Abstract
The utility model discloses a plastic expansion tank which is characterized in that a water supplying pipe is arranged on the top end of a tank body, a pressure cover is screwed on the water supplying pipe, a discharge pipe is arranged on the top end of the water supplying pipe, two air exhaust openings are arranged on the tank body, a connecting port is further connected on one end of the tank body, a metallic screw nut is connected with the tank body into a whole, and four mounting holes are arranged on the center position of the tank body. Through the arrangement, the plastic expansion tank has the advantages of corrosion prevention, light weight, simple structure, convenient mounting and low integrative cost.
Description
Technical field:
The utility model relates to car engine cooling system, definite a kind of auxiliary water tank that is used to be connected on the car engine cooling system of saying so.
Background technology:
The secondary water tank of existing automobile, material is the copper metal, though continued for many years, has following defective always: 1. in vehicle traveling process, the weld cracking phenomenon often occurs, cause refrigerant fluid to run off, influence normal cooling performance; 2. existing expansion of metal cisten mechanism is also unreasonable, after after a while, on the inwall of the dirt of the inside attached to the secondary water tank of metal, influences cooling performance; 3. the secondary tank filler opening lid of original metallic material separates with pressure valve, the manufacturing process complexity, and cost increases; 4. the secondary water tank weight of metallic material is bigger, does not meet the requirement of heavy goods vehicles weight-saving; 5. the secondary water tank of metallic material is raw MAT'L with copper, and price is higher, and integral vehicle cost is increased.
Summary of the invention:
The secondary water tank of the utility model plastics remedies the prior art deficiency exactly, and a kind of secondary water tank of automobile plastic that liquid spill, body heat up that solves is provided, the secondary water tank withstanding corrosion of plastics, in light weight, simple in structure, easy for installation, integrated cost is low.
The utility model is finished by following technical measures:
Be provided with a filler pipe on casing, pressure cover is screwed on the filler pipe, is provided with a freeing pipe on the top of filler pipe, two exhausr ports are located on the casing, end at casing also is provided with a communication port, and metal nuts and casing link together, and is provided with four mounting holes at the midway location of casing.Casing adopts translucent vinyon to make, and is that raw-material secondary water tank has good toughness and self cohesive force with plastics.And withstanding corrosion, in light weight, simple in structure, easy for installation, advantage such as integrated cost is low, in use, weld seam is not easy to crack; The secondary cisten mechanism of plastic material is simple, and dirt is easily discharged; Blow off valve is produced on the filler cap, forms pressure cover, has reduced manufacture craft, has reduced cost; Secondary water tank of plastics and car engine cooling system are connected to a fixed in the back of automobile cab, and be during liquid make-up, very convenient.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further described
Fig. 1 is the utility model integral structure scheme drawing
Among Fig. 1: 1. casing, 2. pressure cover, 3. exhausr port, 4. filler pipe, 5. freeing pipe, 6. communication port, 7. nut.
The specific embodiment:
As shown in Figure 1, casing 1 adopts translucent vinyon to make, establish a filler pipe 4 in the upper end of casing 1, pressure cover 2 is screwed on the filler pipe 4, when the pressure in the casing surpasses 0.05MPa, pressure cover 2 self-bleedings, discharge through freeing pipe 5, there are two exhausr ports 3 upper end of casing 1, under the normal circumstances, the gas that produces in the casing 1 is discharged thus, below casing 1, there is a communication port 6 to be connected, establishes the nut 7 that a bronze medal metal is made in the lower end of casing 1, be used for installing temperature measurer with car engine cooling system, establish 4 mounting holes in the centre of casing 1, the secondary water tank of plastics is installed on the vehicle body by mounting hole.
