[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] A pressure regulating valve for a gas water heater comprises a valve body 1;

[0023] like Figures 1 to 4 As shown, a multi-way valve core 2 and a one-way valve core 3 are rotatably connected inside the valve body 1. A plurality of flow holes 4 of different apertures are provided on the surface of the multi-way valve core 2. The flow holes 4 are aligned with each other in pairs. The plurality of flow holes 4 are interconnected inside the multi-way valve core 2. The tops of the multi-way valve core 2 and the one-way valve core 3 are both connected with valve stems 5. The top of the valve stem 5 on the top of the multi-way valve core 2 is fixedly connected with a handwheel 6. A convex seat 7 is provided on the top of the valve body 1. A movable block 8 is slidably connected inside the convex seat 7. A groove 9 is provided on the top of the movable block 8. The handwheel 6 cooperates with the groove 9. Springs 10 are symmetrically provided inside the convex seat 7. The bottom of the movable block 8 is elastically connected to the inner wall of the bottom of the convex seat 7 through the spring 10.

[0024] The valve is mainly composed of a multi-way valve core 2 and a single-way valve core 3 inside the valve body 1. The two are connected to the operating parts through the valve stem 5 on their top to realize different control functions. The multi-way valve core 2 is controlled by the handwheel 6 on its top. The surface of the multi-way valve core 2 is provided with a plurality of flow holes 4 with different apertures. These flow holes 4 are aligned with each other in pairs and are interconnected inside the multi-way valve core 2 to form a plurality of different flow channels. By rotating the handwheel 6, the user can alternate these channels to select flow holes 4 with different apertures to circulate gas. Since the apertures of the flow holes 4 are different, the flow rates of different channels will also be different. This design enables the user to control the flow rate of the gas by adjusting the channel according to actual needs, thereby realizing the adjustment of the air pressure. Every one hundred and twenty degrees of rotation of the handwheel 6 can switch to a new channel to realize precise adjustment of the flow rate.

[0025] The movable block 8 not only serves as a reference for the handwheel 6 to help the user identify the adjustment range of the channel, but also can clamp the inner rod of the handwheel 6 through its groove 9 to realize the positioning function. When the groove 9 of the movable block 8 clamps the inner rod of the handwheel 6, the handwheel 6 cannot be rotated without external force, thereby ensuring the stability of the current channel. Only when the movable block 8 is pressed to separate its groove 9 from the inner rod of the handwheel 6, can the handwheel 6 be rotated for adjustment.

[0026] like Figures 1 to 4As shown, a handle 11 is fixedly connected to the top of the valve stem 5 at the top of the one-way valve core 3. The one-way valve core 3 is controlled by the handle 11 at its top. The rotation or push-pull action of the handle 11 can drive the one-way valve core 3 to rotate or move inside the valve body 1, thereby controlling the opening or closing state of the valve, so that the user can quickly and easily adjust the on and off of the gas according to needs.

[0027] like Figures 1 to 4 As shown, valve seats 12 are installed on both sides of the multi-way valve core 2 and the single-way valve core 3 inside the valve body 1. The main function of the valve seat 12 is to support and fix the valve core to ensure that the valve core can rotate or move stably inside the valve body 1.

[0028] like Figures 1 to 4 As shown, trunnions 13 are installed at the bottom of the multi-way valve core 2 and the bottom of the single-way valve core 3 inside the valve body 1. With the support of the trunnions 13, the rotation of the valve core is smoother, friction and wear are reduced, and the service life of the valve is extended.

[0029] like Figures 1 to 4 As shown, a strip groove 14 is provided on the top of the multi-way valve core 2 and the top of the one-way valve core 3, and the bottom ends of the valve stems 5 are respectively slidably inserted into the corresponding strip grooves 14. Through the sliding connection between the strip grooves 14 and the bottom ends of the valve stems 5, the valve cores can maintain a close connection with the valve stems 5 when rotating or moving, thereby preventing the valve cores from falling off or loosening.

[0030] like Figures 1 to 4 As shown, circular grooves 15 are symmetrically provided at the bottom of the movable block 8, and the top ends of the springs 10 are respectively embedded in the corresponding circular grooves 15. Through the elastic force of the springs 10, the movable block 8 can slide stably inside the convex seat 7 and maintain contact or separation with the inner rod of the handwheel 6.

[0031] like Figures 1 to 4 As shown, chamfers are provided on both sides of the top of the groove 9. Guided by the chamfers, the movable block 8 can be pressed more easily to separate or align the groove 9 with the inner rod of the handwheel 6, thereby adjusting or positioning the valve.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
