Abstract
The utility model relates to a clutch type leakage-free valve with a lock, which comprises a handle, a valve cover, a valve rod, a valve seat, and a valve lock, wherein, the valve seat is provided with an inlet and an outlet paths which are mutually communicated and an installing path of the valve rod; the valve rod path and the inlet and the outlet paths are separated by a sealing diaphragm; the valve rod which passes through the valve cover is connected with the handle, and the valve rod is in a clutch type structure. The utility model is characterized in that the valve rod is composed of an upper valve rod, a lower valve rod, and a clutch gear which are mutually matched, and the clutch gear is sheathed on the valve rod and is engaged with a lock core of the valve lock. The clutch type leakage-free valve with a lock which can not change overflow flow quantity of the valve not only can avoid leakage, but also can cause the valve to be like an insurance lock. A valve is opened by a key, and the utility model is safe and is for the convenience of operation.
Description
Technical field: the utility model relates to a kind of valve, especially disengaging type ne-leakage valve with lock.
Background technology: valve is used for regulating flow and the direction with the water of controlling plumbing fixtures, is pipe network normal management, repairing, the indispensable equipment of maintenance.In the long-term evolution of water supply industry, by constantly improving and upgrading, the quality and the function of valve are greatly improved, but, valve leaks and anyone arbitrarily management of the formula out of control of Open valve, brings bigger influence to water undertaking from productive costs and network security management.In order to strengthen the management of supplying water, using water wisely, prevent valve from arbitrarily opening and closing and the generation of phenomenon such as cause that waste, pilferage water and water are not paid dues, someone has designed Valve with lock, wherein also has the disengaging type Valve with lock, it mainly is the valve rod that adopts the disengaging type structure, promptly is made up of last valve rod, lower valve column and the clutch joint that can make upper and lower valve rod separate and unite under the effect of lock core that is installed in therebetween.It is simple in structure, but disengaging performance is subjected to the valve seepage in actual use and the spontaneous corrosion influence is bigger, fails to consider the influence of valve seepage.And my ZL00232364.8 patent has only solved the leakage problems of valve, can not prevent the random unlatching of valve.
Summary of the invention: the problem of the utility model in order to solve the valve seepage and can to open arbitrarily, a kind of disengaging type ne-leakage valve with lock is proposed on the basis of former ne-leakage valve, include handle, valve cover, valve rod, valve seat and valve lock, described valve seat has the import and export passage and the valve rod that are interconnected passage is installed, described valve stem passage separates by seal dissepiment with the import and export passage, and described valve rod passes described valve cover catcher handle; Described valve rod is the disengaging type structure, it is characterized in that: described valve rod is made up of the upper valve rod that cooperatively interacts, lower valve rod and clutch gear; Described clutch gear be socketed on the described valve rod and with the lock core engagement of described valve lock.This valve does not change the valve aperture water flow, both can stop the valve seepage, can make valve as insurance lock again, and by a key operated valve, promptly safety is convenient to operation again.
Description of drawings: Fig. 1 is the utility model structural representation.
The specific embodiment: as shown in Figure 1, this disengaging type ne-leakage valve with lock includes handle 1, valve cover 2, valve rod 3, valve seat 5 and valve lock 4, and lock core 9 is arranged on the valve lock 4; Valve seat 5 has the import and export passage 6 and the valve rod that are interconnected path 10 is installed, and valve stem passage 10 separates by seal dissepiment 7 with import and export passage 6, and valve cover 2 catcher handles 1 are passed in valve rod 3 upper ends; Valve rod 3 is the disengaging type structure, by the upper valve rod that cooperatively interacts 15 and and lower valve rod 11 and the clutch gear 12 that is socketed in upper and lower valve rod joint form; Clutch gear 12 meshes with the lock core 9 of valve lock 4.Upper valve rod 15 is to be connected by spline with lower valve rod 11, and there is internal splined hole 13 upper valve rod 15 lower ends, and the lower end is provided with boss 14; Lower valve rod 10 the first half are spline structure, cooperate with the internal splined hole 13 of upper valve rod 15, and the latter half is a helicitic texture, and end face is by pad 8 pinch-off seal barrier films 7.Clutch gear 12 is socketed on the lower valve rod 11, with lower valve rod 11 spline fitted, and between last lower valve rod.Lock core 9 is radially installed, and mate is half-cylindrical, and the teeth groove with the clutch gear coupling is arranged on cambered surface.During valve-off, rotational lock core 9 and clutch gear 12 engagements, clutch gear 12 make upper valve rod 15 and lower valve rod 11 throw off along with the rotation of lock core 9 is moved vertically, at this moment, in any case rotary handle 1 all can't Open valve, also can not damage valve rod 3 simultaneously.During Open valve, rotational lock core 9 makes lock core 9 and clutch gear 12 jump out of meshs, and clutch gear 12 falls, upper valve rod 15 and lower valve rod 11 spline fitted, and this moment, turning handle 1 drove upper and lower valve rod work, reached the purpose of Open valve.
