Description
Technical field
The present invention relates to a kind of flow control valve, specifically a kind of new type explosion proof low noise flow control valve.
Background technique
Modulating valve is equipment important in the industrial pipeline feeding devices such as oil refining, chemical industry.Modulating valve is made up of actuator and valve part two-part.Actuator is the drive unit of modulating valve, and traditional actuator is that motor drives, and it produces corresponding thrust by the size of signal pressure, makes push rod produce corresponding displacement, thus the action of band movable valve plug; Valve part is the adjustment portion of modulating valve, direct and medium contact, by the displacement of actuator's push rod, changes the orifice size of modulating valve, reaches the object of adjustment, and it is also the main occurring source of noise simultaneously.Noise pollution has become one of universally acknowledged 4 large pollution sources, and each state all drops into huge fund noise control, and people have higher requirement to Noise measarement.Modulating valve is usually the noise source in pipe-line system, when pressure drops to certain critical value, easily causes air pocket, cavitation phenomenon, and with flow noise and vibration.Modulating valve flow passage structure affects the key factor that modulating valve produces noise; Therefore, be necessary to the research of regulating valve structure.For the pipeline transporting explosives, inflammable items, if there is leakage, or under modulating valve is operated in inflammable and explosive environment, motorized adjustment regulating and controlling valve not easily uses, and adopts the control mode of safety anti-explosive to become inevitable.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of new type explosion proof low noise flow control valve; There is explosion prevention function and noise is low, structure simply, regulable control not easy to wear, easy.
The present invention realizes with following technological scheme: a kind of new type explosion proof low noise flow control valve, comprises hydraulic cylinder and is fixed on the hollow cylinder promotion cylinder in hydraulic cylinder; The two ends of hydraulic cylinder are arranged with oil hydraulic cylinder cavity, are provided with flanged pipe I in the oil hydraulic cylinder cavity of one end, are provided with flanged pipe II in the oil hydraulic cylinder cavity of the other end; Described flanged pipe I one end is flange I, and the other end is plunger I, and plunger I sealing is arranged in the oil hydraulic cylinder cavity of hydraulic cylinder one end, and plunger I is provided with the hydraulic oil be communicated with this end oil hydraulic cylinder cavity and imports and exports I; Described flanged pipe I one end is flange II, and the other end is plunger II, and plunger II sealing is arranged in the oil hydraulic cylinder cavity of the hydraulic cylinder the other end, and plunger II is provided with the hydraulic oil be communicated with this end oil hydraulic cylinder cavity and imports and exports II; One end that hollow cylinder promotes cylinder is sleeved in flanged pipe I through plunger I, and the other end is sleeved in flanged pipe II through plunger II, and hollow cylinder promotes cylinder and can move in flanged pipe I and flanged pipe II; The conical vortex rolling flat spring that two symmetrical conical vortex rolling springs are formed is installed in flanged pipe II, be fixed together with connection set between two conical vortex rolling springs, one end that the conical vortex rolling flat spring left side is large and hollow cylinder promote cylinder end face and are fixed together, and one end that the right is large and flanged pipe II inwall are fixed together.
The invention has the beneficial effects as follows: there is explosion prevention function and noise is low, structure simply, regulable control not easy to wear, easy.

Embodiment
As depicted in figs. 1 and 2, a kind of new type explosion proof low noise flow control valve has a hydraulic cylinder 1 and the hollow cylinder be fixed in hydraulic cylinder 1 to promote cylinder 5; The two ends of hydraulic cylinder 1 are arranged with oil hydraulic cylinder cavity 1.1, are provided with flanged pipe I 2 in the oil hydraulic cylinder cavity of one end, are provided with flanged pipe II 3 in the oil hydraulic cylinder cavity of the other end; Described flanged pipe I one end is flange I 2.3, and the other end is plunger I 2.1, and plunger I 2.1 sealing is arranged in the oil hydraulic cylinder cavity of hydraulic cylinder one end, and plunger I 2.1 is provided with the hydraulic oil be communicated with this end oil hydraulic cylinder cavity and imports and exports I 2.2; Described flanged pipe I one end is flange II 3.3, and the other end is plunger II 3.1, and plunger II 3.1 sealing is arranged in the oil hydraulic cylinder cavity of the hydraulic cylinder the other end, and plunger II 3.1 is provided with the hydraulic oil be communicated with this end oil hydraulic cylinder cavity and imports and exports II 3.2; One end that hollow cylinder promotes cylinder 5 is sleeved in flanged pipe I 2 through plunger I 2.1, and the other end is sleeved in flanged pipe II 3 through plunger II 3.1, and hollow cylinder promotes cylinder 5 and can move in flanged pipe I 2 and flanged pipe II 3; The conical vortex rolling flat spring 4 that two symmetrical conical vortex rolling springs are formed is installed in flanged pipe II 3, be fixed together with connection set 4.1 between two conical vortex rolling springs, one end that conical vortex rolling flat spring 4 left side is large and hollow cylinder promote cylinder 5 end face and are fixed together, and one end that the right is large and flanged pipe II 3 inwall are fixed together.
In the present embodiment, described hydraulic cylinder 1 is circular cylinder body, and on the end wall at the two ends of circular cylinder body, symmetry has annular groove, and annular groove forms oil hydraulic cylinder cavity; Described connection set adopts ball.
Working procedure: flanged pipe I 2 and flanged pipe II 3 are connected and fixed with conveying pipe main body, assembly flange pipe 2 I and flanged pipe 3 II time, many-sided installation precision between flanged pipe I 2 and flanged pipe II 3 must be ensured.When hydraulic oil from hydraulic oil import and export I 2.22.2 enter oil hydraulic cylinder cavity 1.1 left chamber time, hydraulic oil promotes hydraulic cylinder 1 and drives hollow cylinder promotion cylinder 5 to move right, and then compression taper scroll-type flat spring 4, gap between conical vortex rolling flat spring 4 is diminished, thus minimizing through-current capacity, the hydraulic oil in the right chamber of oil hydraulic cylinder cavity 1.1 is imported and exported II 3.2 from hydraulic oil and is flowed back to fuel tank; On the contrary, when hydraulic oil imports and exports II 3.2 inflow oil hydraulic cylinder cavity body 1.1 right chamber from hydraulic oil, promoting hydraulic cylinder 1 drives hollow cylinder to promote cylinder 5 to left movement, and then stretching conical vortex rolling flat spring 4, the gap between conical vortex rolling flat spring 4 is made to become large, thus increase through-current capacity, the hydraulic oil on the left of hydraulic cylinder cavity 1.1 flows back to fuel tank from import and export 2.2; Because this system adopts hydraulic driving mode to carry out regulating the gap size of taper flat spring 4, thus there is explosion-proof low-noise characteristic.
