Description
Technical field
The utility model relates to a kind of adjustable-pressure bypass valve.
Background technique
Bypass valve is on a kind of bypass tube that is arranged on inlet valve pipeline section, in order to the valve of hydraulic pressure before and after water-filling balance inlet valve.Bypass valve of the prior art is independent valve body, and according to different clients' needs, the spring ratio of its internal structure, size and spring is all not identical.For client, the parameter that often will think about in use required bypass valve is bought again,, because the parameter of each bypass valve is different, in the time breaking down, must replace with identical bypass valve meanwhile; So greatly increase client's workload and maintenance difficulty in advance, improved the user cost of product.For producer, also need to produce respectively according to different clients the bypass valve of various pressure parameters, the production and administration of enterprise is caused to a lot of troubles.
So bypass valve of the prior art exists and uses the deficiencies such as finished product is high, cost of production is high, maintenance difficulty is large.
Model utility content
Problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides that a kind of user cost is low, cost of production is low, is convenient to the adjustable-pressure bypass valve of maintain and replace.
The technological scheme that the utility model adopts is: the utility model comprises shell, be arranged on water intake and water outlet on described shell, by the connecting pipe of described water intake and the connection of described water outlet, be arranged on the plug of described cover top portion and be positioned at described connecting pipe and for controlling the valve core device of on off operating mode of described water intake and described water outlet, described valve core device comprises the valve body that is fixed on described connecting pipe, be arranged on described valve body and sealing block that in the vertical direction and described valve body are slidably matched, and the adjustable lever of described plug screw-thread fit and be arranged on described adjustable lever and described sealing block between pressure spring, the base plate of described valve body is provided with through hole, described adjustable lever and described sealing block are slidably matched, described sealing block is stated through hole in the effect lower cover residence of described pressure spring, stretch out outside described plug at described adjustable lever top.
On the outer surface of described plug and described valve body and the contact position of described inner surface of outer cover, be equipped with seal ring on the contact position of described adjustable lever outer surface and described plug internal surface.
Described sealing block upper end is provided with traveller, and lower end is provided with lower traveller, and described valve body bottom is provided with coaxial aperture, and described adjustable lever bottom is provided with groove, and described upper traveller inserts in described groove, and described lower traveller inserts in described coaxial aperture.
On described sealing block, be also provided with restraining groove, described adjustable lever lower end is provided with limiting board, and described pressure spring one end is located on described limiting board, and the other end is located in described restraining groove.
The beneficial effects of the utility model are: because the utility model comprises shell, be arranged on water intake and water outlet on described shell, by the connecting pipe of described water intake and the connection of described water outlet, be arranged on the plug of described cover top portion and be positioned at described connecting pipe and for controlling the valve core device of on off operating mode of described water intake and described water outlet, described valve core device comprises the valve body that is fixed on described connecting pipe, be arranged on described valve body and sealing block that in the vertical direction and described valve body are slidably matched, and the adjustable lever of described plug screw-thread fit and be arranged on described adjustable lever and described sealing block between pressure spring, the base plate of described valve body is provided with through hole, described adjustable lever and described sealing block are slidably matched, described sealing block is stated through hole in the effect lower cover residence of described pressure spring, stretch out outside described plug at described adjustable lever top.While using the utility model, only need to regulate by described adjustable lever the compression distance of described spring, the more cracking pressures of compression are larger, otherwise less, and described spring is worked within the scope of different pressures.So the utility model is spool frequently, lower user cost; Meanwhile, only need to produce same bypass valve when manufacturer production, client can regulate the pressure parameter of described bypass valve voluntarily, greatly reduces cost of production.
On the outer surface of described plug and described valve body and the contact position of described inner surface of outer cover, be equipped with seal ring on the contact position of described adjustable lever outer surface and described plug internal surface.So sealing of the present utility model is high.
