Description

Technical Field

[0001] This utility model relates to the field of gate valves, specifically to a gate valve device for the discharge port of a kitchen cart. Background Technology

[0002] Gate valves, as one of the most commonly used shut-off valves, typically consist of two parts: a gate valve body and a movable gate. The valve is opened and closed by the movement of the movable gate in coordination with the gate valve body. Gate valves have a wide range of applications, such as at the discharge point of food waste collection carts. Food waste collection carts are mainly used to collect and transport food waste and kitchen scraps generated by the catering industry, hotels, canteens, and residential households. A search revealed Chinese patent application number "CN220337502U", which discloses an adjustable gate valve, including a gate valve body and a gate. The gate valve body includes a handwheel, a valve stem, a valve body, and a valve port. The handwheel is located at the top of the gate valve, the valve stem is connected to the handwheel, and the gate is connected to the valve stem. The valve body has a hollow internal structure, with the gate placed inside the valve body. The valve port is located on the lower side of the valve body, and a valve core is installed inside the valve port.

[0003] Existing manual gate valves typically control the opening and closing by moving the gate plate through the rotation of a screw. Over time, the screw surface rusts, making it difficult to rotate and requiring considerable effort to move the valve plate up and down.

[0004] Therefore, the present invention urgently needs to solve the problem of providing a gate valve device for the discharge port of a kitchen cart that can drive the valve stem to move the valve plate vertically up and down by simply flipping the actuator during use, so that the discharge pipe is in an open or closed state, and locks the actuator by a locking mechanism. The whole operation is very simple and fast, which improves work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to overcome the limitations of existing technologies that rely on the rotation of a screw to move the gate plate for control of opening and closing. Over time, the screw surface rusts, making it difficult to rotate and resulting in considerable effort in raising and lowering the valve plate. This invention provides a gate valve device for a kitchen cart's discharge port that allows the valve stem to move the valve plate vertically up and down simply by flipping the actuator, thus opening or closing the discharge pipe. A locking mechanism further locks the actuator, making the entire operation simple, fast, and efficient.

[0006] To achieve the above objectives, this utility model provides a gate valve device for the discharge port of a catering vehicle, comprising: a discharge pipe fixed to the discharge port of the liquid storage tank of the catering vehicle, a gate valve body detachably mounted on the discharge pipe, and an actuator for raising and lowering the valve plate of the gate valve body to connect or disconnect the interior of the gate valve body from the discharge pipe. The top of the gate valve body is vertically connected and fixedly mounted with a housing that works in conjunction with the valve plate. Inside the housing, a guide block is horizontally and vertically mounted. The bottom end of the guide block is fixedly connected to the valve plate, and the top end of the guide block is vertically fixedly mounted with a valve stem. The top end of the valve stem extends from the top end of the housing and is movably mounted with an actuator that can switch between a horizontal and a vertical state to drive the valve stem to rise and fall. The top end of the housing is provided with a locking mechanism that can lock the actuator in either a horizontal or vertical state. A first spring is sleeved on the valve stem inside the housing, and the two ends of the first spring are fixed to the top of the housing and the guide block, respectively.

[0007] Preferably, the locking mechanism includes: a first pin assembly and a second pin assembly with identical structures; wherein, A pair of No. 1 mounting bases and a pair of No. 2 mounting bases are vertically and symmetrically fixed on the top of the housing and one side of the housing on both sides of the actuator, and a No. 1 pin assembly and a No. 2 pin assembly are respectively fixedly provided on each No. 1 mounting base and each No. 2 mounting base. A No. 1 locking hole and a No. 2 locking hole are respectively opened at intervals on both sides of the actuator to cooperate with the pair of No. 1 pin assemblies and the pair of No. 2 pin assemblies.

[0008] Preferably, the first pin assembly or the second pin assembly comprises: a pin and a second spring; wherein, Each mounting base No. 1 or No. 2 is horizontally perforated with a movable T-shaped pin, and the bottom end of each pin located between two mounting bases No. 1 or two mounting bases No. 2 is vertically fixed with a support plate, and a No. 2 spring is horizontally fixed between each mounting base No. 1 or No. 2 and the support plate.

[0009] Preferably, the top of the n-shaped actuator is horizontally rotatably provided with a support rod, the top of the valve stem has a through hole for the support rod to pass through, and the top of the housing has a vertically penetrating guide hole for the valve stem to pass through.

[0010] Preferably, the top spaced portion of the housing is recessed inward to form two limiting grooves that cooperate with the bottom ends of the two side walls of the actuator.

[0011] Preferably, a sealing gasket is fixedly mounted horizontally at the bottom end of the guide block.

