1942年5月，占领我华北地区的日军最高司令长官冈村宁次，为消灭我抗日根据地，对冀中平原实行惨绝人寰的？三光政策？，无数百姓遇害，许多抗日堡垒遭到破坏，抗日战争受到严重考验，为保卫我军总部和太行军工厂安全，冀中军区司令部决定用红色暴力打击敌人的白色恐怖。素有“鬼见愁”之称的抗日勇士康大光临危授命担任队长，并挑选了地雷专家小雷子，一刀砍死一个敌人的刘一刀，鬼子称为“小阎王”的阎铁柱及会说日语的汪子凤为队员，他们深入敌后首先直指那些出卖民族的叛徒……Since ancient times, every dynasty has a class solidified. However, no matter how the class solidifies, 5% of the poor can break through. Because they jumped out of the poor thinking caused by scarcity.时间似乎凝固了，这样的尴尬或者说特别的旖旎持续了好一会。I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.但是谁让陈启只是一个急等着用钱的新人作者。A low temperature stop valve, Unlike Example 1, Comprises a valve body 1 and a valve cover 2, A valve stem 3 is arrange in that valve body 1, One end of the valve stem 3 is provided with a valve disc 4, The other end of the valve stem 3 is provided with an adjusting handwheel 5, A low portion of that disc 4 is provided with a guide sleeve 6, The guide sleeve 6 is fixed by means of a connecting piece and a spring pad 8, Between that disc 4 and the guide sleeve 6 is provide a valve seat 7, Between that valve stem 3 and the valve cov 2 there is provided a packing assembly 9, An O-ring 10 is further dispose at that upper portion of the packing assembly 9, An upper part of that O-ring 10 is provide with a packing gland 11, The valve body 1 is provided with an arc-shaped end face 12, the arc-shaped end face 12 forms a line seal between the valve body 1 and the valve seat 7, the contact end of the valve disc 4 and the valve seat 7 is provided with a water grain surface 41, the packing assembly 9 comprises a flexible graphite packing layer, the valve body 1 is provided with a liquid inlet cavity and a liquid outlet cavity, the two O-rings 10 are concentric arranged, and the inner diameter and outer diameter of the two O-rings are different.
