Abstract
A dual valve is composed of an orifice plate and a valve flap. Common water taps and the like have vulnerable parts and are easy to leak. Since a lot of water runs due to the repair without stopping pressing, the user cannot replace the water at any time, and a lot of resources are wasted. The utility model discloses set up the auxiliary valve of a no vulnerable part in the import department of main valve, it can be when the main valve needs to change the vulnerable part, lean on water pressure self-closing, in addition, the invention still has advantages such as with low costs, convenient to use, close reliably, convenient to maintain.
Description
The invention belongs to fluid control field.A kind of valve that constitutes by the orifice plate and the flap of valve.Known water tap is a use-case of this valve.Wherein, close the cushion of sealing usefulness between flap and the valve opening,, be easy to breakage and leak owing to often bear bigger pressure.Again owing to be difficult for stopping press changing, make the long-term seepage of many water taps and can not get timely improvement, cause bigger waste to water resources, the valve seepage in some fields also can cause environmental pollution and bigger harm.
The objective of the invention is to improve the structure of valve, valve is had when not stopping to depress the replacing easily damaged parts can not make fluid leak in a large number, and the maintenance that makes valve becomes easy, make valve often be in the works fine state of ne-leakage, to reach the purpose of administering the valve seepage, other harm that bring because of seepage have also been overcome.
For achieving the above object, the present invention has adopted following measure: it is characterized in that the orifice plate both sides between valve body snout cavity and outlet plenum respectively are provided with a flap, two flaps are linked to each other by a core bar; Wherein be positioned at the flap (being secondary flap) of snout cavity, on the end face of orifice plate, the conical surface or the sphere that can match with the taper hole of orifice plate arranged; Be positioned at the flap (being main valve) of outlet plenum, between the end face of orifice plate one side and orifice plate a cushion arranged, the other end of this flap has the helical thread portion that matches with the valve body screw, and stretches out the rod end that valve body is used for linking to each other with handle or control mechanism links to each other.Fig. 1 is the utility model structural representation.
The explanation of Fig. 1 drawing:
1, flap 2, valve body 3, cushion 4, flap 5, handle 6, rubber ring 7, orifice plate
One orifice plate 7 is arranged in embodiment's valve body 2, inner chamber is divided into a snout cavity and an outlet plenum, the flap 1 that is positioned at snout cavity is one radially to have the cylindric of window, it can with the concentric import in the hole of orifice plate 7 in do axial motion.Its external diameter is greater than the aperture of the restriction of orifice plate 7, the conical surface or sphere that it has on the end face of orifice plate 7 one sides the cone hole part branch with orifice plate 7 throttle orifices to match, it is under the effect of hydrodynamic pressure, and its bottom surface is crushed on flap 4 all the time and passes on the push rod (or core bar) of the throttle orifice of orifice plate 7; In the outlet plenum the outer end diameter of flap 4 greater than the restriction aperture of orifice plate 7, have one altogether between end face and the orifice plate 7 for the cushion 3 of closing sealing usefulness, the helical thread portion that its other end has the screw with valve body 2 to match and stretches out valve body and is used for the rod end that links to each other with handle.
By handle 5 with flap 4 when the direction that is screwed into the valve body screw is rotated, the end face that screw thread promotes flap 4 is pressed in cushion 3 on the orifice plate, fluid can't flow through the throttle orifice of sealed orifice plate 7, at this moment water tap is in closed condition.Certain opening makes valve be in open state, and flow is also along with the size of opening can be conditioned.
When oppositely twisting handle, the end face of flap 4 no longer is pressed in cushion 3 on the orifice plate 7, and makes the throttle orifice of orifice plate 7 certain opening occur, makes valve be in open state, and flow is also along with the size of opening the door can be conditioned.
Though flap 4 be in close or the regulation range of throttling in, its core bar makes flap 1 be in normally open all the time.
When need be at cushion 3 that press to change easily damaged parts or rubber ring 6, as long as oppositely twist handle 5, until flap is all withdrawed from from the screw of valve body 2, at this moment, the bottom surface of flap 1 along with push rod motion till on the taper hole that hydraulic pressure is pressed in the orifice plate restriction that matches with it with the cone or the sphere of flap 1 end face, flap 1 has begun closing function, thereby has effectively prevented the phenomenon that causes fluid to leak in a large number when flap 4 is removed.Make valve obtain and to have pressed the advantage of repairing.At this moment the flap 4 that will the change easily damaged parts valve body 2 of packing into, and twist until its push rod flap 1 is backed down, flap 4 recovers till the proper functioning, has just finished pressing more changing jobs.
The present invention has and can press the function of changing easily damaged parts, thereby makes valve often keep the works fine state of ne-leakage, has effectively protected resource.And overcome that ubiquitous valve is controlled problem leakage and the harm of the wasting of resources, environmental pollution and other aspect that cause because of seepage, have simple in structure, easy processing, easy to use, advantage such as the life-span is long in addition.
The present invention also can be applicable to make some the multiple throte valve of controlling effect Lou more by force, stop valve, pressure regulator valve, multiplex switch etc.
Claims (2)
1, a kind of dual valve comprises valve body, flap, handle, it is characterized in that respectively there is a flap orifice plate both sides between dual valve snout cavity and the outlet plenum, has a core bar to link to each other between the flap.
2, according to the described dual valve of claim, it is characterized in that being positioned at the flap of snout cavity on the end face of plate hole, one conical surface or the sphere that matches with the cone hole part branch of orifice plate 7 throttle orifices arranged, between the end face of plate hole and plate hole 7, a rubber ring 6 is arranged at the flap of outlet plenum, the other end of this flap has helical thread portion that the screw with valve body 2 matches and the rod end that stretches out valve body.
