Abstract
The utility model relates to a pressure valve and consists of a lower valve body, a pagoda spring, an upper valve body, a valve, a sealing gasket, a sealing ring and a valve core. The utility model is characterized in that the lower valve body is fastened and connected with the upper valve body, a sealing gasket is arranged outside the joint of the upper valve body and the lower valve body, and a sealing ring is arranged at the upper part of the sealing gasket. A spring cover is arranged in the central notch on the top of the upper valve body, and an upper cover spring is arranged inside the spring cover. The top of the valve core penetrates deeply into the interior of the spring cover and is connected with one end of the upper cover spring. The upper end and the lower end of the pagoda spring are respectively connected with the internal middle position of the valve core and the lower valve body. The pressure valve has the advantages of non-outletoilline design, simple structure, better sealability, low noises and more stable fluctuation in working performance.
Description
Technical field
The utility model relates to a kind of pressure valve.
Background technique
The pressure valve that general automobile is used its adopt be the oil circuit design, and volume is bigger, in conjunction with the actual use condition of automobile pressure valve and motorcycle, the pressure valve of no oil circuit mode can be applied in the motorcycle electric spraying oil-fired system.But the sealing of the pressure valve of this kind mode is difficulty relatively, because it adopts columniform pitch spring to make pressure surge big; In addition, under the flow system flow variation situation greatly, its service behaviour can produce very big fluctuation.
The model utility content
The purpose of this utility model provides a kind of pressure valve, with the complex structure that overcomes existing product, the deficiency that sealing is difficult, the service behaviour fluctuation is bigger.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of pressure valve, comprise valve body, pagoda spring, upper valve body, valve, sealing gasket, seal ring and spool down, following valve body and upper valve body are fastened and connected together, and upper valve body is provided with one deck sealing gasket with the outside of following valve body junction, and the top of sealing gasket is provided with seal ring; Be provided with spring cup in the intermediate recesses at upper valve body top, the inside of spring cup is provided with lid spring, the top of spool is goed deep into the inside of spring cup and is connected with an end of last lid spring, and the upper and lower end respectively of pagoda spring connects the bosom position of spool and following valve body.
The beneficial effect of pressure valve described in the utility model is: adopt no oil circuit design, and simple in structure; Sealing is better, noise is little, the service behaviour fluctuation is more stable; Valve cooperates with upper valve body and has the effect of fuel oil being carried out switch, and pagoda spring has the effect of regulating system fuel pressure.
Description of drawings
