Description
Technical field
A kind of spool is the utility model is related to, more particularly to a kind of new diverter valve spool.
Background technology
At present, the tap of the prior art divides water, its spool can be divided mainly into rotary spool and lifting by mode of operation
Formula spool.Wherein, rotary spool is to use moving valve plate and quiet valve block, coordinates valve rod to be turned on and off moving to realize its water route
Make；Rotation valve rod, then valve rod drive moving valve plate rotated relative to quiet valve block, the water hole for making to set on moving valve plate on quiet valve block with setting
The water hole put is coincided with the upper and lower or mutually staggered, so as to be turned on and off water route.
This rotary spool of the prior art, when carrying out shutoff operation, only valve rod rotate in place could be completely
Close its water route, but many users are when in use often due to various reasons（Such as rotation dynamics is inadequate, careless
Deng）, cause to fail valve rod rotateing in place, so as to cause tap the problems such as dripping, flowing water occur, in turn result in water resource
Waste.
Above-mentioned another kind pull-type spool also has the above problem, and it is not enough or careless that user lifts dynamics when in use
Etc. under reason, cause to fail valve rod lifting in place, so as to cause tap the problems such as dripping, flowing water occur, to have much room for improvement.
For above-mentioned technical problem, I is taken charge of research and development and the faucet valve core produced, water route is opened and closed in the form of pressing, is kept away
Exempt from that rotation/lifting dynamics is inadequate, negligent situation occurs, improved the utilization rate of water resource and with One In and Two Out
Using effect.
Utility model content
The purpose of this utility model is to provide a kind of new diverter valve spool, and this faucet valve core is opened and closed using pressing form
Water route and the using effect with One In and Two Out, therefrom overcome the shortcoming present in above-mentioned background technology.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of new shunt valve
Core, including upper valve body and the lower valve body that is threadedly coupled with upper valve body, the lower valve body include lower valve casing and in lower valve casings
The valve rod of stretching motion is done, the upper valve body includes the pressing mechanism that can be pressed valve rod；Set on the lower valve casing
There are the first water outlet, water inlet and the second water outlet for being interconnected and being sequentially distributed from top to bottom；One end of the valve rod
The first sealing ring is provided with, first sealing ring is inconsistent with the cavity in lower valve body and forms sealing surface, and described first is close
Seal ring can be obstructed the first water outlet, and the pressing mechanism can extrude valve rod and cause the positioned at valve rod one end
One sealing ring, which comes downwards to, is obstructed the second water outlet.
After above-mentioned technical proposal, when pressing mechanism is not subject to external force, the of valve rod lower end is now placed in
One sealing ring can be obstructed the first water outlet, it enters the water of spool by water inlet can only be from the second water outlet stream
Go out；When pressing mechanism is subject to external force and is in squeezed state, the power of the depressed mechanism of valve rod is come downwards to the second water outlet
Obstructed, the water that the first sealing ring positioned at valve rod lower end is passed to water inlet into spool can only be from the first water outlet
Outflow.By the above process, to reach the effect of One In and Two Out.Thus, by pressing repeatedly pressing mechanism repeatedly, can cut
Change control current water outlet direction.
The utility model is further arranged to：The upper valve body includes upper valve casing, and the upper valve casing is nested with pressing mechanism
Connect, the outer surface of the upper valve casing is provided with can be with the matched external screw thread of tap.
The utility model is further arranged to：The pressing mechanism includes pressing bar, rotation axis and spring, described to press bar
The double wedge for being externally provided with some circumference arrangements of bottom, one end of the rotation axis are equipped with some ratchets to cooperate with double wedge,
The rotation axis can be pressed in bar along the axial movement for pressing bar and being sheathed on, and the spring pocket is arranged in rotation axis, the bullet
The other end of spring is abutted against with lower valve body.
After above-mentioned technical proposal, double wedge is engaged with ratchet, and is pressed bar and promoted rotation axis to move down simultaneously
When compressing spring, double wedge can extrude ratchet, since contact area is smaller between double wedge and ratchet, thus cam and ratchet
Between pressure increase, moved down easy to rotation axis.
The utility model is further arranged to：The water inlet and the first water outlet are the waist type being arranged on lower valve casing
Hole, and set with the axisymmetrical of the lower valve casing, second water outlet is located at the bottom of lower valve casing.
The utility model is further arranged to：The upper valve casing is set with sealing ring, the upper valve in externally threaded side
Shell is fixedly connected with to limit the spacing ring of seal ring displacement close to the side of sealing ring.
After above-mentioned technical proposal, the positioning and sealing between spool and tap can be realized using sealing ring,
When avoiding with tap thread fitting, rotate excessively to cause to coordinate and fail.Sealing ring is between spacing ring and external screw thread so that close
The displacement of seal is limited, and then ensure that the sealing effect between sealing ring and tap.
The utility model is further arranged to：The valve rod includes the shift(ing) ring abutted against with spring, the shift(ing) ring
The gag lever post that can be socket-connected with spring is fixedly connected with axle center, the opposite side of the shift(ing) ring is provided with resetting spring, described
One end of resetting spring is abutted with lower valve shell phase, is fixedly connected with what can be socket-connected with resetting spring at the axle center of the shift(ing) ring
Valve portion.
After above-mentioned technical proposal, gag lever post can limit spring its displacement, avoid spring in use
Produce the phenomenon of dislocation.Valve portion can carry out resetting spring to limit its displacement, and valve portion can be done under ambient pressure in lower valve body
It is axially moved.
The utility model is further arranged to：Being equipped with the axle center of described upper valve casing one end can be matched with pressing mechanism
Passage, the top of the passage are axially arranged with the guide rail of some circumference arrangements along it, are arranged at intervals between the adjacent guide rail
