A coal mine negative pressure automatic water tank, including a box body, the box body is iron hollow cylinder, the top of the box is iron cover plate, the box is fixed with screw and ring rubber pad, there are inlet pipe mouth and pressure relief hole on the cover board, the pressure relief hole is controlled by the glial ball, and there are two living cylinder floating balls inside the box, from the polymer polyethylene. The bottom of the box body is two fixed pulleys, which are used for fixing the direction of the connecting rope, and one side of the box body is a water outlet pipe. When the water comes in from the inlet of the inlet, as the water level rises, the floating ball on the left is pulled into the water gradually because the buoyancy is larger than the right, and the floating ball on the right side is gradually pulled into the water, and the floating ball on the left is gradually raised and the pressure of the pressure reducing glial ball is opened. The pressure in the box is balanced with the outside, and the floating ball of the outlet begins to float, when the water level drops. After that, the floating ball on the left side is no longer in the water. The buoyancy on the right side of the floating ball is gradually greater than the sum of the left buoyancy and the negative pressure of the inlet. Finally, the floating ball on the left side is pulled down, the box is in the negative pressure again. The floating ball of the outlet pipe is blocked by the negative pressure to plug the outlet, and the inlet of the inlet begins to enter the water, and the water is circulated in turn.

一种煤矿用负压自动放水箱
本技术涉及一种煤矿用负压自动放水箱。
技术介绍
负压瓦斯抽采管道放水是煤矿瓦斯抽采工作的重要环节,负压自动放水需要平衡放水箱内外压力,现有的负压自动放水箱内部为铁质中空单浮球,由中间一根控制杆固定方向,负压平衡依靠几根胶质小管及两个小浮球联动工作。这样的技术存在以下不足:内部构造较为复杂,在管道压力超过20kp的情况下很容易出现故障,影响瓦斯正常抽采,且维修难度较大,复用率较低。
技术实现思路
本技术的目的在于提供一种煤矿用负压自动放水箱,可以使瓦斯抽采管道稳定放水,维修简单,可重复使用,以弥补现有技术的不足。本技术的目的是这样实现的:一种煤矿用负压自动放水箱,包括箱体,箱体为铁质空心圆柱体,箱体顶部为铁质盖板,由螺丝及环形胶垫进行固定,盖板上有进水管口及减压孔,减压孔由胶质球进行控制,箱体内部有两个活动圆柱体浮球,由高分子聚乙烯绳连接,箱体内底部为两个定滑轮,用于固定连接绳方向,箱体一侧为放水管孔,出水管口有浮球控制。通过实施本技术,可以使瓦斯抽采管道稳定放水,减少了水对瓦斯抽采的影响,保证了瓦斯抽采的可靠性。以下结合附图通过实施例对本技术 ...
