[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0028] A pressure regulating, metering and odorizing skid, comprising:

[0029] Odorizing skid body connecting pipe 1;

[0030] A sealing sleeve 2, which is sleeved on the outer surface of the odorizing skid body connecting pipe 1;

[0031] Sealing assembly, the sealing assembly is provided with two groups, each group of sealing assemblies includes a hydraulic groove 3, a propulsion groove 4, a pressure block 5, a spring groove 6, an insertion block 7, a return spring 8 and a sealing block 9. Two return springs 8 are provided. The hydraulic groove 3 is opened on the circumferential inner wall of the sealing sleeve 2, the propulsion groove 4 is opened on the circumferential inner wall of the sealing sleeve 2 and is connected with the hydraulic groove 3. The pressure block 5 is slidably connected in the propulsion groove 4, the spring groove 6 is opened on the circumferential inner wall of the hydraulic groove 3, the insertion block 7 is fixedly connected to one side end of the pressure block 5 and slides in the spring groove 6, the two return springs 8 are fixedly connected to one side inner wall of the spring groove 6 and one side end of the pressure block 5, and the sealing block 9 slides on one side inner wall of the hydraulic groove 3.

[0032] In a specific embodiment of the utility model, the sealing sleeve 2 is a combination of two half shells. The sealing sleeve 2 replaces the flange to fix the two ends of the odorizing pry body connecting pipe 1 of the odorizing pry. The sealing sleeve 2 is sleeved on the outside of the odorizing pry body connecting pipe 1. The thrust of the return spring 8 causes the outer end of the pressure block 5 to be arranged in the sealing sleeve 2. The sealing block 9 is arranged in the hydraulic groove 3 and is parallel to the inner wall of the sealing sleeve 2. Hydraulic oil is arranged in the hydraulic groove 3, and the hydraulic groove 3 is closed by the pressure block 5 and the sealing block 9 to form a sealed space. When the two odorizing pry body connecting pipes 1 are connected, one side of the odorizing pry body connecting pipe 1 is inserted into the sealing sleeve 2. The outer surface of the odorizing pry body connecting pipe 1 squeezes the pressure block 5 to push the pressure block 5 into the hydraulic groove 3 and push the return spring 8 to contract until the return spring 8 is removed from the sealing sleeve 2. The pressurizing block 5 can be reset. As the pressurizing block 5 slides and squeezes the space in the hydraulic groove 3 to reduce and increase the hydraulic pressure in the hydraulic groove 3, the high hydraulic pressure pushes the sealing block 9 outward until the odorizing skid body connecting pipe 1 is completely inserted into the sealing sleeve 2. The odorizing skid body connecting pipe 1 squeezes the sealing block 9 back to its original position to maintain the high hydraulic pressure in the hydraulic groove 3. The hydraulic pressure forms a thrust to push the sealing block 9 to fit tightly against one side end of the odorizing skid body connecting pipe 1, thereby sealing the gap at the connection between the odorizing skid body connecting pipe 1 and the sealing sleeve 2. The hydraulic strength in the hydraulic groove 3 is improved by squeezing the space in the hydraulic groove 3 when the odorizing skid body connecting pipe 1 is installed, and the sealing block 9 is pushed by the hydraulic strength to seal the odorizing skid body connecting pipe 1 and the sealing sleeve 2 to improve the sealing strength and prevent natural gas from leaking.

[0033] For details, please refer to Figure 1-Figure 4 A limiting slide groove 10 is provided on one inner wall of the hydraulic groove 3 , and a limiting slide rod 11 is fixedly connected to one end of the sealing block 9 , and the limiting slide rod 11 slides in the limiting slide groove 10 .

[0034] In this embodiment: a limiting slide groove 10 is opened at the rear end of the sealing block 9, and a limiting slide rod 11 connected to the sealing block 9 slides in the limiting slide groove 10 to limit the sliding direction of the sealing block 9, so that the sealing block 9 can only slide horizontally and fit the outer surface of the sealing block 9.

[0035] For details, please refer to Figure 1-Figure 4 A fixed block 12 is provided on the circumferential surface of the odorizing skid body connecting pipe 1.

