Problems solved by technology

[0004] In order to solve the phenomenon of dripping water for some residents, non-metering of water meters, and difficulty in collecting water fees in the case of severe shortage of water resources, it has led to a great waste of water resources, exacerbated the contradiction between supply and demand of water resources, and improved the water supply of water plants or properties. Economic benefits and control, this application specially develops an anti-drip check ball valve with lock, which can cut off the water flow even in the case of a small flow of water, so as to achieve the anti-drip function

Embodiment 1

[0028] This embodiment is a anti-drip check ball valve with lock, combined with figure 2 with image 3 , including ball valve 1 with ball, disc seat 3, disc frame 5, spring 6 and check valve body 7, check valve body 7 is connected with ball valve 1 with ball, disc seat 3, disc frame 5 and spring 6 Installed in the check valve body 7, one end of the disc seat 3 is connected to the ball valve 1 with a ball, and the other end is set as a conical surface 31; a gasket 4 is installed between the disc frame 5 and the conical surface 31; Set has spring 6. Wherein, the gasket 4 includes an inner end 41 and an outer end 42, the inner end 41 is a fixed end, installed on the disc frame 5, and the outer end 42 is a movable end, which is clamped on the inner side of the tapered surface 31 of the disc seat 3; The return valve body 7 is fixed by a connecting nut 8, and a key 9 is arranged above the ball valve 1 for controlling the opening and closing of the ball valve 1.

Embodiment 2

[0030] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference lies in that an O-ring 2 is set between the disc seat 3 and the ball valve 1 with the ball to play a sealing role.

Embodiment 3

[0032] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that the valve disc frame 5 is an inverted T-shaped structure, including a vertical end 51 and a horizontal end 52, and the end facing the valve disc seat 3 is a vertical end 51, The vertical end 51 is provided with a fixing groove through which the inner end 41 of the sealing gasket 4 is fixed on the disc frame 5 , and the spring 6 is set on the horizontal end 52 .

Abstract

The invention relates to a leakproof ball check valve provided with a lock and belongs to the technical field of valves provided with spherical surface plugs. The leakproof ball check valve comprises a ball valve body provided with a ball, a valve clack holder, a valve clack support, a spring and a check valve body. The check valve body is connected with the ball valve body provided with the ball; the valve clack holder, the valve clack support and the spring are installed in the check valve body; one end of the valve clack holder is connected with the ball valve body provided with the ball, and the other end of the valve clack holder is provided with a conical surface; a sealing pad is installed between the valve clack holder and the conical surface; and the valve clack support is sleeved with the spring. The leakproof ball check valve provided with the lock is an upstream valve applied to meters of water supply and drainage systems including pipe networks in residential living quarters, and mainly used for water utilizing places for preventing and handling the problems that residents use dripping water, water meters fail to measure, water fee is hard to collect, and water meters idle and rotate.

Description

technical field [0001] The invention relates to an anti-drip check ball valve with a lock, which belongs to the technical field of valves with spherical surface plugs. Background technique [0002] The check ball valve is a check structure completed by the joint action of the check valve core body and the ball valve. The valve can only flow in one direction. Existing product structure, combined with figure 1 , is mainly composed of ball valve 1a, gasket 2a, check valve disc 3a, valve body 4a and connecting nut 5a, wherein the check valve disc 3a has only a single check function, when the user uses a small amount of water Under the circumstances, the water meter does not rotate and does not measure, which leads to an invisible economic loss for the property and the waterworks. While water resources are seriously in short supply, it is quite common for some residents to drip water, not measure water meters, and it is difficult to collect water fees, which leads to a great wa...
