Technical Field

[0001] The utility model relates to the relevant field of valve turbine heads, in particular to a valve turbine head with dustproof protection. Background Art

[0002] A valve turbine head is a fluid control device used to control the flow of liquid or gas. It usually consists of a turbine and one or more valves. The valve is usually used to control the rotation of the turbine to control the flow and pressure of the fluid. The valve can be electric or manual and can be used for different types of fluid control, including water, air and oil.

[0003] When the valve turbine head is in use, a sealing ring is usually set between the end cover and the main body to prevent external dust from entering the interior. However, the simple sealing ring has a poor dust-proof effect. Especially after the turbine head has been used for a long time, the sealing ring is prone to loosening and aging, which will further affect the dust-proof protection effect of the turbine head. When a large amount of external dust enters the turbine head, it is easy to affect the stability of the operation of the internal parts, reducing the practicability of the turbine head. Summary of the invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a valve turbine head with dustproof protection to solve the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a valve turbine head with dustproof protection, comprising a turbine head, a device body connected to the turbine head, an end cover installed on the upper end of the turbine head, and a protection mechanism arranged in the turbine head, wherein the protection mechanism comprises a sealing outer ring movably inserted into the turbine head, a fitting groove opened on the top of the outer side of the turbine head, and an inclined boss arranged along the circumference of the bottom end surface edge of the end cover and corresponding to the fitting groove;

[0006] A sealing gasket is fixedly installed in the fitting groove and is in close contact with the inner ring of the inclined boss;

[0007] The sealing outer ring is coaxially built with a sealing inner ring, and a spacing is set between the inner ring of the sealing outer ring and the side surface of the sealing inner ring to form a collecting groove for collecting dust and impurities, and a supporting sheet is set at the bottom of the collecting groove, and the inner and outer ends of the supporting sheet are respectively connected to the outer surface of the sealing inner ring and the inner ring of the sealing outer ring.

[0008] Preferably, the inner circle of the inclined boss is tapered from bottom to top, and a corresponding inclined surface is provided on the sealing gasket.

[0009] Preferably, the sealing outer ring is flush with the bottom end surface of the sealing inner ring, and the height of the sealing outer ring is smaller than the height of the sealing inner ring.

[0010] Preferably, a silicone gasket is fixedly mounted on the top end surface of the inner sealing ring, and the silicone gasket and the bottom end surface of the end cover are in close contact with each other.

[0011] Preferably, a positioning groove movably connected to the sealing outer ring, the sealing inner ring and the supporting sheet is provided at the inner bottom edge of the turbine head.

[0012] Preferably, an annular plate is slidably installed in the positioning groove, the annular plate and the bottom end surface of the supporting sheet are in contact with each other, and the annular plate is connected to the inner bottom of the positioning groove through a spring.

DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] like Figure 1 As shown, the utility model provides a valve turbine head with dustproof protection, comprising a turbine head 1, a device body 2 connected to the turbine head 1, an end cover 3 is locked and fixed to the upper end of the turbine head 1, and the end cover 3 is used to seal the inside of the turbine head 1 and also provide protection for the components in the turbine head 1;

[0025] like Figures 2 to 5 As shown, the present embodiment also includes a protection mechanism 4 disposed in the turbine head 1 for providing dust protection for the turbine head 1, the protection mechanism 4 includes a sealing outer ring 44 movably inserted along the inner side wall of the turbine head 1, a fitting groove 42 opened at the top of the outer side of the turbine head 1, and an inclined boss 41 which is arranged along the circumference of the bottom end surface edge of the end cover 3 and corresponds to the fitting groove 42;

[0026] A sealing gasket 43 is fixedly installed in the fitting groove 42 and is in close contact with the inner circle of the inclined boss 41. The sealing gasket 43 is in close contact with the inclined boss 41 to improve the sealing performance in the turbine head 1 and prevent external dust from floating into the turbine head 1.

