Description

Technical Field

[0001] The utility model belongs to the technical field of an automatic exhaust hot mixing valve, and more specifically, particularly relates to an automatic exhaust hot mixing valve. Background Art

[0002] During the development of oil fields, as oil and gas are produced, a large amount of casing gas will be generated in the casing of the pumping well. If the gas is not discharged in time, it will affect the normal operation of the deep well pump downhole. During the development of oil fields, a wellhead constant pressure vent valve is widely used to automatically discharge the gas in the casing to increase the oil recovery efficiency. Among them, Chinese patent CN202222775192.6 discloses an automatic exhaust device, including a valve body and a valve core. The valve body is T-shaped and has a T-shaped valve cavity inside. The valve core is installed in the T-shaped valve cavity. The end of the valve body is respectively provided with an oil inlet, a vent and a connection port. The connection port is connected with an adjusting nut through a thread, and the central axis of the adjusting nut is penetrated and connected with an adjusting rod. The bottom end of the adjusting rod is arranged inside the T-shaped valve cavity and connected with a spring seat. The valve body is provided with a connecting hole on the side close to the vent, and a pressure gauge is sealed and connected through the connecting hole. The utility model can realize fast and accurate adjustment and setting of the deflation pressure, so that the automatic exhaust device has the function of realizing high and low pressure automatic exhaust. Through the setting of the sealing gasket and the sealing ring, the sealing between the adjusting nut and the valve body and the adjusting rod and the adjusting nut can be effectively improved, so as to maximize the guarantee that the internal gas will not leak, and the safety of use is relatively high.

[0003] Based on the above, the inventors have discovered the following problems: when the device in the above patent is in use, since the valve core and the spring seat are fixedly connected, the spring needs to be replaced when it has been used for a long time. However, the device in the above patent cannot replace the spring, and can only replace the spring seat, which is costly.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic exhaust hot mixing valve is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an automatic exhaust hot mix valve to solve the problem that the spring of the current automatic exhaust hot mix valve cannot be replaced during use, resulting in high costs.

[0006] The purpose and effect of the automatic exhaust hot mixing valve of the utility model are achieved by the following specific technical means:

[0007] An automatic exhaust hot mixing valve comprises an automatic exhaust valve body, a connecting piece is installed on the surface of the automatic exhaust valve body, an oil inlet pipe and an air outlet pipe are installed on the surface of the automatic exhaust valve body, a spring seat is installed in the automatic exhaust valve body, a spring is installed in the spring seat, a movable plate is installed on the surface of the spring, a connecting rod is installed on the surface of the movable plate, the connecting rod extends to the outside through the connecting piece, a first thread is provided on the surface of the connecting rod, a valve core is installed on the surface of the spring seat, and a mechanism for disassembling the valve core is installed in the spring seat.

[0008] Furthermore, the mechanism for removing the valve core includes a raised block installed on the surface of the valve core, the surface of the raised block is provided with a second thread, the spring seat is provided with a thread groove matching the second thread, and the valve block is in contact with the inner wall of the oil inlet pipe.

[0009] Furthermore, a third thread is provided on the surface of the automatic exhaust valve body, and a thread groove matching the third thread is provided in the connecting piece.

[0010] Furthermore, a hexagonal block is installed on the surface of the connecting piece.

[0011] Furthermore, a handle is installed on the surface of the connecting rod, the handle passes through the connecting rod, and blocking blocks are installed at both ends of the handle.

[0012] Furthermore, the blocking block is detachable.

[0013] Furthermore, a limiting groove is provided on the surface of the automatic exhaust hot mixing valve, a limiting block is installed on the surface of the spring seat, and the limiting groove and the limiting block match each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model cooperates with a spring seat, a spring, a movable plate, a connecting rod, a first thread, a valve core, a protruding block and a second thread in use. When in use, the connecting rod can be rotated. When the connecting rod rotates, it will move up and down under the action of the thread. The movement of the connecting rod will drive the movable plate to move. The movement of the movable plate will drive the contraction of the spring, thereby adjusting the elastic force of the spring. When the spring needs to be replaced, it is only necessary to take out the spring seat and then rotate the valve core. The rotation of the valve core will drive the protruding block to rotate, thereby removing the valve core, and then taking out the spring and replacing it with a new spring. Through the above design, the spring can be quickly replaced without replacing the spring seat, thereby reducing the cost.

[0016] By using the third thread, the connecting piece can be easily removed from the automatic exhaust valve body;

[0017] By using the hexagonal piece, the connecting piece can be removed from the automatic exhaust valve body more conveniently;

[0018] Through the detachable design, the handle can be removed, and then the connecting rod can be rotated to remove the connecting rod from the connecting part. While replacing the spring, the connecting rod can be pushed downward to remove the connecting rod and the movable plate. Through the above design, the connecting rod, movable plate and handle can be quickly replaced, which improves practicality. BRIEF DESCRIPTION OF THE DRAWINGS
