Description

Technical Field

[0001] The utility model relates to a pressure reducing valve in a pipeline valve, in particular to a pressure reducing valve with an adjustable pressure gauge angle. Background Art

[0002] The pressure reducing valve is a common valve in the piping system, which can be widely used in urban water supply networks or heating piping systems, etc. It can reduce the pressure in the piping system and keep it within a constant pressure range. At the same time, in order to facilitate the observation of pressure changes in the piping system, a pressure gauge is usually configured on the pressure reducing valve. The pressure gauge installation method of the traditional pressure reducing valve is mainly to set an internal threaded mounting hole at the outlet end of the main body of the pressure reducing valve, and an external threaded joint is provided at the end of the pressure gauge. Therefore, the pressure gauge can be assembled with the internal threaded mounting hole on the main body by screwing the external threaded joint. However, there is an obvious problem with this assembly method, that is, after the pressure gauge is tightened on the main body and assembled, the direction of the pressure gauge is randomly fixed, which will bring great inconvenience to the observation and reading of the pressure gauge. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a pressure reducing valve with adjustable pressure gauge angle, which can adjust the use angle through 360-degree free sealing rotation of the pressure gauge on the main body, thereby facilitating observation and reading of the pressure gauge.

[0004] The technical problem of the utility model is achieved through the following technical solutions:

[0005] A pressure reducing valve with an adjustable pressure gauge angle comprises a main body and a pressure gauge. The main body is provided with a mounting hole. The pressure reducing valve also comprises a connecting pipe. The pressure gauge is sealingly connected to one end of the connecting pipe. The other end of the connecting pipe is sealingly inserted in the mounting hole and forms an axial stop. The pressure gauge forms a 360-degree free sealing rotation relative to the mounting hole through the connecting pipe.

[0006] The connecting pipe is composed of an insert pipe and a connecting pipe which are respectively located at two ends and are coaxially arranged.

[0007] The end of the insert is provided with an umbrella-shaped buckle, and a corresponding annular groove is provided on the hole wall of the mounting hole. The insert is inserted into the mounting hole, and the umbrella-shaped buckle is fitted in the annular groove to form axial locking and 360-degree free rotation of the insert in the mounting hole.

[0008] A sealing ring is arranged between the insert pipe and the mounting hole, which enables the insert pipe to rotate freely and sealedly within the mounting hole at 360 degrees.

[0009] An annular embedding groove is arranged on the outer circumferential surface of the insert pipe, and the sealing ring is embedded and fixed in the embedding groove and simultaneously forms a dynamic sealing contact with the hole wall of the installation hole.

[0010] The pressure gauge is connected to the connecting pipe via a tightening structure of internal and external threads, and a sealing gasket is arranged between the pressure gauge and the connecting pipe to form a connection seal.

[0011] The inserting pipe and the connecting pipe are both cylindrical pipes, the pipe diameter of the inserting pipe is smaller than the pipe diameter of the connecting pipe, and an outer shoulder is formed at the junction of the inserting pipe and the connecting pipe.

[0012] The insert pipe is inserted into the mounting hole to form an axial stop, and the outer shoulder contacts the end surface of the mounting hole.

[0013] The outer circumferential surface of the connecting pipe is provided with anti-skid patterns processed by knurling technology.

[0014] The outer surface of the main body is provided with a mounting tube extending in a continuous manner, and the mounting hole penetrates the mounting tube along the axial direction and is connected to the outlet end of the main body.

[0015] Compared with the prior art, the utility model mainly adds a connecting pipe to the main body of the pressure reducing valve, and seals the pressure gauge to one end of the connecting pipe, while the other end of the connecting pipe is seal-inserted in the mounting hole and forms an axial stop; in this way, the pressure gauge can form a 360-degree free sealed rotation relative to the mounting hole through the connecting pipe, that is, the pressure gauge can perform a 360-degree free sealed rotation on the main body to adjust the use angle; obviously, the improved structure effectively solves the problem that the traditional pressure gauge is often randomly fixed in direction after being tightened on the main body and assembled, thereby greatly facilitating the observation and reading of the pressure gauge, and also has the advantages of simple structure and easy assembly.

[0020] The embodiments of the present invention will be described in detail below according to the above-mentioned drawings.

[0022] A pressure reducing valve with an adjustable pressure gauge angle, such as Figure 1 As shown, it mainly relates to a pipeline valve suitable for urban tap water pipe networks or heating pipe systems, etc., and its structure includes a main body 1, a connecting pipe 3 and a pressure gauge 2, etc.

[0023] The main body 1 is provided with a mounting hole 12, as shown in FIG. Figure 2 As shown, a mounting tube 13 extending in a continuous manner is provided on the outer surface of the main body 1 , and a mounting hole 12 penetrates the mounting tube 13 along the axial direction and communicates with the outlet end 11 of the main body 1 .

[0024] The connecting pipe 3 is composed of an insert pipe 31 and a connecting pipe 32 which are coaxially arranged at both ends. The insert pipe 31 and the connecting pipe 32 are both cylindrical pipes, and the diameter of the insert pipe 31 is smaller than the diameter of the connecting pipe 32. An outer shoulder 33 is formed at the junction of the insert pipe 31 and the connecting pipe 32.

[0025] The end of the insert tube 31 is provided with an umbrella-shaped buckle 311, which is a structure similar to a barb, and a circle of annular groove 14 is correspondingly provided on the hole wall of the mounting hole 12. The insert tube 31 is directly inserted into the mounting hole 12, and the umbrella-shaped buckle 311 is just fitted in the annular groove 14. Therefore, the insert tube 31 can form an axial stop through the mutually fitted umbrella-shaped buckle 311 and the annular groove 14, that is, prevent the insert tube 31 from axially outwardly falling out of the mounting hole 12, and can also enable the insert tube 31 to form 360-degree free rotation in the mounting hole 12.

[0026] Moreover, the insert tube 31 is inserted into the mounting hole 12 to form an axial stop, and the outer shoulder 33 is also in contact with the end surface of the mounting hole 12, playing a role of inserting and limiting.

[0027] A sealing ring 5 is provided between the insert tube 31 and the mounting hole 12. Specifically, an annular embedding groove 312 is provided on the outer circumferential surface of the insert tube 31, and the sealing ring 5 is embedded and fixed in the embedding groove 312. Therefore, when the insert tube 31 is inserted into the mounting hole 12, the sealing ring 5 also forms a dynamic sealing contact with the hole wall of the mounting hole 12. Therefore, the insert tube 31 can achieve 360-degree free sealing rotation in the mounting hole 12.

[0028] The pressure gauge 2 is connected to the connecting pipe 32 via an internal and external threaded tightening structure. Specifically, the pressure gauge 2 is threadedly tightened with the internal threaded hole 321 of the connecting pipe 32 via an external threaded joint, and a sealing gasket 4 is also provided between the pressure gauge 2 and the connecting pipe 32 to form a connection seal between the two.

[0029] In this way, the pressure gauge 2 can form a 360-degree free sealed rotation relative to the mounting hole 12 through the connecting pipe 3, that is, the pressure gauge 2 can perform a 360-degree free sealed rotation on the main body 1 to adjust the use angle, and the outer circumferential surface of the connecting pipe 32 is also provided with anti-slip patterns processed by knurling process to facilitate the quick installation of the pressure gauge 2.

[0030] Obviously, the improved structure effectively solves the problem that the traditional pressure gauge 2 is often randomly fixed in direction after being tightened on the main body 1 and assembled, thereby greatly facilitating the observation and reading of the pressure gauge 2, and also has the advantages of simple structure and easy assembly.

[0031] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
