Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting equipment technology, and specifically relates to a horizontal sliding control valve. Background Technology

[0002] Chinese Patent No. CN213159101U discloses a fire hose with pressure detection, relating to the field of fire equipment technology. The key technical features are: a hose body, a ball core, and an operating handle. The hose body has a connected inlet and outlet channel, with an installation cavity between them. The ball core is rotatably mounted within the installation cavity. The operating handle controls the ball core to connect the inlet and outlet channels. The ball core has a connecting hole that connects to the installation cavity. A fixing hole connecting to the installation cavity is provided on the outer side of the hose body. A pressure detector is installed within the fixing hole to detect the pressure within the installation cavity.

[0003] The above technical solution has the following defects: When the above fire hose is in use, it relies on the operation handle switch to drive the ball core to rotate in order to control the flow of water. However, when the ball valve core is in a partially open state, the high-pressure water flow will continuously impact the outer wall of the ball core. If the operator does not hold the operation handle at this time, the water pressure will drive the ball core to rotate on its own, resulting in a sudden full opening or sudden closing. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a horizontal sliding control valve. The technical problem to be solved by this invention is: how to overcome the impact of high-pressure water flow in order to maintain a stable opening.

[0005] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a horizontal sliding control valve, including a valve body, a water passage and a sealing element are provided in the valve body, a control tube is slidably arranged in the water passage, the control tube is coaxial with the water flow direction, the control tube can cooperate with the sealing element to isolate the water passage, a linkage groove is provided on the control tube, a handle is rotatably arranged on the valve body, a linkage block is eccentrically arranged on the handle, the linkage block is inserted into the linkage groove, when the handle is rotated in the horizontal direction, the linkage block abuts against the side wall of the linkage groove, thereby driving the control tube to slide along the water passage, so that the gap between the control tube and the sealing element for water flow increases or decreases.

[0006] In the above-mentioned sliding control valve, a sealing ring is provided on the outer wall of the sealing element. When the control tube slides so that one end is sleeved on the outside of the sealing element, the sealing ring seals the control tube and the sealing element.

[0007] In the aforementioned type of horizontal sliding control valve, the sealing element is provided with a flow guiding arc surface, which faces the water inlet end of the water passage.

[0008] In the aforementioned type of horizontal sliding control valve, the linkage groove is annular.

[0009] In the aforementioned type of horizontal sliding control valve, a limiting hole is provided on the valve body for limiting the movement of the linkage block, and the linkage block passes through the limiting hole.

[0010] In the aforementioned type of horizontal sliding control valve, a fastener is installed on the valve body, the fastener passes through one end of the handle, and the handle can rotate about the fastener as an axis.

[0011] In the above-mentioned sliding control valve, at least two sealing rings are provided on the inner wall of the valve body, and both sealing rings are used to seal the valve body and the control pipe.

[0012] In the above-mentioned horizontal sliding control valve, the valve body includes a valve body and a movable block. The movable block is rotatably disposed within the valve body. The handle is connected to the movable block. The linkage block passes through the movable block and is inserted into the linkage groove.

[0013] In the aforementioned type of horizontal sliding control valve, a limiting protrusion is provided on the valve body, which is used to limit the rotation stroke of the handle.

[0014] In the aforementioned type of horizontal sliding control valve, the outer wall of the movable block is provided with an annular flange, and the upper surface of the annular flange abuts against the inner wall of the valve body.

[0015] In summary, the beneficial effects of this utility model compared to the prior art are as follows: By sliding the control tube, the gap between the control tube and the seal is changed, thereby regulating the water flow and switching it on and off. Since the control tube is set along the water flow direction, the water flows through the control tube, thus avoiding direct impact from the water flow on the control tube and effectively ensuring the stability of the control tube's position, thereby maintaining the stability of the opening.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0019] A type of rotary sliding control valve, such as Figures 1 to 4 As shown, it includes valve body 1. It should be noted that valve body 1 can be a two-section valve body 1 or a multi-section valve body 1. There is no specific limitation on this. Valve body 1 can be connected to the water hose by a threaded structure or by a quick-connect interface. There is no specific limitation on this.

[0020] In this embodiment, Figure 1 The valve body consists of two sections and is connected to the water hose via a threaded structure. Figure 2 The valve body is a three-section type and uses a threaded structure for connection with the water hose. Figure 3 It has a two-section valve body 1 and uses a quick-connect interface for connection with water hoses. Figure 4 It has a three-section valve body 1 and uses a quick-connect interface to connect to the water hose.

[0021] The valve body 1 is provided with a water flow channel 2 and a sealing element 3. A control pipe 4 is slidably arranged in the water flow channel 2. The control pipe 4 is arranged along the water flow direction. The control pipe 4 can cooperate with the sealing element 3 to isolate the water flow channel 2. A linkage groove 5 is provided on the control pipe 4. A handle 6 is rotatably arranged on the valve body 1. A linkage block 7 is eccentrically arranged on the handle 6. The linkage block 7 is inserted into the linkage groove 5.

