Abstract
The invention discloses a piston type dual-way check valve for a diesel engine brake system of a commercial vehicle. The valve comprises a valve body (3), a valve plunger (2), two air inlet joints (1) and an air outlet joint (6) and is characterized in that: an O-shaped seal ring (5) is arranged at the connection position of the valve body (3) and the air inlet joints (1). After the technical scheme is adopted to remodel and upgrade the traditional product, the reliability of the product is improved; the structure of the product is simplified; the production period is shortened; the cost is reduced; the yield and the performance of the product are improved; and the phenomenon of excess leakage is avoided. Therefore, the performance of the product is improved; the service life of the product is prolonged; and the valve lays a foundation for massive assembly of various vehicles.
Description
Technical field
The invention belongs to the technical field of commercial car diesel engine, relate to commercial car diesel engine braking system control gear, more particularly, the present invention 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.
Summary of the invention
Problem to be solved by this invention 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 present invention is:
Commercial car diesel engine braking system piston type bilateral one-way valve provided by the present invention 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 present invention 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 invention.
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 the specific embodiment of the present invention 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 invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present invention structure expressed as Fig. 2, the present invention is a kind of commercial car diesel engine braking system piston type bilateral one-way valve, comprises 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 present invention takes is:
Commercial car diesel engine braking system piston type bilateral one-way valve provided by the present invention 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.
Bilateral one-way valve provided by the invention 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.
Technological scheme of the present invention 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 of the present invention 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 present invention simplifies, 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 of the present invention 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 present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
