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, by magnet 1, is fixed on suction port a place, and suction port a is sealed.At input low-BTU gas, during as liquid gas, suction pressure is greater than the magnetic force of magnet, makes steel ball 2 depart from magnet 1 and move to suction port b place and is sealed (as shown in Fig. 1-B).
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 is by suction port a sealing (as Fig. 2-A), and its length is identical with suction port place chamber height, when input low-BTU gas, suction pressure can promote this slide block 3 motions, causes it to move to suction port b place and is sealed (as Fig. 2-B).
As shown in Figure 3, this type of tamper evidence is baffle structure, it comprises that one is fixed on the lever 5 between two suction ports (a, b), and locate to fix respectively a catch 4 at the lever corresponding suction ports in 5 two ends (a, b), one of them of catch 4 is subject to the area of plane of stream pressure to be greater than the stressed area of contact of another catch, and fix a spring 6 being equipped with between the lever end of small area of contact catch and chamber inner wall, spring 6 makes a suction port a of catch sealing of small area of contact.If input low-BTU gas, during as liquid gas, suction pressure acts on the long-pending catch of large contact surface, utilizes lever principle to pull 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 is placed in chamber and is provided with air hole on this shifting board, and be connected respectively a catch 4 at the corresponding suction port a of shifting board 7 with b place, and fix a spring 6 at the intermediate portion and the chamber inner wall that connect catch, the outside that one of them catch 4 is placed in corresponding suction port a makes sealing, and another catch 4 is placed in a distance, inner side of its corresponding suction port b.If input low-BTU gas, during as liquid gas, on suction pressure effect shifting board 7, promote shifting board 7 Compress 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 one end of pull bar 8 is through one of them suction port b and fix 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; Between pull bar 8 and suction port b inner side, establish a spring 6; 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 epithelium 9, promotes epithelium 9 Compress Spring 6 and makes pull bar 8 motions, and drive the catch of sealing suction port a to make it open away from suction port a, and make the projection on epithelium 9 be sealed into gas port b (as Fig. 5-B).
Working principle of the present invention is: when air inlet is high heat value gas, during as rock gas, suction pressure is little can not 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 lower calorific value, during as liquid gas, suction pressure is greatly that above-mentioned certain air pressure can make type of tamper evidence motion, is moved to another suction port and seals 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 automatic decision input gas and automatically select corresponding suction port.
But above-mentioned embodiment is exemplary, be to be this patent to be comprised to the restriction of 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 do be anyly equal to change or modify, all fall into the scope that this patent comprises.
