[0024] See also Figure 1-Figure 4 As shown, an embodiment of the utility model is a liquid gas pressure reducing and metering skid-mounted device, comprising a skid-mounted frame 1, in which a plurality of groups of connecting plates 103 are fixedly installed, and limit plates 104 are fixedly installed on the upper and lower surfaces of the upper and lower opposite connecting plates 103, and the limit plates 104 are arc-shaped, and liquid gas tanks 3 are placed between the limit plates 104 on every two groups of connecting plates 103, and six liquid gas tanks 3 are provided, and a protective box 4 is fixedly installed at one end of the skid-mounted frame 1, and an outlet at one end of the liquid gas tank 3 penetrates into the protective box 4, and is connected to a pressure reducing valve 301, and one end of the pressure reducing valve 301 is connected to a connecting pipe 302, and one end of the connecting pipe 302 is respectively connected to a flow meter 303 and a safety valve 304.

[0025] A bracket plate 101 is fixedly mounted on the upper surface of the skid-mounted frame 1 , and a contact mechanism 2 is provided on the lower surface of the bracket plate 101 . The contact mechanism 2 can contact the outer surfaces of the six liquid gas tanks 3 .

[0026] A box door 401 is rotatably mounted at one end of the protection box 4, and a lock buckle 402 is rotatably mounted at one end of the box door 401. The lock buckle 402 can be buckled on one end of a buckle plate 403, and the buckle plate 403 is fixedly mounted on one end of another set of box doors 401.

[0027] Anti-tilt top plates 102 are fixedly mounted on both ends of the skid-mounted frame 1 .

[0028] Through the design of the contact mechanism 2, the anti-tilt top plate 102 and the liquid gas tank 3, each group of liquid gas tanks 3 is filled in the limit plate 104 on the connecting plate 103, each group of liquid gas tanks 3 is separated, and at the same time, a limiting effect is applied to them to avoid collisions between liquid gas tanks 3 and liquid gas tanks 3. At the same time, the contact mechanism 2 can be inflated to make it contact the outer surface of the liquid gas tank 3 again to increase the friction between the liquid gas tank 3 and the liquid gas tank 3, and a rotation limiting force is applied to the liquid gas tank 3 to avoid the liquid gas tank 3 from rotating due to vibration during the movement of the skid-mounted frame 1.

[0029] The flow meter 303, the safety valve 304 and the pressure reducing valve 301 at one end of the liquid gas tank 3 are installed in the protective box 4. When not in use, the two sets of box doors 401 can be locked by the lock 402 and the buckle plate 403 to protect the pipelines therein and prevent them from being exposed to the outside.

[0030] The anti-tilt top plates 102 installed on both sides of the skid-mounted frame 1 increase the anti-tilt performance of the skid-mounted frame 1.

[0031] like Figure 5 As shown, the top contact mechanism 2 includes an inflatable cushion 201 , and an inflatable port 202 on the upper surface of the inflatable cushion 201 penetrates and is connected to the upper surface of the bracket plate 101 . The inflatable port 202 can be sealed and blocked by a plug 203 , and the plug 203 is fixedly connected to the upper surface of the bracket plate 101 .

[0032] The inflatable cushion 201 is made of polyurethane polymer material.

[0033] The inflatable cushion 201 has six sides, and each side can contact the outer surface of the liquid gas tank 3 .

[0034] Through the inflatable cushion 201 and the plug 203, the inflatable cushion 201 can be expanded by inflating air into the inflation port 202, and the curved surface of the inflated and expanded inflatable cushion 201 will fit on the surface of the liquid gas tank 3, thereby increasing the friction between the liquid gas tank 3 and the liquid gas tank 3. At the same time, the limiting effect of the limiting plate 104 can prevent the liquid gas tank 3 from self-collision and rotation due to vibration force during the movement of the skid-mounted frame 1.

[0035] According to the above technical scheme, the working principle of the embodiment of the utility model is as follows: each liquid gas tank 3 is filled in the limiting plate 104 on the connecting plate 103, which separates each group of liquid gas tanks 3 and can also apply a limiting effect thereto, thereby avoiding collisions between liquid gas tanks 3 and liquid gas tanks 3, and at the same time, air can be inflated into the inflation port 202 to expand the inflatable cushion 201, and the arc surface of the inflated and expanded inflatable cushion 201 will fit on the surface of the liquid gas tank 3, thereby increasing the friction between the liquid gas tank 3.

[0036] When using, you need to first check whether the inlet and outlet pipe connections of the pressure reducing valve 301 are tight and leak-free, then slowly open the shut-off valve in front of the pressure reducing valve 301, observe the working condition of the pressure reducing valve 301, and ensure that the outlet pressure of the pressure reducing valve 301 is stable. You can adjust the outlet pressure through the regulating mechanism of the pressure reducing valve 301 as needed. After starting, you can observe the indication of the flow meter to ensure that the flow meter is working normally and the displayed data is accurate.

[0037] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
