Description

Technical Field

[0001] The utility model relates to the technical field of valve joint butt fixing devices, in particular to a solenoid valve joint butt fixing device. Background Art

[0002] A solenoid valve is a control element that converts electrical energy into mechanical or electromagnetic energy and is widely used in various industrial automation control systems. The solenoid valve connector is a crucial component that connects the solenoid valve to the gas or fluid circuit, controlling the flow and direction of the gas or fluid. There are many types of solenoid valve connectors, including threaded connectors, flange connectors, and plug-in connectors.

[0003] Among them, the threaded joint needs to rotate the solenoid valve or pipe when in use, so the valve body is prone to tilt or pipe offset after installation, which requires correction and is more troublesome. The flange connection needs to tighten the bolts after alignment to ensure its airtightness, which is more cumbersome during installation and disassembly. In addition, the straight plug joint is prone to tension or torsion, resulting in failure of the connection airtightness. Therefore, in response to the above problems, a solenoid valve joint docking and fixing device is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a solenoid valve connector docking and fixing device. When installing the valve connector docking and fixing device, it is only necessary to insert the insert pipe into the inner lining pipe and the outer sleeve, and then tighten the locking cover. The operation is simple, and the locking cover is threadedly connected to the outer sleeve, which can effectively prevent the insert pipe from falling out of the slot, ensuring the reliability of the connection. In the above process, when the insert pipe is inserted, the docking protrusion and the docking groove can be combined to play a guiding and positioning role, and the valve body will not be offset, which is convenient for installation. At the same time, the engagement of the docking protrusion and the docking groove can play an anti-twist role, ensuring the firmness of the joint connection, solving the technical problems in the prior art that the valve body joint is not simple and quick enough to operate when connected and the joint connection has poor pull-out and torsion resistance.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A solenoid valve connector docking and fixing device includes a solenoid valve body, a plug connector connected to a pipe end thereof, the plug connector includes a plug tube, an anti-twist ring is provided on the outer sleeve of the plug tube, a socket connector includes an inner liner tube and an outer sleeve, a slot for the plug connector to be inserted is formed between the two, and a locking cover is sleeved on the outside of the plug connector and can be threadedly connected to the outer sleeve, wherein the anti-twist ring is provided with a plurality of docking grooves arranged in a circumferential array, and the end of the outer sleeve is fixedly provided with a plurality of docking protrusions matching the docking grooves.

[0007] Through the above-mentioned structural form, during installation, it is only necessary to insert the cannula into the inner lining tube and the outer sleeve, and then tighten the locking cover. The operation is simple, and the locking cover is threadedly connected to the outer sleeve, which can effectively prevent the cannula from falling out of the slot, ensuring the reliability of the connection. In the above process, when the cannula is inserted, the docking protrusion and the docking groove can be combined to play a guiding and positioning role, and the valve body will not be offset, which facilitates the installation work. At the same time, the engagement of the docking protrusion and the docking groove can play an anti-twisting role, ensuring the firmness of the joint connection.

[0008] In a possible implementation, the locking cover includes a cover cylinder, a rear end of which is fixedly connected to a butt ring, and an opening diameter of the butt ring is smaller than a diameter of the anti-twist ring.

[0009] Through the above structure, when the cover is tightened, the push ring will push the anti-twist ring, and at the same time, the cover applies a pulling force to the outer sleeve, which can keep the plug and the socket in a relative motion, so that the insert will not slip.

[0010] In a possible implementation, an external thread is fixedly provided on the outer wall of the outer sleeve, and an internal thread matching the external thread is provided on the inner wall of the cover tube.

[0011] The above-mentioned structural form provides the necessary structural basis for the threaded connection between the cover cylinder and the outer sleeve.

[0012] In a possible implementation, an elastic gasket is attached to the butt ring, and the elastic gasket is formed by bonding an elastic rubber gasket between two metal gaskets.

[0013] Through the above-mentioned structural form, when the counter ring squeezes the elastic gasket, it will be subjected to the external thrust of the elastic gasket, thereby causing the threads of the cover tube and the outer sleeve to squeeze each other and generate friction, thereby improving the anti-loosening ability of the threaded connection.

