Description

A kind of accumulator inflation weldering nail special mould clamp device
Technical field
The utility model relates to fluid hydraulic pressure technical field, specifically provides a kind of accumulator inflation weldering nail special mould clamp device.
Background technology
In the fluid Hydraulic Field, most of industry requires harsh to the appearance and size of accumulator, under the constant situation of the cavity volume of accumulator, requires the diameter of accumulator and height can not exceed its installing space, and will reserve rational assemblage gap.
And present most of accumulator is inflated because of needs immediately, then the inflation terminal screw need be set, and the size that this has just strengthened accumulator is not easy to use.
Summary of the invention
The utility model is to above problem; A kind of accumulator inflation weldering nail special mould clamp device is provided, and it makes accumulator under the situation that its due inner chamber gas is not revealed, and its inflation eyelet welding is dead; Thereby strengthen its air-tightness; Omit the inflation terminal screw, dwindle the whole volume of accumulator, for the fluid hydraulic test is practiced thrift installing space.
The utility model solves the technical scheme that its technical problem adopted:
A kind of accumulator inflation weldering nail special mould clamp device; Comprise accumulator; Be arranged with special mould clamp on the accumulator, be provided with the welding connecting rod in the special mould clamp of below, the special mould clamp of top connects oil pump; Said oil pump connects hydraulic pump through three-position four-way valve, check valve, and said three-position four-way valve is connected central control cabinet with hydraulic pump.
Pipeline between three-position four-way valve and the oil pump is provided with pressure sensor and safety valve, and it is inner to be communicated with accumulator.
Be provided with compresses seal and sealing ring in the special mould clamp of below, it is respectively applied for the slit between sealing accumulator bottom and welding connecting rod and the special mould clamp inwall.
Be connected with in the special mould clamp of below and have manometric gas cylinder.
A kind of accumulator inflation weldering nail special mould clamp device of the utility model adopts convertible frock, to satisfy the needs of different size model accumulator inflation welding.Adopted the hydraulic pressure adjustable systems, made the required pressing of different size accumulator, sealing force is adjustable continuously.Adopted inflation transmission integrated, made it be charged to the situation lower seal of specified air pressure, the operation of welding connecting rod, welding by once.
A kind of accumulator inflation weldering nail special mould clamp device of the utility model; Can realize following purpose: the 1) transformational of multiple frock; The harmony of the 2) adjustability of required pressing, sealing force, 3) inflation, pressurize, welding, 4) welding of all size model is compatible.
A kind of accumulator inflation weldering nail special mould clamp device of the utility model; Selected for use convertible frock, hydraulic pressure adjustable systems, inflation transmission integrated; The welding of widening all size kind greatly is compatible, makes accumulator reduce volume, has improved the sealing of gas.
Compared with prior art, a kind of accumulator of the utility model inflation weldering nail special mould clamp device, have reasonable in design, simple in structure, safe and convenient to use, improve the gas air-tightness and reduce the characteristics of accumulator volume.
Description of drawings
Fig. 1 is a kind of structural representation of accumulator inflation weldering nail special mould clamp device.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment a kind of accumulator inflation weldering nail special mould clamp device of the utility model is done further to describe.
Shown in accompanying drawing 1; A kind of accumulator inflation weldering nail special mould clamp device comprises accumulator 1, is arranged with special mould clamp 2 on the accumulator 1; Be provided with welding connecting rod 3 in the special mould clamp 2 of below; The special mould clamp 2 of top connects oil pump 4, and said oil pump 4 connects hydraulic pump 7 through three-position four-way valve 5, check valve 6, and said three-position four-way valve 5 is connected central control cabinet 8 with hydraulic pump 7.
Pipeline between three-position four-way valve 5 and the oil pump 4 is provided with pressure sensor 9 and safety valve 10, and is communicated with accumulator 1 inside.
Be provided with compresses seal 11 and sealing ring 12 in the special mould clamp 2 of below, it is respectively applied for the slit between sealing accumulator 1 bottom and welding connecting rod 3 and special mould clamp 2 inwalls.
Be connected with the gas cylinder 14 that has Pressure gauge 13 in the special mould clamp 2 of below.
A kind of accumulator inflation weldering nail special mould clamp device use of the utility model is following:
1, selects the assembling jig according to the specification of accumulator 1, put into jig 2 to accumulator 1.
2, open central control cabinet 8; Primer fluid press pump 7, open on three-position four-way valve 5 left sides, and hydraulic oil is through check valve 6, three-position four-way valve 5; To oil pump 4; Oil pump 4 kills accumulator 1 through jig 2 fixing, and the lower surface compresses seal 11 of accumulator 1 makes the lower surface of accumulator 1 and the latter half of jig 2 form an airtight cavity.
3, open nitrogen cylinder, be charged to required specified nitrogen pressure to accumulator 1.Operation welding connecting rod 3, (sealing ring 12 and 3 sealings of welding connecting rod, when 3 operations of welding connecting rod, the latter half of jig 2 remains airtight cavity) makes the weldering nail dead the inflation eyelet welding.
4, pressure sensor 9, accumulator 1 and safety valve 10 are housed on the fluid pressure line.When being installed accumulator 1, configure the pressure limit of liquid.When reaching setting pressure, jig 2 kills accumulator 1, and accumulator 1 has stored certain liquid simultaneously.The data of pressure sensor 9 are given central control cabinet 8, and oil pump 4 stops when reaching maximum pressure, accumulator 1 pressurize, and jig 2 keeps certain function power.When fluid pressure was lower than minimum setting pressure, oil pump 4 started the above step of repetition.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
