Abstract
The utility model relates to a valve which is a fluid control valve, the fluid control valve is applied to engineering, such as petroleum, coal gas, chemical industry, water conservancy, heating, pollution discharge, etc. The fluid control valve comprises a valve and a hydraulic control station. The improvement of the fluid control valve is that the handwheel assembly of a traditional hand valve is change into a hydraulic oil cylinder, the valve body is connected with the cylinder body of the oil cylinder, the valve flap of the valve body is connected with the piston rod which extends outward from the cylinder body, and the opening of the liquid control is achieved by the liquid control station and the oil pipeline. The fluid control valve ahs the advantages of labor saving, remote control, no environmental limit, high efficiency, and good safety. The fluid control valve can achieve centralized control, program control or automatic control.
Description
Technical field
The utility model relates to a kind of valve, and promptly fluid-control valve is applicable in the engineerings such as oil, coal gas, chemical industry, water conservancy, heating, blowdown and uses.
Background technique
In prior art, valve commonly used comprises valve body, flap (as flashboard or valve ball) in the valve body, flap connects opens valve rod and handwheel, turns handwheel drive flap and moves, and realizes opening, its shortcoming is to open effort, when especially valve is in diverse location, open inconvenience especially, need pedal high building as the valve that switch is on the high building; Switch is in the valve in the tunnel, need creep into tunnel; For the hidden valve in the potential water, the operator need slip in the water, particularly discharges the operation of toxic gas or toxic liquid and needs to cut upward respirator, and the abominable local mounted valve of environment is operated very inconvenient.
The model utility content
The purpose of this utility model is to provide a kind of unlatching laborsaving at above-mentioned deficiency, the fluid-control valve of telecontrol.
Technical solution of the present utility model is: fluid-control valve comprises valve, hydraulic control station.Each valve comprises the flap in valve body, the valve body.Improvements are to change the handwheel assembly of traditional manually-operated gate into hydraulic jack, are about to valve body and are connected with the cylinder body of oil cylinder, and the piston rod that stretches out in the interior flap of valve body and the cylinder body is connected.By hydraulically controlled station and the oil pipe line of arranging, realize the hydraulic control unlatching, the purpose of telecontrol.
The utility model has the advantages that: 1, open and realize hydraulic control, laborsaving.2, telecontrol can be controlled height on high building, in the tunnel, or the hidden valve in the potential water and the valve of hazardous environment, be not subjected to environmental constraint, safe in utilization.3, remove handle wheel without hand, pressing button just can switch valve, can centralized control, program control or control quickness and high efficiency automatically.
Below in conjunction with accompanying drawing the utility model is described in further detail.
