Abstract
The utility model relates to balance type electric multi-way valve. The utility model is characterized in that inlet joints (1), upper discharging joints (2), and lower discharging joints (7) are arranged on a valve body (3), wherein, the number of the upper discharging joints (2) is equal to the number of the lower discharging joints (7); a lining (4) is arranged in the valve body (3), and holes of which the number corresponds to the number of the upper discharging joints (2) and the lower discharging joints (7) are arranged on the lining; a piston (5) is arranged in the lining (4), and the piston (5) is connected with a valve rod (8); the valve rod (8) is driven by a motor (13) to move, and the distance of the movement of the valve rod (8) is controlled by a limiter (14). The utility model has the advantages of simple structure, accuracy and reliability, and the automatic control can also be realized.
Description
The utility model relates to a kind of valve.
At present, various valve series products can only play the open and close effect, while the effect that is to say, goes out, do not have the commutation change of current purpose.Particularly in the oil production technology of oil field, a metering station is made up of more than ten mouthfuls of oil wells, each metering station has only a metering mechanism, the daily output of more than ten mouthful of oil well is the every day of metering in turn, therefore, every mouthful of oil well must be by a threeway, and two gate valves are formed, it is defeated that one of them gate valve is used for collection, and a gate valve is used for metering.If when measuring the daily output of certain mouthful of well, the defeated gate valve of the collection of this mouthful well closes dead, opens the metering gate valve, all the other wells are all opened the defeated gate valve of collection, close the metering gate valve, and therefore, oil recovery workman's operation is very numerous and diverse, and labor intensity is very big.Misoperation often takes place simultaneously, and causes metering inaccurate.In the prior art, a kind of sphere three-way valve of electronic or hydraulic pressure is arranged, the defective that this three-way valve exists is the requirement on machining accuracy height, in case the wearing and tearing back with regard to leakage of oil, is difficult to repair, its cost of production is also very high.
The purpose of this utility model provides a kind of simple in structure, the electronic multiple-way valve of the balanced type of the easy to operate automatic reverse change of current.
The utility model is achieved in that inlet attack (1) on valve body (3), last discharge joint (2), following discharge joint (7), the quantity of last discharge joint (2) and following discharge joint (7) equates, lining (4) is arranged in the valve body (3), have hole on the lining (4) corresponding to last discharge joint (2) and following discharge joint (7) quantity, piston (5) is arranged in the lining (4), seal ring (6) is arranged on the excircle of piston (5), piston (5) is connected with valve rod (8), valve rod (8) is connected with valve mother (15), valve mother (15) is connected with gear (16), gear (16) is connected with motor (13), loam cake (10) is connected with the end flange (9) of valve body (3), bearing support (12) is connected with loam cake (8), motor (13) is fixed on bearing support (12) excircle, bearing (17) is housed in the bearing support (12), bearing (17) is located by valve mother (15), the displacement distance of valve rod (8) is determined by snubber (14), locating stud (11) is contained on the valve rod (8), and its upper end can contact with snubber (14).
Advantage of the present utility model is: 1, simple in structure, installation and maintenance are convenient.2, easy to operate, accurate, can realize automatic control; 3, cost is lower.
Accompanying drawing is the utility model structural drawing.
Below in conjunction with accompanying drawing with the utility model is further specified as follows:
As shown in the figure, have on the valve body (3) inlet attack (1), on discharge joint (2), following discharge joint (7), it is equal wherein to go up the quantity of discharging joint (2) and following discharge joint (7), and can be designed to some groups as required; Lining (4) is arranged in the valve body (3), have perforate on the lining (4) corresponding to last discharge joint (2) and following discharge joint (7) quantity; Piston (5) is arranged in the lining (4), seal ring (6) is arranged on the excircle of piston (5), the distance between two seal rings (6) is greater than the length of each perforate on the lining (4); Piston (5) is connected with valve rod (8), between valve rod (8) and the valve mother (15) by being threaded, valve mother (15) is connected with gear (16), gear (16) is connected with motor (13), loam cake (10) is connected with the end flange (9) of valve body (3), and bearing support (12) is connected with loam cake (10), and motor (13) is fixed on bearing support (12) excircle, bearing (17) is housed in the bearing support (12), and bearing (17) is located by valve mother (15); The displacement distance of valve rod (8) determines that by snubber (14) be equipped with on the valve rod (8) on the locating stud (11), locating stud (11) top can contact with snubber (14).
Working principle of the present utility model is: after liquid enters valve body (3) from inlet attack (1), under state shown in the accompanying drawing, liquid through piston (5) endoporus directly under discharge joint (7) and flow out, at this moment the seal ring (6) on piston (5) excircle blocks liquid, and it can not be flowed out from last discharge joint (2).Liquid commutation is when last discharge joint (2) flows out if desired, give (13) activating signals of motor, motor (13) rotates and rotates with regard to driven gear (16), gear (16) drives valve mother (15) again and rotates, valve mother (15) rotation just drives valve rod (8) and moves to left, thereby drive piston (5) left lateral, until piston (5) blocks down discharge joint (7), at this moment locating stud (11) presses snubber (14), make motor (13) outage and stop, liquid just flows out from last discharge joint (2) like this.Same principle as long as give the signal of (13) counter-rotatings of motor, can go up again and discharge joint (2) sealing, make liquid under discharge joint (7) outflow.
