Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to an electromagnetic valve with an easy-to-plug three-way connector. Background Technology
[0002] A solenoid valve is an automated control element that uses electromagnetic force to control the switching of fluid pathways. It is widely used in industrial and civilian fields such as pneumatics, hydraulics, water treatment, and gas control. Its core feature is that it uses electromagnetic signals to switch pathways between interfaces, thereby precisely controlling the flow, direction, or pressure of fluids.
[0003] Currently, some solenoid valves on the market increase the connection path by connecting a tee connector to one of their terminals. However, the external tee connector uses a traditional clamp-fastening and plug-and-play method. During connection, the operator must place the clamp on the hose and the solenoid valve connector, then tighten the clamp bolts with tools. This process requires not only ensuring accurate clamp positioning but also precise control of the tightening force, making the operation cumbersome and demanding in terms of operating space. Disassembly requires the reverse process: loosening the bolts and removing the clamp, making the entire process time-consuming and labor-intensive. In confined spaces or scenarios with multiple tee connectors densely installed, tool access is limited, significantly increasing the difficulty of operation. Utility Model Content
[0004] The purpose of this invention is to provide a solenoid valve with an easy-to-plug tee connector, aiming to solve the problem that during connection, operators must place a clamp on the hose and the solenoid valve connector, and then tighten the clamp bolts with tools. This process requires not only ensuring accurate clamp positioning but also precise control of tightening force, making the operation cumbersome and demanding in terms of operating space. When disassembly is needed, the process must be reversed: loosening the bolts and removing the clamp, making the entire process time-consuming and laborious. In confined spaces or scenarios with multiple tee connectors densely installed, tool access is limited, significantly increasing the difficulty of operation.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a solenoid valve with an easy-to-plug three-way connector, comprising a solenoid valve, wherein a first connector is screwed onto one side of the solenoid valve, the lateral end of the first connector is connected to a second connector, a third connector is connected to the bottom of the first connector and the second connector, and a locking bolt is screwed into the opening of the second connector.
[0006] The top of the locking bolt has a frustum groove, and an air column is installed inside the frustum groove. A set of positioning rods are installed at equal intervals on the bottom outer wall of the air column, and the other end of the positioning rod is inserted into the inner wall of the second connector.
[0007] In order to ensure that the air column can be stably installed inside the second connector, as a solenoid valve with an easy-to-plug three-way connector of this utility model, a ring of insertion holes is opened on the inner wall of the second connector near the bottom.
[0008] In order to allow the airflow in the second connector to flow through the air column to the connected air pipe, as a solenoid valve with an easy-to-plug three-way connector of this utility model, preferably, the interior of the air column is a hollow structure, and a set of through holes are equally spaced on the outer wall of the air column, and the through holes connect the interior and exterior of the air column, and the bottom diameter of the frustum groove is smaller than the bottom diameter of the air column.
[0009] In order to ensure that the air column can smoothly drive the positioning rod into the second connector during installation, as a solenoid valve with an easy-to-plug three-way connector of this utility model, preferably, a spring is movably installed inside the end of the positioning rod away from the air column, one end of the spring is fixedly connected to the inner wall of the positioning rod, the other end of the spring is fixedly connected to one end of the telescopic column, and the other end of the telescopic column is fixedly connected to a plug.
[0010] The positioning rod is connected to the socket via a plug, and the internal dimensions of the socket are adapted to the dimensions of the plug. The minimum horizontal and vertical length between the plug and the positioning rod is adapted to the inner wall dimensions of the second connector.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] To use, first pass the hose plug to be connected through the frustum groove, then firmly insert the hose plug into the outer wall of the air column. Next, screw the locking bolt into the corresponding air outlet, exhaust port, or air inlet. As the locking bolt is pushed in further, the frustum groove will gradually press against the outer wall of the hose plug. When the locking bolt is fully locked, the hose plug will be firmly pressed against the outer wall of the air column by the tightening action of the locking bolt. This allows for a very convenient and effective connection of the hose plug to the second connector.
[0013] To disassemble, unscrew the locking bolt from the corresponding second connector. This will release the fixing structure between the hose plug and the air column. At this point, simply pull the hose plug outward to easily remove it.
[0014] In summary, this structure allows for a very simple plug-in / plug-out mechanism for the tee connector during practical use. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1-4 The present invention provides the following technical solution: a solenoid valve with an easy-to-plug three-way connector, including a solenoid valve 1, a first connector 2 screwed to one side of the solenoid valve 1, a second connector 3 at the lateral end of the first connector 2, a third connector 4 communicating with the bottom of the first connector 2 and the second connector 3, and a locking bolt 5 screwed into the opening of the second connector 3.
