Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an angle valve body. Background Art

[0002] Angle valves are common water flow control devices in daily life. Angle valves control the flow of water by opening or closing operations. The valve body of the angle valve has a water inlet and a water outlet. When in use, the water inlet is connected to the water inlet pipe, and the water outlet is connected to the water outlet for connecting to a faucet or a water heater. An installation cavity is formed in the valve body, and a valve core is fixedly arranged in the installation cavity, and the opening and closing of the water outlet is controlled by the valve core. The fixed installation method of the valve core in the installation cavity usually adopts a threaded locking method, that is, an internal thread section is added at the outer end position of the installation cavity, and an external thread section is added at the corresponding position of the valve core on its shell; when fixedly installed, the valve core extends into the installation cavity from the outer end, and then the external thread section and the internal thread section are locked and matched with each other to complete the installation. The locking method of the internal and external threads requires the valve body to be specially extended to form the internal thread section, which increases the cost of manufacturing the valve body.

[0003] In view of this, the applicant conducted in-depth research on the above-mentioned prior art problems, which led to the present case. Utility Model Content

[0004] The utility model aims to provide an angle valve body, which has the characteristics of simplified structure, reduced valve body height and reduced cost.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] The invention discloses an angle valve body, which has a water inlet and a water outlet, and a valve core cavity for installing a valve core is formed in the valve body; the inner cavity wall at the inner end of the valve core cavity is provided with a first thread for locking the valve core.

[0007] The inner cavity wall at the outer end of the valve core cavity is provided with a second thread for connecting the valve core related explosion-proof safety structure.

[0008] A safety ring for holding the valve core is also arranged at the outer end of the valve body cavity, and a third thread corresponding to the second thread is arranged on the outer side wall of the safety ring.

[0009] The safety ring comprises a ring body, the inner end of which is bent inwardly to form a plane portion for resisting the valve core.

[0010] The free edge of the planar portion is bent upward to form an upward folded portion.

[0011] A reinforcing rib is arranged between the upper folding portion and the ring body.

[0012] The inner end of the valve core cavity forms a limiting step.

[0013] Interface threads are arranged on the outer side walls of the valve body corresponding to the water inlet and the water outlet.

[0014] After adopting the above scheme, the beneficial effect of the new angle valve body compared with the prior art is that the threaded section of the valve core cavity for locking the valve core is set on the inner cavity wall at the inner end, and the space corresponding to the inner cavity wall is the space that originally needs to be set for the corresponding valve core structure. The present application cleverly utilizes the space that originally needs to be set, and sets the first thread for locking the valve core in this space. There is no need to specially extend the relevant threaded section on the outer end of the valve core cavity. This not only reduces the material cost, but also reduces the overall height of the valve body. The present application further sets a second thread on the valve body, and the second thread is set on the inner cavity wall at the outer end of the valve core cavity. The second thread has no direct connection with the valve core, and is used for locking the explosion-proof safety structure of the valve core, bringing explosion-proof safety function to the valve core. Compared with the traditional valve body, the angle valve body of the present application can have more functions and better effects at the same size and height. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Valve body 1, water inlet 11, water outlet 12, valve core cavity 13, first thread 131, second thread 132, limiting step 133; safety ring 4, third thread 41, ring body 42, flat part 43, upper folded part 44, reinforcing rib 45. DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] This case involves an angle valve body, such as Figure 1-4 As shown, the valve body 1 has a water inlet 11 and a water outlet 12, and a valve core cavity 13 for installing a valve core is formed in the valve body 1. The valve core cavity 13 has an inner end and an outer end. The inner end is connected to the water inlet 11 and the water outlet 12 respectively, and the outer end corresponds to the water volume control port of the valve body 1.

[0023] The inner wall of the inner end of the valve core cavity 13 is provided with a first thread 131 for locking the valve core. The space corresponding to the inner wall is the space originally required to be provided for the corresponding valve core structure. The present application cleverly utilizes the space originally required to be provided, and provides the first thread 131 for locking the valve core in this space. There is no need to specially extend the relevant thread section on the outer end of the valve core cavity 13, which not only reduces the material cost, but also reduces the overall height of the valve body.

[0024] The present application further provides a second thread 132 for connecting the explosion-proof safety structure of the valve core on the inner wall of the outer end of the valve core cavity 13. The second thread 132 serves as a matching structure for the explosion-proof safety design of the valve core. Specifically, it is used to lock the safety ring against the valve core. The second thread 132 is provided on the inner wall of the outer end of the valve core cavity 13. The second thread 132 is not directly related to the valve core, but is used for locking the explosion-proof safety structure of the valve core, providing the valve core with an explosion-proof safety function. Compared with the traditional valve body, the angle valve body of the present application can have more functions and better effects at the same size and height.

[0025] Preferably, a safety ring 4 for holding the valve core is further arranged at the outer end of the valve core cavity 13, and a third thread 41 corresponding to the second thread 132 is arranged on the outer wall of the safety ring 4. After the valve core is fixedly installed in the valve core cavity 13, the safety ring 4 is threadedly connected at the outer end through the second thread 132 and the third thread 41. The safety ring 4 further provides a core stabilization guarantee for the fixedly installed valve core, prevents the risk of explosion and overall flying out when the valve core breaks, and well avoids the possibility of flooding caused by a large amount of water gushing out.

[0026] Preferably, the safety ring 4 has a ring body 42, the inner end of which is bent inward to form a plane portion 43 for resisting the valve core. The plane portion 43 is an annular surface structure, which can resist the valve core well and play a good safety role.

[0027] Preferably, the free edge of the plane portion 43 is bent upward to form an upper folded portion 44. The upper folded portion 44 plays a role in strengthening the structural strength of the plane portion 43. Further, a plurality of reinforcing ribs 45 are provided between the upper folded portion 44 and the ring body 42 to strengthen the overall structural stability of the safety ring 4 and the structural strength of the plane portion 43.

[0028] Preferably, a limiting step 133 is formed at the inner end of the valve core cavity 13 , and when the valve core is installed in the valve core cavity 13 , the limiting step 133 limits the valve core to a position where it is installed.

[0029] Preferably, interface threads are provided on the outer side walls of the valve body 1 corresponding to the water inlet 11 and the water outlet 12 .

[0030] The above description is only the preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the claims of the present invention.
