Background
At present, reciprocating diaphragm compressors at home and abroad are mainly applied to the field of new energy sources such as automobile hydrogen stations and the like, because a compression medium is hydrogen, steel which is very easy to contact with the hydrogen is polymerized into hydrogen molecules under a high-temperature and high-pressure state, so that local stress of the steel is concentrated, fine cracks are formed in the steel, and once the cracks are accumulated and increased, the material is embrittled or even cracked (hydrogen embrittlement phenomenon for short), so that a great potential safety hazard is caused to equipment.
As shown in fig. 1 (a) and 1 (b), the diaphragm head at the gas side of the diaphragm compressor mainly comprises a diaphragm head body 1 and a diaphragm disk body 2 connected with the diaphragm head body 1, wherein a gas inlet valve hole 3 and a gas outlet valve hole 4 are arranged in the diaphragm disk body 2, and a gas inlet valve and a gas outlet valve are respectively arranged in the gas inlet valve hole and the gas outlet valve hole. Because the structure is complex and various functional holes are arranged in the diaphragm compressor, the gas side diaphragm head of the existing diaphragm compressor is usually cooled by directly arranging a water inlet channel 5 and a water outlet channel 6 on the upper side and the lower side of a diaphragm head body 1 respectively, then arranging a diamond-hole-shaped intercommunicated cooling water channel between the water inlet channel and the water outlet channel, and introducing cooling water into the diaphragm head body in a mode of feeding cooling water from bottom to top so as to cool the diaphragm head body and compressed hydrogen.

2. The membrane disk body does not design cooling structure, and the potential safety hazard is great.
Compared with the membrane head body 2, the membrane disk body 2 has a larger area in direct contact with compressed hydrogen, the cooling structure of the traditional gas side membrane head part is designed on the membrane head body, and the membrane disk body is not designed with the cooling structure, so that the membrane disk body has a higher probability of hydrogen embrittlement with hydrogen in a high-temperature and high-pressure state, and has larger potential safety hazard.

The water inlet channel 5 is communicated with a three-dimensional cooling water channel 7 arranged in the membrane disc body 2. When the diaphragm compressor works, a piston (not marked in the figure) in the cylinder body 12 acts on the diaphragm 11, gas to be compressed enters a compression space formed by the diaphragm 11 from the pressure valve rod 8 through the air inlet valve 3 to be compressed and is exhausted through the exhaust valve 4, in the process, the right end face of the diaphragm disc body 2 and the position area of the exhaust valve generate high temperature, cooling water flows in from the water inlet channel 5 and flows out from the water outlet channel 6 after passing through the three-dimensional cooling water channel 7 to participate in an external cooling system to form circulation so as to cool the diaphragm disc body 2.
As shown in fig. 3 and 4, the stereoscopic cooling channel 7 includes a set of a first channel 710, a second channel 720, a third channel 730, and a fourth channel 740. The first water channel 710 and the fourth water channel 740 are disposed at the junction of the membrane head body 1 and the membrane disc body 2, wherein the first water channels 710 are circumferentially spaced apart and are located near the outer side of the junction of the membrane head body 1 and the membrane disc body 2.

In addition, the sealing structure may also adopt other forms, such as a sealing gasket + a high temperature resistant sealant coating manner to improve the sealing performance, and the sealing gasket may be correspondingly arranged according to the shape of the arc-shaped short grooves 711.
Both ends of the first water channel and the fourth water channel in the length direction are communicated with a second water channel 720 which is arranged along the axial direction of the membrane disc body 2. In consideration of the convenience of processing, the second water passage 720 is a blind hole perpendicular to the end face of the membrane disc 2, and the diameter of the blind hole is the same as the width of the arc-shaped short groove 711.
The third water channel 730 is arranged in the cross section of the membrane disc body 2 and close to the right end face of the membrane disc body 2. The third water passage 730 is a linear pipe formed by drilling a hole on the peripheral side surface of the membrane disk 2 and sealing and blocking the orifice. Each third water channel 730 is correspondingly communicated with the second water channels 720 correspondingly communicated with the first water channel and the fourth water channel one by one, so that each first water channel, each second water channel, each third water channel and each fourth water channel are connected in series to form a three-dimensional cooling water channel 7 which is zigzag and closed in the transverse and longitudinal directions.
In order to guarantee that the cooling water is completely full of the three-dimensional cooling water channel 7 and discharges the air in the water channel, the heat exchange is fully carried out, the water gap of the water inlet channel 5 is positioned at the right lower side of the membrane head body 1, and the water gap of the water inlet channel 5 is positioned at the right upper side of the membrane head body 1.

As shown in fig. 5, the cooling water flows into the first water passage 710 on the lower side from the water inlet passage 5, and branches are formed by branching from both ends of the arc-shaped short groove 711 of the first water passage 710. Each branch comprises a group of first to fourth water channels which are sequentially communicated in series, and cooling water finally converges in the first water channel 710 at the upper side after passing through the two branches and flows out through the water outlet channel 6.
Compared with fig. 1 and 5, the prior art of fig. 1 only cools a small part of the area close to the air inlet and outlet holes in the membrane head body, and the cooling effect is very limited due to the short length of the cooling channel. The invention cools the membrane disc body, is provided with the three-dimensional cooling water channel which is zigzag and closed in the transverse and longitudinal directions and covers most of the area in the membrane disc body, thereby better achieving the purposes of taking away the heat in the membrane disc body and cooling the high-pressure hydrogen. In addition, a fourth water channel with a small gap is arranged in the area close to the exhaust valve, and the corresponding second water channel is arranged densely, so that the cooling effect of the exhaust valve area is improved. Through estimation, the length of the cooling channel of the film disc body is more than 3 times of that of the cooling channel in the figure 1, and under the condition that the sectional areas of the cooling channel and the film disc body are close, the internal heat exchange area of the film head is more than 3 times of that in the figure 1, which also means that the cooling effect is greatly improved.
The invention reduces the temperature of the gas pressure side and the exhaust seat hole area of the membrane disc body by cooling the membrane disc body, reduces the hydrogen embrittlement phenomenon generated by steel materials contacted with hydrogen under the conditions of high temperature and high pressure, eliminates the potential safety hazard and prolongs the service life of the membrane head.