[0023] The first connector 2, the second connector 3, and the third connector 4 are an integrated structure. The first connector 2, the second connector 3, and the third connector 4 constitute a three-way connector. In use, the three-way connector is connected to the solenoid valve 1 through the first connector 2.
[0024] The top of the locking bolt 5 has a frustum groove 6 through which a gas column 7 is installed. A set of positioning rods 8 are installed at equal intervals on the bottom outer wall of the gas column 7. The other end of the positioning rod 8 is inserted into the inner wall of the second connector 3.
[0025] In this design, the solenoid valve 1 is connected to the tee connector via the first connector 2; the tee connector can be connected to the external hose via the second connector 3 and the third connector 4.
[0026] Preferably, a ring of insertion holes 31 is formed on the inner wall of the second connector 3 near the bottom.
[0027] When the air column 7 is installed inside the second connector 3, the plug 83 at one end of the positioning rod 8 is retracted into the positioning rod 8 by the compression during docking. Thus, the air column 7 can drive the positioning rod 8 to be installed into the corresponding second connector 3.
[0028] During installation, the downward trajectory of the positioning rod 8 should be aligned with the corresponding socket 31. When the air column 7 moves to the appropriate position, the plug 83 will be reset, allowing the plug 83 to be inserted into the corresponding socket 31, and the air column 7 can then be installed inside the second connector 3.
[0029] Preferably, a spring 81 is movably installed inside the end of the positioning rod 8 away from the air column 7. One end of the spring 81 is fixedly connected to the inner wall of the positioning rod 8, and the other end of the spring 81 is fixedly connected to one end of the telescopic column 82. The other end of the telescopic column 82 is fixedly connected to a plug 83.
[0030] The positioning rod 8 is connected to the socket 31 via the plug 83, and the internal dimensions of the socket 31 are adapted to the dimensions of the plug 83. The minimum horizontal and vertical length between the plug 83 and the positioning rod 8 is adapted to the inner wall dimensions of the second connector 3.
[0031] In actual use, the hose plug will first pass through the frustum groove 6, and then be inserted into the outer wall of the air column 7. After the hose plug is initially inserted into the outer wall of the air column 7, the through hole at the narrower part of the upper end of the air column 7 is inside the hose plug, so that the airflow can flow smoothly through the hose during use.
[0032] Simultaneously, after the hose plug is initially connected to the air column 7, the locking bolt 5 is screwed into the corresponding second connector 3. As the locking bolt 5 continues to penetrate, the frustum groove 6 will gradually move towards the area with the larger diameter of the air column 7. Finally, under the action of the locking bolt 5, the frustum groove 6 will firmly press and fix the hose plug to the outer wall of the air column 7, thus completing the function of locking the hose plug connection.
[0033] Preferably, a spring 81 is movably installed inside the end of the positioning rod 8 away from the air column 7. One end of the spring 81 is fixedly connected to the inner wall of the positioning rod 8, and the other end of the spring 81 is fixedly connected to one end of the telescopic column 82. The other end of the telescopic column 82 is fixedly connected to a plug 83.
[0034] The positioning rod 8 is connected to the socket 31 via the plug 83, and the internal dimensions of the socket 31 are adapted to the dimensions of the plug 83. The minimum horizontal and vertical length between the plug 83 and the positioning rod 8 is adapted to the inner wall dimensions of the second connector 3.
[0035] As the air column 7 moves, the positioning rod 8 moves downwards along with the plug 83. When the plug 83 moves to the position of the second connector 3, the spring 81 pushes the telescopic column 82 to reset. When the telescopic column 82 resets, it squeezes the plug 83 into the socket 31, thus fixing the air column 7 inside the second connector 3.
[0036] In practical use, first pass the hose plug to be connected through the frustum groove 6, and then firmly insert the hose plug into the outer wall of the air column 7. Next, screw the locking bolt 5 into the second connector 3. As the locking bolt 5 is pushed deeper, the frustum groove 6 will gradually press against the outer wall of the hose plug. When the locking bolt 5 is fully locked, the hose plug will be firmly pressed against the outer wall of the air column 7 under the tightening action of the locking bolt 5. This allows for a very convenient and effective connection of the hose plug to the solenoid valve 1.
[0037] When disassembling, unscrew the locking bolt 5 from the second connector 3. This will release the fixing structure between the hose plug and the air column 7. At this time, simply pull the hose plug outward to easily pull it out.
[0038] In summary, this structure allows for a very simple plug-in / plug-out mechanism for the tee connector during practical use.
[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
