Description
Technical field
The present invention relates to one-way valve, particularly relate to the combination brake switch and proporting combined by one-way valve.
Background technique
One-way valve is that fluid can only flow along water intake, and water outlet medium but cannot reflux, and is commonly called as one-way valve.One-way valve is also known as safety check or check valve.For preventing oil stream reverse flow in hydraulic system, or for preventing pressurized air reverse flow in pneumatic system.Existing one-way valve can only look at MEDIA FLOW to, can not the flow velocity of control media, more can not carry out self-control according to the size of medium amount, control the rate-of flow of water outlet, function singleness.And if use traffic valve replaces one-way valve, then cannot realize traffic organising, and the cost of Flow valve is higher, complex structure, is unfavorable for safeguarding.
Summary of the invention
The technical problem to be solved in the present invention is the defect that existing one-way valve and Flow valve all exist certain aspect, and providing a kind of can flow to and can control again the stable combination brake switch and proporting of the water supply of velocity of medium by control media for this reason.
Technological scheme of the present invention is: supply water stable combination brake switch and proporting, it comprises by intake pipe, transition conduit, the pipeline loop that L-type relief pipeline and drainage pipe are formed, described intake pipe ingress is hinged with the first one-way valve, described transition conduit and intake pipe vertical connection, described drainage pipe and transition conduit vertical connection, described drainage pipe end is hinged with the second one-way valve, described drainage pipe is communicated with L-type relief pipeline near the second one-way valve place plan vertical, the horizontal segment of described L-type relief pipeline is identical with intake pipe internal diameter, be mounted with between the horizontal segment of described L-type relief pipeline and intake pipe and left and right horizontal can move the pressure balance mechanism regulating flow rate of water flow.
Pressure balance mechanism described in such scheme comprises the piston suitable with the horizontal segment internal diameter of L-type relief pipeline, described piston is connected with plug by connecting rod, the internal diameter of the horizontal segment of described plug and intake pipe and L-type relief pipeline is suitable, and when piston moves left and right, plug can shutoff or open transition conduit.
The improvement of such scheme is that described connecting rod is divided into two sections, affixed by stage clip.
The further improvement of such scheme is that the horizontal segment inwall of described L-type relief pipeline is connected with the damp block that can stop piston movement near the bottom at drainage pipe place.
The longitudinal section of plug described in such scheme is fan-shaped.
The invention has the beneficial effects as follows and one-way valve and pipeline loop are organically combined by pressure balance mechanism, can carry out traffic organising to medium, can carry out flow control again to medium, structure is simple, and with low cost, it is convenient to safeguard.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
The present invention includes by intake pipe 1, transition conduit 2, the pipeline loop that L-type relief pipeline and drainage pipe 3 are formed, described intake pipe ingress is hinged with the first one-way valve 4, described transition conduit and intake pipe vertical connection, described drainage pipe and transition conduit vertical connection, described drainage pipe end is hinged with the second one-way valve 5, described drainage pipe is communicated with L-type relief pipeline near the second one-way valve place plan vertical, the horizontal segment 6 of described L-type relief pipeline is identical with intake pipe internal diameter, be mounted with between the horizontal segment of described L-type relief pipeline and intake pipe and left and right horizontal can move the pressure balance mechanism regulating flow rate of water flow.
Particularly, pressure balance mechanism can comprise the piston 7 suitable with the horizontal segment internal diameter of L-type relief pipeline, described piston is connected with plug 9 by connecting rod 8, the internal diameter of the horizontal segment of described plug and intake pipe and L-type relief pipeline is suitable, normality lower end cap is positioned at intake pipe, stops current to enter transition conduit from intake pipe.When piston moves left and right, plug can shutoff or open transition conduit.
A preference of the present invention is that connecting rod is formed by two sections, connected by stage clip 10 between two sections of connecting rods, stage clip plays pressure buffer effect, when intake pipe is intake, water impact plug makes plug be subject to horizontal thrust, stage clip compression is stressed, when current continue to enter intake pipe, the thrust of current is greater than the compressive force of stage clip, plug is made to get out of the way transition conduit to right translation, transition conduit is communicated with intake pipe, current enter transition conduit from intake pipe, current are larger, the thrust that plug is subject to is larger, when thrust is large to a certain degree promoting piston to right translation, transition conduit is communicated with intake pipe completely, current enter drainage pipe, discharged by the second one-way valve.When water flow continues to increase, current can not be discharged by the water displacement of the second one-way valve in time, vertical section 12 by L-type relief pipeline enters by current, thrust is left provided to the piston in the horizontal segment of L-type relief pipeline, when this burst thrust is left greater than the thrust to the right that plug is subject to, piston is moved to the left, drive plug is moved to the left, transition conduit will by part shutoff, the water flow flowing into transition conduit from intake pipe reduces, the water flow entering L-type relief pipeline reduces, piston thrust is left reduced, piston Easy abeadl, until the piston thrust be subject to left to equal the thrust that plug is subject to the right equal, piston rest is motionless, after the water flow of intake pipe inflow transition conduit reduces further, current dam by plug by the connectivity part blocking intake pipe and transition conduit completely, complete a work cycle.Water flow during this in drainage pipe maintains in a stable scope all the time, ensures that the water flow of discharging from the second one-way valve can not exceed the design water yield.
In order to ensure that piston can not push against the horizontal segment of L-type relief pipeline and the inwall of vertical section transition position when moving right, cause piston can not be moved to the left by water jet propulsion, preferably be connected with the damp block 11 that can stop piston movement near the bottom at drainage pipe place at the horizontal segment inwall of L-type relief pipeline, the size of damp block would not affect the active force of current to piston, that is damp block will be far smaller than piston, as long as can play spacing effect.Distance between damp block and piston will be not less than the distance between normality lower end cap and L-type relief pipeline, can transition conduit be made completely open-minded when pressure balance mechanism moves right.
In order to eliminate water hammer, the longitudinal section of plug is preferably in fan-shaped, so the current entered can provide the thrust left of a stable equilibrium to plug, two carry out plug can rive when being moved to the left current, reduces the current of backflow to the impact force of the first one-way valve.
The indicative explaination that " left side " and " right side " mentioned in the present invention is just made relative to accompanying drawing 1, should not be construed as limitation of the present invention.The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
