The invention discloses a piston valve device which comprises an air inlet valve base, an air inlet valve and a fuel gas valve guiding pipe, wherein the bottom of the air inlet valve is sleeved and mounted in a cylinder cover guiding pipe hole; the fuel gas valve guiding pipe is sleeved on an air inlet part at the upper end of the air inlet valve; a thread taper pipe joint is arranged at an air inlet of the fuel gas valve guiding pipe; the thread taper pipe joint is in spiral connection with one end of a fuel gas pipe; and the other end of the fuel gas pipe is connected with a fuel gas linking hose through the thread taper pipe joint, an external sleeved nut and a gasket. A piston type fuel gas valve is reasonably applied by the invention; the gas suction/exhaust of the combustible gas is accurately controlled through the piston type motion of the fuel gas valve; the mixing of air and fuel gas in a cylinder of a fuel gas valve is finished; the blasting phenomenon is avoided; the energy resource is saved; the working efficiency is increased; and compared with the prior art, the piston valve device has the advantage that the safety is increased.
Description
Technical field
The present invention relates to a kind of gas machine equipment part, be specifically related to a kind of piston valve device.
Background technique
Diesel engine is in automobile making, very important status is had in the heavy industry such as steamer manufacture, but its power resources of diesel engine generally used on the market are at present mainly based on burning diesel oil, and the price of diesel oil day by day increases, and burning diesel oil also can cause serious pollution, even if there is portion gas machine to be improved to the mixed gas of combustion air and combustion gas to obtain power, but current technology, air and combustion gas can only realize mixing outward at the cylinder of gas machine, pass into again in firing chamber after mixing, ignition, this mode easily produces blows out phenomenon, and mixed gas burning is not thorough.
Summary of the invention
Goal of the invention: the object of the invention is, in order to solve the deficiencies in the prior art, to provide a kind of piston valve device.
Technological scheme: a kind of piston valve device, described piston valve device comprises suction valve cone, the intake valve be arranged on suction valve cone is socketed from the bottom to top with 70 degree-an angle of 90 degrees degree, be socketed the combustion valve guide bushing be arranged on intake valve, spiral is fixedly mounted on the thread conical pipe joint on the suction port of combustion valve guide bushing, be socketed in the piston type fuel gas door in combustion valve guide bushing, screw-casing is connected on the fuel tube on thread conical pipe joint, spiral is arranged on the screwed pipe joint in fuel tube, combustion gas hose is socketed on screwed pipe joint, socket place is fixed by cap nut, pad is arranged on screwed pipe joint.
As preferably, be provided with seal ring and seal ring in described combustion valve guide bushing, the number of described seal ring is 3.
As preferably, described combustion valve guide bushing is provided with suction port and air outlet, and air outlet bore is less than suction port.
The suction valve cone of piston valve device of the present invention is processed by imported materials, this material has hard, flexible, wear-resisting, heatproof, the advantage such as corrosion-resistant, the impact of more resistance to hot environment simultaneously, do not split indeformable, wear extent is few, intake valve is processed by figure by special material, the structure of intake valve is different from conventional valve, it opens and closes combustion gas limit along with the to-and-fro motion of self, the same with the working principle of valve seat with valve, open and close are controlled by the cam rocker arm mechanism on its top, because combustion gas has certain pressure, it is Spielpassung between valve and guide pin bushing, a small amount of combustion gas and air must be had in air inlet tube chamber to mix, but combustion gas can not channel in cylinder upper part of the cover rocker arm chamber, inflammable gas is caused naturally to run off, loss energy, inflammable gas flees hither and thither on the other hand, very dangerous, because this gas runs into naked light and will burn, even explode, therefore install abrasive rubber seal ring additional in its valve stem and seal, due to intake valve material by special material precision manufactureing out, built-up welding cobalt base alloy on its valve face, play corrosion resistance, wear-resisting, impact-resistant effect, combustion valve guide is processed by special process, it is all very accurate and ingenious that its machining accuracy and dimensional chain coordinate, it also has special requirement when installing, lubricant oil is immersed in after process finishing, anti-friction agent is with the addition of in lubricant oil, make lubricant oil deep penetrate in the fine pore of spheroidal graphite cast iron, play wear-resisting effect.
Beneficial effect: a kind of piston valve device of the present invention, reasonable utilization piston type fuel gas door, by the piston like motion of combustion gas door, control the intake and exhaust of inflammable gas accurately, complete air and combustion gas mixes in the cylinder of diesel engine, avoid and blow out phenomenon, saved the energy, improve the Security of working efficiency and work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view firing valve guide bushing in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail.
As Fig. 1, shown in Fig. 2, a kind of piston valve device, comprise suction valve cone 1, the intake valve 2 be arranged on suction valve cone 1 is socketed from the bottom to top with 70 degree-an angle of 90 degrees degree, be socketed the combustion valve guide bushing 3 be arranged on intake valve 2, spiral is fixedly mounted on the thread conical pipe joint 4 on the suction port 13 of combustion valve guide bushing 3, be socketed in the piston type fuel gas door 5 in combustion valve guide bushing 3, screw-casing is connected on the fuel tube 7 on thread conical pipe joint 4, spiral is arranged on the screwed pipe joint 8 in fuel tube 7, combustion gas hose 11 is socketed on screwed pipe joint 8, socket place is fixed by cap nut 10, pad 9 is arranged on screwed pipe joint 8, in combustion valve guide bushing 3, seal ring 6 and seal ring 14 are installed.
After piston type fuel gas door 5 makes it dock with fuel tube 7 by piston movement in combustion valve guide bushing 3, inflammable gas just enters in combustion valve guide bushing 3 by fuel tube 7, and finally enter in gas machine cylinder by the air outlet 12 of combustion valve guide bushing 3, by spark ignitor after mixing in cylinder with the air entered in cylinder, thus gas machine is made to obtain power.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
