Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to an anti-slip safety valve. Background Technology

[0002] In modern life, water heaters have become an indispensable household appliance, providing people with a comfortable hot water experience. The safety valve of a water heater, as a key component ensuring the safe operation of the water heater, is of paramount importance. Currently, most water heater safety valves on the market are typically installed in the relevant pipe parts of the water heater via a threaded connection. Their working principle is based on an internal valve core assembly and spring structure. When the internal pressure of the water heater reaches the set opening pressure, the medium pressure overcomes the spring force, pushing the valve core to move, causing the safety valve to open and release pressure; when the pressure drops to the set closing pressure, the spring force pushes the valve core back to its original position, and the safety valve closes.

[0003] However, in practical use, existing water heater safety valves have revealed a serious problem: they are prone to stripping, leading to valve detachment. On one hand, water heaters are subjected to various factors during long-term operation, including water flow impact, vibration, and temperature changes. The continuous impact of water flow can gradually wear down the threads connecting the safety valve, especially when the water quality is poor and contains many impurities. Simultaneously, the vibrations generated during water heater operation subject the threaded connection to alternating stress, which over time can cause the threads to loosen and strip. On the other hand, improper installation, such as failing to tighten the threads to the specified torque or using a thread specification that does not match the water heater's interface, also increases the risk of stripping.

[0004] Therefore, there is an urgent need for an anti-slip safety valve that can effectively prevent slippage and ensure stable installation of the safety valve. Utility Model Content

Detailed Implementation

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1 to 2 As shown, in order to solve the above problems, this embodiment discloses an anti-slip safety valve, including:

[0036] Safety valve body 10, which is threadedly connected to the water heater;

[0037] Anti-slip structure 20, one end of which is detachably connected to the water heater and the other end is detachably connected to the safety valve body 10, is used to prevent the safety valve from slipping off;

[0038] The anti-slip structure 20 includes a first fixing part 21, a second fixing part 22, and an elastic band 23. One end of the elastic band 23 is fixedly connected to the first fixing part 21, and the other end is fixedly connected to the second fixing part 22. The first fixing part 21 is detachably connected to the water heater, and the second fixing part 22 is detachably connected to the safety valve body 10.

[0039] This invention, by incorporating an anti-slip structure 20, allows for the following installation steps: first, the safety valve body 10 is connected and fixed to the water heater; then, the first fixing part 21 is connected to the water heater; and finally, the elastic band 23 is pulled to connect the second fixing part 22 to the safety valve body 10, thereby further securing the safety valve body 10. During use, when the safety valve body 10 tends to loosen due to thread stripping, the tensile force of the elastic band 23 applies a reverse pulling force to the safety valve body 10, counteracting its tendency to detach. Simultaneously, the elastic buffer reduces thread wear caused by vibration during water heater operation. Compared to traditional water heater safety valves, this invention, through the combination of mechanical structure and elastic buffering, forms a dual mechanism of "active anti-detachment + passive protection," fundamentally solving the safety hazard caused by thread stripping, while also being both economical and safe. It addresses the problem of current water heater safety valves easily stripping during use, leading to valve detachment.

[0040] In one embodiment, to facilitate the connection of the first fixing part 21 to the water heater pipe, it is further preferred that the first fixing part 21 includes an open ring 200, which can be snapped onto the water heater pipe, and one end of the elastic band 23 is fixedly connected to the open ring 200.

[0041] The open ring 200 adopts a flexible annular open structure and is made of metal.

[0042] The open ring 200 is designed to be easily snapped onto the water heater pipe, thus facilitating the connection between the first fixing part 21 and the water heater pipe.

[0043] In one embodiment, to facilitate the connection between the second fixing part 22 and the safety valve body 10, it is further preferred that the second fixing part 22 includes an elastic rubber ring 201. The safety valve body 10 is provided with a rubber ring groove 100 that cooperates with the elastic rubber ring 201. The elastic rubber ring 201 can be fitted into the rubber ring groove 100 on the safety valve body 10 and is detachably connected to the safety valve body 10. One end of the elastic band 23 is fixedly connected to the elastic rubber ring 201.

[0044] The elastic rubber ring 201 is made of rubber material.

