Description

Technical Field

[0001] The utility model belongs to the technical field of valve parts, and particularly relates to a valve body convenient for assembly. Background Art

[0002] In automobiles and various mechanical equipment, valves play a crucial role in controlling the flow rate and direction of fluids. These valves include, but are not limited to, gas valves, cooling water valves, exhaust valves, etc. The valve body is the outer shell of the valve, which undertakes the function of accommodating important components such as actuators, valve cores, and valve stems. The valve body with an internal actuator can precisely adjust the valve core and is suitable for scenarios that require precise control of fluid flow. Such valve bodies also have an assembly base in some designs, which can be stably fixed to other mechanical structures through the base, thereby improving the reliability and durability of the entire system.

[0003] However, such valve bodies also have some deficiencies in actual applications. When the valve body base is connected to other mechanical structures, the limit parts on the valve body sometimes make the positioning and assembly process complicated and inconvenient. If the valve body is not aligned and the installation angle of the valve body is not adjusted properly, there will be difficulties in docking the limit parts with the mechanical structure. It is difficult to quickly install the valve body base of this valve body onto the corresponding mechanical structure, which may also affect the maintenance convenience of the entire system. Therefore, how to design a valve body that can both meet the limiting function and does not bring additional difficulties to the assembly process is of great significance for improving the valve body assembly efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a valve body convenient for assembly to improve the valve installation efficiency in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A valve body convenient for assembly, which includes a base and a valve core fitting fixedly arranged on one side outside the base. An actuator fitting is fixedly arranged on the other side outside the base, and a limit part and a guiding part protrude outward from the inside of the base. The guiding part is used to align the base on the assembly structure so that the limit part can be docked with the assembly structure. When assembling the valve body, the base is moved towards the assembly structure, and the guiding part first embeds into the assembly structure. When the guiding part embeds into the assembly structure, the alignment of the base can be achieved. In this state, the position and angle of the base can ensure that when the valve body is pushed, the limit part can be docked with the assembly structure to complete the positioning of the valve body on the assembly structure.

[0007] As a further optimized solution of the utility model, the guiding part includes a positioning seat fixedly arranged on the inner wall of the base, and a guiding head is fixedly arranged on one side of the positioning seat. The cross-sectional area of the guiding head is smaller than that of the positioning seat.

[0008] As a further optimized solution of the present utility model, the guiding head has a V-shaped side wall.

[0009] As a further optimized solution of the present utility model, a number of assembly holes corresponding to the assembly structure are provided at the edge of the base.

[0010] As a further optimized solution of the present utility model, the limiting member is divided into a limiting cylinder and a limiting plate. The limiting cylinder is arranged close to the actuator fitting, and both the limiting plate and the guiding member are arranged close to the spool regulator chamber. At least two limiting cylinders are provided.

[0011] As a further optimized solution of the present utility model, the limiting member is divided into a limiting cylinder and a limiting plate. The limiting cylinder is arranged close to the actuator fitting, and the limiting plate is arranged close to the spool regulator chamber.

[0012] As a further optimized solution of the present utility model, a reinforcing rib is fixedly provided between the actuator fitting and the spool fitting, and a plurality of flange connection columns are fixedly provided on the outer wall of the spool fitting.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1) When assembling the valve body of the present utility model, the base is moved towards the assembly structure, and the guiding member is first inserted into the assembly structure. At this time, the base is aligned. The position and angle of the base can ensure that when the valve body is pushed, the limiting member can be docked with the assembly structure, thereby realizing the rapid positioning of the valve body and facilitating the subsequent operation of fastening the valve body to the assembly structure;

[0015] 2) The guiding member of the present utility model is composed of a positioning seat and a guiding head. Grooves and slots corresponding to the positioning seat and the guiding head are provided in the assembly seat on the assembly structure. The cross-sectional area of the guiding head is small, which is convenient for being stuck into the groove. Slightly swinging the base can make the guiding head slide along the groove to the slot, and when the guiding head is inserted into the slot, the alignment of the base can be completed, further improving the convenience of assembling the valve body;

[0016] 3) Before connecting the pipelines to the joints at both ends of the spool fitting of the present utility model, the valve body is also fixed by the base. The two limiting cylinders on one side of the valve body can position the actuator fitting, and the guiding member and the limiting plate on the other side of the valve body can position the spool fitting, making the assembled valve body more reliable and helping to improve the flow control accuracy of the valve.

[0024] Embodiment

[0025] As Figure 1 and Figure 2 shown, a valve body convenient for assembly is installed on an assembly structure. The valve body includes a base 1 and a spool fitting 2 fixedly arranged on one side outside the base 1. An actuator fitting 3 is fixedly arranged on the other side outside the base 1. Moreover, a limiting part 4 and a guiding part 5 protrude outward from the inside of the base 1. Both the limiting part 4 and the guiding part 5 are arranged downward. In this embodiment, the setting direction of the valve body structure takes Figure 1 as the reference datum. The base 1 of the valve body is placed horizontally as a whole. The guiding part 5 is used to align the base 1 on the assembly structure so that the limiting part 4 can be docked with the assembly structure. When assembling the valve body, move the base 1 towards the assembly structure. The guiding part 5 first embeds into the assembly structure. When the guiding part 5 embeds into the assembly structure, the alignment of the base 1 can be realized. In this state, the position and angle of the base 1 can ensure that when the valve body is pushed, the limiting part 4 can be docked with the assembly structure, thereby realizing the rapid positioning of the valve body and facilitating the subsequent operation of fastening the valve body to the assembly structure.

