Abstract
The invention discloses a liquid valve with pipe orifice diameters larger than 50 millimeters. The liquid valve with the pipe orifice diameters larger than 50 millimeters is mounted between system pipelines and a control pipeline via pipelines. The liquid valve with the pipe orifice diameters larger than 50 millimeters has the advantages that a difference value of two pressures can be sensed by the liquid valve, so that working pressures of systems can be automatically regulated; the liquid valve is of a mechanical structure, accordingly, the systems can work reliably, and the liquid valve is small and light, is low in machining cost, convenient to mount, simple in maintenance, adaptive to various environments and long in service life and can be widely applied to pipelines with pressure regulation and control requirements.
Description
Technical field
The present invention relates to mechanical field, specifically provide the liquid valve that a kind of nozzle diameter is greater than 50 millimeters.
Background technique
Pressure in liquids in general or gas piping system regulates, control, and commonly uses pressure regulating valve.
But this valve can only be experienced single pressure and regulate, if when needing the difference of two pressure to regulate, conventional pressure regulating valve just cannot be competent at.
When needing the difference of two pressure to carry out the pressure of control system, conventional pressure regulating valve being changed into the liquid valve that nozzle diameter is greater than 50 millimeters, the pressure P in system can be made to realize automatically regulating with the difference of P1, P2.
Summary of the invention
The object of this invention is to provide a kind of pressure differential valve that can realize being come by the difference of two pressure control system pressure.
The liquid valve that nozzle diameter is greater than 50 millimeters, is characterized in that: the liquid valve (1) that described a kind of nozzle diameter is greater than 50 millimeters is arranged between system pipeline (2) and pilot line (3) by pipeline.
The liquid valve (1) that described a kind of nozzle diameter is greater than 50 millimeters comprises valve body, valve base, valve, valve housing, low voltage control joint, high voltage control joint, import, outlet, upper cover;
Its valve body is arranged on valve housing by screw thread, the inwall close contact of one end of the large end of valve base and valve body is installed, small end overlaps the valve that can move axially, low voltage control jiont treatment is on the top of valve housing side, high voltage control jiont treatment is in the bottom of valve housing side, import is arranged on the bottom of valve housing by screw thread, exports the side being arranged on valve housing by screw thread, and upper cover is arranged on the other end of valve body by screw thread.
The adjustment that the liquid valve (1) that described a kind of nozzle diameter is greater than 50 millimeters also comprises for regulating valve gate seat position is followed closely and makes the elastic element of valve reset; Its adjustment nail is arranged on the top of upper cover by screw thread, elastic element is arranged between valve base and valve.
Described elastic element is silk spring or is leaf spring.
Between described upper cover and valve body, seal ring is housed, 2 to 6 seal rings are housed between valve body and valve housing, between low voltage control joint and valve housing, seal ring is housed, between high voltage control joint and valve housing, seal ring is housed.
Advantage of the present invention:
The liquid valve that described a kind of nozzle diameter is greater than 50 millimeters can experience the difference of two pressure, realize the automatic adjustment of system working pressure, owing to being mechanical structure, system works is reliable, volume is little, lightweight, processing cost is low, easy for installation, safeguards simple, can various environment be adapted to, long service life.
Accompanying drawing explanation
below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
Fig. 1 is that the liquid valve system that nozzle diameter is greater than 50 millimeters installs sketch.
