Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulators, in particular to a gas pressure regulator. Background Art

[0002] Existing gas pressure regulators are fixed by connecting flanges and bolts. They are generally installed in fixed areas, and most of the pressure regulators are located in unventilated areas. Their surfaces are susceptible to corrosion, which leads to corrosion of the fixing bolts on the pressure regulator, affecting subsequent disassembly of the pressure regulator for maintenance and other operations.

[0003] Therefore, the traditional voltage regulator can be improved so that it can add a protective structure for the fixing bolts on the voltage regulator, thereby preventing the fixing bolts from being corroded by water vapor in the environment and accelerating aging. Utility Model Content

[0004] The purpose of the utility model is to provide a gas pressure regulator in order to solve the above problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A gas pressure regulator includes a body, a flange and bolts. The two flanges of the body are fixed by bolts, and the two flanges are respectively in contact with baffle 1 and baffle 2. Baffle 1 and baffle 2 are respectively provided with slot 1 and slot 2 that contact the corresponding flanges, and slot 1 and slot 2 are respectively provided with groove 1 and groove 2 that accommodate bolts. Baffle 1 and baffle 2 are fixed by a connecting piece to seal and cover the flanges and bolts.

[0007] Preferably, the connecting member includes a bent rod fixed on the baffle plate 1, and the end of the bent rod is connected to the screw sleeve through a thread; a connecting rod is fixed on the baffle plate 2, and the connecting rod is also connected to the screw sleeve through a thread.

[0008] Preferably, a slider is slidably connected to the bent rod, and a clamping rod is fixed to the slider. A clamping groove adapted to the clamping rod is provided on the screw sleeve, and a plurality of clamping grooves are distributed at equal angles on the circumference of the screw sleeve.

[0009] Preferably, a spring is sleeved on the bent rod, and one end of the spring abuts against the bent portion of the bent rod, and the other end abuts against the upper surface of the slider.

[0010] Preferably, an elastic rubber gasket is provided on the portion where the slider abuts against the end of the screw sleeve.

[0011] Preferably, a sealing ring is provided on the portion where the baffle 1 and the baffle 2 abut against each other.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] 1. The present application can protect the flange and the bolts under the shielding protection of baffles 1 and 2, so that the bolts will not come into contact with the water vapor in the environment, and the bolt corrosion phenomenon will occur. By rotating the threaded sleeve, the position of baffles 1 and 2 can be changed, so that baffles 1 and 2 can be brought closer or separated, which is convenient for the installation or removal of baffles 1 and 2.

[0014] 2. In this application, the slider moves under the elastic force of the spring, and the clamping rod at the bottom thereof extends into the clamping groove provided on the screw sleeve, thereby limiting the screw sleeve and making it unable to rotate under force. Therefore, baffle 1 and baffle 2 can stably play a shielding and protective effect on the flange and bolts, which is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] This utility model provides a technical solution, please refer to Figure 1-4 :

[0024] A gas pressure regulator includes a body 1, a flange 2, and bolts 3. The two flanges 2 of the body 1 are fixed by the bolts 3, and the two flanges 2 are in contact with baffles 1 4 and 2 7, respectively. A sealing ring is provided on the abutting portion of baffles 1 4 and 2 7. Baffles 1 4 and 2 7 are respectively provided with slots 1 5 and 2 8 that contact the corresponding flanges 2. Slots 1 5 and 2 8 are respectively provided with grooves 1 6 and 2 9 that accommodate the bolts 3. Baffles 1 4 and 2 7 are fixed by a connector, sealing and shielding the flanges 2 and bolts 3. Under the shielding and protection of baffles 1 4 and 2 7, the flanges 2 and bolts 3 are protected, preventing the bolts 3 from coming into contact with moisture in the environment and corroding the bolts 3.

[0025] Example 2:

[0026] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the connecting member includes a bent rod 10 fixed to baffle 1 4, with a threaded sleeve 15 threadedly connected to the end of the bent rod 10. A connecting rod 14 is fixed to baffle 2 7 and is also threadedly connected to the sleeve 15. By rotating the sleeve 15, the bent rod 10 and the connecting rod 14 can be moved closer to each other, that is, the baffle 1 4 and the baffle 2 7 are moved closer to each other, until the baffle 1 4 and the baffle 2 7 cooperate to cover and protect the flange 2.

[0027] Example 3:

[0028] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, a slider 11 is slidably connected to the curved rod 10, and a clamping rod 12 is fixed to the slider 11. A screw sleeve 15 is provided with a clamping groove 16 that matches the clamping rod 12, and multiple clamping grooves 16 are distributed at equal angles around the circumference of the screw sleeve 15. A spring 13 is sleeved on the curved rod 10, with one end of the spring 13 abutting the bend of the curved rod 10 and the other end abutting the upper surface of the slider 11. An elastic rubber gasket is provided on the portion where the slider 11 abuts the end of the screw sleeve 15.

[0029] In summary, the present embodiment provides a method of abutting baffle 1 4 and baffle 2 7 against the corresponding flange 2, and aligning groove 1 6 and groove 2 9 with the bolt 3. The slider 11 can then be pushed upward to move the slider 11 away from the screw sleeve 15. The screw sleeve 15 is rotated so that the screw sleeve 15 is threadedly connected to the bent rod 10 and the connecting rod 14 until baffle 1 4 and baffle 2 7 clamp the flange 2, and groove 1 6 and groove 2 9 are sleeved on the bolt 3. The thrust on the slider 11 is released, and under the elastic force of the spring 13, the slider 11 is moved downward until the clamping rod 12 at the end of the slider 11 extends into the corresponding clamping groove 16 on the screw sleeve 15, thus completing the installation of baffle 1 4 and baffle 2 7.

[0030] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
