Abstract
The utility model relates to the preventing clogging up device of air-entrained concrete building block production process middle steam tube, more particularly to a kind of anti-blocking plug valve of steam, it include: valve rod, valve body, limited block, graphite packing, seal joint, cylinder, a kind of anti-blocking plug valve of steam of the utility model, the utility model reality valve is the direct sealing orifice of the conical surface for using the valve stem end lengthened, and steam passes through around valve rod.Valve rod is opened and closed with cylinder, cylinder solenoid valve control.Cause slurry to flow into valve to open by mistake valve when preventing no steam or low steam pressure, adds a pressure switch in the front end of valve, pressure is not powered lower than setting pressure, solenoid valve, and valve will not be opened, it is ensured that whenever slurry can not all flow into valve.
Description
Technical field
The utility model relates to air-entrained concrete building block production field more particularly to a kind of anti-blocking plug valves of steam.
Background technique
Air-entrained concrete building block is that a kind of light porous, insulation, fire protecting performance be good, nailable, sawable, planable and tool
There are the New Building Materials of certain shock resistance, in the production process of aerated-block brick, needs in casting blender with steaming
Vapour is inserted into slurry steam direct heating, and heating is adjusted according to process requirement, and when stopping heating, air expands with heat and contract with cold
It is easy to suck in slurry, steam pipe is solidified and blocks and causes to be unable to normal use.
Utility model content
The purpose of the utility model is to provide one kind to prevent slurry from blocking, and can open at any time, what stagnation was closed when not used
Valve solidifies to guarantee that steam nozzle will not ooze into slurry.
A kind of anti-blocking plug valve of steam, characterized by comprising: valve rod and valve body, the body top are provided with sealing pressure
Ring, the valve stem top are provided with the block with valve-stem integrated structure, fill out between the seal joint and block filled with graphite
Material, the valve stem top are connected with cylinder, and flexible limited block is arranged in the bottom of the valve rod.
Preferably, the quantity of the limited block is four, symmetrical as axle center using the central axis of valve rod.
The utility model has the advantages that a kind of anti-blocking plug valve of steam of the utility model, easy to operate, slurries can be effectively avoided to stop
Suck-back enters steam nozzle when only steam is discharged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: valve rod 1, valve body 2, limited block 3, graphite packing 4, seal joint 5, cylinder 6.
Specific embodiment
The utility model is described further below in conjunction with attached drawing:
Embodiment:
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of steam is anti-
Blocking valve, comprising: valve rod 1, valve body 2, limited block 3, graphite packing 4, seal joint 5, cylinder 6.
The body top is provided with seal joint, and the valve stem top is provided with the block with valve-stem integrated structure, institute
It states filled with graphite packing between seal joint and block, the valve stem top is connected with cylinder, the bottom setting of the valve rod
Flexible limited block.
The quantity of the limited block is four, symmetrical as axle center using the central axis of valve rod.
As shown in Figure 1, opens solenoid valve band ovable valve stem increases when steam pipe needs to be discharged steam, gas outlet ventilation, when need
Stop closing solenoid valve when ventilation, valve rod is resetted by gravity closes gas outlet.
The utility model reality valve is the direct sealing orifice of the conical surface for using the valve stem end lengthened, and steam passes through around valve rod.Valve
Bar is opened and closed with cylinder, cylinder solenoid valve control.Cause to expect to open by mistake valve when preventing no steam or low steam pressure
Slurry flows into valve, adds a pressure switch in the front end of valve, pressure is not powered lower than setting pressure, solenoid valve, and valve will not
It opens, it is ensured that whenever slurry can not all flow into valve.
Using technical solution described in the utility model or those skilled in the art in technical solutions of the utility model
Under inspiration, similar technical solution is designed, and reaches above-mentioned technical effect, is the protection model for falling into the utility model
It encloses.
