Abstract
The utility model relates to the improvement of a valve. A piston cylinder is arranged in the valve body of a slide type slowly closing check valve, and the cylinder and the valve body are integrally manufactured. One end of the piston cylinder is connected by a press cover and a sealing ring through bolts. A tongue plate is position on one end of a piston rod in a cylinder. When a lift pump stops working, the return water impacts the tongue plate to be slowly closed under the action of the piston. The utility model has the advantages that the performance is safe, the water hammer is eliminated, the big borne press is big, the temperature influence of the aqueous medium is not have, etc.
Description
The utility model relates to a kind of improvement of valve.
The water valve that use from the underground water lines of extracting former water earthward in present water supply industry, chemical industry, mine etc., traditional gate valve is arranged, this valve exists the shut-in time and occurs water hammer soon easily, cause the damage of valve body, flashboard, water outlet time gating plate resistance power is big, expend the energy, the appearance of Tiny Drag Slow Shut Check Valves in recent years, solved and produced water hammer in the valve body, and when the water pump water lift, demonstrate superiority aspect the saving power, but this valve is adapted to small-bore valve, and pressure resistance is little, and application area is limited to.
The utility model purpose provides a kind of gliding style buffer valve that is provided with the piston system of hyoplastron and limit hammer in valve body, to solve the deficiency of safety check in the past.
The utility model is by valve body, hyoplastron, piston is formed, valve body 1 is connected by seal ring 3 usefulness bolts with valve body 2, one end of piston/cylinder 4 is connected with the supporting rib of valve body 2, the other end ectosome of piston/cylinder 4 is fixed on the valve body supporting rib 5, end face is linked together by screw by gland 6 and seal ring 7, piston rod 8 is positioned at the piston/cylinder middle part, hyoplastron 9 is connected with piston rod by bolt, gland and piston/cylinder inboard are respectively equipped with seal ring 10 and 11, piston 12 in piston/cylinder is provided with seal ring 13 with the piston/cylinder joint, the section part of piston is provided with oil-through hole 14, the water inlet oral-lateral of hyoplastron is equipped with sealing gasket 15, compressing tablet is fixed on the hyoplastron by screw 16 of compressing tablets thereon, and the water outlet oral-lateral of hyoplastron is processed into matrix.Valve body and hyoplastron can be processed into the cylinder bodily form or multiedge cylinder shape, and oil-through hole 14 can be provided with two and be positioned at piston/cylinder one side, outsidely are connected by director valve.
It is safe and reliable to the utlity model has usability, and pressure can reach 320 kilograms/cm
2, the aqueous medium temperature can reach 400 ℃, characteristics such as no water hammer.
Accompanying drawing 1 is a main pseudosection of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described, the utility model is to be processed by cast steel, the supporting rib of valve body inner carrier cylinder body one end on valve body is cast in, the other end ectosome of piston/cylinder is fixed on the valve body supporting rib, the piston/cylinder inlet end is connected as a single entity by screw by gland and seal ring, piston rod inserts the gland mesopore, the middle part is provided with piston and seal ring in the piston/cylinder, piston rod one end is equipped with the hyoplastron of valve, the other end is positioned at the piston rod hole on the piston/cylinder, be provided with seal ring in the contacting point of piston rod and piston/cylinder and the contacting point of piston rod and gland, to prevent that the hydraulic oil in the piston/cylinder from leaking, contacting point at piston and piston/cylinder is provided with seal ring, prevent that the hydraulic oil in the cylinder from going to opposite side from a side of piston, the water inlet oral-lateral of hyoplastron is equipped with sealing gasket, when contacting with the water intake flange, plays hyoplastron sealing water and buffer function, the water outlet oral-lateral of hyoplastron is processed into matrix, when effluent recycling to strengthen impact force to hyoplastron, hyoplastron is reliably closed, be processed with oil-through hole on the piston body in the piston cylinder, when piston slides in cylinder body, oil in the cylinder body can pass through this orifice flow mistake, oil-through hole also can be processed the side at piston/cylinder, be processed into diplopore, be connected by director valve and output oil pipe, director valve can the interior hydraulic pressure oil mass of regulating piston cylinder.The utility model working principle is to realize like this, when pump working, the water of being extracted out by water pump enters in the valve body by the valve inleting water mouth, hyoplastron leaves the water-in flange mouth under current promote, move to the water outlet direction, piston in the piston/cylinder moves to same direction under the effect of piston rod, the hydraulic oil that is positioned at piston/cylinder one side flows to opposite side by oil-through hole, finish the valve opening action, when water pump quits work, there is the water natural back flow in the pipeline, when current flow to the hyoplastron position,, produce very big pressure because hyoplastron is processed into matrix by water inlet and outlet one side, hyoplastron drives piston rod and piston slowly moves, move to valve inleting water mouth flanged surface place and close, can not produce water hammer like this, the working pressure of valve improves greatly, in use be not subjected to the influence of medium temperature, bore can be processed into φ 50mm to φ 2000mm.
