The invention discloses a flat gate valve with a fire resistant function. The flat gate valve comprises a valve body, a valve deck and a top cover. The valve body, the valve deck and the top cover are sequentially arranged from bottom to top. The valve body and the valve deck are fixed through a bolt. The top cover and the valve deck are fixed through a bolt. A valve seat is mounted in the valve body. A valve plate is mounted in the valve seat. The valve plate and the valve seat are clamped. A valve rod is fixed to the top of the valve plate. A containing cavity is formed in the bottom of the valve body and sequentially penetrates through the valve deck and the top cover. The gap between the top of the valve deck and the valve rod is filled with packing. Sealing grease is injected into the packing. A valve rod nut is mounted at the top of the valve rod. A hand wheel is fixed to the outer side of the valve rod nut. A flashboard of the flat gate valve with the fire resistant function has the high temperature resistant effect, the fire resistant effect is good, and sealing can be maintained as long as 12 minutes in the hydraulic pressure sealing experiment state.

The invention relates to the technical field of gas pipeline fire prevention, in particular to a pipeline coating and a preparation method thereof. The pipeline coating is prepared from MOFs, vermiculite, an organic solvent and a bonding agent. The preparation method of the pipeline coating comprises the steps of dissolving the MOFs powder in the organic solvent to obtain a settled solution; adding vermiculite powder into the settled solution to obtain suspension liquid; adding the bonding agent into the suspension liquid and conducting spray granulation to obtain powder; spraying the powder onto the surface of a pipeline through a plasma spraying method to form the pipeline coating. The connection strength of the coating and metal is reinforced through powerful chemical bonds formed between the MOFs and the metal, and the phenomenon of powder stripping of the coating is avoided. As the MOFs is formed by arranging long-rage ordered crystal grains in microstructure, the pipeline coatinghas the good compactness, and the problem of cracking of the coating is solved. Meanwhile, through combination with the vermiculite, the pipeline coating can release crystal water contained in vermiculite layers when heated, thereby achieving the fire prevention effect.

A heat-sensitive fireproof and thermal insulation wall, which belongs to the technical field of energy-saving buildings, is provided with a thermal insulation cavity in the center of the reinforced concrete wall, and a thermal insulation layer made of inorganic water-absorbable thermal insulation cotton is arranged in the cavity. The top of the insulation layer is provided with a water storage tank and a spray pipe, the spray pipe is controlled by a micro-power switch and a temperature controller, and is connected to a thermal sensor; The sensitive sensor, the micro-power switch and the temperature controller are electrically connected to the storage battery respectively; the inorganic porous fiber cotton rainwater storage and release module is used as the inorganic water-absorbable thermal insulation cotton; the beneficial effect is that the thermal insulation layer is made of inorganic water-absorbable thermal insulation cotton. When a fire occurs, the spray pipe will spray water on the inorganic absorbable thermal insulation cotton, because the inorganic absorbable thermal insulation cotton can absorb water and retain water, forming a water wall layer, which can effectively prevent the fire from spreading; the thermoelectric generation layer can effectively use indoor and outdoor heat energy, and provide power for a long time .

The invention relates to a fireproof cable bridge which comprises a cover plate, two C-shaped side plates with corresponding openings, a first phenol resin plate, two second phenol resin plates and a third phenol resin plate, wherein the first phenol resin plate is transversely paved on the upper end surfaces of installation portions of the C-shaped side plates, and a base plate is arranged on the upper end surface of the first phenol resin plate. A protrusion portion is arranged on the upper end surface of a supporting portion of each C-shaped side plate, a corresponding groove is arranged on the lower end surface of each supporting portion at the position corresponding to the protrusion portion, the cross sections at the upper ends of the second phenol resin plates in the longitudinal direction are matched with the grooves, and the lower end surfaces of the second phenol resin plates butt against the upper end surface of the base plate. Steps are formed between corresponding lateral sides on the supporting portions of the two C-shaped side plates and respective protrusion portions respectively, and two sides of the third phenol resin plate are in lap joint with the steps respectively. The fireproof cable bridge has a fireproof effect due to the fact that the phenol resin plates have good heat isolation and fireproof performances.

The invention relates to fire-retardant water-based dual-component top-coat paint for wood ware and a preparation method of the paint. The fire-retardant water-based dual-component top-coat paint for the wood ware consists of a component A and a component B, wherein the ratio of the component A to the component B is 100 to 20. The preparation method of the fire-retardant water-based dual-component top-coat paint for the wood ware comprises the following steps: a. preparing the component A as the follows; b, preparing the component B from Bayer XP2487-1; and c. before construction, uniformly stirring the component A and the component B fully in a weight ratio of 100 to 20. The fire-retardant water-based dual-component top-coat paint for the wood ware can be used for achieving a fire-retardant effect under the circumstance of not adding a fire retardant; the paint coating the wood ware and metal can be used for avoiding ignition in burning, bubbling, scorching, peeling off and pulverizing. The fire-retardant water-based dual-component top-coat paint for the wood ware has the effects of alcohol resistance, acid and alkali resistance, yellowing resistance, high hardness, stain resistance, and the like.
