Abstract
The utility model discloses a check valve of a slurry pump. The check valve comprises a valve body, a taper valve cover, a valve element shaft, blades with tilted angles and a cleaning opening. A feed port is formed in the bottom of the valve body, a lower flange is connected to the bottom of the valve body, a discharge port is located at the top of the valve body, an upper flange is connected to the top of the valve body, the taper valve cover is fixed onto the valve element shaft, the valve element shaft can move up and down so as to open or close the valve, the blades with the tilted angles are arranged at the upper end of the taper valve cover (on the valve element shaft), the blades with the tilted angles are fixed onto the valve element shaft and can drive the valve element shaft to rotate, the valve element shaft is provided with an upper shaft sleeve and a lower shaft sleeve, the valve element shaft is supported through a supporting rib, the cleaning opening is formed in one side of the valve body and connected with a screw cap, and a screw handle is connected to the screw cap. The check valve of the slurry pump can effectively prevent equipment from being damaged by slurry backflow, the situation that the valve is struck to fail can be avoided to the maximum extent; when emergency situations occur, the valve body can be opened conveniently and rapidly for cleaning, and production requirements are met.
Description
Technical field
The utility model relates to a kind of ore slurry pump safety check, belongs to mine, ore operation supplementary equipment field.
Background technique
Mine, ore processing factory, need frequent transfer ore pulp, when the prominent chance of various ore slurry pumps fault stops or stopping voluntarily in the past, ore pulp can turn back in pump along going out pipe, the recoil force that ore pulp returns can cause pump impeller reversion, equipment is caused to damage, thus be starved of safety check prevent ore pulp flow backwards.
Patent < < ore slurry pump safety check > > (application number 201220110261.5) discloses a kind of safety check, this safety check can effectively prevent that ore pulp from flowing backwards, but this valve runs into while having compared with ratchel or other impurity, easily malfunctioning stuck, clear up also very inconvenient, so, also often affecting production operation, can not meet the needs of production.
Model utility content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of stuck, easy cleaning simple in structure, not easy to failure and practical ore slurry pump safety check are provided.
For overcoming the deficiencies in the prior art, the utility model is taked following technological scheme:
A kind of ore slurry pump safety check, comprise valve body, tapering valve gap, poppet shaft, blade with angle and clean-up port, it is characterized in that: material entrance is positioned at the bottom of valve body, valve body bottom is connected with lower flange, discharge port is positioned at the top of valve body, valve body top is connected with upper flange, tapering valve gap is fixed in poppet shaft, poppet shaft can up and downly be opened or throttle down with this, tapered valve covers end (in poppet shaft) multi-disc blade with angle, blade with angle is fixed in poppet shaft and can drives poppet shaft rotation, in poppet shaft, there are upper and lower two axle sleeves, poppet shaft supports with supporting rib, one side of valve body has clean-up port, clean-up port is connected with spiral cover, on spiral cover, be connected with and revolve hand.
During ore slurry pump work, by ore slurry pump, drive ore pulp that tapering valve gap is washed open, make safety check in open mode, meanwhile, under the driving of ore pulp, blade with angle drives poppet shaft slow circumvolve, the impurity such as the ore pulp of in time cleaning alluvial in valve, rubble, prevent stuck malfunctioning to greatest extent; When ore slurry pump stops carrying, tapering valve gap, under the ore pulp effect of gravity and backflow, can fall flexibly, realizes non-return and closes, and avoids ore pulp to flow backwards.Due to the more extensive operation of mine, ore processing, unavoidably may there be the cement and the ceramic tile that compared with ratchel, braided bag, chemical combination pond, come off to block safety check, be convenient to safety check cleaning also particularly important, in the design, there is the clean-up port with spiral cover, on spiral cover, be also welded with and revolve hand, insert steel pipe, round steel, the wooden stick spiral cover of can easily outwarding winding, in time cleaning, has cleared up and screwing hermetic fast, easily.
The utility model can not only effectively prevent the ore pulp infringement that equipment is caused of flowing backwards, and can prevent to greatest extent that valve is stuck malfunctioning by impurity such as ore pulp, rubbles, when being in an emergency, also can open easily and efficiently valve body and clear up, meet the needs of mine, ore operation.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
In figure, each label represents:
1, valve body; 2, tapering valve gap; 3, blade with angle; 4, axle sleeve; 5, poppet shaft; 6, upper flange; 7, clean-up port; 8, spiral cover; 9, revolve hand; 10, supporting rib; 11, lower flange.
Embodiment
Now by reference to the accompanying drawings, the utility model is further illustrated.
Ore slurry pump safety check as shown in Figure 1, be illustrated as safety check opening state, comprise valve body 1, tapering valve gap 2, poppet shaft 5, blade 3 with angle and clean-up port 7, wherein material entrance is positioned at the bottom of valve body 1, valve body 1 bottom is connected with lower flange 11, discharge port is positioned at the top of valve body 1, valve body 1 top is connected with upper flange 6, tapering valve gap 2 is fixed in poppet shaft 5, poppet shaft can up and downly be opened or throttle down with this, there is multi-disc blade 3 with angle tapering valve gap 2 upper ends (in poppet shaft), blade 3 with angle is fixed in poppet shaft 5 and can drives poppet shaft 5 to rotate, in poppet shaft 5, there are upper and lower two axle sleeves 4, poppet shaft 5 use supporting ribs 10 support, one side of valve body 1 has clean-up port 7, clean-up port 7 is connected with spiral cover 8, on spiral cover 8, be connected with and revolve hand 9.
During ore slurry pump work, by ore slurry pump, drive ore pulp that tapering valve gap 2 is washed open, make safety check in open mode, meanwhile, under the driving of ore pulp, blade 3 with angle drives poppet shaft 5 slow circumvolves, the impurity such as the ore pulp of in time cleaning alluvial in valve, rubble, prevent stuck malfunctioning to greatest extent; When ore slurry pump stops carrying, tapering valve gap 2, under the ore pulp effect of gravity and backflow, can fall flexibly, realizes non-return and closes, and avoids ore pulp to flow backwards.When being in an emergency, in the time of need to opening valve body and clear up, the objects such as available steel pipe, round steel, wooden stick insert and revolve hand 9, the spiral cover 8 of easily outwarding winding, and cleaning in time, has cleared up and screwing hermetic fast, easily.
Above-mentioned is preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
