Abstract
The utility model relates to a check joint device, in particular to a disassembly-free check joint of a density relay. The technical scheme provided by the utility model is that: the check joint mainly consists of a three-way valve body, a needle valve handle, a density relay, a pipeline joint, a needle valve, a sealing gasket and a self-sealing joint, wherein an air chamber is formed in the cavity of the three-way valve body; the density relay is fixed on the top of the three-way valve body, the self-locking joint is fixed on the lower part of the three-way valve body, and the needle valve is arranged on one of the left side and the right side of the three-way valve body, and the other one of the left side and the right side of the three-way valve body is connected with the pipeline joint; and the needle valve handle is fixed outside the needle valve. The check joint has the beneficial effects that: check work of the density relay and gas charging work of equipment of an SF6 electric switch are greatly facilitated, so that electric overhauling personnel can conveniently check or replace the SF6 gas density relay without disassembling a joint seat; and meanwhile, the equipment can be vacuumed and charged through the joint, so that convenience is brought to the operation of the electric overhauling personnel, and the working efficiency can be greatly increased.
Description
One, technical field:
The utility model relates to a kind of checking joint device, and particularly a kind of density monitor exempts to dismantle checking joint.
Two, background technology:
SF6 gas has dielectric strength height, characteristics that arc extinction performance is good, is the first-selected dielectric of present high-tension apparatus, in order to ensure the high-tension apparatus safe operation, must carry out strict monitoring to parameters such as the density of SF6 gas, water content.The SF6 gas density relay is used for high voltage electric equipment exactly, and to a kind of device that the SF6 gas density is monitored, it in time sends alarm signal, block signal at the gas leakage situation that occurs in the electric equipment.Can in time, effectively avoid the generation of accident, guarantee the safe operation of high voltage electric equipment.But, be installed in on-the-spot SF6 gas density relay because often be failure to actuate, As time goes on, phenomenons such as dumb, contact loose contact can occur moving, the temperature-compensating performance that also can cause because of the influence of environmental condition that has reduces, and causes the density monitor malfunction.For this reason, DL/T596-1996 " power equipment preventive trial rules " regulation will regularly be carried out verification to the SF6 density monitor, SF6 electric equipment model is numerous at present, the gas link circuit has nothing in common with each other, but density monitor is essentially two kinds of situations with the gas circuit that is connected of its body, if the junction is a non-return valve, then must density monitor be pulled down and test from non-return valve; If the junction is an interface, then must application have a power failure, disconnect with the body valve closing and with pipeline and valve then, pull down density monitor again and test.Simultaneously, because sealing gasket and fluid sealant are all adopted in the sealing between most of density monitors and non-return valve or the interface,, cause the SF6 electric equipment that gas leakage slowly takes place if often dismounting certainly will cause sealing gasket and fluid sealant damage.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of density monitor to exempt to dismantle checking joint.
Its technical scheme is: mainly be made up of triple-valve body, needle-valve handle, density monitor, pipe joint, needle-valve, sealing gasket, self-enclosed joint, the triple-valve body inner chamber is provided with air chamber, triple-valve body top constant density relay, self-enclosed joint is fixed in the bottom, side in the left and right sides of triple-valve body is provided with needle-valve, opposite side connecting line joint, the needle-valve outside is the needle-valve handle fixedly.
Above-mentioned density monitor, pipe joint, needle-valve, self-enclosed joint communicate with the air chamber of triple-valve body respectively.
Outside fixing seal mat in the above-mentioned self-enclosed joint.
Above-mentioned density monitor one side fixed contact pull box.
The beneficial effects of the utility model are: the density monitor verification work and the equipment inflation work that greatly facilitate the SF6 electric switch, make the electric power overhaul personnel need not dismantle plinth, just can make things convenient for verification or replacing to the SF6 gas density relay, simultaneously can also vacuumize and inflate equipment by joint, for electric power overhaul personnel's operation brings convenience, can increase work efficiency greatly.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: triple-valve body 1, needle-valve handle 2, density monitor 3, contact lead box 4, air chamber 5, pipe joint 6, needle-valve 7, sealing gasket 8, self-enclosed joint 9.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model mainly is by triple-valve body 1, needle-valve handle 2, density monitor 3, pipe joint 6, needle-valve 7, sealing gasket 8, self-enclosed joint 9 is formed, the inside of triple-valve body is provided with SF6 air chamber 5, triple-valve body 1 top constant density relay 3, self-enclosed joint 9 is fixed in the bottom, side in the left and right sides of triple-valve body 1 is provided with needle-valve 7, opposite side connecting line joint 6, needle-valve 7 outsides are needle-valve handle 2 fixedly, outside fixing seal pad 8 in the above-mentioned self-enclosed joint 9, above-mentioned density monitor 3, pipe joint 6, needle-valve 7, self-enclosed joint 9 communicates above-mentioned density monitor 3 one side fixed contact pull boxes 4 with the air chamber 5 of the inner chamber of triple-valve body 1 respectively.
This device is by the interface to density monitor, rationally transform the joint, making it need not dismantle density monitor just can safety, easily it is tested and change, when the test density relay, come isolation circuit breakers body air chamber and density monitor air chamber by control to two valves in the improved density monitor joint, form an independent verification air chamber, this air chamber can be charged and discharged freely by the gas of verification, thereby realize that not dismantling density monitor carries out at X-ray inspection X, do not influence the SF6 electric equipment is carried out tonifying Qi and the test of little water, not only solved the problem that the SF6 density monitor can not carry out periodic inspection, and avoided unnecessary power failure, improved reliability to user's power supply.
