Abstract
The utility model discloses a fuel-gas pressure regulator with an emergency shutoff device mainly comprising a valve cover, a valve seat, a pressure regulator and an emergency shutoff device. The utility model aims to overcome the difficulties in the prior art and design a linkage structure, which can combine an unattached pressure regulator with the emergency shutoff device to become an integral structure, and at the same time, and make the regulator had the functions of pressure regulating, leakage alarming and gas source cutting off.
Description
Technical field
The utility model relates to the gas pressure regulator, governor field, a kind of gas pressure regulator, governor with emergency shutoff device of saying so more specifically.
Technical background
At present, the pressure regulation majority of pipeline gas is to adopt a building concentrated pressure regulation, there is pressure surge in combustion gas user's gas appliance inlet, make the combustion instability and the burning of gas appliance insufficient, make the inlet pressure of gas appliance stable, service regulator must be installed, and owing to safe requirement, the combustion gas user need install indoor emergency shutoff device simultaneously again.General combustion gas user is equipped with gas meter indoors, if pressure governor and emergency shutoff device are installed simultaneously again, so just need very big space, for the kitchen or the bathroom that use gas appliance, because its narrow space is so the rational Application in space seems even more important; And,, user's lives and properties are caused certain threat so the repeatedly connection that just keeps away unavoidable gas pipeline when installing has so just increased the hidden danger of gas leakage because pressure governor of the prior art and emergency shutoff device all are members independently.
Summary of the invention
The purpose of this utility model is to overcome difficult point of the prior art, designs a kind of structure of interlock, will be independently pressure governor and the emergency shutoff device formula structure that is combined into one, make it possess the function of pressure regulation, leakage alarm and cut-out source of the gas simultaneously.
The utility model is mainly realized its goal of the invention by following technology:
The utility model is a kind of gas pressure regulator, governor with emergency shutoff device, mainly constitute by valve gap, valve seat, pressure regulator and emergency shutoff device, pressure regulator is installed between valve gap and the valve seat, emergency shutoff device is located at the valve gap outside, it is characterized in that pressure regulator is made of adjusting bolt, sliding sleeve, Returnning spring, spring bearer plate, Regulation spring, diaphragm, valve core; Sliding sleeve and valve gap are slidingly matched, and are provided with Returnning spring between sliding sleeve and the valve gap, and emergency shutoff device is provided with spring bolt, and spring bolt passes valve gap and is stuck on the sliding sleeve; The adjusting bolt of pressure regulator is located in the sliding sleeve, and end is provided with gland and sliding sleeve is slidingly matched; Valve core is slidingly matched by spring bearer plate and sliding sleeve, between valve core and the spring bearer plate for being slidingly matched; Spring bearer plate is located at gland below, and is provided with Regulation spring between the diaphragm of spring bearer plate and pressure regulator, between described sliding sleeve and the spring bearer plate, respectively be provided with screens between spring bearer plate and the valve core.Since between valve gap and the sliding sleeve, between sliding sleeve and the spring bearer plate, between spring bearer plate and the valve core all for being slidingly matched, each member can be with respect to the member slide relative in certain scope that is placed in inside and outside it, so in the process of using, with spring bolt the relative position between sliding sleeve and the valve gap is fixed earlier, and make Returnning spring be in pressured state, promote gland, spring bearer plate and Regulation spring successively with regulating bolt, Regulation spring compacting valve core, open the suction port of gas-entered passageway, Regulation spring is also suppressed the air pressure that diaphragm is regulated gas-entered passageway simultaneously.When if gas leakage reaches certain degree, emergency shutoff device just can send chimes of doom, and unclamp spring bolt simultaneously, slide under the effect of Returnning spring and move upward, because between sliding sleeve and the spring bearer plate, respectively be provided with screens between spring bearer plate and the valve core, so sliding sleeve spurs spring bearer plate successively and valve core makes progress, and valve core is sealed suction port.At this moment, even the alarm release of emergency shutoff device or remove power supply, valve core is all with inlet close, can not recover air feed automatically, need manually depress sliding sleeve, could recover air feed, because the pressure of Regulation spring is constant, so the utility model can continue to keep original pressure of setting constant, need not manually to regulate once more.
The top of valve core of the present utility model is provided with a boss, and spring bearer plate has eccentric 8 font holes, and the big bore dia in eccentric 8 font holes is greater than the diameter of boss, and the hole diameter in eccentric 8 font holes is less than the diameter of boss.This structure can guarantee that valve core can fit inside from macropore, and can not be pulled out by aperture, can simply realize the serial verb construction between spring bearer plate and the valve core, and simple and convenient when installing.
The utility model can guarantee that with the structure that central cross-section is a ∏ shape that is made into of gland valve core can be done certain slide relative with respect to spring bearer plate when adopting the adjusting bolt to regulate air pressure, and the size of sliding distance depends on the height with the gland inner chamber.Simple in structure, easy for installation, member that need not be too many just can be realized the adjusting in the certain limit.
For guaranteeing to use the relative position of original state sliding sleeve and valve gap, the sliding sleeve outside is provided with draw-in groove and engages with spring bolt.Use the mode of screens can simply realize the fixing of sliding sleeve position, and emergency shutoff device only need the simple advance and retreat that realize spring bolt just can, simplify whole structure greatly.
The utility model can also integrate with gas meter, further saves its occupation space.
The utlity model has the advantage of following conspicuousness with respect to prior art:
1. pressure governor and the emergency shutoff device formula structure that is combined into one possesses the function of pressure regulation, leakage alarm and cut-out source of the gas simultaneously;
2. integral structure is saved the space, is fit to general kitchen guarding and installs;
3. integral structure reduces the member and the program of installing, and has improved the Security that combustion gas is used;
4. main member adopts the serial verb construction that is slidingly matched, and is simple in structure, installs simple and easy;
5. must manually recover after having an accident, guarantee the Security of using;
6. need not pressure regulation once more after manually recovering, use simple and convenient.
