Description

Machinery time-controlled urinal watering valve

This product belongs to mechanical field.Be used for the lavatory urinal is carried out semi-automatic flushing.

It is the ball valve that has the mechanical type timed unit.It is installed on the flushing line of urinal.After pressing valve handle, through about 5 seconds, ball valve is just opened automatically, passes through about 15 seconds again, and valve is closed again automatically.Thereby finished semi-automatic flushing to urinal.

Fig. 1 is the schematic diagram of this product.Internal gear 16, planetary gear 17 and central gear 18 are formed the fixing planetary gear mechanism of internal gear.The gear ratio of internal gear and central gear is 4, so gearratio is 5.Central gear 18 connects with main shaft 14.Main shaft 14 can only (refer to observe from handle 19, down together) 324 ° (seeing partial view II and C-C sectional drawing) of rotation clockwise from reset condition (being shown position) under the restriction of positive stop key 26.Main shaft 14 connects with clockwork spring 15.When main shaft 14 in reset condition following time, clockwork spring 15 promptly screwed for 3.1 weeks, this moment, it provided counter-clockwise direction torque 3.9kgcm to main shaft 14.Clockwork spring 15 adopts high-strength spring steel to manufacture, wide 12MM, and thick 0.5MM is about 1.33M.

When handle 19 clockwise directions rotated 65 °, main shaft 14 just clockwise direction rotated for 0.9 week (promptly 324 °), and the counter-clockwise direction torque that 15 pairs of main shafts 14 of clockwork spring this moment provide rises to 5kgCM.Main shaft 14 is gone back and ratchet 13 connects.Ratchet 13 interrelates by ratchet 11 and gear 12, and gear 12 can rotate on main shaft 14.When ratchet 13 clockwise directions rotated, gear 12 was motionless, when ratchet 13 counter-clockwise direction are rotated, can together rotate (seeing the B-B sectional drawing) by driven gear 12.Gear 12 and gear 10 have been formed speed increasing gear and have been paid.Gear 10 and pointed tooth gear 6 are coaxial, and pointed tooth gear 6 and escapement clamp 5 and inertia pendulum 4 have been formed the release catch type reducing gear.Change the dynamic moment of inertia of inertia pendulum 4, just can change the rotating speed of pointed tooth gear 6.There is cylindricality short key 9 in garden to extend into the annular keyway interior (seeing the B-B sectional drawing) of ratchet 13 on the ratchet 8.Ratchet 8 and valve shaft 2 connect.Valve shaft 2 can only be from reset condition clockwise direction half-twist (seeing partial view I and A-A sectional drawing) under the restriction of positive stop key 25.The spheroid 1 of valve shaft 2 and ball valve links.Under reset condition, ball valve is closed.Valve shaft 2 is gone back and clockwork spring 3 connects.Under reset condition, clockwork spring 3 promptly screwed for 2 weeks, and valve shaft 2 was provided the clockwise direction torque of 2.1kgCM.But because the annular keyway on the ratchet 13 is to the stopping of the short key 9 on the ratchet 8, and the torque (3.9kgCM) of clockwork spring 15 at this moment is greater than the torque (2.1kgCM) of clockwork spring 3, so valve shaft 2 does not rotate.Clockwork spring 3 is made by high-strength spring steel, wide 5MM, and thick 0.5MM is about 0.66M.Ratchet 8 interrelates by ratchet 20 and gear 7, and gear 7 can rotate on valve shaft 2.When ratchet 8 clockwise directions rotate, can together rotate by driven gear 7, when ratchet 8 counter-clockwise direction were rotated, gear 7 was motionless.Gear 7 and gear 21 have been formed speed increasing gear and have been paid.Gear 21 and pointed tooth gear 22 are coaxial, and pointed tooth gear 22 and escapement clamp 23 and inertia pendulum 24 have been formed the release catch type reducing gear.

Narration is when depressing handle 19 and unclamping its course of action when freely turning round of personal order below.

