Abstract
The utility model discloses a self-force plug cock type control valve for a slurry pump; a valve shaft (16) is connected with one end of a lever (7), the other end of which is provided with a heavy hammer (6); the lower end of a piston cylinder (14) is articulated with a base seat (8); a piston rod (12), the upper end of which is connected with the lever (7) by an electromagnetic clutch (15), is provided with a spring (13); one end of a control oil pipe (1) is connected with one end of a pressure converter (3) by an orifice check valve (2), the other end is communicated with the lower chamber of the piston cylinder (14); the other end of the pressure converter (3) is communicated with the inner chamber of a valve body (5). The utility model is a safe self-force plug cock type control valve for the slurry pump, which is mainly used for the slurry pump outlet and has functions of preventing reflux, pump starting without load, abating water hammer, automatic control, etc., effectively protecting water pumps and pipe-network equipment.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of slurry pump control valve.
Technical background
Existing control valve for water pump has multiple pattern, but all can only be used for the foul sewer system of clear water and no abrasion.Because the abrasion of slag slurry system is very strong, stop up small-bore pipeline and valve again easily, therefore, existing control valve for water pump all can not be used for slag slurry system.Present slurry pump control valve does not have that anti-backflow, zero load open pump, subdue water hammer, function such as control automatically, can not effectively protect the safety of water pump and pipe network equipment.
The model utility content
Technical problem to be solved in the utility model provides a kind of slag stock pump outlet that is mainly used in; have that anti-backflow, zero load open pump, subdue water hammer, function such as control automatically, effectively protect the self-force turncock type slag stuff pump control valve of the safety of water pump and pipe network equipment.
In order to solve the problems of the technologies described above, the self-force turncock type slag stuff pump control valve that the utility model provides, comprise valve body and base thereof, be installed in spool in the valve body by valve shaft, described valve shaft is connected with lever one end, the described lever the other end is provided with weight, and the lower end of piston cylinder is hinged on the described base; Described piston rod is provided with spring; Described piston rod upper end is connected with described lever by magnetic clutch; Control oil pipe one end links to each other with pressure converter one end by the throttling one-way valve, and the other end is communicated with the cavity of resorption of described piston cylinder, and the described pressure converter the other end is communicated with described body cavity.
Adopt the self-force turncock type slag stuff pump control valve of technique scheme, behind the starting mode of pump, upstream pressure raises gradually, by pressure converter with valve before pressure medium be converted to hydraulic fluid pressure, hydraulic oil enters the piston cylinder cavity of resorption through throttling one-way valve and control oil pipe, and it is up to promote piston rod; When water pump energising starts, the magnetic clutch action of switching on simultaneously, piston rod and lever is hinged, and therefore, when piston rod rose, by lever drives valve shaft and the rotation of spool clockwise direction, valve was slowly opened; During termination of pumping, magnetic clutch outage, lever separates with piston rod, under the effect of weight, lever drives valve shaft and spool be counterclockwise about quick rotation 70 degree, about valve quick closedown 70 degree after, be subjected to the support of piston rod, no longer quick closedown; By hydraulic jack control, slowly close about 20 remaining degree.Piston rod slowly drops to initial position under the effect of spring, hydraulic oil pressure is back in the pressure converter; Wait for and drive valve next time.
The utility model is mainly used in slag stock pump outlet, has that anti-backflow, zero load open pump, subdue water hammer, function such as control automatically, effectively protects the safety of water pump and pipe network equipment.
In sum, the utility model is a kind of slag stock pump outlet of being mainly used in, and has that anti-backflow, zero load open pump, subdue water hammer, function such as control automatically, effectively protects the self-force turncock type slag stuff pump control valve of the safety of water pump and pipe network equipment.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation;
Fig. 2 is along A-A line sectional view among Fig. 1.
Among the figure: 1-control oil pipe, 2-throttling one-way valve, 3-pressure converter, 4-spool, 5-valve body, 6-weight, 7-lever, 8-base, 9-rear end cover, 10-bearing, 11-piston, 12-piston rod, 13-spring, 14-piston cylinder, 15-magnetic clutch, 16-valve shaft, 17-front cover, 18-bolt.
Embodiment
Referring to Fig. 1 and Fig. 2, control oil pipe 1 one ends link to each other with pressure converter 3 one ends by throttling one-way valve 2, and the other end is communicated with the cavity of resorption of piston cylinder 14, and pressure converter 3 the other ends are communicated with valve body 5 inner chambers; Bearing 10 on the lower end of piston cylinder 14 and the base 8 is hinged, free to rotate; Be with spring 13 on the piston rod 12, and place the inside of piston cylinder 14; Piston rod 12 upper ends are connected by magnetic clutch 15 with lever 7, can relatively rotate; The left end of lever 7 and weight 6 are fixing, and right-hand member and valve shaft 16 are fixing; The valve shaft 16 at spool 4 two ends places the axis hole on front cover 17 and the rear end cover 9 respectively, and is free to rotate; Front cover 17 is connected with valve body 5 by bolt 18 with rear end cover 9; Valve body 5 links to each other with base 8 by bolt 18.
Referring to Fig. 1 and Fig. 2, its working principle:
Drive valve: behind the starting mode of pump, upstream pressure raises gradually, by pressure converter 3 pressure medium before the valve is converted to hydraulic fluid pressure, and hydraulic oil enters piston cylinder 14 cavity of resorptions through throttling one-way valve 2 and control oil pipe 1, and it is up to promote piston rod 12; When water pump energising starts, magnetic clutch 15 action of switch on simultaneously, piston rod 12 and lever 7 is hinged, and therefore, when piston rod 12 rose, by lever 7 drive valve shafts 16 and the rotation of spool 4 clockwise directions, valve was slowly opened;
Close valve: during termination of pumping, magnetic clutch 15 outages, lever 7 separates with piston rod 12, under the effect of weight 6, lever 7 drives valve shafts 16 and spool 4 counterclockwise about quick rotation 70 degree, about valve quick closedown 70 degree after, be subjected to the support of piston rod 12, no longer quick closedown; By hydraulic jack control, slowly close about 20 remaining degree.Piston rod 12 slowly drops to initial position under the effect of spring 13, hydraulic oil pressure is back in the pressure converter 3; Wait for and drive valve next time.
Major function: the utility model is mainly used in slag stock pump outlet, has that anti-backflow, zero load open pump, subdue water hammer, function such as control automatically, effectively protects the safety of water pump and pipe network equipment.
