Abstract

The invention relates to a three-chamber unidirectional check valve which is suitable for cleaning a fluid facility and a pipeline and called as 'flow information valve'. The valve can not adjust or control fluid, but reflects the state flow which flows through the valve with in the way of information by a valve core which consists of a shunt structure and an information display mechanism; the user can directly observe or obtains the state flow information of the fluid by an output element. The state flow information is similar to an instant state flux which is displayed by a flow meter, which hides the working and technical conditions of the facilities and the pipelines behind the valve; two technical conditions of a leakage malfunction or a full injection state of the facilities and the pipelines behind the valve can be monitored according to the information which is generated in the state flux change process. The valve is required to be arranged at a unit beginning position which is formed by the facility and the pipeline; the information which is generated under the match of other control devices has the definition of leakage or full injection. The valve has the advantages that the application is not restricted, and the installation and application are convenient.

Description

Flux information valve

Technical field

The present invention relates to the valve that a kind of suitable cleaning fluid facility and pipeline are used for technical monitoring, reflect the state flow information that fluid occurs when flowing through valve by having the rise-fall type spool that shunting is constructed and information institution is formed, information can observe or be exported by element by the information cover on the valve body.

This valve need be installed in the starting point place, unit of a facility and institute's metal conduit, can be from state flow information monitoring to valve after the unit whether " leakage " fault appears; Monitor container and " filling with " state whether occurs.

Background technique

In the prior art, the most common, most widely used fluid metering instrument is water meter and gas meter.City tap-water many residents that Every household has an ammeter realize that by observing practice the digital consumption that shows of state flow-rate ratio of water meter is even more important; Because of its state flow is implying the facility after the instrument and work, the technology status of pipeline.The solar water heater that is installed on the roof is the facility of least convenient contact and management, and the user just monitors by the state flow of observing water meter.Method is with other water valve closing of this family, observes the state flow that flows into solar water heater separately, when the water meter rotating disk by fast slack-off to stopping then to represent that water " fills with ", working properly; If rotating disk can not stop, then " leakage " appears in expression.Another kind method is moving and find that " leakage " occurred by the not stall of water meter rotating disk, then the feed-water valve of these whole facilities in family is closed, open the back and observe at one place, a place again, and rotating disk can not stop behind certain valve opening, and the facility that then is judged to be behind this valve breaks down.Therefore, building resident family will remove to observe water meter when being everlasting through the Stall meter box, and some children also can.In a word, utilizing water meter to monitor this family drainage facility, be very more convenient than the observation of last roof to solar water heater, but upstairs resident family need remove to observe water meter to Stall, feels another kind of inconvenient again.Because of water meter belongs to the measuring apparatus that water-supplying unit supervises, be at will to move, install and use the family to obtain conveniently.

Summary of the invention

The invention provides a kind of unidirectional valve that passes through of cleaning fluid that is applicable to.This valve convection cell can not be controlled and adjust, but will reflect with stastus format by the flow of valve fluid, is shown or output by information institution, and the user uses the technology status of pipeline and facility behind this information monitoring valve.The flow of its information performance is the comparative quantity of stastus format, so be called " state flow ", the indignant thought of " fast, slow " expression flow " large and small " of similar water meter rotating disk.Because the form of the composition is similar to safety check with installation method, so be named " flux information valve "; Now still have the non-return effect, use but can not work as safety check.

The present invention solve technological scheme that its technical problem takes be utilize Lift check valve fluid by the time, the lift that spool produces with changes in flow rate is as flow information; One covering device is set this information is shown or transmits for user's use be its basic scheme.But the information that the former spool of safety check produces when flow is small is extremely not obvious so that be difficult to perceive, and the spool dividing technology scheme that this valve adopts is with this information tangible dominant alternative that becomes.

Concrete scheme is: a kind of three chamber one-way cocks that the rise-fall type spool is housed, comprise: a valve body (1), an information cover (13), a spool (6), a piston barrel (9) and information piston, a pilot sleeve (18) and damping tray (19), a seal ring (8), a spring (2), ball valve (4) and ball valve bar (7) is characterized in that: described valve has snout cavity (A), shunting chamber (B) and three chambers of outlet plenum (C); Piston barrel (9) and information piston are used to reflect the state flow information that occurs when fluid flows through valve, and this information is directly shown by information institution or exports through element; Valve also is provided with and prevents the automatic sealing device that fluid leaks when information cover (13) accidental damage.

The valve body improvement project mainly is to set up an information cover on top, and the information that allows spool produce here shows or exports.Scheme one: the information cover that is used for observed information adopts the transparent material manufacturing; Scheme two: be used for the available transparent material of information cover or the metallic material manufacturing of output information, need at top configuration information sense cell mounting hole.

