Abstract
The utility model provides an automatic valve for a dispersing water hammer, which is suitable for a water conveying pipe net of a water conservancy engineering and a water supplying work. The method can automatically eliminate the water hammer action generated by any reason, which needs no external power and has versatility. The device formed by using the method has the advantages of equipment simplifying, easy operation, energy saving, coordinate action of start and closure of the brake and the valve, accuracy and safety, which relieves bulky physical labor.
Description
The utility model relates to a kind of valving of eliminating water hammering, and it is applied in the water transfer pipe network in hydraulic engineering and the water supply project.
In pump water delivery process, because of sudden power or the formed water hammer peak pressure of other reason can make pump and pipeline etc. suffer damage.Solution to this problem is that buffer valve is installed in water transfer pipe network at present, manually or facility such as electric gate valve, the shortcoming of this method is to eliminate the weak effect of water hammering, is difficult to accomplish accurate, safety, reliable, can not eliminate the water hammering that produces because of any reason.
The purpose of this utility model is exactly the device that the elimination water hammering in a kind of water transfer pipe network that is applied in hydraulic engineering and the water supply project is provided in order to overcome the shortcoming in the above-mentioned prior art, it is accurate, safe, effective that this device is eliminated water hammer, removed heavy manual labor.
The purpose of this utility model can adopt following measure to solve.
Control the keying of main line and pressure relief pipe gate valve by the variation of the pressure of water in the water-carriage system and the flow direction.Promptly the pressure of main line water and the variation of the flow direction are made response, utilize the pressure of water in the main line to carry out by control system as dynamic Control main line and the keying of pressure relief pipe gate valve by the induction system that places main line.
The device that uses said method is by main line, pressure relief pipe, pilot line, check valve plate, big small cylinder, four-way cock valve, compositions such as main line gate valve and pressure relief pipe gate valve.The mandrel of the rotating shaft of check valve plate and four-way cock valve links.Mark post on the size piston in hydraulic cylinder is associated with main line gate valve and pressure relief pipe gate valve respectively.
The drawing of accompanying drawing is described as follows:

Fig. 6 is the main sectional view of the utility model device;
Fig. 7 is the A-A sectional view among Fig. 6.
Fig. 8 is the utility model user mode figure.
The utility model is described in further detail below in conjunction with accompanying drawing:
In pump (1) water-carriage system, by the induction system that places main line (9) (2) pressure of main line (9) water and the variation of the flow direction are made response, utilize of the keying of the pressure of water in the main line (9) as dynamic Control main line gate valve (8) and pressure relief pipe gate valve (3) by control system (11).Drive system (7) (4) that the gate valve (8) (3) of main line (9) and pressure relief pipe (5) opens and closes and control system (11) exist the transmission relation (6) of signal and power, induction system (2) exists signal transmission relation (12) with control system (11), and control system (11) exists power transmission relation (10) with main line (9).
When pump (1) beginning water delivery, induction system (2) is delivered to control system (11) with the signal of experiencing through signal transmission relation (12), control system (11) opens main line gate valve (8) through power signal transmission relation (6) control-driven system (4) (7), pressure relief pipe gate valve (3) is closed, and water-carriage system enters proper functioning.
When termination of pumping, induction system (2) is also delivered to control system (11) through signal transmission relation (12) with the water pressure experienced and the variation of the flow direction, control system (11) closes main line gate valve (8) through power signal transmission relation (6) control-driven system (4) (7), pressure relief pipe gate valve (3) is opened, and water-carriage system enters the working procedure of dredging and stopping water hammer.
Using a kind of device of eliminating water hammering of said method is by main line (17), pressure relief pipe (16), pilot line (33), check valve plate (18), big small cylinder (14) (21), four-way cock valve (19), main line gate valve (23) and pressure relief pipe gate valve compositions such as (15).
When water-carriage system begins proper functioning, check valve plate (18) is kicked up under the effect of current to the almost horizontal state, because the rotating shaft (24) of check valve plate (18) links with the mandrel (31) of four-way cock valve (19), so also rotating, mandrel (31) make four-way cock valve (19) be in working state shown in Figure 2, it is press water in the main line (17) is injected into big small cylinder (21) (14) through pilot line (33) and four-way cock valve (19) bottom compartment (30) (25), piston (29) (26) rises, the water that will push up in the chamber (28) (27) is extruded in the pressure relief pipe (16) through pilot line (33) and four-way cock valve (19), because the mark post (20) (13) on the piston (29) (26) is associated with main line gate valve (23) and pressure relief pipe gate valve (15) respectively, so main line gate valve (23) promotes and opens thereupon, pressure relief pipe gate valve (15) promotes and closes, and whole water transport pipeline enters normal working.
When water-carriage system stops water delivery for some reason, the pressure of water and the inversionization of the flow direction fall check valve plate (18) in the main line (17), the mandrel (31) of four-way cock valve (19) rotates with rotating shaft (24), and this valve (19) is entered and the diametical working state of state shown in Figure 2.It is water in the main line (17) injects big small cylinder (21) (24) through pilot line (33) and four-way cock valve (19) chamber, top (28) (27), piston (29) (26) descends the water in the bottom compartment (30) (25) is flowed in the pressure relief pipe (16) through pilot line (33) and four-way cock valve (19), simultaneously, size mark post (20) (13) makes main line gate valve (23) fall to cutting out, pressure relief pipe gate valve (15) is opened, and the working state of water hammer is dredged and stopped to whole water transport pipeline.
The utility model provides a kind of method of feasible elimination water hammering, and the method can be eliminated the water hammering that produces because of any reason automatically, need not use external power, has versatility. Use the formed device of the method to have the simplification facility, easy operating, energy savings, the gate valve switching motion is coordinated, and accurately, safe and reliable advantage has been removed heavy manual labor. Remarkable through test effect.
