Description
Technical field：
The utility model is related to a kind of check-valves, more particularly to a kind of thermal spraying check-valves with multiple filtration net, category
In technical field of hot.
Background technology：
In thermal spray process, oxygen as combustion adjuvant, it is necessary to constantly by oxygen hose inject spray gun, while burning when,
In order to prevent needing to install check-valves additional on tempering, oxygen hose, but during oxygen is from gas tank to spray gun, without filter,
Some impurity in oxygen influence whether the performance of burning, so can typically install filter additional before check-valves, but this
Kind of filter installs complicated, and many links on pipeline, sealing can be caused to decline.Also, it is general used for hot spraying
Check-valves inside in order to carry out sealing, the inner core of check-valves can be installed additional under spring, such normality, and spring heads on inner core always to be made
It keeps sealing, it is necessary to enough pressure could open spring top when oxygen enters check-valves, allows oxygen smoothly to enter spray gun.
If surprisingly causing tempering during burning, in the inner core of now backflash to check-valves, ablation spring repeatedly, soon, this bullet
Spring will it is ablated fall, check-valves just loses the sealing of normality.
Utility model content：
Technical problem to be solved in the utility model is：A kind of thermal spraying check-valves with multiple filtration net is provided, entered
Multiple filtration net is installed, inside uses spring protecting sleeve structure, and filter screen can effectively filter out impurity, and spring protecting sleeve can be anti-at mouthful
Non-return protects valve core inside spring not ablated while fiery.
The utility model is for the technical solution adopted for solving the technical problem：
Set at a kind of thermal spraying check-valves with multiple filtration net, including non-return valve shell, the check-valves housing entry
It is equipped with and holds out against nut, three pressure rings and three filter screens, three pressure rings compresses three filter screens respectively；The check-valves enclosure is set
It is equipped with and described spring, the spring protecting sleeve and spring is provided with spring, spring protecting sleeve and non-return valve core, the spring protecting sleeve
It is arranged on a side of the non-return valve core close to combustion chamber.
Circumferential weld is provided between non-return valve core and the non-return valve shell, facilitates the entrance of oxygen.
Implementation process of the present utility model is as follows：
1. three filter screens are compressed in check-valves porch, respectively with three pressure rings, arrival end is held out against with holding out against nut again, is prevented
Only filter screen comes off；
2. oxygen enters from check-valves inlet region, through three metafiltration nets, and non-return valve core is opened by oxygen pressure top, oxygen from
Both sides circumferential weld enters, through non-return valve core, into combustion chamber；
3. when the combustion chamber tempering of opposite side, tempering enters check-valves, enters from spring protecting sleeve outside, and then withstand only
Valve element is returned, valve element is closed with valve casing inwall, stops that flame enters oxygen channel；
4. in drawing process, spring is all the time in spring protecting sleeve, and such flame is not directly contacted with spring, it is to avoid burn
Erosion.
The utility model is simple in construction, and processing cost is relatively low, with good use value.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is one of operation principle schematic diagram of the present utility model；
Fig. 3 is the two of operation principle schematic diagram of the present utility model.
Embodiment：
The utility model is further explained below in conjunction with the accompanying drawings and explanation：
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of thermal spraying check-valves with multiple filtration net, including non-return valve shell 5, only
The porch for returning valve shell 5 is provided with and holds out against nut 1, three pressure rings 2 and three filter screens 3, and three pressure rings 2 compress three filters respectively
Net 3；It is internally provided with non-return valve shell 1 in spring 4, spring protecting sleeve 7 and non-return valve core 9, spring protecting sleeve 7 and is provided with spring 4,
Spring protecting sleeve 7 and spring 4 are arranged on a side of the non-return valve core 9 close to combustion chamber 6.
Circumferential weld 8 is provided between non-return valve core 9 and non-return valve shell 5, facilitates the entrance of oxygen.
Implementation process of the present utility model is as follows：
1. in check-valves porch, three filter screens 3 are compressed respectively with three pressure rings 2, arrival end is pushed up with holding out against nut 1 again
Tightly, prevent filter screen from coming off；
2. oxygen enters from check-valves inlet region, and through three metafiltration nets 3, non-return valve core 9, oxygen are opened by oxygen pressure top
Enter from both sides circumferential weld 8, through non-return valve core 9, into combustion chamber 6；
3. when the combustion chamber 6 of opposite side is tempered, tempering enters check-valves, enters from the outside of spring protecting sleeve 7, and then withstand
Non-return valve core 9, makes valve element be closed with valve casing inwall, stops that flame enters oxygen channel；
4. in drawing process, spring 4 is all the time in spring protecting sleeve 7, and such flame is not directly contacted with spring 4, it is to avoid
Ablation.
The utility model is simple in construction, and processing cost is relatively low, by installing multiple filtration net, inside in check-valves porch
Using spring protecting sleeve structure, multistorey strainer mesh can effectively filter out impurity, and spring protecting sleeve can be such that spring is not contacted directly with tempering,
It so can effectively lift the service life of spring.
