Abstract
The utility model provides a quantitative sampling valve, it is installed on the branch road of liquid conveying pipe, to the liquid quantitative sampling on the branch road. The valve consists of valve body, valve core, metering pipe, joint, etc. the valve body and the valve core are plunger matching parts, the valve core has ring slot and straight slot corresponding to the passage port in the valve body, and the valve core has key slot matching the key in the support hole. The valve has the advantages of reliable operation, long service life, good sealing performance and high temperature and pressure resistance (the temperature can reach 300 ℃ and the pressure can reach 2 PMa).
Description
The utility model provides a kind of quantitative sampling valve, and it is installed on the branch road of liquid conducting pipes, and the liquid quantitative in the branch road is taken a sample.
The existing quantitative sample valve, GV6-02 rotary valve as the production of Beijing Orient scientific instrument factory, its valve body is made with metal material, taper valve core is made with nylon (teflon), rotational valve core can change path, spool and pull bar fuse, regulate conical surface gap (spool male cone (strobilus masculinus) and valve body inner conical surface) by pull bar and guarantee sealing, its weak point is that spool is not wear-resisting, serviceable life is short, poor and the non-refractory of sealing (can not above 150 ℃) is if will use the palpus heating/cooling device under hot environment.The QH-6 ball valve produced of this factory and for example, its complex structure, spool is spherical, and valve body is cylindrical, and the upper end of each O-ring seal contacts with the sealing of the face of cylinder of valve body, its lower end contacts with the ball face sealing of spool again simultaneously, the processing of parts, assembly difficulty is big, be difficult to guarantee sealing, just leaks when pressure is 0.2MPa, though valve body, spool are metal material, but the airtight and watertight padding at two ends still is a polytetrafluoroethylmaterial material, exists equally the unconformable problem of hot environment.
The purpose of this utility model is to provide the quantitative sampling valve that a kind of long service life, good airproof performance, quantitative sampling range of adjustment are wide, can adapt to high temperature, hyperbaric environment.
The purpose of this utility model is achieved in that the quantitative sampling valve, by valve body, spool, quantity tube, parts such as joint are formed, all make with metal material, valve body and spool are plunger matching parts, several passwaies are arranged on the valve body, have on the spool can be corresponding with the passway annular groove (being the groove of radial direction) and straight trough (being the groove of axial direction), as 8 passwaies are arranged on the valve body, 4 annular grooves and 4 straight troughs are arranged on the spool, their distribution situation is: the 2nd, two straight troughs that are communicated with are with it arranged on 4 each annular grooves of annular groove, and a left side, right angled distribution is as 180 °.Convex shoulder has the key in the hole on keyway and the support I to match on the spool.
Advantage of the present utility model is: this valve arrangement is simply compact, and reliable operation, life-span are long, good airproof performance (refer to each road do not gang up, do not leak).High temperature high voltage resistant (temperature can reach 300 ℃, and pressure can reach 2MPa), spool and valve body are made with metal material, and be even part, need not use seal, valve body and be installed between the support at its two ends and also need not use seal, amount of parts is few, and the good manufacturability of processing, assembling.This valve body is long-pending little, and quantitatively oil pipe can be shorter, also can be longer, and quantitatively range of adjustment is wide.

In conjunction with the accompanying drawings, embodiment of the present utility model is further described.The quantitative sampling valve is made up of parts such as valve body, spool, quantity tube, joints.Valve body (9) is fabricated to a pair of plunger matching parts with spool (10) with metal material, 8 access openings are arranged on the valve body (9), have on the spool (10) can be corresponding with access opening 4 annular grooves (being the groove of radial direction) and 4 straight troughs (being the groove of axial direction), Fig. 5 is seen in the distribution of annular groove and straight trough, from the left end number, 1st, do not have straight trough on 3 annular grooves, on the 2nd, 4 each annular groove of annular groove two straight troughs that are communicated with annular groove are arranged, and 180 ° of distributions of left and right one-tenth.On the convex shoulder of spool (10) left end two keyways are arranged, match, spool (10) can only be moved axially in valve body (9) lining, can not radially rotate with two keys in support I (12) endoporus.Support I, II (12,11) are equipped with in the two ends of valve body (9), and retracing spring (14) also is equipped with in support I (12) lining, and be tight with nut (13) lid.Quantitative oil pipe (17) is housed between port (1), (5), tracheae (18) is housed between port (3), (8); (15) be joint, (16) are seal.The course of action that this valve is quantitatively got oil is such: when not taking a sample during this valve original state, port (1) is communicated with (8) with (6), (7) with (4), (5) with (2), (3), oil sample from delivery pipe through oil inlet pipe to port (2), be full of quantity tube (17) through port (1) again, then through port (5), (6) and scavenge pipe flow back in the conveyance conduit, pressurized air enters from port (4), flow out through port (3), tracheae (18), port (8), (7).External force promotes spool (10) left from the right-hand member end, after moving axially a certain amount of distance, port (1) disconnects with (7) with (8), (4) with (6), (7) with (4), (5) with (2), (3), obtain a quantitative oil sample in the quantity tube (17) originally, port (1) is connected by the annular groove and the straight trough of spool (10) with (7) with (4), (5), pressurized air enters into port (1) from port (4), quantitative oil in the quantity tube (17) is blown out through port (5), (7), and this promptly obtains quantitative oil.Quantitatively oil is how much relevant with length with the caliber of quantity tube (17), can select or change quantity tube (17) as required and regulate quantitatively.
