Abstract
The utility model discloses a spherical auto-switching check valve which comprises an upper valve body (1) and a lower valve body (2), which are connected with each other. The upper valve body (1) is provided with a discharging passage (11), the lower valve body (2) is provided with two feeding passages (21), a valve cavity is provided with a sealing ball (3) for sealing the feeding passages (21), and slurry delivery direction can be automatically switched by the check valve in operation process of a slurry pump. Therefore, manual control of slurry flowing process is omitted, manpower is saved, the check valve is convenient to operate, and a whole process system operates more reliably.
Description
Technical field
The utility model belongs to field of check valves, relates in particular to a kind of spherical automatic switchover safety check.
Background technique
Locate often to use safety check in all kinds of ore deposit factory, water treatment plant, large-scale lubrication system etc., conventional check valves adopts the steel manufacturing, only have an import and an outlet, wearing and tearing are violent in the using process, and only has a flow direction, when needs change the ore pulp flow direction, need manually to adjust bothersome effort.
The model utility content
Only have a passage for general check valve, switch the defective of the mobile direction operation effort of ore pulp, technical problem to be solved in the utility model provides a kind of slurries and switches rapidly spherical automatic switchover safety check.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of spherical automatic switchover safety check, comprise upper valve body and lower valve body, upper valve body links to each other with lower valve body, upper valve body is provided with tapping channel, lower 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, ball sealer adopts ball or steel ball, and upper valve body is provided with can be for the slideway cavity of ball sealer activity, and the two ends of slideway cavity are respectively equipped with a guiding voussoir, the slideway cavity is communicated with tapping channel, and the ball sealer diameter is greater than the inlet passage diameter.Upper valve body and lower valve interior wall are provided with wearing layer.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 made by stainless steel or inwall and valve body are lined with wear-resistant anticorrosive material; When being used for large flow lubrication system, inwall or valve body are lined with the oil resisting materials such as oil resistant rubber or polyurethane.The upper valve body end is provided with the upper valve body flange, and lower valve end is provided with lower valve flange, and upper valve body flange and lower valve flange are square or circular, connects for bolt between upper valve body flange and the lower valve flange.The slideway cavity is 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 pulp conveying pipeline, can be in slag stock pump operation process, automatic switchover pulp conveying 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 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 at automatic moving under the restriction of slideway cavity on another feeding-passage, the sealing ball is by pressure and the feeding-passage opening close contact of ore pulp, thereby realize 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, then ball sealer is under the ore pulp pressure-acting, shift to former feeding-passage, former feeding-passage sealing this moment, ore pulp is entered by another feeding-passage and flows to tapping channel.
The utility model has the advantage of, can not cause the alluvial of solid matter in the slurries, the 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.
