Abstract
The utility model relates to a water supply valve, particularly a water-saving water supply valve for a passenger train, which can effectively save water and comprises a fixed device. The utility model is characterized in that one side of a valve body (11) is provided with an overflow shut-off valve device controlled by an overflow pedal (12) and a timing shut-off valve device controlled by a timer (4), and an antifreezing stopping block (8) which can be adjusted is arranged on the valve body (11), in order to adjust the flow rate of frozen-free minimal long flowing water of the water supply valve. One end of a valve lock rod (6) is matched with a locking head (5), and the other end extends out, in order to manually rotate and open a water valve.
Description
Technical field
The utility model relates to a kind of water saving water supply valve, the especially a kind of railway passenger train water saving water supply valve that can effectively economize on water.
Background technique
At present, the water method is on the known railway passenger train: with a long leather hose (more than 20 meters), link from the valve head that adds well on the water inlet head of train, because of train dwelling time weak point, in order to give the passenger train filling up water or to go up water more, usually be after opening the water valve that adds the well limit earlier, go to connect water pipe adapter (because of the well that adds of dress water valve reaches more than 20 meters to the water inlet joint maximum distance of train) again, before connecting pipe, will drop down water for a moment in vain like this; In case the train water tank is filled it up with, the water that overflows pours off again (add the last water conservancy projects work that the water conservancy project people will be responsible for 3～10 joint carriages because of 1, can not in time close the valve that adds the well limit) in vain; When train will drive away, pull up joint earlier, remove to add well frontier juncture water valve again, drop down a lot of water again; Because of wintry weather cold, freezes again, must allow the water inlet running water, and each dependence artificially judges that the water flow of exempting to freeze is difficult for grasping, and causes out big flow running water that a lot of water are decreased in multithread for preventing the train water inlet.Therefore the water method will be wasted a lot of water on the existing railway passenger train, so that actual water use efficiency has only 50%～60%.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of water waste on the existing passenger train, a kind of passenger train water saving water supply valve that can effectively economize on water to be provided.
The purpose of this utility model can reach by following measure:
A kind of passenger train water saving water supply valve, comprise fixing device, a side that it is characterized in that valve body 11 is provided with by the spilling water shut-off valve assembly of spilling water pedal 12 controls and the timing shut-off valve assembly of timer 4 controls, also be provided with an adjustable antifreeze backstop 8 on the valve body 11, so that regulate the minimum running water flow that water supply valve exempts to freeze, one end of block of valve bar 6 cooperates with tapered end 5, and the other end stretches out, so that manual Unscrew water valve.
The purpose of this utility model can also reach by following measure:
In the described spilling water shut-off valve assembly, spilling water pedal 12 is connected with an end of lock lever 14, the other end of lock lever 14 is provided with stabilizing spring 3, and can promote to lock lever 14 and make tapered end 5 push locking bit to, lock lever 14 is fixed on the dunnage 2, one end of tapered end 5 is fixed on the lock lever 14, and can seesaw under the drive of lock lever 14, and the other end cooperates with an end of block of valve bar 6;
In the described timing shut-off valve assembly, timer 4 is provided with timer push rod 13, and an end of timer push rod 13 contacts with lock lever 14;
Described fixing device is by dunnage 2, and fixed cover 1 reaches fixedly grabs 15 formations, and fixed cover 1 is fixed on the dunnage 2, and fixed cover 1 is provided with fixedly grabs 15, so that water supply valve is fixed on the overflow pipe 16, and with spilling water mouth of pipe aligning spilling water pedal 12;
On the described block of valve bar 6 snap 7 is set, and links to each other with movable valve plug 9, movable valve plug 9 cooperates with fixed spool.
The beneficial effects of the utility model are:
1, under the prerequisite of the fundamental function that does not influence water supply valve, can be on to passenger train during the water full water or the timing water-feeding time then close water supply valve voluntarily.
2, the minimum water flow that provides water-supply apparatus to exempt to freeze reaches more than 80%～90% the utilization ratio of water, reaches water-saving purpose.
3, valve body structure is simple, and is easy to operate.

In Fig. 1,1. fixed cover, 2. dunnage, 3. stabilizing spring, 4. timer, 5. tapered end, 6. block of valve bar, 7. snap, 8. antifreeze backstop, 9. movable valve plug, 10. fixed spool, 11. valve bodies, 12. the spilling water pedal, 13. timer push rods, 14. lock levers, 15. fixedly grab, 16. overflow pipes.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, on an accurate movable valve plug 9, a block of valve bar 6 is set, an end of this block of valve bar 6 is provided with a stopper, the other end lengthening stretches out, so that manual Unscrew water valve, block of valve bar 6 is provided with a snap 7, and it can drive movable valve plug 9 and revolve and turn 90 degrees through-flow mouthful that closes spool voluntarily.
Be provided with one on the top of water supply valve and may be stuck on the overflow pipe 16 fixed cover 1 that fixing water supply valve is used, what be provided with fixing usefulness in the cover fixedly grabs 15, aims at spilling water pedal 12 with the water that overflow pipe 16 is overflowed.
When the block of valve bar 6 that manually turns clockwise places when fetching boiling water valve position, tapered end 5 is under the pushing of the stopper inclined-plane of block of valve bar 6,3 withdrawals of compression stabilizing spring, after the stopper of block of valve bar 6 is crossed tapered end 5 positions, tapered end 5 stretches out under the thrust of stabilizing spring 3, and block 6 revolutions of block of valve bar, make water valve be parked in open mode; Spilling water pedal 12 also places upper under the effect of stabilizing spring 3 simultaneously.After being added the water tank topped up with water, when water overflows from overflow pipe 16, the water that overflows falls to beating on spilling water pedal 12, spilling water pedal 12 moves downward under the momentum effect of falling into water, and by 5 withdrawals of lock lever 14 drive tapered ends, locking-valve bar 6 drives movable valve plug 9 and is rotated counterclockwise 90 degree voluntarily under the effect of snap 7, water valve cuts out voluntarily.
Again when water one side does not have water tank overflow pipe 16 on the row passenger train, just can't use spilling water control, at this moment can adopt timing controlled, when timer 4 set be timed to the time (being easy to obtain the timing of institute's amount of water according to different hydraulic pressure), timer push rod 13 is released, and by 5 withdrawals of block of valve bar 11 drive tapered ends, movable valve plug 9 is rotated counterclockwise 90 degree voluntarily under the effect of snap 7 equally, and water valve cuts out voluntarily.
When weather is cold, antifreeze backstop 8 adjustable position keep certain aperture to blocking the automatic contract fully of spool, make water supply valve still have certain water flow at close stance, and can regulate the position of antifreeze backstop 8 easily, with the minimum water flow that obtains to exempt to freeze, water supply valve is freezed, saved water again to greatest extent.
