Abstract
The utility model discloses a kind of safety valve, comprise the air valve on valve seat and valve seat, outlet valve and pressure gauge; Described valve seat is spirally connected with air valve, pressure gauge respectively; It is characterized in that: described outlet valve is provided with a black box with between valve seat, and described black box is threaded with outlet valve and valve seat; Compared with prior art, safety valve of the present utility model, utilizes loose joint nut during attaching, can the installation of accurate quick, is no longer limited to circumscribed interface position direction; When situation appears in outlet valve or needs inspection changes time, without the need to closed safe valve main switch, outlet valve and valve seat in succession inside have movable sealer, only need turn on outlet valve and namely allow jointing be in closed state.Reinstall outlet valve after to be replaced, black box circulates, and outlet valve can be resumed work.Safety valve of the present utility model is convenient when installing and change valve body.
Description
Technical field
The utility model relates to a kind of safety valve.
Background technique
Common safety valve is when attaching, and we enter to connect by twisting valve body to be spirally connected, and often occur the problems such as some valve body position inaccuracy, distortions when tightened, cause inconvenience during installation.And valve body go wrong need change valve body time we need valve body main switch, just can change, then change after reopen safety valve main switch again, cause unnecessary trouble.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of safety valve, and it can ensure in attaching with convenient during replacing valve body.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of safety valve, comprises the air valve on valve seat and valve seat, outlet valve and pressure gauge; Described valve seat is spirally connected with air valve, pressure gauge respectively; It is characterized in that: described outlet valve is provided with a black box with between valve seat, and black box is flexibly connected with outlet valve and valve seat.
Described black box is threaded with outlet valve and valve seat.
Described black box comprises spring, connecting base, plug and seal ring; Described plug comprises plug head and bar; Described bar shaped flat is like cuboid, and both sides are provided with spacing fixture block; Described seal ring is located in the groove of plug head; Described plug is through connecting base and spring, and plug is stuck in connecting base mouth by seal ring, and spring housing is on bar, and spring is stuck between fixture block and connecting base by bar both sides fixture block.
The beneficial effects of the utility model:
Compared with prior art, when situation appears in outlet valve or needs inspection changes time, without the need to closed safe valve main switch, outlet valve and valve seat in succession inside have movable sealer, only need turn on outlet valve and namely allow jointing be in closed state; Reinstall outlet valve after to be replaced, black box circulates, and outlet valve can be resumed work.
Accompanying drawing explanation
Fig. 1 is the utility model safety valve schematic diagram
Fig. 2 is seal component architecture schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, the utility model provides a kind of safety valve, comprises valve seat 13 and air valve 11, outlet valve 10 and the pressure gauge 15 on valve seat; Described valve seat 13 is spirally connected with air valve 11, pressure gauge 15 respectively; Described air valve 11 adopts traveling nut joint 12 with valve seat 13, and described outlet valve 10 is provided with a black box 14 with between valve seat 13, and described black box 14 is threaded with outlet valve 10 and valve seat 13.
Refer to Fig. 2, described black box comprises spring 4, connecting base 1, plug 2, seal ring 3 and seal ring 5; Described plug 2 comprises plug 2 head and bar 9; Described bar 9 shaped flat is like cuboid; Described seal ring 3 is located in plug 2 head recess 7; Described plug 2 through connecting base 1 and spring 4, plug 2 head recess 7 inner seal ring 3 and connecting base mouth 8 OK a karaoke club, and bar 9 is through spring 4, bar 9 both sides are provided with spacing fixture block 6 by spring clip 4 between fixture block 6 and connecting base 1; In time having power extruding bar 9, bar fixture block 6 can promote spring 4, makes spring-compressed, and plug 2 projects upwards together with seal ring 3, leaves connecting base mouth 8, and black box sealing state is removed; In time not having power to extrude bar 9, under the effect of spring 4, promote bar fixture block 6 and allow bar 9 bounce back, bar plug 2 is seal ring 3 in succession, due to wider than connecting base mouth 8, namely block connecting base outlet 8, makes to be in sealing state.
On air valve 11, traveling nut joint 12 and valve seat 13 are spirally connected, and utilize traveling nut joint 12 during attaching, can the installation of accurate quick, are no longer limited to circumscribed interface position direction.
Below working principle of the present utility model is made an explanation:
When installing outlet valve, along with nut is constantly tightened, outlet valve 10 port in succession can give the power that bar 9 one promotes, this power makes bar constantly move forward, and when bar fixture block 6 encounters spring, thrust makes spring 4 compress, plug 2 in succession seal ring 3 leaves connecting base outlet, when after outlet valve installation, interface reaching inwards seal ring 5, connecting base outlet 8 is in circulation status completely; When needing repairing or change outlet valve, outlet valve of back-outing, along with outlet valve is constantly back-outed, the thrust suffered by bar 9 reduces gradually, under the reaction force of spring 4, promotes bar fixture block 6 and bar is bounced back.Namely allow plug 2 in succession plug groove seal ring 3 gradually toward retraction, until arrive at connecting base mouth 8, cannot stretch again, make connecting base mouth be in closed state; Without the need to closing outlet valve main switch, replacing or the maintenance of valve can be exhausted;
Above to a kind of safety valve that the utility model embodiment provides, be described in detail, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment is just for helping to understand the technological scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
