Abstract
The utility model relates to a fluid control valve which is composed of a valve body, a valve base, a valve core and a valve handle. The fluid control valve is characterized in that the valve handle is arranged at the circular cutting surface of the cylindrical valve body, and through a section of worm screw arranged on the valve handle, the valve handle is meshed with the valve core of a section of a worm gear tooth arranged at the inner lateral edge of the valve body. The valve core and the valve base are both concentric with the valve body and are both provided with a circular plate with a circulation channel. The valve base is sealed to connect with the valve body, while the valve core is overlapped to cover on the central shaft of the valve base. The valve handle is arranged in a worm screw box which is formed by a sealing assembly element tangentially arranged at the periphery of the valve body, and is connected with a drive device through a drive rod extended from one end of the worm screw box.
Description
The utility model relates to a kind of control valve for fluids, belongs to valve type, in various fluid feed line.
Sell the valve that uses in the market and can reduce three classes: stop valve, ball valve and gate valve.Wherein the sealing surface of stop valve is the plane, and the form that goes out on advancing below the fluid is by valve, and its spool is done the upper and lower displacement perpendicular to sealing surface; Thereby cause fluid motion to be non-linear, make energy loss bigger.Simultaneously, because the sealing surface single face of spool bears system's internal pressure, valve core sealed cover malleation on valve seat, in case when medium contains granule foreign, cause leakage easily; And easy oscillatory stability is poor, and body cavity is big, cavitates, the fluid erosion phenomenon is serious.The spool of ball valve is the spheroid perpendicular to valve axis, and its sealing surface is a sphere.Not only difficulty of processing is big, and because spool rotates under the drive of valve rod, and the moment of required rotation is big, relatively more difficult for bigbore such valve operation.Described gate valve, its spool are the flat board perpendicular to the valve body circulation passage, and the motion of spool is to move up and down in the sealing plane; Especially bigbore gate valve is not only operated effort, and because the volume of valve body is big, processed complex; Must be through casting.
Can see in sum: the three class valves that appear on the market at present, though each has something to recommend him on the structure, its fairly obvious deficiency is also respectively arranged.Therefore, very need a kind of not only good sealing effect in actual production, the life, do not have outer discharge, and concrete again long-pending little, in light weight, simple in structure, rapid operation, can be adapted to the new valve type that different fluid is separated matter simultaneously again.
The purpose of the present utility model: promptly providing a kind of valve of new structure, wishing that it can collect the advantage of above-mentioned three class valves, can overcome their defective again; Accomplish existing than high sealing performance, concrete long-pending again little, in light weight, laborsaving easy-operating characteristics.