[0012] According to the above technical solution, the beneficial effects of the gate valve device for the discharge port of the catering cart provided by this utility model in use are as follows: (1) The top of the valve stem extends vertically from the top of the housing and is movably mounted inside the actuator, so that the actuator can drive the valve stem to rise vertically during the process of flipping from the horizontal state to the vertical state, thereby driving the valve plate to move from the inside of the gate valve body to the inside of the housing. During the rising process, the No. 1 spring is compressed, thereby connecting the discharge pipe and the inside of the gate valve body, so that the liquid in the storage tank of the kitchen cart can be discharged through the discharge pipe.

[0013] (2) When the actuator flips from a vertical to a horizontal position and abuts against the top of the housing, under the force of the first spring, the valve stem pushes the guide block to drive the valve plate down vertically until the bottom of the valve plate abuts against the inner wall of the gate valve body, thereby isolating the inside of the gate valve body from the discharge pipe and sealing the discharge pipe. When the bottom of the valve plate abuts against the inner wall of the gate valve body, the first spring is still in a tensioned state, and under the tension of the first spring, the valve plate is tightly abutted against the inner wall of the gate valve body.

[0014] (3) The locking mechanism can lock the actuator in a horizontal or vertical state, thereby preventing the actuator from moving and causing the valve stem to rise or fall. In other words, it indirectly locks the valve stem and valve plate after they have risen or fallen.

[0015] In summary, during use, this utility model only requires flipping the actuator to drive the valve stem to move the valve plate vertically up and down so that the discharge pipe is in an open or closed state. The actuator is locked by the locking mechanism. The whole operation is very simple and fast, which improves work efficiency.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] like Figure 1-6 As shown, the present invention provides a gate valve device for the discharge port of a catering vehicle, comprising: a discharge pipe 1 fixed on the discharge port of the liquid storage tank of the catering vehicle, a gate valve body 2 detachably mounted on the discharge pipe 1, and an actuator 7 for raising and lowering the valve plate 3 of the gate valve body 2 to connect or disconnect the interior of the gate valve body 2 from the discharge pipe 1. The top of the gate valve body 2 is vertically connected and fixedly mounted with a housing 4 that works with the valve plate 3. Inside the housing 4, a guide block is horizontally and vertically mounted. The bottom end of the guide block is fixedly connected to the valve plate 3, and the top end of the guide block is vertically fixedly mounted with a valve stem 5. The top end of the valve stem 5 extends out from the top end of the housing 4 and is movably mounted with an actuator 7 that can switch between horizontal and vertical states to drive the valve stem 5 to rise and fall. The top end of the housing 4 is provided with a locking mechanism that can lock the actuator 7 in either the horizontal or vertical state. A first spring 6 is sleeved on the valve stem 5 inside the housing 4. The two ends of the first spring 6 are fixed to the top of the housing 4 and the guide block, respectively.

[0021] In the above scheme, the top of the valve stem 5 extends vertically from the top of the housing 4 and is movably mounted inside the actuator 7. This allows the actuator 7 to rotate from a horizontal to a vertical position, thereby driving the valve stem 5 to rise vertically. This causes the valve plate 3 to move from inside the gate valve body 2 into the housing 4. During the upward movement, the first spring 6 is compressed, thereby connecting the discharge pipe 1 with the gate valve body 2, so that the liquid in the storage tank of the kitchen cart can be discharged through the discharge pipe 1.

[0022] Conversely, when the actuator 7 flips from a vertical to a horizontal position and abuts against the top of the housing 1, under the force of the first spring 6, the valve stem 5 pushes the guide block, causing the valve plate 3 to descend vertically until the bottom end of the valve plate 3 abuts against the inner wall of the gate valve body 2, thereby isolating the interior of the gate valve body 2 from the discharge pipe 1 and sealing the discharge pipe 1. Furthermore, when the bottom end of the valve plate 3 abuts against the inner wall of the gate valve body 2, the first spring 6 remains tensioned, and under the tension of the first spring 6, the valve plate 3 is tightly pressed against the inner wall of the gate valve body 1.

[0023] Finally, the locking mechanism can lock the actuator 7 in either a horizontal or vertical position, thereby preventing the actuator 7 from moving and causing the valve stem 5 to rise or fall. This indirectly locks the valve stem 5 and valve plate 3 after they have risen or fallen.

[0024] In summary, during use, this utility model can drive the valve stem 5 to move the valve plate 3 vertically up and down by simply flipping the actuator 7, so that the discharge pipe 1 is in an open or closed state. The actuator 7 is locked by the locking mechanism. The whole operation is very simple and fast, which improves work efficiency.

[0025] In a preferred embodiment of this utility model, the locking mechanism includes: a first pin assembly 8 and a second pin assembly 9 with identical structures; wherein, On the top of the housing 4 located on both sides of the actuator 7, and on one side of the housing 4, a pair of No. 1 mounting bases and a pair of No. 2 mounting bases are respectively vertically and symmetrically fixed. Each No. 1 mounting base and each No. 2 mounting base are respectively fixedly provided with a No. 1 pin assembly 8 and a No. 2 pin assembly 9. On both sides of the actuator 7, there are No. 1 locking holes 10 and No. 2 locking holes 11 that are spaced apart and used to cooperate with the pair of No. 1 pin assemblies 8 and the pair of No. 2 pin assemblies 9.

