Abstract

The utility model relates to a valve which is provided with changeable open and close directions and is capable of altering open or close state with the valve core rotated at 90 DEG. A shift block is arranged on a valve pole and a spacing sheet is sheathed in the shift block with changeable angles. A stop block which is fixed on a valve cap is capable of blocking the spacing sheet to cause the spacing sheet to rotate within a scope of 90 DEG at both ends. The spacing sheet is sheathed on the shift block of the valve pole and provides a leftward rotating or leftward rotating motion stroke, which is capable of altering the valve into a valve which is opened by rotating leftward or rightward. The utility model needs no other spare parts and customers can change the rotating directions of the opening and the closing of the valve according to the installing position or habitual usage.

Description

A kind of valve of convertible switch direction

The utility model relates to pipeline valve, and particularly a kind of handle rotates the 90 ° of valves that just can open or close.

The sense of rotation of its valve rod was unique when existing various valve (or water tap) was opened or closed.For the valve of shaft-like handles such as ball valve and Valve with ceramic core, because the movement locus of handle will occupy than large space, its mounting point often is subjected near the restriction of obstacles such as pipeline wall, the valve, and is not easy to the operation of opening, closing.

The purpose of the utility model is the valve that provides a kind of convertible unlatching or close sense of rotation, to reduce the restriction that use valve the mounting point.

Valve described in the utility model, constitute by valve body, spool, valve rod, handle, a multangular shifting block is arranged on valve rod, after being arranged, the convertible angle of banking stop is enclosed within on the shifting block, and banking stop is enclosed within that both can not relatively rotate on the shifting block, and there is a lug at the edge of banking stop, but fixing two ends stop the block of banking stop lug motion on the valve gap, rotation angle with the restriction banking stop is 90 °, and the rotation angle that promptly limits valve rod is 90 °.

Because the no matter left-handed or dextrorotation of the spool of ball valve and Valve with ceramic core just can change the state that opens or closes as long as change 90 °.And valve described in the utility model, the convertible angle of its banking stop is enclosed within on the shifting block of valve rod, and this valve of movement travel of reserving left-handed or dextrorotation as required just becomes the valve of left-handed unlatching or dextrorotation unlatching.Described valve does not only need to add in addition the rotation direction of accessory with regard to convertible switch by the setting angle that changes banking stop, can adjust the setting angle of banking stop voluntarily when being convenient to the user and being restricted in the mounting point, and change its rotation direction.

The partial sectional perspective view of a kind of described valve of Fig. 1

The spool three-dimensional exploded view of Fig. 2 Valve with ceramic core

Fig. 3 banking stop is in the stereogram of left-handed closed condition

Fig. 4 banking stop is in the stereogram of dextrorotation closed condition

The valve of ceramic valve core as shown in Figure 1 is in opening state.Drive ceramic moving plate 8 by valve rod 4 and rotate relative to ceramic stator 7, no matter left-handed, dextrorotation, moving plate just becomes closed condition for 90 ° from the state commentaries on classics of Fig. 1.Handle 5 links to each other with the spline of valve rod 4 top sections.As Fig. 2 a multangular shifting block 9 is arranged on valve rod 4.Illustrated shifting block 9 is the quadrilateral of four corner angle, also Hexagon, Octagon or spline.Have on the banking stop 2 and shifting block 9 corresponding corner angle, and convertible angle is enclosed within on the shifting block 9.Flexible snap ring 3 is enclosed within on the valve rod 4, comes off to prevent banking stop 2.A lug 10 is arranged on the banking stop, the fixing block 6 that can stop that banking stop upper lug 10 is rotated on the valve gap 1 at two ends, the rotation that also limits valve rod 4 with restriction banking stop 2 simultaneously is 90 °.If banking stop 2 is enclosed within on the shifting block 9 by Fig. 3 state, this valve is left-handed closing; Be enclosed within on the shifting block 9 by Fig. 4 state, valve is that dextrorotation is closed.

Should point out that what present embodiment provided is the ceramic core valve, but described product structure is suitable for also to ball valve.

Claims

1, a kind of valve of convertible switch direction, by valve body, spool, valve rod (4), handle (6) constitute, it is characterized in that a multangular shifting block (9) is arranged on valve rod (4), have the convertible angle of banking stop (2) to be with on the shifting block (9), and banking stop (2) is enclosed within shifting block (9), and upward both can not relatively rotate, there is a lug (10) at the edge of banking stop (2), valve gap (1) but go up the block (6) that fixing two ends stop banking stop lug (10) motion.
