Abstract
The utility model relates to a connecting device for air inlets of vacuum pumps. The utility model is characterized in that the connecting device is composed of a connecting sleeve barrel (1) and more than one flow dividing nozzle (4), wherein one end of the connecting sleeve barrel (1) is provided with a plurality of top threads (3) in radial arrangement; the other end of the connecting sleeve barrel (1) is integrally connected with a square flow dividing chamber (2); at least two flow dividing holes (6), the axial directions of which are vertical to each other are arranged on the flow dividing chamber (2); one flow dividing nozzle (4) with a valve (7) is installed in each flow dividing hole (6), and a funnel-shaped sealing rubber ring 5 is arranged in the connecting sleeve barrel (1).
Description
The utility model relates to a kind of vacuum pump suction port connection set.
In industries such as chemical industry and pharmacy, experimental setup in the laboratory usually needs to be connected with minipump, so that make experimental setup reach requirement of experiment, and normally used minipump is because the difference of its manufacturer, and the suction port specification of its pump has nothing in common with each other.Connection with experimental setup brings a lot of difficulties like this, and is not tight as connecting, stability difference etc., and also a pump can only be used for a cover experimental setup.
The purpose of this utility model is exactly in order to address the above problem, design a kind of connection set that can be suitable for the vacuum pump suction port of all size size, use this connection set can make vacuum pump tight more and stable, and can reach the purpose that a pump is used more with being connected of experimental setup.
The purpose of this utility model is achieved in that said vacuum pump suction port connection set is made up of a coupling sleeve and an above shunting nozzle, and an end of coupling sleeve is provided with the jackscrew of a plurality of radial arrangement, is used to block the minipump inlet tube.The other end integral body is connected with a square diffluence room, and a plurality of axially mutual vertically arranged tap holes are arranged in this diffluence room, and the shunting nozzle of a band valve is installed in each tap hole, is used for and the tight socket of the suction tude of experimental setup.Be provided with a funnel shape O-ring seal in coupling sleeve, this funnel shape O-ring seal can make the vacuum pump suction port and its tight connection of all size size.Jackscrew on the above-mentioned coupling sleeve can be 3 or 4, can establish 1～5 split-flow opening and shunting nozzle in the diffluence room.This connection set, except O-ring seal, all the other all can be made with materials such as metal and high strength plastics.
From as can be seen last, this connection set is applicable to being connected of various minipumps and experimental setup, use this connection set that the suction port of various minipumps and the air inlet nozzle of experimental setup closely and are stably linked together, and, owing to be provided with a plurality of shunting nozzles, can make a vacuum pump connect many experimental facilities as required.
Describe the utility model in detail below by embodiment and its accompanying drawing.
Fig. 1 is the front schematic view of the utility model connection set;
Fig. 2 is the A-A direction schematic representation among Fig. 1;
Fig. 3 is the B-B sectional view among Fig. 2.
Shown in above-mentioned figure, said connection set is made up of a coupling sleeve 1 and three shunting nozzles 4, and an end of coupling sleeve 1 is provided with the jackscrew 3 of three radial arrangement, to be used to block the minipump inlet tube.The other end integral body is connected with a square diffluence room 2, and three its axial mutual vertically arranged tap holes 6 are arranged in the diffluence room 2, and the shunting nozzle 4 of a band valve 7 is installed in each tap hole 6 threadably.In coupling sleeve 1, be provided with a funnel shape O-ring seal 5.
