Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically relating to an anti-misoperation solenoid valve installation guide. Background Technology

[0002] A flange solenoid valve is a pilot-operated, secondary-opening solenoid valve consisting of two main components: a secondary valve and a main valve. Its working principle is mainly based on the interaction between electromagnetic force and fluid pressure.

[0003] When installing a flanged solenoid valve, it is necessary to ensure that the flange of the solenoid valve is aligned with the flange of the pipeline. At the same time, when tightening the flange connection with bolts, avoid over-tightening the bolts, which may cause deformation or damage to the flange gasket, and thus lead to serious consequences due to small leaks. Utility Model Content

[0004] The purpose of this invention is to provide a guide for installing a solenoid valve to prevent misoperation, which can guide the solenoid valve before tightening to avoid installation errors.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An anti-misoperation solenoid valve installation guide includes a solenoid valve, a pipe for guiding water flow, and a flange plate for connecting the solenoid valve and the pipe. A first locking post and a second locking post are respectively inserted into the through holes on the flange plate of the solenoid valve and the pipe, and the first locking post and the second locking post are locked together.

[0007] One end of the first buckle post is provided with an opening, and a retaining ring is engaged in the opening, and the retaining ring is provided with an opening;

[0008] One end of the second buckle post is provided with a protrusion, and the outer wall of the protrusion is provided with a trapezoidal groove;

[0009] The trapezoidal slot corresponds to the retaining ring, the protrusion corresponds to the opening, and a magnet is provided in the opening and the protrusion. The first and second retaining posts attract each other under the action of the magnet.

[0010] The thickness of the middle part of the retaining ring is greater than the thickness of the ring at the opening position, and the connection is linearly transitioned.

[0011] The first and second snap-fit ​​posts are available in various universal sizes, and the first and second snap-fit ​​posts are compatible with the connection holes of the flange plate.

[0012] The outer diameter of the first snap-fit ​​post is not greater than the size of the connection hole of the flange plate;

[0013] The outer diameter of the second snap-fit ​​post is not greater than the size of the connection hole of the flange plate, and a nut is threaded on the outer side of the second snap-fit ​​post.

[0014] Multiple magnetic rings are provided on the outer side of the first buckle post, and the magnetic rings are embedded in the first buckle post;

[0015] A magnetic ring is embedded in the nut on the side closest to the flange plate.

[0016] The first and second snap-fit ​​posts of different specifications are all provided with threaded holes of the same specification, and are respectively threaded with male and female threads;

[0017] The retaining ring is disposed on the female buckle, and the trapezoidal retaining groove is disposed on the female buckle.

[0018] The retaining ring is engaged in the annular groove of the hole at one end of the first retaining post, and the outer diameter of the retaining ring is smaller than the inner diameter of the annular groove of the hole at one end of the first retaining post.

[0019] The technical effects achieved by this utility model are as follows:

[0020] This utility model provides support for the sealing gasket at the end of the flange plate through the first and second snap-fit ​​posts on the flange plate. At the same time, the snap-fit ​​posts provide support and guidance for the solenoid valve after being engaged. This can prevent the sealing gasket on the flange plate from folding due to uneven force when installing and tightening bolts, which would affect the sealing effect and the service life of the sealing gasket.

[0021] This utility model integrates the retaining ring and trapezoidal groove onto the male and female fasteners respectively. During use, the appropriate first and second fastening posts are selected according to the through hole size of the flange plate, and the male and female fasteners are screwed onto the first and second fastening posts respectively. The operation is convenient and quick, while reducing production costs. Attached Figure Description

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0032] like Figures 1 to 7 As shown, an anti-misoperation solenoid valve installation guide includes a solenoid valve 1, a pipe 2 for guiding water flow, and a flange plate 3 for connecting the solenoid valve 1 and the pipe 2. A first locking post 4 and a second locking post 6 are respectively inserted into the through holes on the flange plate 3 of the solenoid valve 1 and the pipe 2, and the first locking post 4 and the second locking post 6 are locked together.

[0033] One end of the first buckle post 4 is provided with an opening, and a retaining ring 5 is engaged in the opening. The retaining ring 5 is provided with an opening.

