Abstract
The utility model discloses a diaphragm pressure gauge, including a gauge stand (1), a gauge mirror (2), a diaphragm (3) and a machine core component; the machine core component includes an upper splint (4), a lower splint (5), a pointer (6), a fan-shaped gear shaft (7), a fan-shaped gear (8), a pointer gear shaft (9), a push rod (10) and a hair spring (11), and the interior of the gauge stand is provided with a cavity (12) which can contain the machine core component; the utility model is characterized in that: the cavity is a cavity body which is arranged between the upper plane of the lower splint and the lower plane of the upper splint and has the diameter larger than the outer diameter of the lower splint. The technical proposal can effectively save materials, reduce cost and allow the pressure gauge to be more stable under changing working condition.
Description
[technical field]
The utility model relates to a kind of tensimeter, what be specifically related to is a kind of diaphragm manometer.
[background technology]
Tensimeter uses on the various pipelines that pressure arranged, container, and diaphragm manometer is a kind of with the tensimeter of diaphragm as the induction medium pressure elements, uses very extensive.Diaphragm manometer comprises gauge stand, table mirror, diaphragm, cartridge assemblies, cartridge assemblies comprises train wheel bridge, lower plate, pointer, sector shaft, sector gear, pointer tooth axle, push rod are installed between train wheel bridge and the lower plate, on the pointer tooth axle hairspring is installed also, cartridge assemblies is installed in the cavity of gauge stand by train wheel bridge, lower plate.Its principle of work: when the pressure of diaphragm induction pipe or container inner medium, produce distortion, promote push rod, the sector gear that push rod promotes again to be installed on the sector shaft rotates, thereby sector gear push pointer tooth axle rotates and makes pointer rotate the demonstration force value, the effect of hairspring is to restoring force of pointer tooth axle, and guaranteeing pointer stable in rotation process and guaranteeing is not having under the pressure condition pointer get back to original position.Because cartridge assemblies is installed in the cavity of gauge stand by train wheel bridge, lower plate, its cavity diameter will cooperate with train wheel bridge, lower plate external diameter, adopt the enough diaphragm manometers of above-mentioned knot in the market, to being the same the train wheel bridge lower plane, diameter cooperates with the lower plate external diameter diameter of cavity that its gauge stand holds cartridge assemblies from the lower plate lower plane.The cavity of this structure makes the sidewall of gauge stand seem blocked up, waste material, and the material of general gauge stand is a metallic copper, and metallic copper so more makes manometric cost increase greatly owing to of many uses, inadequate resource, hold at high price.Simultaneously, because the cavity of this structure is narrow and small, the physical dimension of hairspring is restricted, and hairspring physical dimension is little, the number of turns of hairspring is just few, and its restoring force changes greatly, and tensimeter will seem not really stable under the variation operating mode.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model be to provide a kind of economical with materials, reduce cost, tensimeter change can be more stable under the operating mode diaphragm manometer.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of diaphragm manometer, comprise gauge stand, table mirror, diaphragm, cartridge assemblies, described cartridge assemblies comprises train wheel bridge, lower plate, pointer, sector shaft, sector gear, pointer tooth axle, push rod, hairspring, be provided with the cavity that can hold cartridge assemblies in the described gauge stand, it is characterized in that: described cavity be one between plane on the lower plate and train wheel bridge lower plane diameter greater than the cavity of lower plate external diameter.
Because the cavity that holds cartridge assemblies in the gauge stand between plane on the lower plate and train wheel bridge lower plane diameter greater than the lower plate external diameter, changed hold cartridge assemblies in the diaphragm manometer gauge stand in the market cavity diameter from the lower plate lower plane to the train wheel bridge lower plane being structure the same, that diameter cooperates with the lower plate external diameter.Under the identical situation of the same action effect of gauge stand profile,, under the situation that metallic copper holds at high price, adopt the diaphragm manometer of this structural cavity body just to effectively reduce cost like this because material has been saved in the increase of cavity; And the increase of cavity, the physical dimension of hairspring can strengthen, and the number of turns of hairspring is just many, and its restoring force changes little, and tensimeter will seem very stable under the variation operating mode.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
[embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and principle of work thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing, this diaphragm manometer comprises gauge stand 1, table mirror 2, diaphragm 3, cartridge assemblies, described cartridge assemblies comprises train wheel bridge 4, lower plate 5, pointer 6, sector shaft 7, sector gear 8, pointer tooth axle 9, push rod 10 are installed between described train wheel bridge and the lower plate, on the described pointer tooth axle hairspring 11 is installed also, cartridge assemblies is installed in the cavity 12 of gauge stand by train wheel bridge, lower plate.Described cavity be one between plane on the lower plate and train wheel bridge lower plane diameter greater than the cavity of lower plate external diameter.
Diaphragm manometer because material has been saved in the increase of cavity, under the situation that metallic copper holds at high price, adopts the diaphragm manometer of this structural cavity body just to effectively reduce cost under the identical situation of the same action effect of gauge stand profile like this; And the increase of cavity, the physical dimension of hairspring can strengthen, and the number of turns of hairspring is just many, and its restoring force changes little, and tensimeter will seem very stable under the variation operating mode.Adopt the diaphragm manometer of technique scheme, owing to possess the advantage of economical with materials, cost reduction, and, will bring very big economic benefit to the enterprise that produces diaphragm manometer because the market capacity of diaphragm manometer is huge; Product quality will be improved because tensimeter in that change can be more stable under the operating mode, will make, prolong serviceable life, and also will be subjected to users must welcome.
