Abstract
The utility model discloses a pressure balance type gas injection digital valve. The pressure balance type gas injection digital valve comprises a valve body. The valve body is provided with an air inlet channel and an air outlet. A valve core is installed inside the valve body in a sliding mode. A moving armature is arranged at one end of the valve core, the valve body is provided with a static armature, and the static armature, an electromagnetic coil and the moving armature form an electromagnet. The direction of the tensile force exerted on the moving armature by the electromagnetism is the same as the sliding direction of the valve core. A reset spring is arranged between the valve body and the moving armature. The valve core is provided with a first valve and a second valve in the sliding direction of the valve core. The air inlet channel comprises a first air inlet and a second air inlet. When the digital valve is in the closed state, the first valve and the second valve are arranged between the first air inlet and the second air outlet, and the air outlet is arranged between the first valve and the second valve. The pressure balance type gas injection digital valve can achieve large-flow and fast-response injection under the condition of high pressure gas.
Description
Technical field
The utility model relates to the gas engine technical field, especially relates to a kind of pressure balance type gas and sprays digital valve.
Background technique
Emitted dose and response time are two important parameters weighing the gas spray valve quality, because the density of gas is lower, the latus rectum size of the valve that needs when injection flow is larger is also larger, but larger aero operating pressure acts on valve, can open and close motion to valve and produce inhibition, the restriction response time.Therefore, adopt the high speed electromagnetic gas spray valve of Electromagnetic Drive generally only can adapt to less traffic requirement and lower gas pressure condition, the high-speed quantitative that can't meet under larger flow and elevated pressures requirement is sprayed.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of pressure balance type gas to spray digital valve, can realize large flow, response injection fast under the pressurized gas condition.
the technical solution of the utility model is: pressure balance type gas sprays digital valve, comprise valve body, described valve body is provided with gas-entered passageway and air outlet, be slidably fitted with spool in described valve body, one end of described spool is provided with moving armature, described valve body is provided with static gag bit and electromagnetic coil and with described moving armature, forms electromagnet, moving armature is subjected to the electromagnet pull direction consistent with the spool glide direction, be provided with Returnning spring between described valve body and moving armature, described spool is provided with the first valve and the second valve along its glide direction, described gas-entered passageway comprises the first suction port and the second suction port, when described digital valve is in closed condition, described the first valve and the second valve are between described the first suction port and the second suction port, described air outlet is between described the first valve and the second valve.
As a kind of improvement, described valve body is provided be used to the controlling device of adjusting described Returnning spring pretightening force.
Preferably, described controlling device comprises be used to the regulator bolts of adjusting described Returnning spring pretightening force, and described regulator bolts is installed on described valve body and with described Returnning spring and leans mutually.
Adopted technique scheme, the beneficial effects of the utility model are: two valves are set on spool of the present utility model, make gas act on the pressure equal and opposite in direction of two valves, opposite direction, be close to zero the suffered gas pressure of spool with joint efforts, make spool still can keep fast response characteristic under large pressure and high flow capacity, this balance double-valve structure also has the large characteristics of gas injection flow simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Wherein: 1, valve body; 2, gas-entered passageway; 3, air outlet; 4, spool; 5, moving armature; 6, static gag bit; 7, electromagnetic coil; 8, Returnning spring; 9, the first valve; 10, the second valve; 11, the first suction port; 12, the second suction port; 13, regulator bolts.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
as shown in Figure 1, pressure balance type gas sprays digital valve, comprise valve body 1, valve body 1 is provided with gas-entered passageway 2 and air outlet 3, be slidably fitted with spool 4 in valve body 1, one end of spool 4 is provided with moving armature 5, valve body 1 is provided with static gag bit 6 and electromagnetic coil 7 and with moving armature 5, forms high-speed electro-magnet, moving armature 5 is subjected to the electromagnet pull direction consistent with spool 4 glide directions, be provided with Returnning spring 8 between valve body 1 and moving armature 5, spool 4 is provided with the first valve 9 and the second valve 10 along its glide direction, gas-entered passageway 2 comprises the first suction port 11 and the second suction port 12, when digital valve is in closed condition, the first valve 9 and the second valve 10 are between the first suction port 11 and the second suction port 12, air outlet 3 is between the first valve 9 and the second valve 10.
In addition, valve body 1 is provided with for the controlling device of adjusting Returnning spring 8 pretightening forces.
In the present embodiment, controlling device comprises that regulator bolts 13 is installed on valve body 1 and with Returnning spring 8 and leans mutually for the regulator bolts 13 of adjusting Returnning spring 8 pretightening forces.
Because the axially loaded area of the first valve 9 and the second valve 10 is equal, the first valve 9 and the second valve 10 are subject to gas load equal and opposite in direction, opposite direction, and making a concerted effort is zero.
When electromagnetic coil 7 dead electricity, under the resilient force of Returnning spring 8, the first valve 9 and the second valve 10 are pressed on valve body 1, form sealing, blocking-up gas from suction port to air outlet 3 circulation path, form closed condition.
When electromagnetic coil 7 electric generation electromagnetic force and overcome the elastic force of Returnning spring 8, can fast moving spool 4, the first valves 9 and the second valve 10 break away from sealing stations, suction port and air outlet 3 just are communicated with and form the gas injection.
Two the first valve 9 and the second valves 10 that area is close are set on spool 4, gas pressure acts on the power equal and opposite in direction of two valves, and opposite direction makes a concerted effort to be close to zero, therefore spool 4 has fast response characteristic under large pressure and high flow capacity, and irrelevant with the valve size.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
