The utility model discloses a check valve of automobile and engineering machinery brakes system, comprising a valve body (1), a one-way cock assembly (6) and a one-way valve spring (4), on the valve body (1) is equipped with an air intake port and an air outlet port, the one-way valve spring (4)is mounted on a spring holder (3), in the one side of the spring holder (3) towards one side of the air outlet port, establishes a spring pedestal (7), between the spring holder (3) and the spring pedestal (7), establishes a retaining ring (2). By adopting the technical scheme, retrofit to the structure of existing product and design and the update, simplified the product structure, shortened the production cycle, lower costs, improved the productivity and the performance of product, avoided the phenomenon of many plays leakage, thereby improved the performance and the service life of product, laid the basis for various vehicle assembles in enormous quantities.
Description
Technical field
The utility model belongs to the technical field of automobile and engineering machinery, relates to the braking system of automobile and engineering machinery, and more particularly, the utility model relates to the one-way valve of a kind of automobile and engineering machinery braking system.
Background technique
In the prior art, the one-way valve internal structure complexity that the commercial car diesel fuel system is used, cost is higher.
Shown in Figure 1 as in this Figure of description, the one-way valve of automobile and engineering machinery use for brake system comprises valve body 1, check valve spring 4, one-way cock assembly 6, described check valve spring 4 is fixing by spring seat 3, described one-way cock assembly 6 is by O-ring seals 5 sealings, and back-up ring 2 makes described spring seat 3 axially locating.
In said structure, described O-ring seals 5 is fragile, and O-ring seals 5 and valve body 1 contact seal easily cause leakage, influence product performance.
The model utility content
Problem to be solved in the utility model provides the one-way valve of a kind of automobile and engineering machinery braking system, its objective is the raising reliability of products.
To achieve these goals, the technological scheme taked of the utility model is:
The one-way valve of automobile provided by the utility model and engineering machinery braking system, comprise valve body, one-way cock assembly and check valve spring, described valve body is provided with the air inlet port and the port of giving vent to anger, described check valve spring mounts elastically, in the one side of described spring seat towards the port of giving vent to anger, if spring pedestal between described spring seat and spring pedestal, is established back-up ring.
The spool of described one-way cock assembly is inserted in the described spring base hole, and cooperates with described spring seat formation.
The utility model adopts technique scheme, structure to existing product is carried out Transform Type design and update, simplified product structure, shortened the manufacture cycle, reduce cost, improved the production capacity and the performance of product, avoided having more the phenomenon of leakage, thereby improve the performance and the working life of product, for the assembling in enormous quantities of various vehicle lays the foundation.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is the related structural representation of specification background technique part;
Fig. 2 is a structural representation of the present utility model.
Be labeled as among the figure:
1, valve body, 2, back-up ring, 3, spring seat, 4, check valve spring, 5, O-ring seals, 6, the one-way cock assembly, 7, spring pedestal.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 2, it is the one-way valve of a kind of automobile and engineering machinery braking system, the energy supplying device that belongs to automobile and engineering machinery braking system comprises valve body 1, one-way cock assembly 6 and check valve spring 4, and described valve body 1 is provided with the air inlet port and the port of giving vent to anger.One-way valve is threaded with pipeline by the air inlet port and realizes gas delivery.
Under normal conditions, one-way cock assembly 6 is in the contact seal state with the valve port of valve body 1.In working order down, to the air inlet of one-way valve air inlet port, when air pressure reaches one regularly, air pressure promotes one-way cock assembly 6 to the right, makes valve and valve port break away from one-way valve board on state, and during the gas reverse flow, because the effect of check valve spring, valve port is in closed condition, makes one-way valve be in cut-off state.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize improving the goal of the invention of reliability of products, the technological scheme that the utility model is taked is:
The one-way valve of automobile provided by the utility model and engineering machinery braking system, described check valve spring 4 is installed on the spring seat 3, in the one side of described spring seat 3 towards the port of giving vent to anger, establishes spring pedestal 7, between described spring seat 3 and spring pedestal 7, establish back-up ring 2.
Adopt technique scheme,, make its pipeline air pressure keep stable operation to keep degree of vacuum or compressed air pressure.
The one-way valve that provides of the present utility model promptly reduces unnecessary part, has increased necessary new parts again; With the improvement of one-way cock assembly structure, O shape circle has been omitted, increased a part spring seat 7 simultaneously, the new structure part is convenient to processing and is installed, and has reduced operation easier.
The utility model has been simplified product structure, has shortened the manufacture cycle, has improved the production capacity and the performance of product, has reduced purchase cost, for the assembling in enormous quantities of various vehicle lays the foundation.
The spool of one-way cock assembly 6 described in the utility model is inserted in described spring seat 3 holes, and cooperates with described spring seat 3 formation.
Above-mentioned one-way valve has improved one-way valve inner body structure; Component structurals such as spring seat 3, check valve spring 4 and one-way cock assembly 6 are all improved, strengthened the sealing of its product.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
