Abstract

The utility model relates to a reversal valve, which comprises a valve body, a valve cap, a valve core, a valve lever, a handwheel, etc.; the utility model is characterized in that four inlet / outlet are arranged on the valve body of the valve; four grooves having different slope angles are arranged at the surface of the valve and the valve core cylinder; according to the alternate position of the valve core, each arc groove can be connected with different outlet; the position of the valve core is rotated, and the reversing valve of the fluid reversing is realized. The utility model can be used for the conveying system of liquid of the industrial water, oil, sour, alkalis and salt of the chemical industry, the oilfield, the dynamic force, etc.; multi-valve can be replaced by only one valve.

Description

Manual Hydraulic switch stand

The invention belongs to valve type.

In the production process of industry such as oil, chemical industry, power, often run into the fluid that is transferred and to change its flow direction every now and then.This all is to adorn four common shutoff valves in general pipe-line system, and by two valves open, two valves close the change that realizes its fluid flow direction.The shortcoming of this method is many, the troublesome poeration of valve, and causes the accident and easily misoperation takes place in the operating process.

Be simplified system, easy-to-operat, the present invention makes in pipe-line system according to a kind of Manual Hydraulic switch stand of two threeway principle design, only needs a this valve is installed, and just can be in operation changes the flow direction of fluid easily.The same with common valve, this invention change-over valve also is made up of parts such as valve body, spool, valve rod, handles.Fig. 1,2 is the two sides figure of valve body, and valve body 5 of the present invention as shown in the figure has the valve core chamber 6 of a cylinder type, and an outlet 1,2 is respectively arranged about valve core chamber, communicates with feed liquor and fluid pipe-line system respectively.The front and back of valve core chamber are at the different level place, generally can more than valve core chamber's center absolute altitude or below, an outlet 3,4 is respectively arranged, connect the import and export of using liquid plant respectively.Importing and exporting roundedly has flange spool or screw thread pipe nipple to link to each other with system.Fig. 3, the 4th, the two sides figure of spool, valve has a cylindrical spool 7, have four camber conduits one, two, three, four that are different angle on the periphery of spool, pack into the valve core chamber of cylinder type of spool, the internal surface of this camber conduit and garden column type valve core chamber is formed the fluid passage of four different angle.Rectangular or the lower-circle-square-shape in the cross section of conduit, area is determined according to the flow size.Four groove two two-phases on the spool be compiled in valve core chamber about import and export 1,2, but to not communicating.According to the diverse location of spool in valve core chamber, make in two pairs of camber passages, can be respectively communicate with two gateways 3,4 of different level before and after the valve core chamber.Spool roof anchorage one valve rod 8, it is operated valve that the position that handle is used for adjusting spool is housed on the valve rod.One fixed pointers is arranged at valve rod top, and a dial is arranged on the valve cover, is carved with 0 °, 90 °, 180 °, 270 ° scales, can be used to indicate the working position of valve.Bigger valve, the spool of its garden column type can be made hollow, to save material.During use, when valve is in the position 1. the time, passage one is communicated with 1,4 holes, and passage four connects 3,2 holes, and fluid flow is 1 → 4 → equipment → 3 → 2.Spool Rotate 180 °, be in the position 2. the time, passage two is connected 1,3 holes, passage three is connected 2,4 holes, fluid flow becomes 1 → 3 → equipment → 4 → 2, spool Rotate 180 ° like this, and the flow direction by equipment becomes by 3 → 4 by 4 → 3, realized fluid diverting, spool half-twist valve place closed condition.

Advantage of the present invention is to simplify system, replaces the function of several valves with a valve.Under running situation, realize the change of flow direction easily, and flexible and convenient operation, only need direction of valve core rotation just can be finished once-through operation, easily realize operation automation.

The present invention can be widely used in the transporting system of liquid such as water, oil, acid, alkali, in order to change the flow direction of carrying liquid.

Claims

1, a kind of valve that constitutes by critical pieces such as valve body, valve cover, spool, valve rod, handles, it is characterized in that said valve body 5 has a cylinder type valve core chamber 6, valve core chamber has four to import and export 1,2,3,4, can be connected with the equipment that uses liquid with liquid system respectively.Said spool is cylindrical, has the groove such as the figure one, two, three, four of four different angle on its periphery.Spool is loaded in the cylinder type valve core chamber of valve body, and curved channel and valve core chamber's internal surface are formed fluid path, according to the diverse location of spool in valve core chamber, every curved channel can be communicated with two different import and export.

2, by the described valve body of claim 1 four import and export are arranged, two 1,2 link to each other with the liquid in-out system about it, at same horizontal absolute altitude.Former and later two are imported and exported 3,4 and are connected with the equipment of use liquid, and two holes are at same horizontal absolute altitude, one more than valve core chamber's central horizontal absolute altitude, one below valve core chamber's central horizontal absolute altitude.Import and export roundedly, have flange or screw thread pipe nipple to link to each other with system.

3, by the described valve spool of claim 1, have the conduit of four different angle on its barrel surface, conduit two two-phases are converged, pack into the valve core chamber of valve body of spool, two intersections just communicate with the import and export 1,2 of system's feed liquor and fluid.The other end of conduit communicates with the hole 3,4 of using liquid plant to link to each other respectively at valve core chamber.The section of conduit can be rectangle or half garden rectangle, and the minor valve spool is solid, and large-scale valve can be made hollow.

4, by on the described valve door closure of claim 1 dial being arranged, scale is 0 °, 90 °, 180 °, 270 °.Pointer is arranged on the valve rod, be used to refer to the working position of valve.
