Background technique
Dry gas holder is widely used in the storage of industry and domestic gas, and it realizes handling up of coal gas by moving up and down of gas cabinet inner carrier.For the operational administrative personnel of gas cabinet, the understanding running position of gas cabinet piston, the situation of clear and definite gas holder gas storage volume are very important.Existing dry type gas holder holds indicating device and mainly contains Optic Fiber Gauge, mechanical level meter, ultrasound level meter and Radar level meter etc.Optic Fiber Gauge is the one end fixing wire rope on piston, and the wire rope the other end is fixed in the metering hinge wheel of level meter, drives reel to rotate when piston movement, and the signal of generation is exported by the signal changing cabinet appearance after level meter process into.Machinery level meter is the one end fixing wire rope on gas chamber piston, the wire rope the other end connects the driving gear of level meter, be with nutating gear to rotate when piston movement, the specific gear ratio of setting by the displacive transformation of wire rope be level meter indicator panel on the position of pointer.Ultrasound level meter and Radar level meter principle similar, all on top of gas cabinet and piston, arrange that ultrasound or radar send and receiving device respectively, by the time that measurement signal transmits, calculate offer for sale top and the distance of piston, then changed into cabinet appearance signal by formula and export to operator.
But existing dry type gas holder holds indicating device exists following defect: 1) Optic Fiber Gauge, mechanical level meter principle complexity, installation precision requires very high, to key equipment (as, metering hinge wheel and driving gear) too rely on, to lose cabinet appearance deixis once break down, cost is higher simultaneously; 2) ultrasound level meter and Radar level meter have employed ultrasound or reflection of electromagnetic wave technology, ideally measure comparatively accurate, but cost is very high, simultaneously very high to environmental requirement, antijamming capability is more weak, such as, often produces certain inclination during piston movement, thus often acceptable effect is bad or not accurate enough to cause reflected wave, can not be suitable for comparatively severe operating mode.
Summary of the invention
The object of this invention is to provide a kind of dry type gas holder and hold indicating device, this device clearly can react gas holder gas storage volume, and structure is simple, easy for installation, cost is low, and antijamming capability is strong, does not affect by tilting of the piston.
The technical solution adopted in the present invention is:
A kind of dry type gas holder holds indicating device, comprise the first magnet be fixed on piston, be located at the column arranged outside side plate and along the first magnets free scope, column inside is provided with hollow cavity, is provided with the second magnet and is full of liquid in hollow cavity, and the first magnet and the second magnet attract each other.
Further, in hollow cavity, the buoyancy of liquid to the second magnet equals the gravity of the second magnet self.
Further, the second magnet is spherical.
Further, column, liquid are all transparent, and the second magnet surface is colored.
Further, the side plate near column is provided with the graduation line of reflection gas cabinet capacity.
Further, graduation line is uniformly distributed between the lowermost end and top of piston stroke.
Further, the kinematical viscosity of hollow intracavity liquid is less than 1.0 × 10
-6m
2/ s.
The invention has the beneficial effects as follows:
1. piston moves drive first magnet and moves, and the first magnet moves attraction second magnet and follows movement, and the second magnet leaching is unrestrained in a liquid, be convenient to overcome gravity and follow movement, by observing the position of the second magnet, the particular location of piston can be known, i.e. known gas holder gas storage volume; This apparatus structure is simple, easy for installation, cost is low, and antijamming capability is strong, does not affect by tilting of the piston.
2. the buoyancy of the second magnet and gravity are cancelled out each other, and when following the first magnet movement, eliminate the impact of buoyancy and gravity to greatest extent, the second magnet and the first magnet are reduced at the error span of vertical direction, and display result is more accurate.
3. spherical full symmetric, ensure that the second magnet rises identical with suffered resistance during decline, the measurement effect of piston rising and decline is stablized.
4. column, liquid-transparent, the second magnet is colored, is convenient to observe.
5. graduation line is set, accurately can reflects gas holder gas storage volume.
6., because the moving range of piston is uniform section, so the high-positive correlation of gas holder gas storage volume and piston, therefore graduation line is uniformly distributed.
7. the kinematical viscosity of hollow intracavity liquid is less than 1.0 × 10
-6m
2/ s(that is 20 DEG C time water kinematical viscosity), prevent liquid kinematical viscosity excessive, hinder the second magnet to follow the first magnet and move.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of dry type gas holder holds indicating device, comprise the first magnet 3 be fixed on piston 4, be located at the column 5 arranged outside side plate 7 and along the first magnet 3 the sphere of activities, column 5 inside is provided with hollow cavity, be provided with the second magnet 2 in hollow cavity and be full of the fluid that liquid 6(adopts harmonic motion viscosity as far as possible), the first magnet 3 and the second magnet 2 attract each other.Piston 4 moves drive first magnet 3 and moves, and the first magnet 3 moves attraction second magnet 2 and follows movement, and the second magnet 2 leaching is overflow in liquid 6, be convenient to overcome gravity and follow movement, by observing the position of the second magnet 2, the particular location of piston 4 can be known, i.e. known gas holder gas storage volume; This apparatus structure is simple, easy for installation, cost is low, and antijamming capability is strong, not by piston 4 obliquity effects.
In hollow cavity, the buoyancy of liquid 6 to the second magnet 2 equals the gravity of the second magnet 2 self.Buoyancy and the gravity of the second magnet 2 are cancelled out each other, and follow the first magnet 3 when moving, eliminate the impact of buoyancy and gravity to greatest extent, the second magnet 2 and the first magnet 3 are reduced at the error span of vertical direction, and display result is more accurate.
As depicted in figs. 1 and 2, in the present embodiment, the second magnet 2 is spherical.Spherical full symmetric, ensure that the second magnet 2 rises identical with suffered resistance during decline, the measurement effect making piston 4 rise and decline is stablized.
In the present embodiment, column 5, liquid 6 are all transparent, and the second magnet 2 surface is colored.Column 5, liquid 6 are transparent, and the second magnet 2 is colored, are convenient to observe.
As shown in Figure 2, in the present embodiment, the side plate 7 near column 5 is provided with the graduation line 9 of reflection gas cabinet capacity.Graduation line 9 is set, accurately can reflects gas holder gas storage volume.
As shown in Figure 2, in the present embodiment, graduation line 9 is uniformly distributed between the lowermost end and top of piston 4 stroke (for 10 ten thousand stere rubber film sealed dry type gas cabinets in figure, so graduation line 9 is designated as 0 at the lowermost end of piston stroke, graduation line is designated as 10 at the top of piston stroke).Because the moving range of piston 4 is uniform section, so the high-positive correlation of gas holder gas storage volume and piston 4, therefore graduation line 9 is uniformly distributed.
