Description

Technical Field

[0001] This utility model relates to the field of valve components, specifically a valve component. Background Technology

[0002] A valve assembly is a mechanical device used to control fluid flow, typically composed of components such as a valve body, valve cover, valve core, and valve seat. The function of a valve assembly is to regulate the flow rate and pressure of fluid in a pipeline by controlling the opening and closing of the valve, thereby achieving fluid control and regulation.

[0003] A search revealed that the invention patent with publication number CN101922585A discloses a valve assembly, including a valve body with an axially through hole, a valve ball rotatably disposed in the valve body and having a hole in the center, a valve seat disposed between the valve ball and the valve body and communicating with the valve body, a valve stem vertically and fixedly connected to the upper end of the valve ball, and a connector connected to one end of the valve body. The connector includes an embedded part and an exposed part.

[0004] Existing valve assemblies, being used with fluid media, are prone to corrosion at the valve stem, which can affect the normal opening and closing of the valve. Alternatively, vibration can cause the valve stem to loosen, leading to poor valve sealing. Therefore, improvements are necessary. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve assembly, including a valve body, a valve seat fixedly connected to the top of the valve body, a valve stem mounted on the valve seat via a bearing, a hollow shell mounted on the top of the valve seat via bolts, the hollow shell slidably sleeved on the outside of the valve stem, a fixing ring fixedly connected to the stem of the valve stem, a gear disc slidably sleeved on the outside of the stem of the valve stem, the gear disc abutting against the hollow shell, a locking tube fixedly connected to the top of the hollow shell, the locking tube penetrating the hollow shell, the locking tube engaging with the gear disc, a sponge sleeve and a beveled block slidably connected to the inner side of the hollow shell, the sponge sleeve and the beveled block contacting each other, a push rod slidably connected to the outer ring wall of the hollow shell, the push rod penetrating the hollow shell, a ball fixedly connected to one end of the push rod, the ball abutting against the beveled block, and a button fixedly connected to the other end of the push rod.

[0007] Preferably, a rotating wheel, made of stainless steel, is fixedly connected to the upper section of the valve stem. The rotating wheel facilitates the rotation of the valve stem.

[0008] Preferably, a guide block is fixedly connected to the inner ring wall of the gear disc, and the guide block is slidably connected to the valve stem. The guide block guides the axial sliding of the gear disc along the valve stem.

[0009] Preferably, a spring is slidably sleeved on the outer side of the valve stem. One end of the spring is fixedly connected to a retaining ring, and the other end is fixedly connected to a geared disc. The spring allows the elastic force to be applied to the geared disc.

[0010] Preferably, a pull rod is fixedly connected to the side of the gear plate, and the pull rod is made of plastic. The pull rod facilitates pulling upwards.

[0011] Preferably, a guide rod is fixedly connected to the inner wall of the hollow shell, and the guide rod is slidably connected to the inclined block. A second spring is provided inside the inclined block, one end of which is fixedly connected to the guide rod, and the other end of which is fixedly connected to the inner surface of the inclined block. The guide rod and the second spring provide auxiliary repositioning for the inclined block.

[0012] Preferably, the inner wall of the hollow shell has an oil outlet hole, and the position of the oil outlet hole corresponds to that of the sponge sleeve. The oil outlet hole facilitates the discharge of lubricating oil.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a hollow shell on the valve seat and outside the valve stem. Inside the hollow shell is an inclined block supported by a spring, and then an annular sponge sleeve is provided. The sponge sleeve can store a certain amount of lubricating oil. In this way, by simply pushing the push rod with a button, the push rod applies pressure to the inclined block, thereby squeezing the sponge sleeve and releasing the lubricating oil, thus lubricating the connection between the valve stem and the valve seat and preventing opening and closing difficulties caused by rust.

[0015] 2. This utility model sets a combination of a fixing ring, a toothed disc, and a spring on the outside of the valve stem, and then sets a locking tube on the top of the hollow shell. In the normal state, the toothed disc will engage with the locking tube under the action of the spring, which can lock and fix the valve stem to prevent it from loosening, thereby ensuring the valve's sealing performance.

The rotating wheel 4 facilitates the rotation of the valve stem 3.

[0023] Please see Figure 1-4 A hollow shell 5 is bolted to the top of the valve seat 2. The hollow shell 5 is slidably sleeved on the outside of the valve stem 3. A fixing ring 8 is fixedly connected to the stem of the valve stem 3. A gear disc 6 is slidably sleeved on the outside of the stem of the valve stem 3, and the gear disc 6 abuts against the hollow shell 5. A guide block 7 is fixedly connected to the inner ring wall of the gear disc 6, and the guide block 7 is slidably connected to the valve stem 3. The guide block 7 guides the axial sliding of the gear disc 6 on the valve stem 3. A spring 9 is slidably sleeved on the outside of the stem of the valve stem 3. One end of the spring 9 is fixedly connected to the fixing ring 8, and the other end of the spring 9 is fixedly connected to the gear disc 6. The spring 9 applies elastic force to the gear disc 6. A locking tube 10 is fixedly connected to the top of the hollow shell 5, and the locking tube 10 penetrates the hollow shell 5 and engages with the gear disc 6. A pull rod 19, made of plastic, is fixedly connected to the side of the gear disc 6. The lever 19 is designed to facilitate pulling upwards.

[0024] Please see Figure 4A sponge sleeve 11 and a beveled block 12 are slidably connected to the inner side of the hollow shell 5, and the sponge sleeve 11 and the beveled block 12 are in contact with each other. A push rod 15 is slidably connected to the outer ring wall of the hollow shell 5, and the push rod 15 passes through the hollow shell 5. A ball 16 is fixedly connected to one end of the push rod 15, and the ball 16 abuts against the beveled block 12. A button 17 is fixedly connected to the other end of the push rod 15.

[0025] The specific implementation process of this utility model is as follows: In use, firstly, the toothed disc 6 is pulled upward by the pull rod 19, so that the toothed disc 6 slides on the outside of the valve stem 3 and compresses the spring 9. At the same time, the toothed disc 6 separates from the locking tube 10 on the hollow shell 5, thus releasing the restriction on the valve stem 3. Then, the valve stem 3 is rotated by the rotating wheel 4 to complete the opening and closing of the valve. After releasing the pull rod 19, the toothed disc 6 will return to its original position under the action of the spring 9 and re-engage with the locking tube 10, thus locking the valve stem 3 again to prevent it from loosening, thereby ensuring the sealing of the valve. In addition, the push rod 15 is pushed by the button 17, so that the push rod 15 applies pressure to the inclined block 12, thereby squeezing the sponge sleeve 11 and releasing lubricating oil, thereby lubricating the connection between the valve stem 3 and the valve seat 2 and preventing opening and closing difficulties caused by rust.
