Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of steam line pipe cap, can prevent the impact that unexpected high pressure causes for pipe cap, has protected pipe cap.
For achieving the above object, the utility model provides following technological scheme: a kind of steam line pipe cap, comprise outer wall, inwall and inner chamber, described inner chamber is provided with between dividing plate and described dividing plate and inwall and is formed with sealed cavity, on described dividing plate, offer through hole and described dividing plate is provided with air pipe along the direction of axis line of through hole, described air pipe is positioned at sealed cavity, described air pipe is provided with elastic component and baffle plate with respect to the other end of through hole, described elastic component one end is fixedly connected with the pipe bottom of air pipe and the other end is fixedly connected with baffle plate, described dividing plate is provided with abutting part in through hole, described baffle plate is inconsistent with respect to the other end being connected with elastic component and abutting part, on tube wall in described air pipe and sealed cavity, be provided with air hole, described outer wall is provided with salable or opens the operation unit of this air outlet in sealed cavity one side is provided with air outlet and described air outlet.
By adopting technique scheme; if pressure raises suddenly in pipeline; if the pressure raising is higher than the compression potential energy of elastic component; baffle plate now just can be backed down; in the air hole of steam from air pipe tube wall, enter sealed cavity, then dragged air outlet that gas is discharged, carry out pressure release; protect pipe cap with this, pipe cap can not damaged because of unexpected high pressure.
The utility model is further set to: described air pipe is also provided with regulator plate, described elastic component is fixedly connected with regulator plate in the pipe bottom of air pipe one side, the opposite side of described regulator plate is provided with push rod and described push rod is provided with adjusting portion with respect to the other end being connected with regulator plate, and described adjusting portion can be controlled push rod and move along the direction of axis line of through hole.
By adopting technique scheme, thus regulating and controlling portion just can regulating and controlling plate motion control the elastic potential energy of elastic component, carry out the pressure bearing limit of this pipe cap of regulating and controlling with this.
The utility model is further set to: described push rod and adjustable side one side are provided with outside thread, described adjusting portion setting is provided with internal thread, described push rod is threaded with adjusting portion, and described adjusting portion axis is fixedly installed on outer wall and can rotates in a circumferential direction along the shaft axis of push rod.
By adopting technique scheme, rotate adjusting portion and drive push rod to move up and down, and the Placement of screw thread is without using other axial restraint, simple and reliable for structure, easy to operate.
Brief description of the drawings
Fig. 1 is the utility model steam line pipe cap embodiment's structural representation.
Embodiment
With reference to Fig. 1, the utility model steam line is described further by pipe cap embodiment.
A kind of steam line pipe cap, comprise outer wall 2, inwall 1 and inner chamber 11, described inner chamber 11 is provided with between dividing plate 3 and described dividing plate 3 and inwall 1 and is formed with sealed cavity 4, on described dividing plate 3, offer through hole 32 and described dividing plate 3 is provided with air pipe 5 along the direction of axis line of through hole 32, described air pipe 5 is positioned at sealed cavity 4, described air pipe 5 is provided with elastic component 10 and baffle plate 52 with respect to the other end of through hole 32, described elastic component 10 one end are fixedly connected with the pipe bottom of air pipe 5 and the other end is fixedly connected with baffle plate 52, described dividing plate 3 is provided with abutting part 31 in through hole 32 places, described baffle plate 52 is inconsistent with respect to the other end being connected with elastic component 10 and abutting part 31, on tube wall in described air pipe 5 and sealed cavity 4, be provided with air hole 51, described outer wall 2 is provided with salable or opens the operation unit 6 of this air outlet in sealed cavity 4 one sides are provided with air outlet and described air outlet.
