Abstract
The utility model discloses a ball valve which comprises a valve body (1). A check block (2) is arranged on the upper portion of the valve body, a valve rod (3) is axially arranged on the valve body, a limit washer (4) is sleeved on the valve rod protruding from the valve body and rotates along with the valve rod, the limit washer is provided with a flange (41) acting with the check block to enable the valve to be completely opened or completely closed, two acting faces (411) are arranged on the flange, an included angle between the two acting faces is 90 degrees, the check block is provided with two limit faces (21) acting with the acting faces, the included angle between the two limit faces is 180 degrees, and the two limit faces are overlapped with a plane where the axial lead of the valve rod lies. According to the ball valve, the size of the position where the check block on the valve body of the ball valve lies can be effectively measured, the badness ratio that the ball valve is completely opened or completely closed is reduced, opening and closing of the ball valve can be precisely controlled, and machining is simple.
Description
Technical field
The utility model relates to the ball valve for refrigeration system.
Background technique
At present, the construction of switch of common ball valve comprises the ball valve main body on the market, is arranged on connecting rod on the ball valve main body and the block of 90 ° of protrusions, and connecting rod is provided with pin and spacing shim, by the fixing spacing shim of pin, the block of spacing shim and protrusion is realized ball valve completely open and close limit rotation jointly.This structure is because of the restriction of the block of 90 ° of protrusions, course of working is difficult to measure the size of control valve ball standard-sized sheet full cut-off, affect machining accuracy, cause ball valve to cross out or reach a standard, can't accurately control the operation of the Push And Release of ball valve, and this structure is higher for the pin-and-hole size requirement on pin and the valve ball connecting rod, and difficulty of processing is larger, cooperates not in placely then to cause pin to be pressed not enter or sell and drop.
Summary of the invention
Problem to be solved in the utility model provides ball valve, and processing is simple, can accurately control the Push And Release of ball valve.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: ball valve, comprise valve body, the top of valve body is provided with block, valve body be axially arranged with valve rod, expose valve body on the valve rod and partly overlap the limited location pad, described spacing shim is followed valve rod and is rotated, it is characterized in that: described spacing shim is provided with the flange that makes valve standard-sized sheet or full cut-off with the block effect, described flange is provided with two acting surfaces, and the angle between two acting surfaces is 90 °, and described block is provided with two confined planes with the acting surface effect, angle between two confined planes is 180 °, two confined planes and valve rod shaft axis place planes overlapping.
Improved, described block is a hemizonid that circumferentially arranges along spacing shim, and described confined planes is two end faces of hemizonid.
Improved, described block is that the angle between two confined planes of two projections and flange two acting surface effects is 180 ° along circumferential equally distributed two projections of spacing shim.
Improved, described valve rod exceeds the valve body part and is circumferentially with annular groove along valve rod, the flexible back-up ring of described annular groove inner sleeve.Spacing shim is played the effect of axially locating.
Improved, described circlip is fixed between the upper wall of annular groove upper wall and spacing shim.Spacing shim is played the axially locating effect.
Improved, be provided with fitting surface between described spacing shim and the described valve rod, described fitting surface is plane or non-round surface.Valve rod can drive spacing shim and rotate when rotating.
Beneficial effect:
After adopting technique scheme, this model utility ball valve is set as 90 ° with the angle between two acting surfaces on the flange, and two confined planes on the block are made as 180 °, and two confined planes place planes overlapping and with valve rod shaft axis place planes overlapping, reduced the bad ratio of ball valve completely open and close, can accurately control the Push And Release of ball valve, process also simple.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
