Description
Technical field
The utility model relates to field of flow meters, relates in particular to a kind of glass ball float flowmeter.
Background technology
Suspended body flowmeter is one of parts that are most widely used in current automation instrument.Along with the development of modern industry, the glass ball float flowmeter of classic method design can not adapt to existing demand.Exist specifically following problem: glass rotameter exists the frangible risk of glass tube in the process of using and transporting, especially without guide frame float, be used for gas.In addition, because the impurity in liquid is too much, in the process of glass ball float flowmeter of flowing through, impurity can be retained in glass chamber, hinder the accuracy that float or liquid move and affects measurement result, also can indirectly shorten the serviceable life of glass ball float flowmeter.
A kind of filter-type glass rotameter is disclosed in Chinese invention patent prospectus 200910198716.6, comprise water inlet pipe, flow regulation chamber, be provided with stainless (steel) wire filtrator, and stainless steel wire web filter is arranged in filtrator cavity between water inlet pipe and flow regulation chamber.This invention a little to improve, can change flowmeter to small-sized glass rotors formula flowmeter water inlet end in operational process, owing to having in water compared with large impurity, the stuck phenomenon of stainless steel float is occurred.
But, the glass rotameter of said structure is not made improvement to the situation of glass shell cracky, in the process of using, the pressure ratio that glass shell can bear is lower, or than being easier to occur breakage, when broken, glass flashes and also may cause hurting sb.'s feelings, and filtrator is installed also will be changed flowmeter structure a filtrator cavity is set, and still exists certain inconvenience.
Utility model content
Technical problem to be solved in the utility model is for the above-mentioned state of the art, to provide a kind of energy reinforced glass shell breakage-proof ability, improves the glass rotameter of glass flowmeter life-span and convenient changing filtration unit.
For achieving the above object, the utility model provides following technical scheme: a kind of glass ball float flowmeter, include top base, bottom base, water inlet pipe, on described, glass tube is installed between bottom base, on described bottom base, be provided with filtrator, described filtrator is connected with water inlet pipe, described filtrator includes screen pack and elasticity installation component, described filtration net cover is located on elasticity installation component, described elasticity installation component comprises not closed steel loop, spring, cavity pipe, described spring fitting is in cavity pipe, end, described not closed steel loop two ends extends in described cavity pipe, and connect into complete ring-type with described spring, and be provided with antibreaker on described glass tube.
The glass ball float flowmeter that adopts said structure, the pressure that glass shell can bear more originally exceeded a lot, was not easy to occur damaged, when liquid is flowed through flowmeter, impurity can be filtered outside, is not easy to cause the pollution in glass tube, the situation that also can not cause float to be stuck.And by the filtration unit of this structure, can change easily filtrator, as long as utilize the scalability of spring just can realize, install and replace, without complicated operation and instrument, very convenient and quick.
As concrete technical scheme of the present utility model, described antibreaker consists of transparent colloid layer.
Further, described transparent colloid layer is set in outside glass tube, and fits with described glass tube.
By using this material, the shock of external force to glass tube can be effectively reduced, and the lethality of fragment after glass tube explosion can be lowered or eliminate, aspect safety case, promote to some extent.
As concrete technical scheme of the present utility model, described transparent colloid layer is cylindric, both ends open, and its cavity shape and glass tube form fit, its intracavity diameter is greater than diameter glass tube.
Adopt this shape and size, transparent colloid layer cover can closely be enclosed within on glass tube, is not easy to depart from.
Compared with prior art, the utility model has the advantage of: at glass tube, form safe protective covering outward, effectively reduced the impact of external force to glass tube, reduced the lethality that broken rear fragment causes, safe and reliable.And original filtrator has been made and having been changed, made its installation more simple and convenient, for the liquid of the glass tube of flowing through filters, improve its purity, be not easy to cause the pollution in glass tube, the situation that also can not cause float to be stuck, the serviceable life of greatly having improved flowmeter.

Embodiment
Below in conjunction with accompanying drawing embodiment, glass rotameter of the present utility model is described in further detail.
The spatial structure that has schematically illustrated out glass rotameter in the utility model embodiment of Fig. 1, include top base 1, bottom base 2, water inlet pipe 3, on described bottom base 2, be provided with filtrator 5, described filtrator 5 is connected with water inlet pipe 3, water inlet pipe 3 is threaded connection with bottom base 2 and is connected, its junction is provided with water inlet gasket circle 6, between described top base 1 and bottom base 2, glass tube 7 is installed, on described glass tube 7, be provided with antibreaker, described antibreaker is a transparent colloid layer 4, adopt transparent material, can not affect scale and reading on sight glass pipe 7.On described filtrator 5, be provided with elasticity installation component.Described transparent colloid layer 4 is cylindric; both ends open; its cavity shape and glass tube 7 form fit; intracavity diameter is slightly larger than glass tube 7 diameters, and is set in outside glass tube 7, and its interior wall energy and glass tube 7 outer walls are fitted; carry out anti-vibration protected; be not easy to occur breakage, once there is fragmentation, the fragment of the inside is also unlikely to splash out.
