For improving the high temperature resistant and decay resistance of sampling valve, above-mentioned valve body, support ring, first spool and second spool are made by titanium alloy, and valve pocket is made by pure titanium.The anode ring adopts aluminium alloy to make, and can further protect other parts of sampling valve not to be subjected to marine corrosion.Above-mentioned O-ring seals is made by FFKM.
Beneficial effect of the present invention is:
The present invention adopts the frame mode of two spools, has the two-way self-tightening sealing ability, makes sampling valve that excellent sealing performance under high pressure be arranged.This sampling valve corrosion-and high-temp-resistant excellent performance helps improving fidelity of thermal water samples.Sampling valve relies on linear drives to open, and closes automatically after external motivating force is cancelled, and has increased the convenience that uses at the deep-sea.

Embodiment
Further specify the present invention below in conjunction with accompanying drawing.
With reference to Fig. 1, the high-temperature high-pressure sampling valve that is used for the deep-sea of the present invention comprises the spring cavity 12 of valve body 3 and coaxial cable device, between valve body 3 and the spring cavity 12 baffle plate 8 is arranged, inlet 5 and liquid outlet 21 are arranged on the valve body 3, support ring 4 and valve pocket 18 are installed in the valve pocket, the radial hole 22 that communicates with liquid outlet 21 is arranged on the support ring 4, the radial hole 6 that communicates with inlet 5 is arranged on the valve pocket 18, valve pocket 18 is along being circumferentially with two O- ring seals 7,20, first spool 19 is housed in the valve pocket, one end of first spool 19 has second spool 2 of coaxial cable device with it, the other end passes through plate washer 8 and stretches in the spring cavity 12, first spool 19 and valve pocket 18 in nearly plate washer one side have the half slot that equates along the aperture of axis direction, groove is built-in with place kick 16, play relatively rotating between restriction first spool and the valve pocket, have radial direction through hole 11 on the wall of spring cavity 12, first spool 19 is along being circumferentially with O-ring seals 17, second spool 2 is along being circumferentially with O-ring seals 1, spring base 14 and back-moving spring 10 are arranged in the spring cavity 12, one end of back-moving spring 10 props up spring cavity 12, the other end props up spring base 14, spring base 14 end faces are connected with anode ring 9 with engage thread, connecting link 15 passes the axial center hole of spring base 14, the one end links to each other with first spool 19, and the other end links to each other with spring base 14 by nut 13.
Above-mentioned valve body 3, support ring 4, first spool 19 and second spool 2 are made by titanium alloy, and valve pocket 18 is made by pure titanium.Anode ring 9 is made by aluminium alloy.O- ring seals 1,7,17 and 20 is made by FFKM.
The high-temperature high-pressure sampling valve that is used for the deep-sea is divided into three processes when work:
1) before the sampling, sampling valve is in closed condition, first spool 19 is being set up sealing under the effect of back-moving spring 10 and between the valve pocket 18, second spool 2 is pushed down first spool 19 under the seawater pressure effect, further increased the sealing force between first spool 19 and the valve pocket 18, and along with the rising sealing force of seawater pressure is big more.
2) in sampling process, an external motivating force acts on the nut 13, and promotes first spool 19 to left movement, opens sampling valve, and fluid enters from inlet 5, through via hole 6 and 22, enters follow-up sampling cylinder from liquid outlet 21 at last.
3) after sampling is finished, cancel the external motivating force that acts on the nut 13, first spool 19 is set up sealing with valve pocket 18 again under the effect of back-moving spring 10, and sampling valve cuts out.In the removal process of sample devices, sampling valve with sample devices from the seabed toward hydrocratic motion, the pressure of seawater reduces gradually on every side, and the sampling cylinder pressure inside remains unchanged, under the effect of inside and outside differential pressure, second spool 2 is crushed on the valve body 3, and first spool 19 further is pressed on the valve pocket 18, inside and outside differential pressure is big more, and sealing force is also big more.Therefore, no matter before sampling or after sampling, the sealing force between first spool 19 and the valve pocket 18 all increases along with the rising of pressure, has increased the reliability of sealing.
