Abstract
The utility model discloses a loose flange connects civilian dress formula voltage regulator, including the valve body and install executor and the cutting device at valve body middle part, the air inlet and the gas outlet of valve body all feed through has the ball valve, and the outer face of cylinder spiro union that fires tracheal tip and install loose flange and stop part, loose flange and ball valve is connected to the ball valve, stop part outside is equipped with external screw thread and circular bead, stop part and ball valve inner cylinder face spiro union, and the circular bead of stop part and the laminating of the terminal surface of ball valve are equipped with seal ring I between the circular bead of stop part and the ball valve. The utility model discloses the loose flange and the ball valve spiro union of voltage regulator can rotate and reciprocate, can adjust the relative position of flange at the scene when voltage regulator is installed to the pipeline stress that reduces or eliminate when installing is convenient for assemble.
Description
Technical field
The utility model is specifically related to a kind of loose flange and connects easy assembling type pressure governor.
Background technique
Gas pressure regulator, governor is commonly called as reduction valve, is also gas pressure regulating valve, is the gas flow by automatically changing through modulating valve, makes outlet gas keep the equipment of authorized pressure.Usually direct acting type and indirect acting type two kinds is divided into.Pressure governor is a kind of Special valve on fuel gas pipeline, no matter how the flow of gas and upstream pressure change, the device that downstream pressure is stable can be kept, upstream pressure can be reduced to a stable downstream pressure, downstream pressure can be limited when pressure governor breaks down in safety range.
In existing gas pressure regulator, governor, adpting flange and ball valve are an entirety, and flange position is fixing can not be adjusted, and because deviation appears in the flange position be connected with pressure governor in actual field is installed, just likely cause the situation of installing difficulty and even can not install.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of loose flange to connect easy assembling type pressure governor, installs the difficult problem even can not installed to solve existing pressure governor because flange position occurs that deviation causes.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of loose flange to connect easy assembling type pressure governor, the final controlling element comprising valve body and be arranged in the middle part of valve body and shut-off means, suction port and the air outlet of valve body are all communicated with ball valve, the end that ball valve connects fuel tube is provided with loose flange and stop member, and the external cylindrical surface of loose flange and ball valve is spirally connected; Be provided with outside thread and shoulder outside stop member, stop member and ball valve inner cylindrical surface are spirally connected, and the shoulder of stop member and the end face of ball valve are fitted, and are provided with seal washer I between the shoulder of stop member and ball valve.
As preferably, one end that stop member is positioned at ball valve inside is provided with step hole, is provided with the seal washer II being positioned at step hole between stop member and ball valve.
As preferably, stop member is cast iron quality.
the beneficial effects of the utility model are:
1, the suction port of valve body of the present utility model and air outlet are all communicated with ball valve, and the end that ball valve connects fuel tube is provided with loose flange and stop member, and the external cylindrical surface of loose flange and ball valve is spirally connected; Be provided with outside thread and shoulder outside stop member, stop member and ball valve inner cylindrical surface are spirally connected, and the shoulder of stop member and the end face of ball valve are fitted, and are provided with seal washer I between the shoulder of stop member and ball valve.Loose flange and ball valve are spirally connected and can rotate and move up and down, and can adjust the relative position of flange when pressure governor is installed at the scene, with reduce or eliminate install time pipe stress be convenient to assembling.
