Problems solved by technology

[0002] Road / pipe cleaning machines require high-pressure excited water flow, and usually operate with a high-pressure water pump. During the operation of the high-pressure water pump, the existing structure is due to the design of the flow channel, the installation direction of the check valve, and the vibration during the operation of the vehicle unit. A variety of factors lead to uneven force on the valve plate, the movement state of the valve plate is one side does not move, and the other side moves open and close, and the sealing performance of the valve plate cannot be guaranteed during the closing process, which directly causes the valve or The volumetric efficiency of the pump is reduced, and the wear of the valve plate and valve cover is accelerated, thereby reducing the service life of the check valve

Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, a high-pressure check valve suitable for a high-pressure plunger pump of a washing machine includes a valve seat 1 and a valve cover 2 fixedly connected to the valve seat 1, and the valve seat and the valve cover are in a sealed connection. The valve cover 2 is provided with an elastic pressing part 3, and a valve plate 4 between the elastic pressing part 3 and the valve seat 1. The valve cover 2 is provided with a valve capable of reciprocating vertically. Core 5, the axis line of the valve core 5 coincides with the axis line of the valve cover 2, and the end of the valve core 5 near the valve plate 4 has a ball head 6, and the valve plate 4 is provided with a ball The contact surface of the head 6 that is matched and recessed toward the inside of the valve plate 4 , the valve core 5 passes through the elastic pressing member 3 and the ball head 6 is located below the elastic pressing member 3 so that the ball head 6 is pressed...

Abstract

The invention provides a high-pressure one-way valve suitable for a high-pressure plunger pump of a cleaning machine, and belongs to the technical field of high-pressure one-way valves. The high-pressure one-way valve comprises a valve base and a valve bonnet fixedly connected with the valve base; an elastic compressing part and a valve block between the elastic compressing part and the valve baseare arranged inside the valve bonnet; a valve element moving in the vertical direction in a reciprocating mode is arranged inside the valve bonnet; a ball is arranged at the end, close to the valve block, of the valve element; the valve block is provided with a contact face matched with the ball and concaved inwards the valve block; and the valve element penetrates through the elastic compressingpart and the ball is located below the elastic compressing part, so that the ball is pressed on the valve block. The contact abrasion probability of the valve block and the valve bonnet is greatly reduced, so that the service life of the one-way valve, especially the valve bonnet is prolonged.
