Abstract
The utility model discloses a straight through adjustable throttle valve, which comprises a valve body (1), a valve seat outer sleeve (2), a valve seat (3), a valve core outer sleeve (4), a valve core (5), an adjustable valve rod (6), a valve cover (7) and a dustproof cover (8), wherein the valve seat outer sleeve (2) and the valve seat (3) are arranged in the valve body (1), and the valve core outer sleeve (4), the valve core (5) and the adjustable valve rod (6) are arranged in the valve body (1). The straight through adjustable throttle valve has simple structure and high throttle precision and can realize the secondary throttling of a pipe manifold.
Description
Technical field
The utility model relates to throttle valve, is specifically related to a kind of straight-through adjustable restrictive valve.
Background technique
Domestic oil recovery is difficult to show orifice size accurately with traditional throttle valve, and flow is excessive to cause the overload of pump and overheated, and working life is short, and energy consumption is also very big simultaneously; Flow is too small, and manufacturing efficiency is low, can not guarantee effectively that pump work efficient is in metastable state.
Summary of the invention
The purpose of this utility model is: a kind of straight-through adjustable restrictive valve is provided, utilize this throttle valve, throttling precision height can accurately show orifice size on display device, better control the pressure difference of upstream and downstream, be used for to realize on the choke manifold second throttle of manifold.
Technical solution of the present utility model is: be provided with three cribbing discharge orifices on the valve seat circumference, throttle orifice is up big and down small, by regulating moving up and down of throttling valve core, regulates the throttle diameter of throttle valve seat, reaches the purpose of throttling.Should comprise valve body, valve seat overcoat, valve seat, spool overcoat, spool, adjustable valve rod, valve gap, dust-proof cover by straight-through adjustable restrictive valve, valve seat overcoat and valve seat were installed in valve body, spool overcoat and spool and adjustable valve rod were installed in valve body.
In the straight-through adjustable restrictive valve of the present utility model, on the valve seat circumference, be provided with the up big and down small throttle orifice of three rows.
In the straight-through adjustable restrictive valve of the present utility model, adjustable valve rod is connected with spool.
In the straight-through adjustable restrictive valve of the present utility model, adjustable valve rod upper end is provided with dust-proof cover.
In the straight-through adjustable restrictive valve of the present utility model, valve gap is connected with valve body.
The utility model is simple in structure, and throttling precision height can be realized the second throttle of manifold.
