Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1

In order to solve the above problems, please refer to fig. 1, a sanitary pressure quick-assembly interface is provided, which includes: an industrial pipe 10 and a first nut 20.

Specifically, the first nut 20 is sleeved on the outer side of one end of the industrial pipe 10, the positioning groove 11 is formed in the first nut 20, the first nut 20 is provided with a threaded portion 21 for connecting a workpiece, the stress ring 12 is arranged at the connection position of the industrial pipe 10 and the first nut 20, the stress ring 12 is clamped into the positioning groove 11, and the tetrafluoro gasket 30 is arranged at the end of the industrial pipe 10.

That is, when the workpieces are connected, the connecting structure is formed by the extrusion of the workpieces and the tetrafluoro gasket 30 and the screw extrusion between the workpieces and the first nut 20, since the connected workpieces are coated on the outer side of the industrial pipe 10, the inner wall of the connecting workpiece can extrude the tetrafluoro gasket 30, thereby forming a stable sealing effect, and the tetrafluoro gasket 30 can be more tightly connected with the first nut 20 by the restoring deformation force generated by the extrusion of the connecting workpiece.

Taking the example that the thread portion 21 is disposed on the inner wall of the first nut 20, referring to fig. 2, since the thread is generally disposed at the valve port of the safety valve, the safety valve can be directly connected at this time, the valve port of the safety valve is wrapped around the industrial pipe 10, that is, the structure that the valve port of the safety valve and the orifice of the industrial pipe 10 extrude the tetrafluoro gasket 30 is formed, the deformed tetrafluoro gasket 30 is extruded to seal the gap between the orifice of the industrial pipe 10 and the valve port of the safety valve, so as to form a stable sealing effect, and because the valve port of the safety valve is in threaded connection with the first nut 20, when the valve port of the safety valve and the tetrafluoro gasket 30 extrude, the first nut 20 will be pulled upwards, that is, the first nut 20 will tightly extrude the stress ring 12, forming a positioning function, so as to ensure the connection tightness of the first nut 20 and the valve port of the safety valve.

Referring to fig. 3, for example, the industrial pipe 10 is connected in the same manner by connecting the ball valve and the pressure gauge, except that instead of directly connecting the pressure gauge, the ball valve is connected first, and the pressure gauge is connected with its own valve port.

Referring to fig. 4, taking a ball valve and a quick-screwing socket as an example, in order to further enhance the tightness of the connection position, a cavity is separated between the positioning groove 11 and the stress ring 12, and a second spring 22 is disposed inside the cavity.

Because the stress ring 12 is in a fixed state, the second spring 22 presses the first nut 20 when being compressed, and the second spring 22 presses the first nut 20, so that the connection between the first nut 20 and the threads of the ball valve is tighter, and the problem of loosening the threads is avoided.

Example two

Unlike one embodiment, referring to fig. 5, the threaded portion 21 is disposed on the outer wall of the first nut 20, the first nut 20 is connected with the second nut 40 through the first threaded portion 21, the first nut 20 and the second nut 40 are separated by a cavity, an inner pipe sleeve 50 is disposed in the cavity, one end of the inner pipe sleeve 50 wraps the pipe orifice of the industrial pipe 10, the other end of the inner pipe sleeve 50 is used for wrapping the port for connecting the workpiece, the number of the tetrafluoro washers 30 is two, and the tetrafluoro washers 30 are disposed at the connection position of the inner pipe sleeve 50 and the industrial pipe 10 and the connection position of the inner pipe sleeve 50 and the connecting workpiece, respectively.

That is, in order to ensure that the nozzles with different sizes can still be well connected, the threaded portion 21 is arranged on the outer side, the connection between the second nut 40 and the first nut 20 is used for forming locking, the nozzles and the workpiece are simultaneously locked inside, then the inner sleeve 50 is used for providing the connection of the nozzles, the natural transition between the nozzles with different sizes is ensured, the two groups of tetrafluoro gaskets 30 are matched for providing the sealing connection of the two ends of the inner sleeve 50, and the sealing effect between structures is ensured, and meanwhile, the nozzles with different sizes can be connected and protected.

Taking the quick-screwing socket as an example, the quick-screwing socket and the pipe orifice of the industrial pipe 10 are both clamped into the inner pipe sleeve 50, and then the first nut 20 and the second nut 40 are screwed inwards from two sides of the outer part, so that the quick-screwing socket and the pipe orifice of the industrial pipe 10 can be extruded and can move inwards of the inner pipe sleeve 50, and meanwhile, the inner tetrafluoro gasket 30 is extruded, so that a sealing effect is formed.

Example III

Referring to fig. 6, in addition to the technical scheme in the second embodiment, the following differences are included:

the outside of industry pipe 10 is provided with holding ring 13, and holding ring 13 sets up in the one side that atress ring 12 kept away from second nut 40, is provided with first spring 14 between holding ring 13 and the first nut 20, and the one end of first spring 14 contacts holding ring 13, and the other end of first spring 14 contacts first nut 20.

Namely, the positioning ring 13 limits the position of the first spring 14, the first spring 14 deforms after being extruded, and when the extruding force disappears, the first spring 14 deforms and recovers, and the force generated by the deformation recovery acts on the first nut 20, so that the tightness between the first nut 20 and the screw thread of the second nut 40 after being screwed can be ensured, and the screw thread is prevented from loosening.

Taking the quick screwing socket as an example, the quick screwing socket and the pipe orifice of the industrial pipe 10 are clamped into the inner pipe sleeve 50, then the first nut 20 and the second nut 40 are screwed inwards from two sides of the outer part, the first spring 14 is always in a compressed state before and after the first nut 20 and the second nut 40 are screwed, so that the stability of the position of the first nut 20 can be ensured, the screwing operation is convenient, and after the screwing operation, the extrusion can still be provided, and the tightness between threads is ensured.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