[0027] The sealing outer ring 44 is coaxially built with the sealing inner ring 45, and a gap is set between the inner ring of the sealing outer ring 44 and the side surface of the sealing inner ring 45 to form a collection groove 46 for collecting dust and impurities. A support sheet 47 is set at the bottom of the collection groove 46, and the inner and outer ends of the support sheet 47 are respectively locked and fixed to the outer surface of the sealing inner ring 45 and the inner ring of the sealing outer ring 44;

[0028] In this embodiment, the inner circle of the inclined boss 41 is tapered from bottom to top, and a corresponding inclined surface is provided on the sealing gasket 43, so that the end cover 3 can drive the inclined boss 41 to move downward to squeeze the sealing gasket 43 during installation, so that the inclined boss 41 can contact the sealing gasket 43 more closely, thereby improving the dustproof effect in the turbine head 1;

[0029] The sealing outer ring 44 is flush with the bottom end surface of the sealing inner ring 45, and the height of the sealing outer ring 44 is less than that of the sealing inner ring 45, so that dust and impurities outside the sealing outer ring 44 can enter the collecting groove 46, reduce the scattering of dust and impurities, and facilitate the subsequent cleaning of dust and impurities.

[0030] In this embodiment, a silicone gasket 411 is fixedly mounted on the top end surface of the sealing inner ring 45, and the silicone gasket 411 is in close contact with the bottom end surface of the end cover 3. The silicone gasket 411 improves the dustproof protection effect of the sealing inner ring 45 on the internal parts of the turbine head 1.

[0031] A positioning groove 48 movably connected to the sealing outer ring 44, the sealing inner ring 45 and the supporting sheet 47 is provided at the inner bottom edge of the turbine head 1. The positioning groove 48 provides positioning for the sealing outer ring 44, the sealing inner ring 45 and the supporting sheet 47, thereby improving the stability of the placement of the sealing outer ring 44, the sealing inner ring 45 and the supporting sheet 47;

[0032] In this embodiment, an annular plate 49 is slidably installed in the positioning groove 48, and the annular plate 49 and the bottom end surface of the support plate 47 are mutually attached, and the annular plate 49 is connected to the inner bottom of the positioning groove 48 through a spring 410, and the spring 410 applies elastic force to the sealing inner ring 45, so that the sealing inner ring 45 drives the silicone gasket 411 to be stably attached to the bottom end surface of the end cover 3;

[0033] The support sheet 47 is an arc-shaped structure, and the support sheet 47 is parallel to the sealing outer ring 44 and the sealing inner ring 45, which improves the stability of the support sheet 47 installed between the sealing outer ring 44 and the sealing inner ring 45;

[0034] In this embodiment, a plurality of grooves are provided at the bottom of the sealing outer ring 44 and the sealing inner ring 45, so that corresponding parts in the turbine head 1 can pass through the grooves to connect to the equipment body 2;

[0035] In this embodiment, the sealing pad 43 is made of silicone, which has a strong anti-aging effect and a long service life;

[0036] When in use, when installing the end cover 3, the inclined boss 41 is driven to be installed on the turbine head 1, and the inclined boss 41 is engaged with the inclined portion of the sealing gasket 43. When the end cover 3 moves downward and is installed on the turbine head 1, the sealing inner ring 45 in the turbine head 1 is squeezed to move downward. The sealing inner ring 45 moves downward to apply thrust to the annular plate 49, and the spring 410 is compressed by the pressure of the annular plate 49. When the end cover 3 is fully installed, the silicone gasket 411 is tightly attached to the bottom end surface of the end cover 3 by the elastic force of the spring 410. When the worm head 1 is in use, the sealing gasket 43, the sealing inner ring 45 and the silicone gasket The sheet 411 is cooperated to provide multiple dust-proof protection for the interior of the turbine head 1. After aging, the silicone gasket 411 can still be moved downward by the elastic force of the spring 410 to fit tightly against the bottom end surface of the end cover 3, and its sealing effect is better. The inclined surface setting of the sealing gasket 43 can not only improve the stability of the contact inclined surface convex body 41, but also effectively reduce the loosening and deviation of the sealing gasket 43, so that the dust-proof protection effect of the turbine head 1 is better. When dust enters the turbine head 1, the setting of the collecting groove 46 can also collect part of the dust. When the dust inside the turbine head 1 is reduced, the stability of the operation of the internal parts of the turbine head 1 can be effectively improved.
