Description
Technical field
The utility model relates to the control switch of flow of fluid, particularly relates to a kind of valve utilizing elastic material to be controlled by gas pressure.
Background technique
Usually pneumatic valve mainly contains pneumatic actuator (cylinder) at present, valve two critical pieces are formed, pressurized air (air compressor) is utilized to be power source, go to drive pneumatic actuator (cylinder) by solenoid valve commutation, by the unlatching of the movement of pneumatic actuator or rotating band movable valve with closed.Usual pneumatic actuator and valve are closely connected, but belong to again two different mechanisms simultaneously, and manufacture manufacturer different again, so the volume of general pneumatic valve is comparatively large, the installing space of needs is larger; Cylinder greatly can increase the manufacture cost of cylinder under the environment such as high temperature, heavy oil, corrosive gas, vacuum simultaneously, also can reduce the working life of cylinder; And for when being the pipeline of fluid by the mixing cured material of AB, very high requirement is had to the material of valve, structure, accuracy, corresponding valve manufacture cost is higher, and due to fluid can in time, temperature and solidifying, valve needs frequent cleaning even to need to replace; Once need replacement will replace whole valve, cost is higher.
The content of model utility
The purpose of this utility model is to provide a kind of compact structure, volume is little, manufacture cost is lower, control is convenient, is suitable for the pipeline that needs are are often unpicked and washed, and can safeguard again simple, alternative costs are low, can the valve of Automated condtrol.
In order to reach above-mentioned requirements, the utility model is realized by following scheme: it comprises central tube, it is characterized in that the centre of described central tube is provided with partition, central tube is separated into the liquid inlet pipe directly do not communicated and drain pipe, the inlet opening be interlinked to the outside in the liquid inlet pipe and drain pipe of nearly partition both sides are drilled with respectively and liquid outlet opening, in the resilient rubber hose of central tube appearance surface cover of inlet opening and liquid outlet opening position, the intimate of rubber hose and central tube is fitted, outer sleeve is had in the outer surface cover of central tube and rubber hose, on the inlet opening of outer sleeve and the inwall of liquid outlet opening corresponding position, be provided with the arc groove of circumference, outer sleeve is established pressurized air access port, pressurized air can enter between groove and rubber hose through access port, rubber hose is sealed by compressed-air actuated being turned on or off or not sealed inlet opening and liquid outlet opening, realize the opening and closing of valve.
Describedly compressed-air actuatedly to be turned on or off by electromagnetic valve.
Described inlet opening and liquid outlet opening were respectively two of central tube shaft axis to perforation, and inlet opening and liquid outlet opening are mutually right angle.
According to the aeroelasticity switching flow valve that such scheme manufactures, by the compressed-air actuated conducting of electromagnetic valve and disconnection, can the closedown of control valve rapidly and unlatching.When valve needs cleaning or replaces, only first need pull down outer sleeve, then take off rubber hose, finally pull down central tube to its dredging and cleaning.There is no mechanical motion just because of central tube, do not produce mechanical wear, as long as clean up without the need to replacing; And outer sleeve does not contact with fluids within pipes, without the need to cleaning and replacing; Only have rubber hose aging and distortion to need timing to change, and be on market easily buying to and the very cheap accessory of price, therefore maintenance cost is lower.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
Fig. 1, Fig. 2 are the structural representations of aeroelasticity switching flow valve.As seen from the figure, it comprises central tube 1, is provided with partition 2 in the centre of central tube 1, and central tube 1 is separated into the liquid inlet pipe 3 directly do not communicated and drain pipe 4.The inlet opening 5 be interlinked to the outside in the liquid inlet pipe 3 and drain pipe 4 of nearly partition 2 both sides are drilled with respectively and liquid outlet opening 6.Described inlet opening 5 and liquid outlet opening 6 were respectively two of central tube 1 shaft axis to perforation, and inlet opening 5 and liquid outlet opening 6 are mutually right angle as shown in Figure 3.The outer surface of the central tube 1 of inlet opening 5 and liquid outlet opening 6 position overlaps resilient rubber hose 7, and rubber hose 7 is fitted with the intimate of central tube 1.There is outer sleeve 8 in the outer surface cover of central tube 1 and rubber hose 7, on the inlet opening 5 of outer sleeve 8 and the inwall of liquid outlet opening 6 corresponding position, be provided with the arc groove 9 of circumference.Outer sleeve 9 is established pressurized air access port 10, and pressurized air can enter between groove 9 and rubber hose 7 through access port 10, rubber hose 7 is sealed or is not sealed inlet opening 5 and liquid outlet opening 6, realize the opening and closing of valve by compressed-air actuated being turned on or off.Describedly compressed-air actuatedly to be turned on or off by electromagnetic valve.
In use, when accessing pressurized air in pressurized air access port 10, pressurized air enters between groove 9 and rubber hose 7, pressurizeed in the periphery of rubber hose 7, make the inwall of rubber hose 7 be close to the cylindrical of central tube 1, also seal inlet opening 5 mouthfuls and liquid outlet opening 6 mouthfuls simultaneously, make inlet opening 5 and liquid outlet opening 6 not connected, liquid inlet pipe 3 and drain pipe 4 not connected, namely aeroelasticity switching flow valve close state as shown in Figure 1 and Figure 2.When non-compressed air access in pressurized air access port 10, the liquid of pressure is had rubber hose 7 to be pushed open through inlet opening 5 in liquid inlet pipe 3, make the inner chamber distending of rubber hose 7, be attached on the inwall of groove 9, inlet opening 5 and liquid outlet opening 6 are interconnected, liquid flows out as shown in Figure 4, Figure 5 through liquid outlet opening 6 from drain pipe 4, and in figure, arrow is depicted as the glide path of liquid, and namely aeroelasticity switching flow valve is in the state of unlatching.
