Abstract
The utility model discloses a built-in valve for a gas meter, which comprises a rack, a motor, a valve seal assembly and a reduction gearbox. A bevel gear pair is arranged in the reduction gearbox; the lower end of the rack is movably connected with the valve seal assembly; the lower end of the rack is engaged with a cylinder gear at the lower portion of a bevel gear of the bevel gear pair to make the movement direction of the valve seal assembly consistent with the gas inlet/outlet direction; a main cylinder gear at the lower end of a main bevel gear of the bevel gear pair is engaged with a ratchet-pawl component when the valve is opened; and a pyramidal spring is arranged on the valve seal assembly. The built-in valve for the gas meter provided by the utility model is provided with the advanced slow-opening quick-closing technique so as to achieve the movement direction of the valve seal assembly consistent with the gas inlet/outlet direction and reduce the overall pressure loss, and is a novel built-in valve integrated with the advantages of the prior built-in valve.
Description
Technical field
The utility model relates to a kind of mainly being installed in the IC-card intelligent gas meter, the built-in valve of gas meter that the use of pipeline gas is controlled.
Background technique
Existing gas meter has a lot of deficiencys with built-in valve, has the moving direction of jam pot cover consistent with turnover gas direction, as screw-down valve, is to change down the pass formula slowly, and switch valve is unreliable, and under attack easily; The moving direction that jam pot cover arranged and turnover gas direction are 90 degree, have increased the complete machine crushing so again.
Summary of the invention
The purpose of this utility model is to provide a kind of motion of jam pot cover consistent with turnover gas direction for the deficiency that solves above-mentioned technology, and the built-in valve of the gas meter of slow opening fast shutting.
In order to achieve the above object, the built-in valve of a kind of gas meter that the utility model is designed, it comprises tooth bar, motor, jam pot cover assembly and speed reducer, in speed reducer, be provided with bevel gear pair, live with the jam pot cover assembly and be connected in the tooth bar lower end, the cylindrical gears engagement of the bevel gear bottom in tooth bar upper end and the bevel gear pair makes the moving direction of jam pot cover assembly consistent with turnover gas direction.The main cylindrical gears and the click parts of the drive bevel gear lower end of bevel gear pair mesh when driving valve.On the jam pot cover assembly, be provided with the awl spring.
When driving valve, motor driven gear rotation makes the click parts turn to bevel gear pair, thereby drives the bevel gear pair rotation, and bevel gear pair drives tooth bar and jam pot cover assembly at last and does motion away from valve port, finishes out valve; When closing valve, the motor driven gear counterrotating makes the click parts throw off bevel gear pair, thereby makes tooth bar and jam pot cover assembly press to valve port rapidly under the effect of awl spring force, finishes the pass valve.
The utility model is compared with existing built-in valve technology: it has possessed the advanced technology of slow opening fast shutting, owing to be in speed reducer, to have set up bevel gear pair, thereby the moving direction that has realized the jam pot cover assembly is consistent with turnover gas direction, has reduced the complete machine crushing; The jam pot cover assembly is connected with living of tooth bar, makes it when closing valve, and under the effect of awl spring force, jam pot cover is centering voluntarily, and jam pot cover is vertically pressed to valve port when guaranteeing to close valve.The built-in valve of the gas meter that the utility model provides is a kind of novel built-in valve of existing built-in valve advantage of collection and one.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional view.
Wherein: tooth bar 1, bevel gear pair 2, drive bevel gear 2-1, main cylindrical gears 2-11, driven wheel of differential 2-2, from cylindrical gears 2-21, motor 3, click parts 4, awl spring 5, jam pot cover assembly 6, jam pot cover 6-1, valve port 6-2, speed reducer 7.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the built-in valve of a kind of gas meter that present embodiment is described, it comprises tooth bar 1, motor 3, jam pot cover assembly 6 and speed reducer 7, in speed reducer 7, be provided with bevel gear pair 2, live with jam pot cover assembly 6 and be connected in tooth bar 1 lower end, the cylindrical gears 2-21 engagement of the bevel gear 2-2 bottom in tooth bar 1 upper end and the bevel gear pair 2.Make the moving direction of jam pot cover assembly 6 consistent with turnover gas direction.The main cylindrical gears 2-11 and the click parts 4 of the drive bevel gear 2-1 lower end of bevel gear pair 2 mesh when driving valve.On jam pot cover assembly 6, be provided with awl spring 5.
During work, the main cylindrical gears 2-11 and the click parts 4 of the drive bevel gear 2-1 lower end of bevel gear pair 2 mesh when driving valve, driven wheel of differential 2-2 lower end from the engagement of cylindrical gears 2-21 and 1 tooth bar.Click parts 4 when driving valve again, are flapped toward the cylindrical gears 2-11 of drive bevel gear 2-1 lower end, and are engaged with.When closing valve, throw off the main cylindrical gears 2-11 of drive bevel gear 2-1 lower end; Jam pot cover assembly 6 and tooth bar 1 are to live in being connected, and when closing valve, awl spring 5 makes jam pot cover 6-1 overcome stream pressure to fall rapidly and compress valve port 6-2, and under the power effect of boring spring 5, jam pot cover 6-1 is centering voluntarily, and jam pot cover 6-1 is vertically pressed to valve port 6-2 when guaranteeing to close valve.
