Description
Technical field:
The utility model relates to gas unidirectional valve field, particularly a kind of one-way valve that is used for board-like pressurized gas dry decontamination device.
Background technique:
What install in the lower plate of existing board-like pressurized gas dry decontamination device is the embedded regeneration gas one-way valve of monomer, by the spiral plug, spring, seal ring and steel ball are formed, in assembly process, the steel ball center will with spring center on a center line, lower plate need be holded up and can be assembled success, has increased in the device maintenance process difficulty of changing this one-way valve greatly.
The model utility content:
The purpose of this utility model is to provide a kind of regeneration gas one-way valve of overall structure mode, and no matter which kind of mode is lower plate be is assembled, all can be convenient for assembly, solved the difficult problem in the assembling maintenance, and improved reliability and work efficiency.
The purpose of this utility model is achieved by the following technical programs:
The regeneration gas one-way valve that is used for board-like pressurized gas dry decontamination device, the valve body and the valve seat that comprise screw-thread fit, valve seat is provided with the pore that axial and circumferential connect, valve body is provided with air cavity and the pore that is communicated with the valve seat pore, be provided with spool in the described air cavity, it is characterized in that: described spool is provided with inner chamber apart from the valve seat far-end, one spring is set in the inner chamber vertically, spool outer wall and valve interior wall Spielpassung, the nearly valve seat end of spool is provided with pore, described valve seat the inner is provided with seal groove, is inserted in seal ring in the seal groove, and valve seat is inner to be sealed by the seal ring compressional deformation with valve interior wall.
The outer end of described valve body is a conical surface 10, and this conical surface cooperates with mounting hole in the board-like pressurized gas dry decontamination device lower plate and forms the nonflexible line sealing.
The nearly valve seat end of described spool is provided with six pores with center line angle at 45.
Pore is as gas-entered passageway on valve seat, and the pore on the valve body is during as outlet passageway, and high-pressure gas pressure impels the spool pressure spring, the pore on the gas flow valve body.Pore on valve body is as gas-entered passageway, and when pore was as outlet passageway on the valve seat, pressurized gas entered valve inner, and gas pressure is depressed on the spool inclined-plane, impels spool and seal ring to closely cooperate, and air-flow path is shut, and reaches the effect of unidirectional ventilation.
The utility model is to be connected with lower plate in the board-like pressurized gas dry decontamination device with the regeneration gas one-way valve of overall structure mode, no matter which kind of mode is lower plate be is assembled, all can be convenient for assembly, solved the difficult problem in the existing regeneration gas one-way valve assembling maintenance, improved reliability and work efficiency.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the device schematic representation of lower plate in the utility model and the board-like pressurized gas dry decontamination device.
Among the figure: 1. valve seat, 2. valve body, 3. seal ring, 4. spool, 5. spring, 6. pore, 7. pore, 8. pore, 9. air cavity, 10. conical surface, 11. inner chambers, 12. spool inclined-planes, 13. screw threads, 14. adsorption towers, 15. adsorption towers, 16. regeneration gas one-way valves, 17. regeneration gas passages, 18. crest lines.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, valve seat 1 is provided with the pore 6 that axial and circumferential connect, valve body 2 is provided with air cavity 9 and the pore 8 that is communicated with valve seat pore 6, be provided with spool 4 in the air cavity 9, spool 4 is provided with inner chamber 11 apart from valve seat 1 left end, and spring 5 is inserted in the inner chamber 11 vertically, in the air cavity 9 of the valve body 2 of packing into together then, this moment spool 4 outer walls and valve body 2 inwall Spielpassung, spool 4 nearly valve seat 1 ends are provided with six pores 7 with center line angle at 45.Be inserted in seal ring 3 on the seal groove of valve seat 1 the inner, valve seat 1 is threaded with valve body 2 then, and the seal ring 3 of this moment because of the inwall with check valve body closely cooperates deformation takes place, being stuck in the seal groove tightly, and be unlikely to be washed out by high pressure draught.In conjunction with shown in Figure 2, this regeneration gas one-way valve 16 is installed in the inside groove of regeneration gas passage 17 1 sides of adsorption tower 14,15, the outer end of valve body 2 is a conical surface 10, valve body 2 outer end conical surfaces 10 cooperate with mounting hole in the board-like pressurized gas dry decontamination device lower plate, and form the nonflexible lines sealing with accurate applying of crest line 18 of lower plate, when screwing in lower plate, whole one-way valve is threaded with lower plate by the screw thread on the valve seat 1 13, no matter which kind of mode is lower plate be is assembled, all can be convenient for assembly, solve the difficult problem in the assembling maintenance, improved reliability and work efficiency.
When pressurized gas by valve seat 1 on pore 6 when entering, gas pressure impels spool 4 pressure springs 5 to be moved to the left, pore 7 is opened on the spool, gas flows out by pore 7 pore 8 to the valve body 2.When pressurized gas by valve body 2 on pore 8 when entering, pressurized gas enter valve inner, gas pressure is depressed on the spool inclined-plane 12, impels spool 4 and seal ring 3 to closely cooperate, air-flow path is shut, and reaches the effect of unidirectional ventilation.
The foregoing description only is a better embodiment of the present utility model; describe technical conceive of the present utility model and essential implementation in detail; be not to be that protection domain of the present utility model is limited; all any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the present utility model.
