Abstract
A kind of non-return valve flow detector, is fixedly installed four guide pillars, is fixedly connected with a compression cylinder in the center of upper mounted plate between upper mounted plate and bottom plate corner; Upper mounted plate divides into an installing plate; Cylinder axis is fixedly connected with installing plate through upper mounted plate; The bottom of installing plate is fixedly connected with four guide pin bushings, and four guide pillars are through guide pin bushing; Compression cylinder can drive installing plate up and down along guide pillar direction; Compact heap is fixedly connected on the center of installing plate bottom, with compression cylinder coaxial cable; Bottom plate is fixedly connected with part and lays platform, shutoff cylinder; Plugging block side is threaded the cylinder axis of shutoff cylinder, and another side is workplace, and workplace center has L-type gas circuit, and the gas circuit other end is communicated with source of the gas; The plugging block other end arranges O-ring seal, and diameter and the test product of O-ring seal match.The utility model before compressor final assembly, can simulate the non-return valve duty at compressor operating environment.
Description
Technical field
The utility model a kind ofly detects the device of non-return valve in specific pressure difference environment down-off, designs the improvement to its structure especially.
Background technology
Non-return valve is provided with between existing compressor internal high pressure chamber and low pressure chamber.
When compressor shutdown for preventing gases at high pressure from impacting motor, the gas being in the high pressure chest on compressor top is back to the low pressure chamber of compressor lower end with form slowly by non-return valve.Therefore all have the traffic requirement under particular pressure when compressor design to non-return valve.For protecting the motor serviceable life of compressor, need to detect the flow of compressor non-return valve under operating pressure.After compressor is mounted to complete machine, the test working of complete machine is detected at present.Its shortcoming is, after assembling complete machine, test-run a machine is surveyed, if detect bad, can cause a large amount of maintenance costs.
Summary of the invention
The utility model is the shortcoming overcoming the existence of above-mentioned prior art, provides a kind of non-return valve flow detector of simple and fast.
The utility model is achieved in that a kind of non-return valve flow detector, is fixedly installed four guide pillars, is fixedly connected with a compression cylinder in the center of upper mounted plate between upper mounted plate and bottom plate corner; Upper mounted plate divides into an installing plate; Cylinder axis is fixedly connected with installing plate through upper mounted plate; The bottom of installing plate is fixedly connected with four guide pin bushings, and four guide pillars are through guide pin bushing; Compression cylinder can drive installing plate up and down along guide pillar direction; Compact heap is fixedly connected on the center of installing plate bottom, with compression cylinder coaxial cable; Bottom plate is fixedly connected with part and lays platform, shutoff cylinder; Plugging block side is threaded the cylinder axis of shutoff cylinder, and another side is workplace, and workplace center has L-type gas circuit, and the gas circuit other end is communicated with source of the gas; The plugging block other end arranges O-ring seal, and diameter and the test product of O-ring seal match.During test, tested part and shutoff cylinder coaxial line.
The utility model before compressor final assembly, can simulate the non-return valve duty at compressor operating environment, and detects the demand whether it meets technique.Avoid test-run a machine test after mounting to detect bad, cause a large amount of maintenance costs.The utility model structure is simple, easy to detect.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Structural representation when accompanying drawing 2 is the utility model detection parts.
1 compression cylinder, 111 cylinder axis, 2 upper mounted plates, 3 compact heap 4 installing plates, 5 guide pin bushings, 6 tested parts, 7 platforms, 8 guide pillars, 9 bottom plates, 10 shutoff cylinders, 11 cylinder connecting links, 12 plugging block, 13 O-ring seals, 14 non-return valve blocks, 15 check valve hole, 16 gas circuits.
Embodiment
Between upper mounted plate 2 and bottom plate 9 four jiaos, be fixedly installed four guide pillars 8, be fixedly connected with a compression cylinder 1 in the center of upper mounted plate 2; Upper mounted plate 2 divides into an installing plate 4; Cylinder axis 111 is fixedly connected with installing plate 4 through upper mounted plate 2; The bottom of installing plate 4 is fixedly connected with four guide pin bushings, 5, four guide pillars 8 through guide pin bushing 5; Compact heap 3 is fixedly connected on the center of installing plate 4 bottom, with compression cylinder 1 coaxial cable; Bottom plate 9 is fixedly connected with part and lays platform 7, shutoff cylinder 10; Plugging block 12 side is fixedly connected with the cylinder axis 11 of shutoff cylinder 10, and another side is workplace, and workplace center has L-type gas circuit 16, and the gas circuit other end is communicated with source of the gas; During test, tested part 7 and shutoff cylinder 10 coaxial cable.
Plugging block workplace arranges O-ring seal 13, and diameter and the test product of O-ring seal match.
Compression cylinder 1 is mutually vertical with the axis of shutoff cylinder 10.
When using the utility model, flowmeter is arranged between source of the gas and L-type gas circuit 16.Test product 6 being placed on part lays on platform 7; PVC compact heap 3 is promoted to compress product by upper compression cylinder 1, the plugging block 12 flat rubber O-ring seal 13 embedded with it promotes by shutoff cylinder 10 draft tube blocking product, pressurized air adjusts source of the gas according to the pressure of measurement demand, is injected in product by gas circuit 16; Non-return valve block 14 blows to closure state by air-flow; Check valve hole 15 leaks away pressurized air slowly, now at the flowmeter that the airintake direction of gas circuit 16 connects, can detect the leakage flow of non-return valve under regulation pressure.
