Abstract

The utility model relates to a drainage device of air filter, which is installed on the outlet of the drinking cup, and the drinking cup is positioned at the lower end of the air-filtering pressure reducer of the compressed air filter. The valve core with sealing ring and spring are matched with the valve base, and the valve base and the drinking cup with sealing ring and gasket are jointed into an entirety by the assembling cap. The discharge valve seat is also connected with a live lock catch with counter spring, and the live lock catch is connected with the assembling cap and matched with the fixed lock catch handle of the valve core. The drainage device can occlude the air and automatically drain water, and when the system keeps working and the drinking cup is accumulated with a lot of sewerage, the sewerage can be drained by hands. If the lock catch handle is locked on the live lock catch, the water discharge outlet can not be opened no matter the air is occluded or not, and the sewerage must be drained by hands. Because the occlusion automatic water drainage and the manual water drainage can be interchanged, the water drainage function has diversification, the use is easy and safe, and the various requirements and operating habits can be satisfied. The sewerage can not splash in water drainage, and the sewerage can be drained to a permanent position by the flexible pipe and the working environment is avoided being polluted.

Description

The drainage arrangement of air cleaner

Technical field

The utility model relates to the parts of a kind of air cleaner or air filtration pressure-reducing valve water tumbler bottom, by the drainage arrangement of these parts with the air cleaner of the discharge of the moisture in the compressed air.

Background technology

The patent No. 01246536.4 " jettison gear of air cleaner " is though also provide a kind of jettison gear simple to operate, easy to use, but its function singleness, only can be by manual operations, can't satisfy the many-sided demand of user, sewage can not draw and is put into the fixed position when discharging water, but disorderly spatter the working environment around polluting everywhere.

Summary of the invention

Technical problem to be solved in the utility model is: the drainage arrangement that a kind of air cleaner is provided, has multiple drain function, and can change mutually between various drain functions, satisfy many-sided demand of user, be put into any fixed position and can draw during sewage discharge, avoid working environment to be polluted.

The technical scheme in the invention for solving the above technical problem is: the drainage arrangement of air cleaner is cooperated with valve seat by the spool that has sealing ring, spring, valve seat connects into whole the composition with the water tumbler of band sealing ring, packing ring with spelling cap base, the livelock button that also is connected with the band spring on the described valve seat is connected with spelling cap base, and cooperates with the lock catch shank fixed on the spool.

Compared with prior art, advantage of the present utility model is: this drainage arrangement drain function is many, but manual drainage has also manually draining of air pressure during work, draining automatically when stopping the supple of gas or steam, if lock catch shank is locked on the livelock button, can not draining when stopping the supple of gas or steam, each drain function can be changed mutually, and the automatic draining of stopping the supple of gas or steam is convertible into manual drainage, easy to use, function is many, can satisfy the requirement of user because of different operating environment and operating habit.Because of lock catch shank is arranged, can disorderly not spatter everywhere when making sewage discharge simultaneously,, can avoid working environment to be polluted with the sewage ejectment to the fixed position during draining, have environment-friendly function if in lock catch shank, connect flexible pipe.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

In the middle of the lock catch shank 5 shoulder hole, screw are arranged, uniform four arc openings 14, snap close 15 are arranged on the top edge wall.

In the middle of the livelock button 8 is shoulder hole, has four of uniform band opening protrudingly to buckle 6 on the outer surface, and outside flange and four uniform openings are arranged on the top edge wall, and opening communicates with opening on the four protruding buttons 6.

Spelling cap base 7 outer surfaces are waveform, and there is shoulder hole the centre, and the upper end is a screw, and the lower end is a through hole, and four uniform concave surfaces are arranged on the through-hole wall, and the concave edge place forms flange.

Livelock button 8 inserts lock catch shanks 5 upper ends, and four protruding buttons 6 on it are embedded in four arc openings 14 on the lock catch shank 5, and livelock button 8 is connected in aggregates with lock catch shank 5.The spool 1 outer spring 10 that is with, the discharge valve seat 2 that with the centre ladder hole is arranged, is placed with sealing ring 11,3 cooperates, spelling cap base 7, discharge valve seat 2 usefulness on it water tumbler 13 of screw thread and band sealing ring 12, packing ring 9 be fixed into integral body, utilize the flange on the livelock button 8 of being with balancing spring 4 to be held on the flange of spelling cap base 7 inwalls, spool 1 is not held and is inserted in lock catch shank 5 intermediate throughholes, and the riveting knot is fixed on the lock catch shank 5.

During work, feed operating air pressure in the water tumbler 13, act on the spool 1, when downward atmospheric pressure during greater than the reaction force of spring 10, then spool 1 moves down, and shuts discharge outlet, makes water tumbler 13 be in not draining of sealing state, if stop the supple of gas or steam, do not have operating air pressure in the water tumbler, spool 1 resets under spring 10 effects, and discharge outlet is opened, the sewage and the impurity that gather in the water tumbler are discharged from, as shown in Figure 2.

If system's continuous operation always, and gathered more sewage in the water tumbler, and at this moment can adopt manual drainage, arrest lock catch shank 5 with hand, and firmly upwards push away, when thrust when making the downward atmospheric pressure of spool 1, move discharge outlet on the spool 1 and open, ponding just is excluded, unclamp hand then, spool 1 resets under the effect of air pressure, and discharge outlet is shut, and water tumbler 13 is in sealing state again.

If lock catch shank 5 is pulled down on earth, and half-twist, four protruding buttons 6 are locked on the livelock button 8 over against four snap closes, 15 lock catch shanks 5, as shown in Figure 3, at this moment act on the counter-force of balancing spring downward on the spool 14, all the time greater than the counter-force that acts on the spring 10 that makes progress on the spool, make spool 1 be in sealing state all the time, no matter have or not air pressure to exist in the water tumbler 13, discharge outlet all can not be opened like this, and the ponding in the water tumbler can not discharged.If want draining must carry out manual drainage, at this moment arrest lock catch shank 5 with hand, and firmly upwards push away, when reaction force that thrust is produced greater than balancing spring 4 and atmospheric pressure, move discharge outlet on the spool 1 and open, water accumulation is excluded, and the spool 1 of loosing one's grip then resets under the effect of balancing spring 4 power and air pressure, discharge outlet is shut, and water tumbler is in sealing state again.

Automatic draining and the manual drainage of stopping the supple of gas or steam is interchangeable, lock catch shank 5 can be locked in location on the livelock button 8 when manual, moves up and down with hand push lock catch shank 5 drive spools 1 again.When stopping the supple of gas or steam automatic draining, lock catch shank 5 just can not pin livelock button 8, half-twist to make its dropout, and promptly four protruding buttons 6 embed in four arc openings 14, otherwise spool 1 just can not upper and lowerly automatically move.
