Abstract
The utility model discloses a kind of new type natural air filter, comprise outer valve (1), valve gap (2), air inlet pipe (3) and escape pipe (4), inner valve body (11) is provided with in outer valve (1), air inlet pipe (3) is communicated with inner valve body (11) through outer valve (1), escape pipe (4) is communicated with outer valve (1), the inwall of inner valve body (11) is provided with spacing ring (5), is provided with filter core (6) in inner valve body (11); The bottom of valve gap (2) is provided with filter core positioner (7).The utility model can prevent the impurity on filter core from entering escape pipe, available protecting downstream voltage adjusting device.
Description
Technical field
The utility model relates to a kind of filter, and particularly a kind of new type natural air filter, belongs to natural gas facility field.
Background technology
Along with China's environmental pollution is more and more serious, increasing people starts choice for use clean energy resource, natural gas is widely used as clean energy resource, need after natural gas is extracted to use filter to filter, natural gas after filtration flows to user again and uses, natural gas filter needs manually to carry out to clear up or more renew cartridge in use for some time, when changing, the impurity of cartridge surface and dust can fall into the bottom of valve body, because valve space is narrow, staff is difficult to the impurity of body base to clean out, so this part impurity will enter downstream gas pipeline along with natural gas, and then enter the equipment such as pressure regulator valve, be easy to the blocking and the damage that cause downstream voltage adjusting device, the cleaning work of voltage adjusting device extremely bothers, change parts price very high, all there is this shortcoming in the right filter of weather of the prior art, urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is, provides a kind of new type natural air filter, and it can prevent the dust on filter core and impurity from entering escape pipe, available protecting downstream voltage adjusting device.
The technical solution of the utility model: a kind of new type natural air filter, comprise outer valve, valve gap, air inlet pipe and escape pipe, inner valve body is provided with in outer valve, air inlet pipe is communicated with inner valve body through outer valve, escape pipe is communicated with outer valve, the inwall of inner valve body is provided with spacing ring, is provided with filter core in inner valve body; The bottom of valve gap is provided with filter core positioner.By arranging inner valve body, even if the impurity when more renew cartridge on filter core drops also can fall in air inlet pipe, and not worrying that impurity enters escape pipe, can available protecting downstream natural gas facility.
In aforesaid this new type natural air filter, described filter core positioner is a cylindrical metal bar, and the diameter of cylindrical metal bar is less than the diameter of filter core.
In aforesaid this new type natural air filter, described filter core positioner comprises guide rod, spring and pressing plate, and one end of guide rod is fixedly connected with the bottom of valve gap, and the other end is provided with the pressing plate be slidably connected with it, and spring housing is connected on guide rod.By arranging pressing plate and spring, by the elastic force of spring can by pressing plate tightly be pressed in inner valve body, prevent filter core from misplacing.
In aforesaid this new type natural air filter, described inner valve body is arranged on the center in outer valve, and inner valve body and outer valve are cylindrical-shaped structure.
In aforesaid this new type natural air filter, air inlet pipe and escape pipe are equipped with pressure interface.Pressure texture is set the equipment such as regulator or air gauge can be installed, contribute to the safety monitoring valve body and gas pipeline.
Compared with prior art, the structure that the utility model is separated by adopting interior outer valve, air inlet pipe is communicated with inner valve body, filter core is arranged in inner valve body, even if filter core drops when more renew cartridge like this, impurity also can only fall in inner valve body, drop back into tracheal strips, and the gap that can not fall between outer valve and inner valve body, by adopting the valve body of this structure, not only effectively can prevent impurity from entering the circulation area that escape pipe can also ensure gas, there is the advantage that structure is simple and easy to maintenance.Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
Being labeled as in accompanying drawing: 1-outer valve, 2-valve gap, 3-air inlet pipe, 4-escape pipe, 5-spacing ring, 6-filter core, 7-filter core positioner, 8-guide rod, 9-spring, 10-pressing plate, 11-inner valve body, 12-pressure interface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the art of this patent is further described.
Embodiment 1 of the present utility model: as shown in Figure 1, a kind of new type natural air filter, comprise outer valve 1, valve gap 2, air inlet pipe 3 and escape pipe 4, inner valve body 11 is provided with in outer valve 1, air inlet pipe 3 is communicated with inner valve body 11 through outer valve 1, and escape pipe 4 is communicated with outer valve 1, and the inwall of inner valve body 11 is provided with spacing ring 5, be provided with filter core 6 in inner valve body 11, one end that filter core 6 opening is larger is installed down; The bottom of valve gap 2 is provided with filter core positioner 7.
Described filter core positioner 7 is a cylindrical metal bar, and the diameter of cylindrical metal bar is less than the diameter of filter core 6.Described inner valve body 11 is arranged on the center in outer valve 1, and inner valve body 11 and outer valve 1 are cylindrical-shaped structure.Air inlet pipe 3 and escape pipe 4 are equipped with pressure interface 12.
Embodiment 2 of the present utility model: as shown in Figure 2, a kind of new type natural air filter, comprise outer valve 1, valve gap 2, air inlet pipe 3 and escape pipe 4, inner valve body 11 is provided with in outer valve 1, air inlet pipe 3 is communicated with inner valve body 11 through outer valve 1, and escape pipe 4 is communicated with outer valve 1, and the inwall of inner valve body 11 is provided with spacing ring 5, be provided with filter core 6 in inner valve body 11, one end that filter core 6 opening is larger is installed down; The bottom of valve gap 2 is provided with filter core positioner 7.
Described filter core positioner 7 comprises guide rod 8, spring 9 and pressing plate 10, and one end of guide rod 8 is fixedly connected with the bottom of valve gap 2, and the other end is provided with the pressing plate 10 be slidably connected with it, and spring 9 is socketed on guide rod 8.Described inner valve body 11 is arranged on the center in outer valve 1, and inner valve body 11 and outer valve 1 are cylindrical-shaped structure.Air inlet pipe 3 and escape pipe 4 are equipped with pressure interface 12.
