Abstract
The utility model relates to a hydraulic water level control valve which comprises a valve body and a valve cover, wherein, the valve body is a three-way cavity; the center of the valve body is provided with a throttling nut and a valve rod; the lower end of the valve rod is provided with a filter; the center of the valve rod is provided with a through hole from top to bottom; a diaphragm is arranged between an upper cavity and a side cavity of the valve body; a valve flap gasket is arranged between the side cavity and a lower cavity; a guide press cover with three claws is arranged between the valve flap gasket and the lower cavity; the valve flap gasket, the guide press cover and the valve rod are fixed through spigot nuts. The hydraulic water level control valve of the utility model has the advantages of principal control, novel structure, science, reasonability, simplicity, stable and reliable operating state, flexible start in the range of specified working pressure, no water hammer impact, raw material saving, light weight, small size, low cost and convenient installation and maintenance.
Description
The utility model is a kind of altitude valve, and particularly a kind of hydraulic water level control valve is mainly used in the water receivers such as water tank, pond and water tower of industrial and mining enterprises and covil construction, is used for automatic control water level.
Promptly when the water level in the water receiver is lower than assigned position, open valve automatically and enter, when water level reaches assigned position, close valve automatically and stop into water by water.
Prior art is that ball-cock assembly is seen Fig. 3, and there is ball float 28 cross bar 27 outer ends that are connected with valve rod 26, and valve body 29 is loaded in the water receiver, and the other ring flange 30 of valve body is communicated with inlet channel.When in the water receiver during decline of water table, ball float affects cross bar to descend, and valve 31 is opened, and water enters and injects water receiver downwards from other mouth.When treating that water level reaches assigned position, ball float drives valve rod by cross bar and valve rises, and closes until valve, stops to the water receiver water filling.Its weak point is: ball float is big, and one-piece construction is heavy; Because valve is loaded in the water receiver, install and the maintenance inconvenience.
The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of be loaded on water receiver outer, adopt that hydraulic pressure closes that valve, structure are light and handy, installation and maintenance hydraulic water level control valve easily.
The hydraulic water level control valve of the utility model design comprises valve body and valve gap, and three position control pawls are arranged on the described valve gap inside surface; Described valve body is the threeway cavity, and valve body central authorities are provided with throttling nut and valve rod, and valve rod central authorities are provided with a through hole from top to bottom; Between valve body epicoele and other chamber, be provided with diaphragm, between epicoele and diaphragm, be provided with upper press cover, between other chamber and diaphragm, be provided with flap, fix by coupling bolt between described upper press cover, diaphragm and the flap; Between other chamber and cavity of resorption, be provided with the flap pad, between flap pad and cavity of resorption, be provided with the guiding gland that has three pawls, fix by spigot nut between described flap pad, guiding gland and the valve rod.
The hydraulic water level control valve of the utility model design can also comprise the filtrator that the valve rod lower end is provided with.
The hydraulic water level control valve utilization utilization principle control of the utility model design, novel structure, scientific and reasonable, simple; Duty is steadily reliable, opens flexibly no impact of water hammer in the working pressure scope of regulation; Save starting material, in light weight, volume is little, cost is low, and installation and maintenance are convenient.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
The hydraulic water level control valve cross-sectional schematic that Fig. 1 designs for the utility model;
Scheme of installation when Fig. 2 uses for the utility model;
Fig. 3 is the synoptic diagram of prior art ball-cock assembly.
Wherein, label 1 is a valve body, and 2 is valve gap, 3 is bolt, and 4 is diaphragm, and 5 is upper press cover, 6 is coupling bolt, and 7 are the throttling nut, and 8 is valve rod, 9 is flap, and 10 is the flap pad, and 11 is filtrator, 12 are the guiding gland, and 13 is y-type filter, and 14 is hydraulic water level control valve, 15 is stop valve, and 16 is control tube, and 17 is ball-cock assembly, 18 is water receiver, and 19 is epicoele, and 20 is cavity of resorption, 21 is through hole, and 22 is other chamber, and 23 is gusset, 24 for filtering locknut, and 27 is cross bar, and 28 is ball float, 29 is valve body, and 30 is ring flange, and 31 is valve.
As shown in Figure 2, device of the present utility model and water-in and water-out pipeline and controlling plumbing fixtures UNICOM piping system structure so that the water receiver water level is controlled automatically.The utility model places the outside of water receiver, and there is stop valve 15 in the water inlet pipe UNICOM of a side and y-type filter 13 on the controlling plumbing fixtures that the opposing party is communicated with, and there is light and handy small-sized ball-cock assembly 17 the controlling plumbing fixtures lower end.
During use, when in the water receiver during decline of water table float of ball-cock assembly sagging, drive small-sized ball-cock assembly and open, valve body epicoele 19 is communicated with atmosphere, press in the epicoele and be normal pressure, be lower than the intake pressure in the cavity of resorption 20, water inlet holds up valve rod rises, and moves on the diaphragm, range up to the position control pawl lower end that reaches in the valve gap, at this moment, flap is opened, water inlet water filling in water receiver through other chamber 22 and outlet conduit.Simultaneously, press water is in valve rod center through hole 21 enters epicoele 19, and the surplus water in the epicoele enters in the water receiver from ball-cock assembly through controlling plumbing fixtures.When treating that water level rises to predetermined water level, float rises ball-cock assembly is closed, and hydraulic pressure equates with cavity of resorption in the epicoele, and because of last cavity area is bigger than cavity of resorption valve port area, surplus water is closed valve stem depressions in the epicoele until cavity of resorption water inlet valve port, stops water filling in water receiver.
Before this valve is installed, should pipe flushing is clean, in use, the maintenance one in a year of visual water quality situation is to for several times, and concrete maintenance method is as follows: 1, close the preceding gate valve of this valve; 2, remove control tube, screw off the valve gap bolt, open valve gap; 3, take out valve interior diaphragm, valve rod, flap and guiding gland etc.; 4, screw off the diaphragm plate screw, throttling nut, filtrator; 5, pull down upper press cover, diaphragm, flap, sealing gasket, guiding gland etc.After the dismounting, clean each part, remove dirt and various dirty foreign material, with aperture on the steel wire mediation throttling nut, filter rinsed etc. are changed the seal that has damaged.Assemble sequence and disassembly sequence are opposite.