[0014] In a possible implementation, the cover tube and the docking protrusion are provided with communicating threaded holes, wherein the threads are connected with anti-loosening fasteners.

[0015] With the above-mentioned structural form, after the locking cover is tightened, the anti-loosening fastener can be inserted to prevent the locking cover from rotating during use and causing the connection between the plug connector and the socket connector to loosen.

[0016] In a possible implementation, the anti-loosening fastener includes a washer fitted with the cover tube, and a screw threadedly connected to the connecting threaded hole, and a tightening wheel is fixedly connected to the outer end of the screw.

[0017] The above-mentioned structural form makes it easy for the user to turn the tightening wheel to drive the screw to rotate and insert it into the connecting threaded hole, thereby improving installation efficiency.

[0018] In a possible implementation, a plurality of annular grooves are provided on the outer wall of the inner liner pipe and the inner wall of the outer sleeve, and water-blocking rings are installed in the annular grooves.

[0019] With the above-mentioned structural form, the installed water-blocking ring can form multiple water-blocking measures when the cannula is inserted between the inner liner tube and the outer sleeve, thereby preventing the medium from leaking through the insertion gap.

[0020] In a possible implementation, the width of the docking groove is consistent with the width of the docking protrusion, and a chamfer is formed at the front end of the docking protrusion.

[0021] The above structure ensures that after the mating protrusion is inserted into the mating groove, the plug connector and the socket connector cannot rotate relative to each other, while the chamfered edge at the front end of the mating protrusion facilitates the insertion of the mating protrusion.

[0022] In summary, the present invention has the following beneficial technical effects:

[0023] During installation, you only need to insert the cannula into the inner liner and outer sleeve, and then tighten the locking cover. The operation is simple, and the locking cover is threadedly connected to the outer sleeve, which can effectively prevent the cannula from falling out of the slot and ensure the reliability of the connection.

[0024] In the above process, when the cannula is inserted, the docking protrusion and the docking groove can be combined to play a guiding and positioning role, and the valve body will not be offset, which facilitates the installation work. At the same time, the engagement of the docking protrusion and the docking groove can play an anti-torsion role, ensuring the anti-torsion performance of the joint connection.

[0031] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0032] like Figure 1 - Figure 2 As shown, the present embodiment provides a solenoid valve connector docking and fixing device, comprising a solenoid valve body 1, a plug connector 2 connected to a pipe end thereof, the plug connector 2 comprising a plug tube 21, an outer sleeve of the plug tube 21 being provided with an anti-twist ring 22, a socket 3 comprising an inner liner 31 and an outer sleeve 32, the two enclosing a slot for the plug connector 2 to be plugged in, a locking cover 4, which is sleeved on the outside of the plug connector 2 and can be threadedly connected to the outer sleeve 32, wherein the anti-twist ring 22 is provided with a plurality of docking grooves 23 arranged in a circumferential array, and the end of the outer sleeve 32 is fixedly provided with a plurality of docking protrusions 3 matching the docking grooves 23 3. With the above-mentioned structural form, during installation, it is only necessary to insert the cannula 21 into the inner lining tube 31 and the outer sleeve 32, and then tighten the locking cover 4. The operation is simple, and the locking cover 4 is threadedly connected to the outer sleeve 32, which can effectively prevent the cannula 21 from falling out of the slot, ensuring the reliability of the connection. In the above process, when the cannula 21 is inserted, the docking protrusion 33 and the docking groove 23 can be combined to play a guiding and positioning role, and the valve body will not be offset, which facilitates the installation work. At the same time, the engagement of the docking protrusion 33 and the docking groove 23 can play an anti-twisting role, ensuring the firmness of the joint connection.

[0033] like Figure 3 As shown, the locking cover 4 includes a cover tube 41, the rear end of which is fixedly connected to a push ring 42, and the opening diameter of the push ring 42 is smaller than the diameter of the anti-twist ring 22. Through the above structure, when the cover tube 41 is tightened, the push ring 42 will push the anti-twist ring 22, and at the same time cooperate with the tension applied to the outer sleeve 32 by the cover tube 41, so that the plug connector 2 and the socket connector 3 maintain a tendency of relative movement, so that the insert 21 does not have the conditions to slip.

