The technical scheme is adopted to improve, design and upgrade the structure of the existing product, so that the reliability of the product is improved, the product structure is simplified, the production period is shortened, the cost is reduced, the capacity and the performance of the product are improved and the phenomenon of leakage at a plurality of positions is avoided, and thus, the performance of the product is improved, the service life of the product is prolonged and the foundation is laid for mass assembly of various vehicles.
Description
Technical field
The utility model belongs to the technical field of commercial car diesel engine, relates to commercial car diesel engine braking system control gear, and more particularly, the utility model relates to a kind of commercial car diesel engine braking system piston type bilateral one-way valve.
Background technique
In the prior art, used piston type bilateral one-way valve in the commercial car diesel engine braking system, its complex structure, cost is higher.
Shown in Figure 1 as in this Figure of description is provided with packing ring 4 between valve body 3 and air input joint 1 end face surface of contact.The complex structure of air input joint 1, fragile; In the joint of air input joint 1 with valve body 3, easily cause leakage, influence product performance.
The prior art constructions air input joint adopts the VOSS interface, and is fragile; And the size and the weight of product are bigger.Prior art constructions also is provided with mounting bracket 7, complex structure, and processing and mounting hardness are bigger.
The model utility content
Problem to be solved in the utility model provides a kind of commercial car diesel engine braking system piston type bilateral one-way valve, its objective is the reliability that improves piston type bilateral one-way valve.
To achieve these goals, the technological scheme taked of the utility model is:
Commercial car diesel engine braking system piston type bilateral one-way valve provided by the utility model comprises valve body, valve piston, two air input joints and an air outlet adapter, in the joint of described valve body and air input joint, establishes O-ring seals.
Described air input joint adopts the regular screw threads linkage structure.
Described valve body is fixedly connected on the described braking system gas circuit pipeline by two air input joints.
The utility model adopts technique scheme, structure to existing product is carried out Transform Type design and update, improved reliability of products, simplified product structure, shortened the manufacture cycle, reduced cost, the production capacity and the performance of product have been improved, avoided having more the phenomenon of leakage, thereby improved 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 described structural representation of this specification background technique;
Fig. 2 is a structural representation of the present utility model.
Be labeled as among the figure:
1, air input joint, 2, valve piston, 3, valve body, 4, packing ring, 5, O-ring seals, 6, air outlet adapter, 7, mounting bracket.
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, the utility model are a kind of commercial car diesel engine braking system piston type bilateral one-way valve, comprise valve body 3, valve piston 2, two air input joints 1 and air outlet adapters 6.Valve piston 2 is contained in the valve body 3.Between valve body 3 and air input joint 1 end face surface of contact, be provided with packing ring 4.
The bilateral one-way valve is threaded with pipeline by air input joint and realizes gas delivery.When to air input joint 1 air inlet of a port of bilateral one-way valve (as left end), valve piston 2 is to another port (right-hand member) motion, and with air input joint 1 contact seal of this end; On the contrary, when gas during, 2 end motions left of valve piston from air input joint 1 air inlet of right output port, and with air input joint 1 contact seal of this end.Therefore, no matter gas from which air input joint 1 enters, gas all flows out from air outlet adapter 6.
So, with two independently gas circuit alternately to same gas-pressure component or to a pilot line inflation; When wherein a gas circuit is damaged, can come air feed by another gas circuit, the pipeline gas circuit can normally be moved.
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 the goal of the invention of the reliability of raising piston type bilateral one-way valve, the technological scheme that the utility model is taked is:
Commercial car diesel engine braking system piston type bilateral one-way valve provided by the utility model comprises valve body 3, valve piston 2, two air input joints 1 and air outlet adapters 6, in the joint of described valve body 3 with air input joint 1, establishes O-ring seals 5.
The bilateral one-way valve that the utility model provides has increased seal arrangement and has set up O-ring seals 5 in air input joint 1 and valve body 3 joints, has improved the sealing of product.
The technical solution of the utility model is carried out Transform Type design and update to the structure of existing product, has improved reliability of products, reduces cost, and improves performance, has avoided having more the phenomenon of leakage, thereby improves the performance and the working life of product.Simplified product structure, shortened the manufacture cycle, improved the production capacity and the performance of product, reduced purchase cost, for the assembling in enormous quantities of various vehicle lays the foundation.
Air input joint 1 described in the utility model adopts the regular screw threads linkage structure.
Technique scheme has been simplified the linkage structure in original technology; The original structure air input joint adopts the VOSS interface, and is fragile.The utility model is simplified, and is connected by the VOSS interface to change the regular screw threads connection into, has improved the structure of product; Dwindle the air input joint size simultaneously, alleviated product weight.
Valve body 3 described in the utility model is fixedly connected on the described braking system gas circuit pipeline by two air input joints 1.
Technique scheme has been improved valve body structure; The existing product valve body has mounting bracket, complex structure.The new structure valve body is convenient to processing and is installed, and has reduced operation easier.
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.
