Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal mines, and particularly relates to a high-pressure water valve that can rotate freely. Background Art
[0002] The high-pressure water valve, also known as a high-pressure water injector, is one of the indispensable equipments in coal mine production. It uses a high-pressure pump to send clear water to the water injector and pumps it into the cracks of the coal seam through the water pump, thereby reducing the moisture content of the coal seam, increasing the gas permeability of the coal seam, and improving the coal mining efficiency.
[0003] The existing water valve is composed of a shaft rod, bearings, an outer shell and a joint. Its water pressure resistance degree is low. During the use process, with the increase of the water pressure inside the drill pipe, the uncertain factors of joint leakage increase. At the same time, the rotation ability of the water valve decreases, which easily causes the water pipe to knot and break, resulting in unnecessary losses. Therefore, a high-pressure water valve that can rotate freely is proposed. By means of a combined gasket, it is ensured that there is no water leakage at the connection with the joint. Through the setting of the shaft rod, the outer shell can rotate. Summary of the Utility Model
[0004] Aiming at the problems in the prior art, the utility model provides a high-pressure water valve that can rotate freely. By means of a combined gasket, it is ensured that there is no water leakage at the connection with the joint. Through the setting of the shaft rod, the outer shell can rotate.
[0005] The technical solution adopted by the utility model to solve its technical problems is a high-pressure water valve that can rotate freely, including a water valve. A shaft rod is arranged on the surface of the water valve. An adjusting pad is sleeved outside the water valve. Deep groove ball bearings are sleeved at both ends outside the water valve. A spacer sleeve and a thrust bearing are respectively sleeved on the outside of the water valve between the deep groove ball bearings.
[0006] A joint is arranged at one end of the water valve. A combined gasket is sleeved outside the joint.
[0007] By adopting the above technical solution, the combined gasket seals at the connection between the water pipe and the joint to prevent water leakage. The settings of the deep groove ball bearing and the thrust bearing enable relative rotation between the water valve and the shaft rod.
[0008] Specifically, a seal is sleeved outside the adjusting pad.
[0009] Specifically, a sheath is sleeved on the outside of the water valve between the adjusting pad and the deep groove ball bearing.
[0010] Specifically, an outer shell is sleeved outside the water valve.
[0011] Specifically, the spacer sleeve is located on one side of the thrust bearing.
[0012] Advantages of the utility model:
[0013] (1) A high-pressure water valve that can rotate freely according to the present utility model. When the internal pressure of the drill pipe increases to 35 MPa, the thrust bearing effectively relieves the relative axial pressure between the two, achieving the purpose that they can still rotate relative to each other effectively under this high pressure.
[0014] (2) A high-pressure water valve that can rotate freely according to the present utility model. Two deep groove ball bearings are sleeved outside the water valve, enabling relative rotation between the outer shell and the shaft rod, and preventing the water pipe connected to the joint from knotting.
[0015] (3) A high-pressure water valve that can rotate freely according to the present utility model. A joint is sleeved outside the combined gasket, and the combined gasket is used for sealing between the joint and the water pipe to ensure that there is no water leakage at the connection between the water pipe and the joint.

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.
[0020] It is ensured that there is no water leakage at the connection with the joint through the combined gasket. Through the setting of the shaft rod, the outer shell can rotate. As Figure 1 shown, a high-pressure water valve that can rotate freely according to the present utility model includes a water valve 1. A shaft rod 10 is arranged on the surface of the water valve 1. An adjusting pad 2 is sleeved outside the water valve 1. Two deep groove ball bearings 9 are sleeved at both ends outside the water valve 1. A spacer sleeve 8 and a thrust bearing 4 are respectively sleeved on the outside of the water valve 1 between the deep groove ball bearings 9;
[0021] A joint 11 is arranged at one end of the water valve 1, and a combined gasket 6 is sleeved outside the joint 11.
[0022] During use, the combined gasket 6 seals at the connection between the water pipe and the joint 11 to prevent water leakage. The setting of the deep groove ball bearing 9 and the thrust bearing 4 enables relative rotation between the water valve 1 and the shaft rod 10.
[0023] Exemplarily, as Figure 1As shown, the utility model further includes a sealing member 3 sleeved outside the adjusting pad 2.
[0024] During use, the sealing member 3 seals between the adjusting pad 2 and the outer shell 12.
[0025] Exemplarily, as Figure 1 shown, the utility model further includes a sheath 7 sleeved outside between the water valve 1 and the deep groove ball bearing 9 on the outer side of the adjusting pad 2.
[0026] During use, the sheath 7 blocks between the adjusting pad 2 and the deep groove ball bearing 9.
[0027] Exemplarily, as Figure 1 shown, the utility model further includes an outer shell 12 sleeved outside the water valve 1.
[0028] During use, the outer shell 12 is used to protect the adjusting pad 2, thrust bearing 4, spacer sleeve 8, deep groove ball bearing 9, etc. sleeved outside the water valve 1.
[0029] Exemplarily, as Figure 1 shown, the utility model further includes a spacer sleeve 8 located on one side of the thrust bearing 4.
[0030] During use, the spacer sleeve 8 blocks between the deep groove ball bearing 9 and the thrust bearing 4.
[0031] When the utility model is in use, a joint 11 is sleeved outside the combined gasket 6, and the combined gasket 6 is used to seal between the joint 11 and the water pipe to ensure that there is no water leakage at the connection between the water pipe and the joint 11;
[0032] Two deep groove ball bearings 9 are sleeved outside the water valve 1, and a thrust bearing 4 is sleeved outside between the deep groove ball bearings 9 of the water valve 1, enabling relative rotation between the outer shell 12 and the shaft rod 10. When the internal pressure in the drill pipe increases to 35 MPa, the thrust bearing 4 effectively relieves the relative axial pressure between the two, achieving the purpose that they can still effectively rotate relative to each other under this high pressure;
[0033] The two deep groove ball bearings 9 effectively solve the difficulty of circumferential rotation, preventing the water pipe connected to the water valve 1 from knotting and effectively alleviating the problem of water pipe knotting.
