Abstract
The utility model provides a novel vehicle hand brake valve. The novel vehicle hand brake valve comprises an upper valve body (2) and a lower valve body (5); a piston assembly (3) and a valve (6) are arranged in a cavity composed of the upper valve body (2) and the lower valve body (5); a cam assembly (1) is arranged on an ejector rod at the upper end of the piston assembly (3); the cam of the cam assembly (1) is used for controlling the opening and closing of the valve (6); the lower valve body (5) is provided with an air outlet (7), an air inlet (8) and an exhaust port (9); a filter screen (4) is arranged on the cavity of the lower valve body (2) between the air inlet (8) and the air outlet (7); the air inlet (8) is communicated with the valve (6) by use of the filter screen (4). As the filter screen structure mounting manner and the filter screen structure are improved on the basis of the traditional hand brake valve, reliable filtering effect can be achieved; besides, the filter screen is annular so that the air inlet area is increased and reliable air inlet/outlet effect is guaranteed. The novel vehicle hand brake valve is capable of guaranteeing the filtering effect without affecting the braking effect.
Description
Technical field
The utility model relates to a kind of vapour vehicle accessory, especially relates to a kind of vehicle hand brake activation valve.
Background technology
In automobile air brake system, the parts such as part joint, storage tank, pipeline all can adopt metallic material manufacture.And these metal partss are along with the automobile growth of tenure of use, the phenomenons such as generation corrosion that can be gradually.These corrosion things can enter along with braking procedure the sealing part of hand brake valve in air braking system, thereby cause the earlier period damage phenomenons such as the gas leakage of hand brake valve.And, in workman's fitting process, also very easily occur that foreign material enter the phenomenon of system pipeline.
For this phenomenon, under normal circumstances, can load onto stainless steel wire filtering net at the turnover gas interface of hand brake valve, to isolate foreign material, hand brake valve internal core valve is caused to damage.But, because product interface aperture is limited, after the time is permanent, easily cause the phenomenons such as interface filtering net congestion affects braking effect.Particularly current popular VOSS interface structure, its aperture only has 1/3rd of traditional hand valve, and filtering net cannot be installed in less aperture at all on interface.
Utility model content
The utility model object is to overcome existing above-mentioned existing problems, and a kind of skeleton type filtering net installation of large latus rectum is provided, and in guaranteeing reliably to filter foreign material, does not affect again the reliability of product turnover gas.
The technical scheme that the technical matters that the utility model solves adopts is:
A kind of novel automobile hand brake valve, comprise upper valve body 2 and lower valve body 5, in the cavity that upper valve body 2 and lower valve body 5 form, be provided with piston assembly 3 and valve 6, the push rod of piston assembly 3 upper ends is provided with Cam set assembly 1, the switching of the cam-operated valve door 6 of Cam set assembly 1, lower valve body 5 is provided with air extractor duct 7, admission port 8 and exhausr port 9, it is characterized in that the cavity between admission port 8 and the air extractor duct 7 of lower valve body 2 is provided with filtering net 4, and admission port 8 is by filtering net 4 and valve 6 conductings.
When concrete enforcement, the cavity of lower valve body 5 is fixed with polyamide skeleton and is fixed on, and above-mentioned filtering net 4 is located on polyamide skeleton.
When concrete enforcement, filtering net 4 is stainless steel wire filter screen or nylon leaching net.
In filtering net, be provided with the part such as valve, piston assembly, between each part, use rubber seal rings for seal, form individual cavity separately.
The beneficial effects of the utility model are: the utility model has improved filter screen structure installation form and filter screen structure on the basis of traditional hand brake valve, not only can realize the reliable of filter effect, and circular filter net increased air inlet area, ensure the reliable of turnover gas effect.In ensureing filter effect, do not affect again braking effect.
Detailed description of the invention
In Fig. 1, a kind of novel automobile hand brake valve, a kind of novel automobile hand brake valve, comprise upper valve body 2 and lower valve body 5, in the cavity that upper valve body 2 and lower valve body 5 form, be provided with piston assembly 3 and valve 6, the push rod of piston assembly 3 upper ends is provided with Cam set assembly 1, the switching of the cam-operated valve door 6 of Cam set assembly 1, lower valve body 5 is provided with air extractor duct 7, admission port 8 and exhausr port 9, it is characterized in that the cavity between admission port 8 and the air extractor duct 7 of lower valve body 2 is provided with filtering net 4, filtering net 4 is on polyamide skeleton, polyamide skeleton is fixed in the cavity of lower valve body, filtering net 4 is stainless steel wire filter screen or nylon leaching net, in filtering net 4, be provided with valve 6, piston assembly 3 parts such as grade, between each part, use rubber seal 10 to seal, form individual cavity admission port 8 separately and pass through filtering net 4 and valve 6 conductings.
When concrete use, admission port 8 is in aeration status, and the push rod of piston assembly 3 upper ends, according to Cam set assembly 1 in-profile different depth, is opened valve 6.The pressurized air of admission port 8, by filtering net 4, through valve 6, is exported from air extractor duct 7.When the Cam set assembly 1 of upper valve body 2 upper ends is according to External Force Acting, carry out after clickwise.The push rod of piston assembly 3 upper ends is according to Cam set assembly 1 in-profile different depth, valve-off 6.The pressurized air of air extractor duct 7, by air flue, is discharged from exhausr port 9.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
