The electromagnetic emergency shut-in valve is characterized in that the locking pin is composed of a manual locking pin body and an electric locking pin body, the manual locking pin body is composed of a hinge pin and a lock body, the hinge pin is installed in a pin hole of the valve deck, the hinge pin is movably installed in an inner hole of the lock body, a spring is installed between the end face of the inner hole of the lock body and a protruding shoulder of the hinge pin, a clamping protruding shoulder is arranged between the inner hole of the lock body and the hinge pin, the electric locking pin body is composed of a lock pin, a framework, an electromagnetic coil and a spring, the framework is fixedly installed on the valve deck, one end of the lock pin is arranged in a pin hole of the valve deck in a sleeved mode, the other end of the lock pin is arranged in a center hole of the framework in a sleeved mode, and a spring is installed between the end face of the portion, located in the center hole of the framework, of the lock pin and the inner end face of the center hole of the framework. The electromagnetic emergency shut-in valve has the advantages of being reliable in lock, obvious in opening state and closing state and the like.
Description
Technical field
The utility model relates to valve field, particularly about a kind of emergency shut-in valve.The utility model is applicable to the emergency cut-off valve of gas pipeline.
Background technique
Emergency shutdown when emergency shut-in valve is installed on pipeline as burst accident, while normally working in normally open.The structure of existing emergency shutdown valve generally comprises valve body, flap, valve rod, valve gap, closes spring and open valve lockout devices.In normal operation, flap is driven and opens by valve rod, and valve rod is opened valve lockout devices locked position; When there is emergency case, open valve lockout devices and unclamp valve rod, to close spring and make flap quick closedown, Accident prevention spreads.Its major defect is complex structure, can not judge open and close state.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, provide a kind of simple in structure, there is manually and electric lock and electromagnetic type emergency shut-in valve that can intuitive judgment valve open/close state.
The technical solution of the utility model comprises valve body, flap, valve rod, valve gap, locking device, and flap fixed installation valve rod lower end, installs return spring between the flap back side and valve gap, and locking device is comprised of the locking slot on valve rod top and the stop pin on valve gap, mainly that stop pin is comprised of manual lock rationed marketing and electric lock rationed marketing, manual lock rationed marketing is comprised of the bearing pin and the lock body that are arranged in valve gap pin-and-hole, bearing pin is movably arranged in lock body endoporus, mounting spring between hole end surface and bearing pin convex shoulder in lock body, between lock body endoporus and bearing pin, be shaped with screens convex shoulder, electric lock rationed marketing is by lock pin, skeleton, electromagnetic coil and spring form, skeleton is fixedly mounted on valve gap, lock pin one end is sleeved in the pin-and-hole of valve gap, the other end is sleeved in frame center hole, mounting spring between lock pin end face in frame center hole and the interior edge face in frame center hole.
In above technological scheme, valve gap upper-end surface and valve rod upper end portion are provided with switch indicating device, and this switch indicating device is comprised of with the pointer that is fixedly mounted on valve rod upper end portion the direction board that is arranged on valve gap upper-end surface.
The utility model has the advantages that manual lock rationed marketing and electric lock rationed marketing form, when electric lock rationed marketing fault, can adopt manual lock rationed marketing that flap is locked in to opening state, and between valve gap upper-end surface and valve rod upper end portion, switch indicating device is set, there is the features such as locking is reliable, on off state is obvious.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
