The angle stop valve comprises a valve body, wherein a valve bonnet is arranged on the valve body, mutually perpendicular passages and a valve clack matched with the passages are arranged in the valve body, a valve seat matched with the valve clack is arranged in the valve body, a connecting passage communicated with the passages is arranged in the valve seat, a connecting block is arranged at the lower end of the valve clack, the sum of the height of the connecting block and the valve clack is larger than the height of the valve seat, a chromium alloy block is arranged on the valve clack, one end of a valve rod stretches out of a nut on the valve bonnet and is connected with a handle, the nut and the valve bonnet are connected through fixing screws, an annular lubricating passage is arranged in the nut, an oil inlet communicated with the annular lubricating passage is formed in the nut, and an oil inlet nozzle communicated with the oil inlet is arranged on the valve bonnet.

Description

Angle Stop valves
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of Angle Stop valves.
Background technique
In order to the fluid in cutting out pipeline effectively, pipeline all can be provided with valve.Valve generally comprises: valve body, valve seat, flap and valve rod, existing valve is in use because the connecting passage in valve seat is less than the access way of valve body, when when easily scabbing and use in susceptible to plugging fluid workshop section, when valve closing, fluid often can block the connecting passage in valve seat, have a strong impact on normal production, existing valve is owing to infrequently using simultaneously, the control end of valve rod gets rusty easily and causes valve rod to rotate flap can not be made to open, there is potential safety hazard, in addition, at fluid through passage, a kind of function is only had to end or non-return, function ratio is more single, some places due to Long contact time wear rate high, cause valve shortening in working life, and usually because excesssive gap easily causes loosening between valve rod and valve gap, control inaccuracy, usage requirement can not be met well.
Summary of the invention
Technical problem to be solved by this invention is: the Angle Stop valves providing a kind of long service life.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: Angle Stop valves, comprise: valve body, valve body is provided with valve gap, the flap being provided with orthogonal passage and cooperatively interacting with passage in valve body, the valve seat cooperatively interacted with flap is provided with in described valve body, the connecting passage be interconnected with passage is provided with in described valve seat, the lower end of described flap is provided with contiguous block, the height sum of described contiguous block and flap is greater than the height of valve seat, flap is provided with evanohm block, one end of valve rod is provided with the circular arc cooperatively interacted with evanohm block protruding, evanohm block on flap and the circular arc projection on valve rod one end offset, the nut that the other end of valve rod stretches out on valve gap is connected with handle, described nut is connected by set screw with between valve gap, annular lubricant passage is provided with in described nut, described nut is provided with the filler opening be interconnected with annular lubricant passage, described valve gap is provided with the oil intake nozzle be interconnected with filler opening, the plug cock that to cooperatively interact with it is provided with in described oil intake nozzle, sealing gasket is provided with between two ends and valve rod up and down at described annular lubricant passage.
Advantage of the present invention is: above-mentioned Angle Stop valves, by the lower end at flap, contiguous block is set, when valve closing, flap is made to be full of connecting passage in valve seat, force and easily to scab and susceptible to plugging fluid cannot be attached to connecting passage in valve seat, remain that passage is smooth and easy, annular lubricant passage is set in the nut coordinated with valve rod simultaneously, regularly in annular lubricant passage, inject lubricant oil, keep rotating smoothly between valve rod and nut, can not get rusty, extend the working life of valve, this valve installation is on pipeline in addition, there is automatic pressure-relief function, buffer function well can be played in valve opening and closing process, valve rod is by contacting with the evanohm block on flap, greatly reduce the wear rate between them, nut on valve rod is connected with valve gap secondary by set screw, reduce rocking of valve rod, valve rod is made to control accurately, meet usage requirement well.
