Description
Technical Field
The utility model relates to a gas pressure protection technical field specifically is a modified gas pressure warning blocking device.
Background
Gas pressure protection device: the gas pressure of the inflating equipment can be indicated by the indicator, and when abnormal pressure is generated or the gas pressure reaches a set value, the contact mechanical device can control different electrical components such as an alarm and a control relay in a loop connection or disconnection mode, so that the main equipment is protected.
According to the regulation of power equipment handover and preventive test regulations, the gas pressure protection device is checked every 1-3 years, so that the pressure display of the gas pressure protection device is correct; when slight air leakage occurs, the alarm value is reached and a signal is correctly sent out; when the serious air leakage reaches the locking value, a control loop of the main equipment is cut off, all operations are forbidden, and the accidents of explosion and equipment burnout are prevented. Therefore, the verification of the gas pressure protection device is very important and is the most important measure for protecting the equipment adopting the gas insulation.
Among the prior art, gas pressure protection device generally all is the lug connection on equipment body gas pitcher for the inside gas pressure of monitoring equipment and make the warning and protect the shutting, must demolish protection device from the body gas pitcher during the check-up, repack after the check-up again, not only the step is loaded down with trivial details, if sealed pad atress is inhomogeneous during repack moreover, can have serious gas leakage hidden danger, after the dismouting many times, it is out of shape that confining bolt and flange are probably taken place to warp very much, influences the safe operation of equipment.
Based on this, the utility model designs an improved gas pressure warning blocking device to solve the above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a modified gas pressure warning blocking device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the improved gas pressure alarm locking device comprises an inflating equipment body gas tank and a gas pressure protection device, wherein the inflating equipment body gas tank and the gas pressure protection device are connected through a T-shaped three-way valve.
Preferably, the three-way valve comprises a connection port A, a connection port B and a connection port C.
Preferably, the connector A is connected with the inflating equipment body, the connector B is connected with the gas pressure protection device, and the connector C is connected with the detector.
Preferably, the detector detects the gas pressure protection device.
Preferably, a valve switching handle is arranged on the three-way valve.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model is not only novel structure, can carry out the gas flow to improve according to the actual installation condition in scene, design benefit only needs to increase one set of T type three way valve, and is with low costs, and it is convenient to maintain, is applicable to various inflation equipment's pressure alarm device, and it is very convenient to use, has high spreading value.
