Abstract
A rot proof glass seal pipe consists of a pipe and a seal cover. The seal cover includes an outer cover and an inner plug, which are combined together and generally thread connected. The inner wall of the outer cover and the outer edge of the pipe top are provided with connecting threads, which are to the opposite in turning direction. The inner plug can be a cone with the small end inserted into the pipe, or a cylinder with 2 to 3 rounds of peripheral flange on the outer surface. The inner plug is made of polytetrafluror-ethylene. The outer cover and the pipe of the utility model are reliably connected; the inner plug is held down by the outer cover and inserted into the pipe, with good tightness. When the test pipe is heated, the inner plug puffs up and the tightness is better. The inner plug has advantages of good elasticity, corrosion resistance, no aging and long service life. The utility model solves the technical problems of unreliable sealing and unsafety existing in the current ground type and Edison type seal pipes.
Description
Technical field
The utility model relates to a kind of glass capsulation pipe fitting, especially for the Anti-corrosion glass sealing test tube of analytical instrument.
Background technology
At present, employed sealed tube generally has two kinds in the conventional analysis test: glass ground joint formula sealed tube and glass threaded sealing pipe, both constitute by body and seal cover.The former seal cover is the glass capsulation plug, when test tube need heat since invisible spectro air pressure raise can be with sealing-plug jack-up, and can't play sealing function, even solution take place and high-temperature gas overflows the danger of hurting sb.'s feelings; The latter's seal cover is the gland that has rubber sheet gasket, links to each other with body by screw thread, and when intraductal atmospheric pressure was higher, rubber sheet gasket still had the possibility of gas leakage, in addition, has also that rubber sheet gasket easily wears out, easily comes off, the shortcoming of antiseptic property difference.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, and the Anti-corrosion glass sealed tube of a kind of good airproof performance, safe and reliable, long service life is provided.
The technical solution of the utility model is: the Anti-corrosion glass sealed tube is made of body, seal cover, and seal cover comprises enclosing cover and Nei Sai, and both combine, and the mouth of pipe outer rim of enclosing cover inwall and body has connecting thread, and interior plug is anticorrosion elastomer.
Plug is threaded with enclosing cover in above-mentioned, and this screw thread is opposite with the connecting thread rotation direction of enclosing cover, body; Interior plug can be cone, and the cone small end stretches to body, also can be cylinder, and its outer surface has 2～3 road peripheral convex hoops; The material of interior plug is a polytetrafluoroethylene (PTFE).
Adopt technique scheme, enclosing cover is threaded with body, and is very reliable; In plug be cone-shaped or cylindric with protruding hoop, compress by enclosing cover and stretch in the pipe, good airproof performance, when test tube heated, certain expansion also took place in interior plug, better tightness.And interior plug adopts polytetrafluoroethylene (PTFE), good springiness, corrosion-resistant, difficult aging, long service life.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, the utility model is by body 3 and comprise that the seal cover of enclosing cover 1, interior plug 2 constitutes.Enclosing cover 1 and Nei Sai 2 are threaded, and enclosing cover 1 also is threaded with the mouth of pipe of body 3, and two thread rotary orientations are opposite, in case in unloading when covering plug from outside cover and come off.Interior plug is cone, and small end puts in body, adopts polytetrafluoroethylene (PTFE) to make.
Claims (5)
1, a kind of Anti-corrosion glass sealed tube is made of body, seal cover, it is characterized in that seal cover comprises enclosing cover and Nei Sai, and both combine, and the mouth of pipe outer rim of enclosing cover inwall and body has connecting thread, and interior plug is anticorrosion elastomer.
2, by the described Anti-corrosion glass sealed tube of claim 1, it is characterized in that Nei Sai is threaded with enclosing cover, this screw thread is opposite with the connecting thread rotation direction of enclosing cover, body.