[0022] Specifically, a fastener 11 is installed on the valve body 1. The fastener 11 is preferably a bolt. The bolt is threaded to the valve body 1. The fastener 11 passes through one end of the handle 6, and the handle 6 can rotate about the fastener 11 as an axis.

[0023] In this embodiment, the linkage groove 5 is annular, which facilitates the quick insertion of the linkage block 7 into the linkage groove 5, reduces assembly difficulty, and improves assembly efficiency.

[0024] When the handle 6 is rotated horizontally, the linkage block 7 abuts against the side wall of the linkage groove 5, thereby causing the control pipe 4 to slide along the water flow channel 2, which increases or decreases the gap between the control pipe 4 and the seal 3 through which the water flows.

[0025] Specifically, when the control pipe 4 slides closer to the seal 3, the gap between the control pipe 4 and the seal 3 gradually decreases; conversely, when the control pipe 4 slides away from the seal 3, the gap between the control pipe 4 and the seal 3 gradually increases. That is, by changing the gap between the control pipe 4 and the seal 3, the flow rate of the water outlet can be regulated.

[0026] It should be noted that when the control pipe 4 slides close to the seal 3 until one end of the control pipe 4 is fitted onto the outside of the seal 3, the gap between the control pipe 4 and the seal 3 cannot be used for water flow, thereby blocking the water flow channel 2.

[0027] Furthermore, a sealing ring 8 is provided on the outer wall of the sealing element 3. When the control tube 4 slides so that one end is fitted onto the outside of the sealing element 3, the sealing ring 8 seals the control tube 4 and the sealing element 3. The sealing ring 8 can effectively improve the sealing performance between the control tube 4 and the sealing element 3, preventing water from seeping between them.

[0028] It should be noted that in this embodiment, since the water flow passes through the control pipe 4, direct impact on the control pipe 4 can be avoided. Therefore, the position of the control pipe 4 can be effectively stabilized, thereby maintaining the stability of the opening and ensuring the stability of the water flow rate.

[0029] The inner wall of the valve body 1 is provided with at least two sealing rings 12. Both sealing rings 12 are used to seal between the valve body 1 and the control pipe 4. Specifically, the two sealing rings 12 seal the two ends of the valve body 1 and the control pipe 4 respectively to prevent water from leaking out from the two ends of the valve body 1 and the control pipe 4.

[0030] In this embodiment, the seal 3 is threadedly connected to the valve body 1, which facilitates the maintenance and replacement of the seal 3. The seal 3 is provided with a flow guiding arc surface 9, which faces the water inlet end of the water passage 2. The flow guiding arc surface 9 can guide the water flow and guide the water flow through the gap between the seal 3 and the control pipe 4, thereby achieving a stable flow effect. Moreover, the flow guiding arc surface 9 can also effectively reduce the impact of the water flow on the seal 3.

[0031] The valve body 1 has a limiting hole 10 for limiting the linkage block 7. The linkage block 7 passes through the limiting hole 10. The linkage block 7 is limited by the abutting action between the linkage block 7 and the side wall of the limiting hole 10, thereby limiting the stroke of the linkage block 7 and thus limiting the stroke of the control tube 4. Example 2:

[0032] like Figures 5 to 8 As shown, the difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the valve body 1 includes a valve body 13 and a movable block 14. The movable block 14 is rotatably disposed inside the valve body 13. The handle 6 is connected to the movable block 14. Specifically, the handle 6 is connected to the movable block 14 by a fixing bolt 17. The linkage block 7 passes through the movable block 14 and is inserted into the linkage groove 5. That is, the movable block 14 is equipped with a through hole for the movable block 14 to pass through.

[0033] A limiting protrusion 15 is provided on the valve body 13. The limiting protrusion 15 is used to limit the rotation stroke of the handle 6. Specifically, the limiting protrusion 15 is an annular structure with a notch, that is, the handle 6 is located in the notch. When the handle 6 rotates, the handle 6 can abut against the two ends of the limiting protrusion 15, thereby limiting the stroke of the handle 6, and thus limiting the stroke of the control tube 4. Compared with the first embodiment, this embodiment eliminates the limiting hole 10. The purpose of limiting the stroke of the control tube 4 is achieved by limiting the handle 6 through the limiting protrusion 15.

[0034] The outer side wall of the movable block 14 is provided with an annular flange 16, and the upper surface of the annular flange 16 abuts against the inner side wall of the valve body 13, thereby preventing the movable block 14 from detaching from the valve body 13.

[0035] In this embodiment, Figure 5 The valve body consists of two sections and is connected to the water hose via a threaded structure. Figure 6 The valve body is a three-section type and uses a threaded structure for connection with the water hose. Figure 7 It has a two-section valve body 1 and uses a quick-connect interface for connection with water hoses. Figure 8 It has a three-section valve body 1 and uses a quick-connect interface to connect to the water hose.

[0036] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
