Abstract

The utility model belongs to a flushing valve device used for flushing the urinal, which is composed of a diaphragm type two-position two-way main valve, a diaphragm type two-position two-way pilot valve, a conduit and an air chamber. Compressed air pushes the diaphragm of the pilot valve to open the pilot valve port when foot steps on the air chamber, which makes a container chamber drain and the main valve port open and drain. The pilot valve and main valve close in turn when the air chamber is loosened. The utility model has the advantages of small size, light weight, low precision for manufacture, no leakage, different water flushing quantity of feces and urine.

Description

Foot washing valve

The utility model belongs to the irrigator valve apparatus of a kind of lavatory urinal.

Cistern flushing is used in the lavatory more at present, and there is following shortcoming in it: 1. valve closing does not sternly leak; 2. the large and small water of putting with amount that just dashes; 3. dislike the stay cord handgrip unhygienic owing to people in the communal toilet, do not draw water tank, make urinal often have ight soil; 4. to turn round greatly after an action of the bowels and draw water tank.

China utility application CN86202264 and CN86201787 have proposed structure separately, but have still had perfect inadequately place for overcoming three shortcomings in above-mentioned prostatitis.Concerning CN86202264,1. complex structure has 37 parts, and the assembling more complicated makes relatively difficulty of maintenance; 2. two sliding rings are arranged, and it not only requires fitting face that higher precision and fineness are arranged, and the time one is long, will leak because of wearing and tearing; 3. also have two springs, time one length will lose efficacy in corrosion, and with being threaded, assembling is difficulty relatively on two vertical direction for the problem that CN86201787 equally also exists sliding ring and spring to cause, particularly a tee piece, correspondingly keeps in repair also difficulty; Its pedal structure is not compact yet, bad layout.

The purpose of this utility model is that a kind of flushing valve will be provided, and it is relatively simple for structure, no fretting wear part, and the accuracy of manufacture is less demanding, can overcome the shortcoming of existing lavatory water tank commonly used without spring in the valve.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.Among the figure:

1. 9. gland of main valve body

2. big diaphragm is conduit 10.

3. filter (11) air bag

4. bead (12) pedal

5. middle plate (13) back-moving spring

6. cover (14) positive stop

7. Small diaphragm-piece (15) button

8. diaphragm (16) back pressure spring

Structure of the present utility model is made up of a diaphragm type bi-bit bi-pass main valve (among the figure 1,2) and a diaphragm type bi-bit bi-pass pilot valve (among the figure 5,6,7,8).A filter can be used in main valve diaphragm throttle orifice the place ahead, and pilot valve valve rod one end is fixed a clamping diaphragm, and the other end is fixed a non-clamping diaphragm.Can give tensioning clamping diaphragm 8., pilot valve is closed, spring (16) is available can.The air chamber of pilot valve clamping diaphragm is connected with an air bag through a pipe, so that Pneumatic pressure operated pilot valve to be provided.

Operating principle of the present utility model is, at first is full of room by press water through big diaphragm throttle orifice, and big diaphragm is closed the main valve valve port under the effect of pressure reduction.When riding air bag, 7., 8. compressed air promote the pilot valve diaphragm through conduit, opens poppet port, and the current direction main valve in the room is managed down.Because the throttling action of throttle orifice, opposite pressure reduction appears in big diaphragm both sides, and the main valve valve port is opened, bath.When loosening air bag, the pilot valve diaphragm resets, and poppet port is closed, but the main valve valve port can not close immediately, has only when the water of throttle orifice is full of volume again, and big diaphragm is just closed the main valve valve port, thereby has the time-delay closing effect.Like this, foot-operated air bag is finished once flushing.Replace covering 6 with lid shown in Figure 2, promptly become on the other hand by flushing valve.

The utility model number of parts is less, and is relatively simple for structure; Adopt flat seal, no fretting wear part requires low to the accuracy of manufacture. Can not adopt spring reset. Pedal is small and exquisite, flexibly connects, and can be placed on corner, urinal the place ahead, foot-operated need not turning round. Because this flushing valve directly is connected with penstocks, has saved water tank, volume is little, and is in light weight, and installation and maintenance are convenient. Adopt clamping diaphragm switch main valve valve port, stroke is short, and sealing is reliable, and no Vent leaks. According to the length of compressing gasbag time, controllable size is just used different amount of flush water. 4. bead cooperates with the plastic tube upper end in defaecation pond, forms air insulated, prevents from polluting.

Claims

1, a kind of urinal irrigator valve apparatus, it is made up of a bi-bit bi-pass main valve and a bi-bit bi-pass pilot valve and catheter air bag, it is characterized in that pilot valve valve rod one end fixes a clamping diaphragm, the other end is fixed a non-clamping diaphragm, the air chamber of pilot valve clamping diaphragm is connected with a foot-operated air bag through a pipe, so that the compressed air operation to be provided.

2, according to the said irrigator valve apparatus of claim 1, it is characterized in that lid 6 and later part are removed, change lid and the button 15 of Fig. 2, can do manual flushing valve.
