[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves come in a wide variety of varieties and specifications and are widely used. For example, valves need to be installed to control the flow of oil during transportation. At present, in order to prevent the valve from being blocked by foreign matter, some pipeline transportation or development valves on the market usually have a filter at the mouth of the valve to intercept impurities in the oil. However, this filter has the following defects when used: impurities easily accumulate on the filter, causing the filter to be quickly blocked, affecting the filtering effect and service life of the filter, and requiring frequent opening of the sealing cover to remove the net and pour out the impurities. The operation is cumbersome and affects work efficiency. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 It is given, including a rectangular main body shell 1, with conveying pipes 2 respectively provided on the upper and lower sides of the main body shell 1, a plurality of support rods 3 located between the two conveying pipes 2 and evenly distributed along the left and right directions are slidably connected in the main body shell 1, a rectangular support plate 4 is provided between every two support rods 3, and a filter screen 5 is provided on the support plate 4 in an upper and lower axial direction, and the distance between the upper and lower ends of the filter screen 5 is smaller than the distance between the upper and lower ends of the support rods 3, sealing blocks 6 that can contact with the support plate 4 are respectively provided on the left and right sides of the main body shell 1, and knocking columns 7 that can move up and down are respectively provided on the left and right sides of the upper end of the main body shell 1, and a plurality of knocking balls 8 that can contact with the filter screen 5 are provided at the lower end of the knocking column 7.

[0016] In order to move the filter screen 5 , a push column 9 slidably connected to the main body shell 1 is provided at the left end of the leftmost support rod 3 .

[0017] For ease of use, the striking ball 8 is positioned above the support rod 3 when stationary.

[0018] To facilitate the up and down movement of the knocking column 7, the knocking column 7 is slidably connected to the main body shell 1. A pulling plate 10 is provided at the upper end of the knocking column 7, and a spring 11 is sleeved on the knocking column 7 and located between the pulling plate 10 and the main body shell 1.

[0019] To ensure the sealing effect, the sealing block 6 is made of rubber material.

[0020] To facilitate the collection of impurities, funnel-shaped collection cylinders 12 are respectively provided on the left and right sides inside the main body shell 1 and located below the support rods 3. The lower ends of the collection cylinders 12 penetrate through the main body shell 1 and are threadedly connected with collection boxes 13.

[0021] When the present utility model is in use, first, the lower conveying pipe 2 is connected to the petroleum transportation pipe, and the upper conveying pipe 2 is connected to the valve. At this time, petroleum is conveyed from the lower conveying pipe 2 into the main body shell 1. At this time, due to the sealing between the sealing block 6 and the support plate 4, the petroleum will not flow to the left and right sides. Instead, it flows upward through the right filter screen 5 into the upper conveying pipe 2 and then into the valve. At this time, the right filter screen 5 filters the impurities in the petroleum to prevent the valve from being worn. When the impurities on the right filter screen 5 are too many and the filtering effect is not good after using for a period of time, at this time, the conveying pump is turned off, and the push column 9 is pushed to the right. The push column 9 drives the plurality of support rods 3 and the two filter screens 5 to move to the right. After moving a certain distance to the right, the blocked filter screen 5 moves to the right side inside the main body shell 1. At the same time, the unused filter screen 5 originally on the left moves to the right to communicate with the two conveying pipes 2. At this time, the support rods 3 contact the sealing block 6 again and achieve sealing;

[0022] At this time, the conveying pump is turned on, and petroleum enters the main body shell 1 from the conveying pipe 2 again and is filtered again through the filter screen 5. At this time, the filter screen 5 that was originally full of impurities and blocked is located on the right side inside the main body shell 1. At this time, the right pulling plate 10 is pulled upward. The right pulling plate 10 drives the right knocking ball 8 to move upward. After moving a certain distance upward, the pulling plate 10 is released. Due to the downward restoring force of the spring 11, the knocking ball 8 moves downward. Due to the elastic force of the spring 11, after the knocking ball 8 moves downward a certain distance, it contacts the right filter screen 5 and knocks the right filter screen 5. Repeating this several times can knock off the impurities on the right filter screen 5, and the impurities fall into the collection cylinder 12 and are stored in the collection box 13;

[0023] When the left filter screen 5 is blocked after using for a period of time again, at this time, the push column 9 is pulled back to the left, driving the two filter screens 5 to move to the initial position. At this time, the filter screen 5 that has been knocked and cleaned is located between the two conveying pipes 2 again, and the blocked filter screen 5 is located on the left. At this time, the left pulling plate 10 is pulled upward to make the knocking ball 8 knock and clean the left filter screen 5. After using for a period of time, the collection box 13 is unscrewed from the lower end of the collection cylinder 12, the impurities inside are cleaned, and then it is screwed back on.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows: The provided filter screen, knocking balls, collection cylinder, etc. can filter the petroleum before it enters the valve, prevent impurities therein from entering the valve and damaging the valve. At the same time, the clogged filter screen can be quickly cleaned and restored. Compared with the traditional method of disassembling the valve to replace the filter screen, the operation is simple, time-saving and labor-saving. This structure is simple, novel in conception, convenient to use and has strong practicability.

[0025] It should be noted that according to the needs of implementation, each component described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0026] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
