Abstract
An aeration pipe orifice device, which is connected with an aeration pipe on the base of a thermostat, is characterized in that an orifice block is arranged in the mouth of the aeration pipe. An orifice is processed in the center of the orifice block, the outer diameter transitionally fits the inner diameter of the aeration pipe, thereby resolving the problem. Since the orifice block adopted is in a simple structure, the inner diameter of the orifice on the orifice block added on the designed aeration pipe can be properly adjusted according to the performance requirements, and suitable profiled pipes can be selected according to a connecting pipe to match the outer diameter, thereby realizing the purposes of convenient processing and weight reduction as well as the prevention of leakage in the connection with a rubber pipe.
Description
Technical field
The present invention relates to a kind of vehicular engine Center Vent tube metering orifice device, especially relate to thermostat place vent pipe metering orifice device in a kind of motor.
Background technique
In the design of engine water jacket, because the needs that complete machine is arranged, the water jacket water outlet often is lower than the engine water jacket peak, gas in the water jacket can not be discharged by the thermostat place, need before thermostat, open pore in addition in the peak place of water jacket, the gas of herein drawing is directly received expansion tank, participate in major cycle, if caliber is excessive, can cause water temperature low during winter, general internal diameter just can meet the demands in Φ 2 millimeter, because process limitation, the rubber pipe internal diameter that links with it can not be accomplished less than 5 millimeters, though it is little that the nylon tube internal diameter can be done, can't solve connectivity problem, therefore, at present engine water jacket gas removing pipe external diameter is generally all 8 millimeters of Φ, (the expansion tank suction port caliber that links with it is 8 millimeters of Φ).Guarantee 2 millimeters of the internal diameter Φ of vent, guarantee 8 millimeters of outside dimension Φ simultaneously, can not use existing type pipe, must special processing.Current state be otherwise wall thickness blocked up, or external diameter is too thin.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the deficiency of existing vent pipe metering orifice device, and provides a kind of simple in structure, vent pipe metering orifice device that the aperture is adjustable.The internal diameter and the external diameter that guarantee breathing pipe all satisfy performance requirement.
The present invention solves the problems of the technologies described above to adopt following technological scheme:
A kind of vent pipe metering orifice device, interface breathing pipe on thermostat base is characterized in that: add a metering-orifice piece in the interface ventilation mouth of pipe.Metering-orifice of processing in the middle of the metering-orifice piece, the internal diameter transition fit of the external diameter of metering-orifice piece and breathing pipe, thus address the above problem.
Good effect of the present invention is, owing to only adopt metering-orifice piece simple in structure.In designed breathing pipe, add the metering-orifice piece, can suitably adjust the metering-orifice internal diameter according to performance need, the type pipe that external diameter can be suitable according to the connecting tube match selection, thus realizing being convenient to processes, loss of weight and avoid defective with gas leakage aspect, rubber pipe joint.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is an organigram of the present invention.
1. metering-orifice piece, 2. breathing pipe, 3. thermostat base
Embodiment
In Fig. 1, a kind of vent pipe metering orifice device on thermostat base 3, adds a metering-orifice piece 1 in 2 mouthfuls of the interface breathing pipes.Metering-orifice of processing in the middle of the metering-orifice piece, the aperture is adjustable.The internal diameter transition fit of the external diameter of metering-orifice piece 1 and breathing pipe.
Claims (2)
1. a vent pipe metering orifice device that is used for the engine cylinder-body cooling jacket comprises thermostat base (3), goes up interface breathing pipe (2) at thermostat base (3), it is characterized in that: add a metering-orifice piece (1) in interface breathing pipe (2) mouth.
2. vent pipe metering orifice device according to claim 1 is characterized in that: the external diameter of described metering-orifice piece (1) and the internal diameter transition fit of breathing pipe.
