Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, specifically an electric valve that can quickly switch working modes. Background Technology

[0002] An electric valve is an automated device that controls the opening and closing of a valve and regulates its operation through an electric actuator. It uses electrical energy to drive a motor, which in turn drives the valve stem through a reduction gear, thereby changing the valve opening and achieving precise control of parameters such as flow rate, pressure, and temperature of fluid media (such as liquids and gases).

[0003] In existing electric valves, the electric actuator is usually directly exposed during use, lacking an effective protective structure, and is easily damaged by external factors. Since the electric actuator is an important control structure in the electric valve, once the electric actuator is damaged, the electric valve will not be able to work properly. At the same time, the exposed electric actuator is also prone to accidental activation, which will cause the working state of the electric valve to be changed unexpectedly, greatly affecting the efficiency and safety of the electric valve.

[0004] Therefore, there is a need for an electric valve that can quickly switch operating modes to solve the problem that the exposed actuator on the electric valve in the existing technology is prone to damage or accidental activation. Utility Model Content

[0005] The purpose of this invention is to provide an electric valve that can quickly switch working modes, in order to solve the problem that the exposed actuator on the electric valve in the prior art is prone to damage or accidental activation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric valve that can quickly switch working modes, including a valve body, an electric actuator provided at the top of the valve body, a manual execution structure provided on one side of the top of the valve body, and a protective mechanism provided outside the electric actuator;

[0007] The protective mechanism includes a fixed cover and a movable cover, which are connected by hinges and both are located outside the electric actuator. A mounting block is fixedly connected to the right side of the fixed cover. The mounting block has an installation cavity inside, and T-shaped grooves are formed on both sides of the installation cavity. T-shaped sliders are slidably connected inside the T-shaped grooves. The two T-shaped sliders are mirror-symmetrically distributed, and L-shaped rods are fixedly connected to one side of their outer walls. A spring is fixedly connected between one end wall of the horizontal section of the L-shaped rod and one end wall of the installation cavity. A locking rod is fixedly connected to the other end wall of the horizontal section of the L-shaped rod. The vertical sections of the two L-shaped rods slide through one end of the outer wall of the mounting block and are fixedly connected to pressure plates. A slot communicating with the installation cavity is formed on the front outer wall of the mounting block.

[0008] It should be noted in the solution that the protective mechanism also includes a fixing plate, which is fixedly connected to the right side of the movable cover. The outer wall of the rear end of the fixing plate is fixedly connected to a plug that matches the slot. The top and bottom ends of the plug are provided with locking holes that match the locking rod.

[0009] It is worth noting that mounting clamps are provided on the outside of the connecting pipes on both sides of the valve body, and the two mounting clamps are connected to fixing seats by bolts. The top of the two fixing seats is fixedly connected to the same support frame.

[0010] Furthermore, it should be noted that the outer surface of the electric actuator is provided with a control panel, and the outer surface of the movable cover is provided with an observation window.

[0011] In a preferred embodiment, the two locking rods are respectively inserted into the corresponding locking holes, the insert block is inserted into the slot, and the support frame is fixedly connected to the fixing cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By pressing the two pressure plates simultaneously, the L-shaped rod causes the locking rod to separate from the locking hole, releasing the lock on the slot. Pulling the movable cover and rotating it exposes the electric actuator, which can then be operated via the control panel. In conjunction with the intelligent control system integrated inside the electric actuator, the working state of the electric valve can be quickly switched. The fixed and movable covers protect the electric actuator while preventing accidental activation. The operation is simple and effectively avoids the problem of exposed actuators on electric valves being easily damaged or causing accidental activation. Attached Figure Description

[0020] 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.

[0021] Example: Figures 1-5 As shown, this utility model provides a technical solution, including a valve body 1, an electric actuator 2 is provided at the top of the valve body 1, a manual actuation structure 3 is provided on one side of the top of the valve body 1, and a protective mechanism 4 is provided outside the electric actuator 2.

