Abstract
The utility model discloses a high precision flow control valve which overcomes the defects of not high flow control and adjustment precision of current like products. The high precision flow control valve comprises a valve body and a first electromagnetic valve arranged on the vale body; the side wall of the valve body is fixed with a pin valve; the valve body is provided with a vertical channel C which is communicated with the mouth of the first electromagnetic valve and the cavity of the pin valve; the mouth of the first electromagnetic valve is communicated with the interface B of the valve body; the valve body is provided with a second electromagnetic valve and a horizontal channel D; the cavity of the second electromagnetic valve is communicated with the interface A of the valve body; the horizontal channel D is communicated with the cavity of the pin valve and is arranged at the pipe interface of the side wall of the valve body; a conical block is arranged in the horizontal channel D; the upper part of the conical block is communicated with the mouth of the second electromagnetic valve. The high precision flow control valve implements secondary adjustment on gas-liquid flow on which primary adjustment is implemented through the part of the pin valve; therefore, the high precision flow control valve can obtain high precision flow control effect. The high precision flow control valve can be widely applied to automatic control fields like shipbuilding industry, petrochemical industry, medical equipment, food, etc.
Description
Technical field
The utility model relates to a kind of high-precision flow control valve product manufacturing technology that the gas-liquid flow is accurately controlled, regulated that is used for.
Background technique
The flow control valve product is mainly used in accurate control and the adjusting to gas-liquid flow in the pipeline, be a kind of comparatively common automation controlling parts, it is widely used in fields such as boats and ships heavy industry, petrochemical industry, electrical circuitry equipment, medical equipment, industrial furnace, drying equipment, fire-protection equipment, Heating,Ventilating and Air Conditioning (HVAC), cleaning equipment, electro dipping, food industry, vacuum line, water factory's siphonic system.This type of relatively typical product such as State Intellectual Property Office on September 23rd, 2009 notice of authorization, name is called the utility model patent technology that " gas flow regulating valve " patent No. is ZL200820232727.2, it comprises " be provided with the valve seat of bringing pore and air outlet hole into; valve seat is provided with groove; the groove both sides are provided with the pore that is connected with inlet hole and air outlet hole; valve seat is provided with solenoid valve; the valve rod of solenoid valve matches with groove, be provided with at least on the valve seat two cover grooves and with the solenoid valve of groove fit.Valve seat is provided with valve opening, and valve opening intersects with air outlet hole and is communicated with, and is provided with needle-valve in the valve opening, and needle-valve is threaded with valve opening.The utility model has advantages such as novel structure, energy saving, reduction pollution owing to adopt said structure." still, this product only is provided with the needle-valve controlling device one, when the gas-liquid inlet pressure was higher, the control of its delivery outlet flow and degree of regulation awaited further raising, so limited widening of this series products application area and occasion greatly.
The model utility content
The technical problems to be solved in the utility model is to overcome existing like product flow control and not high deficiency and the defective of degree of regulation, provide a kind of flow control valve product of tool two-stage control gear to society, with satisfy various fields highi degree of accuracy such as boats and ships heavy industry, petrochemical industry, medical equipment, food industry, automation control is used required.
The technological scheme that its technical problem that solves the utility model adopts is: the high-precision flow control valve comprises valve body and is located at first solenoid valve of described valve body, described body wall is fixed with needle-valve, described valve body is provided with vertical passage C and is communicated with described first solenoid valve valve port and described needle-valve valve pocket, and described valve port is communicated in the interface B of described valve body; Described valve body is provided with second solenoid valve and horizontal channel D, and the described second solenoid valve valve pocket is communicated with the interface A of described valve body, and described horizontal channel D is communicated with described needle-valve valve pocket and is located at the interface tube of described body wall; Be provided with cone blocking in the described horizontal channel D, described cone blocking top is communicated with the described second solenoid valve valve port.
Described cone blocking bottom is provided with the bottom plug that is rotatably connected in described valve body, is provided with spring between described bottom plug and the described cone blocking.
The utility model high-precision flow control valve is provided with second solenoid valve and horizontal channel D at valve body, and the second solenoid valve valve pocket is communicated with the input interface A of valve body, is provided with the spring-supported cone blocking of tool in the D of horizontal channel; When gas-liquid pressure that interface A enters act on the cone blocking top and greater than spring force after, the gas-liquid flow behind the D of horizontal channel, route interface tube output, the first solenoid valve valve port cavity is gone into through needle-valve taper port is laggard in another road; After once regulating thus, just opened after the input interface A that guarantees this product reaches amount pressure, effectively ensured the Security of flow control valve product work; By needle valve member the gas-liquid flow of once having regulated is carried out secondary again and regulate, thereby can obtain high-precision flow control effect at interface B.Compare than existing product, have features simple structure, novel, advantage that Security is good, can be widely used in automation control area such as boats and ships heavy industry, petrochemical industry, medical equipment, food industry.
