Short straight-through valve

Abstract

The utility model discloses a short straight-through valve, which comprises a valve body, a valve cover, a valve core, a handle and the like, and is mainly characterized in that the valve core consists of a left static plate which is assembled in the valve body in a sealing manner, a right static plate which is assembled in the valve cover in a sealing manner and a movable plate of which the end surface is attached between the left static plate and the right static plate, and the handle is arranged on the outer surface of the valve body. When the handle does radial reciprocating motion along the outer surface of the valve body, the movable plate can be directly driven to do reciprocating rotation relative to the left static plate and the right static plate so as to open and close the valve; obviously, through the quick-opening valve element structure formed by matching the two static pieces with the movable piece, and the handle directly reciprocates in the radial direction of the outer surface of the valve body without the valve rod, the movable piece can be driven to achieve opening and closing of the valve; meanwhile, after the handle is not designed at one axial end of the valve body, the overall length of the valve can be greatly shortened, and due to the design, the overall structure of the valve is more compact, the size is smaller, and an ultra-short appearance is formed, so that the valve is suitable for a narrow installation space, and the limitation on the installation environment is reduced.

Description

Technical Field

[0001] The utility model relates to a through valve in a pipeline valve, in particular to a short through valve. Background Art

[0002] In daily life, many bathroom products need to be connected to the water supply pipe through straight-through valves such as angle valves. The structures of these straight-through valves usually include valve body, valve cover, valve core and handle. The handle as an operating component must be set outside the valve body and can be connected to the valve core in the valve body through the valve stem to form a drive. Due to the installation of the valve stem, the height dimension of the valve is often larger, making the structure of the valve complicated and the volume larger; at the same time, some straight-through valves set the handle at one axial end of the valve body. Although it solves the height problem of the valve, it will cause the length of the entire valve to become longer. Therefore, these large-volume and long-length straight-through valves will bring installation inconveniences to small installation spaces and also cause great restrictions on the installation environment.

[0023] A short straight-through valve, such as Figure 1~Figure 3 As shown, it is a pipeline valve that is convenient for connecting sanitary products to a water supply pipeline. Its structure is composed of a valve body 1, a valve cover 2, a valve core 3 and a handle 4.

[0024] The valve body 1 and the valve cover 2 are both hollow tubular structures, and the valve cover is installed at one end of the valve body by screwing. Figure 1 The valve cover 2 shown is installed in the threaded hole at the right end of the valve body 1 by threaded tightening through the threaded shaft at the left end, and the right end of the valve cover 2 is connected to the water supply pipe through the threaded hole, and a sealing gasket 6 is also provided in the threaded hole to play a role in connection sealing.

[0025] The valve core 3 is arranged in the valve body 1 and the valve cover 2. The valve core 3 is composed of a left static piece 31 sealedly mounted in the valve body 1, a right static piece 32 sealedly mounted in the valve cover 2, and a dynamic piece 33 whose end faces are fitted between the left and right static pieces. Usually, when the valve cover 2 at the right end of the valve body 1 is screwed and installed in place, the valve core 3 is directly pushed, so that the two end faces of the dynamic piece 33 constituting the valve core are respectively fitted with the right end face of the left static piece 31 and the left end face of the right static piece 32.

[0026] The left and right static plates and the moving plate 33 are all made of ceramic plates, and fan-shaped water holes 34 are provided on the three ceramic plates; moreover, the left static plate 31, the moving plate 33 and the right static plate 32 are on the same axis and overlap with the axis of the valve body 1.

[0027] At the same time, the sealing assembly structure of the left static plate 31 in the valve body 1 is that a left slot 12 with an opening toward the valve cover 2 is provided in the valve body 1, the left static plate 31 is positioned and assembled in the left slot 12, and a sealing gasket 6 that fits each other is provided between the left static plate 31 and the bottom of the left slot 12 to form an installation seal.

[0028] The bottom of the left groove 12 is provided with an annular groove 13 for the sealing gasket 6 to be embedded in, so as to prevent the displacement of the sealing gasket during installation and cause valve leakage.

[0029] The sealing assembly structure of the right static plate 32 in the valve cover 2 is that a right slot 21 with an opening toward the valve body 1 is provided in the valve cover 2, the right static plate 32 is positioned and assembled in the right slot 21, and a sealing gasket 6 is also provided between the right static plate 32 and the bottom of the right slot 21 to form an installation seal.

[0030] Positioning ribs 9 and positioning grooves 10 are respectively provided between the outer circumference of the left static plate 31 and the inner circumference of the left slot 12, and between the outer circumference of the right static plate 32 and the inner circumference of the right slot 21 to form a positioning installation and prevent rotation.

[0031] The movable plate 33 is positioned and embedded in a driving ring 5. Specifically, a positioning rib 9 and a positioning groove 10 for positioning and embedding are respectively provided between the outer circumference of the movable plate 33 and the inner circumference of the driving ring 5. The driving ring 5 is a metal ring on which a protruding handle 51 is provided. After the protruding handle passes through the driving hole 11 on the outer surface of the valve body 1, it is installed with the handle 4 arranged on the outer surface of the valve body 1 by means of glue fastening.

[0032] The driving hole 11 is opened in the outer surface of the valve body 1 in an arc shape along the radial direction, and the handle 4 is an arc block, which is provided with an inner arc surface 41 that fits the outer surface of the valve body 1 and can form radial reciprocating movement, and the outer arc surface of the arc block is provided with anti-slip teeth 42.

[0033] Therefore, when the operating handle 4 moves radially back and forth along the driving hole 11 on the outer surface of the valve body 1, it can drive the movable plate 33 to reciprocate around the axis relative to the left and right static plates through the driving ring 5, and make the water holes on the movable plate 33 overlap with the water holes 34 on the left and right static plates to open the valve or stagger them to close the valve.

[0034] In addition, when the protruding handle 51 moves radially back and forth in the driving hole 11 , it will touch the two ends of the driving hole 11 respectively, thereby constituting a reciprocating rotation stroke limit of the movable plate 33 .

[0035] A wear-resistant gasket 7 that fits together is provided between the driving ring 5 and the valve body 1, that is, between the left end face of the driving ring 5 and the valve body 1, and a sealing ring 8 that fits together is provided between the driving ring 5 and the valve cover 2, that is, between the right end face of the driving ring 5 and the end face of the threaded shaft at the left end of the valve cover 2. The wear-resistant gasket 7 can prevent the driving ring 5 from directly contacting the valve body 1 and causing wear between the two. The sealing ring 8 is usually an O-ring, which can provide a certain amount of compression after the valve cover 2 at the right end of the valve body 1 is screwed into place to ensure that the handle 4 does not feel too heavy when operated, and can also prevent leakage when water flows through the valve core 3.

[0036] The utility model can drive the movable plate 33 to open and close the valve by using a quick-opening valve core structure formed by two stationary plates cooperating with the movable plate 33, and the handle 4 omitting the valve stem and directly moving back and forth radially along the outer surface of the valve body 1. At the same time, after the handle 4 is not designed at one axial end of the valve body 1, the overall length of the valve can be greatly shortened. These designs can make the overall structure of the valve more compact and the volume more compact, and form an ultra-short appearance, so that it is suitable for narrow installation space and reduces restrictions on the installation environment.

[0037] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