Adopting the spool dividing technology to make the tangible scheme of tiny flow quantity is at center spool tap hole to be set, and tap hole top configuration information piston mechanism promotes piston with shunting and shows information.Information displaying scheme one: one group of piston is set in piston barrel, one of them center piston, a plurality of shell type pistons of overcoat, shape such as telescopic fishing rod show different shunt volumes with the different-diameter piston; Being characterized in that the metering-orifice on barrel wall and the shell type piston wall is located at sustained height, making piston show that the information lift is identical, help touching sense cell, is to be " basic model ".Information displaying scheme two: a piston only is set in piston barrel, and different heights is established metering orifice and is made piston by different flow rising demonstration information on barrel wall, and the usefulness of seemingly going fishing upright floats the sample lifting and show information, for direct observation usefulness, is to be " simple type ".Scheme three: establish be " output type " that output element is installed in the hole at " basic model " information cover top.

More obvious for big flow information demonstration, to set up sliding barrel in rise-fall type spool bottom, and establish flowing hole in cylindrical shell bottom, spool must raise one apart from just overcurrent occurring, and this is apart from the appearance that has shown big flow.Also set up a damping tray at spool top certain position, the cylindrical shell of setting up with the pilot sleeve on the valve body forms a cover damping device, makes the spool lifting comparatively steady.Damping tray simultaneously flows out part to the shunting of valve body top and is separated out one and shunts the chamber, makes this valve just have import, shunting and exports three chambers.

Transparent material at present commonly used mostly is fragility, the damage that may meet accident during with this made use of information cover.Cause escape of liquid for avoiding meeting accident damaging, be provided with two kinds of automatic locking devices in the valve: in the tap hole bottom one ball valve is set, an attached ball valve bar penetrates in the center piston hole, meets accident when damaging, and drives ball valve by center piston and seals tap hole automatically; Circle is provided with a seal ring with the piston barrel binding site in the damping tray upper end, with the automatic sealing device of the chamfer formation spool rising limit under the pilot sleeve.

Because " flux information valve " is the device as the technology status of facility and pipeline behind the monitoring valve, must set the mounting point by the monitoring purpose, the information of its generation meaning that just possesses skills.As monitoring during " leakages " fault, be installed in a facility and under the fluid input place of pipe special unit, the flow information of " flow is arranged ", then expression appearance " leakage " also appear after this unit fluid outlet valve Close All.As monitoring " filling with " state, for non-enclosed liquid container, must be installed in the The initial segment of special-purpose flow in pipes, when the liquid level restricting means on the container was closed liquid stream, " no flow " that " flux information valve " shows was " filling with " information; For the closed gas container, the preceding source of the gas outlet of " flux information valve " flow in pipes to be installed regulator must be set, its delivery pressure meets the container allowable pressure and can inject, and injects flow information and then represents " filling with " for " no flow ".

Because the state flow of the similar flowmeter of state flow information that " flux information valve " produces, be installed in the function that special position has facility and pipe technology situation behind the similar flow instrument reflection table, but it does not belong to the measuring apparatus of being supervised; Therefore, the user can be installed in and think and need to use on the facility of monitoring and the pipeline, can be installed in the position that most convenient obtains information.It is simple that this valve has principle, easy to manufacture, and the easy-to-install characteristics can extensively be used, and is suitable for the user installation utilization of civilian tap water and gas ductwork especially.

Embodiment

Below in conjunction with description of drawings the invention process example;

Fig. 1 is the basic structure sectional view of " flux information valve ", wherein: 1-valve body, 2-spring, 3-filter screen, 4-ball valve, 5-shunts orifice plate, 6-spool, 7-ball valve bar, 8-seal ring, the 9-piston barrel, 10-metering-orifice, 11-center piston, 12-hat type counterweight, 13-information cover, 14-back-up ring, 15-shell type piston, 16-sealing gasket, the 17-nut, 18-pilot sleeve, 19-damping tray, 20-counterweight, the 21-flowing hole, the A-snout cavity, B-shunts chamber, C-outlet plenum.

Fig. 1 is designed to the internal thread mode of connection, and view is a Product Status.Increasing a vertical inlet in the bottom during valve body 1 design selects for the user; The information piston material is elected plastics as, appearance is filled in colors on a sketch: center piston 11 is for yellow, minor diameter shell type piston in the shell type piston 15 is orange, major diameter shell type piston is red, each piston all is equipped with corresponding counterweight, when dependable flow was ascending, piston rose to by center piston 11 and begins to minor diameter, to the order of major diameter shell type piston 15; Piston barrel 9 is blue.The ball valve 4 of shunting orifice plate 5 belows has corresponding weight, makes the spring 2 compression relief ball valves 4 that are installed in the filter screen 3 produce certain interval with tap hole, keeps shunting unimpeded.Ball valve bar 7 upper ends are threaded in center piston 11 holes.Damping tray 19 positions form a big gap with the cylindrical shell lower end surface outside pilot sleeve 18 cylindrical shells, enough allow maximum shunt pass through; Damping tray 19 sides enter cylindrical shell and form damping device when spool 6 raises, and its gap should not be too little.The information cover 13 of transparent material manufacturing can be established equidistant horizontal line scale at the cover inwall, and the interior air of cover is compressed when being used for liquid, and liquid level is just represented the size state of hydraulic pressure.