[0034] Among them, an external thread is fixedly provided on the outer wall of the outer sleeve 32, and an internal thread matching the external thread is opened on the inner wall of the cover tube 41. Through the above structural form, the necessary structural basis is provided for the threaded connection between the cover tube 41 and the outer sleeve 32.

[0035] In addition, an elastic gasket 43 is attached to the butt ring 42. The elastic gasket 43 is made of two metal gaskets sandwiched between an elastic rubber gasket and bonded together. Through the above-mentioned structural form, when the butt ring 42 squeezes the elastic gasket 43, it will be subjected to the external thrust of the elastic gasket 43, thereby causing the threads of the cover tube 41 and the outer sleeve 32 to squeeze each other and generate friction, thereby improving the anti-loosening ability of the threaded connection.

[0036] like Figure 3 As shown, a connecting threaded hole 51 is provided on the cover tube 41 and the docking protrusion 33, in which an anti-loosening fastener 5 is threadedly connected. Through the above-mentioned structural form, after the locking cover 4 is tightened, the anti-loosening fastener 5 can be inserted to prevent the locking cover 4 from rotating during use and causing the connection between the plug connector 2 and the socket connector 3 to loosen. The anti-loosening fastener 5 includes a gasket 501 that fits with the cover tube 41, and a screw 502 that is threadedly connected to the connecting threaded hole 51. The outer end of the screw 502 is fixedly connected to a tightening wheel 503. The above-mentioned structural form makes it easy for the user to tighten the tightening wheel 503 to drive the screw 502 to rotate and insert it into the connecting threaded hole 51, thereby improving installation efficiency.

[0037] like Figure 4 As shown, a plurality of annular grooves 341 are provided on the outer wall of the inner liner tube 31 and the inner wall of the outer sleeve 32, and a water-blocking ring 34 is installed in the annular groove 341. Through the above-mentioned structural form, the installed water-blocking ring 34 can form multiple water-blocking measures when the cannula 21 is inserted between the inner liner tube 31 and the outer sleeve 32, thereby preventing the medium from leaking through the plug-in gap.

[0038] like Figure 2 As shown, the width of the docking groove 23 is consistent with the width of the docking protrusion 33, and the front end of the docking protrusion 33 is processed to form a chamfer. Through the above-mentioned structural form, it can be ensured that after the docking protrusion 33 is inserted into the docking groove 23, the plug connector 2 and the socket connector 3 cannot rotate relative to each other, and the chamfer at the front end of the docking protrusion 33 can facilitate the insertion of the docking protrusion 33.

[0039] The use principle and use process of this utility model:

[0040] During installation, it is only necessary to insert the cannula 21 into the inner lining tube 31 and the outer sleeve 32, and then tighten the locking cover 4. The operation is simple, and the locking cover 4 is threadedly connected to the outer sleeve 32, which can effectively prevent the cannula 21 from falling out of the slot, ensuring the reliability of the connection; specifically, when tightening the cover tube 41, the push ring 42 will push the anti-twist ring 22, and at the same time, cooperate with the tension applied to the outer sleeve 32 by the cover tube 41, which can make the plug joint 2 and the socket joint 3 maintain a tendency of relative movement, so that the cannula 21 does not have the conditions to slip.

[0041] In the above process, when the cannula 21 is inserted, the docking protrusion 33 and the docking groove 23 can be combined to play a guiding and positioning role, and the valve body will not be offset, which facilitates the installation work. At the same time, the engagement of the docking protrusion 33 and the docking groove 23 can play an anti-torsion role, ensuring the anti-torsion performance of the joint connection.

[0042] In addition, a plurality of annular grooves 341 are provided on the outer wall of the inner lining tube 31 and the inner wall of the outer sleeve 32, and a water-blocking ring 34 is installed in the annular groove 341. The installed water-blocking ring 34 can form multiple water-blocking measures when the cannula 21 is inserted between the inner lining tube 31 and the outer sleeve 32, thereby preventing the medium from leaking through the plug-in gap.