[0034] The second buckle post 6 has a protrusion at one end, and a trapezoidal groove 10 is provided on the outer wall of the protrusion;

[0035] The trapezoidal slot 10 corresponds to the retaining ring 5, and the protrusion corresponds to the opening. A magnet 13 is provided in the opening and the protrusion. The first retaining post 4 and the second retaining post 6 attract each other under the action of the magnet 13.

[0036] Then, use bolts to connect the solenoid valve 1 and the flange plate 3 on the pipeline 2 according to the operating specifications.

[0037] Furthermore, a sealing gasket is provided between the flange plate 3 of the solenoid valve 1 and the pipeline 2.

[0038] Furthermore, the protrusion of the second snap-on post 6 has a circular cross-section, and the end edge is provided with a support chamfer.

[0039] Furthermore, the first locking post 4 and the second locking post 6 are spaced apart on the flange plate 3 and evenly distributed to provide better support.

[0040] Furthermore, according to the above structure, by placing the first snap-fit ​​post 4 or the second snap-fit ​​post 6 on the flange plate 3 connected to the pipe 2, and placing another one on the flange plate 3 on the solenoid valve 1, and making the first snap-fit ​​post 4 and the second snap-fit ​​post 6 correspond to each other, when the solenoid valve 1 is placed between the pipes 2, the second snap-fit ​​post 6 slides towards the side of the first snap-fit ​​post 4 under the action of magnetic force, and the protrusion squeezes the retaining ring 5, causing the retaining ring 5 to open and finally be locked in the trapezoidal retaining groove 10. The first snap-fit ​​post 4 and the second snap-fit ​​post 6 are engaged on one side. With the cooperation of multiple sets of first snap-fit ​​posts 4 and second snap-fit ​​posts 6, the solenoid valve 1 is supported and fixed, and the connection between the pipe 2 and the solenoid valve 1 is guided.

[0041] The first snap-fit ​​post 4 and the second snap-fit ​​post 6 installed on the flange plate 3 can provide support for the sealing gasket at the end of the flange plate 3. At the same time, the first snap-fit ​​post 4 and the second snap-fit ​​post 6 provide support and guidance for the solenoid valve 1 after snapping. This can prevent the sealing gasket on the flange plate 3 from folding due to uneven force when installing and tightening the bolts, which would affect the sealing effect and the service life of the sealing gasket.

[0042] See attached document Figure 5 The thickness of the middle part of the retaining ring 5 is greater than the thickness of the ring at the opening of the retaining ring 5, and the connection is linearly transitioned.

[0043] According to the above structure, when the retaining ring 5 contacts the protrusion of the second retaining post 6, the second retaining post 6 opens the opening of the retaining ring 5 under the magnetic attraction of the magnet 13 until the retaining ring 5 is inserted into the trapezoidal groove 10, thereby realizing the snap-fit ​​fixation between the first retaining post 4 and the second retaining post 6.

[0044] See attached document Figure 1 The first snap-fit ​​post 4 and the second snap-fit ​​post 6 are available in various universal sizes, and the first snap-fit ​​post 4 and the second snap-fit ​​post 6 are compatible with the connection holes of the flange plate 3.

[0045] The outer diameter of the first snap-fit ​​post 4 is not greater than the size of the connection hole of the flange plate 3;

[0046] The outer diameter of the second snap-fit ​​post 6 is not greater than the size of the connecting hole of the flange plate 3, and the outer side of the second snap-fit ​​post 6 is threaded with a nut 7.

[0047] Furthermore, the nut 7 is used to limit the second snap-fit ​​post 6. When the magnet 13 attracts the first snap-fit ​​post 4 and the second snap-fit ​​post 6 to move towards each other, the second snap-fit ​​post 6, under the limitation of the nut 7, attracts the first snap-fit ​​post 4 to move towards the side of the second snap-fit ​​post 6 until the snap ring 5 engages with the trapezoidal slot 10.