[0026] Specifically, as Figures 2 - 5As shown in the figure, the guide member 5 includes a positioning seat 51 fixedly provided at the top of the inner wall of the base 1. A guide head 52 is fixedly provided on the lower side of the positioning seat 51. The cross-sectional area of the guide head 52 is smaller than that of the positioning seat 51. The guide head 52 has a V-shaped side wall 53. The limiting member 4 is divided into a limiting cylinder 41 and a limiting plate 42. The limiting cylinder 41 is arranged close to the actuator fitting 3. Both the guide head 52 and the limiting plate 42 are arc-shaped. The guide head 52 is also arc-shaped and bent. And both the limiting plate 42 and the guide member 5 are arranged close to the valve core regulator chamber 7. At least two limiting cylinders 41 are provided. The assembly structure is an assembly plate 9. An assembly seat 91 corresponding to the guide member 5 is provided at the top of the assembly plate 9. An arc-shaped groove 92 corresponding to the shape of the positioning seat 51 is opened on the assembly seat 91. A slot 93 is opened downward at the bottom of the groove 92. The shape of the slot 93 corresponds to that of the guide head 52. A limiting post 94 corresponding to the limiting cylinder 41 and a limiting seat 95 corresponding to the limiting plate 42 are also provided on the assembly plate 9. A limiting groove 96 is opened on the limiting seat 95. The shape of the limiting groove 96 is the same as that of the limiting plate 42.

[0027] When moving the base 1 towards the assembly plate 9, the guide head 52 first enters the groove 92. Slightly swinging the base 1 can make the guide head 52 slide along the groove 92 into the slot 93. After the guide head 52 is embedded in the slot 93, the limiting post 94 starts to be embedded into the limiting cylinder 41, and the limiting plate 42 also starts to be clamped into the limiting groove 96 on the limiting seat 95. The action of embedding the guide head 52 into the slot 93 makes the limiting cylinder 41 and the limiting plate 42 of the valve body complete the alignment simultaneously, further improving the convenience of assembling the valve body. In addition, the V-shaped side wall 53 of the guide head 52 can make the guide body 52 more easily clamped into the groove 92 and the slot 93. A number of assembly holes 6 corresponding to the assembly structure are provided at the edge of the base 1. The number of the assembly holes 6 is preferably five. The assembly holes 6 have internal threads. When the bottom of the base 1 is attached to the assembly plate 9 after alignment, the positioning of the valve body is completed. The valve body and the assembly structure are fastened by a threaded fastener. After the threaded fastener passes through the assembly plate 9 and is screwed into the assembly hole 6, the assembly of the valve body is completed.

[0028] Further, please refer to Figure 3 and Figure 4, a spool regulator chamber 7 is provided between the spool fitting 2 and the base 1, and a transmission shaft mounting hole 8 is provided between the spool regulator chamber 7 and the actuator fitting 3. The actuator fitting 3 can accommodate an actuator, which is preferably a flow motor. The spool regulator chamber 7 is used to install a spool regulator, which has a valve stem fixedly connected to the spool. The flow motor is connected to the valve stem through a transmission structure, which has a transmission shaft installed in the transmission shaft mounting hole 8, and the transmission structure is preferably a gear set. A wiring port corresponding to the flow motor is also provided on the side wall of the base 1. After the above components are installed on the valve body, the flow motor can cooperate with the gear set and the spool regulator to rotate the spool to change the opening degree of the valve, so as to adjust the flow rate of the fluid. When the valve is closed, the valve body will cut off the fluid; when the valve is opened, the valve body will allow the fluid to flow through. The valve body can be used to adjust the pressure of the fluid by changing the opening degree of the valve. When the valve is opened, the pressure of the fluid will decrease; when the valve is closed, the pressure of the fluid will increase. To achieve pressure regulation. The valve body can also be used to control the flow direction of the fluid. The spool can be rotated in time to close the valve to prevent backflow or countercurrent. The fluid temperature can also be adjusted by changing the opening degree of the valve.

[0029] In addition, a reinforcing rib is fixedly provided between the actuator fitting 3 and the spool fitting 2. Pipe joints are provided on both sides of the spool fitting 2. A plurality of flange connection columns are fixedly provided on the outer wall of the spool fitting 2. Connection holes are provided in the flange connection columns. After the base 1 is connected to the assembly plate 9, the valve body can be connected to the relevant flanges through the flange connection columns and bolts to complete the docking of the valve body joint and the pipeline.

[0030] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
