Abstract
The utility model discloses a magnetic-force screw-up type check valve, comprising a valve body, a valve plate, an armature iron and a permanent magnet. When medium passes through the valve body, the valve plate is screwed up to be attracted to be suspended on the conducting magnetic armature iron at the inner wall of the valve body under the action of the magnetic force of the permanent magnet. The magnetic force of the permanent magnet is a little less than the gravity of the valve plate; when no medium passes through, the valve plate disengages from the armature iron via the own gravity of the valve plate to automatically drop down, and thus the valve of the utility model is closed. Compared with the original check valve, the check valve of the utility model is characterized in that the wastage, of the kinetic energy of the medium, which is generated by that the valve plate is suspended is eliminated, obtaining the efficiency of low resistance and energy saving. The utility model can be used for check valves with various specification, high, middle and low pressure and high, middle and low temperature.
Description
The utility model belongs to valve, and particularly a kind of improved magnetically controlled safety check flow resistance is low, and tangible energy-conservation effect is arranged.
Existing safety check when medium passes through valve body, must have a masterpiece to be used on the valve plate, keeps valve plate to hang, because valve is distinguished the weight of self, overcomes this weight, then produces the medium kinetic energy loss.
Task of the present utility model provides the energy-conservation safety check of a kind of improved low-resistance.Valve plate is eliminated valve plate and has been hanged the medium kinetic energy loss that produces outstanding the suction on the armature of valve interior wall upper end under the magnetic force of permanent magnet, reaches the energy-conservation effect of low-resistance.
Task of the present utility model is finished as follows: permanent magnet is loaded on the valve plate rear portion, and armature is installed on the valve interior wall upper end.Permanent magnet magnetic force is slightly less than whole valve plate gravity.When medium passes through, in pressure medium effect lower valve plate spin-up, the outstanding suction on armature; No medium by the time, valve plate breaks away from armature by himself gravity and falls automatically, throttle down reaches and prevents medium refluence function.
Prominent features of the present utility model is: flow resistance is little, the medium kinetic energy loss is low, has tangible energy-conservation effect.Be applicable to all size senior middle school low temperature, senior middle school's low pressure check valves.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is concrete structure figure of the present utility model.
With reference to Fig. 1, the utility model is by valve body 3, valve plate 4, permanent magnet 1, armature 2 is formed, and wherein permanent magnet 1 is fixed on the valve plate 4, and armature 2 is installed on the valve body 3, when MEDIA FLOW is crossed valve body 3, the pressure of medium fluid is opened valve plate 4, and the permanent magnet 1 on the valve plate 4 is adsorbed in the armature 2 of valve body 3, because magnetic force has reduced the kinetic energy loss of medium, when there not being MEDIA FLOW out-of-date, owing to the weight of valve plate self overcomes the magnetic force original position throttle down that falls back.
