Abstract
The utility model belongs to the technical field of chemical equipment, and particularly relates to a closed-type sample connection and a matched leakage-preventing sampler. The technical scheme of the closed-type sample connection and the matched leakage-preventing sampler is that the closed-type sample connection comprises an inner opening and an outer opening, the inner opening and the outer opening are connected with a chemical reservoir vessel, a reducer pipe body is connected between the inner opening and the outer opening, the size of a reducer pipe opening beside the inner opening is greater than the size of the reducer pipe opening beside the outer opening, a metal ball is placed inside the reducer pipe body, a seal ring I is arranged between the metal ball and the reducer pipe body, and a seal ring II is mounted on the inner side of the reducer pipe body closed to the inner opening. The matched leakage-preventing sampler comprises a sampling needle tube and a sleeve body which is disposed on the outer side of the middle portion of the sampling needle tube. The closed-type sample connection and the matched leakage-preventing sampler solve the problem of leakage due to spacer aging or damage so as to avoid safety accidents.
Description
Technical field
The utility model belongs to technical field of chemical, relates in particular to closed sample tap and supporting anti-leak ST.
Background technology
The closed sample tap of present many chemical industry producer chemical industry reservoir vessel is that a plug is used the rubber sheet gasket shutoff; ST is a syringe needle, and the other end of syringe needle connects sampling jar, all uses the rubber sheet gasket of needle pierces sealing during closed sampling; Syringe needle penetrates the gasket seal of sampling jar; Utilize pressure reduction to take a sample, material just gushes out from pin hole, and other one of pin is connected the sampling jar the inside.Rubber sheet gasket because aging or material to rubber sheet gasket corrosion add syringe needle and rubber sheet gasket is repeatedly stung hit the back and damage easily, cause material from leakage, and chemical material is combustible and explosive articles mostly, bring potential safety hazard to production.
Summary of the invention
The purpose of the utility model is, overcomes the deficiency of prior art, and closed sample tap and supporting anti-leak ST on a kind of chemical material reservoir vessel are provided.It is aging to have solved pad, perhaps damages the leakage problem that causes, and avoids security incident to take place.Especially be applied in the rare-earth isoprene rubber rectification process.
For solving the problems of the technologies described above; The technical scheme of the utility model is: closed sample tap and supporting anti-leak ST, and said closed sample tap comprises internal orifice, the collar extension that is connected with the chemical industry reservoir vessel, is connected with the reducing body between internal orifice and the collar extension; The orifice reducer of interior oral-lateral is greater than the orifice reducer of outer oral-lateral; In said reducing body inside metal ball is arranged, between metal ball and reducing body, O-ring seal I is arranged, O-ring seal II is arranged in reducing body inboard near internal orifice; Said supporting anti-leak ST comprises sampling needle tubing and the body that is positioned at the outside, sampling needle tubing middle part.There is plug at the collar extension place.The reducing body can not skid off metal ball, metal ball with become that O-ring seal I makes metal ball closely contact with the reducing body between the body, prevent the material leakage; In the time of can preventing that near the O-ring seal II of internal orifice chemical material reservoir vessel internal pressure from reducing, metal ball gets into internal tank, causes unnecessary trouble; During sampling, take off the plug of collar extension, twist into the body of ST; The sampling needle tubing jack-up metal ball of ST, at this moment material flows into sampling jar through the sampling needle tubing; By plug and metal ball sealants, the assurance material can not revealed when not taking a sample; Said plug and collar extension when not taking a sample, guarantee that plug can not come off for spinning, and the cover external has screw thread, and body closely is connected with collar extension, when sampling, can not make the ST landing because of the pressure differential of inside and outside.
The beneficial effect of the utility model is: closed sample tap and supporting anti-leak ST; Said closed sample tap comprises internal orifice, the collar extension that is connected with the chemical industry reservoir vessel; Be connected with the reducing body between internal orifice and the collar extension, the orifice reducer of interior oral-lateral has metal ball greater than the orifice reducer of outer oral-lateral in said reducing body inside; Between metal ball and reducing body, O-ring seal I is arranged, O-ring seal II is arranged in reducing body inboard near internal orifice; Said supporting anti-leak ST comprises sampling needle tubing and the body that is positioned at the outside, sampling needle tubing middle part.Simple in structure, easy to use, can solve the aging problem of prior art pad, prevent to damage the leakage of the chemical material that causes, avoid security incident to take place.
