Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-way control valve technology, specifically a multi-way control valve that is easy to disassemble and maintain. Background Technology
[0002] A multi-way control valve that is easy to disassemble and maintain is a type of multi-way control valve that can be easily disassembled and installed by staff during maintenance.
[0003] Based on the above, the inventors have discovered that while there are many multi-way control valves on the market, most are installed by workers directly using bolts to abut against the equipment body, leaving the bolts exposed on the outside. This leads to dust accumulating on the bolts' outer surface over time, causing wear and severely hindering the disassembly and maintenance of the valve. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a multi-way control valve that is easier to disassemble and maintain, aiming to achieve greater practical value. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model discloses a multi-way control valve that is easy to disassemble and maintain. It includes a multi-way control valve body, with connecting plates fixed on both sides of the multi-way control valve body. The inner walls of the two connecting plates are threaded with two studs, and the outer walls of the two connecting plates are provided with a protective mechanism. The outer walls of the protective mechanism are provided with an installation mechanism.
[0006] The protective mechanism includes:
[0007] Four protective covers are provided on the outer wall of the connecting plate. A perforated plate is fixed on one side of each of the four protective covers. The outer wall of each of the four perforated plates slides against the inner wall of the connecting plate. A sliding plate is fixed to the top of each of the four perforated plates. The outer wall of each of the four sliding plates is fitted against the inner wall of the connecting plate.
[0008] As a preferred embodiment of this utility model, each of the four protective covers has a ring block fixed at its bottom end, and the outer walls of the two connecting plates each have two ring grooves, with the inner walls of the four ring grooves matching the outer walls of the ring blocks.
[0009] As a preferred embodiment of this utility model, the inner walls of both slide plates are equipped with insert plates, and all four insert plates are disposed at the top of the connecting plate.
[0010] As a preferred technical solution of this utility model, the outer wall of the four insert plates is provided with two limiting plates, and both limiting plates are disposed at the top of the connecting plate.
[0011] As a preferred embodiment of this utility model, two protrusions are fixed at the bottom of each of the two limiting plates, and two grooves are opened at the top of each of the two connecting plates. The inner walls of the four grooves are matched with the outer walls of the protrusions.
[0012] As a preferred embodiment of this utility model, the installation mechanism includes:
[0013] Four connecting rods are provided, the outer walls of which slide against the inner wall of the orifice plate. Springs are fitted on the outer walls of the four connecting rods, the top ends of the four springs are fixed to the top end of the inner wall of the connecting plate, and the bottom ends of the four springs are fixed to the top end of the orifice plate.
[0014] As a preferred embodiment of this utility model, the vertical cross-sectional area of the inner wall of each of the four grooves is matched with the vertical cross-sectional area of the outer wall of the protrusion.
[0015] The beneficial effects of this utility model are:
[0016] 1. This solution involves threading the outer wall of the stud onto the inner wall of the connecting plate until the outer wall of the multi-way control valve body is fixedly installed between the valve and the equipment. A sliding plate is used to slide on the inner wall of the connecting plate, causing the orifice plate to slide on the inner wall of the connecting plate. Simultaneously, the orifice plate slides on the outer wall of the connecting rod, thus compressing the spring fitted on the outer wall of the connecting rod. After the connecting plate and the external equipment are in contact, the sliding plate is released, causing the bottom end of the protective cover to abut against the outer wall of the connecting plate. Simultaneously, the outer wall of the protrusion fixed at the bottom of the protective cover engages with the inner wall of the groove. The spring's return force ensures stable protection of the stud's outer wall by the protective cover, preventing dust from the external air from entering the stud's outer surface and causing corrosion. This facilitates easier disassembly and maintenance of the multi-way control valve by the operator.
