Abstract
The utility model relates to a micro oxygen filler of an oxygen bomb, which relates to auxiliary equipment of a calorimeter and comprises a two-position and three-way valve controlled by a knob screw and an air nozzle sleeve with a quick steel ball clamp device. The utility model can be quickly and fixedly clamped on an air scoop of the oxygen bomb by the quick steel ball clamp device, and pressure oxygen can be accessed into the oxygen bomb or disconnected by rotating the knob screw to move the two-position and three-way valve. The utility model has the advantages of small size, light weight and convenient operation. A test person's forced manual operation can be relieved.
Description
The utility model relates to calorimetric auxiliary device.
All kinds of combustible thermal values are measured in the oxygen bomb calorimeter usually, and its main process is that a certain amount of analytical sample is in the oxygen bomb calorimeter; Be filled with the oxygen bomb internal combustion of excess of oxygen.Therefore, oxygen bomb is calorimetric critical piece, and to the device of oxygen bomb charged pressure oxygen, promptly oxygen-ball oxygenator is one of main auxiliary device of calorimeter.Existing oxygen-ball oxygenator mostly is to rely on manual gear rack mechanism or eccentric stiffener to move oxygenator gas to chew cover or oxygen bomb, makes oxygenator valve cover be inserted in the oxygen bomb air inlet and chews, and opens gas and chews the retaining valve that puts, and makes pressure oxygen enter oxygen bomb.In whole oxygenation process, must rely on hand-power that the gas of oxygen-ball oxygenator is chewed to be locked and be pressed on the oxygen bomb air inlet and chew; This kind oxygen-ball oxygenator all compares heavy.
The purpose of this utility model is to provide a kind of miniature oxygen-ball oxygenator, to exempt the manual operations that testing crew is exerted oneself.
The utility model is realized its goal of the invention by the following technical solutions: the utility model comprises the gentle cover of chewing of two position three-way valve of knob bolts control, and gas is chewed and put device quick steel ball clamp device is arranged.Quick steel ball clamp device that relies on gas to chew to put and oxygen bomb air inlet are chewed special ring groove and the utility model can be fastened in the oxygen bomb air inlet and chew, the turning knob screw moves the two-position three way valve core can insert oxygen bomb or disconnection with pressure oxygen, thereby realizes the function of the utility model to the oxygen bomb oxygenation.
The utility model has following characteristics: owing to do not have rack-and-pinion or eccentric stiffener and heavy parts such as support, cost of products reduces (1), and volume and weight all greatly reduces; (2) exempted the manual operations that testing crew is exerted oneself; (3) easy to operate.
Accompanying drawing is a cut-open view of the present utility model.
The utility model comprises valve body 1, spool 2, O-ring seal 3,4,5,6, knob bolts 7, pipe adapter 8, tensimeter 9, upward gas is chewed cover 10, the therapeutic method to keep the adverse qi flowing downward is chewed cover 11, steel ball 12, steel ball cutting ferrule 13, spring 14, elastic spring 15.Valve body 1 middle part right-hand member has a horizontal spool blind hole, nose end has screw thread, left end has a tapped blind hole, two blind holes are communicated with by a central through hole, the top is equipped with tensimeter (9) and is communicated with horizontal spool bore, one threaded hole is arranged at the bottom, and it is communicated with horizontal spool bore by a through hole, pipe adapter 8 is anchored in the horizontal spool bore of valve body 1 right-hand member, be equipped with O-ring seal 3 in the pipe adapter 8 termination ring grooves, spool 2 is bearing pins that there is step at a middle part, an O-ring seal 4 respectively is equipped with in the step both sides, in spool 2 right-hand member bearing pin tubular stinger joints 8 holes, the left end bearing pin inserts in valve body 1 central through hole, knob bolts 7 is loaded in the valve body 1 left end screw, right side O-ring seal 4 on the spool 2 can be pressed in pipe adapter 8 end faces, last gas is chewed cover 10 and is tightened in the valve body 1 bottom screw, between be equipped with O-ring seal 5, there is through hole at the center, the hole is chewed for chewing measure-alike gas with the oxygen bomb air inlet in the lower end, and O-ring seal 6 is housed, the therapeutic method to keep the adverse qi flowing downward is chewed cover 11 and is tightened in gas by screw thread and chews and overlap on 10, the therapeutic method to keep the adverse qi flowing downward is chewed cover 11 bottom gas and is chewed the hole side several radial holes are arranged, two steel balls 12 are housed in each hole, interior steel ball can protrude from the therapeutic method to keep the adverse qi flowing downward and chew cover 11 gas and chew internal surface of hole but can not pass through, and outer steel ball is then put down the outer cylinder surface of chewing cover 11 in the therapeutic method to keep the adverse qi flowing downward, and steel ball cutting ferrule 13 sliding sleeves are chewed on the cover 11 in the therapeutic method to keep the adverse qi flowing downward, be equipped with spring 14 between the two, steel ball cutting ferrule 13 lower ends are the stepped hole of a step band gradient, under the effect of spring 14, its step angle be supported in be loaded on the therapeutic method to keep the adverse qi flowing downward chew the cover 11 terminations elastic spring 15 on.
The utility model course of work is as follows: the tracheae on the pipe adapter 8 is connected with the welding bottle reduction valve, to move on the steel ball cutting ferrule 13, this moment, steel ball cutting ferrule 13 lower end stepped holes were over against steel ball 12, then the utility model being inserted in the oxygen bomb air inlet chews, the oxygen bomb air inlet is chewed and can be promoted outer the moving of steel ball 12 and enter the therapeutic method to keep the adverse qi flowing downward fully and chew and overlap 10 and 11 gas and chew in the hole, this moment, the oxygen bomb air inlet was chewed special ring groove over against steel ball 12, loosen steel ball cutting ferrule 13, it moves down under the effect of spring 14, interior steel ball is pushed the oxygen bomb air inlet to be chewed in the ring groove, the utility model just is fastened in the oxygen bomb air inlet and chews like this, then, anticlockwise turning knob screw 7, itself and spool 2 left end bearing pins are broken away from, spool 2 moves to left under the effect of pressure oxygen pressure, spool 2 upper left side O-ring seals 4 are close with spool bore left end through hole envelope, pressure oxygen is chewed cover 10 by last gas and is entered oxygen bomb, O-ring seal 6 can prevent that pressure oxygen from chewing along the oxygen bomb air inlet and leak, according to tensimeter 9 indications, can judge oxygen bomb oxygenation degree, when oxygenation foot, clockwise turning knob screw 7, promoting spool 2 moves to right, spool 2 right side O-ring seals 4 press in pipe adapter 8 end faces, cut-out pressure oxygen enters spool bore, spool bore communicates with atmosphere by the gap of its left end through hole through between the screw thread of knob bolts 7 and valve body 1, the pressure oxygen that last gas is chewed in the cover 10 overflows, and steel ball cutting ferrule 13 is upwards lifted, and can chew from the oxygen bomb air inlet together with the utility model and take off.
