Abstract
The utility model discloses a screw jointed acoustic pipe, which comprises a pipe body. The pipe body comprises a plurality of secondary pipes connected in sequence through connectors, wherein the connectors comprise a primary connector and a secondary connector which are mutually matched; the outer wall of the secondary connector is provided with an external screw thread; the bottom of the external screw thread is provided with an annular slot for containing a sealing ring; the inner wall of the primary connector is provided with an internal screw thread which is matched with the external screw thread; and the inner wall of an end part sleeved on one end of the secondary connector adopts a flared conical surface which is tightly contacted with the sealing ring when the conical surface is connected to the secondary connector. The screw jointed acoustic pipe is connected through mutually matched primary and secondary connectors, and the bottom of the secondary connector is provided with the sealing ring while the end port of the primary connector is provided with the conical surface matched with the sealing ring. Therefore, the screw jointed acoustic pipe of the utility model has the advantages of good sealing effect, simple structure, and convenient manufacturing.
Description
Technical field
The utility model relates to the building pipe field, relates in particular to a kind of sound detecting pipe that is threaded.
Background technology
In the work progress of construction work, the normal integrality that adopts supersonic sounding to check pile foundation, supersonic sounding needed before the concrete spouting of pile foundation, in advance sound detecting pipe is fixed on the cage, penetration concrete then, thereafter again by emission between sound detecting pipe and reception sound wave, the parameters,acoustic that reflects with sound wave changes the purpose that reaches the inspection pile body integrity.
At present, sound detecting pipe is according to unusual be threaded sound detecting pipe and the plug-type sound detecting pipe that is connected of being divided into of connected mode.The sound detecting pipe that is threaded is when making sound detecting pipe its two ends to be manufactured the helicitic texture that can cooperatively interact, general employing one end is an external thread structure, the other end is a female thread structure, and two sound detecting pipes interconnect by internal and external threads, and this sound detecting pipe sealing effectiveness is not good.Plug-type connection sound detecting pipe then is to utilize a plurality of sealing rings are set in body, an end of a body is inserted in another root body sealing ring, thereby finishes interfixing of many sound detecting pipes; This sound detecting pipe is installed inconvenience, and sealing effectiveness is bad.
Summary of the invention
The utility model provides a kind of sound detecting pipe that is threaded of easy for installation, good airproof performance.
A kind of sound detecting pipe that is threaded, comprise body, described body is made up of by the child pipe that joint connects successively plurality of sections, described joint is made up of the sub-joint and the female joint that cooperatively interact, and described sub-joint outer wall is provided with external screw thread, and externally threaded bottom has the cannelure that holds sealing ring, described female joint inwall is provided with the internal thread that matches with external screw thread, an end end inwall that is enclosed within on the sub-joint is the conical surface of enlarging, and when being connected with sub-joint, this conical surface and sealing ring closely paste and touch.
Described sub-joint and female joint are fixing with the two ends end face welding of sub-pipe respectively, have effectively increased the length of sound detecting pipe.
Described body two ends are provided with seal cover, prevent that foreign matter from entering sound detecting pipe.
Described seal cover is placed in the end of body, and is easy for installation.
The end face welding of described seal cover and body is fixing, increases body length.
Described external thread length is 18～20mm, and internal thread length is 21～23.5mm.
The utility model is threaded sound detecting pipe by the primary and secondary joint connection that matches, and sub-joint bottom is provided with sealing ring, and the female joint port part is provided with the conical surface that is sealed and matched with sealing ring, good sealing effect, and simple in structure, easily manufactured.

The specific embodiment
As shown in Figure 1, a kind of sound detecting pipe comprises body, and body is made up of some child pipes 1 that connect successively by joint, and joint comprises sub-joint 2 and the female joint 3 that cooperatively interacts.Except that the two root pipes at two ends, middle child pipe two ends are respectively equipped with sub-joint 2 and female joint 3.The two root Guan Yiduan at two ends are provided with sub-joint 2 or female joint 3, are connected sealed lid 5 sealings of the other end with adjacent child pipe.
The mode of seal cover 5 sealings is varied, and as shown in Figure 3, seal cover 5 is placed in the end of body, and as shown in Figure 4, the welding of the end face of seal cover and body forms welding circle 7.The connected mode of sub-joint 2 or female joint 3 and sub-pipe can be varied, as socket etc., also can select mode as shown in Figure 1, sub-joint 2 and female joint 3 are fixing with the end face welding of sub-pipe, so not only can not reduce the length of body, and can increase body length.
The outer wall of sub-joint 2 is provided with external screw thread, and female joint 3 is provided with the internal thread that cooperates with external screw thread.The external screw thread bottom is provided with cannelure, and cannelure is built-in with sealing ring 4, and the end end inwall that female joint 3 is enclosed within on the sub-joint 2 is the conical surface 6 of enlarging, and when sub-joint 2 was connected with female joint 3, the conical surface and sealing ring 4 closely cooperated, and reached to be tightly connected.For the sealing effectiveness that guarantees necessarily to reach certain, external thread length is set to 18～20mm, and internal thread length is 21～23.5mm, guarantees that sealing ring 4 can cooperate with conical surface seal.
