Abstract
A novel American-standard stop valve for a pipeline-controlled medium flowing device comprises a valve body, a valve cap, a valve rod, a valve clack, a handwheel, an indicator, a pointer, an indicator scale and other components. An indicating device is mounted on the outer wall of the valve body, thereby solving the problem that the position of the valve clack in a cavity cannot be judged. The valve clack is in the shape of trapezoid and positioned in the middle of the valve body; a groove is formed at the upper end of the valve clack; and the valve rod is inserted into the groove and fixed through a divided ring, and then the divided ring is compressed through a valve clack cap. The valve cap and the valve body are sealed through a central cushion; filling material is placed in a stuffing box; and the stuffing box is positioned at the neck of the valve cap and compressed by a stuffing box gland. The indicating device consists of the indicator, the pointer and the indicator scale; the indicator is arranged at the lower end of the handwheel and fixed by a retaining ring; scale marks are formed on the indicator; a ring groove is formed in the middle of the indicator; the indicator moves along with the valve rod together, and vertically moves along the pointer through the ring groove; and the pointer is fixed at the upper end of the valve cap and is static relative to the valve body.
Description
Technical field:
The utility model relates to a kind of pipeline control media flow device, especially relates to it and has indicating device, has solved flap and can't judge its position in cavity, the blindness of having avoided valve to open and close.
Background technique:
Stop valve is marked by U.S. of medium cut-out or circulation in delivery lines such as food, medicine, oil, chemical industry, rock gas, iron and steel, environmental protection, papermaking at present, flap moves along the valve seat center line, the variation of valve seat port is and flap stroke relation in direct ratio, because of judging whether valve is opened or closed and put in place, new equipment attendant particularly to lacking experience, can't see the certain situation of valve internal, cause its adjusting that blindness is arranged, cause valve short working life, the wasting of resources also strengthens user cost.
The model utility content:
The utility model is for overcoming the deficiencies in the prior art, and a kind of novel U.S. mark stop valve of pipeline control media flow device is provided, and is made up of valve body, valve gap, valve rod, flap, handwheel, indicator, pointer, indicator scale etc.
The technological scheme that its technical problem that solves the utility model adopts is: at valve outer wall indicating device is housed, has solved flap and can't judge its position in cavity.Flap is made trapezoid shaped and is put at valve body middle part, and the upper end is provided with groove, and valve rod inserts groove, with the fixing valve rod of divided ring, covers with flap and compresses divided ring.Between valve gap and the valve body, do sealing with the middle part pad.Filler is in the stuffing box the inside, and stuffing box compresses with Gland at the valve gap neck.Indicating device is made up of indicator, pointer, indicator scale, and indicator is located at the handwheel lower end, fixes with back-up ring, and the scale sign is arranged on the indicator, and the indicator middle part is provided with annular groove.Indicator is followed valve rod and is moved together, moves up and down along pointer by annular groove, and pointer is fixed on the valve gap upper end, and valve body is static relatively.
The beneficial effects of the utility model are: working stability, the valve internal state is grasped fast, and make things convenient for client's valve operation, increase the service life.
