In order to further explain the technical scheme of the invention, the invention is explained in detail by specific examples.
As shown in fig. 1 to 3, the invention relates to an explosion-proof valve capable of rotating by 360 degrees, which comprises a valve body, a water inlet, a water outlet, a control valve core 2 and a water flow channel.
As shown in fig. 2, the innovation of the present invention is that: the valve body is divided into a first valve body 11, a second valve body 12 and a third valve body 13.
Wherein the first valve body 11 has a housing chamber 111, the housing chamber 111 is formed with a first opening 112 and a second opening 113 in an axial direction of the first valve body 11, the control spool 2 is inserted into the housing chamber 111 from the first opening 112 and closes the first opening 112, the housing chamber 111 is formed with a third opening 114 in a radial direction of the first valve body 11, and the control spool 2 controls communication or blocking of the second opening 113 and the third opening 114. The control valve element 2 adopts a structure commonly used in the art, which is to switch between on and off by rotating, and the structure thereof is not described in detail herein.
The first valve body 11 is further sleeved with a first sealing ring 115 and a second sealing ring 116 which are axially arranged along the first valve body 11 at intervals, and the third opening 114 is positioned between the first sealing ring 115 and the second sealing ring 116; the first valve body 11 is further formed with a first connecting section 117 outside the second seal ring 116.
The second valve body 12 has a first through-hole 121 extending in the axial direction and a fourth opening 122 communicating with the first through-hole 121, the fourth opening 122 communicating with the third opening 114; the fourth opening 122 may be a water inlet or a water outlet, and is determined according to the specific situation.
The third valve body 13 has a second through hole 131 extending in the axial direction, the second through hole 131 being formed with a second connecting section 132 on one side near the first valve body 11, and a fifth opening 133 on the other side far from the first valve body 11, the fifth opening 133 being in communication with the second opening 113; one of the fifth opening 133 and the fourth opening 122 is a water inlet, and the other is a water outlet; in this embodiment, the fifth opening 133 is a water inlet, and the fourth opening 122 is a water outlet, mainly for the subsequent setting of the explosion proof valve core 3. Specifically, the first connecting section 117 is an externally threaded connecting portion 136, and the second connecting section 132 is an internally threaded connecting portion 136, which are connected to each other by threads.
The second valve body 12 is sleeved on the first sealing ring 115 and the second sealing ring 116 of the first valve body 11 through the first through hole 121 so as to realize 360-degree rotation of the second valve body 12 relative to the first valve body 11 and the third valve body 13, and the third valve body 13 is fixedly connected with the first connecting section 117 through the second connecting section 132.
In this way, according to the explosion-proof valve capable of rotating by 360 degrees, since the second valve body 12 can rotate by 360 degrees relative to the first valve body 11 and the third valve body 13, when the whole valve is installed at the corresponding position, the position of the second valve can be arbitrarily adjusted, so that the third valve body 13 and the second valve body 12 do not need to be excessively screwed for aligning the positions, only need to be properly screwed, and break points are not easy to form at the thread parts, thereby not only facilitating the operation of an installer, but also improving the overall performance of the valve.
In order to prevent the explosion-proof valve from causing large-scale water leakage when the explosion-proof valve is damaged, a blocking flange 134 is arranged between the second connecting section 132 and the fifth opening 133 of the third valve body 13, the fifth opening 133 is a water inlet, a water inlet channel 135 is formed between the blocking flange 134 and the fifth opening 133, an explosion-proof valve core 3 is further arranged in the water inlet channel 135 of the third valve body 13, the explosion-proof valve core 3 is provided with a sealing body 31 and an ejector rod 32, a sealing structure is formed between the sealing body 31 and the blocking flange 134, a water passing channel is formed between the sealing body 31 and the inner wall surface of the water inlet channel 135, and the first connecting section 117 of the first valve body 11 abuts against the ejector rod 32 to form a water passing gap between the sealing body 31 and the blocking flange 134.
The structural strength of the third valve body 13 is higher than that of the control valve core 2 and the first valve body 11, and the break point of the whole explosion-proof valve is formed at the control valve core 2 and the first valve body 11.
The invention preferably forms the breakpoint design at the control valve core 2 and the first valve body 11, and then is matched with the explosion-proof valve core 3, so that once the valve is damaged, the first connecting section 117 of the first valve body 11 loses the abutting action on the ejector rod 32 due to the damage of the control valve core 2 and the first valve body 11, the sealing body 31 can realize the sealing on the blocking flange 134 under the action of water flow, the self-intercepting action is realized, and a maintenance worker only needs to replace the first valve body 11 and the control valve core 2 during maintenance, thereby avoiding large-area leakage of the water flow and reducing the product risk.
As shown in fig. 3, in order that the third valve body 13 does not become a break point, a threaded connection portion 136 is formed on an outer wall surface of the third valve body 13, the threaded connection portion 136 is formed in a cone shape, and a thickness of the threaded connection portion 136 at a position close to the second connection section 132 is greater than a thickness of the fifth opening 133, as shown in fig. 3, D1 is greater than D2.
As shown in fig. 4, in order to perform the silencing function, the end of the outer ring of the sealing body 31 of the explosion-proof valve core 3 abuts against the inner wall surface of the water inlet channel 135, a plurality of silencing water channels 33 distributed in a ring shape are formed on the outer ring of the sealing body 31, and the depth of each silencing water channel 33 is smaller than the thickness of the blocking flange 134, so that the sealing effect of the sealing body 31 on the blocking flange 134 cannot be affected by the silencing water channels 33. By subdividing the water flow into a plurality of flow channels, the noise of the water flow can be well reduced.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