[0026] In the above scheme, the first pin assembly 8 and the second pin assembly 9, in cooperation with the first locking hole 10 and the second locking hole 11 on the actuator 7, can lock the actuator 7 in either a horizontal or vertical state, preventing the actuator 7 from moving and causing the valve stem 5 to rise or fall. This indirectly locks the valve stem 5 and valve plate 3 after they have risen or fallen.

[0027] In a preferred embodiment of this utility model, the first pin assembly 8 or the second pin assembly 9 includes: a pin 13 and a second spring 14; wherein, Each mounting base 1 or 2 is horizontally perforated with a movable T-shaped pin 13, and the bottom end of each pin 13 located between two mounting bases 1 or 2 is vertically fixed with a support plate, and a second spring 14 is horizontally fixed between each mounting base 1 or 2 and the support plate.

[0028] In the above scheme, during use, when the actuator 7 is in a horizontal state, the two pins 13 of the pair of first pin assemblies 8 and the pair of second pin assemblies 9, under the tension of the second spring 14, can be inserted into the first locking hole 10 and the second locking hole 11 on both sides of their respective actuator 7, thereby locking the actuator 7 in the horizontal state. This prevents the actuator 7 from moving and causing the valve stem 5 to rise or fall. In other words, it indirectly locks the valve stem 5 and valve plate 3 after they have risen or fallen.

[0029] When the actuator 7 is in a vertical position, the two pins 13 of the pair of first pin assemblies 8 are inserted into the second locking holes 11 on both sides of the actuator 7 under the action of the second spring 14, thereby locking the actuator 7 in the vertical position and preventing the actuator 7 from moving and causing the valve stem 5 to rise or fall. That is, it indirectly locks the valve stem 5 and valve plate 3 after they have risen or fallen.

[0030] In a preferred embodiment of this utility model, a support rod is horizontally rotatably provided at the top of the n-shaped actuator 7, and a through hole is provided at the top of the valve stem 5 for the support rod to pass through. A guide hole is vertically provided at the top of the housing 4 for the valve stem 5 to pass through.

[0031] In the above scheme, the top of the valve stem 5 extends vertically through the guide hole at the top of the housing 4 and is movably mounted on the support rod inside the actuator 7 through the through hole. This allows the actuator 7 to rotate from a horizontal to a vertical state, thereby driving the valve stem 5 to rise vertically and move the valve plate 3 from inside the gate valve body 2 into the housing 4. During the upward movement, the first spring 6 is compressed, thereby connecting the discharge pipe 1 with the inside of the gate valve body 2, so that the liquid in the storage tank of the kitchen cart can be discharged through the discharge pipe 1.

[0032] Conversely, when the actuator 7 flips from a vertical to a horizontal position and abuts against the top of the housing 1, under the force of the first spring 6, the valve stem 5 pushes the guide block, causing the valve plate 3 to descend vertically until the bottom end of the valve plate 3 abuts against the inner wall of the gate valve body 2, thereby isolating the interior of the gate valve body 2 from the discharge pipe 1 and sealing the discharge pipe 1. Furthermore, when the bottom end of the valve plate 3 abuts against the inner wall of the gate valve body 2, the first spring 6 remains tensioned, and under the tension of the first spring 6, the valve plate 3 is tightly pressed against the inner wall of the gate valve body 1.

[0033] In a preferred embodiment of the present invention, the top spaced portion of the housing 4 is recessed inward to form two limiting grooves 12 that cooperate with the bottom ends of the two side walls of the actuator 7.

[0034] In the above scheme, when the actuator 7 is flipped from a horizontal state to a vertical state, the bottom ends of the two side walls of the actuator 7 are placed in the two limiting grooves 12 to limit the actuator 7. In conjunction with the use of the first pin assembly 8, the vertical actuator 7 can be fixed.

[0035] In a preferred embodiment of this utility model, a sealing gasket is horizontally fixed at the bottom end of the guide block.

[0036] In the above scheme, the edge of the sealing gasket abuts against the inner wall of the housing 4 to play a sealing role, so that when the valve stem 5 drives the valve plate 3 to rise and fall, the liquid in the discharge pipe 1 is prevented from entering the housing 4 through the guide block and then overflowing from the top of the housing 4.

[0037] In summary, the gate valve device for the discharge port of the catering cart provided by this utility model overcomes the problem that the existing technology generally relies on the rotation of a screw to move the gate plate and control the opening and closing. During long-term use, the surface of the screw becomes rusty, and the rusty screw is difficult to rotate, resulting in a relatively laborious process of rotating the screw to drive the valve plate to rise and fall.

[0038] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0040] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
