Description

Technical Field

[0001] The invention relates to a valve, in particular to a pull-and-switch angle valve. Background Art

[0002] There are two main valve core structures used in existing angle valves, one is a ceramic valve core structure, and the other is a ball core structure. However, these two valve cores have their own advantages and disadvantages. The structure adopted by the ceramic valve core is that two ceramic plates fit each other, and the water flow area is controlled by the relative rotation angle. Its advantage is small switching force, and its disadvantages are small flow, many parts, complex structure, and cumbersome installation; the structure adopted by the ball core is a ball core and two sealing gaskets. Its advantage is large flow, but in order to ensure the sealing degree, the ball core and the sealing gasket are installed very tightly, resulting in large switching force and effort.

[0003] Most of the existing angle valves are switched by rotation, that is, a handle is designed for the angle valve, and the water channel is opened and closed by rotating the handle. The control method is single and has more control components, which increases the cost. In addition, users cannot figure out whether turning left or right opens or closes the water channel, and the control instructions are vague.

[0004] The water outlet of the existing angle valve is fixed to the body, but the direction in which the angle valve is installed in the water pipe is uncertain, which will cause the direction of the final water outlet to be not the desired angle, and then cause the hose connected thereto to be entangled. Summary of the invention

[0005] The technical problem to be solved by the present invention is aimed at the deficiencies of the above-mentioned prior art. A pull-and-switch angle valve is provided, which has few parts, is easy to install, is switched by pulling, is fast to switch, has clear operation instructions, and has a universally rotatable water outlet.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pull-and-switch angle valve, characterized in that it includes: a first body, a second body, a plug, a sleeve, and a sealing gasket, the first body is cylindrical, a through hole is set in the middle, one end is a water inlet end, and the other end is a water outlet end; the plug is cylindrical, coaxially arranged on the right side of the water outlet end, a connecting rod is set at one end of the plug, the end of the connecting rod is fixedly connected to the first body, and a water gap is left between the plug and the water outlet end; the sealing gasket is fixedly arranged on the plug, close to one side of the sleeve; the second body is provided with a through hole and a side hole, the through hole and the side hole are connected and arranged in a T shape, the through hole is sleeved on the water outlet end and the plug and sealed, and the side hole is located between the water outlet end and the plug; the sleeve is movably sealed and inserted in the through hole and fixedly connected to the second body, and moves between opening the waterway and closing the waterway. When the waterway is opened, the sleeve is away from the sealing gasket; when the waterway is closed, the sleeve and the sealing gasket are pressed against each other and sealed. The water channel can be opened and closed by pushing and pulling the second body, which is easy to operate and has a simple structure. Moreover, since the two states of pulling up and pushing in are easy to distinguish, you can tell at a glance whether it is currently in the open or closed state, which is more recognizable than the existing knob-type switch.

[0007] Preferably, a spring is further included, and the spring is preloaded and arranged between the first body and the second body, and the preload force direction is the direction in which the sleeve presses the sealing pad. By arranging the spring, the sleeve seal can be made more reliable, and the gear sense is increased, and the operation feel is good.

[0008] Preferably, a bracket is arranged on the water inlet end side, a fixing hole is arranged in the middle of the bracket, and the end of the connecting rod is fixedly arranged on the fixing hole.

[0009] Preferably, the spring is preloaded in the through hole, with one end against the bracket and the other end against the sleeve. The sleeve can be better pressed against the sealing pad under the preload force of the spring, so that the sealing effect in the closed state is better.

[0010] Preferably, a positioning device is further included, and the positioning device is arranged between the first body and the second body, or between the second body and the plug, or between the first body and the sleeve, and the positioning device enables the angle valve to maintain an open waterway state or a closed waterway state. The positioning device is provided to make the angle valve more operable.

[0011] Preferably, the positioning device includes a retaining ring and ring grooves A, B and C, the ring groove C is arranged on the inner wall of the through hole, the ring grooves A and B are arranged on the outer wall of the first body, and the retaining ring is movably arranged in the ring groove C, and engages with the ring groove A when the water channel is open, and engages with the ring groove B when the water channel is closed.

[0012] Preferably, it also includes a fixing part, which is a tubular structure, and an extension part is arranged in the direction of the sleeve; the through hole is provided with a first hole segment and a second hole segment of different diameters; the outer ring of the sleeve is provided with an extension ring; the fixing part is fixedly arranged on the second hole segment, and is coaxially sealed with the plug, and the extension part extends to the extension ring to press and fix the sleeve on the step formed between the first hole segment and the second hole segment. Due to assembly and processing requirements, adding the fixing part can simplify the processing of the second body. Of course, the sleeve can also be directly fixed to the second body using glue or an interference fit assembly method. However, in order to facilitate subsequent after-sales maintenance, a detachable fixing part is added, which saves costs and achieves functionality.

[0013] Preferably, the plug and the connecting rod are separately provided, the plug and the connecting rod are connected and fixed by a threaded structure, and a head is provided at the end of the connecting rod inserted into the fixing hole.

[0014] Preferably, the scanning cross-section of the annular groove A and the annular groove B is a trapezoid, and the cross-section of one side of the clamping ring that matches with the annular groove A and B is a trapezoid. Of course, the cross-sectional shape can also be a semi-arc shape, as long as it is conducive to the clamping ring to smoothly jump from the annular groove A to the annular groove B without being too stuck.

[0041] The following is a specific description with reference to embodiments.

[0042] like Figures 1 to 6 As shown, a pull-switch angle valve of the present invention is characterized by comprising: a first body 100, a second body 200, a plug 500, a connecting rod 400, a sleeve 300, and a sealing gasket 600;

[0043] The first body 100 is cylindrical, with a through hole 110 in the middle, one end is a water inlet end 111, and the other end is a water outlet end 112.