[0022] The protective mechanism 4 includes a fixed cover 41 and a movable cover 42. The fixed cover 41 and the movable cover 42 are connected by a hinge and are both located outside the electric actuator 2. A mounting block 43 is fixedly connected to the right side of the fixed cover 41. A mounting cavity 44 is opened inside the mounting block 43. T-shaped grooves 45 are opened on both sides inside the mounting cavity 44. T-shaped sliders 46 are slidably connected inside the T-shaped grooves 45. The two T-shaped sliders 46 are mirror-symmetrically distributed and L-shaped rods 47 are fixedly connected to one side of the outer wall. A spring 48 is fixedly connected between one end wall of the horizontal section of the L-shaped rod 47 and one end wall inside the mounting cavity 44. A locking rod 49 is fixedly connected to the other end wall of the horizontal section of the L-shaped rod 47. The vertical sections of the two L-shaped rods 47 slide through one end of the outer wall of the mounting block 43 and are fixedly connected to a pressure plate 410. A slot 411 communicating with the mounting cavity 44 is opened on the front outer wall of the mounting block 43.

[0023] Specifically, pressing the two pressure plates 410 simultaneously moves the corresponding L-shaped rods 47. With the cooperation of the T-shaped slide groove 45 and the T-shaped slider 46, the L-shaped rods 47 slide and move the locking rods 49. When the two locking rods 49 are far apart from each other, they separate from the locking holes 414, thereby releasing the lock on the plug block 413, so that the electric actuator 2 can be exposed, making it convenient for the operator to switch the working mode of the electric valve.

[0024] Further as Figure 5As shown, it is worth noting that the protective mechanism 4 also includes a fixing plate 412, which is fixedly connected to the right side of the movable cover 42. The outer wall of the rear end of the fixing plate 412 is fixedly connected to a plug 413 that is compatible with the slot 411. The top and bottom ends of the plug 413 are provided with locking holes 414 that are compatible with the locking rod 49.

[0025] Specifically, when both locking rods 49 are separated from their corresponding locking holes 414, the insert block 413 is not restricted, and the fixed plate 412 is pulled to rotate the movable cover 42. The insert block 413 moves out of the slot 411, and the movable cover 42 separates from the fixed cover 41, thus exposing the electric actuator 2.

[0026] Further as Figure 1 and Figure 3 As shown, it is worth noting that both sides of the valve body 1 are equipped with mounting clamps 5 on the outside of the connecting pipes. Both mounting clamps 5 are connected to fixing seats 6 by bolts, and the top of the two fixing seats 6 are fixedly connected to the same support frame 7.

[0027] Specifically, when the fixed cover 41 or the movable cover 42 is damaged, after removing the bolts used to fix the mounting clamp 5 and the fixed seat 6, the fixed seat 6 can be removed from the valve body 1, thereby removing the fixed cover 41 and the movable cover 42 from the electric actuator 2 for easy replacement.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the outer surface of the electric actuator 2 is provided with a control panel 8, and the outer surface of the movable cover 42 is provided with an observation window 9.

[0029] Specifically, after the electric actuator 2 is exposed, the operator can quickly switch the working state of the electric valve by operating the control panel 8 and working with the intelligent control system integrated inside the electric actuator 2. Under normal operating conditions of the electric valve, the current working mode, valve status and other information can be viewed through the observation window 9.

[0030] Further as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the two locking rods 49 are inserted into the corresponding locking holes 414, the insert block 413 is inserted into the slot 411, and the support frame 7 is fixedly connected to the fixing cover 41.

[0031] Specifically, the two locking rods 49 are inserted into the corresponding locking holes 414 to lock the insert 413. The insert 413 is inserted into the slot 411, so that the fixed cover 41 and the movable cover 42 are connected. The support frame 7 is fixedly connected to the fixed cover 41. After the mounting hoop 5 and the fixed seat 6 are disassembled and separated, the fixed seat 6 is removed from the valve body 1, thereby realizing the disassembly of the fixed cover 41 and the movable cover 42.

[0032] In summary: During use, the electric valve protects the electric actuator 2 through the cooperation of the fixed cover 41 and the movable cover 42. When a rapid switching of the electric valve's working mode is required, both pressure plates 410 are pressed simultaneously. Under pressure, the two pressure plates 410 push the corresponding L-shaped rod 47 to move. The L-shaped rod 47 drives the locking rod 49 to separate from the locking hole 414, releasing the lock on the slot 411. At this time, the movable cover 42 is pulled and rotated to expose the electric actuator 2. The operator can operate it through the control panel 8. With the intelligent control system integrated inside the electric actuator 2, the working state of the electric valve can be quickly switched to fully open, fully closed, or the flow rate can be adjusted. After completing the switching of the working mode, the above operations are reversed to connect the fixed cover 41 and the movable cover 42, protecting the electric actuator 2 while preventing accidental activation. The operation is simple and effectively avoids the problem of the exposed actuator on the electric valve being easily damaged or causing accidental activation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
