[0007] Preferably, an installation interface is provided on one side of the support sleeve main body, a valve installation port is provided on the valve, and the installation interface is connected to the valve installation port.

[0008] Preferably, a second channel is provided inside the positioning support sleeve, and the check valve is installed in the second channel. On the other side of the support sleeve body, a positioning sleeve is further provided, and a third channel communicating with the second channel is provided inside the positioning sleeve.

[0009] Preferably, an anti-theft cover is installed at the end of the positioning sleeve. The anti-theft cover has an anti-theft cover body in the shape of a sphere, and the anti-theft cover body is used to block the grease injection channel along the direction from the first channel to the third channel.

[0010] Preferably, the diameter of the positioning sleeve is smaller than the inner diameter of the second mounting hole, so that there is an installation gap between the positioning sleeve and the second mounting hole; an L-shaped mounting portion is provided on the outer periphery of the anti-theft cover body, and an adjustment gasket is provided between the mounting portion and the end face of the positioning sleeve. One side of the mounting portion is sleeved on the end of the positioning sleeve and is relatively fixed to the positioning sleeve.

[0011] Preferably, an annular channel is provided at the end of the third channel, and there is a flow gap between the annular channel and the anti-theft cover body.

[0012] Preferably, a plurality of fifth channels are provided on the anti-theft cover body, the fifth channels are arranged close to the inner peripheral surface of the third channel, and the central axis of the fifth channels intersects with the center of the sphere of the anti-theft cover body.

[0013] An assembly method of an anti-theft grease injection valve, the assembly method includes the following steps: S1: Assemble the check valve into the second channel of the positioning support sleeve; S2: Install the sealing gasket in the installation groove on the positioning boss, and sleeve the anti-theft cover on the end of the positioning sleeve; S3: Assemble the positioning support sleeve into the second mounting hole of the anti-theft valve body; S4: Positioned by the positioning support sleeve, assemble the installation interface into the valve installation port, and then weld the anti-theft valve body on the valve; S5: Assemble the grease injection valve into the first mounting hole of the anti-theft valve body.

[0014] Compared with the prior art, an anti-theft grease injection valve and its assembly method provided by the present invention have the following beneficial technical effects: 1. In the anti-theft valve body of the present invention, a first mounting hole and a second mounting hole are respectively opened along the radial direction and the axial direction, and the first mounting hole and the second mounting hole are communicated through a first channel. A grease injection valve and a positioning support sleeve are respectively installed in the first mounting hole and the second mounting hole. A second channel and a third channel are axially opened in the positioning support sleeve, and a check valve is installed in the second channel. The above settings make the grease injection channel in the anti-theft grease injection valve arranged at a right angle. Compared with the existing grease injection valve, it is not easy to remove the check valve and the grease injection valve at the same time, reducing the risk of pipeline oil theft.

[0015] 2. An anti-theft cover is installed at the end of the positioning sleeve. The anti-theft cover has a spherical anti-theft cover body, and the anti-theft cover body can block the grease injection channel along the direction from the first channel to the third channel. In some cases, the anti-theft cover body can guide some theft tools to move in the direction opposite to the check valve, thus preventing the check valve from being directly opened by theft tools and reducing the risk of stealing oil.

[0016] 3. An annular channel is opened at the end of the third channel, and a number of fourth channels are evenly opened in the circumferential direction of the installation part, so that the grease can be smoothly injected into the valve interior through the fourth channels and the annular channel. Since the positions of the fourth channels and the flow gap are close to the outer periphery of the anti-theft cover, and the fourth channels and the flow gap only partially overlap axially, the grease injection channel designed in this way can increase the operation difficulty of directly opening the check valve with theft tools, further reducing the risk of stealing oil.

[0017] 4. An adjusting gasket is also arranged between the installation part and the positioning sleeve of the present invention. The adjusting gasket can be used to adjust the axial distance between the fourth channel and the flow gap. By increasing the thickness of the adjusting gasket, the axial distance between the fourth channel and the flow gap can be increased, so that the grease can be more efficiently injected into the valve through the fourth channel and the flow gap.

[0018] 5. A number of fifth channels are opened on the anti-theft cover body of the present invention, which can improve the grease injection efficiency of the anti-theft grease injection valve; and the fifth channels are arranged close to the inner peripheral surface of the third channel, and the central axis of the fifth channel intersects with the center of the sphere of the anti-theft cover body. Such a setting can prevent theft tools from opening the check valve and reduce the risk of stealing oil. Description of the Drawings

[0026] See the attached Figure 1 - attached Figure 6 As shown, the present invention provides an anti-theft grease injection valve, which is installed on the valve 1. The anti-theft grease injection valve includes: an anti-theft valve body 4, a positioning support sleeve 5 is installed axially inside the anti-theft valve body 4, a check valve 3 is installed inside the positioning support sleeve 5, and a grease injection valve 2 is installed radially on the outer side of one end of the anti-theft valve body 4, so that the grease injection channel formed by the grease injection valve 2, the anti-theft valve body 4 and the positioning support sleeve 5 is set at a right angle. After the anti-theft grease injection valve is installed on the valve 1, it can prevent the check valve 3 from being disassembled by lawbreakers, greatly reducing the risk of pipeline oil theft.

