Abstract
The utility model provides an automatic pressure regulating valve. The traditional valve only has a function of on-off, but no function of pressure regulation; even if a function exists, that is, automation. The utility model relates to an automatic pressure regulating valve which automatically regulates the pressure of the outlet according to the pressure of the inlet, consisting of a handwheel, a screw rod, a valve body and a valve core. The valve core is positioned in the valve body; the valve body is provided with the inlet and the outlet. The valve core is positioned between the inlet and outlet which are connected by a communication tube inside the valve body. The utility model is characterized in that the inlet of the valve body is provided with a pressure regulating tube, one end of the regulating tube is communicated with the inlet, and the other end is communicated with the lower part of the valve core, at which a plurality of through holes are arranged on the valve core in a big end up way, and the valve core is connected with the screw rod by a spring.
Description
Technical field
The utility model relates in particular to a kind of automatic pressure regulator that can adjust mouth pressure according to the pressure of import automatically relevant for a kind of valving.
Background technique
Valve is parts commonly used in the various pipelines (comprising liquid road and gas circuit), is used for the logical and disconnected of pilot line flowing liquid or gas.Common valve does not generally have the pressure regulation effect.Some valve major parts with pressure regulation effect all are manual.
The model utility content
Therefore, the purpose of this utility model is to provide a kind of automatic pressure regulator that can adjust gas port pressure according to the pressure of suction port automatically.
According to above-mentioned purpose of the present utility model, automatic pressure regulator of the present utility model comprises: handwheel, screw rod, valve body and spool, described spool is positioned at described valve body, described valve body has import and outlet, described import with the outlet between be connected by a connecting pipe road, described spool is between described import and described outlet, it is characterized in that, on described valve body, in described inlet, also be provided with a pressure regulation pipeline, the one end is connected with described import, and its other end is communicated to described spool bottom, and described spool is provided with many through holes, arrange by up big and down small mode, be connected by a spring between described spool and the described screw rod.
Compared with prior art, automatic pressure regulator of the present utility model has changed the working method of traditional manual voltage regulation, by having set up the pressure regulation pipeline, has realized the purpose of automatic Regulation.
Description of drawings
Fig. 1 is the structural representation of automatic pressure regulator of the present utility model.
Embodiment
See also shown in Figure 1ly, Fig. 1 shows a kind of concrete structure of automatic pressure regulator of the present utility model.It includes valve body 1 and spool 2.Valve body 1 is a hollow shape, and spool 2 is installed in this hollow article.On valve body 1, be provided with import 11 and outlet 12, import 11 with export 12 between be connected by a connecting pipe road 13.Core body 2 is in import 11 and export between 12, and core body 2 is provided with many through holes 21, and these through holes are arranged by up big and down small mode.Gas or liquid enter valve body 1 from import 11, discharge from exporting 12 by the through hole 21 on connecting pipeline 13, the spool 2.On valve body 1 top, spool 2 links to each other with a screw rod 4 by a spring 3, and handwheel 5 is connected screw rod 4 upper ends.When rotating handwheel 5, position that can up-down adjustment spool 2, thus the through holes 21 of different sizes are alignd with connecting pipeline 13, the realization manual voltage regulation.
On the top of valve body 1, be respectively arranged with valve gap 6 and seal ring 7, the effect of these two parts is to guarantee that the hollow cavity of valve body 1 envelope is close.
See also Fig. 1 again, on valve body 1, except connecting pipeline 13, also set up a pressure regulation pipeline 14, an end of this pressure regulation pipeline 14 is connected with import 11, and the other end is communicated to the bottom of spool 2.This pressure regulation pipeline 14 is the key points that realize valve automatic Regulation of the present utility model.
When automatic pressure regulator of the present utility model was worked, liquid or gas entered into valve body 1 through import 11, and it has the two-way path, and one is passed through the through hole 21 on connecting pipeline 13, the spool 2 and exports 12 discharges; Another is communicated to the bottom of spool 2 through pressure regulation pipeline 14.When the gas of import 11 ends or fluid pressure are higher, these pressurized gas or liquid enter into spool 2 bottoms through pressure regulation pipeline 14, improve thrust upwards to spool 2, spring 3 stressed being compressed, move on the spool 2, spool 2 through hole 21 less than the bore of bottom alignd with connecting pipeline 13, thereby reduce to export the delivery pressure at 12 places.If the gas or the fluid pressure at import 11 places reduce, then the thrust of spool 2 bottoms is also corresponding reduces, and under the effect of the restoring force of spring 3, spool 2 is moved down, the through hole 21 that spool 2 is bigger than the bore on top aligns with connecting pipeline 13, thereby increases the delivery pressure at outlet 12 places.So can realize the function of automatic Regulation.