[0045] The elastic rubber ring 201 can be easily fitted directly into the rubber ring groove 100 on the safety valve body 10, thereby facilitating the connection between the second fixing part 22 and the safety valve body 10.

[0046] The safety valve body 10 can be a safety valve of the prior art, or it can adopt the following safety valve structure:

[0047] like Figures 3 to 9 As shown, in one embodiment, as a further preferred embodiment, the safety valve body 10 includes a valve body assembly 11, a valve core assembly 12, and an elastic component 13. The valve body assembly 11 includes an upper valve body 101 and a lower valve body 102. The lower end of the upper valve body 101 can be inserted into the top of the lower valve body 102 and is threadedly connected to the top of the lower valve body 102. The upper valve body 101 is provided with a flow chamber 103, and the lower valve body 102 is provided with a mounting cavity 104 communicating with the flow chamber 103. The valve core assembly 12 is disposed in the mounting cavity 104 and is clearance-fitted with the mounting cavity 104. One end of the valve core assembly 12 contacts the bottom of the upper valve body 101 to isolate the flow chamber 103 and the mounting cavity 104. The elastic component 13 is disposed in the mounting cavity 104 and located at the other end of the valve core assembly 12 to provide support for the valve core assembly 12. The elastic component 13 is detachably connected to the mounting cavity 104.

[0048] The valve core assembly 12 includes a mounting sleeve 105, a rubber sleeve 106, and a sealing ball 107. The mounting sleeve 105 is clearance-fitted with the mounting cavity 104. The top of the mounting sleeve 105 is provided with a first mounting groove 108. The rubber sleeve 106 is fixedly disposed in the first mounting groove 108. The top of the rubber sleeve 106 is provided with a second mounting groove 109. One end of the sealing ball 107 is fixedly disposed in the second mounting groove 109. The top of the rubber sleeve 106 can contact the bottom of the upper valve body 101, and the other end of the sealing ball 107 can contact the bottom of the upper valve body 101 and extend into the flow cavity 103 to form a contact seal with the flow cavity 103.

[0049] The elastic component 13 includes a support spring 110 and an adjusting head 111. The bottom of the mounting sleeve 105 is provided with a first connecting groove 112, and the top of the adjusting head 111 is provided with a second connecting groove 113. One end of the support spring 110 is located in the first connecting groove 112 and is fixedly connected to the bottom of the mounting sleeve 105. The other end of the support spring 110 is located in the second connecting groove 113 and is fixedly connected to the top of the adjusting head 111. The adjusting head 111 is threadedly connected to the inner wall of the mounting cavity 104.

[0050] The bottom of the adjusting head 111 is provided with an adjusting groove 114 that communicates with the second connecting groove 113.

[0051] During use, when the liquid pressure inside the water heater pipe increases, the liquid enters the flow chamber 103. Simultaneously, due to the increased pressure, the liquid in the flow chamber 103 exerts work on the sealing ball 107, generating a downward thrust, causing the sealing ball 107 to move downwards. This, in turn, moves the mounting sleeve 105 and rubber sleeve 106 downwards, further compressing the support spring 110. At this point, the flow chamber 103 connects to the mounting chamber 104, and the liquid in the flow chamber 103 enters the mounting chamber 104, then flows out from the second connecting groove 113 and the adjusting groove 114, thus achieving pressure reduction. When the pressure inside the water heater pipe returns to normal, the support spring 110 resets, generating an upward thrust on the mounting sleeve 105 and rubber sleeve 106, causing them to move upwards. This allows the sealing ball 107 to re-enter the flow chamber 103, forming a contact seal with the flow chamber 103. During installation, the position of the adjusting head 111 can be adjusted through the adjusting groove 114 to change the deformation state of the support spring 110, thereby changing the preset value of the pressure.

[0052] To improve the sealing at the connection between the upper valve body 101 and the lower valve body 102, this embodiment is modified from the above embodiment. The difference from the above embodiment is that a limiting ring 115 is provided in the mounting cavity 104. The limiting ring 115 is fixedly connected to the inner side wall of the mounting cavity 104. The bottom of the upper valve body 101 can contact and limit the movement with the limiting ring 115. A sealing gasket 116 is provided on the side of the limiting ring 115 that contacts the bottom of the upper valve body 101. The sealing gasket 116 is embedded in the limiting ring 115.

