Abstract
The utility model discloses a be equipped with the gas filter of online blowdown structure, gas filter's constitution includes body, filter core, end cap, its characterized in that the inner chamber bottom of body is equipped with one and link up the inside and outside right angle shape flow channel hole of cavity, the right angle shape flow channel hole drill way outside be equipped with a steel ball, the opposite side of steel ball is equipped with the blowdown screw rod, with the body passes through the screw thread mode and connects, the bottom of body is equipped with a screw hole, with the right angle shape flow channel hole communicate with each other, the utility model discloses gas filter's advantage lies in that the blowdown is convenient, and is clean high -efficient.
Description
Technical field
The utility model relates to a kind of pneumatic filter of autoamtic compressed gas filling machine, belongs to compressed natural gas filling equipment manufacturing technology field.
Background technology
Compressed natural gas filter is widely used in high pressure compressed natural gas equipment, is that natural gas cleans pure important leverage.Existing pneumatic filter is generally made up of body and filter core, connects threadably.In use, the screen surface of filter core can adhere to various filthy impurity, and cumulative in time, filter effect is had a greatly reduced quality, even has influence on the flow velocity of natural gas, cleans so need often to carry out blowdown to filter.The cleaning requirement of existing pneumatic filter first removes from filling machine, and filter core of then back-outing, rinse respectively body and filter core, process is cumbersome, affects operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumatic filter being provided with online pollution discharge structure, only needs to turn on blowdown screw rod, utilizes the gases at high pressure in aerating equipment, just the filthy impurity of the inside can be discharged body, both save time, laborsaving again.
For achieving the above object, the following technical scheme of concrete employing: a kind of pneumatic filter, the plug comprising body, be placed in the filter core of described chamber body, be connected with described body side screwed hole; It is characterized in that the intracavity bottom of described body is provided with the square runner hole inside and outside a through cavity; A steel ball is provided with outside described aperture, square runner hole; The opposite side of described steel ball is provided with blowdown screw rod; Described blowdown screw rod is threadedly connected with described body.
Above-mentioned pneumatic filter, is characterized in that the bottom of described body is provided with a screwed hole, communicates with described square runner hole.
Above-mentioned pneumatic filter, its advantage is:
Blowdown is convenient, clean and effective.Described pneumatic filter, when cleaned at regular intervals scrubbing, without the need to removing above filling machine, directly unscrews described blowdown screw rod, opens the 3 second time of filling machine, namely can wash away discharge in described body with the filthy impurity of screen surface.Easy to operate, operating efficiency also significantly improves.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In accompanying drawing, 1: body, 2: filter core, 3: plug, 4: square runner hole, 5: steel ball, 6: screwed hole, 7: blowdown screw rod
Detailed description of the invention
As shown in Figure 1, a kind of pneumatic filter, comprise body 1, filter core 2, plug 3, square runner hole 4, steel ball 5, screwed hole 6, blowdown screw rod 7, described pneumatic filter, body 1 is threadedly connected with filter core 2, forms filter body; Described plug 3 is placed in outside the fabrication hole of inlet channel, is threaded, and carries out encapsulation process with sealing ring with described body 1; Described square runner hole 4 is positioned at described body 1 intracavity bottom, and the impurity screening of accumulation flows through discharges herein; Be provided with a steel ball 5 outside described aperture, square runner hole 4, the opposite side of described steel ball 5 is provided with blowdown screw rod 7, is threadedly connected with described body; When filling machine normally works, described blowdown screw rod 7, by pushing described steel ball 5, makes close contact outside described steel ball 5 and aperture, described square runner hole 4, forms sealing state, to blowdown, unclamps described blowdown screw rod 7, utilize high pressure draught to wash away.
Above-mentioned pneumatic filter, described screwed hole 6, for connecting recovery channel, collects the filthy impurity and gas of discharging.
