Description

Four-way valve for hydrogen crushing furnace

Technical Field

The utility model belongs to the technical field of machinery, concretely relates to cross valve for hydrogen garrulous stove.

Background

The hydrogen crushing furnace is used for forming ingot-shaped or sheet-shaped rare earth alloy materials into powder through non-mechanical force. The hydrogen reacts with the rare earth alloy (such as Nd2Fe14B) to produce crystal fracture and transgranular fracture in the hydrogen absorption and desorption process of the rare earth alloy (such as Nd-Fe-B alloy) to cause the rare earth alloy to be pulverized to form an embrittlement and crushing process, thereby obtaining the rare earth alloy powder with a certain particle size. After the rare earth alloy is put into a reaction kettle in a hydrogen crushing furnace, air in the reaction kettle needs to be firstly pumped out to form vacuum, and then hydrogen is filled into the reaction kettle, although a filter cartridge is installed on a four-way valve of the conventional hydrogen crushing furnace, the filter cartridge is directly fixed in the four-way valve, when the filter cartridge needs to be replaced or cleaned, the whole four-way valve needs to be detached from the hydrogen crushing furnace, and after the filter cartridge is cleaned or replaced, the whole four-way valve needs to be reinstalled on the hydrogen crushing furnace, so that the time and labor are wasted, and the efficiency is low.

Disclosure of Invention

The utility model aims at solving the problems in the prior art and providing a four-way valve for a hydrogen furnace, which has simple structure, is practical and convenient.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a cross valve for hydrogen crushing stove, the cross valve is by the last valve body that top-down set gradually, well valve body and lower valve body are constituteed, the air inlet has been seted up at last valve body top, the feed inlet of valve body in transversely lining up is seted up to well valve body in well valve body, the feed back mouth has been seted up to the valve body lower extreme under, a serial communication port, lateral part at last valve body seted up with the communicating square installing port of last valve body inner chamber, it has the ring flange to have through the bolt seal closing cap in square installing port department, the mount pad has been equipped with in last valve body, set up the passageway that link up last valve body and well valve body on the mount pad, there is cylindric cartridge filter through the clamp connection on the mount pad, the cartridge filter is just less than the length and the width of square installing port and cartridge filter, the cladding has the filter screen on the filter cartridge outer wall.

In foretell a cross valve for hydrogen garrulous stove, the section of thick bamboo wall of cartridge filter is gone up and is surrounded the through-hole that is equipped with a plurality of evenly distributed, and the filter screen passes through the clamp to be fixed on the filter cylinder outer wall.

Compared with the prior art, the utility model discloses a set up the mount pad in last valve body, pass through the clamp with the cartridge filter and install on the mount pad, make and form detachable construction between cartridge filter and the mount pad, seted up simultaneously at the lateral part of last valve body with the communicating square installing port of last valve body inner chamber, the cartridge filter is just all less than the length and the width of square installing port to the length and the width of square installing port and cartridge filter, this makes and smoothly takes out the cartridge filter from last valve body through square installing port, thereby when needing to change the cartridge filter, only need to plug up the ring flange dismantlement of square installing port department, can take out the cartridge filter from last valve body, thereby need not take off whole cross valve from the hydrogen garrulous stove, convenient change and maintenance.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figure 1, the four-way valve for the hydrogen crushing furnace consists of an upper valve body 1, a middle valve body 2 and a lower valve body 3 which are sequentially arranged from top to bottom, the top of the upper valve body 1 is provided with an air inlet 11, the middle valve body 2 is provided with a feed inlet 21 which transversely penetrates through the middle valve body 2, a feed back port 31 is arranged at the lower end of the lower valve body 3, a square mounting port 12 communicated with the inner cavity of the upper valve body 1 is arranged at the side part of the upper valve body 1, a flange plate 4 is sealed and covered at the square mounting port 12 through a bolt, a mounting seat 5 is arranged in the upper valve body 1, a channel 51 which penetrates through the upper valve body 1 and the middle valve body 2 is arranged on the mounting seat 5, be connected with through clamp 6 on mount pad 5 and be cylindric cartridge filter 7, cartridge filter 7 just all is less than the length and the width of square installing port 12 to the length and the width of square installing port 12 and cartridge filter 7, and the cladding has filter screen 8 on 7 outer walls of cartridge filter.

An air inlet 11 at the top of the upper valve body 1 is communicated with an external pipeline, so that air in the reaction kettle can be pumped out to form vacuum, and hydrogen is filled into the reaction kettle through the air inlet 11. Through setting up mount pad 5 in last valve body 1, install cartridge filter 7 on mount pad 5 through clamp 6, make and form detachable construction between cartridge filter 7 and the mount pad 5, set up the square installing port 12 communicating with last valve body 1 inner chamber simultaneously at the lateral part of last valve body 1, cartridge filter 7 is just being less than the length and the width of square installing port 12 to square installing port 12 and cartridge filter 7, this makes can smoothly take out cartridge filter 7 from last valve body 1 through square installing port 12, thereby when needing to change cartridge filter 7, only need to plug up the ring flange 4 of square installing port 12 department and dismantle, can take out cartridge filter 7 from last valve body 1, thereby need not take off whole cross valve from the hydrogen crushing stove, convenient change and maintenance.

The wall of the filter cartridge 7 is surrounded by a plurality of uniformly distributed through holes 71, and the filter screen 8 is fixed on the outer wall of the filter cartridge 7 through the hoop 6, the through holes 71 can ensure that the air in the reaction kettle can smoothly pass through the filter cartridge 7 and be discharged from the air inlet 11, and simultaneously can ensure that the hydrogen can smoothly enter the reaction kettle through the through holes 71, and in the process of vacuumizing, a part of rare earth particles in the reaction kettle can enter the filter cartridge 7 along with the air, the rare earth particles are adsorbed by the filter screen 8, so that the rare earth particles are ensured not to be discharged, and in the process of filling the hydrogen, the hydrogen gas flow adsorbed on the rare earth particles in the filter screen 8 is impacted and then returns to the reaction kettle again.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
