Description

Technical Field

[0001] The utility model relates to the technical field of valve testing, in particular to a valve durability and moisture resistance testing system. Background Art

[0002] The Valve Durability and Humidity Resistance Test System is a device specifically designed to test the performance stability and humidity resistance of valves over long-term use. It simulates the various pressure, temperature, and flow rate fluctuations, as well as the frequent opening and closing operations that valves may encounter in actual operating environments, thereby testing the durability and reliability of valves.

[0003] Conventional valve durability and moisture resistance test systems use special reagents to detect the aging resistance of the valve body when testing the valve body. At the same time, a certain amount of reagents will be used during the test process, which makes the test cost higher.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a valve durability and moisture resistance testing system is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a valve durability and moisture resistance testing system to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve durability and moisture resistance testing system, comprising a protective frame and a circulation component, a test component is installed in the middle of the protective frame, the circulation component is installed on the side of the test component, and an exhaust component is installed on the rear facade of the test component, the circulation component comprises a liquid storage tank, a micro reflux pump, a liquid extraction pipe, a liquid injection port, a connecting pipe and a spray rack, the bottom of the liquid storage tank is connected to the micro reflux pump, and the liquid extraction pipe is installed at the end of the micro reflux pump away from the liquid storage tank, and the liquid injection port is provided on one side of the top of the liquid storage tank, and a connecting pipe is installed in the middle of the top of the liquid storage tank, and the end of the connecting pipe away from the liquid storage tank is connected to the spray rack.

[0007] Furthermore, the protective frame includes a stabilizing seat, an elastic telescopic column and a buffer baffle. Stabilizing seats are vertically installed on both the left and right sides of the stabilizing seat, and the top of the stabilizing seat is connected to the buffer baffle.

[0008] Furthermore, the buffer baffle is horizontally mounted directly above the stabilizing seat, and the elastic telescopic column is symmetrically installed on one side of the stabilizing seat.

[0009] Furthermore, the test assembly includes an environmental simulation test box, a box door, a turntable, a slot and a partition. The box door is installed on the front facade of the environmental simulation test box, and a turntable is installed inside the environmental simulation test box. A slot is opened on the bottom surface of one side of the opening of the environmental simulation test box, and a partition is inserted inside the slot.

[0010] Furthermore, the partition is horizontally inserted on one side between the environmental simulation test box and the box door, and the turntable is installed in the middle of the bottom side inside the environmental simulation test box.

[0011] Furthermore, the end of the liquid extraction pipe away from the micro reflux pump is arranged toward the bottom side of the environmental simulation test box, and the spray rack passes through the top of the environmental simulation test box and makes the output end vertically face the middle of the interior of the environmental simulation test box.

[0012] Furthermore, the exhaust assembly includes a fan body, a protective net and a filter plate. Protective nets are installed on both the front and rear sides of the fan body, and a filter plate is installed on the side of the protective net close to the inside of the fan body.

[0013] Furthermore, the exhaust assembly is fixed to the rear side of the test assembly and is interconnected with the interior of the test assembly, and the filter plate is arranged on both the front and rear sides of the interior of the fan body.

[0014] The utility model provides a valve durability and moisture resistance testing system, which has the following beneficial effects:

[0015] 1. The present invention installs a circulation assembly on the side of the test assembly. When the aging agent or liquid for increasing humidity required for the test is injected into the liquid storage tank through the liquid injection port, it is transported by the connecting pipe and atomized and sprayed from the output end of the spray rack into the interior of the environmental simulation test chamber, thereby performing a humidity resistance test on the pump body. At the same time, the sprayed atomized liquid gradually falls to the bottom side of the environmental simulation test chamber. Because the partition is inserted into the side near the chamber door using a slot, this structure forms a receiving tray structure on the bottom of the environmental simulation test chamber, and collects the falling atomized liquid. Under the operation of the micro reflux pump, the collected liquid is extracted by the liquid extraction pipe and returned to the interior of the liquid storage tank. The use of the above structure can, on the one hand, realize different testing operations by main-loading different liquids in the liquid storage tank according to the test needs, thereby ensuring the flexibility of the device. On the other hand, the operation of the above structure can realize the real-time reflux collection of the atomized sprayed liquid, thereby realizing the recycling of the liquid used for the test, thereby effectively controlling the testing cost and avoiding material waste.

