Valve rod retreating prevention device for high-pressure valve
ActiveCN109931430AGuaranteed sealing effectEasy to operateOperating means/releasing devices for valvesEngineeringHigh pressure
The invention discloses a valve rod retreating prevention device for a high-pressure valve. The device comprises a valve body, a valve rod, a hand wheel, a mounting bar, a connection insertion block,a placing sleeve, a screw, a cylinder, a spring, a strip groove, a rubber head cover, a disc, a circular sleeve, a movable round rod, a first rubber sleeve, a connecting bar, a limiting groove, a through groove, a slot, a second rubber sleeve, an L-shaped groove, a sealing ring, an annular oil storage tank, a fine hole, a fixed pipe, a rubber bar, a connecting cylinder and a ball. The device is reasonable in structure; through an extension structure, the movable round rod can be lifted in the vertical direction; when the valve body is closed, the movable round rod can be inserted in the limiting groove of the hand wheel to prevent rotation of the hand wheel by external force; meanwhile, through arrangement of the bolt, the hand wheel can be limited; when the movable round rod is lifted, only the connecting bar slides in the strip groove and the L-shaped groove; and after the movable round rod is collected into the cylinder, the connecting bar moves to the tail end of the L-shaped groove, and the connecting bar can be stopped, so that the operation is simple.

Oil bottle without leakage
InactiveCN101485549ASolve the hourglassPrevent volatilizationClosuresBottlesSEMI-CIRCLEElastic plastic
The invention provides an oil bottle without dropping and leaking, which comprises a bottle body, a bottle cover and a straw, wherein the bottle cover is provided with an eagle nozzle; the eagle nozzle is provided with an oil channel inside; the upper end of the straw is inserted into the inlet of the oil channel; and the straw wall on the bottom of the straw is provided with four semi-circle gaps. The oil bottle has the advantages of effective dropping and leaking prevention, waste elimination, sanitary and convenient use and beautiful appearance and can effectively solve the problems that the oil bottle drops and leaks oil. The bottle body and the bottle cover can be made of nontoxic elastic plastics; the straw wall on the bottom of the straw is provided with the four semi-circle gaps, so oil can enter the straw from the gaps and the bottom; the upper end of the straw is inserted into the inlet of the oil channel of the bottle cover and interference is formed, so that the straw and the oil channel form a channel; and the bottle cover is screwed into the bottle body to become a whole. When oil is poured into the oil bottle, the bottle cover is screwed. When the oil bottle is used, a closed nozzle is opened, and the bottle body is griped to make the bottle wall deformed. The oil in the oil bottle enters the oil channel along the straw under the pressure action and ejects through an oil nozzle. The oil output amount can be manually controlled, and the oil output can be stopped by quickly reducing hand extrusion.
