Description

Technical Field

[0001] This utility model belongs to the field of pump and valve housing technology, and particularly relates to a high-temperature resistant pump and valve housing. Background Technology

[0002] Pump and valve housings are an important component of pumps and valves, and are usually made of materials such as cast iron and cast steel to house and protect internal mechanical parts.

[0003] Most pump and valve housings have some drawbacks in use, such as the bolts used to fix the connection between the pump / valve housing and the pipeline. These bolts, when exposed to the elements for extended periods, may rust, making disassembly difficult and time-consuming. Therefore, we propose a high-temperature resistant pump and valve housing. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant pump and valve housing to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a high-temperature resistant pump valve housing, comprising a pump valve housing and two water pipes, and further comprising:

[0006] Two first protective covers are provided at the bottom of the pump valve housing, and a second protective cover is provided at the top of each of the two first protective covers. The two water pipes are respectively fixedly installed at both ends of the pump valve housing.

[0007] Two power chambers are respectively opened in two second protective covers. Two sliding strips are slidably installed in each power chamber. Connecting rods are rotatably installed at both ends of each sliding strip. Limiting posts are rotatably installed at the lower ends of the connecting rods. Two limiting grooves are opened in the first protective cover. The lower ends of the limiting posts penetrate the corresponding power chambers and extend into the corresponding limiting grooves, and the limiting posts are inserted into the corresponding limiting grooves.

[0008] Two sets of drive components are located inside two second protective covers and are used to drive the four sliders to slide.

[0009] In this technical solution, when it is necessary to protect the connection between the pump valve housing and the two water pipes, the pump valve housing and the two water pipes are first connected to each other using tools and bolts. Then, the first protective cover is placed at the connection between the pump valve housing and one of the water pipes. Subsequently, the second protective cover is placed on top of the first protective cover. The inner walls of the two limiting grooves press against the inclined surfaces on the two limiting posts, causing the two limiting posts to slide and move closer to each other. The two limiting posts press against the four connecting rods to rotate, and the four connecting rods press against the two sliding strips to slide upwards. When the first and second protective covers are in close contact, the driving component can drive the two sliding strips to slide downwards. The two sliding strips press against the four connecting rods to rotate, and the four connecting rods drive the two limiting posts to slide and move away from each other, so that the two limiting posts are respectively locked in the two limiting grooves. This fixes the position of the second protective cover and the power chamber, protects the connection between the pump valve housing and the two water pipes, ensures that the bolts are not exposed to the outside, and prevents water from entering the bolts. Through the above reverse operation, the first and second protective covers can be disassembled without the use of tools, making the operation simple.

[0010] In the above technical solution, the driving component further includes:

[0011] A sliding plate is fixedly installed on top of two sliding strips. Several fixed posts are fixedly installed inside the power cavity and on top of the sliding plate. The lower ends of the fixed posts all penetrate the sliding plate and the lower ends of the fixed posts respectively penetrate the two sliding strips. Tension springs are sleeved on the fixed posts.

[0012] In this technical solution, when protection is needed at the connection between the pump valve housing and the two water pipes, the pump valve housing and the two water pipes are first connected to each other using bolts. Then, a first protective cover is placed at the connection between the pump valve housing and one of the water pipes. Next, a second protective cover is placed on top of the first protective cover. The inner walls of the two limiting grooves press against the inclined surfaces on the two limiting posts, causing the two limiting posts to slide and move closer to each other. The two limiting posts press against the four connecting rods, causing them to rotate. The four connecting rods press against the two sliding strips, causing them to slide upwards. The two sliding strips press against the sliding plate and handle, causing them to slide upwards. Simultaneously, several tension springs are stretched. When the first protective cover and the second protective cover are in close contact, under the tension of several springs, the sliding plate and the two sliding strips slide downwards. The two sliding strips squeeze the four connecting rods to rotate, and the four connecting rods drive the two limiting posts to slide and move away from each other, so that the two limiting posts are respectively stuck in the two limiting grooves. This can fix the position of the second protective cover and the power chamber, and protect the connection between the pump valve housing and the two water pipes, ensuring that the bolts are not exposed to the outside and that the bolts are not exposed to water. Through the above reverse operation, the first protective cover and the second protective cover can be disassembled without the use of tools, and the operation is simple.

[0013] In the above technical solution, furthermore, the two ends of the tension spring are fixedly connected to the corresponding sliding bar and the inner wall of the corresponding power cavity, respectively.

[0014] In this technical solution, it is ensured that several tension springs will not bend during use.

