Description

Technical Field

[0001] This utility model relates to the technical field of modular air conditioning units, specifically to an electric two-way valve for modular air conditioning units. Background Technology

[0002] The electric two-way valve is a supporting product for central air conditioning fan coil units. It consists of two parts: a driver and a valve body. The driver is driven by a synchronous motor and has spring return and manual valve opening lever operation functions.

[0003] Most electric two-way valves on the market are connected to water pipes via flanges. Flange connections offer good sealing, but they typically require two flanges to be fitted together and secured with multiple bolts. Disassembling an electric two-way valve requires operating multiple bolts, making disassembly inconvenient. Furthermore, the disassembled bolts are difficult to store and are prone to loss. Utility Model Content

[0004] The purpose of this invention is to provide a modular electric two-way valve for air conditioning units that can be quickly installed and disassembled, facilitating regular maintenance of the air conditioning unit.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device includes a valve body, a valve tube connected to the bottom of the valve body, telescopic tubes bonded to both ends of the valve tube, a connecting tube bonded to the end of the telescopic tube away from the valve tube, a groove provided at the other end of the connecting tube, the groove being located near the end of the connecting tube, an annular rubber plate fixed to the bottom of the groove, an abutment member connected to the annular rubber plate facing the groove, several abutment members being provided along the circumference of the annular rubber plate, a rotating drive ring fixed to the end of the abutment member away from the annular rubber plate, the rotating drive ring being rotatably connected inside the groove.

[0007] Furthermore, the abutting element includes a fixed tube fixed to the inner wall of the rotating drive ring, and a telescopic head is slidably connected inside the fixed tube, with the end of the telescopic head away from the fixed tube being arc-shaped.

[0008] By adopting the above technical solution, the arc setting can prevent the ring-shaped rubber sheet from being damaged when it is bumped.

[0009] Furthermore, an annular support plate is fixed inside the groove, and there is a gap between the annular support plate and the annular rubber plate.

[0010] The above technical solution provides space for the annular rubber plate to reset, increases the stability of the inner wall of the groove, and prevents the groove from being squeezed and tilted after long-term use.

[0011] Furthermore, the annular support plate has through holes on its side, and a number of through holes are provided along the circumference of the annular support plate, the number of through holes being the same as the number of abutting parts.

[0012] By adopting the above technical solution and setting up multiple points of contact, the installation stability is further improved.

[0013] Furthermore, a spring is fixed to the end of the telescopic head facing the fixed tube, and the spring is fixed to the inner wall of the fixed tube away from the end of the telescopic head.

[0014] By adopting the above technical solution, the locking tightness is improved, making it easier to perform regular maintenance on the air conditioning unit.

[0015] Furthermore, the annular adhesive sheet is double-layered and hollow inside.

[0016] The above technical solution uses a double-layered, hollow interior to further increase the deformation of the annular rubber sheet after the telescopic head comes into contact with it, thereby increasing the force with which the annular rubber sheet presses tightly against the outside of the external pipe.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. A connecting pipe is used, which is connected to the external pipe by plugging in. This avoids the use of traditional flange bolt fixing method, which is convenient for installation and reduces costs.

[0019] 2. A ring-shaped rubber plate is used. After insertion, the ring-shaped rubber plate contacts the surface of the external pipe, which increases the friction between the two and improves the installation stability.

[0020] 3. A rotating drive ring is adopted. To further tighten the lock, the rotation of the drive ring drives the telescopic head to enter through the through hole and contact the annular rubber plate, thereby improving the degree of tightening and facilitating regular maintenance of the air conditioning unit.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] 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.

[0028] Please see Figure 1-3 The present invention provides a technical solution comprising: a valve body 1, a valve tube 2 connected to the bottom of the valve body 1, telescopic tubes 3 bonded to both ends of the valve tube 2, a connecting tube 4 bonded to the end of the telescopic tube 3 away from the valve tube 2, a groove 5 provided at the other end of the connecting tube 4, the groove 5 being located near the end of the connecting tube 4, an annular rubber plate 6 fixed at the bottom of the groove 5, an abutment member connected to the end of the annular rubber plate 6 facing the groove 5, several abutment members being provided along the circumference of the annular rubber plate 6, a rotating drive ring 7 fixed to the end of the abutment member away from the annular rubber plate 6, the rotating drive ring 7 being rotatably connected inside the groove 5.

[0029] The inner wall of the annular rubber plate 6 is flush with the inner wall of the connecting pipe 4. When connecting to an external pipe, the annular rubber plate 6 contacts the outer wall of the external pipe.

[0030] The contacting element includes a fixed tube 8 fixed on the inner wall of the rotating drive ring 7, and a telescopic head 9 is slidably connected inside the fixed tube 8. The end of the telescopic head 9 away from the fixed tube 8 is rounded.

[0031] The fixed tube 8 is fixedly connected to the rotating drive ring 7, which can be freely driven to rotate by external force. When the rotating drive ring 7 rotates, the fixed tube 8 rotates along the inside of the groove 5. At the same time, a spring 12 is fixed at the end of the telescopic head 9 facing the fixed tube 8. The end of the spring 12 away from the telescopic head 9 is fixed to the inner wall of the fixed tube 8. Thus, when the fixed tube 8 rotates along the inside of the groove 5, the telescopic head 9 inside the fixed tube 8 abuts against the inside of the groove 5, at which time the spring 12 is in a compressed state. Furthermore, an annular support plate 10 is fixed inside the groove 5, and there is a gap between the annular support plate 10 and the annular rubber plate 6.

[0032] The annular support plate 10 has through holes 11 on its side. Several through holes 11 are provided along the circumference of the annular support plate 10. The number of through holes 11 is the same as the number of abutting parts.

[0033] Due to the arrangement of the annular support plate 10, the telescopic head 9 actually abuts against the surface of the annular support plate 10 when the fixed pipe 8 rotates. When the telescopic head 9 moves to the position of the through hole 11, the spring 12 inside the telescopic head 9 resets, driving the telescopic head 9 to extend along the through hole 11. At this time, the front end of the telescopic head 9 abuts against the surface of the annular rubber plate 6, releasing pressure on the annular rubber plate 6, thereby pressing the inner side of the annular rubber plate 6 against the outer side of the externally connected pipe.

[0034] Meanwhile, the annular rubber plate 6 is double-layered and hollow inside, which can further increase the deformation of the annular rubber plate 6 after the telescopic head 9 comes into contact with it, thereby increasing the force of the annular rubber plate 6 pressing tightly against the outside of the external pipe.

[0035] The working principle of this utility model is as follows: In actual use, the electric two-way valve of this application is installed in the water pipe of the air conditioning unit. As a connection, it is connected to the external pipe by means of connecting pipe 4, avoiding the use of traditional flange screw fixing method. After insertion, the annular rubber plate 6 contacts the surface of the external pipe to increase the friction between the two. At the same time, in order to further lock, by rotating the drive ring 7, the telescopic head 9 is driven to enter along the through hole 11 and abut against the annular rubber plate 6, which improves the degree of locking. Since the electric two-way valve installed in the air conditioning unit needs to be disassembled and cleaned frequently to avoid internal blockage and reduced air conditioning unit operation, when disassembling, the drive ring 7 is rotated in the opposite direction to move the telescopic head 9 out of the through hole 11, and at the same time pushes the connecting pipe 4 towards the valve pipe 2 end, which can be directly disassembled, making the operation simple and improving the efficiency of subsequent maintenance.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
