Description

Technical Field

[0001] The present invention relates to the technical field of valves, and more particularly to a novel pressure-resistant electric stop valve. Background Art

[0002] When the stop valve is closed, pressure must be applied to the disc to prevent leakage from the sealing surface. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem must be large, otherwise the valve stem will bend. When the existing traditional stop valve is used in pipelines such as cross-way, it usually causes single operation and the slurry of the previous liquid will remain at the stop point.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] In the description of this application, it should be understood that the terms "middle", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings.

Therefore, they cannot be understood as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0043] In addition, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0044] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature. Specific implementation method one:

[0046] like Figure 1 and Figure 2 As shown, a new type of pressure-resistant electric stop valve includes a four-way pipe 1, the transverse pipe of the four-way pipe 1 is the main pipe, the longitudinal pipe of the four-way pipe 1 is the branch pipe, and the symmetrical branch pipes are respectively connected to two valve brackets 2; a transverse combination driver 3 and a longitudinal combination driver 4 are provided in the valve bracket 2, the transverse combination driver 3 drives the sealing platform 5 to combine, and the longitudinal combination driver 4 drives the sealing platform 5 to be added to the main pipe of the four-way pipe 1 to cut off and divert the flow.

[0047] The working principle and beneficial effects of this embodiment are as follows: two valve brackets 2 are installed and used on the symmetrical branch pipes on the four-way pipe 1, and a horizontal combination driver 3 and a vertical combination driver 4 are installed and used on the two valve brackets 2 respectively, and then through transmission and connection, the horizontal combination driver 3 and the vertical combination driver 4 drive the sealing platform 5 in combination. When it is necessary to divide a main flow into three branches, the horizontal combination driver 3 is retracted to separate and retract the combined sealing platform 5 into the valve bracket 2, so that the four-way pipe 1 is unobstructed; when the stop valve needs to be used for full windshield assembly, the horizontal combination driver 3 drives the sealing platform 5 to assemble, and the vertical combination driver 4 drives the assembled sealing platform 5 to be symmetrically plugged upward, thereby achieving the situation where all three pipes are blocked;

[0048] When the main pipeline is used, the transverse combined driver 3 drives the sealing platform 5 to be assembled, and the longitudinal combined driver 4 drives the assembled sealing platform 5 upward to a position parallel to the pipeline for blocking. After completion, the sealing platform 5 is separated to discharge the accumulated liquid after the blocking process.

[0049] When one of the two branch pipes needs to be used, the transverse combination driver 3 on the opposite side drives the sealing platform 5 to combine, and then the longitudinal combination driver 4 drives the combined sealing platform 5 upward to insert it into the pipe, blocking the outlet main pipe and the branch pipe extending from it, thereby realizing the use of symmetrical branch pipes;

[0050] The same applies to using any two pipes;

[0051] At the same time, by combining the use of the sealing platform 5, the accumulation of accumulated liquid can be avoided; at the same time, different forms of extended use can be used to prevent the accumulation of accumulated liquid, adapt to the flow in different directions of the one-way pipeline, and carry out the installation and disassembly combination of the sealing platform 5.

The gear shaft 7 drives two connecting bevel gear shafts 8 to rotate respectively at both ends of the valve bracket 2 through bevel gear meshing. The two connecting bevel gear shafts 8 respectively mesh and drive two bevel gear threaded cylinders 9 to rotate on the valve bracket 2;

[0057] The two bevel gear threaded cylinders 9 are respectively connected to the two propulsion sealing screws 10 through threaded fit, and the two propulsion sealing screws 10 are respectively connected to the valve bracket 2 through sealing thread fit;

