Description

Improved gas pressure alarm locking device

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.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

FIG. 1 is a schematic view of the present invention in normal use;

fig. 2 is a schematic diagram of the detection of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides an improved gas pressure alarm locking device, which comprises: the gas tank 1 of the gas-filled equipment body is connected with the gas pressure protection device 3 through a T-shaped three-way valve 2.

Wherein, three way valve 2 includes A connector 21, B connector 22 and C connector 23, is connected between A connector 21 and the gas tank 1 of inflation equipment body, and B connector 22 is connected with gas pressure protection device 3, and C connector 23 is connected with detector 5, and detector 5 detects gas pressure protection device 3, is equipped with valve switching handle 4 on three way valve 2, is convenient for change three way valve 2's opening flow direction to change gaseous flow direction.

The specific working principle is as follows:

when the gas tank is normally used, the gas tank 1 of the inflation equipment body is directly communicated with the gas pressure protection device 3 (namely, the connection port A21 and the connection port B22 are communicated), the other connection port (namely, the connection port C23) of the three-way valve 2 is in a closed state, and the gas pressure protection device 3 detects and protects the gas in the gas tank 1 of the inflation equipment body, as shown in fig. 1; when the gas pressure protection device 3 needs to be checked, the position of the T-shaped three-way valve 2 is converted through the switching handle 4, the A interface 21 of the gas tank 1 connected with the inflating equipment body is closed, the gas pressure protection device 3 is communicated with the C interface 23 at the moment, the gas pipe of the detector 5 can be connected to the C interface 23 of the three-way valve for checking, and the communication state of the position of the three-way valve 2 to the A, B interface is recovered after detection is finished
