Embodiment
Below in conjunction with embodiment, further set forth the present invention:
A kind of selectable double-gas intake device of the present invention, this device comprises two suction port a and b, one of them suction port a (b) is fixed with an activity type of tamper evidence, this type of tamper evidence is sealed one of them suction port a (b), under certain gas pressure, type of tamper evidence moves to another suction port b (a) and locates to make its sealing.
As shown in Figure 1, this type of tamper evidence is a steel ball 2, is fixed on suction port a place by magnet 1, and suction port a is sealed.At the input low-BTU gas, during as liquid gas, suction pressure makes steel ball 2 break away from magnet 1 and move to suction port b place with its sealing (shown in Fig. 1-B) greater than the magnetic force of magnet.
As shown in Figure 2, this type of tamper evidence is a slide block 3, slide block 3 is in suction port a place, the two ends of this slide block are adsorbed on chamber inner wall with magnet 1 respectively, its top seals suction port a (as Fig. 2-A), its length is identical with suction port place chamber height, when the input low-BTU gas, suction pressure can promote 3 motions of this slide block, cause it to move to suction port b place and with its sealing (as Fig. 2-B).
As shown in Figure 3, this type of tamper evidence is a baffle structure, it comprises that one is fixed on the lever 5 between two suction ports (a, b), and at lever 5 two ends corresponding suction ports (a, b) locate to fix respectively a catch 4, one of them of catch 4 is subjected to the stressed area of contact of the area of plane of stream pressure greater than another catch, and between lever end that the small area of contact catch is housed and chamber inner wall, fix a spring 6, spring 6 makes suction port a of catch sealing of small area of contact.If the input low-BTU gas, during as liquid gas, suction pressure acts on the long-pending catch of large contact surface, utilizes lever principle pulling spring, makes the long-pending catch sealing of large contact surface suction port b (as Fig. 3-B).
As shown in Figure 4, baffle structure of the present invention comprises a shifting board 7, shifting board 7 places in the chamber and be provided with air hole on this shifting board, and be connected a catch 4 respectively with the b place at shifting board 7 corresponding suction port a, and fix a spring 6 at the intermediate portion and the chamber inner wall that connect catch, one of them catch 4 places the outside of corresponding suction port a to make sealing, and another catch 4 places inboard a distance of its corresponding suction port b.If input low-BTU gas, during as liquid gas, on the suction pressure effect shifting board 7, promote shifting board 7 and pressure spring 6 and make catch 4 motions, the catch 4 that wherein seals suction port a makes it open away from suction port a, and another catch 4 is sealed into gas port b (as Fig. 4-B).
As shown in Figure 5, baffle structure of the present invention comprises a pull bar 8, and an end of pull bar 8 passes one of them suction port b and fixes a washer, makes suction port b sealing, and the other end of pull bar 8 is fixed an epithelium 9, and epithelium is fixed on chamber inner wall; Establish a spring 6 between pull bar 8 and suction port b inboard; Epithelium 9 is established a projection 10 at corresponding another suction port a place, and projection 10 makes another suction port a sealing.If input low-BTU gas, during as liquid gas, suction pressure acts on the epithelium 9, promotes epithelium 9 and pressure spring 6 and makes pull bar 8 motions, and the catch that drives sealing suction port a makes it open away from suction port a, and makes projection on the epithelium 9 be sealed into gas port b (as Fig. 5-B).
Working principle of the present invention is: when air inlet is a high heat value gas, during as rock gas, suction pressure is little can not to change the original state of type of tamper evidence, can only be from open suction port air inlet (as Fig. 1-A, 2-A, 3-A, 4-A, 5-A); When air inlet is a lower calorific value, during as liquid gas, suction pressure is greatly that above-mentioned certain air pressure can make the type of tamper evidence motion, it is moved to another suction port and seal this suction port (as Fig. 1-B, 2-B, 3-B, 4-B, 5-B).By above technology, selectable double-gas intake device of the present invention can be judged the gas of input automatically and select corresponding suction port automatically.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
