Abstract
The utility model belongs to the technical field of gas transporting and distributing equipment, and discloses a quick-opening blind flange filter. The quick-opening blind flange filter is characterized by comprising a gas inlet, a gas outlet and a sleeve body of a filtering core sleeve; the sleeve body is provided with a sewage exhaust valve and an emptying valve; the top end of the filtering core sleeve is provided with a blind flange; the outside of the inner wall of the blind flange is provided with a plurality of grooves, and the inside is provided with a boss; a core plate is in contact with the boss of the blind flange, and the outside diameter of the core plate is provided with convex teeth, and the convex teeth are matched with the grooves; the sealing ring is arranged inside the core plate, and a handle is arranged outside the core plate; and the positioning clamp block is arranged outside the core plate. The utility model has the advantage that the top end of the filtering core is connected and sealed with the clasp-shaped structure of the blind flange by the core plate, thus the quick-opening blind flange filter is simple to install, convenient to maintain and replace the filtering core, good in sealing performance, and safe to use.
Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of fast-opening blind filter.
Background technique
Be used for the gas filter in the fuel gas transportation pipeline system, its objective is particle, impurity in the purification separation filtration combustion gas, guarantee the normal operation of equipment such as cut-off valve, pressure governor, flowmeter.Gas filter comprises the cylindrical shell that has suction port, air outlet and filter core sleeve, and cylindrical shell is provided with blowdown valve and exhaust-valve.The flange on filter core sleeve top and plane blind plate seal with bolt connection, cushioning.When replacing or cleaning filter core, Bolt dismantling around the blind plate of plane need be got off just replaceable or cleaning.Service time one is long, when replacing or cleaning filter core, demounting bolt, twists bolt because of reasons such as corrosions and requires great effort very much, causes and changes the difficulty increasing, wastes time and energy, and influences work efficiency.
The model utility content
Problem to be solved in the utility model just provide a kind of simple in structure, be convenient to keep in repair and the fast-opening blind filter of renew cartridge more.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the cylindrical shell that has suction port, air outlet and filter core sleeve, cylindrical shell is provided with blowdown valve and exhaust-valve, the top of described filter core sleeve is provided with inner wall outside and has the blind plate that some grooves, inwall inboard are provided with boss, the central layer that external diameter is provided with the double wedge that is complementary with groove contacts with the boss of blind plate, and the inboard of central layer is provided with seal ring.
Its additional technical feature is: the arranged outside of described central layer has handle; The arranged outside of described central layer has positioning wedged block.
Fast-opening blind filter provided by the utility model, the top of filter core sleeve adopt central layer to be connected sealing with the snap ring shape structure of blind plate.It is good during installation filter core to be put into the cylindrical shell internal fixation, hold handle, the double wedge of central layer is aimed at the groove of blind plate, push inwards then central layer is contacted with the boss of blind plate, firmly rotate central layer again, double wedge and groove are staggered can fix central layer and blind plate, and this moment, seal ring played seal action.Handle rotation central layer is held in maintenance and more during renew cartridge, makes double wedge relative with groove, is pulled outwardly out central layer and gets final product, and uses very simple, laborsaving.And the arranged outside of central layer has positioning wedged block, after installing central layer, snaps in positioning wedged block and can prevent that the central layer rotation from producing gas leakage.

Fig. 2 is the A of fast-opening blind filter---the A cut-away view.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model fast-opening blind structure of filter and working principle are described in further details.
As shown in Figure 1, the utility model fast-opening blind filter comprises cylindrical shell 1, cylindrical shell 1 has suction port 2, air outlet 3, filter core sleeve 4 and exhaust-valve 5, the top of filter core sleeve 4 is provided with the blind plate 7 that inner wall outside has some grooves 6, the central layer 9 that external diameter is provided with the double wedge 8 that is complementary with groove 6 contacts with blind plate, and the arranged outside of central layer 9 has handle 10 and positioning wedged block 11.As shown in Figure 2, blind plate 7 inwall inboards are provided with boss 12, and central layer 9 contacts with boss 12, and the inboard of central layer 9 is provided with seal ring 13, and cylindrical shell 1 is provided with blowdown valve 14, is provided with filter core 15 in the cylindrical shell 1.
It is good during installation filter core 15 to be put into cylindrical shell 1 internal fixation, hold handle 10, the double wedge 8 of central layer 9 is aimed at the groove 6 of blind plate 7, push inwards then central layer 9 is contacted with boss 12, firmly rotate central layer 9 again, double wedge 8 and groove 6 are staggered can fix central layer 9 and blind plate 7, and this moment, seal ring 13 played seal action.Handle 10 rotation central layers 9 are held in maintenance and more during renew cartridge 15, make double wedge 8 relative with groove 6, are pulled outwardly out central layer 9 and get final product.And after installing central layer 9, snap in positioning wedged block 11 and can prevent that central layer 9 rotations from producing gas leakage.
Claims (3)
