Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the specific embodiments in the specification. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, fig. 1 is a schematic view of a combination structure of an embodiment of a timing transmission device of a gas safety valve according to the present invention; fig. 2 is an exploded view of an embodiment of the timing transmission device of the gas safety valve of the present invention. The timing transmission device of the gas safety valve comprises: the timer device comprises a fixed plate 10 fixedly connected with a timer bracket 60, a first interference part 11 and a second interference part 12 arranged on the lower surface of the fixed plate 10, a transmission member 20 arranged below the fixed plate 10, a clamping member 30 and a bearing plate 40 bearing the transmission member 20 and the clamping member 30. A timer (not shown) is installed in the timer holder 60, and the timer is a mechanical timer, and when the user rotates the timer to rotate the timer around the shaft 601 of the timer holder 60 for timing, the timer slowly rotates around the shaft 601 of the timer holder 60 in the opposite direction, and stops rotating when the timing time is over. During the operation of the timer, the fixing plate 10 fixedly connected with the timer through the shaft 601 can also rotate along with the timer.
Therefore, the first interference portion 11 and the second interference portion 12 may be disposed at suitable positions of the fixing plate 10, so that when the timing of the timer is started, the first interference portion 11 may be located right above the driving member 20 and press the driving member 20 to move downward, and then the driving member 20 may press the downstream valve 50 of the gas safety valve disposed below the driving member 20, so that the valve of the downstream valve 50 of the gas safety valve may be opened. In addition, during the downward movement of the transmission member 20, it will be held by one end of the holding member 30, and at this time, the valve of the forward pressure valve 50 is always in an open state. Since the transmission member 20 is held by one end of the holding member 30, the transmission member 20 is out of contact with the first interference part 11 during the opening of the valve of the forward pressure valve 50, and thus the acting force pressing the valve of the forward pressure valve 50 is not transmitted to the fixed plate 10. When the timer moves to the original position and stops rotating, the second interference part 12 will poke the other end of the retaining member 30, so that the retaining member 30 releases the transmission member 20, and therefore the transmission member 20 moves upwards under the elastic recovery action of the pressure relief valve 50, and the valve of the pressure relief valve 50 of the gas safety valve can be closed.
The timing transmission device of the gas safety valve of the invention separates the first interference part 11 and the second interference part 12 of the fixing plate 10 from the transmission part 20 and the clamping part 30 on the bearing plate 30, and the transmission part 20 does not need to be always abutted against the first interference part 11 in the running process of the timer. Therefore, the acting force of the transmission piece 20 on the timer is avoided, and the service life of the timer is prolonged.
Further, a through hole 101 is formed at a middle position of the fixing plate 10, and the shaft 601 of the timer support 60 passes through the through hole 101 and is fixedly connected to the fixing plate 10. And the lower surface of the fixing plate 10 protrudes to form a convex hull, i.e. a first interference part 11; the lower surface of the fixing plate 10 also extends outward to form a pick, i.e., a second interference portion 12. The positions of the first interference portion 11 and the second interference portion 12 on the fixing plate 10 are not limited herein. When the timer is timed at the positions of the first interference part 11 and the second interference part, the first interference part 11 extrudes the transmission part 20, and when the timer rotates to the original position, the second interference part 12 shifts the clamping part 30, which are all within the protection scope of the patent.
Further, a clamping part 21 capable of clamping with the clamping part 30 is arranged on the side wall of the transmission part 20; the carrier plate 40 protrudes to form an accommodating portion 41 for accommodating the transmission member 20, the accommodating portion 41 is provided with an accommodating hole 411 adapted to the transmission member 20, and the accommodating hole 411 vertically penetrates through the accommodating portion 41 and the carrier plate 40. The outer surface of the receiving portion 41 is partially recessed toward the inner surface to form a receiving groove 412 communicating with the receiving hole 411, and the receiving groove 412 is used for receiving the retaining member 30 and can be retained with the retaining portion 21 of the transmission member 20 received in the receiving hole 411.
Furthermore, the driving member 20 may be a cylindrical body, and the sidewall of the driving member 20 is recessed or protruded outward to form the retaining portion 21, i.e. the retaining portion 21 is a groove annularly disposed on the sidewall of the driving member 20. The transmission member 20 may be stepped, and the stepped surface thereof forms the engaging portion 21.
Referring to fig. 3, fig. 3 is a schematic view of an assembly structure of the carrier plate and the retaining member in the timing transmission device of the gas safety valve of the present invention. The holding member 30 includes a shifting rod 31, a holding rod 33 and a connecting rod 32 connecting the shifting rod 31 and the holding rod 33, the shifting rod 31 and the second interference portion 12 form an interference contact, and the holding rod 33 is accommodated in the accommodating groove 412. Specifically, the clamping rod 33 and the connecting rod 32 are integrally bent, a mounting hole 321 is formed at the joint of the connecting rod 32 and the clamping rod 33, and the poke rod 31 is perpendicular to the connecting rod 32. Correspondingly, the supporting plate 40 is further provided with a mounting portion 42 for mounting the retaining member, and a pillar is disposed on the top of the mounting portion 42. When the retainer is mounted on the fixing plate 10, the support post may pass through the mounting hole 321, and the retainer bar 33 is received in the receiving groove 412. Furthermore, an elastic pushing-against piece 70 is further disposed on the bearing plate 40, one end of the elastic pushing-against piece 70 is fixed on the bearing plate 40, and the other end is pushed against the poke rod 31. The elastic pushing-against part 70 interferes with the poke rod 31, and the elastic force of the elastic pushing-against part 70 pushes the clamping part 30 to rotate around the support as a pivot. For example, if the tap lever 31 is rotated in the direction of the arrow a catch, the catch lever 33 will move in the direction of the arrow b. In the embodiment of the present invention, the elastic pushing-against member may be a torsion spring or other springs, and all the elastic pushing-against members 70 that can make the pulling rod 31 always have a tendency to rotate along the arrow a direction are within the protection scope of the present invention.
