Description

A kind of long-range N2O4Feed control device

Technical field

The utility model belongs to N₂O₄Fed technology field is related to a kind of long-range N₂O₄Feed control device.

Background technique

N2O4 is the toxic, strong oxidizer of one kind and strong corrosive.But current every profession and trade is all to take manual people in use Work feeding manner be easy to cause material leakage and personal injury accident in manual operation, since material corrosion is strong, just It is often used, overhauls, is more complicated, cumbersome in replacement process, needing to carry out professional training.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of long-range N₂O₄Feed control device reduces Field Force Directly contact the operation of N2O4 chance and Field Force.

In order to achieve the above objectives, the utility model provides the following technical solutions:

A kind of long-range N₂O₄Feed control device, including for connecting N₂O₄Storage tank and NO₂The Trunk Line of vaporizer, the master Pipeline is equipped with several material inlet valves, is set on the Trunk Line there are two pneumatic ball valve, the outlet of two pneumatic ball valves connects It further include being branched off from the Trunk Line to two material inlet valves, and and NO₂The branch line of vaporizer connection, institute Branch line is stated equipped with a reflux pipeline and N is connected to by the reflux pipeline₂O₄Storage tank.

Further, the NO₂The outer circumference surface of vaporizer, which is equipped with, is used for NO₂The collet of vaporizer heating.

The utility model has the beneficial effects that:

1. charging is quick, liquid is from storage tank into vaporizer, it is possible to reduce execute-in-place.

2. pneumatic ball valve good airproof performance, compact-sized, small and exquisite, it is not easy to leak.

3, prevent pipeline from blocking, so as to cause production parking etc..

Detailed description of the invention

In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows Attached drawing is illustrated:

Fig. 1 is the structural schematic diagram of this system.

Specific embodiment

Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.

As shown in Figure 1, a kind of long-range N₂O₄Feed control device, including for connecting N₂O₄Storage tank 1 and NO₂Vaporizer 2 Trunk Line 3, Trunk Line 3 are equipped with several material inlet valves 4, are set on Trunk Line 3 there are two pneumatic ball valve 5, two pneumatic ball valves 5 Outlet be connected at two material inlet valves, further include being branched off from Trunk Line 3, and and NO₂The branch that vaporizer 2 connects Pipeline 6, branch line 6 are equipped with a reflux pipeline 7 and are connected to N by the reflux pipeline 7₂O₄Storage tank 1.

In the present embodiment, NO₂The outer circumference surface of vaporizer 2, which is equipped with, is used for NO₂The collet 8 that vaporizer 2 heats.

In N₂O₄It feeds and pneumatic ball valve 5 is installed on Trunk Line 3, the outlet of pneumatic ball valve 5 is connected to two NO₂Vaporizer 2 into Expect at valve.By master control room according to NO₂The charging of 2 liquid level of vaporizer reduces Field Force and directly contacts N₂O₄Chance and Field Force Operation.By NO₂The former charging heating method of vaporizer 2 is changed to collet 8 by endless tube heating and heats, and heating effect is more preferably obvious.It will Branch line 6 is connect with reflux pipeline 7, forms annular return, it can be achieved that bidirectional feed and reflux.

Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details The range of restriction.
