According to the wire controller for the air conditioner,the connecting block is arranged on the outer wall of the pressing block; when a user presses the pressing block, the connecting rod can be driven by the connecting block to move, the user can drive the connecting rod more conveniently; a first spring is additionally arranged, so that when the user presses a clamping plate to the original position, the connecting rod can return to the original position, and the user can use the device more conveniently; and a sliding rod is additionally arranged, so that the stability of a sliding sleeve is improved, and when the clamping plate returns to the original position, the clamping plate does not move in the groove.

The invention relates to a soft sealing butterfly valve and a method for preparing a valve seat sealing ring thereof, wherein the valve body of the butterfly valve is provided internally with a valve seat; the valve seat is provided with a sealing ring for the soft sealing; the sealing side surface of the valve seat is provided with an annular groove the interior of which is large and the exterior of which is small; the sealing ring is fixed on the annular groove; the sealing surface of the top of the sealing ring is exposed outside the annular groove; and the part, positioned in the annular groove, of the sealing ring is matched with the groove wall of the annular groove. The method for preparing the sealing ring comprises: placing the main body of the sealing ring in the annular groove; pouring solidifiable resin in the annular center joint of the main body of the sealing ring through a through hole on the valve seat, and enabling two halves of the main body of the sealing ring to be expanded to cling to the side wall of the annular groove. According to the invention, the structure is simple, the sealing is reliable, and the sealing ring of the valve seat has less possibility of dropping and is suitable for various soft sealing butterfly valves.

A cab back cover is provided behind the cab of the vehicle and has an upper surface portion that prevents air flowing in from the front from flowing out upward, a rear surface portion that prevents air flowing in from the front from flowing out rearward, a left surface portion that prevents air flowing in from the front from flowing out leftward, and a right surface portion that prevents air flowing in from the front from flowing out rightward, wherein at least one of the left surface portion and the right surface portion has a front region extending inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle in a front-to-rear arrangement, and a rear region connected to the rear end of the front region and extending inward in the vehicle width direction of the vehicle at a second angle, which is larger than the first angle, in a front-to-rear arrangement.

The invention discloses high-efficiency chemical water-stemming which comprises an outer packaging film (1) and a liquid (2), wherein the liquid (2) is sealed in the outer packaging film (1); the liquid (2) comprises components in parts by weight as follows: 6-8 parts of a smoke eliminating agent, 6-9 parts of a flame eliminating agent, 5-7 parts of a foaming agent, 6-7 parts of a detergent, 7-9 parts of a dust depressor and 60-70 parts of water; the main component of the smoke eliminating agent is a mixture of sodium carbonate, sodium hydrogen carbonate, sodium phosphate and sodium silicate; the main component of the flame eliminating agent is a mixture of potassium sulphate, potassium nitrate, sodium chloride and potassium chloride; the main component(s) of the foaming agent are / is sodium nitrite and / or potassium nitrite; the main component of the detergent is sodium dodecyl benzene sulfonate; and the main component of the dust depressor is a mixture of water-soluble polymer, glycerol and calcium chloride. The high-efficiency chemical water-stemming has excellent effects of degrading and dissolving poisonous gases, eliminating smoke and flame, suppressing dust and blocking blasting holes; the cost is low; and the high-efficiency chemical water-stemming is widely applied to fields where the space of a roadway is small, the wind speed is low, and poisonous and hazardous gases are difficult to dilute.