After depressing handle 19, main shaft 14 and ratchet 13 clockwise directions rotate 324 °, and the counter-clockwise direction torque that 15 pairs of main shafts 14 of clockwork spring this moment provide increases to 5kgCM by 3.9kgCM.In this process, gear 12 is motionless, so can not hinder the rotation of main shaft 14.Because this moment, the annular keyway of ratchet 13 no longer stopped the short key 9 on the ratchet 8, thus ratchet 8, valve shaft 2 and ball valve spheroid 1 just under the effect of clockwork spring 3, the clockwise direction rotation, thus ball valve is opened gradually.This moment gear 7, gear 21 and by pointed tooth gear 22, escapement clamp 23, inertia pendulum 24 escapements of forming all together in company with rotating and swing, thereby the speed that makes ball cut down unlatching is controlled.When ball cut down spheroid 1 and rotates about 65 ° by the home position clockwise direction, ball cut down and begins to open, and this process takes about 4 seconds.When rotating 25 ° again, cut down door and open fully.Whole process needed for 5.5 seconds approximately.When ball cut down standard-sized sheet, the clockwise direction torque that 3 pairs on clockwork spring cuts down door-hinge 2 to be provided was reduced to 1.83kgcm by 2.1kgcm.The inside nominal diameter that ball cuts down is taken as 19mm, and tap water pressure is 3kg/cm ², the driving torque that this moment, ball cut down is that the 1.2kgcm(computational methods are referring to mechanical engineering manual the 14th volume 78-74)

After unclamping hand, clockwork spring 15 drives main shaft 14, handle 19 and ratchet 13 and turns round along counter-clockwise direction, this moment gear 12, gear 10 and by pointed tooth gear 6, escapement clamp 5, inertia pendulum 4 escapements of forming all together in company with rotating and swing, thereby main shaft 14 rotating speed are controlled.When main shaft 14 has turned round 234 ° (324 °-90 °=234 °), the annular keyway on the ratchet 13 just with ratchet 8 on short key 9 contact once more.This process takes about 17 seconds.When main shaft 14 continued revolution, ball valve was just closed gradually.This moment, gear 7 was along with ratchet 8 rotates.Passed through about 1.5 seconds, ball valve is closed fully again.Pass through about 4 seconds again, whole device returns to reset condition.Whole process takes 22.5 seconds approximately, and wherein ball valve has been opened 14.5 seconds (wherein the time of complete opening is 11.5 seconds) altogether, and this is very abundant to flushing toilet bowl.

Fig. 2 is the assemble schematic of this product, ratio 1:1.Main shaft 14 connects with ratchet 13, clockwork spring 15.Ratchet 13 interrelates by ratchet 11 and gear 12.Gear 12, gear 10, pointed tooth gear 6 and inertia pendulum 4 are formed reducing gear.

Valve shaft 2 is enclosed within the main shaft 14, and valve shaft 2 connects with ratchet 8, clockwork spring 3.Ratchet 8 interrelates by ratchet 20 and gear 7.Gear 7, gear 21, pointed tooth gear 22 are formed reducing gear.

Ratchet 8 and ratchet 13 interrelate by the short key of ratchet 8 and the annular keyway of ratchet 13.When cutting down door-hinge 2 and rotating, the ball that can drive the left side cuts down spheroid 1 and rotates, and opens or closes thereby ball cut down.The operating principle of whole device as previously mentioned.

Perishable damage is immersed in the water entirely in control and executing agency that present normally used water tank type flush toilet has following shortcoming: a to cut down door; The b hydraulic pressure and the water yield are inadequate; The c pulling is cut down behind the door, and the water in the water tank almost pours urinal immediately, makes the normal addle of being spattered not as good as dodging of user; The d price is more expensive.And the utility model has been avoided these shortcomings basically.

With the ball valve in above-mentioned change into cock cut down also can, but be advisable to adopt ball to cut down, rotate flexibly because of ball cuts down, required rotating torque is little.Can adopt commercially available standard ball to cut down basically, need only revise a little being suitable for and link the body part of cutting down of casting with the mechanical type timed unit.

The mechanical type timed unit is very similar to clockwork, and manufacturing technology is ripe.