Further, the support plate 40 is further provided with a protrusion 43 for supporting one end of the connecting rod 32 connected to the tap lever 31, and the height of the protrusion 43 is substantially equal to the height of the mounting portion 42. The protrusion 43 may serve not only to support the connecting rod 32 but also to guide the movement of the connecting rod 32.
The timing transmission device can be used in a gas safety valve, and can be used in other devices. The specific description is given only by taking the application in the gas safety valve as an example, and other application examples can be referred to for implementation.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of the housing of the gas safety valve of the present invention. The gas safety valve includes a housing 200, and the housing 200 includes an upper chamber 201, a lower chamber, an airtight membrane 204 separating the upper chamber 201 and the lower chamber, and an inlet duct 300 and an outlet duct 400 disposed on the housing 200. Meanwhile, the lower chamber is divided into a first lower chamber 202 and a second lower chamber 203 by a partition plate 205, and a through hole 206 communicating the first lower chamber 202 and the second lower chamber 203 is formed in the partition plate 205. The inlet duct 300 communicates with the first lower chamber 202, and the outlet duct 400 communicates with the second lower chamber 203 through the small hole 401. Referring to fig. 1, the timing transmission device and the timer holder 60 are further disposed in the upper chamber 201, and the downstream valve 50 is disposed in the lower chamber. The downstream valve 50 has a valve plate 51, a straight rod 52 and an elastic member 53 disposed below the valve plate 51. The straight rod 52 passes through the through hole 205 and extends to the airtight membrane 204, and the valve plate 51 is disposed in the first lower accommodating chamber 202 and tightly attached to the surface of the partition plate 205, so that the communication between the first lower accommodating chamber 202 and the second lower accommodating chamber 203 is cut off, and the gas in the gas inlet pipe 300 cannot be communicated with the gas outlet pipe 400 through the through hole 206. The specific structure of the timing transmission device in the gas safety valve can refer to the above description and refer to fig. 1 to 3, and the detailed description is omitted here. The straight rod 52 of the pressure valve 50 is arranged in the timing transmission device right below the transmission piece 20, and the air-tight membrane 204 is arranged between the transmission piece 20 and the straight rod 52.
The time setting of the timer can be achieved by rotating the timer about the axis 601 of the timer support 60 before it is operated. During the rotation, the first interference portion 11 of the timing transmission device passes through the receiving portion 41, so as to press the transmission member 20 received in the receiving portion 41, such that the transmission member 20 presses the straight rod 52 to approach the first lower receiving chamber 202, thereby driving the valve plate 51 to be separated from the contact with the separation plate 205, and pressing the spring 53 to be in a compressed state. At this time, the gas in the gas inlet pipe 300 may flow to the gas outlet pipe 400 through the first lower chamber 202, the through hole 206, the second lower chamber 203 and the small hole 401, thereby realizing the supply of the gas. At the same time, the transmission member 20 will also be held by the holding rod 33 of the holding member 30, so that the valve sheet 51 is always out of contact with the separation plate 205, ensuring continuous supply of the gas, and the transmission member 20 is not in contact with the first interference part 11.
After the timer is set, the timer starts to work, and the timer slowly rotates in the opposite direction, and when the timer returns to the original position, the timing is finished. When the timing is over, the second interference part 12 of the timing transmission device will dial the dial rod 31 of the holding member 30, so that the holding rod 33 releases the transmission member 20. At this time, the straight rod 52 of the pressure valve 50 will move away from the first lower chamber 202 under the elastic recovery of the spring 53 until the valve plate 51 of the pressure valve 50 abuts against the partition plate 205, thereby cutting off the supply of the fuel gas.
The gas safety valve of the invention is provided with the timer bracket and the timing transmission device in the upper chamber 201, and the timing transmission device separately arranges the first interference part 11 and the second interference part 12 of the fixing plate 10 and the transmission part 20 and the clamping part 30 on the bearing plate 40, so that the transmission part 20 does not always abut against the first interference part 11 in the operation process of the timer, and the opening of the positive pressure valve in the gas safety valve is kept through the clamping of the clamping part 30. Therefore, the counter-acting force of the transmission part 20 to the timer in the working process of the timer is avoided, and the service life of the timer is prolonged.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes that can be directly or indirectly applied to other related technical fields using the contents of the present specification and the accompanying drawings are included in the scope of the present invention.
