Abstract
The utility model discloses a novel diaphragm-type quick-opening mud-discharging valve, which is formed by sequentially connecting a valve cover, a diaphragm seat and a valve body, wherein a control cavity is formed between the valve cover and the diaphragm seat, the control cavity is divided into an upper cavity and a lower cavity through a membrane, and an inner cavity is formed between the diaphragm seat and the valve body. The novel diaphragm-type quick-opening mud-discharging valve is characterized by also comprising an electromagnetic valve, wherein the electromagnetic valve is connected with both the upper cavity and the lower cavity of the control cavity, an air hole a of the electromagnetic valve is connected with compressed air, an air hole b is connected with an air hole at the top of the upper cavity of the control cavity through a hose, an air hole c is connected with the atmosphere, an air hole d is connected with an air hole of the lower cavity of the control cavity through a hose, and an air hole e is connected with the atmosphere. When the electricity of the electromagnetic valve is lost, the passages of the air hole a and the air hole b are opened, and the compressed air enters the upper cavity of the control cavity; the passages of the air hole d and the air hole e are opened, and the compressed air in the lower cavity of the control cavity is discharged into the atmosphere; and an air hole 3 is in a closed state. At the time, the pressure in the lower cavity of the control cavity is gradually decreased, the pressure in the upper cavity is gradually increased, and under the actions of upper and lower gas pressures, a valve plate is slowly closed without swinging, and a water hammer is markedly decreased.
Description
Technical field
The utility model relates to a kind of one-way valve, relates in particular to a kind of membrane type quick-opening mud valve.
Background technique
Conventional coagulation-filtrations water preparation process is that former water enters the direct dosing coagulation of tube settler postprecipitation, and sludge volume is bigger, so selects for use silt liquid insensitive membrane type quick-opening mud valve that deposits.According to 4.1 regulations of " membrane type quick-opening mud valve " (CJ/T196-2004) city-building industry standard: the Lift of valve plate is not less than 1/2 of inside nominal diameter.In the actual using process of existing soil discharging valve, pressurized air is to enter after the ball valve of cavity of resorption opposite side is discharged from cavity of resorption by solenoid valve, after valve plate is opened to the height spoil disposal end of regulation, because the differential static pressure and the effect of valve plate self gravitation of tube settler, the water hammer that closes the valve generation makes the gland and the flange place leather packing of soil discharging valve and control gate valve collapse to fall to leak.Be that ball valve was opened conference and caused valve body to burst apart, open too small meeting and valve plate occurs and swing up and down that spoil disposal can't stop.And because the differential static pressure of tube settler objective reality, soil discharging valve can't be accomplished Slow Close, causes the soil discharging valve maintenance frequent, shorten working life.
The model utility content
Problem to be solved in the utility model provides a kind of novel membrane type quick-opening mud valve, and it can reduce the water hammer that existing soil discharging valve occurs in closing course, thereby prolongs the life-span of soil discharging valve.
A kind of membrane type quick-opening mud valve of the utility model, by valve gap, the diaphragm seat, valve body is connected in sequence, form control chamber between valve gap and the diaphragm seat, barrier film is divided into two chambeies up and down with control chamber, form inner chamber between diaphragm seat and the valve body, the valve rod upper end is passed the back and is directly linked to each other with valve gap by spring from barrier film, the valve rod lower end is connected with valve plate, it is characterized in that: further comprising the solenoid valve that all is connected with the upper and lower cavity of control chamber, the pore a of solenoid valve connects pressurized air, and the top of chamber pore is connected with flexible pipe on pore b and the control chamber, and pore c links to each other with atmosphere, pore d is connected with flexible pipe with control chamber cavity of resorption pore, and pore e links to each other with atmosphere.
When solenoid valve gets when electric, pore a and pore d passage are opened, the control chamber cavity of resorption entrance pressure air that contracts; Pore b and pore c passage are opened, and the pressurized air in the control chamber epicoele is discharged in the atmosphere; Pore e is in closed condition.At this moment, valve plate is opened rapidly, discharges the passage that muddy water forms between valve plate and valve body.
When the solenoid valve dead electricity, pore a and pore b passage are opened, the control chamber epicoele entrance pressure air that contracts; Pore d and pore e passage are opened, and the pressurized air in the control chamber cavity of resorption is discharged in the atmosphere; Pore 3 is in closed condition.At this moment, the pressure in the control chamber cavity of resorption reduces gradually, and the pressure in the epicoele rises gradually, and under the effect of gas pressure up and down, valve plate is slowly closed does not have swing, and water hammer obviously reduces.
Basis is novel to guarantee to have reduced the generation of water hammer under the prerequisite that soil discharging valve is not stopped up by foreign material, has avoided the soil discharging valve vibrations impaired, has prolonged the life-span of soil discharging valve.

Embodiment
As can be seen from Figure 1, a kind of membrane type quick-opening mud valve of the utility model, by valve gap 1, diaphragm seat 2, valve body 3 is connected in sequence, form control chamber between valve gap 1 and the diaphragm seat 2, barrier film 5 is divided into two chambeies up and down with control chamber, form inner chamber between diaphragm seat 2 and the valve body 3, valve rod 4 upper ends are passed the back and are directly linked to each other with valve gap 1 by spring from barrier film 5, valve rod 4 lower ends are connected with valve plate 6, it is characterized in that: further comprising the solenoid valve 7 that all is connected with the upper and lower cavity of control chamber, the pore a of solenoid valve 7 connects pressurized air, the top of chamber pore is connected with flexible pipe 8 on pore b and the control chamber, pore c links to each other with atmosphere, and pore d is connected with flexible pipe 9 with control chamber cavity of resorption pore, and pore e links to each other with atmosphere.
When solenoid valve 7 when electric, pore a and pore d passage are opened, the control chamber cavity of resorption entrance pressure air that contracts; Pore b and pore c passage are opened, and the pressurized air in the control chamber epicoele is discharged in the atmosphere; Pore e is in closed condition.At this moment, valve plate 6 is opened rapidly, discharges the passage that muddy water forms between valve plate 6 and valve body 3.
When the solenoid valve dead electricity, pore a and pore b passage are opened, the control chamber epicoele entrance pressure air that contracts; Pore d and pore e passage are opened, and the pressurized air in the control chamber cavity of resorption is discharged in the atmosphere; Pore 3 is in closed condition.At this moment, the pressure in the control chamber cavity of resorption reduces gradually, and the pressure in the epicoele rises gradually, and under the effect of gas pressure up and down, valve plate is slowly closed does not have swing, and water hammer obviously reduces.
As this novel a kind of optimal way, the pore e of solenoid valve 7 links to each other with atmosphere by decompression exhaust valve 10.Because pore e has installed decompression exhaust valve 10, and the pressure of control chamber epicoele is further reduced, and makes valve plate 6 descend slowlyer, has further reduced water hammer.
The ball valve 11 that is connected control chamber cavity of resorption opposite side is normally closed, is connected with source of the gas.When power failure or solenoid valve 7 damages, can open ball valve 11 and replace solenoid valves 7 work.Consider that yard piping freezes with tap water winter easily, this novel driven medium has adopted pressurized air.
