Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fire-fighting valve to solve the problem that the operation efficiency of the fire-fighting ball valve is often tested by cross-communication transportation to test the effect of pipe butt joint operation, but this will cause the cross-pipe diversion flow to be different. As a result, the distribution of the three-pronged pipeline will also cause overflow at the knuckle end and insufficient water pressure to reduce the flow rate. The pump pressure on the internal structure of the conventional ball valve is often only the impact force of the axis, which will cause the subsequent ball valve linkage. The existing pressure drops sharply, and the problem of continuous consumption of valve dredging power and flow

Embodiment 1

[0035] see Figure 1-Figure 8 , the present invention provides a fire valve, the structure of which includes: hoop sleeve plate seat 1, drain pipe end groove 2, star shot propeller ball valve 3, handle wheel frame 4, pressure flow support 5, nut base block 6 , the star-shooting propeller ball valve 3 is nested under the bottom of the pressure flow support 5 and the axes are collinear, the hoop sleeve disc seat 1 is fastened together with the drain pipe end groove 2 and communicates with each other, the The end groove 2 of the drain pipe is inserted on the right side of the star-shooting propeller ball valve 3 and the axes are co-linear, the handle frame 4 is inserted on the top of the pressure flow support 5, and the nut base block 6 Set under the bottom of the star-shooting propeller ball valve 3 and the axes are collinear. The star-shooting propeller ball valve 3 is provided with a shock-absorbing support rod 3A, a star-shooting nozzle frame 3B, an outer ball valve housing 3...

Embodiment 2

[0043] see Figure 1-Figure 8 , the present invention provides a kind of fire valve, other respects are identical with embodiment 1, and difference is:

[0044] see image 3 , the pressure flow support 5 is made up of a bead groove plate 51 and a plate pressure cylinder seat 52, the bead groove plate 51 is installed inside the plate pressure cylinder seat 52, and the bead groove plate 51 and the plate pressure cylinder seat 52 adopt Interference fit, through the bead groove plate 51 in the plate pressure cylinder seat 52 to fit the ball valve housing horizontally and vertically to carry out press fitting and fastening, so as to improve the overall locking density.

[0045] see Image 6 The bead groove plate 51 is composed of a damping tube 511, a frame groove pad 512, and a flat plate groove 513. The damping tube 511 is embedded in the frame groove pad 512 and is on the same vertical plane. The frame groove pad 512 is provided with two and respectively nested in the left an...

Abstract

The invention discloses a fire valve which structurally comprises a hoop sleeve disc base, a water drainage pipe end groove, a star-jet propeller ball valve, a handle wheel carrier, a pressure flow support seat and a nut base block. According to the fire valve, through cooperation of the water drainage pipe end groove and the star-jet propeller ball valve, a short pipeline groove and an outer ball valve shell cooperate with a damping bracket rod and spiral flow guide stamping in a star-jet nozzle frame to improve the flow dividing efficiency and the continuously-supplied pressure impulse, the continuity and stability of the whole pipeline butt joint flow are guaranteed, and the phenomenon that improvement is insufficient due to too large water pressure is avoided; and repeated acting force of spiral stamping of the star-jet nozzle frame and the extraction operation effect of a water wheel type damping bracket rod framework are guaranteed, a fire ball valve is in butt joint with a fire-fighting truck for water supply and supplementing, the fire-fighting projection radian output by a pipeline is high, and the effect of converging and pressurizing a small-flow converging opening is achieved at the water source end.

Description

technical field [0001] The invention is a fire-fighting valve, which belongs to the field of valves. Background technique [0002] The fire valve is a valve body that is connected to the water supply of the fire truck and the fire water pipe for sprinkler irrigation and fire extinguishing operations. The valve has the effect of docking the pipeline and calling the water flow for a short period of continuous supply to cooperate with the fire extinguishing operation, and improves the efficiency of the fire fighting operation to facilitate quick connection and water supply for the fire truck. Operation, the disadvantages of the current technology to be optimized are: [0003] The operation efficiency of the fire ball valve is often tested by the cross-connection transmission to test the operation effect of the pipe connection, but this will cause the flow of the cross-pipe diversion to be different, so that the distribution of the three-prong pipe will also cause overflow at th...
