Abstract
The utility model discloses a pressure-balanced siphon breaking valve used for siphon flow channel, which is composed of a valve body, a valve shaft, valve clacks and an electromagnetic drive mechanism. An energy storage spring is sleeved on one end of the valve shaft; the valve shaft passes through two valve holes on a single-cavity valve body which share a same center line; the valve shaft is provided with two valve clacks; the electromagnetic drive mechanism is composed of an electromagnet body and a displacement component; the electromagnetic drive mechanism is arranged on the valve body; the displacement component is a lever which is contactedly pressed with the valve shaft. Compared with the prior art, the utility model has the advantages of small size and low production cost; moreover, the electromagnetic drive mechanism is characterized by simple structure, as well as practical and reliable performances.
Description
Technical field
The utility model relates to a kind of of water supply and sewage work and prevents that high-order water from along the device that the hydrocone type pipeline flows backwards, particularly relating to the siphon destructive valve of syphon runner.
Background technique
Siphon destructive valve is the visual plant that is used for hydrocone type runner rivers water lift pumping plant, and it is installed on the hump of hydrocone type runner.When water pump assembly generation dead electricity accident or normal termination of pumping, fly the ease counter-rotating in order to prevent water pump assembly, guarantee the safety of unit equipment, need to open rapidly the siphon destructive valve valve, allow air enter runner, destroy siphon and current are cut off.The siphon destructive valve of a kind of single chamber single-lobe formula on engineering because the gas pressure difference of closing inside and outside the valve rear chamber is bigger, causes the start-stop device complex structure of this type of siphon destructive valve at present, so easy break-down.The siphon destructive valve that has occurred a kind of two-chamber bivalve lobe recently again, this valve have exocoel and two active chambers of inner chamber, i.e. air cavity and water cavity.Valve shaft passes exocoel and inner chamber, and two flaps are gone here and there at interval on valve shaft, and mobile valve shaft makes two flaps be pressed together on the valve seat on the inner chamber or lifts off a seat, and can cut off or be communicated with inside and outside two chambeies, plays the effect that keeps siphon or destroy the siphon state.The valve core structure of this bivalve lobe formula makes the valve body internal and external pressure balance, and valve opening force or pass valve power are constant, are not subjected to the influence of inside and outside differential pressure, make valve opening and closing simple in structure, reliable operation.Because this two-chamber bivalve valve structure is to transplant from traditional two-chamber bivalve lobe modulating valve to come, therefore there is the big and high shortcoming of cost of volume, valve opening and closing mechanism is arranged on the end points of valve shaft elongation line usually in addition, also causes the valve body axial length long, makes valve body long-pending more huge.
Summary of the invention
Technical problem to be solved in the utility model is by the improvement to two-chamber bivalve lobe formula siphon destructive valve, under same volume flow, makes the long-pending weight of dwindling greatly, also alleviating valve simultaneously of valve body, makes things convenient for the assembling and the debugging of valve, reduces its cost of production.
The utility model is realized by following technological scheme.
A kind of pressure balance type siphon destructive valve that is used for syphon runner, form by valve body, valve shaft, flap and electromagnetic drive mechanism, energy storage spring be enclosed within be equipped with in the valve opening that two flaps, valve shafts are through two concentricity lines on the valve body on valve shaft one end, the valve shaft, electromagnetic drive mechanism is made of an electromagnet ontology and displacement component, it is characterized in that described valve shaft is through in the valve opening of two concentricity lines on the single cavity body of valve.
In order to shorten the valve body axial length, electromagnetic drive mechanism can be provided with on the valve body, described displacement component is a lever, this lever lower end presses mutually with valve shaft.
By researching and analysing, the design people finds that the exocoel of two-chamber bivalve lobe formula siphon destructive valve communicates with atmosphere, exocoel can remove fully, adopt single chamber bivalve lobe pressure balance type structure, can reach the work effect of two-chamber bivalve lobe formula siphon destructive valve equally, compare with two-chamber bivalve lobe formula siphon destructive valve, make valve body long-pending narrow down to original volume 1/3rd, the weight of valve also alleviated 50 percent, help the assembling and the debugging of valve, cost of production is obviously reduced.In addition, because electromagnetic drive mechanism is provided with on the valve body, displacement component adopts a lever and the structure that lower end and valve shaft press mutually, and the axial length of valve is shortened, and it is long-pending to have reduced valve body, and makes the displacement component structure more simple and reliable.
Description of drawings
Fig. 1 is the siphon destructive valve structural representation that the utility model provides.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment
In Fig. 1, this siphon destructive valve is made up of single cavity body of valve 5, energy storage spring 3, valve shaft 9, flap 10, electromagnetic drive mechanism 6 (this mechanism will describe below).On single cavity body of valve 5, have the valve opening of two horizontal concentricity lines, valve seat 11a is housed on the valve opening, 11b, two flap 10a of fixed installation on described valve shaft 9,10b, these two flap 10a, 10b and described valve seat 11a, 11b matches, valve shaft 9 passes in the valve opening of two horizontal concentricity lines on the single cavity body of valve 5, energy storage spring 3 is enclosed within the left end of valve shaft 9, one spring seat board 2 is arranged at its bottom, valve shaft 9 two ends are inclusive in the bearing 1a that has self-lubricating layer, in the 1b, bearing 1a, 1b is installed in bearing bracket 4a respectively, on the 4b, bearing bracket 4a, 4b is fixedlyed connected with valve body 5.In order to shorten the axial length of valve, electromagnetic drive mechanism can be placed the top of valve body 5.Electromagnetic drive mechanism 6 is made up of an electromagnet ontology and a lever that produces electromagnetic force, the top of moving iron core in the electromagnet ontology by top thick stick 7 and lever 8 is roof pressure mutually, lever 8 top appropriate locations are provided with a fulcrum, this fulcrum one end is fixedlyed connected with valve body, leaning on the valve shaft at flap 10b place, have a groove, insert in this groove lever 8 lower ends.
In order more to help pressing between lever and flap and the valve shaft, crooked α angle between the end portion of lever 8 and the thick stick body, as shown in Figure 1, the α angle is preferably 15 degree; The lower end afterbody of lever 8 can be made fork-shaped, and lever 8 fork-shaped lower ends are clamped valve shaft and are pressed on the flap 10b.
When electromagnet was switched on, moving iron core is roof pressure fork shape lever to the right, and fork shape lever lower end promotes valve shaft to left movement, flap is pressed on the valve seat, and at this moment, body cavity is hedged off from the outer world, make siphon destructive valve keep the rough vacuum working state, at valve shaft compressed energy-storage spring in left movement.When the electromagnet dead electricity, moving iron core resets, the ineffective power of fork shape lever, the pressurized energy storage spring resets and drives valve shaft and move right, flap on the valve shaft breaks away from valve seat, and at this moment, ambient air enters body cavity, body cavity siphon state is destroyed, causes the rainbow shape water delivery in-pipe flow cutout of siphon destructive valve below.
