Problems solved by technology

In order to improve the sealing performance, the existing technology also adopts a silicone gasket on the sealing end of the valve core to make the sealing effect of the sealing end of the valve core better and prevent the fluid from flowing back. However, since the spring and other parts of the valve core are rigidly connected , susceptible to vibration and affect normal work, poor sealing and stability

Abstract

The invention discloses a one-way valve which comprises a valve body and a valve core mounted inside the valve body, wherein the valve core comprises a water inlet seat and a waterproof cushion used for controlling the switching-on and switching-off of water flow of the water inlet seat; a through hole penetrating through the upper and lower ends of the water inlet seat is formed in the middle part of the water inlet seat; a plurality of water inlets penetrating through the upper and lower ends of the water inlet seat are formed in the circumferential direction of the water inlet seat; the waterproof cushion comprises a waterproof gasket and a waterproof plug; the middle part of the waterproof gasket extends upwards to form the waterproof plug; the waterproof plug penetrates through the through hole to be fixedly connected with the water inlet seat; bosses are arranged on the inner wall of the valve body; and the upper end face of the waterproof gasket is propped against the lower end faces of the bosses. According to the one-way valve, the assembly is easy and convenient, the water current is prevented from flowing back, and the control effect of water flow is good.

Description

technical field [0001] The invention relates to a fluid control valve, in particular to a one-way valve. Background technique [0002] The one-way valve is used to restrict the fluid to flow only along the water inlet, and the outlet medium cannot flow back. The existing one-way valve mainly realizes the displacement of the valve core through the elastic action or reset function of the spring in the valve core, so that the sealing end surface of the valve core is in contact with or separated from the valve body, thereby controlling the on-off of the one-way valve, and the valve core is sealed. The tightness of the end face determines the effect of the check valve. In order to improve the sealing performance, the existing technology also adopts a silicone gasket on the sealing end surface of the valve core, so that the sealing effect of the sealing end surface of the valve core is better and prevents the fluid from flowing back. , is susceptible to vibration and affects nor...