[0017] 2. In this solution, the outer wall of the insert plate slides against the inner wall of the slide plate, so that the insert plate is positioned at the top of the connecting plate. The inner wall of the limiting plate slides against the outer wall of the insert plate, so that the bottom end of the limiting plate abuts against the top end of the connecting plate. The protrusion fixed at the bottom end of the limiting plate engages with the inner wall of the groove, thereby ensuring that the protective cover is securely installed on the outer wall of the connecting plate.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figures 1-5 As shown, this utility model provides a multi-way control valve that is easy to disassemble and maintain. It includes a multi-way control valve body 1, with connecting plates 2 fixed on both sides of the multi-way control valve body 1. The inner walls of the two connecting plates 2 are threaded with two studs 3, and the outer walls of the two connecting plates 2 are provided with protective mechanisms 4. The outer walls of the protective mechanisms 4 are provided with installation mechanisms 5.
[0027] Protective mechanism 4 includes:
[0028] Four protective covers 41 are provided on the outer wall of the connecting plate 2. A perforated plate 42 is fixed on one side of each of the four protective covers 41. The outer wall of each of the four perforated plates 42 slides against the inner wall of the connecting plate 2. A sliding plate 43 is fixed at the top of each of the four perforated plates 42. The outer wall of each of the four sliding plates 43 fits against the inner wall of the connecting plate 2. A ring block 44 is fixed at the bottom of each of the four protective covers 41. Two annular grooves 45 are provided on the outer wall of each of the two connecting plates 2. The inner wall of each of the four annular grooves 45 matches the outer wall of the ring block 44. Insert plates 46 slide on the inner wall of each of the two sliding plates 43. The four insert plates 46 are provided at the top of the connecting plate 2. Two limiting plates 47 are provided on the outer wall of each of the four insert plates 46. The two limiting plates 47 are provided at the top of the connecting plate 2.
[0029] As attached Figure 4As shown, two protrusions 6 are fixed at the bottom of each of the two limiting plates 47, and two grooves 7 are opened at the top of each of the two connecting plates 2. The inner walls of the four grooves 7 are matched with the outer walls of the protrusions 6, and the vertical cross-sectional area of the inner walls of the four grooves 7 is matched with the vertical cross-sectional area of the outer walls of the protrusions 6, so as to facilitate the fastening and installation of the bottom of the limiting plate 47 and the top of the connecting plate 2.
[0030] As attached Figure 5 As shown, the mounting mechanism 5 includes:
[0031] Four connecting rods 51 are provided, and the outer walls of the four connecting rods 51 slide against the inner wall of the perforated plate 42. Springs 52 are fitted on the outer walls of the four connecting rods 51. The top ends of the four springs 52 are fixed to the top ends of the inner wall of the connecting plate 2, and the bottom ends of the four springs 52 are fixed to the top ends of the perforated plate 42, so that the bottom end of the protective cover 41 can be securely installed against the outer wall of the connecting plate 2.
[0032] Working principle: In use, thread the outer wall of the stud 3 onto the inner wall of the connecting plate 2 until the outer wall of the multi-way control valve body 1 is fixedly installed between the valve and the equipment. Use the sliding plate 43 to slide on the inner wall of the connecting plate 2, causing the orifice plate 42 to slide on the inner wall of the connecting plate 2. Simultaneously, the orifice plate 42 slides on the outer wall of the connecting rod 51, thereby compressing and moving the spring 52 sleeved on the outer wall of the connecting rod 51. After the connecting plate 2 is abutted against the external equipment, release the control of the sliding plate 43, causing the bottom end of the protective cover 41 to abut against the outer wall of the connecting plate 2. At the same time, the outer wall of the protrusion 6 fixed at the bottom end of the protective cover 41 engages with the inner wall of the groove 7. The reset driving force of spring 52 enables the protective cover 41 to stably protect the outer wall of stud 3, preventing dust in the external air from entering the outer surface of stud 3 and causing corrosion. This facilitates the subsequent disassembly and maintenance of the multi-way control valve by the staff. The outer wall of the insert plate 46 slides against the inner wall of the slide plate 43, so that the insert plate 46 is set at the top of the connecting plate 2. The inner wall of the limiting plate 47 slides against the outer wall of the insert plate 46, so that the bottom end of the limiting plate 47 abuts against the top end of the connecting plate 2. The protrusion 6 fixed at the bottom end of the limiting plate 47 engages with the inner wall of the groove 7, so that the protective cover 41 is stably installed on the outer wall of the connecting plate 2.