[0015] In the above technical solution, furthermore, sealing rubber gaskets are fixedly installed on the side of the second protective cover and the first protective cover that are close to each other. The four sealing rubber gaskets are in close contact with the pump valve housing and the two water pipes respectively, and the second protective cover is in close contact with the corresponding first protective cover.

[0016] In this technical solution, it is ensured that no water droplets will enter the second protective cover and the first protective cover, and that the bolts will not rust.

[0017] In the above technical solution, a handle is further fixedly installed on the top of the sliding plate, the upper end of the handle passes through the power cavity and extends to the outside, and the handle is slidably connected to the power cavity.

[0018] In this technical solution, a handle is provided to facilitate pulling the sliding plate.

[0019] In the above technical solution, the sliding plate and the corresponding two sliding strips are integrally formed.

[0020] In this technical solution, the stability of the sliding plate and the corresponding two sliding bars is ensured during use.

[0021] In the above technical solution, the limiting post and the sliding plate are slidably connected to the corresponding power cavity, and the fixing post is slidably connected to the corresponding sliding plate and the corresponding sliding strip.

[0022] In this technical solution, it is ensured that both the limiting post and the sliding plate can slide within the corresponding power cavity, and that the fixed post can slide within the corresponding sliding plate and the corresponding sliding strip.

[0023] The beneficial effects of this utility model are:

[0024] The high-temperature resistant pump valve housing, through the installation of a first protective cover, a second protective cover, a sliding strip, a connecting rod, a limiting post, a limiting groove, a sliding plate, a fixing post, a tension spring, and a sealing rubber gasket, can protect the connection between the pump valve housing and the two water pipes, ensuring that the bolts are not exposed to the outside and that the bolts are not exposed to water. The first and second protective covers can be disassembled through the above reverse operation without the use of tools, making the operation simple. Attached Figure Description

Connecting rods 7 are rotatably installed at both ends of the sliding strips 6. Limiting posts 8 are rotatably installed at the lower end of the connecting rods 7. Two limiting grooves 9 are opened in the first protective cover 3. The lower end of the limiting post 8 passes through the corresponding power chamber 5 and extends into the corresponding limiting groove 9. The limiting post 8 and the corresponding limiting groove 9 are inserted and matched.

[0042] Two sets of drive components are located inside two second protective covers 4, and are used to drive the four sliding bars 6 to slide.

[0043] When protection is needed at the connection between the pump valve housing 1 and the two water pipes 2, the pump valve housing 1 and the two water pipes 2 are first connected to each other using bolts. Then, the first protective cover 3 is placed at the connection between the pump valve housing 1 and one of the water pipes 2. Next, the second protective cover 4 is placed on top of the first protective cover 3. The inner walls of the two limiting grooves 9 press against the inclined surfaces of the two limiting posts 8, causing the two limiting posts 8 to slide and move closer to each other. The two limiting posts 8 press against the four connecting rods 7 to rotate, and the four connecting rods 7 press against the two sliding strips 6 to slide upwards. When the first protective cover 3 and the second protective cover 4 are tightly connected... Upon contact, the driving component allows the two sliding bars 6 to slide downwards, pressing the four connecting rods 7 to rotate. The four connecting rods 7 then drive the two limiting posts 8 to slide and move away from each other, causing the two limiting posts 8 to be locked in the two limiting grooves 9. This fixes the position of the second protective cover 4 and the power chamber 5, and protects the connection between the pump valve housing 1 and the two water pipes 2, ensuring that the bolts are not exposed to the outside world and that water does not enter the bolts. Through the above reverse operation, the first protective cover 3 and the second protective cover 4 can be disassembled without the use of tools, making the operation simple.

The two limiting posts 8 press against the four connecting rods 7 to rotate. The four connecting rods 7 press against the two sliding strips 6 to slide upward. The two sliding strips 6 press against the sliding plate 10 and the handle 13 to slide upward. At the same time, several tension springs 12 are stretched. When the first protective cover 3 and the second protective cover 4 are in close contact, under the tension of several tension springs 12, the sliding plate 10 and the two sliding strips 6 slide downwards. The two sliding strips 6 respectively squeeze the four connecting rods 7 to rotate. The four connecting rods 7 respectively drive the two limiting posts 8 to slide and move away from each other, so that the two limiting posts 8 are respectively stuck in the two limiting grooves 9. This can fix the position of the second protective cover 4 and the power chamber 5, and protect the connection between the pump valve housing 1 and the two water pipes 2, ensuring that the bolts will not be exposed to the outside world and that the bolts will not be infiltrated by water.
