Abstract
The utility model provides a device for checking the airtightness of a control unit assembly of an automatic thermal insulation gas-burning rice pot, comprising an air source, an on-off valve, a conduit, a t-piece, a small water tank, a glass tube electric contact wiring and an electronic control circuit. By the pressure drop produced by the gases leaked by a checking piece, the device makes an electric contact in a water pipe pressure gauge trigger the electronic control circuit. Results are displayed by sound and light, and the air tightness of the checked piece can be detected exactly. The utility model can be used for a fuel gas device, used for checking other products in which the air tightness is required, and used on an industrial automatic control line.
Description
The utility model relates to the device that a kind of automatic heat preserving Gas-burning rice pot control part assembly impermeability detects.
The control part assembly is the critical component of automatic heat preserving Gas-burning rice pot air feed control, and main valve, main fiery switch are arranged for it and gas is chewed, low baking temperature switch and gas are chewed and the air feed vernier adjustment knob, complex structure, and impermeability requires very high.Be with after the valve body assembly ventilation in the detection, brush soap lye or put into water and observe and have or not gas to leak that this detection method but has caused its parts corrosion to influence the quality of product accurately and reliably.
The purpose of this utility model provides a kind of straight-through water pipe or U type pipe pressure meter electric contact trigger control circuit, and acousto-optic shows the device of testing result, can prevent the corrosion of measured piece effectively, and can realize the robotization that detects.
The utility model is in the airtight gas circuit of the air pressure of regulation, the pressure drop that measured piece produces when the gas leakage occurring, electric contact in straight-through water pipe (or the U type pipe) pressure gauge is triggered, this shows testing result than device and logical circuit with acousto-optic voltage, thereby guarantees the effect directly perceived and the accuracy requirement of detection.
The utility model only needs measured piece is communicated in same gas circuit with the straight-through water pipe that electric contact is arranged (or U type pipe) pressure gauge, break-make by the valve air feed, in official hour, can automatically show testing result, so it is simple in structure, versatility is good, and can be widely used in other combustion gas tools and have on the product detection line and industry automatic control line that impermeability requires.
The concrete structure of utility model is drawn by following examples and accompanying drawing thereof.
Fig. 1: the structure diagram (control automatically, pneumatic control and mechanical part are not drawn) that is this device.
Fig. 2: the electricity reason figure that is this device.
Below in conjunction with Fig. 1: describe details and working condition in detail according to the concrete device that the utility model proposes.
The source of the gas of examination criteria＜1〉through the valve of high-air-tightness,＜2 〉, by threeway,＜3〉and conduit,＜4〉connection,, make detected member,＜5 〉, with by water tank,＜6 〉, glass tube,＜7 〉, the electric contact that can transfer up and down,＜8 〉, the pressure ' power meter of combination communicates in same gas circuit.Behind each air feed, Shuttoff Valve＜2 〉, if detected member＜5〉there is gas to leak, in water tank＜6〉and glass tube＜7 in the pressure drop that produces, make the water surface leave electric contact＜8 〉, and trigger by pressing this than device and logical circuit＜9, acousto-optic＜10〉show that detected member has the result of gas leakage, relay＜11〉action simultaneously, to control other topworkies.
(U type pipe＜12〉can replace＜6＜7〉part).
Claims (4)
1, at the pressure sensing of controlling automatically, the bubble-tight device of testing product particularly, but this device have valve＜2 of a break-make＞, threeway,＜3＞, conduit,＜4＞, connect detected member,＜5＞, water tank,＜6＞, glass tube,＜7＞, electric contact,＜8＞, in same gas circuit, it is characterized in that gas circuit middle water level electric contact＜8＞be connected with control circuit.
2, device according to claim 1 is characterized in that glass tube＜7〉the middle water level lifting, make electric contact＜8〉break-make, control voltage this than device and logical circuit.
