Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and particularly to a strength detection device for a valve housing. Background Art

[0002] A valve is a device for controlling the liquid flow rate, which plays roles such as truncation, regulation, and shunt. The valve housing is a protective device outside the valve, which can be connected to other devices for installation. When the valve housing is produced and processed, a detection device is required to detect the compressive strength of the valve housing.

[0003] After retrieval, it is proposed in Chinese patent application No. CN202020863095.0 that a strength detection device for a valve housing includes a support base. A support wall plate is vertically and fixedly connected to the top of the support base. Two sets of vertically symmetrical hydraulic cylinders are fixedly connected through the support wall plate. A connecting block is fixedly connected between the right ends of the telescopic ends of the two hydraulic cylinders. An extrusion block is arranged to the left of the middle of the connecting block. A pressure sensor is installed between the extrusion block and the connecting block. A stop block located directly to the left of the extrusion block is fixedly connected to the middle of the right side wall of the support wall plate. A chute block fixedly connected to the support wall plate is horizontally arranged behind the stop block. In the above prior art, the valve housing is placed in a clamping groove, and then by turning a bolt, the bolt is used to push a pressing plate to clamp the valve housing. Then, the hydraulic cylinder is used to pull the pressing plate to extrude the housing of the valve, so as to detect the compressive strength of the housing.

[0004] In the above prior art, after the valve housing is placed, the bolt is turned to push the pressing plate to clamp the housing. Although this clamping method is relatively convenient, after installation and after the subsequent detection, the operator needs to manually turn the bolt. The manual turning method is likely to reduce the detection efficiency and increase the working intensity of the operator. At the same time, when using the bolt and the pressing plate to clamp the upper and lower ends of the valve housing, and the hydraulic cylinder pushes the pressing block to extrude the housing from the side for strength detection, the housing deforms under pressure and disengages from the clamping, resulting in the housing falling off, thereby affecting the strength detection effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a strength detection device for a valve housing, which solves the problem that the strength detection device for a valve housing in the prior art is inconvenient for quickly and stably clamping and positioning the valve body, thus affecting the detection efficiency and effect.

A protective component is fixedly connected to the lower side of one end of the extrusion component.

[0007] As a preference of the above technical solution, the pressure measurement component includes a pressure sensor fixedly connected to the inner side of the middle end of the base, and a positioning groove fixedly connected to the middle of the upper side of the pressure sensor.

[0008] As a preference of the above technical solution, the observation component includes a fixing frame fixedly connected to the upper side of one end of the base, and a transparent protective cover fixedly connected to the inner side of the fixing frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] As Figure 1 - Figure 4 shown, the present invention provides a technical solution: a strength detection device for a valve housing, including a base 1, a pressure measurement component is fixedly connected to the inner side of the middle end of the base 1, and an observation component is fixedly connected to the upper side of one end of the base 1. Clamping components are fixedly connected to the outer sides of both ends of the base 1, and an extrusion component is fixedly connected to one end of the base 1 away from the observation component. A protective component is fixedly connected to the lower side of one end of the extrusion component. When performing strength detection on the valve housing, first place the valve housing on the pressure measurement component, then clamp the valve housing through the clamping components, and then start the extrusion component to drive the protective component to move downward. Exert pressure on the valve housing through the extrusion component. At the same time, use the protective component, clamping components and observation components to form protection, and then use the observation component to check the pressure-bearing condition of the housing. In this way, when the detection device detects the valve housing, it can quickly clamp and position the valve housing, and at the same time avoid the housing slipping out of the clamp during the pressure extrusion process, thereby improving the detection stability.

[0021] As Figure 1 and Figure 2 shown, the pressure measurement component includes a pressure sensor 2 fixedly connected to the inner side of the middle end of the base 1, and a positioning groove 21 is fixedly connected to the middle end of the upper side of the pressure sensor 2. The pressure sensor 2 is used to detect the magnitude of the pressure received by the housing, which is convenient for subsequent recording and observation.

