Description
Technical field
The utility model relates to a kind of gas pressure regulating apparatus, is a kind of novel gas pressure governor specifically.
Background technique
Gas pressure regulator, governor is a kind of device for carrying out pressure regulation to other non-corrosiveness gases such as rock gas, liquefied petroleum gas (LPG), artificial coal gas, mine drainage gas, and it is large that gas pressure regulator, governor is applicable to inlet pressure fluctuation, mesolow, the door station of large discharge or region pressure regulation.
, easily there is surging phenomenon in the spool fluctuation of service of existing gas pressure regulator, governor, simultaneously the stability of pressure governor and precision poor, response speed is slower.
Model utility content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of novel gas pressure governor, and its good stability, avoids surging phenomenon, and precision is high, and response speed is fast.
In order to solve the problem, the utility model is by the following technical solutions: a kind of novel gas pressure governor, it is characterized in that, comprise body, suction port, air outlet, piston sleeve, spool, valve seat, valve rod, built-in signal pipe, surge-chamber, described suction port is connected by the valve seat be arranged on valve port with air outlet, described spool is located at the upper end of valve rod, spool is positioned at above valve seat, spool top is provided with piston body, spool bottom is provided with the pressure mouth matched with valve seat, pressure mouth inwall is also provided with sealing gasket, the top of valve port is provided with the piston sleeve matched with piston body, the top of piston body is positioned at piston sleeve inside, the surface of contact of piston sleeve and piston body is provided with seal ring, Compress Spring is provided with between piston body and piston sleeve, described surge-chamber is located at the below of body, surge-chamber is divided into upper chamber and lower chambers by the diaphragm be arranged in surge-chamber, lower chambers is communicated with outside atmosphere by spiracle, be connected by eye bolt between upper chamber with air outlet, the built-in signal pipe being communicated with upper chamber and air outlet is also provided with between upper chamber with air outlet.
The beneficial effects of the utility model are:
1, the built-in signal pipe being communicated with upper chamber and air outlet is also provided with between upper chamber with air outlet, increase Throughput between upper chamber and air outlet, pressure signal collection is more accurate simultaneously, feeds back rapider, effectively upset surge frequency, avoid surging phenomenon.
2, spool top is provided with piston body, and spool bottom is provided with the pressure mouth matched with valve seat, and pressure mouth inwall is also provided with sealing gasket, and the setting of pressure mouth improves the seal between spool and valve seat, facilitates cooperatively interacting between valve seat and spool simultaneously; The top of valve port is provided with the piston sleeve matched with piston body, and the surface of contact of piston sleeve and piston body is provided with seal ring, adds stability and the anti-pressure ability of valve core movement, makes spool more accurate with coordinating of valve seat.