[0027] Preferably, the anti-theft valve body 4 has a main body portion 41. One end of the main body portion 41 is provided with a mounting table 42, a first mounting hole 43 is opened radially along the mounting table 42, the grease injection valve 2 is connected to the first mounting hole 43, a second mounting hole 45 is opened axially along the main body portion 41, and the positioning support sleeve 5 is connected to the second mounting hole 45. Between the first mounting hole 43 and the second mounting hole 45, a first channel 44 is also opened axially along the main body portion 41, and the first mounting hole 43 and the second mounting hole 45 are communicated through the first channel 44.

[0028] Preferably, the positioning support sleeve 5 has a support sleeve main body 51, a positioning boss 52 is provided on the outer periphery of the support sleeve main body 51, and a connecting section 59 that cooperates with the second mounting hole 45; a positioning groove 46 that cooperates with the positioning boss 52 is opened on one side of the second mounting hole 45, an annular mounting groove 58 is opened on the positioning boss 52, and a sealing gasket 6 is arranged in the mounting groove 58, and the sealing gasket 6 is used for sealing between the anti-theft valve body 4 and the positioning support sleeve 5. One side of the support sleeve main body 51 is provided with a mounting interface 53, a valve mounting port 11 is provided on the valve 1, and the mounting interface 53 is connected to the valve mounting port 11. A second channel 54 is opened inside the positioning support sleeve 5, a check valve 3 is installed in the second channel 54, and a positioning sleeve 55 is further provided on the other side of the support sleeve main body 51, and a third channel 56 that communicates with the second channel 54 is opened in the positioning sleeve 55.

[0029] In the above embodiment, a first mounting hole and a second mounting hole are respectively formed in the anti-theft valve body along the radial direction and the axial direction, and the first mounting hole and the second mounting hole are communicated through a first channel. A grease injection valve and a positioning support sleeve are respectively installed in the first mounting hole and the second mounting hole. A second channel and a third channel are axially formed in the positioning support sleeve, and a check valve is installed in the second channel. The above setting makes the grease injection channel in the anti-theft grease injection valve arranged at a right angle. Compared with the existing grease injection valve, it is not easy to remove the check valve and the grease injection valve at the same time, reducing the risk of pipeline oil theft.

[0030] In the above embodiment, although the risk of pipeline oil theft is reduced by setting the grease injection channel in the anti-theft grease injection valve at a right angle. However, there is still a risk that after the grease injection valve is removed, tools are used to open the check valve to steal the oil.

[0031] Preferably, an anti-theft cover 7 is installed at the end of the positioning sleeve 55. The anti-theft cover 7 has a spherical anti-theft cover body 71, and the anti-theft cover body 71 is used to block the grease injection channel along the direction of the first channel 44 to the third channel 56.

[0032] The diameter of the positioning sleeve 55 is smaller than the inner diameter of the second mounting hole 45, so that there is an installation gap between the positioning sleeve 55 and the second mounting hole 45. An L-shaped mounting portion 72 is provided on the outer periphery of the anti-theft cover body 71. An adjustment gasket 74 is provided between the mounting portion 72 and the end face of the positioning sleeve 55.

A plurality of fourth channels 73 are uniformly formed in the circumferential direction on the other side of the mounting portion 72. The fourth channels 73 only partially overlap the flow gap 57 in the axial direction. The grease can be injected into the valve through the first mounting hole 43, the first channel 44, the fourth channel 73, the flow gap 57, the third channel 56 and the check valve 3.

[0034] In the above embodiment, an anti-theft cover is installed at the end of the positioning sleeve. The anti-theft cover has a spherical anti-theft cover body, and the anti-theft cover body can block the grease injection channel along the direction of the first channel to the third channel. In some cases, the anti-theft cover body can guide some theft tools to move in the direction opposite to the check valve, so as to prevent the check valve from being directly opened by theft tools, reducing the risk of oil theft.

[0035] Meanwhile, an annular channel is opened at the end of the third channel, and a plurality of fourth channels are evenly opened in the circumferential direction of the installation part, so that the grease can be smoothly injected into the valve through the fourth channels and the annular channel. Since the positions of the fourth channels and the circulation gap are close to the outer periphery of the anti-theft cover, and the fourth channels and the circulation gap only partially overlap axially, the grease injection channels designed in this way can increase the operation difficulty of directly opening the check valve with theft tools, and further reduce the risk of stealing oil products.

[0036] In addition, an adjusting gasket is provided between the installation part and the positioning sleeve. The adjusting gasket can be used to adjust the axial distance between the fourth channel and the circulation gap. By increasing the thickness of the adjusting gasket, the axial distance between the fourth channel and the circulation gap can be increased, so that the grease can be more efficiently injected into the valve through the fourth channel and the circulation gap.

[0037] Preferably, a plurality of fifth channels 75 are opened on the anti-theft cover body 71. The fifth channels 75 are arranged close to the inner peripheral surface of the third channel 56, and the central axis of the fifth channel 75 intersects with the center of the sphere O of the anti-theft cover body 71.

[0038] In the above embodiment, a plurality of fifth channels are opened on the anti-theft cover body, which can improve the grease injection efficiency of the anti-theft grease injection valve; and the fifth channels are arranged close to the inner peripheral surface of the third channel, and the central axis of the fifth channel intersects with the center of the sphere of the anti-theft cover body. Such a setting can prevent theft tools from opening the check valve and reduce the risk of stealing oil products.
