Description
Technical Field
The utility model belongs to the technical field of coal mining equipment, concretely relates to rig negative pressure control box.
Background
The gas explosion has a certain concentration range, and the concentration range in which the gas in the air can cause explosion after encountering fire is called as a gas explosion limit. The gas explosion limit is 5% -16%. The gas overrun accident belongs to a relatively serious accident, and due to frequent occurrence of the gas overrun accident, the gas overrun accident can be prevented from being delayed, so that at present, when the gas abnormal accident occurs, negative pressure adjustment cannot be timely performed according to drilling abnormity, and the gas abnormal accident is caused and cannot be timely handled.
Disclosure of Invention
The utility model discloses to current rig punching process in, when appearing gas unusual, can not in time make the problem that the negative pressure adjustment was handled, provide a rig negative pressure control box.
The utility model adopts the following technical scheme:
the utility model provides a rig negative pressure control box, box including the rectangle, one side of box is equipped with through-hole I respectively along the length direction's of box both ends, be equipped with sleeve pipe I and sleeve pipe II on the through-hole I respectively, the one end of sleeve pipe I is equipped with the flange, be equipped with two through-holes II along box width direction between two through-holes I, be equipped with the sleeve pipe on the through-hole II respectively, sheathed tube one end is equipped with the ball valve respectively, the bottom of the box along the opposite side of direction of height is equipped with through-hole III, be equipped with the sleeve pipe on the through-hole III.
The axes of the sleeve I and the sleeve II are positioned on the same straight line.
And the axes of the two through holes II along the width direction of the box body are positioned on the same straight line.
The utility model has the advantages as follows:
through using the utility model discloses, when appearing gas unusual, only need operating personnel alone, three times negative pressure of control catch water that can be quick, accurate for when sending gas unusual, can fall to gas unusual accident to the minimum.

fig. 2 is a left side view structure diagram of the present invention;
FIG. 3 is a schematic top view of the present invention;
wherein: 1-a box body; 2-sleeve I; 3-sleeve II; 4-a flange; 5-sleeving a pipe; 6-ball valve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model provides a rig negative pressure control box, box 1 including the rectangle, one side of box 1 is equipped with through-hole I respectively along box 1's length direction's both ends, be equipped with sleeve pipe I2 and sleeve pipe II 3 on the through-hole I respectively, the one end of sleeve pipe I2 is equipped with flange 4, be equipped with two through-holes II along box 1 width direction between two through-holes I, be equipped with sleeve pipe 5 on the through-hole II respectively, the one end of sleeve pipe 5 is equipped with ball valve 6 respectively, box 1's bottom along direction of height's opposite side is equipped with through-hole III, be equipped with sleeve pipe 5 on the through-hole III, the one end of.
The axes of the sleeve I2 and the sleeve II 3 are positioned on the same straight line.
The axes of the two through holes II along the width direction of the box body 1 are positioned on the same straight line.
Wherein, the diameter of the sleeve I2 and the sleeve II 3 is phi 108, the flange 4 is a national standard flange of phi 108, and the ball valve 6 is a phi 40 ball valve.
The utility model discloses a use as follows:
4 inches of main negative pressure on a drilling site is connected to a three-inch and half-outlet of the box body of the utility model, and the other 4 inches of negative pressure outlet is connected to a 4-inch air inlet and outlet with steam-water separation by a 4-inch armored pipe, and a control valve is additionally arranged; two 2 inch outlet ends of the box body of the utility model are additionally provided with 40 ball valves, and are connected to two 2 inch inlet and outlet ends of a steam-water separator by using 2 inch armor pipes; the size of the valve is controlled by the captain.
By processing the device, a captain can quickly and accurately control the negative pressure of the steam-water separator for three times, so that when gas is abnormal, the abnormal accident of the gas can be reduced to the minimum.
