Abstract
The invention discloses a kind of exhaust apparatus with fast interface.Exhaust fast interface welds together with valve seat, three sealing rings and two pads interaction cascading and is put into the upper end counterbore of valve seat in the way of three press from both sides two, bolt is threadedly attached in valve seat upper end, compression sealing ring.Valve element passes through valve seat from the bottom to top, and valve element upper end is connected by a screw with handle.O-ring is nested in O-shaped seat, and in the groove being together put into hex nut, hex nut is connected by the lower end of screw thread and valve seat.This exhaust apparatus is connected using KF clips with exhaust expansion bellowses when using.The advantage of the invention is that, exhaust fast interface easily can be connected with the exhaust expansion bellowses on exhaust equipment very much, compared with the on-link mode (OLM) of conventional rubber pipe sleeve, the fast interface of metal can more efficiently and sealing is connected with exhaust equipment securely, and exhaust efficiency is high.
Description
Technical field
The present invention relates to a kind of exhaust apparatus, and in particular to a kind of with fast interface, available for the exhaust dress vacuumized
Put.
Background technology
Exhaust apparatus plays the role of that this is important in test Dewar field, conventional exhaust apparatus and without fast interface,
Its external tapping be a metal tube, for being connected with band tubing, its connected mode is although relatively simple, but exist it is unreliable
Property, its one side easily causes slip phenomenon so that air directly pours into equipment, causes the damage of exhaust equipment；On the other hand
Because band tubing and metal tube coordinate for nested mode, its sealing is not good enough, therefore it is too low to often result in exhaust efficiency.
The content of the invention
The technical problem of solution of the present invention is：Overcome existing connection excessively simple and connect the phenomenons such as blow-by, carry
Rise exhaust efficiency.
As shown in drawings, inventing a kind of exhaust apparatus with fast interface includes exhaust fast interface 1, O-ring 2, hand
Handle 3, bolt 4, pad 5, sealing ring 6, valve element 7, valve seat 8, hex nut 9 and O-ring seat 10.Wherein：
Described valve seat 8 is the cylindrical metal part of up/down perforation in the middle of one, and it is interior spiral shell that upper end, which has at counterbore and opening,
There is a horizontal opening line, side, and lower end is external thread structure；Described exhaust fast interface 1 is the KF interfaces of standard, and it is aligned
The lateral opening hole of valve seat 8, and weld together with valve seat 8, three sealing rings 6 and two pads 5 are handed in the form of three folders two
Mutually it is laminated and is together put into the upper end counterbore of valve seat 8, bolt 4 is threadedly attached at the upper end of valve seat 8, compresses sealing
Circle 6；Valve element 7 passes through valve seat 8 from the bottom to top, and the upper end of valve element 7 is fixedly connected with handle 3 by a screw；O-ring 2 is nested in O-shaped
In ring support 10, and in the groove being together put into hex nut 9, hex nut 9 is connected by screw thread with the lower end of valve seat 8.
The beneficial effects of the invention are as follows the KF of, standard exhausts fast interface can very easily with it is outer on exhaust equipment
Bellows is connect to be connected and lock, can tight seal, raising exhaust efficiency.
Brief description of the drawings
Fig. 1 is a kind of structure chart of the exhaust apparatus with fast interface of the present invention；
In Fig. 1：1. it is vented fast interface, 2.O types circle, 3. handles, 4. bolts, 5. pads, 6. sealing rings, 7. valves
Core, 8. valve seats, 9. hex nuts, 10.O type ring supports.
Embodiment：
The present invention is further described with example below in conjunction with the accompanying drawings, in Fig. 1, the exhaust alignment valve seat 8 of fast interface 1 side
The exhaust hole on side, and weld together therewith；Interaction cascading in the form of three sealing rings 6 and two pads 5 are pressed from both sides into two with 3
And be together put into the counterbore of the upper end of valve seat 8, bolt 4 is threadedly attached in the upper part of valve seat 8, screwed in place spiral shell
Bolt 4, plays a part of compressing sealing ring 6.Valve element 7 passes through valve seat 8 from the bottom to top, and the upper end of valve element 7 passes through one piece of screw and hand
Handle 3 is fixedly connected.O-ring 2 is nested in O-ring seat 10, and in the groove being together put into hex nut 9, hex nut 9 leads to
The lower end that screw thread is crossed with valve seat 8 is connected.
