AI Technical Summary

Technical Problem

Existing valve covers cannot detect whether the valve stem is leaking; they only have a dustproof function and lack practicality.

Method used

Design a valve cover with a monitoring hole and an elastic leak tester. The elastic leak tester in the monitoring hole detects whether the valve nozzle is leaking. The sealing effect is achieved by combining a sealing ring and sealant. The outer wall is provided with anti-slip texture to facilitate rotation.

Benefits of technology

It enables rapid and practical valve leak detection, improves driving safety, and is low in cost and has a novel structure.

Description

TECHNICAL FIELD

[0001] The utility model relates to a valve cover, especially a valve cover for measuring air leakage of valve nozzle. BACKGROUND

[0002] The valve nozzle is arranged on the automobile tire and is used for inflating the tire, and the valve nozzle will be damaged and leak after long time use. At present, a valve cover is usually threadedly connected on the valve nozzle, and the valve cover only has a dustproof function, for example, does not have the function of detecting whether the valve nozzle leaks. SUMMARY

[0003] The utility model solves the technical problem of the prior art and provides a valve cover for measuring air leakage of valve nozzle.

[0004] In order to achieve the above purpose, the utility model takes the following measures:

[0005] A valve cover for measuring air leakage of valve nozzle, which comprises a valve cover body, an opening is arranged at the inner end of the valve cover body, an inner thread is arranged in the opening and is used for threadedly connecting the valve nozzle, a monitoring hole is arranged at the outer end of the valve cover body and is communicated with the opening, and an elastic leak detection sheet is sealingly arranged in the monitoring hole.

[0006] An anti-skid pattern is integrally formed on the outer wall of the valve cover body.

[0007] A sealing step surface is formed between the monitoring hole and the inner wall of the valve cover body, and a sealing ring is integrally formed at the edge of the elastic leak detection sheet and is used for sealingly cooperating with the sealing step surface.

[0008] The sealing ring and the sealing step surface are bonded together by sealing glue.

[0009] The utility model has the advantages of practicality, novel structure, low production cost, good air leakage detection effect, improved safety of driving, and fast identification of air leakage of the valve nozzle. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is a disassembled sectional structure schematic view of the utility model.

[0011] Figure 2 It is a sectional structure schematic view of the utility model.

[0012] Figure 3 It is a valve nozzle air leakage state structure schematic view of the utility model. DETAILED DESCRIPTION

[0013] A kind of gas valve cover for measuring gas valve leakage, including gas valve cover body 1, the inner end of gas valve cover body 1 is equipped with opening, opening is equipped with internal thread 101 for thread connection gas valve 2, the outer end of gas valve cover body 1 is equipped with monitoring hole 102 being communicated with opening, monitoring hole 102 is equipped with elastic leak detection piece 3 in sealed arrangement.

[0014] As Figure 1 、 Figure 2 and Figure 3 Indicated, the threaded structure of internal thread 101 is installed on the gas valve 2 of automobile tire, this installation is same as the installation of existing gas valve cover.When gas valve 2 is damaged, the gas leaked can be blown out a distance like blowing balloon, as Figure 3 Indicated, user can judge that gas valve 2 has been damaged according to the feature state.

[0015] The outer wall of gas valve cover body 1 is integrally formed with anti-skid line.Or the outer part of gas valve cover body 1 is also the cross section of regular hexagon, which can prevent slipping and facilitate rotating gas valve cover body 1.

[0016] Monitoring hole 102 is formed with a sealing step surface 103 between the inner wall of gas valve cover body 1, the edge of elastic leak detection piece 3 is integrally formed with sealing ring 301 being matched with sealing step surface 103, the thickness of sealing ring 301 is greater than the thickness of middle part of elastic leak detection piece 3, which is convenient for blowing a bulge when leaking, to judge gas valve 2 leakage.

[0017] Sealing ring 301 and sealing step surface 103 are bonded together with sealing glue, and the sealing effect is better.In addition to the bonding structure, sealing ring 301 can also be squeezed between sealing step surface 103 and gas valve 2 after installing the utility model, which can also realize the installation and fixation of elastic leak detection piece 3.
