Description
Technical field
Patent of the present invention relates to a kind of two six-way transfer valves, and the duty for pressure-adjustable type suspended load sampler switches.
Background technology
Development along with national economy, soil erosion and improvement of the ecological environment refer in important agenda, accurately collecting hydrologic and silt data, the decision-making for soil erosion and environmental improvement and flood control department provides sediment bypassing data accurately, has Great significance.
Collect hydrologic and silt data information it is crucial that accurately and in time gather the rivers water sample containing silt, 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, such as JL-1 type, LSS type；Threeway sampler, such as JL-2 type, AYX many cabins type, FS type, U.S.'s USP61 type, USP63 type；Four-way sampler, such 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-adjustable type suspended load sampler (hereinafter referred to as sampler) is the instrument for the river containing silt carries out tunneling boring continuous sampling in river.The purpose of pressure regulation is to eliminate unexpected perfusion phenomena, collects stable natural water-like.General method is design pressure regulating chamber in sampler, before sampling (i.e. pressure regulation state), pressure regulating chamber is intake, air in compression bin, this compression air enters water sample sampling storehouse through communicating pipe, makes the air pressure in sampling storehouse and pressure regulating chamber (i.e. sampler external water pressure) balance；Meanwhile, the water inlet of sampling tube nozzle flows out to outside sampler through bypass pipe, and silt would not be deposited in sampling conduit, can effectively solve ozzle, pipeline sand blockage problem.
Reversal valve is one of vitals of sampler, its basic function is pressure regulation and two duties of sampling of switch sampling device: namely when pressure regulation state, make sampling storehouse connect with pressure regulating chamber, it is ensured that two storehouse pressure balances, allow the water inlet of sampler tube nozzle communicate with bypass line outside outflow sampler simultaneously；When sample states, make the water inlet of pipe nozzle flow directly into sampling storehouse, 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, make the water hole on spool and passage hole corresponding with on valve body alignment, thus forming two separate passages, it is achieved the function of switch valve.There is significant deficiency in this rotary valve structure: one is that structure is complicated, and fault rate is higher, maintenance difficult；Two is the micro machine easily corrosion because of humidity, and corrosion impurity makes motor stalling after entering rotor and stator gap or burns；Three is by valve volume constraint, drives the gear teeth of gear to easily snap off, makes driving-chain destroy, thus switch valve lost efficacy；Four is that sealing is unreliable, and motor is easily intake and broken down, and reliability is low.From service condition, the problems of above-mentioned switch valve cause that sampler cannot accurately be sampled, and bring puzzlement to Hydrology department.
Summary of the invention
Patent of the present invention in order that overcome above deficiency, it is provided that a kind of simple in construction, reliable operation, failure rate is low for the six-way transfer valve of pressure-adjustable type suspended load sampler.
The object of the present invention is achieved like this:
Pressure-adjustable type suspended load sampler of the present invention includes containing water inlet pipe mouth 37 with two six-way transfer valves, exhaust pipe mouth 38, the valve gap 3 of pressure regulating chamber exhaust pipe mouth 41 and containing water outlet pipe 40, the water by-pass mouth of pipe 42, the valve body 9 of sampling storehouse exhaust pipe mouth 39 passes through bolt-connection, ceramic cartridge 8 is had between valve gap 3 and valve body 9, left and right locating piece 25, 26 and 27, 28, locating piece and valve body, valve gap coordinates still 14 up and down of ceramic cartridge 8, 20 is longitudinally fixed, left and right end cap 5, outside 2, two ends are fixed with electric magnet 6, 1, ceramic cartridge 8 is by upper, lower still 14, 20 and moving plate 17 form, moving plate 17 has water hole 29, 32, passage 30, 31, upper still 14 has water hole 21 and passage 22, 23, respectively with the inlet opening 44 on valve gap, passage 43, water hole 29 on passage 45 and moving plate 17, 32, passage 30, 31 is corresponding, upper still 14 has, on contact surface relative to moving plate 17, the blind slot 24 connected with water hole 21；Lower still 20 has respectively with the water hole 29,32 on moving plate 17, apopore 48 on passage 30,31 and valve body, water hole 50, passage 49 correspondence passage 34, water hole 33,36, on lower still 20 with the contact surface of moving plate 17 has the blind slot 35 connected with passage 34, by bolt by after valve gap and valve body connection pressed spool 8, the contact surface at moving plate 17 and upper and lower still 14,20 forms hard sealing.
All there is rectangular shoulder 16,18 moving plate 17 above and below of above-mentioned ceramic cartridge 8, the face that upper and lower still 14,20 contacts with moving plate 17 has corresponding rectangular recess 15,19 respectively, two convex shoulders of the upper and lower sealing surface of moving plate 17 16,18 coordinate with the groove 15 on upper still, the groove 19 on lower still respectively so that moving plate can relatively still along groove lengthwise movement.
The moving plate 17 of above-mentioned ceramic cartridge 8 is realized by the inner face of end cap 2,5 along the longitudinally opposed sports limiting of groove.
When the present invention works on pressure-adjustable type suspended load sampler, water-proof electromagnet 1 makes moving plate 17 relative to upper and lower still 14 by push rod 10, 20 motions, until its one end contacts with end cap, now, water hole 29 on moving plate, passage 30 respectively with the water hole 21(on upper still 14 or blind slot 24), passage 22 aligns, by the inlet opening 44 on valve gap 3, apopore 52(or 50 on valve body 9), steam vent 47(or 43 on valve gap 3), passage 49 on valve body 9 forms two independent paths and water route and gas circuit, thus realizing pressure regulation and the function of two duty switchings of sampling.The displacement of spool moving plate 17 is played position-limiting action by the inner surface of reversal valve left and right end cap 5,2, thus the hole indirectly ensured on spool moving plate 17 overlaps with corresponding hole (groove) on upper and lower still 14,20 respectively in two operating positions of reversal valve.
The present invention compared with prior art, has the advantage that
1. adopting slide-valve structure, solve rotary valve structure driving torque big, spool discontinuity, gear easily snaps off, motor easily makes moist corrosion and seals the problems such as difficulty.
2. adopt three-chip type ceramic cartridge firmly to seal, the guide frame that the groove of still moves as moving plate, simple in construction, reliable operation, sand grain on hard sealing surface can be fallen in groove simultaneously, thus avoiding boning on ceramic cartridge sealing surface, and the problem causing reversal valve card.
