Abstract
The utility model relates to an automatic air control switching valve particularly for a train locomotive. The utility model comprises a valve body, an air inlet channel, a main air outlet channel connected with a filter device, an auxiliary air outlet channel communicated with the air inlet channel and a switching valve core for sealing the main air outlet channel or the auxiliary air outlet channel, wherein, the switching valve core is arranged in a sliding mode in a sliding groove in the valve body. One end of the switching valve core is exposed to the air inlet channel and the other end of the switching valve core is exposed to a high pressure air cavity. The high pressure air cavity for pushing the switching valve core is connected with one controlled high pressure air source. A seal element is arranged between the switching valve core and the sliding groove. Seal elements are also arranged in sealing positions between the switching valve core, the main air outlet channel and the auxiliary air outlet channel. Under the condition that an air source dryer of the train locomotive can not be normally operated, air can be switched to be directly transmitted to an air cylinder by the utility model. If the air source dryer is recovered to operate normally, the switching valve core can be automatically returned. The utility model utilizes the air to automatically return, has no rust and no aging and has the advantage of long utilization time.
Description
One, technical field
The utility model relates to a kind of automatic wind control switching valve, particularly a kind of automatic wind control switching valve that is used for engine.
Two, background technique
Present train internal combustion, electric locomotive adopt air damping to stop substantially, and required air flows into reservoir again after the wind regime exsiccator filters.And existing wind regime exsiccator does not have protective system, and reservoir does not have standby defeated wind system yet, if the wind regime exsiccator can't proper functioning, reservoir then can't obtain replenish air, and air pressure can descend, and serious meeting causes train to brake.Produce for like this transportation and bring very big danger.
Three, summary of the invention
The utility model to solve engine wind regime exsiccator can't proper functioning the problem that can't brake of train then, the automatic wind control of a kind of two-position three way switching valve is provided, two air outlet channel connects wind regime exsiccator and reservoir respectively, under the wind regime exsiccator can't the situation of proper functioning, air can directly flow to reservoir.
Automatic wind control switching valve described in the utility model comprises valve body, intake duct and is connected with the main air outlet channel of filtrating equipment, also has on the valve body: the auxilliary air outlet channel that is communicated with intake duct; Can seal the switching spool of main air outlet channel or auxilliary air outlet channel; Switch spool and be slidably mounted in the interior sliding-groove of valve body, an end that switches spool is exposed to intake duct, and the other end is exposed to the high pressure air cavity; Be used to promote to switch the high pressure air cavity of spool, described high pressure air cavity connects a controlled high-pressure air source; Between described switching spool and the described sliding-groove Sealing is housed, Sealing also is equipped with in sealing place of described switching spool and main air outlet channel and auxilliary air outlet channel.
The switching spool is positioned between auxilliary air outlet channel end and sliding-groove and is lined with valve pocket.
Be equipped with on the intake duct and switch the valve seat that spool matches.
The utility model has the advantages that:
Automatically wind control switching valve can switch to air and directly transfer to reservoir under the wind regime exsiccator can't the situation of proper functioning; If the wind regime exsiccator recovers proper functioning, switching spool can automatically reset.The utility model good seal performance is switched highly sensitive.In addition, the utility model does not adopt spring and automatically resets with air, has avoided the spring long defective that causes flexibility decrease to reset service time, and non-corrosive is not aging.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model
(5) embodiment
With reference to accompanying drawing 1:
The utility model comprises:
Valve body 1, intake duct 10 and be connected with the main air outlet channel 11 of filtrating equipment, also have on the valve body: be communicated with the auxilliary air outlet channel 12 of intake duct, auxilliary air outlet channel 12 connects to reservoir.Can seal the switching spool of main air outlet channel or auxilliary air outlet channel; Switch spool and comprise valve 6, valve 7, with the valve rod that valve 6, valve 7 are linked to each other.Switch spool and be slidably mounted in the sliding-groove 14 in the valve body 1, an end that switches spool is exposed to intake duct, and the other end is exposed to high pressure air cavity 13; The high pressure air cavity 13 that is used to promote to switch spool connects a controlled high-pressure air source; Switch between spool and the sliding-groove Sealing is housed, Sealing also is equipped with in sealing place of described switching spool and main air outlet channel 11 and auxilliary air outlet channel 12.
The switching spool is positioned at auxilliary air outlet channel 11 ends and 14 of sliding-grooves are lined with valve pocket 5
Be equipped with on the intake duct and switch the valve seat 2 that spool matches.
Also have three bases 4 on the valve body 1, logical respectively intake duct, main air outlet channel and auxilliary air outlet channel have Sealing between base 4 and the valve body 1.Valve gap 8,9 is arranged on the valve body 1, porosely on the valve gap 8 communicate, between valve gap and the valve body Sealing is arranged with high pressure air cavity 13.
Under the normal condition, the pressure of high pressure air cavity 13 makes the valve 7 and intake duct closure that switch spool than the pressure height of intake duct 10, valve 6 is not closed with intake duct, and main air outlet channel communicates with intake duct, after air flows into from intake duct, flow to air drier by main air outlet channel, lead to reservoir after filtering again.When the wind regime exsiccator can't proper functioning, open the high-pressure air source that links to each other with air cavity 13 by electrically-controlled valve, high-pressure air source is to air cavity 13 input pressurized gas.Air cavity 13 pressure promote to switch spool and make valve 6 and intake duct closure greater than intake duct pressure, and valve 7 is not closed with intake duct, and air directly flows to reservoir by auxilliary air outlet channel after flowing into from intake duct.Like this, under the wind regime exsiccator can't the situation of proper functioning, do not influence the locomotive proper functioning yet.After wind regime exsiccator proper functioning, close electrically-controlled valve, air cavity 13 pressure recover normally again less than intake duct pressure, and the switching spool is pushed and resets, and air flows to the wind regime exsiccator from main air outlet channel, recovers proper functioning.Switch spool and be positioned between auxilliary air outlet channel end and sliding-groove and be lined with valve pocket, make switch spool here end face be able to smaller, and can the freedom activity after switching spool and valve pocket cooperating.Like this, when resetting, according to air specific pressure principle, air effect is bigger in the pressure of this side end face, more helps promoting to switch valve core reset.Valve seat on the intake duct more helps valve 6,7 and intake duct is sealed and matched.
