Abstract
The utility model provides a multifunctional controllable one-way sample taking throttling ball valve. The International Classification of the ball valve is F16K15/04, and the dimension of external shape conforms to the standard of the ball valve of nation-machine department JB1683-75 and JB1744-75. A valve gate has miscellaneous functions of a one-way valve, a controllable one-way valve, a sample taking valve, a throttling valve, a stop valve, etc., and the valve gate can use a single function and combine multi-functions for use. The utility model has the advantages of various control forms and high universality, being able to be made of various materials. The newly designed forming die adopts a haf-face vertical to a rotating shaft central plane.
Description
The present invention is a kind of advanced person, by the multiduty valve that several single function valves combine, need to be specially adapted to the pipe-line system of multiple function.Past does not all have identical multi-functional valve both at home and abroad and occurs, and the International Classification of Patents of ball valve valve is F16K15/04
Existing general valve is a simple function mostly, is installed in to have only a kind of purposes in the pipeline, under some occasion, the installation complexity of equipment, the also corresponding raising of cost, makes troubles for the maintenance of equipment.Multi-functional controlled unidirectional-sampling-throttling-ball valve plays the effect of multi-purpose valve.It installs controlled unidirectional non-return spool based on ball valve at an end of ball valve, the one-way valve that can make this valve play one-way valve and can discharge.This unidirectional non-return spool can be installed and used separately, also can install and use simultaneously with controlled single-direction balls core, when fitting together, can play the double action of unidirectional check valve and stop valve simultaneously.In addition, this valve has added a small needle valve or membrane valve in the stage casing of valve body, to make the usefulness of sampling.Generally speaking, sampling cock does not wish that a large amount of liquid goes out particularly corrosive liquid when opening sampling.This valve can meet this requirement.The sampling valve seat of this valve, it is the characteristic of utilizing ball core contract fully and the logical position of standard-sized sheet two end fluids can be cut off, the liquid that intermediate section retains, can not have pressure or low pressure, flow out by the sampling cock outlet naturally, thereby reach the purpose of safety sampling, and more simple in structure than common sampling cock, cost is low, and is effective.
The external dimension of this valve are identical with the standard of domestic First Machinery Industry Department spherical valve, so highly versatile, easy for installation.This valve design uniqueness can be accomplished multi-purpose valve, has the function of two or more single function valve simultaneously concurrently, can play stop valve, throttle valve, one-way valve, controllable check valve, five kinds of functions of sampling cock.The switch activated mode of operation of this valve also has manually, surges, various ways such as pneumatic, electronic.According to the difference of using object, the material of this valve can be selected raw material such as glass fibre reinforced plastics, tetrafluoroethylene, cast iron, cast steel, stainless steel, alloyed steel or reinforced plastic for use.
Accompanying drawing is a concrete structure of the present invention.
The compressing employing thermosetting closed pressing die of fiberglass valve body. In this type of process of producing product of past, for solving the dismounting of rotating shaft base side core. The consistent method that adopts mould Hough face to coincide with the turning cylinder central plane, though can solve like this dismounting of side core, but because the position of Hough face is unreasonable, caused mould structure complexity and processing difficulties, mould and die accuracy and compacted products quality have all been brought very big impact.
Newly-designed mould adopts the Hough face perpendicular to the turning cylinder central plane, side core with loose core and valve body in the method for unloading, the shaping that had both solved valve body is again so that mould structure obtains significant improvement and simplification. The vertical precision in side core hole obviously improves, and clamp for machining easy so that the processing advantage of large diameter valve mould is particularly outstanding is for a new road has been started in the processing of large bore valves.
In old product, rotatingshaft Hough face place is provided with a stiffening rib for strengthening with leakproof, but actual effect is run counter to desire, because the glass fibre reinforced plastics raw material is obstructed in side core place curtain coating in pressing process, cause stiffening rib to lack material, the tissue pine is dredged, and becomes the main breakthrough of valve body.
In the new die design, this stiffening rib has been cancelled in resetting of Hough face, and tissue compacting herein is tight, thereby has solved the difficult problem of valve body seepage.
Novel die is not only reasonable in design, and process easy, guaranteed mould precision and prolonged working life, make the compacted products quality improve greatly.The percentage of A-class goods rises, and has saved raw material, remarkable benefit.
This valve is equipped with the ball core (6) of controlled unidirectional and throttling function by be main body with valve body (1) more than one in the valve body, a pressure ring hold concurrently one-way valve seat (7) and rotatingshaft (3), the one-way valve double trim ring (10) that leads can constitute an ordinary ball valve.One end of the valve body controllable check valve core (8) of can packing into, then valve has the double action of unidirectional non-return and stop valve.The sampling valve seat (11) of can packing in the stage casing of valve body starts the switch swing handle (12) of sampling valve seat, just can obtain fluid sample safely under the situation of not having pressure or low pressure.
