Abstract
The utility model discloses a chemical liquid pipe joint, which relates to the field of an apparatus and a device for chemical experiments. The chemical liquid pipe joint is chiefly cast by precise components. A hexagonal screw nut and a tightening leaning ring are manufactured to be integrated spanners and screw nuts which are sheathed on screw threads, and the tightening tube head are manufactured into an inclined surface, the lower end of which is provided with spiral lines. The chemical liquid pipe joint which is as an ideal chemical liquid pipe joint has the advantages of reasonable structural design, economy, high practicality, safe and convenient usage, and easy manufacturing.
Description
The utility model is a kind of chemical liquids pipe joint, relates to chemical experiment instrument, apparatus field.
At present, common chemical liquids pipe joint (as shown in Figure 1) packing tube head be straight line and lower thread sharp-pointed, cause liquid leakage and scratch the inwall soft formation that cooperates pipe fitting with it easily, moreover packing is processed into separately by ring, many one decks operational sequence uses also inconvenient.
The utility model purpose has overcome above-mentioned defective, provides a kind of and has been processed as one by ring with hexagon nut and packing, and the packing tube head is designed to the new chemical liquid pipe connection on inclined-plane.
The purpose of this utility model is achieved in that it is formed by precision casting, and circular pipe top is shaped on thread, and the wrench nut joins with it, and the bottom makes the inclined-plane with the packing tube head, is provided with spiral lamination bottom.
Advantage of the present utility model is: economical and practical, rational in infrastructure, safe ready is processed meticulously, is easy to make, and prevents leaking outside of chemical liquid.
Description of drawings:
Fig. 1 is the prior art perspective view.
Fig. 2 is the utility model structure and semi-section schematic representation.
Fig. 3 is the utility model working state schematic representation.
Among the figure: the 1st, thread, the 2nd, the wrench nut, the 3rd, the packing tube head, the 4th, bottom spiral lamination, the 5th, ring is leaned in packing, and the 6th, conjunction.
Below in conjunction with drawings and Examples the utility model is done further carefully to state.
The utility model is that precision casting forms, and is provided with thread 1 on the top of circular pipe, and wrench nut 2 suits are on it, and packing tube head 3 Bevels and lower end snail lira 4 are cast as one.
Claims (2)
1, a kind of chemical liquids pipe joint is to be made by circular pipe to be followed successively by thread, wrench nut, packing tube head and bottom spiral lamination from top to bottom, and it is characterized in that: the wrench nut is that hexagon nut and packing are made as one by ring, and the packing tube head is an inclined-plane.
2, chemical liquids pipe joint according to claim 1 is characterized in that the bottom is a spiral lamination.
