Abstract
The utility model discloses a control line for an exhaust brake butterfly valve and relates to a gas line used between an engine and a cylinder. The utility model aims to provide the control line, which is low in cost and suitable for high-temperature and vibration occasions, for the exhaust brake butterfly valve. The control line for the exhaust brake butterfly valve provided by the utility model comprises a metal hose (3) and a rubber hose (7), and is characterized by also comprising a joint (5), wherein one end of the rubber hose (7) is connected with the joint (5); the other end of the joint (5) is connected with the metal hose (3); the metal hose (3) can normally work at the high temperature of 500 DEG C; the other end of the metal hose (3) is connected with the gas port of a control cylinder (2); a distance exists between the joint (5) and the control cylinder (2).
Description
Technical field
The utility model relates to a kind of pipeline, particularly relates to a kind of for the gas piping between motor and cylinder.
Background technique
Exhaust brake butterfly valve pilot line is used for connecting source of the gas and exhaust brake butterfly valve control cylinder, carry out the flexible of control cylinder piston by gas circuit pressure, thereby control the opening and closing of exhaust brake butterfly valve valve block, during due to control cylinder piston action, pipeline also can move thereupon, therefore in the design of this pilot line, all adopt and flexibly connect both at home and abroad, relatively more conventional is rubber hose and metallic hose, but because exhaust brake butterfly valve is often arranged near engine exhaust flange one side, peripheral temperature is up to 500 degree Celsius, rubber hose cannot be in long-term work under high temperature condition, metallic hose is expensive, cost performance is lower.
Model utility content
The technical problems to be solved in the utility model is to provide the exhaust brake butterfly valve pilot line that a kind of cost is low, be applicable to high temperature and vibration occasion.
A kind of exhaust brake butterfly valve of the utility model pilot line, comprises metallic hose and rubber hose, wherein also comprises joint, one end jointing of described rubber hose.The other end connection metal flexible pipe of described joint.Described metallic hose can normally be worked under the high temperature of 500 degree Celsius.The other end of metallic hose connects the gas port of control cylinder.Described joint and control cylinder have distance.
The utility model exhaust brake butterfly valve pilot line, wherein metallic hose is bent into " Z " shape structure.
The utility model exhaust brake butterfly valve pilot line, wherein said joint is fixed on the mounting hole of motor by adapter bracket.
The utility model exhaust brake butterfly valve pilot line difference from prior art is that the utility model exhaust brake butterfly valve pilot line is by control cylinder connection metal flexible pipe, metallic hose connects rubber hose by joint, replace all the whole piece pipeline by connection by metal hose, make pipeline guarantee, under the condition of high-temperature operation and vibration service, to reduce pipeline user cost and maintenance cost.
In the utility model exhaust brake butterfly valve pilot line, metallic hose is bent into " Z " font.In the time of the piston action of control cylinder, rigidly connected pilot line also can move thereupon with it." Z " shape structure of steel pipe can adapt to this movement.Effectively alleviate from the vibration between motor and exhaust brake butterfly valve control cylinder simultaneously.Exhaust brake butterfly valve pilot line comprises metallic hose and joint two-part, simple in structure.Joint is fixedly mounted on by support on the mounting hole of motor, also can reduce the vibration between motor and exhaust brake butterfly valve control cylinder, strengthens stability.
Below in conjunction with accompanying drawing, exhaust brake butterfly valve pilot line of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the utility model exhaust brake butterfly valve pilot line embodiment 1 structural representation.
Embodiment
As shown in Figure 1, the utility model exhaust brake butterfly valve pilot line comprises joint 5 and metallic hose 3.Described metallic hose 3 can normally be worked under the high temperature of 500 degree Celsius.The model of the diameter of metallic hose 3 and described joint 5 is chosen according to the concrete pressure that makes the action of engine exhaust and brake butterfly valve.Joint 5 is fixedly mounted on the mounting hole of motor by adapter bracket 6.Joint 5 one end connect rubber hose 7, the other end connection metal flexible pipe 3 of joint 5.The other end of metallic hose 3 connects the gas port of control cylinder 2.Described exhaust brake butterfly valve 1 and control cylinder 2 are for being rigidly connected.Metallic hose 3 is bent into " Z " shape structure.Described joint 5 and control cylinder 2 have distance.
When work, exhaust brake butterfly valve pilot line assembly connects control cylinder 2 and rubber hose 7.When receiving after the instruction of exhaust brake butterfly valve unlatching, the cavity of exhaust brake butterfly valve pilot line assembly and control cylinder 2 is full of rapidly the air pressure of 0.8Mpa, piston on gas push cylinder stretches out, and drives closing of braking butterfly valve 1 interior valve block, thereby realizes motor 4 exhaust brakes.In the time of the piston action of control cylinder 2, rigidly connected pilot line also can move thereupon with it, and " Z " shape structure of metallic hose 3 can adapt to this movement, effectively alleviates from the vibration between motor 4 and exhaust brake butterfly valve control cylinder 2 simultaneously.
Can be bent into other suitable shapes according to the rotational travel pilot line of exhaust brake butterfly valve control cylinder afterbody, optimize steel-pipe construction.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
Claims (3)