[0016] 2. The utility model provides a protective frame on the outside of the test assembly, utilizes the elastic telescopic columns on both sides of the stabilizing seat, and cooperates with the filter plate connected horizontally on the top thereof. When a falling object or an external collision comes into contact with the buffer baffle, the buffer baffle will absorb kinetic energy. At the same time, the elastic telescopic columns connected thereto will also undergo structural expansion and contraction due to the external force, thereby achieving a buffering structural effect. By using the above structure, the structural protection of the test assembly can be effectively achieved, avoiding unnecessary influence and interference on the pump body under test. The exhaust assembly installed on the rear side of the test assembly will discharge the moisture inside the test assembly as quickly as possible under the operation of the fan body. At the same time, under the action of the filter plate, the gas inside the test assembly can be quickly and effectively filtered and then discharged, so as to reduce the impact on the external environment.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 3As shown, a valve durability and moisture resistance test system includes a protective frame 1 and a circulation component 3, a test component 2 is installed in the middle of the protective frame 1, the circulation component 3 is installed on the side of the test component 2, and an exhaust component 4 is installed on the rear elevation of the test component 2, the circulation component 3 includes a liquid storage tank 301, a micro reflux pump 302, a liquid extraction pipe 303, a liquid injection port 304, a connecting pipe 305 and a spray rack 306, the bottom of the liquid storage tank 301 is connected to the micro reflux pump 302, and the end of the micro reflux pump 302 away from the liquid storage tank 301 is installed with a liquid extraction pipe 303, and a liquid injection port 304 is provided on one side of the top of the liquid storage tank 301, and a connecting pipe 305 is installed in the middle of the top of the liquid storage tank 301, and the end of the connecting pipe 305 away from the liquid storage tank 301 A spray rack 306 is connected, and the end of the liquid extraction pipe 303 away from the micro reflux pump 302 is set toward the bottom side of the interior of the environmental simulation test box 201. The spray rack 306 runs through the top of the environmental simulation test box 201 and has the output end vertically facing the middle of the interior of the environmental simulation test box 201. The atomized liquid sprayed by the spray rack 306 will gradually fall to the bottom side of the interior of the environmental simulation test box 201. Since the partition 205 is inserted into the side close to the box door 202 using the slot 204, this structure forms a receiving tray structure at the bottom of the interior of the environmental simulation test box 201, and the falling and gathered atomized liquid is collected in a centralized manner, so that under the operation of the micro reflux pump 302, the gathered liquid can be extracted using the liquid extraction pipe 303 and returned to the interior of the liquid storage tank 301.

[0023] like Figures 1 to 3As shown, the protective frame 1 includes a stable seat 101, an elastic telescopic column 102 and a buffer baffle 103. The stable seat 101 is vertically installed on both sides of the left and right sides of the stable seat 101, and the top of the stable seat 101 is connected to the buffer baffle 103. The buffer baffle 103 is horizontally mounted directly above the stable seat 101, and the elastic telescopic column 102 is symmetrically installed on one side of the stable seat 101 front and back. The test component 2 includes an environmental simulation test box 201, a box door 202, a turntable 203, a slot 204 and a partition 205. The front side facade of the environmental simulation test box 201 is installed with a box door 202, and the interior of the environmental simulation test box 201 is installed with a turntable 203, and a slot 204 is opened on the bottom surface of one side of the opening of the environmental simulation test box 201, and a partition 205 is inserted inside the slot 204.

The front and rear sides of the fan body 401 are both equipped with protective nets 402, and the side of the protective net 402 close to the inside of the fan body 401 is equipped with a filter plate 403. The exhaust component 4 is fixed to the rear side of the test component 2 and is interconnected with the inside of the test component 2. The filter plate 403 is arranged on both sides of the inside of the fan body 401, and the elastic telescopic columns 102 on both sides of the stabilizing seat 101 are used, and the filter plate 403 connected horizontally to the top thereof is used. When a falling object or an external collision contacts the buffer baffle 103, kinetic energy will be absorbed under the action of the buffer baffle 103, and the elastic telescopic column 102 connected thereto will also undergo structural expansion and contraction due to the external force, thereby achieving a buffering structural effect.

[0024] In summary, if Figures 1 to 3 As shown, when using the valve durability and humidity resistance test system, first place the pump body to be tested on the surface of the turntable 203 inside the environmental simulation test box 201, and vertically insert the partition 205 into the slot 204, and then close the box door 202;

[0025] The reagents required for the test are then injected into the liquid storage tank 301 through the liquid injection port 304. The reagents are then transported through the connecting pipe 305 to the interconnected spray rack 306 inside the environmental simulation test chamber 201. The spray rack 306 operates to atomize the test reagents and spray them onto the surface of the pump body. The atomized liquid sprayed from the spray rack 306 gradually falls to the bottom of the environmental simulation test chamber 201. The micro reflux pump 302 operates to extract the collected liquid through the liquid extraction pipe 303 and return it to the liquid storage tank 301. Simultaneously, the environmental simulation test chamber 201 operates synchronously to simulate the durability and moisture resistance testing environment of the valve body until the test is completed.

[0026] During the test, the protective frame 1 outside the test component 2 will come into play. When there is a collision and structural contact with the buffer baffle 103, the structural characteristics of the elastic telescopic columns 102 vertically installed on both sides of the stabilizing seat 101 can provide a certain degree of structural protection for the test component 2. After the pump body test is completed, the exhaust component 4 on the rear side of the test component 2 will quickly discharge the moisture inside the test component 2 under the operation of the fan body 401, and filter the moisture under the action of the filter plate 403 to avoid affecting the external environment.
