Abstract
The utility model provides a trailer brake control valve assembly which is composed of a valve body, wherein an air inlet connector and a one-way valve are arranged in a control opening of the valve body; the one-way valve is arranged in a circle groove at the inner end of the air inlet connector, and is communicated with the interior of the air inlet connector through communicating pores arranged in the circle groove. The brake control valve assembly of the utility model uses the air inlet connector and the circle one-way valve at the control opening to realize air intake control, the structure of the control opening is compact and simple, and the parts are few and have good tightness.
Description
Technical field
The utility model relates to a kind of trailer brake control valve assembly.
Background technology
The trailer brake control valve assembly is installed on the main car, and main car is inflated to the trailer air receiver continuously by it; No matter main car is the braking of breaking, leak gas, or stopping brake, and the trailer brake control cock can prevent effectively that trailer from producing the braking stack; When associated line breaks, leaks (breaking off relations as main car and trailer), can make trailer and main car produce synchronous braking automatically, thereby guarantee running safety, but present trailer brake control valve assembly structure is its control mouthful place particularly, generally form the many and complex structure of number of parts by inlet suction port, spring perch, valve spring, check valve.
Summary of the invention
The utility model provides a kind of trailer brake control valve assembly, and its control of this trailer brake control valve assembly mouthful place is simple and compact for structure, and number of parts is few, good seal performance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of trailer brake control valve assembly, constitute by valve body, it is characterized in that: in the control mouth of described valve body, be provided with inlet suction port and check valve, the inner sealing of described inlet suction port, described check valve is located in the annular recess of inlet suction port the inner, and by being located at intercommunicating pore and the inlet suction port internal communication in the annular recess.
The utility model is owing to adopt technique scheme, and a control mouthful place establishes inlet suction port and belt check valve is realized air inlet control, makes the control mouthful very simple compactness of place's structure, the few and good seal performance of number of parts.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cutaway view among Fig. 1;
Fig. 3 is a B-B cutaway view among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, be trailer brake control valve assembly of the present utility model, constitute by valve body 2, valve body is provided with an admission port 1, a control mouth 4, an exhausr port 3, an inflation inlet 25, four air extractor ducts 21,22,23,24, be provided with inlet suction port 5 in the valve body from top to bottom successively, check valve 6, piston 7, check valve 8, valve 9, exhaust joint 10, check valve 15, valve spring 14, valve seat 13, pressure spring 12, guide holder 11, described check valve 6 is located in the annular recess 51 of inlet suction port 5 the inners, and by being located at the intercommunicating pore 52 and inlet suction port 5 internal communication in the annular recess.Use this structure can omit existing spring perch, the valve spring of controlling in the mouth structure.Compared with prior art, the utlity model has advantages such as simple in structure, compact and favorable sealing property.
The utility model is applicable to all kinds of trailers.