[0022] It should be noted that the model of the pressure sensor 2 is MPX50. The working principle is that when pressure acts on the sensitive element of the sensor, the resistance value of the sensitive element will change, and the magnitude of the pressure applied to the sensor is calculated by measuring the change in the resistance value.

[0023] As Figure 1 andFigure 3 As shown, the observation component includes a fixing frame 3 fixedly connected to the upper side of one end of the base 1, and a transparent protective cover 31 is fixedly connected inside the fixing frame 3. The pressure condition of the housing can be viewed through the transparent protective cover 31.

[0024] As Figure 1 shown, the clamping component includes fixing plates 4 fixedly connected to the outer sides of both ends of the base 1, and a hydraulic rod 41 is fixedly connected to the upper ends of the fixing plates 4. One end of the hydraulic rod 41 away from the fixing plate 4 is fixedly connected to a push plate 42. By starting the hydraulic rod 41 supported by the fixing plates 4, after the hydraulic rod 41 is started, it pushes the push plate 42 to clamp and fix both sides of the housing, and the housing can be fixed quickly without manual clamping.

[0025] As Figure 1 shown, the extrusion component includes a support frame 5 fixedly connected to the outer side of one end of the base 1 away from the fixing frame 3, and a hydraulic cylinder 51 is fixedly connected to the lower side of the upper end of the support frame 5. The lower end of the hydraulic cylinder 51 is fixedly connected to a pressing plate 52. By starting the hydraulic cylinder 51 supported by the support frame 5, after the hydraulic cylinder 51 is started, it pushes the pressing plate 52 to move downward.

[0026] As Figure 3 shown, the protection component includes a first baffle 6 fixedly connected to the lower side of one end of the pressing plate 52, and a spring 61 is fixedly connected inside the first baffle 6. The lower end of the spring 61 is fixedly connected to a second baffle 62. When the pressing plate 52 moves downward, it drives the first baffle 6 and the second baffle 62 to move downward synchronously. When the lower side of the second baffle 62 fits with the base 1, at this time, the base 1 reversely pushes the second baffle 62 to be inserted into the first baffle 6 to compress the spring 61, so as to form a protection area by using the fixing frame 3, the transparent protective cover 31, the push plate 42, the first baffle 6 and the second baffle 62.

[0027] Working principle: When performing strength detection on the valve housing, first place the housing on the positioning groove 21 for pre-positioning. Subsequently, start the hydraulic rod 41 under the support of the fixed plate 4. After the hydraulic rod 41 starts, it pushes the push plate 42 to clamp and fix both sides of the housing. Then, start the hydraulic cylinder 51 under the support of the support frame 5. After the hydraulic cylinder 51 starts, it pushes the pressing plate 52 to move downward. While the pressing plate 52 moves downward, it drives the first baffle 6 and the second baffle 62 to move downward synchronously. When the lower side of the second baffle 62 fits with the base 1, at this time, the base 1 reversely pushes the second baffle 62 to be inserted into the first baffle 6 to compress the spring 61. Use the fixing frame 3, the transparent protective cover 31, the push plate 42, the first baffle 6 and the second baffle 62 to form a protection area. Subsequently, the pressing plate 52 continues to move downward to squeeze the housing. After the housing is stressed, the pressure sensor 2 detects the strength of the stress. After the pressure sensor 2 detects, it converts the detection result into a signal and transmits it to the computer through the transmitter and the converter. And the operator can observe the deformation generated by the housing under pressure through the transparent protective cover 31. After the detection is completed, start the hydraulic cylinder 51 to drive the pressing plate 52 and the first baffle 6 etc. to move upward. During the upward movement of the first baffle 6, the spring 61 pushes the second baffle 62 to return due to elastic potential energy. After the pressing plate 52 returns, start the hydraulic rod 41 to drive the push plate 42 to return. Then, take out the detected housing.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
