeve 4 rotates to open the protective cover.
[0028] The working principle of this embodiment is as follows:
[0029] During installation, the protective cover is placed on the valve cover 16 as a whole, the top of the protective cover is sleeved on the outside of the valve stem 2, a rotating seal is set at the connection, and the bottom of the protective cover is set on the top of the connection between the valve cover 16 and the valve body 1;
[0030] The protective cover can play a sealing role, and the transparent setting of the movable sleeve 4 can observe the display on the switch indicator 7 from the outside. The switch indicator 7 senses the switch of the valve by means of an electrical signal. This part is a prior art and will not be described in detail here.
[0031] When the temperature difference between the inside and outside of the protective cover is large and the internal fogging makes it difficult to see the switch indicator 7 or the inner and outer surfaces of the movable cover 4 are dirty, the driving device 11 can be started to rotate forward to drive the active gear 10 to rotate. The active gear 10 drives the movable cover 4 to rotate into the fixed cover 3 through the engagement with the driven gear 9 and enters from the opening of the fixed cover 3. At this time, the protective cover is in an open state and the interior of the fixed cover 3 can be directly cleaned and maintained manually. At the same time, during the rotation of the movable cover 4, the inner and outer surfaces of the movable cover 4 will contact the cleaning part 12. The cleaning part 12 can directly remove the fog and scrape off the dirt on the inner and outer surfaces. The cleaning part 12 can be made of a flexible material such as a sponge. After cleaning, the driving device 11 is reversed to drive the movable cover 4 to reset and dock them by magnetic attraction. The docking point is sealed to ensure sealing. This part realizes automatic cleaning of the visible part through the openable setting of the protective cover part, which improves the convenience of use, avoids obstruction of observation of the switch indicator 7, and solves the problem of internal fogging.
[0032] Example 2: Figure 5As shown, this embodiment further includes the following structure on the basis of the first embodiment: a rotating seat 8 is connected to the valve cover 16, the lower end of the movable sleeve 4 is slidably set on the rotating groove of the rotating seat 8, and a retractable sealing gasket 13 is respectively provided on both sides of the rotating groove of the rotating seat 8. The lower end of the movable sleeve 4 squeezes the two sealing gaskets 13 to achieve sealing.
[0033] like Figure 2 As shown, a placement plate 14 is connected to the valve cover 16, and a switch indicator 7 is placed inside the placement plate 14. The switch indicator 7 can monitor the switching state of the entire valve.
[0034] The working principle of this embodiment is as follows:
[0035] The lower end of the movable sleeve 4 is slidably set on the rotating groove of the rotating seat 8, and a retractable sealing gasket 13 is set inside the rotating seat 8. The sealing gasket 13 can be connected to the inside of the rotating seat 8 by elastic materials such as springs. The two ends of the sealing gasket 13 are set to an inclination angle setting. When the movable sleeve 4 is converted from an open form to a closed form, the movable sleeve 4 moves inside the rotating seat 8 and is inserted between the two sealing gaskets 13 while moving. The setting of the inclination angle can make the movable sleeve 4 easier to insert between the two sealing gaskets 13. After insertion, the movable sleeve 4 will squeeze the sealing gasket 13. The reaction force generated after the sealing gasket 13 is squeezed cooperates with the squeezing force to achieve sealing between the sealing gasket 13 and the movable sleeve 4. This part replaces the traditional manually adjusted squeezing by automatic squeezing to achieve the sealing effect.
[0036] A placement plate 14 is provided on the valve cover 16 for placing a switch indicator.
[0037] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
