Abstract
The utility model relates to a fluid valve which realizes isolation transmitting mode and finishes the opening and closing motion through magnetic force. The utility model arranges the valve motion components, which finish the valve opening and closing like the magnetic rotor of the valve body, the gland bush, the valve body screw, and the valve platform in an airtight valve cavity. An operational magnetic rotating ring is cased outside the valve pipe. The utility model realizes the mechanical isolation control of the valve through magnetic force, so as to make the valve pipe obdurate completely.
Description
Affiliated technical field
The utility model relates to a kind of Fluid valve, particularly a kind of screw-pushing type full closed novel valve that utilizes magnetic force to realize the non-contact transmission.
Technical background
Existing valve, generally adopt to change and realize what the switch of convection cell was controlled by the mode of section pipeline area of passage, and the operating grip that changes valve body and controlled pipeline overflow section relative position all runs through valve housing by connecting rod and valve body is connected, connecting rod and valve housing through part need sealing, promptly increase the valve manufacture difficulty, Sealing is very easily wearing and tearing again, have shortened the bulk life time of valve greatly.
Summary of the invention
In order to overcome the deficiency that existing valve operation connecting rod need run through valve housing, the utility model provides a kind of switch motion valve body and external force operative section to place respectively and is cut the inside and outside of keyholed back plate road, does not have any mechanical link therebetween and realizes that by magnetic force the contactless isolation power transmission between external force operative section and the action valve body finishes the novel full closed valve that opening and closing are moved.
The technical scheme in the invention for solving the technical problem is: valve body action magnet rotor is installed in valve cavity, valve body action magnet rotor can change the relative position of self and sealing gasket and valve gallery when rotating, in order to realize the open and close of valve: in the valve tube outside, be with the operation magnetic rotation ring that can on valve tube, freely rotate, like this, when the operation magnetic rotation ring outside external force makes valve tube rotates, because the effect of magnetic force, valve body action magnet rotor in the valve cavity can rotate thereupon, finishes the open and close and the action of control inflow-rate of water turbine of valve.Having reached valve tube is kept perfectly airtight and effectively realizes the purpose of switch motion.
The beneficial effects of the utility model are: the valve members such as valve body action magnet rotor, sealing gasket of finishing the open and close of valve all are enclosed in the valve cavity, and switching manipulation partly is placed on outside the valve tube, need not to run through the operating device of valve tube, make whole valve good leak tightness, make simply long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front section view of Fig. 1.
Reference character: outflow tube (1), operation magnetic rotation ring (2), valve tube (3), influent stream pipe (4), influent stream tube cavity (5), valve cavity (6), valve body action magnet rotor (7), sealing gasket (8), valve gallery (9), valve body screw rod (10), flowing hole (11), valve nut (12), outflow tube inner chamber (13).
Embodiment
Below in conjunction with accompanying drawing the utility model is described further
Operation magnetic rotation ring (2) is enclosed within valve tube (3) and goes up also and can rotate around valve tube (3).Valve body action magnet rotor (7) is installed in valve cavity (6), and magnetic pole is in its outer rim and and generation magnetic force mutual effect relative with operation magnetic rotation ring internal magnetic pole.Like this, when external force was rotated operation magnetic rotation ring (2), valve body action magnet rotor also rotated thereupon.Valve body action magnet rotor (7) is connected with valve body screw rod (10) and can rotates; Valve nut (12) is installed in outflow tube inner chamber (13), valve nut (12) is connected with the inwall of outflow tube (1), because valve body screw rod (10) is meshed with valve nut (12), so, when valve body action magnet rotor (7) drives valve body screw rod (10) rotation, valve body action magnet rotor (7) generation motion up or down be will make, thereby action magnet rotor (7) bottom surface of valve body and the relative position between the valve gallery (9) changed.Sealing gasket (8) is posted in bottom surface at valve body action magnet rotor (7), and like this, when valve body action magnet rotor (7) rotated descending and make sealing gasket (8) be pressed on the valve gallery (9), fluid passage was blocked, and valve is closed condition.At this moment, the fluid that enters influent stream tube cavity (5) from influent stream pipe (4) can enter in the valve cavity (6), and can not enter outflow tube inner chamber (13), has realized the shutoff of convection cell; When valve body action magnet rotor (7) rotates up and drives sealing gasket (8) disengaging valve gallery (9), fluid passage is opened, valve is opening state, fluid in the valve cavity (6) will enter outflow tube inner chamber (13) by the flowing hole (11) that is arranged on the valve nut (12), from outflow tube (1), flow out, realized the open-minded of convection cell.The distance of the distance of sealing gasket (8) and valve gallery (9) is determining the size of valve overflow section to change this distance, can realize the adjusting control of convection cell inflow-rate of water turbine.
Claims (2)
1, the pusher valve of full closed magnetic drving sprial mainly is made up of operation magnetic rotation ring (2), valve tube (3), valve body action magnet rotor (7), sealing gasket (8) and valve body screw rod (10) etc., it is characterized in that: valve body action magnet rotor (7) is connected with valve screw rod (10), and be installed in the valve cavity (6), operation magnetic rotation ring (2) is enclosed within the outside of valve tube (3).
2, full closed magnetic drving sprial force pushing type valve according to claim 1 is characterized in that described operation magnetic rotation ring (2) can be around valve tube (3) rotation, and the outer within it both sides of the magnetic pole of operation magnetic rotation ring (2) distribute.
