Description

Technical Field

[0001] The utility model relates to the technical field of valve devices, in particular to a phosphorus removal pump inlet valve which is convenient to replace. Background Technique

[0002] Steel is oxidized at high temperature, and a dense layer of scale (phosphorus scale) is formed on its surface. When strip steel needs to be pickled, the scale will increase the difficulty of pickling and increase the acid consumption. Therefore, before steel billet rolling, the scale on the surface must be removed. The method of using the mechanical impact force of a high-pressure water descaling pump to remove the scale (high-pressure water descaling) is the most common and effective method.

[0003] When installing a descaling pump, an inlet valve is connected to the inlet end to control the inflow and outflow of liquid. Generally, the connection is made through a flange. After using for a period of time, it is necessary to maintain the descaling pump and the inlet valve and remove residual impurities such as scale inside. However, after the flange is tightly fitted for a long time, the two will adhere to each other, achieving an effect similar to cold welding, and it is difficult to remove.

[0004] Therefore, a phosphorus removal pump inlet valve which is convenient to replace is provided to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a phosphorus removal pump inlet valve which is convenient to replace to solve the problems raised in the above background technique.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A phosphorus removal pump inlet valve which is convenient to replace, including a valve body, connection ports are arranged at both ends of the valve body, and further includes:

[0008] An empty slot, arranged on the connection port;

[0009] A rotating rod, rotatably connected in the empty slot;

[0010] A trapezoidal abutting block, fixedly connected to the rotating rod, and the trapezoidal abutting block is used to abut against the pipe orifice of the connection port when the rotating rod rotates, so as to separate the two by means of pressing.

[0011] Preferably, in order to increase the length and facilitate separation, a threaded groove is arranged on the rotating rod, and a first extension rod is threadedly connected to the threaded groove.

[0012] Preferably, in order to further increase the length, a second extension rod is rotatably connected to the first extension rod.

[0013] Preferably, in order to facilitate placement, a magnet is connected to one end of the second extension rod away from the first extension rod.

[0014] For easy storage, preferably, a threaded hole matching the threaded end of the first extension rod is provided at the bottom of the interface.

[0015] Compared with the prior art, the present utility model provides a phosphorus removal pump inlet valve that is easy to replace, and has the following beneficial effects:

[0016] Through the setting of the rotating rod and the trapezoidal abutting block, the present utility model can quickly separate the connection port of the valve body from other pipelines in a lever prying manner, without the need to use additional tools and without affecting the normal use of the valve body.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Embodiment 1:

[0023] Referring to Figures 1 - 3 , the phosphorus removal pump inlet valve that is easy to replace includes a valve body 1, connection ports 101 are provided at both ends of the valve body 1, and further includes: an empty slot 102 provided on the connection port 101; a rotating rod 2 rotatably connected in the empty slot 102; a trapezoidal abutting block 201 fixedly connected to the rotating rod 2, and the trapezoidal abutting block 201 is used to abut against the pipe orifice of the connection port 101 when the rotating rod 2 rotates, and separate the two by means of pressing.

[0024] When the device is in use, the empty hole on the connection port 101 cooperates with the bolt to install the device on the liquid inlet end of the descaling pump and connect it to the liquid supply pipe. When in use, the flow of liquid is controlled by the liquid inlet valve.

[0025] After using it for a period of time, when maintenance is needed, the bolts can be removed. If the two are not tightly adhered, they can be directly disassembled. If the two are tightly adhered, the rotating rod 2 can be rotated to press the trapezoidal block 201 against the flange to create a certain gap between the two. At this time, the two can be separated through this gap, and the separation of the two can be quickly achieved.

[0026] Embodiment 2:

[0027] Reference Figures 1 - 3 The dephosphorization pump inlet valve which is easy to replace is basically the same as that of Example 1, and furthermore: a threaded groove is provided on the rotating rod 2, an extension rod 1 301 is threadedly connected to the threaded groove, and an extension rod 2 302 is rotatably connected to the extension rod 1 301.

[0028] By extending rod one 301 and rod two 302, the rotational torque of rotating rod 2 can be increased, thereby increasing the squeezing force of trapezoidal stop block 201 on the flange, thereby promoting the rapid separation of the two. When using, it is necessary to pay attention to the rotation position of extension rod two 302, and rotate rotating rod 2 in the opposite direction where extension rod two 302 cannot rotate.

[0029] Embodiment 3:

[0030] Reference Figures 1 - 3 The dephosphorization pump inlet valve which is easy to replace is basically the same as that in Example 1, and furthermore: a magnet 303 is connected to one end of the extension rod 2 302 away from the extension rod 1 301, and a threaded hole matching the threaded end of the extension rod 1 301 is provided at the bottom of the connection port 101.

[0031] By setting the threaded hole and the magnet 303, as Figure 1 As shown, the extension rod 1 301 is rotated into the threaded hole, and the magnet 303 is adsorbed on the bottom of the valve body 1, so that the extension rod 1 301 and the extension rod 2 302 form an L shape, which is convenient for storage and reduces space occupation.

[0032] The utility model can quickly separate the connection port 101 of the valve body 1 from other pipelines by means of a pry bar through the arrangement of the rotating rod 2 and the trapezoidal stop block 201, without using additional tools and without affecting the normal use of the valve body 1.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
