Description

Spring type metal hose

Technical Field

The utility model relates to a metal collapsible tube technical field, especially a spring metal collapsible tube.

Background

The metal hose is an important component in the connecting pipeline of modern industrial equipment, and the metal hose is mainly composed of three major parts, namely a corrugated pipe, a net sleeve and a joint. The corrugated pipe is the body of the metal hose, plays a flexible role, the net cover plays a reinforcing and shielding role, the joint plays a connecting role, in the prior art, due to long-time use, an oxide film is formed on the surface after the metal reacts with oxygen in the atmosphere, and the protection is only a thin film. If the protective layer is destroyed, the steel below starts to be rusted, and the metal hose is easy to be excessively bent in the using process, so that the braided net outside the pipe is abraded, high pressure burst is caused, and secondly, because the clean fuel is common, more and more burners need to be used with the metal hose, so that the single joint cannot meet the existing requirement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's shortcoming, provide a spring metal collapsible tube.

The purpose of the utility model is realized through the following technical scheme: the utility model provides a spring type metal hose, includes hose body, joint, spring, three-way pipe and protective sheath, the hose body includes bellows and woven mesh, woven mesh wraps up on the outer wall of bellows, the both ends of hose body all are connected with the joint, woven mesh's both ends still all are overlapped and are equipped with the spring, the one end of spring is fixed on the joint, and the other end of spring is the free end, the one end of three-way pipe is installed on a joint, woven mesh sheathes in still to be equipped with the protective sheath, and this protective sheath is located between two springs.

Preferably, each spring all includes one section dense wave spring and one section weak wave spring, dense wave spring and weak wave spring interconnect, and dense wave spring sets up near joint department.

Preferably, one end of the three-way pipe is in threaded connection with a joint, and valves are arranged at the other two ends of the three-way pipe.

Preferably, the protective sleeve is provided with a clamping opening along the length direction, and the protective sleeve is made of 304 stainless steel, a steel wire explosion-proof net and a PVC rubber layer inner tube which are made of integrated materials.

The utility model has the advantages of it is following:

firstly, connect the natural gas pipeline through the joint, then the gas burner that needs to fill natural gas is connected with metal collapsible tube through the three-way pipe of the other end, and the design of connection end screw thread makes its leakproofness better, is difficult for taking place gas leakage phenomenon when using, has improved the security, thereby the detachable protective sheath can prevent that metal collapsible tube from causing oxide corrosion metal collapsible tube with external oxygen contact, extension metal collapsible tube's life.

Secondly, the dense wave spring that designs on the hose body can effectually prevent to press from both sides when installing and hinder the palm, and the minimum bend radius of control hose can be installed in the design of rare wave spring, makes metal collapsible tube can not excessively bend in narrow and small space, causes the mesh grid wearing and tearing outside the pipe, causes the high pressure to burst.

Thirdly, the valve handle on the three-way pipe is rotated to control the on-off of the valve, so that the single use or the joint operation of various natural gas appliances in a kitchen can be met.

Drawings

Fig. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic structural view of the hose body of the present invention.

In the figure: the flexible pipe comprises a flexible pipe body 1, a corrugated pipe 11, a woven net 12, a joint 2, a spring 3, a dense wave spring 31, a thin wave spring 32, a three-way pipe 4, a valve 41 and a protective sleeve 5.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 2, a spring type metal hose comprises a hose body 1, a connector 2, a spring 3, a three-way pipe 4 and a protective sleeve 5, wherein the hose body 1 comprises a corrugated pipe 11 and a woven net cover 12, the woven net cover 12 is wrapped on the outer wall of the corrugated pipe 11, the two ends of the hose body 1 are both connected with the connector 2, the spring 3 is further sleeved at the two ends of the woven net cover 12, one end of the spring 3 is fixed on the connector 2, the other end of the spring 3 is a free end, one end of the three-way pipe 4 is installed on one connector 2, the protective sleeve 5 is further sleeved on the woven net cover 12, and the protective sleeve 5 is located between the two springs 3.

Specifically, every spring 3 all includes one section dense ripples spring 31 and one section rare ripples spring 32, dense ripples spring 31 and rare ripples spring 32 interconnect, and dense ripples spring 31 is close to joint 2 department and sets up, the palm is hindered to the clamp when close ripples spring 31 of design on the hose body 1 can effectually prevent the installation, the minimum bend radius of control hose when the design of rare ripples spring 32 can be installed, make metal collapsible tube can not excessively be crooked in narrow and small space, cause the mesh grid wearing and tearing outside the pipe, cause the high pressure to burst.

Specifically, one end of the three-way pipe 4 is in threaded connection with the connector 2, valves 41 are arranged at the other two ends of the three-way pipe 4, the on-off of the valves 41 can be controlled by rotating the handles of the valves 41 on the three-way pipe 4, and the single use or the joint operation of multiple natural gas appliances in a kitchen can be met.

Specifically, protective sheath 5 has seted up the block mouth along its length direction, and protective sheath 5 is made for 304 stainless steel, explosion-proof net of steel wire, PVC rubber layer inner tube integration material, thereby detachable protective sheath 5 can prevent that metal collapsible tube and external oxygen from contacting and causing oxide corrosion metal collapsible tube, extension metal collapsible tube's life.

The working process of the utility model is as follows: firstly, a natural gas pipeline is connected through a connector 2, so that natural gas enters a metal hose, then natural gas is filled into a gas appliance connected with a three-way pipe 4 by rotating a gas valve handle, in the installation process, the connection of the end screw thread design, make its leakproofness better, difficult to take place the gas leakage phenomenon when using, improved the security, the spring 3 at hose body 1 both ends can prevent effectively that the installation from pressing from both sides the injury palm and make metal collapsible tube in narrow and small space excessively crooked, cause the mesh grid wearing and tearing outside the pipe, cause the high pressure to burst, the detachable protective sheath 5 of the middle end of hose body 1 can prevent metal collapsible tube and external oxygen contact and cause the oxide corrosion metal collapsible tube, prolong metal collapsible tube's life, meanwhile, the matching of the three-way pipe 4 and the valve 41 can meet the single use or the common operation of various appliances using natural gas in a kitchen.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