" flux information valve " that Fig. 2 installs for level, vertical inlet is sealed, is in no flow status, and piston and spool are taken a seat by deadweight.

The view of Fig. 3 is small minute stream mode, and spool 6 is taken a seat and closed.Fluid advances tap hole through filter screen 3, center piston 11 is promoted upwards and above metering-orifice 10 on shell type piston 15 walls, flowed into by metering-orifice then and shunt chamber B, flow to outlet plenum C by the big gap of damping device again.Center piston 11 raises and has finished the procedure for displaying of small diffluent information.

The view that Fig. 4 increases for shunting.Small bore piston cinclides in the shell type piston 15 does not hold bigger shunting, is then promoted upwards above metering-orifice on the enlarged bore piston wall in the shell type piston 15, outflow then by shunting.The procedure for displaying than large shunt information has been finished in small bore piston rising in the shell type piston 15.

Fig. 5 promotes the process view of the enlarged bore piston rising demonstration large shunt information in the shell type piston 15 for large shunt; With Fig. 3, Fig. 4 similar process.

Fig. 6 continues to increase for flow, and metering-orifice 10 does not hold on piston barrel 9 walls, just promotes distance of spool 6 risings, and the flowing hole 21 on the spool cylindrical shell rises up into outlet plenum C, and fluid just flows directly into outlet plenum C from snout cavity A.Piston barrel 9 also raises simultaneously and has shown big flow information.Damping tray 19 also enters simultaneously and forms damping device in the pilot sleeve 18.

When flow from large to small, spool 6 relies on deadweight at first to take a seat and closes, and transfers to and large shunt information occurs; Flow diminishes again, transfers big flow information to tiny flow quantity information.Its process and order are ascending opposite with flow.When the shunting disappearance, center piston 11 also falls.

Fig. 7 represents that transparent information cover 13 splits when quick-fried, shunting chamber B loses pressure, snout cavity A and outlet plenum C internal pressure flow out common propelling fluid outside the information cover 13, moment flow spool 6 is raised to limit position, seal ring 8 is pressed on 18 times chamfers of pilot sleeve and stops fluid; Moment, flow desired the full detail piston is released layer by layer simultaneously, in the middle of the plug 11 of being indecisive and changeable raise and exceed stroke and just drive ball valve bar 7 and drag ball valve 4 and close shunting orifice plates 5, stop fluid.After these two kinds of automatic sealing device block fluid, snout cavity A is communicated with outlet plenum C, and information institution is ineffective.

Fig. 8 is " simple type flux information valve " the structure sectional view that is threaded, and its information piston only is provided with one, and the metering-orifice on the piston cylinder body wall is arranged on different heights, following little going up greatly; Little big the outflow also pressed in shunting, promotes piston and presses the little big segmentation demonstration flow information of.The piston rod appearance of demonstration information is filled in colors on a sketch segmentation corresponding to the metering-orifice distance.Other structure is identical with " basic model ".

" the output type flux information valve " that Fig. 9 links for flange, structural form is identical with " basic model ", and difference is at information cover top the information output element to be installed.The information cover can make the metallic material manufacturing on demand into.

Figure 11 is the scheme of installation of domestic gas terminal equipment with " flux information valve " monitoring " leakage " fault.The daily gas time of resident resident family is several hrs only, and each arm is sentenced equipment of one " valve " monitoring behind gas meter, and the position that can select to be installed in the optimum observation makes things convenient for the user to monitor often.

Figure 12 is the scheme of installations of three building resident families with " flux information valve " monitoring roof solar water heater and sanitary equipment " leakage " fault and " filling with " situation.Be installed in the building as figure, resident family does not just spend and observes water meter downstairs.

Figure 14 is " flux information valve " mounting point schematic representation of the head-tank far away that supplies water with pressure or water pump.At the section start that water pipe is convenient to control this valve is installed, when head-tank " was filled with ", float valve was closed flow is subtracted

Little of stopping, this valve will show the information of changes in flow rate, prompting user control.This valve is installed can be saved traditional by the information feedback device of pond to the control position.

Figure 15 is a seal container when injecting pressurized gas, and with the mounting point schematic representation that " flux information valve " monitoring " is filled with ", tyre inflation is the most general among the figure.At present, the operator is usually with the experience estimation gas amount of charging into, and uses the pressure gauge inspection after cutting off source of the gas, and the pressure criterion that exceeds standard is emitted, and underpressure is then filled again, repeatedly can meet standard repeatedly.The barometric control unit of one similar oxygen regulating valve is set at the source of the gas outlet pipe section when using this valve unit monitoring inflation, earlier pressure is adjusted to the standard pressure of tire, " filling with " information of observing this valve during inflation can once be finished.This valve has the function that detection has a flat tire simultaneously.

Figure 11, Figure 12, Figure 14 and four kinds of operational modes of Figure 15 show that " flux information valve " installation is simple, extensively are suitable for.Manufactory need not increase input and just can manufacture and design its series product according to fluid properties and function of use.
