Abstract
The invention discloses a spherical automatic switching check valve. The spherical automatic switching check valve comprises an upper valve body (1) and a lower valve body (2) which are connected with each other, wherein a discharge channel (11) is arranged on the upper valve body (1); two feed channels (21) are arranged on the lower valve body (2); a sealing ball (3) for sealing the feed channels (21) is arranged in a valve body cavity; and the spherical automatic switching check valve can be used for automatically switching the ore pulp conveying direction during operation of a slurry pump. By the spherical automatic switching check valve, a process step of manually controlling the ore pulp flowing direction is not needed, manpower is saved, and operation is facilitated, so that the operation of a whole process system is more reliable.
Description
Technical field
The invention belongs to field of check valves, relate in particular to a kind of spherical automatic switchover safety check.
Background technique
Factory, water treatment plant, large-scale lubrication system etc. locate often to use safety check in all kinds of ore deposit; Conventional check valves adopts the steel manufacturing, has only an import and an outlet, and wearing and tearing are violent in the using process; And has only a flow direction; When needs change the ore pulp flow direction, need artificial adjustment, bothersome effort.
Summary of the invention
Have only a passage to general check valve, switch the defective of ore pulp flow direction operation effort, technical problem to be solved by this invention provides a kind of slurries and switches spherical rapidly automatic switchover safety check.
In order to solve the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of spherical automatic switchover safety check comprises upper valve body and following valve body; Upper valve body links to each other with following valve body, and upper valve body is provided with tapping channel, and following valve body is provided with feeding-passage; Feeding-passage has two, between two feeding-passages an angle is arranged, and also comprises ball sealer; Ball sealer is positioned at valve pocket, and ball sealer adopts ball or steel ball, and upper valve body is provided with the slideway cavity that can supply ball sealer movable; The two ends of slideway cavity are respectively equipped with a guiding voussoir, and the slideway cavity is communicated with tapping channel, and the ball sealer diameter is greater than the inlet passage diameter.Upper valve body is provided with wearing layer with following valve interior wall.Wearing layer uses reaction silicon carbide or abrasive rubber, and to increase the service life: when being used for all kinds of chemical industry or water treatment plant, this part is processed by stainless steel or inwall and valve body are lined with the wear-and corrosion-resistant material; When being used for big flow lubrication system, inwall or valve body are lined with oil resisting materials such as oil resistant rubber or polyurethane.The upper valve body end is provided with the upper valve body flange, and following valve end is provided with down valve flange, and the upper valve body flange is square or circular with following valve flange, connects for bolt between upper valve body flange and the following valve flange.The slideway cavity is a hemisphere.The tapping channel end is provided with the tapping channel flange, and the feeding-passage end is provided with the feeding-passage flange.When these parts are used for ore dressing plant and ore pulp transfer line, can be in slag stock pump operation process, automatic switchover ore pulp throughput direction.Thereby save manually operated ore pulp flow direction operation, save manpower, easy-to-operat, thus make whole process system operation more reliable.
Working procedure is: feeding-passage is connected with the delivery outlet of slag stock pump, and tapping channel is an output terminal, is connected with system pipeline.When with pump work that a feeding-passage links to each other; Ore pulp pressure (being generally about 0.5MPa) backs down ball sealer; Ball sealer is being shifted under the restriction of slideway cavity on another feeding-passage automatically; The sealing ball leans on the pressure of ore pulp closely to contact with the feeding-passage opening, thereby realizes good sealing, and ore pulp is carried in system by a tapping channel; When the slag stock pump of another feeding-passage end of technological requirement is worked; The slag stock pump of former feeding-passage end quits work and pressure release; The slag stock pump of the other end is opened, and then ball sealer is shifted to former feeding-passage under the effect of ore pulp pressure; Former feeding-passage sealing this moment, ore pulp is got into by another feeding-passage and flows to tapping channel.
The invention has the advantages that, can not cause the alluvial of solid matter in the slurries, advantages such as easy to operate smooth and easy during switchable pump, this valve has that slurries switch rapidly, good airproof performance, wear resistance are strong, long service life.
