Abstract

The utility model relates to a throttle valve, and aims at providing a throttle valve of a crust breaking cylinder. The throttle valve of the crust breaking cylinder comprises a pressure regulating valve, an air supply pipe, an external pilot pipe, a two-position three-way electromagnetic valve and a power control line corresponding to the two-position three-way electromagnetic valve. After the throttle valve of the crust breaking cylinder is adopted, the output way of the pressure of the crust breaking cylinder is changed into two-stage output as required, so that the air utilization efficiency of the crust breaking cylinder is greatly improved, the compressed air is saved, the air utilization efficiency of the crust breaking cylinder reaches the maximum, and the final aims of saving energy and reducing consumption can be further achieved.

Description

A kind of crust breaking cylinder air throttle
Technical field
The utility model is about a kind of air throttle, particularly a kind of air throttle that is specifically designed to crust breaking cylinder.
Background technology
The air consumption of crust breaking cylinder accounts for about 20% of whole plant compressed air usage quantity in the aluminum electrolysis industry, and is most important to the influence of whole factory energy consumption.Crust breaking cylinder can be the gordian technique of energy-saving field of pneumatic in the aluminum electrolysis industry with moral.Pneumatic system is being brought into play important effect because the adjusting of low, pollution-free, the easy care of cost, power output and working speed such as is very easy at advantage in industrial automation, but the energy consumption of crust breaking cylinder accounts for pneumatic system total energy consumption significant proportion and capacity usage ratio is not high.In today that energy problem becomes increasingly conspicuous, the energy-conservation of crust breaking cylinder has great significance to the energy-saving and cost-reducing of aluminum electrolysis industry.
Both at home and abroad stretching out with withdrawal of existing crust breaking cylinder adopted identical pressure output, and crust breaking cylinder stretches out to be broken the surface crust and need the input high pressure gas, and do not need high pressure gas during withdrawal, therefore, adopt uniform pressure to supply with crust breaking cylinder work, compressed air consumption is big, and waste is serious.
By at electrolyzer air feed branch road air throttle being installed, pressure, flow during to the crust breaking cylinder start reasonably mate control, and what can make crust breaking cylinder reaches maximum with gas efficient.
The utility model content
Main purpose of the present utility model is to overcome deficiency of the prior art, and a kind of air throttle that is specifically designed to crust breaking cylinder is provided.For solving the problems of the technologies described above, solution of the present utility model is:
A kind of crust breaking cylinder air throttle is provided, comprises relief valve, described crust breaking cylinder air throttle also comprises air-supply duct, external pilot pipe, two-position three way magnetic valve and corresponding two-position three way magnetic valve power control line; Two-position three way magnetic valve is respectively equipped with P hole, A hole and R hole, and an end of two-position three way magnetic valve is connected with the two-position three way magnetic valve power control line; Air-supply duct comprises inlet pipe and escape pipe, and the inlet pipe of air-supply duct is connected with the P hole of two-position three way magnetic valve, and the escape pipe of air-supply duct is connected with the A hole of two-position three way magnetic valve; Relief valve is installed between the inlet pipe of the R hole of two-position three way magnetic valve and air-supply duct, and the external pilot pipe is connected with the inlet pipe of two-position three way magnetic valve, air-supply duct respectively.
As further improvement, the tie point of described external pilot pipe and air-supply duct is between the tie point and P hole of relief valve and air-supply duct.
As further improvement, the control signal of described crust breaking cylinder air throttle is electrical signal.
Compared with prior art, the beneficial effects of the utility model are:
The crust breaking cylinder air throttle that the utility model provides changes the pressure of crust breaking cylinder into two-stage output as required, that improves crust breaking cylinder significantly uses gas efficient, the save compressed air, what make crust breaking cylinder reaches maximum with gas efficient, thereby reaches energy-saving and cost-reducing final purpose.
Description of drawings
Fig. 1 is structure composition diagram of the present utility model.
Reference numeral among the figure is: 1 two-position three way magnetic valve; 2 relief valves; 3 air-supply duct; 4 external pilot pipes; 5 two-position three way magnetic valve power control lines; 6 crust breaking cylinder air throttles.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Crust breaking cylinder air throttle 6 among Fig. 1 comprises relief valve 2, air-supply duct 3, external pilot pipe 4, two-position three way magnetic valve 1 and corresponding two-position three way magnetic valve power control line 5, described crust breaking cylinder air throttle 6 is installed on each electrolyzer crust breaking cylinder gas manifold, and the control signal of crust breaking cylinder air throttle 6 is electrical signal.Two-position three way magnetic valve 1 is respectively equipped with P hole, A hole and R hole, and an end of two-position three way magnetic valve 1 is connected with two-position three way magnetic valve power control line 5; Air-supply duct 3 comprises inlet pipe and escape pipe, and the inlet pipe of air-supply duct 3 is connected with the P hole of two-position three way magnetic valve 1, and the escape pipe of air-supply duct 3 is connected with the A hole of two-position three way magnetic valve 1; Relief valve 2 is installed between the inlet pipe of the R hole of two-position three way magnetic valve 1 and air-supply duct 3, external pilot pipe 4 is connected with the inlet pipe of two-position three way magnetic valve 1, air-supply duct 3 respectively, and the tie point of external pilot pipe 4 and air-supply duct 3 is between the tie point and P hole of relief valve 2 and air-supply duct 3.
Crust breaking cylinder air throttle 6 provided by the utility model has two kinds of operating mode:
(1) operating mode under 5 outages of two-position three way magnetic valve power control line:
Cut off the power supply down when two-position three way magnetic valve power control line 5 is in, two-position three way magnetic valve 1 is in normally off.P hole and the A hole of two-position three way magnetic valve 1 are in trip condition, and R hole and A hole are in channel status, and pressurized air enters relief valve 2 by air-supply duct 3 bypass, after relief valve 2 pressure regulation, enter the R hole of two-position three way magnetic valve 1 again, finally by the output of A hole, supply with gas consuming device.
(2) two-position three way magnetic valve power control line 5 connects the operating mode under the electricity:
Connect electricity down when two-position three way magnetic valve power control line 5 is in, two-position three way magnetic valve 1 is in normally open.P hole and the A hole of two-position three way magnetic valve 1 are in channel status, and R hole and A hole are in trip condition, and pressurized air directly enters the P hole of two-position three way magnetic valve 1 by air-supply duct 3, come out from the A hole, supply with gas consuming device.