[0036] In this embodiment: the fixed clamping block 12 is arranged on the outer surface of the odorizing pry body connecting tube 1 to clamp the odorizing pry body connecting tube 1. The odorizing pry body connecting tube 1 is made of polyethylene and has a certain toughness. After the fixed clamping block 12 is squeezed and contracted until the odorizing pry body connecting tube 1 is completely inserted into the sealing sleeve 2, the fixed clamping block 12 clamps the inner wall of the sealing sleeve 2 so that the odorizing pry body connecting tube 1 can no longer be pulled out of the sealing sleeve 2 to complete the fixation of the odorizing pry body connecting tube 1 and the sealing sleeve 2.

[0037] For details, please refer to Figure 1-Figure 4 A pressure gauge 13 is provided in the connecting pipe 1 of the odorizing skid body, and the pressure gauge 13 is provided at one side end of the sealing sleeve 2.

[0038] In this embodiment, the pressure gauge 13 is arranged at one end of the sealing sleeve 2 to measure the natural gas pressure in the odorizing skid body connecting pipe 1 and compare the pressure in the pipe to detect whether the natural gas is leaking.

[0039] For details, please refer to Figure 1-Figure 4 A fixing plate 14 is provided on the outer surface of the sealing sleeve 2 , and a plurality of threaded holes 15 are formed on one side end of the fixing plate 14 .

[0040] In this embodiment: the fixing plate 14 is arranged on one side of the two halves of the sealing sleeve 2, and the side ends of the fixing plate 14 are provided with threaded holes 15 for installing bolts to fix the two halves of the sealing sleeve 2. When it is necessary to remove the odorizing pry body connecting tube 1 and the sealing sleeve 2, the fixing bolts are removed, and then the sealing sleeves 2 on both sides are separated to separate the odorizing pry body connecting tube 1 and the sealing sleeve 2.

[0041] For details, please refer to Figure 1-Figure 4 A guide plate 16 is provided on the circumferential inner wall of the sealing sleeve 2, and the guide plate 16 is arc-shaped.

[0042] In this embodiment, the guide plate 16 is arranged in the middle of the sealing sleeve 2 and is arc-shaped. After the natural gas flows into the sealing sleeve 2, it is guided by the arc-shaped guide plate 16 to change the flow direction of the natural gas and avoid convection.

[0043] It should be noted that the pressure gauge 13 used in the present invention is a prior art and will not be described in detail here.

[0044] The working principle and use process of the utility model are as follows: the sealing sleeve 2 is a combination of two half shells, and the sealing sleeve 2 replaces the flange to fix the two ends of the odorizing pry body connecting pipe 1 of the odorizing pry, and the sealing sleeve 2 is sleeved on the outside of the odorizing pry body connecting pipe 1. The thrust of the reset spring 8 makes the outer end of the pressure block 5 be arranged in the sealing sleeve 2, and the sealing block 9 is arranged in the hydraulic groove 3 and parallel to the inner wall of the sealing sleeve 2. Hydraulic oil is arranged in the hydraulic groove 3, and the hydraulic groove 3 is closed by the pressure block 5 and the sealing block 9 to form a sealed space. When the two odorizing pry body connecting pipes 1 are connected, one side of the odorizing pry body connecting pipe 1 is inserted into the sealing sleeve 2, and the outer surface of the odorizing pry body connecting pipe 1 squeezes the pressure block 5 to push the pressure block 5 into the hydraulic groove 3, and pushes the reset spring 8 to contract until the reset spring 8 is removed from the sealing sleeve 2. 8 can reset the pressurizing block 5. As the pressurizing block 5 slides and squeezes the space in the hydraulic groove 3 to reduce the hydraulic pressure in the hydraulic groove 3, the high hydraulic pressure pushes the sealing block 9 outward until the odorizing skid body connecting pipe 1 is completely inserted into the sealing sleeve 2. The odorizing skid body connecting pipe 1 squeezes the sealing block 9 back to its original position to maintain the high hydraulic pressure in the hydraulic groove 3. The hydraulic pressure forms a thrust to push the sealing block 9 to fit closely to one side end of the odorizing skid body connecting pipe 1, thereby sealing the gap at the connection between the odorizing skid body connecting pipe 1 and the sealing sleeve 2. The hydraulic strength in the hydraulic groove 3 is improved by squeezing the space in the hydraulic groove 3 when the odorizing skid body connecting pipe 1 is installed, and the sealing block 9 is pushed by the hydraulic strength to seal the odorizing skid body connecting pipe 1 and the sealing sleeve 2, thereby improving the sealing strength and preventing natural gas from leaking.
