Description
Technical field
The utility model patent relates to a kind of two six-way transfer valves, and the duty for pressure-adjusting type suspended load sampler switches.
Background technology
Along with the development of national economy, soil erosion and improvement of the ecological environment refer in important agenda, accurate collection hydrologic and silt data, for the decision-making of soil erosion and environmental improvement and flood control department provides sediment bypassing data accurately, has Great significance.
The key of collecting hydrologic and silt data information is accurate and rivers water sample that is that gather in time containing silt, and this is a great problem that Hydrology department faces for a long time.In order to meet the needs of river load water sampling, domestic relevant department constantly develops and improves silt sampling instrument, successively have developed two-way sampler, as JL-1 type, LSS type; Threeway sampler, as JL-2 type, AYX many cabins type, FS type, U.S. USP61 type, USP63 type; Four-way sampler, as JL-3 type, JX type etc.There is pressure regulation and last long and ozzle sand problem in two-way sampler, threeway sampler solves pressure regulation and lasts long problem, and four-way sampler substantially solves pressure regulation and lasts long and ozzle sand problem.
Pressure-adjusting type suspended load sampler (hereinafter referred to as sampler) is the instrument for carrying out tunneling boring continuous sampling in river to the river containing silt.The object of pressure regulation eliminates unexpected perfusion phenomena, collects stable natural water-like.General method designs pressure regulating chamber in sampler, before sampling (i.e. pressure regulation state), pressure regulating chamber is intake, air in compression bin, this compressed air, through entering water sample sampling storehouse communicating pipe, makes the air pressure in sampling storehouse and pressure regulating chamber (i.e. sampler external water pressure power) balance; Meanwhile, the water inlet that sampling pipe is chewed flows out to outside sampler through bypass pipe, and silt would not be deposited in sampling conduit, effectively can solve ozzle, pipeline sand blockage problem.
Reversal valve is one of vitals of sampler, its basic function is pressure regulation and sampling two duties of switch sampling device: namely when pressure regulation state, sampling storehouse is communicated with pressure regulating chamber, ensure two storehouse pressure balances, allow sampler tube chew simultaneously and to communicate with bypass line into water and flow out outside sampler; When sample states, pipe is chewed and directly flows to sampling storehouse into water, make the air in sampling storehouse discharge sampler through reversal valve and gas exhaust piping simultaneously.
File 1(CN200410081315) and file 2(CN200420105206) disclose a kind of actuating valve for suspended sand sampler and spool, it is characterized in that driving valve core rotation with micro machine by gear reduction unit, rely on the positioning action of alignment pin and spacer pin on gear and valve gap, the hole making the water hole on spool corresponding on valve body with passage is aimed at, thus the passage that formation two is separate, realize the function of switch valve.There is significant deficiency in this rotary valve structure: one is complex structure, and fault rate is higher, maintenance difficult; Two is micro machine easily corrosions because of humidity, and corrosion impurity makes motor stalling or burns after entering rotor and stator gap; Three is that the gear teeth of driven wheel easily fracture, and driving-chain is destroyed by valve volume constraint, thus switch valve lost efficacy; Four is that sealing is unreliable, and motor is easily intake and breaks down, and reliability is low.From service condition, the problems of above-mentioned switch valve cause sampler accurately to sample, and bring puzzlement to Hydrology department.
