Abstract
The utility model discloses a slurry pump control valve of hydraulic valve plate type. The structure of the control valve is that an oil cylinder2 is arranged on the valve cap13; the oil cylinder2 is provided with a valve7 that is connected with a valve bar12; the end of the cylinder2 close to the valve cap13 is provided with a lower port10 that is connected with a hydraulic station6 through an one-way throttle valve11; the oil cylinder2 is provided with a middle port8 connected with the hydraulic station6 through a one-way throttle; the valve7 is provided with a marking bar of an extending cylinder2. The middle part8 is positioned at the 50 millimeter below the cylinder2. The utility model is plate type hydraulic valve with fast opening and slow closing, is specially used in the slurry system for adjusting valve opening speed.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of hydraulic brake template 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.
The model utility content
Technical problem to be solved in the utility model provides a kind of opening speed of the adjustable gate that is specifically designed to slag slurry system and changes down the hydraulic brake template slurry pump control valve of pass soon.
In order to solve the problems of the technologies described above, the hydraulic brake template slurry pump control valve that the utility model provides, comprise valve body, valve gap, flashboard and valve rod, on described valve gap, be provided with oil cylinder, in described oil cylinder, be provided with piston, described valve rod is connected with piston, the lower end that described oil cylinder closes on described valve gap one end is provided with lower end mouth, described lower end mouth is connected with hydraulic station by one-way throttle valve, top away from described valve gap one end is provided with upper end-hole, described upper end-hole is connected with described hydraulic station by throttle valve, described oil cylinder the above lower end mouth and upper end-hole between be provided with middle port, middle port is connected with hydraulic station by one-way valve.
On described piston, be provided with the sign bar that extends to outside the described oil cylinder.
Described middle port is located at 50 millimeters places, described oil cylinder bottom.
Adopt the hydraulic brake template slurry pump control valve of technique scheme, behind the starting mode of pump, hydraulic station energising work, hydraulic oil enters the below of piston through one-way throttle valve, promotes piston and slowly rises; Hydraulic oil with piston upper chamber enters hydraulic station simultaneously; Drive flashboard by piston rod and rise valve opening; Regulate the aperture of one-way throttle valve, i.e. the opening speed of adjustable gate; After the termination of pumping, hydraulic station has a power failure simultaneously, and in advance the pressure oil that stores enters the epicoele of oil cylinder through throttle valve, promotes piston and moves down fast; Hydraulic oil with the piston cavity of resorption enters hydraulic station simultaneously from middle port and lower end mouth simultaneously; When the lower end surface of piston was lower than middle port, the hydraulic oil of piston cavity of resorption can only be discharged from lower end mouth, and therefore, piston can only move down with slower speed, drove valve rod and flashboard and moved down, and valve is slowly closed; Regulate the aperture of one-way throttle valve, just the closing velocity of adjustable gate.
The utility model is a kind of opening speed of the adjustable gate that is specifically designed to slag slurry system and the hydraulic brake template slurry pump control valve that changes down the pass soon.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing, oil cylinder 2 is fixedlyed connected with valve gap 13 by bolt 1; The inner chamber of oil cylinder 2 piston 7 that can slide up and down, the lower end of the upper end of piston 7 and sign bar 3 is by being threaded, and the top cover of oil cylinder 2 is stretched out in the upper end of sign bar 3, but the adjustable height of indicator piston 7, valve rod 12 and flashboard 16; Valve rod 12 upper ends and piston 7 are by being threaded, and lower end and flashboard 16 adopt and flexibly connect; The lower end of valve gap 13 is connected with valve body 15 by flange bolt 14; Oil cylinder 2 is provided with upper end-hole 4 away from the upper end of valve gap 13 1 ends, and upper end-hole 4 is connected with hydraulic station 6 with throttle valve 5 by oil pipe; The lower end of closing on valve gap 13 1 ends is provided with lower end mouth 10, and lower end mouth 10 is connected with hydraulic station 6 with one-way throttle valve 11 by oil pipe; 50 millimeters places also are provided with middle port 8 in oil cylinder 2 bottoms, and middle port 8 is connected with hydraulic station 6 with one-way valve 9 by oil pipe.
Referring to accompanying drawing, its working principle:
Drive valve: behind the starting mode of pump, hydraulic station energising work, hydraulic oil enters the below of piston 7 through one-way throttle valve 11, lower end mouth 10, promotes piston 7 and slowly rises; Hydraulic oil with piston 7 epicoeles enters hydraulic station 6 through upper end-hole 4 simultaneously; Drive flashboard 16 by piston rod 12 and rise valve opening; Regulate the aperture of one-way throttle valve 11, i.e. the opening speed of adjustable gate;
Close valve: after the termination of pumping, hydraulic station has a power failure simultaneously, and the pressure oil that stores enters the epicoele of oil cylinder 2 through throttle valve 5, upper end-hole 4 in advance, promotes piston 7 and moves down fast; Hydraulic oil with piston 7 cavity of resorptions enters hydraulic station 6 simultaneously from middle port 8 and lower end mouth 10 simultaneously; When the lower end surface of piston 7 was lower than middle port 8, the hydraulic oil of piston 7 cavity of resorptions can only be discharged from lower end mouth 10, and therefore, piston 7 can only move down with slower speed, drives valve rod 12 and flashboard 16 and moves down, and valve is slowly closed; Regulate the aperture of one-way throttle valve 11, just the closing velocity of adjustable gate.