[0048] At the same time, the position of the second snap pin 6 on the flange plate 3 is adjusted by rotating the nut 7 to accommodate flange plates 3 of different thicknesses, so as to avoid a large gap between the snap ring 5 and the trapezoidal slot 10, which would prevent the snap ring 5 and the trapezoidal slot 10 from engaging under the magnetic attraction of the magnet 13.

[0049] According to the above structure, by setting up first snap-fit ​​posts 4 and second snap-fit ​​posts 6 of various specifications, the connection between solenoid valve 1 and pipeline 2 with through holes of different sizes can be accommodated.

[0050] See attached document Figure 2 and attached Figure 3 Multiple magnetic rings 9 are provided on the outer side of the first buckle post 4, and the magnetic rings 9 are embedded in the first buckle post 4;

[0051] A magnetic ring 8 is embedded in the nut 7 on the side closest to the flange plate 3.

[0052] According to the above structure, the first snap-on post 4 is magnetically attracted to the through hole of the flange plate 3 through the magnetic ring 2 9, which prevents the first snap-on post 4 from accidentally detaching. The second snap-on post 6 is magnetically attracted to the surface of the flange plate 3 through the magnetic ring 1 8, which improves the stability of the connection between the second snap-on post 6 and the flange plate 3.

[0053] Once all the fastening bolts have been installed in the remaining through holes of the flange plate 3, pull the nut 7 to pull out the first locking post 4 and the second locking post 6 as a whole, and then install the fastening bolts in the remaining through holes. The operation is convenient and quick.

[0054] See attached document Figure 3 and attached Figure 6 The first buckle post 4 and the second buckle post 6 of different specifications are all provided with threaded holes of the same specification, and are respectively threaded with a female buckle 11 and a female buckle 12.

[0055] The retaining ring 5 is set on the female buckle 11, and the trapezoidal retaining groove 10 is set on the female buckle 12.

[0056] Based on the above structure, since the structure of the retaining ring 5 and the trapezoidal groove 10 is relatively complex, and there are many specifications of the first retaining post 4 and the second retaining post 6, in order to reduce costs, the retaining ring 5 and the trapezoidal groove 10 are integrated on the male retaining post 11 and the female retaining post 12 respectively. When using, the appropriate specifications of the first retaining post 4 and the second retaining post 6 are selected according to the through hole size of the flange plate 3, and the male retaining post 11 and the female retaining post 12 are screwed onto the first retaining post 4 and the second retaining post 6 respectively, which is convenient and quick to operate.

[0057] See attached document Figure 5 The retaining ring 5 is engaged in the annular groove of the hole at one end of the first retaining post 4, and the outer diameter of the retaining ring 5 is smaller than the inner diameter of the annular groove of the hole at one end of the first retaining post 4.

[0058] According to the above structure, when the retaining ring 5 is supported, the retaining ring 5 deforms in the annular groove of the hole at one end of the first retaining post 4, and finally gets engaged in the trapezoidal retaining groove 10.

[0059] The working principle of this utility model is as follows: By placing the first snap-fit ​​post 4 or the second snap-fit ​​post 6 on the flange plate 3 connected to the pipe 2, and placing another one on the flange plate 3 on the solenoid valve 1, the first snap-fit ​​post 4 and the second snap-fit ​​post 6 correspond to each other. When the solenoid valve 1 is placed between the pipes 2, the second snap-fit ​​post 6 slides towards the first snap-fit ​​post 4 under the action of magnetic force, and the protrusion squeezes the retaining ring 5, causing the retaining ring 5 to open and finally lock into the trapezoidal retaining groove 10. The first snap-fit ​​post 4 and the second snap-fit ​​post 6 are engaged on one side. The cooperation of multiple sets of first snap-fit ​​posts 4 and second snap-fit ​​posts 6 provides support and fixation for the solenoid valve 1 and provides guidance for the connection between the pipe 2 and the solenoid valve 1. Then, the fastening bolts are installed according to the operating specifications. When the fastening bolts are installed in all the remaining through holes of the flange plate 3, the first snap-fit ​​post 4 and the second snap-fit ​​post 6 are pulled out as a whole by pulling the nut 7. Then, the remaining through holes are used to install the fastening bolts. The operation is convenient and quick.

[0060] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
