Description

Technical Field

[0001] This utility model belongs to the field of end cap technology, and more specifically, it relates to an explosion-proof end cap with a pressure relief valve. Background Technology

[0002] Explosion-proof end caps with pressure relief valves are a special type of end cap that combines explosion-proof function with pressure relief device. They are widely used in pressure vessels, pipeline systems and other equipment that need to withstand internal pressure and have safety protection functions.

[0003] In the practical application of explosion-proof heads, some heads are fixed by threaded connection. However, this type of explosion-proof head usually has a stable structure and is prone to loosening due to external influences, which affects the normal use of the explosion-proof head. Utility Model Content

[0004] This disclosure relates to an explosion-proof end cap with a pressure relief valve, in order to solve the problem mentioned in the background art that some end caps are fixed by threaded connections. However, this type of explosion-proof end cap usually has a stable structure and is prone to loosening due to external influences, thus affecting the normal use of the explosion-proof end cap.

[0005] The explosion-proof end cap with pressure relief valve of this utility model is achieved by the following specific technical means:

[0006] This utility model provides an explosion-proof end cap with a pressure relief valve, comprising: an end cap base, wherein an explosion-proof connecting end cap is installed at one end of the end cap base; a reinforcing bracket is fixedly installed on the outer side of the explosion-proof connecting end cap in a cross shape; the end cap base further comprises: a fixing flange, wherein the fixing flange is designed in a circular shape and is integrally disposed at the other end of the end cap base.

[0007] As a preferred embodiment of this utility model, the end cap base further includes: a connector, the outer side of which is provided with a threaded connection, and the connector is integrally disposed at one end of the end cap base; the connector and the explosion-proof connecting end cap are connected by a thread.

[0008] As a preferred embodiment of this utility model, the explosion-proof connection head further includes: a connecting flange, which is welded to the top of the explosion-proof connection head; and a pressure relief valve body, which is fixedly installed on the top of the connecting flange by fixing screws.

[0009] As a preferred embodiment of this utility model, the explosion-proof connection end cap further includes a connecting block, which is hexagonal in shape and integrally disposed on the outside of the explosion-proof connection end cap.

[0010] As a preferred embodiment of this utility model, the reinforcing bracket further includes: a reinforcing slider, which is shaped like an arc block and slides on one side of the reinforcing bracket; a reinforcing block, which is shaped like a rectangular block and has an arc groove on one side; and the reinforcing block is integrally disposed at one end of the reinforcing slider.

[0011] As a preferred embodiment of this utility model, the reinforcing bracket further includes: a reinforcing screw, which rotates at one end of the reinforcing slider; a threaded connection between the reinforcing screw and the reinforcing bracket; and a transmission knob, which is fixed to one end of the reinforcing screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] After completing the fixed connection between the explosion-proof connecting head and the connector, to further enhance the stability and reliability of the connection structure, the operator only needs to gently rotate the transmission knob. This will cause the connected reinforcing screw to rotate, which in turn drives the reinforcing slider to move in a predetermined direction, pulling the reinforcing block to move synchronously. The bottom of the reinforcing block gradually approaches the head base until it finally makes tight contact with it. At this point, a compressive force is formed between the bottom of the reinforcing block and the head base, effectively preventing the explosion-proof connecting head from rotating due to external factors (such as vibration, impact, etc.). Once the explosion-proof connecting head rotates, the originally tight connection structure will gradually loosen, leading to a significant decrease in connection stability and potentially causing a series of safety hazards. The compressive force generated by the reinforcing block fundamentally eliminates this risk, ensuring that the connection structure remains in a stable and reliable state, providing a solid guarantee for the normal operation of the entire equipment or system.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] Example: As attached Figure 1 To be continued Figure 5 As shown:

[0023] This utility model provides an explosion-proof end cap with a pressure relief valve, comprising: an end cap base 1, an explosion-proof connecting end cap 2 installed at one end of the end cap base 1; a reinforcing bracket 3 fixedly installed in a cross shape on the outer side of the explosion-proof connecting end cap 2; the end cap base 1 further comprises: a fixing flange 101, the fixing flange 101 having a circular structure design, and the fixing flange 101 being integrally disposed at the other end of the end cap base 1; a connector 102, the connector 102 having a threaded connection on its outer side, and the connector 102 being integrally disposed at one end of the end cap base 1; the connector 102 and the explosion-proof connecting end cap 2 are threadedly connected.

[0024] The explosion-proof connection head 2 also includes: a connection flange 201, which is welded to the top of the explosion-proof connection head 2; a pressure relief valve body 202, which is fixedly installed on the top of the connection flange 201 by fixing screws; and a connection block 203, which is hexagonal in shape and integrally disposed on the outside of the explosion-proof connection head 2.

[0025] The reinforcing bracket 3 further includes: a reinforcing slider 301, which is shaped like an arc block and slides on one side of the reinforcing bracket 3; a reinforcing block 302, which is shaped like a rectangular block and has an arc groove on one side; the reinforcing block 302 is integrally set at one end of the reinforcing slider 301; a reinforcing screw 303, which rotates at one end of the reinforcing slider 301; the reinforcing screw 303 is threadedly connected to the reinforcing bracket 3; and a transmission knob 304, which is fixed to one end of the reinforcing screw 303.

[0026] The specific usage and function of this embodiment are as follows: During the use of the explosion-proof end cap, the end cap base 1 is connected to the pipeline through the fixed flange 101, and then the explosion-proof connecting end cap 2 is connected to the connecting head 102 by rotating the threaded connection, thereby completing the fixing of the explosion-proof end cap. When a pressure relief operation is required, the pressure relief valve body 202 can be activated to perform the pressure relief operation.

[0027] After the explosion-proof connecting head 2 and the connector 102 are fixedly connected, the reinforcing screw 303 can be rotated by rotating the transmission knob 304. The reinforcing screw 303 will drive the reinforcing block 302 to move through the reinforcing slider 301, so that the bottom of the reinforcing block 302 contacts the head base 1 to form a certain compressive force, preventing the explosion-proof connecting head 2 from rotating and causing a decrease in the connection stability between the head base 1 and the explosion-proof connecting head 2.