[0053] The sealing gasket 116 is designed to improve the sealing performance at the connection between the upper valve body 101 and the lower valve body 102. When connecting the upper valve body 101 and the lower valve body 102, sealing tape needs to be wrapped around the lower end of the upper valve body 101 to further improve the sealing performance between the upper valve body 101 and the lower valve body 102.

[0054] To improve the sealing between the upper valve body 101 and the water heater, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the upper valve body 101 is provided with a threaded connecting pipe 117 at the top. The threaded connecting pipe 117 is fixedly connected to the top of the upper valve body 101 and communicates with the flow cavity 103. The threaded connecting pipe 117 is provided with an annular sealing groove 118. A sealing ring 119 is provided in the annular sealing groove 118. The sealing ring 119 is fitted in the annular sealing groove 118 and is detachably connected to the threaded connecting pipe 117.

[0055] The sealing ring 119 is designed to improve the sealing performance between the upper valve body 101 and the water heater. When connecting the upper valve body 101 to the water heater, sealing tape needs to be wrapped around the threaded connecting pipe 117 to further improve the sealing performance between the upper valve body 101 and the water heater.

[0056] To accommodate water heater pipes of different diameters, this embodiment modifies the above embodiment. The difference is that the first fixing part 21 includes a pair of arc-shaped locking blocks 202, which are detachably connected by a bolt assembly 203. The pair of arc-shaped locking blocks 202 can be sleeved on the water heater pipe and fixedly connected to the water heater pipe by the bolt assembly 203. An arc-shaped rubber pad 204 is provided on one side of the pair of arc-shaped locking blocks 202 that contacts the water heater pipe. One side of the arc-shaped rubber pad 204 is fixedly connected to the arc-shaped locking block 202, and the other side contacts the water heater pipe. One end of the elastic band 23 is fixedly connected to one of the arc-shaped locking blocks 202.

[0057] A pair of arc-shaped locking blocks 202 are detachably connected by a bolt assembly 203, which can easily accommodate water heater pipes of different diameters. The bolt assembly 203 can be any existing bolt assembly 203 that can achieve the function of this utility model.

[0058] The bolt assembly 203 includes a bolt, a nut adapted to the bolt, and a washer. The washer is fitted onto the bolt with a clearance fit, and the nut is fitted onto the bolt and threadedly connected to it. Two fixing blocks 205, which mate with the bolt, are fixedly mounted on both sides of the arc-shaped locking block 202. The fixing blocks 205 are fixedly connected to the arc-shaped locking block 202. One end of the bolt passes through one of the fixing blocks 205 on each side of the arc-shaped locking block 202. The nut and washer are fitted onto the end of the bolt.

[0059] To facilitate the installation of the second fixing part 22, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the second fixing part 22 includes a metal ring 206. An annular groove 120 is provided between the upper valve body 101 and the lower valve body 102. The metal ring 206 is sleeved in the annular groove 120. One side of the metal ring 206 contacts the upper valve body 101, and the other end contacts the lower valve body 102. When the upper valve body 101 and the lower valve body 102 are connected, the metal ring 206 is fixed in the annular groove 120.

[0060] During installation, first, the metal ring 206 is placed on the lower end of the upper valve body 101, and then the lower end of the upper valve body 101 is screwed into the lower valve body 102 until the upper valve body 101 presses the metal ring 206 into the annular groove 120. At this time, the bottom of the upper valve body 101 contacts the limiting ring 115.

[0061] Working principle of this utility model:

[0062] This invention utilizes an anti-slip structure 20. During installation, the safety valve body 10 is first connected and fixed to the water heater. Then, the first fixing part 21 is connected to the water heater. Next, the elastic band 23 is pulled to connect the second fixing part 22 to the safety valve body 10, thus further securing the safety valve body 10. During use, when the safety valve body 10 tends to loosen due to thread stripping, the tensile force of the elastic band 23 applies a reverse pulling force to the safety valve body 10, counteracting its tendency to fall off. Simultaneously, the elastic buffer reduces thread wear caused by vibration during water heater operation.

[0063] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
