Description
Technical field
The utility model is related to fire-fighting equipment field, more particularly, to a kind of level pressure dress suitable for gas extinguishing system
Put.
Background technology
Be loaded on level pressure pressing diaphragm in level pressure release aperture by safe pressure ring in the constant pressure arrangement used in gas extinguishing system, and
The upper surface of safe pressure ring belongs to face and contacts with the end face of M16 joints, safe pressure ring and M16 joints end face process it is smooth
In the case that degree is not high, in the case that localized contact is not in place, it is impossible to by the pressure conduction of M16 joints to level pressure diaphragm, also,
Contacted using smooth face between safe pressure ring and M16 joints, there is also the problem for producing Relative sliding, cause safe pressure
Stability and less reliable that ring is installed.
Utility model content
The purpose of this utility model is to provide a kind of constant pressure arrangement, and it can allow presses the joint being located on safe pressure ring and pacify
The stability of installation, reliability are higher between total head ring.
In order to solve the above technical problems, implementation method of the present utility model provides a kind of constant pressure arrangement, it includes：Four-way
Main component, it include the upper installing port of coaxial arrangement and lower installing port and be arranged on the left of four-way main component left installing port,
The right installing port on the right side of four-way main component is arranged in, upper installing port, lower installing port, left installing port, right installing port are equipped with interior spiral shell
Line structure, the left and right installing port of four-way main component is provided with M24 joints, and seal washer is provided with left and right installing port, under
Installing port is provided with seal washer, and upper installing port is provided with M16 joints, and M16 joint pressures set to be provided with and are arranged in from top to bottom
The safe pressure ring of installing port, level pressure diaphragm, seal washer, the lower surface of M16 joints are provided with that some teeth are convex, and safe pressure ring is set
There is the recess with the convex cooperation of tooth.
Compared with prior art, in the constant pressure arrangement that the utility model is provided, the tooth set by M16 joints lower surface is convex
Recess with safe pressure ring cooperates, and safe pressure ring firmly is fixed on into joint end face lower section, it is to avoid safe pressure ring occurs
Sliding.
Further, the convex section of tooth is triangle.
Brief description of the drawings
Fig. 1 is constant pressure arrangement structural representation；
Fig. 2 is detail drawing at M in Fig. 1.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face in conjunction with specific embodiments, is expanded on further the utility model.
Implementation method of the present utility model provides constant pressure arrangement, and referring to Fig. 1, it includes four-way main component 2, four-way master
Body part 1 includes the upper installing port and lower installing port of coaxial arrangement and the left installing port, the arrangement that are arranged on the left of four-way main component
Right installing port on the right side of four-way main component, upper and lower installing port, left and right installing port are equipped with female thread structure, four-way main component
Left and right installing port is provided with M24 joints 1, is provided with seal washer 7 in left and right installing port, and lower installing port be also provided with it is close
Seal washer 8, upper installing port is provided with M16 joints 3, and M16 joint pressures set the safety for being provided with and being arranged in installing port from top to bottom
Pressure ring 4, level pressure diaphragm 5, seal washer 6.
Referring to Fig. 2, the lower surface of M16 joints is provided with some teeth convex 9, and safe pressure ring is provided with recessed with the convex cooperation of tooth
Portion.The tooth convex 9 of such as triangle, after the triangular-shaped recess of lance tooth convex press-in safe pressure ring, safe pressure ring then cannot be again
With respect to the displacement that M16 joints carry out any direction.
The aerodynamic pressure scope of the constant pressure arrangement is 3.4 ± 0.17Mpa.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
