Abstract
The utility model relates to the machinery technical field of an antimagnetic and anti-leakage cutoff valve, which comprises a T-shaped shell body, a gas or liquid inlet cavity A and a gas or liquid outlet cavity B which are the same axial lead and a controlling cavity C which is perpendicularly equipped on the axial cord of the gas or liquid inlet cavity A and the gas or liquid outlet cavity B. A bell crank which is connected with a generator assembly is covered on the shutter which has a certain angle with the surface of valve core assembly, when the shutter can be opened. This utility model is characterized in that firstly fluid medium and the generator assembly are divided to avoid contamination and corrosion of the generator assembly, secondly steel jacket is used to shield the generator to resist the destroy of the external strong magnetic field, and third loss of fluid pressure of the valve with high reliability is small.
Description
The utility model belongs to field of mechanical technique, relates to further that a kind of and pipeline are matching used to have an antimagnetic and anti-controllable stop valve of letting out function.
Stop valve mainly is a kind of valve that is used for control gaseous, fluid pipeline open and close.Controllable stop valve commonly used at present often exists gas or leaked liquid owing to there is defective on Seal Design in the using process, and the phenomenon of contaminating impurity in gas and the liquid and corrosion driving mechanism.The driving system structure complexity of Chang Yong controllable stop valve in addition, thus cause power consumption big.Existing controllable stop valve passivity magnetic force damage capability is arranged again, influence the motor proper functioning behind the chance high magnetic fields, bring inconvenience for actual the use.
The control valve that the purpose of this utility model is to provide a kind of simple in structure, good airproof performance, reliability height, power consumption is low and have anti-magnetic and anti-leak.
In order to realize above-mentioned purpose, solution of the present utility model is: the antimagnetic anti-housing of letting out controllable stop valve is the T type, air inlet (liquid) chamber A and (liquid) chamber B coaxial inner conductor of giving vent to anger, electric machine assembly places control chamber C, and control chamber C is perpendicular to the axis of air inlet (liquid) chamber A with (liquid) the chamber B that gives vent to anger.Electric machine assembly sealed and the shielding, the rocker sleeve that is connected with electric machine assembly on the cover board, when cover plate is opened and the mangetic core assembly face at an angle.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is an overall structure sectional drawing of the present utility model.
Structure of the present utility model: form by air inlet (liquid) the chamber A of T shell body 1, give vent to anger (liquid) chamber B and control chamber C.Air inlet (liquid) chamber A and (liquid) chamber B coaxial inner conductor of giving vent to anger, this structure can reduce the pressure loss of fluid, and control chamber C is perpendicular to the axis of air inlet (liquid) chamber A with (liquid) the chamber B that gives vent to anger.Electric machine assembly 14 sealing is arranged among the control chamber C, is flush-mounted in the circular hole on the cover plate 3 with the rocking bar 2 of suit on the electric machine assembly 14, and the other end of cover plate 3 is connected with mangetic core assembly 4 usefulness hinges.The motion of electric machine assembly 14 drives rocking bar and rotates, and rotates thereby drive cover plate 3, realizes the open and close of valve, and opening angle is 45 °-75 °.Mangetic core assembly 4 is installed in (liquid) chamber B end of giving vent to anger of housing 1, between mangetic core assembly 4 and housing 1 seal ring 10 is housed, and with jump ring 5 mangetic core assembly 4 is fixed on the housing 1, is used to the leakage that prevents that cavity is interior.Nut 9 is enclosed within the outlet of mangetic core assembly 4, and is fixed on the mangetic core assembly 4 by left-handed nut 7, is used for pipeline and connects.Seal ring 8 is installed on mangetic core assembly 4 ports, be used to prevent and connected pipe between leakage is arranged.Cover plate 6 is used for the sealed electric-motor guide line at the bottom of placing valve.Antimagnetic steel bushing 16 is installed on valve body C chamber and is set on the electric machine assembly 14, is used for the interference of strong magnetic field proof to motor.Between antimagnetic steel bushing 16 end faces and electric machine assembly 14, seal ring 11 is housed, prevents from from control chamber C, to leak.A seal ring 13 is housed and pressing plate 12 is compressed by circlip 17 at the other end of antimagnetic steel bushing 16, to prevent the axial displacement of motor.At the sticking panel 15 of the port of control chamber C, to play attractive in appearance and the sign effect.
The antimagnetic anti-automatic control that controllable stop valve is mainly used in gas on the pipeline (liquid) body of letting out of this kind, can with the supporting use of IC-card gas meter.
The utlity model has following distinguishing feature: 1. gas medium fully and electric machine assembly every Open, can prevent effectively that gas (liquid) body medium is to pollution and the corrosion of electric machine assembly. 2. adopt The steel bushing shield electric machine can be resisted extraneous high-intensity magnetic field to the destruction of valve. 3. the stream of this valve The body pressure loss is little, the reliability height.
