Abstract
The utility model relates to an on-off valve, comprising a valve body, a valve cover, a moving piece, a left and a right fixing pieces, a left and a right sealing rings and a moving piece handle. The moving piece and the fixing pieces form end face sealing, and the fixing pieces and the valve body form radial sealing. The end face seal guarantees no leakage in running for 5000-8000 hours (the rotary speed is 3000 circle / minute) under the condition of the dynamic sealing. The end face sealing is applied to the on-off valve, which guarantees the reliable sealing. The moving piece handle rotates 90 DEG, and then the connection and the disconnection of the on-off valve are realized. The action is fast, and the connection and the disconnection are connected.
Description
The utility model relates to a kind of on-off valve.
Gate valve and ball valve are two kinds of the most frequently used on-off valves, and three relatively distinct issues are arranged in the use: the one, and the sealing surface of spool and valve seat often loses seal action because of wearing and tearing; The 2nd, valve rod is easy to wearing and tearing with the packing seal at valve rod hole place, and loses seal action, and the seal break-off at this two place all can cause dielectric leakage; The 3rd, the lifting of spool or decline are to realize with the spiral motion between the valve body by valve rod, so the unlatching of valve or close and need the long period, and break-make is not clear-cut.
It is firm that the purpose of this utility model provides a kind of sealing, the on-off valve that break-make is clear-cut.
This on-off valve is by valve body, valve gap, moving plate, left side stator, right stator, left side seal ring, right seal ring and moving plate handle are formed, moving plate wherein, be respectively equipped with pod apertures on left side stator and the right stator, and be sleeved on together with left seal ring and right seal ring in the stepped valve opening of valve body, left side seal ring and right seal ring are separately positioned on the outside of left stator and right stator, moving plate is arranged on left stator with between the right stator, left side stator and the circumferential position of right stator in valve opening are by being arranged on the valve body, and the interior locating stud of the cotter way that is inserted into left stator and right stator limits, the moving plate handle radially is provided with along moving plate, and limit the logical of moving plate handle by the handle groove on the valve body, disconnected position, valve gap is threaded with valve body, by moving axially of valve gap, with left seal ring, left side stator, moving plate, right stator and right seal ring surface of contact each other compress, and form left stator, right stator with the radial seal between the valve opening and moving plate with left stator, end face seal between the right stator.
Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: structural drawing of the present utility model;
Fig. 2: A-A sectional view;
Fig. 3: the front view of stator.
As shown in the figure: this on-off valve is by valve body 1, valve gap 2, moving plate 3, left side stator 4, right stator 5, left side seal ring 6, right seal ring 7 and moving plate handle 8 are formed, wherein moving plate 3, be respectively equipped with pod apertures 9 on left side stator 4 and the right stator 5,10,11, and be sleeved on together in the stepped valve opening 12 of valve body 1 with left seal ring 6 and right seal ring 7, left side seal ring 6 and right seal ring 7 are separately positioned on the outside of left stator 4 and right stator 5, moving plate 3 is arranged on left stator 4 with between the right stator 5, left side stator 4 and the circumferential position of right stator 5 in valve opening 12 are by being arranged on the valve body 1, and be inserted into the cotter way 13 of left stator 4 and right stator 5, locating stud 15 in 14 limits, moving plate handle 8 radially is provided with along moving plate 3, and limit the logical of moving plate handle 8 by the handle groove on the valve body 1 16, disconnected position, valve gap 2 is threaded with valve body 1, by moving axially of valve gap 2, with left seal ring 6, left side stator 4, moving plate 3, right stator 5 and right seal ring 7 surface of contact to each other compress, and form left stator 4, right stator 5 with the radial seal between the valve opening 12 and moving plate 3 with left stator 4, end face seal between the right stator 5.Pod apertures 9,10,11 on moving plate 3, left stator 4 and the right stator 5 generally is symmetrical arranged, flow during with the increase conducting, make moving plate 3, left stator 4 and right fixed 5 material and should have high hardness and high wear resistance, usually select cemented carbide or stupalith for use, and the end face of moving plate 3, left stator 4 and right stator 5 should carry out mirror finishing, to guarantee the reliability of end face seal.Moving plate handle 8 is fastenedly connected with moving plate 3 usually, consider the difficulty of material forming processing such as pottery, can be at the periphery suit of moving plate 3 with valve opening 12 collar 17 movingly, moving plate handle 8 is by being threaded and inserting the location and installation that realizes self in the handle hole 18 of moving plate 3 and with the interlock of moving plate 3 with collar 17.Normally 90 ° of the rotation angles of moving plate 3 switching positions, the angle of circumference of the handle groove 16 on the valve body 1 also should be herewith corresponding, in order to guarantee the cleaning of handle groove 16, can be on handle groove 16 topped with valve body 1 movingly and in company with the dust ring 19 of moving plate handle 8 actions.Left side seal ring 6 and right seal ring 7 should have elasticity, select the O RunddichtringO usually for use.As a kind of on-off valve, on valve body 1 and the valve gap 2 the connecting tube screw thread that is connected with other pipe fitting should be set also.
Formed end face seal can guarantee that under the condition of motive sealing moving 5000～8000 hours does not leak (when rotating speed is 3000 rev/mins) between the moving plate of said structure and the stator, in view of the above, this end face seal is applied in the on-off valve, can guarantee definitely that sealing is reliable, in addition, realize the switching of this on-off valve, the moving plate handle only must be done 90 ° rotation, action can accomplish that rapidly break-make is also just clear-cut.
