Abstract
The utility model relates to a valve, in particular to a clutch type self-locking valve, which comprises a valve column, which comprises an upper valve column (1), a lower valve column (2), a clutch joint (3) and a clutch spring (4), the clutch joint is arranged in a via hole of the upper valve column, and the lower end of the clutch joint is arranged on the upper end of the clutch spring in a clutch spring hole (7) of the lower valve column and is located on a dividing line between the upper valve column and the lower valve column. Because the valve column of the utility model uses a clutch type structure, thereby overcoming the defects that a hand wheel on the valve column of a prior valve with a lock is easy to be forcibly rotated to damage the valve column, and the utility model has the advantages of simple structure, novel design, low manufacture cost, and convenient operation and the like. Because the effect of the clutch spring in a normal state, the upper valve column and the lower valve column are separated, although the hand wheel on the valve is randomly rotated, the valve is not opened, the valve column is not damaged, and the functions of the normal opening and closing of the valve is not capable of being affected.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of clutch type Self-locking valve.
Background technique
For strengthening the water supply management of water supply industry, strict control water source, using water wisely, prevent valve from arbitrarily opening and closing and cause water resource waste, steal water and water situation such as do not pay dues and take place, someone has designed Valve with lock, and it is a dress lock on valve, and valve rod is by spline after the locking, its deficiency is the Yi Beiren handwheel on the changeover valve and valve rod is destroyed by force, causes valve normally to open and close.
Technology contents
The purpose of this utility model is to overcome above the deficiencies in the prior art part and a kind of clutch type Self-locking valve is provided.
The technical solution of the utility model is: the clutch type Self-locking valve includes valve rod, valve rod is the clutch type structure, it comprises valve rod, lower valve column, can make, clutch sub and clutch spring that lower valve column separates or engages, be useful on the through hole that clutch sub is installed on the last valve rod, rach slot is arranged at the bottom of through hole, the clutch spring eye is arranged on the lower valve column, in the clutch spring eye rach slot is arranged, tooth bar is arranged at the clutch sub bottom, the clutch spring is installed in the clutch spring eye of lower valve column, clutch sub is installed in the through hole of valve rod, and its lower end contacts with the clutch spring and is positioned at, on the separatrix of lower valve column.
The utility model is owing to adopt as above design, compared with prior art, because valve rod adopts the clutch type structure, overcome existing Valve with lock and easily gone into the deficiency of rotating the handwheel on the valve rod by force and valve rod being destroyed, have simple in structure, novel in design, fabricating cost is low, advantage such as easy to use, during normality because the effect of clutch spring, upper and lower valve rod separates, handwheel on any changeover valve, all can't opening/shutting valve, and valve rod can not be subjected to any damage, and the normal keying function of valve can not be affected.
Description of drawings
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the sectional drawing of last valve rod;
Accompanying drawing 3 is the sectional drawing of lower valve column.
Embodiment
Embodiment: as shown in drawings, the clutch type Self-locking valve includes valve rod, valve rod is by last valve rod (1), lower valve column (2), clutch sub (3) and clutch spring (4) are formed, be useful on the through hole (5) that clutch sub (4) is installed on the last valve rod (1), rach slot (6) is arranged at the bottom of through hole (5), clutch spring eye (7) is arranged on the lower valve column (2), rach slot (8) is arranged in the clutch spring eye (7), tooth bar (9) is arranged at clutch sub (3) bottom, and clutch spring (4) is installed in the clutch spring eye (7), and clutch sub (3) is installed in the through hole (5) of valve rod (1), the last end in contact of its lower end and clutch spring (4) also is positioned at, on the separatrix of lower valve column.
When need open and close the utility model, can will be installed in the interior clutch sub (3) of valve rod (1) to pressing down, make clutch spring (4) compression, then rach slot (8) engagement in the part tooth bar (9) of clutch sub (3) bottom and the lower valve column clutch spring eye (7), and upper and lower valve rod is engaged, rotation hand wheel (11) is able to turn on or off the utility model again.In the time need not opening and closing the utility model, only need unclamp clutch sub (3) resets clutch spring (4), then the tooth bar (9) of clutch sub (3) bottom is all got back under the effect of clutch spring (4) in the through hole (5) of valve rod (1), and upper and lower valve rod is separated.At this moment, rotation hand wheel all can't open and close the utility model in any case.
Claims (1)
1, a kind of clutch type Self-locking valve, it includes valve rod, valve rod is the clutch type structure, it comprises valve rod and lower valve column, it is characterized in that also including and to make, clutch sub and clutch spring that lower valve column separates or engages, be useful on the through hole that clutch sub is installed on the last valve rod, rach slot is arranged at the bottom of through hole, the clutch spring eye is arranged on the lower valve column, in the clutch spring eye rach slot is arranged, tooth bar is arranged at the clutch sub bottom, and the clutch spring is installed in the clutch spring eye of lower valve column, clutch sub is installed in the through hole of valve rod, and its lower end contacts with the clutch spring and is positioned at, on the separatrix of lower valve column.