[0060] The working principle and beneficial effects of this embodiment are as follows: the lateral drive servo motor 6 is controlled by the controller to automatically receive signals, and the lateral drive servo motor 6 drives the gear shaft 7 to rotate in the valve bracket 2 through the coupling. The rotating gear shaft 7 drives the two connecting bevel gear shafts 8 to rotate at the two ends of the valve bracket 2 respectively through the bevel gear meshing, thereby causing the two rotating connecting bevel gear shafts 8 to respectively mesh and drive the two bevel gear threaded cylinders 9 to rotate on the valve bracket 2; the two bevel gear threaded cylinders 9 rotating on the valve bracket 2 are respectively connected to the two advancing sealing screws 10 through threaded engagement, and the two advancing sealing screws 10 are respectively connected to the two ends of the valve bracket 2 through sealing thread engagement, and the interiors of the two advancing sealing screws 10 are respectively rotatably connected to the two double-rod advancing seats 11 through the rotating disk, thereby realizing the lateral displacement and sliding of the two double-rod advancing seats 11 in the valve bracket 2, and then the connecting side slots 13 provided at the lower end of the sealing platform 5 are respectively inserted into the two connecting side insertion rods 12 for connection, thereby realizing the adjustment of the lateral use of the sealing platform 5, and at the same time, the sealing platform 5 can be retracted into the valve bracket 2 when not in use.

[0062] like Figure 1 — Figure 15 As shown, a new type of pressure-resistant electric stop valve, the sealing platform 5 is symmetrically arranged, and the lower end of the sealing platform 5 is provided with a connecting side slot 13, which is inserted into the two connecting side plug rods 12;

[0063] A longitudinal connecting rod 14 for connecting the longitudinal combined drive 4 is fixed to the lower end of the sealing platform 5;

[0064] The symmetrical sealing platforms 5 are sealed and plugged into each other.

[0065] The working principle and beneficial effects of this embodiment are as follows: the connecting side slots 13 are inserted into the two connecting side insertion rods 12 to facilitate the transverse connection and drive of the symmetrical sealing platforms 5 for assembly; the longitudinal connecting rods 14 at the lower ends of the sealing platforms 5 are used to connect and connect the longitudinal combination drivers 4, and the longitudinal drive is performed by connecting the longitudinal combination drivers 4;

[0066] The symmetrical sealing platforms 5 are sealed and plugged into each other, and a labyrinth-like seal is achieved by sealing and plugging the sealing platforms 5 together, and the combined sealing ring 25 used for the combined sleeve connection of the outer wall is used for effective sealing and blocking, and then the combined sealing ring 25 is squeezed on the inner wall of the pipe to achieve effective sealing and blocking. Specific implementation method five:

[0068] like Figure 1 — Figure 15 As shown, a new type of pressure-resistant electric stop valve, the outer wall of the sealing platform 5 is wrapped with a combined sealing ring 25, the combined sealing rings 25 on the symmetrical sealing platforms 5 are symmetrically arranged, and the symmetrical combined sealing rings 25 are sealed and plugged into each other.

[0069] The working principle and beneficial effects of this embodiment are as follows: the symmetrical sealing platform 5 is in a combined shape, and the symmetrical combined sealing ring 25 is also in a combined shape, which makes it convenient to combine and separate for use. At the same time, the combined combined sealing ring 25 is squeezed on the inner wall of the pipe, thereby achieving effective sealing and blocking on the inner wall of the pipe.

The outer shell of the spring limit frame 17 is provided with a spring 19, and the spring 19 is arranged between the sealing platform 5 and the sealing seat 15.

[0072] The working principle and beneficial effects of this embodiment are as follows: the lower ends of the symmetrical sealing platforms 5 are sealed and inserted into each other, wherein a sealing seat 15 is provided on the sealing platform 5 on the side close to the outlet end of the main pipeline through a spring limiting frame 17, a spring shaft 18 and a spring 19. The spring limiting frame 17, the spring shaft 18 and the spring 19 are protected by a longitudinal seal to prevent water from entering and affecting the service life; the sealing seat 15 is elastically squeezed longitudinally on the sealing platform 5 through the spring limiting frame 17, the spring shaft 18 and the spring 19; and the sealing seat 15 can be used to block the stop valve. At the same time, the one-way use of the sealing seat 15 can achieve the opposite side diversion and main pipeline blocking; and the use can be switched according to different usage scenarios;

[0073] At the same time, it can be extended for use, and the end plate sealing combination on the valve bracket 2 is convenient for disassembly, and then the sealing platform 5 is convenient for replacement. Models with sealing seats 15 in different directions can be selected to achieve adjustment of the switching direction of the main pipeline flow; or models without using the sealing seat 15 can be selected, so that the valve can be switched inside the pipeline without liquid accumulation, thereby preventing slurry from hanging on the wall; at the same time, the device is convenient for disassembly and switching of parts.
