Abstract
The utility model discloses a double-cylinder filter which belongs to liquid-filtering device. The double-cylinder filter comprises a left filtering shell, a right filtering shell, and a reversing valve connected between the left filtering shell and the right-filtering shell, wherein a filtering element is respectively arranged in the left filtering shell and the right filtering shell. The reversing valve in the double-cylinder filter is a dual three-way changeover ball valve, and a valve core of the dual three-way changeover ball valve is made of stainless steel. Compared with the prior art, the left filtering shell and the right filtering shell as well as the reversing valve connected between the left filtering shell and the right filtering shell in the double-cylinder filter provided by the utility model are respectively integrally cast, the structure is compact, the appearance is aesthetic, and batch production can be realized, therefore, cost is reduced. The valve core of the reversing valve of the double-cylinder filter adopts the stainless-steel ball valve, the surface of the valve core is smooth, the abrasion resistance is high, the deformation of the valve core can be obviously improved, and the valve core cannot deform until the leakage of the reversing valve. The double-cylinder filter has a simple structure and is convenient to operate.
Description
Technical field
The utility model relates to a kind of double-drum filter, belongs to fluid filtering device.
Background technology
Generator Set, blower unit, steel rolling unit are the large-scale technical equipments that electrical production, PETROLEUM PROCESSING, coal production and steel production industry are used.These large-scale units all adopt centralized lubricating system without exception.The function of lubricating system is to provide qualified lubricating oil to the operation of unit and abrading section (parts), realizes good lubricating, and reduces the wearing and tearing and the friction of unit relative movement part.This reduces parts damages and equipment fault (shutdown loss) for the operating efficiency, the energy efficient that improve unit, prolongs service life of equipment and all has crucial meaning.
Double-drum filter is the important component part of centralized lubricating system; monotubular filter filter core in the course of the work stops up in the time of to a certain degree need cleaning or change; stop host work; so not only lose time and more can not satisfy the needs of main frame continuous operation; double-drum filter has solved the defective of monotubular filter this respect effectively, under non-stop-machine situation capable of washing or more renew cartridge to guarantee the main frame normal and continuous operation.Its work characteristics is when a filter element obstruction needs to change, and does not need to stop host work, as long as open equilibrated valve and rotate reversal valve, the another filter can be worked, and changes the filter core that has stopped up then.
Double-drum filter is because of its particular performances, and the application on market at present more and more widely.But there is its fatal shortcoming in present double-drum filter, and cylindrical shell adopts seamless pipe, and most of cylindrical shells cause waste more greatly, and common reversal valve is revealed easily, uses to the user and causes very big difficulty.
In industrially developed country, double-drum filter carries out specialization by the specialized vendor and produces, product is realized standardization, seriation substantially, and this can make the double-drum filter product have higher design level and workmanship, reduces product cost simultaneously and shortens the manufacturing cycle.Yet in China, the design of double-drum filter and to make all be to be designed voluntarily by large-scale unit factory, single-piece is made, technical performance poor (complex structure and oil liquid leakage are serious) not only, and product quality does not ensure effectively that this situation can not satisfy the needs of China's technical merit development yet.
At present, double-drum filter filter cylinder major part all adopts seamless pipe or steel plate convolution to form, and production efficiency is low, the cost height.
The utility model content
The purpose of this utility model is to have overcome above shortcomings in the prior art, and a kind of novel double-drum filter is provided, and this double-drum filter good airproof performance has solved the problem that reversal valve leaks effectively.
To achieve these goals, the utility model has been taked following technical scheme.This double-drum filter comprise left filter housing, right filter housing and be connected left filter housing and right filter housing between reversal valve, in left filter housing and right filter housing, be respectively arranged with filter core.Described reversal valve switches ball valve for the duplex threeway, and the spool of spool for being made by stainless steel of ball valve switched in the duplex threeway.Described left filter housing, right filter housing and the duplex threeway switching ball valve that is connected between the two are single cast body, and connect into an integral body.
In terms of existing technologies, the utlity model has following advantage:
1) double-drum filter in the utility model carries out monoblock cast respectively to left and right sides two housings and connection reversal valve, compact conformation, and good looking appearance can be produced in batches, thereby reduce cost.
What 2) be connected in the utility model that reversal valve between the housing of the left and right sides selects for use is that ball valve is switched in the duplex threeway, and this ball valve sealing is good.The spool that ball valve is switched in the duplex threeway adopts stainless steel, and spool face is smooth, and the abrasion resistance height can obviously improve the spool distortion and leak until reversal valve, and is simple in structure, easy to operate.
Description of drawings
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure: 1, left filter housing, 2, the duplex threeway switches ball valve, 3, right filter housing, 4, filter core, 5, differential pressure transmitter device, 6, switch handle.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, this double-drum filter comprises left filter housing 1, right filter housing 3 and is connected reversal valve between left filter housing 1 and the right filter housing 3.In left filter housing 1 and right filter housing 3, be respectively arranged with filter core 4.What the reversal valve in the present embodiment adopted is that ball valve 2 is switched in the duplex threeway, and the spool of duplex threeway switching ball valve 2 is made by stainless steel, can make spool face smooth like this, the abrasion resistance height.Three-way diverter valve is provided with the switching handle, and inside is equipped with differential pressure transmitter device.
With left filter housing 1, right filter housing 3 be connected duplex threeway between the two and switch ball valve 2 and be single cast body, and connect into an integral body in the present embodiment, make compact overall structure like this, good looking appearance can be produced in batches, thereby reduce cost.
The operation principle of this double-drum filter is as follows: double-drum filter has two filter cylinders; the centre has a reversal valve to connect; has only a filter cylinder in work; warning device will be reported to the police after the filter core in the filter cylinder stops up; at this time do not need to shut down; as long as reversal valve is switched to another filter cylinder just can work on, change the filter core that stops up then.Double-drum filter mainly is made up of left and right sides filter cylinder, reversal valve, bearing, warning device, blowoff valve, sample valve etc.
More than the distributed network security control method of a kind of publicly-owned cloud service provided by the utility model is described in detail, used specific embodiment herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, part in specific embodiments and applications all can change.In sum, this description should not be construed as restriction of the present utility model.
