Abstract

The utility model discloses a plastic expansion tank which is characterized in that a water supplying port is arranged on the top end of a tank body, a venting hole is arranged on the side wall of the water supplying port, a pressure cover is screwed on the water supplying part, a water tank side connecting port is further arranged on the side wall of the tank body, a water outlet connecting copper pipe and a water inlet connecting copper pipe are respectively arranged on two side ends of the tank body, a water tank lower connecting port is arranged on the bottom of the tank body, and both ends of a liquid level observing pipe are connected with a connecting pipe and are fixed by a connecting clamp. Through the arrangement, the plastic expansion tank has the advantages of stronger gluing force, aging resistance, good toughness, light weight, low cost and the like.

Description

The plastic expansion water tank

Technical field

The utility model relates to the automobile radiators assembly, definite a kind of auxiliary water tank that is used to be connected on the radiator of saying so.

Background technology

Existing heavy motor vehicle expansion tank, material are the copper metal, though continued for many years, have 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 expansion of metal water tank, influences cooling performance; 3. the expansion tank filler cap of original metallic material separates with pressure valve, the manufacturing process complexity, and cost increases; 4. the expansion tank weight of metallic material is bigger, does not meet the requirement of heavy goods vehicles weight-saving; 5. the expansion 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 utility model remedies the prior art deficiency exactly, and a kind of automobile plastic expansion tank is provided, and the utlity model has withstanding corrosion, in light weight, rational in infrastructure, easy for installation, characteristics such as integrated cost is low.

The utility model is finished by following technical measures:

The utility model is provided with the filler on the top of casing, on the sidewall of filler, be provided with exhausr port, pressure cover is screwed on the filler, on the sidewall of casing, also be provided with a water tank side communication port, water outlet connects copper pipe and is connected the two side ends that copper pipe is located at casing respectively with water inlet, communication port is located at the bottom of casing under the water tank, and the two ends of liquid level observation tube link to each other with connection pipe and fixed by Connection Card.Casing adopts black atactic copolymerized polypropene plastics to make, and this material has stronger cohesive force, ageing-resistant, good toughness, in light weight, low cost and other advantages.In use, weld seam is not easy cracking; The expansion tank of plastic material is rational in infrastructure, and dirt is easily discharged; Blow off valve is produced on the filler cap, forms pressure cover, has reduced production process.

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. the filler, 3. connection pipe, 4. pressure cover, 5. water outlet connects copper pipe, 6. water inlet connects copper pipe, 7. water tank side communication port, 8. communication port under the water tank, 9. Connection Card, 10. liquid level observation tube, 11. exhausr ports.

The specific embodiment

As shown in Figure 1, the utility model is provided with filler 2 on the top of casing 1, on the sidewall of filler 2, be provided with exhausr port 11, pressure cover 4 is screwed on the filler 2, on the sidewall of casing 1, also be provided with a water tank side communication port 7, the water outlet that links to each other with radiator is connected copper pipe 5 and is connected the two side ends that copper pipe 6 is located at casing 1 respectively with water inlet, and communication port 8 is located at the bottom of casing under the water tank, and the two ends of liquid level observation tube 10 link to each other with connection pipe 3 and be fixing by Connection Card 9.

Claims

1, plastic expansion water tank, it is characterized in that: the top at casing is provided with the filler, on the sidewall of filler, be provided with exhausr port, pressure cover is screwed on the filler, on the sidewall of casing, also be provided with a water tank side communication port, water outlet connects copper pipe and is connected the two side ends that copper pipe is located at casing respectively with water inlet, and communication port is located at the bottom of casing under the water tank, and the two ends of liquid level observation tube link to each other with connection pipe and fixed by Connection Card.
