Abstract
The utility model relates to an adjustable pressure difference bypass valve, comprising an inclined base body (11) which is respectively communicated with the water inlet and the water outlet of the bypass valve, a bypass adjusting sleeve (7) is arranged in the inclined base body (11), a bypass spring (6) is sheathed on the outer wall of the bypass adjusting sleeve (7), a bypass rod (4) is arranged above the bypass spring (6), and the bypass rod (4) is axially and adjustably connected with the inclined base body (11); compared with the existing pressure difference bypass valve, the adjustable pressure difference bypass valve has adjustable pressure difference, and the adjustable pressure difference bypass valve is arranged at the end of a water dividing and collecting device and is suitable for water paths with different pressures.
Description
Technical field:
The utility model relates to a kind of can regulate differential-pressure bypass valve.
Background technique:
Divide, water-collecting machine is in the water system, is used to connect each road heating pipe for the joining of, backwater, captation.Be divided into water knockout drum, water-collecting machine by advancing backwater.So be called water collecting and diversifying device or condensate correcting-distribuing device.Be widely used in the systems such as floor heating, air-conditioning.Common end at condensate correcting-distribuing device is equipped with differential-pressure bypass valve and is used for regulating water route pressure reduction.When the end load reduces, because turning down the water yield that can cause loading, terminal valve opening reduces, promptly reduce by loop house steward's water flow; Will increase for the pressure reduction between the return main simultaneously, when pressure reduction greater than the force value of setting, the aperture of bypass valve is transferred big, by the flow through flow of bypass tube of increase, keeps total discharge constant.That is to say by regulating the aperture of bypass valve, regulate the flow of the bypass tube of flowing through and isolate the variation of the flow of loading, keep total discharge constant.But the pressure reduction that present employed differential-pressure bypass valve is regulated is definite value, and the water route pressure reduction that has can be big, and the water route pressure reduction that has can be smaller, just can not use for such water route differential-pressure bypass valve.
The model utility content:
In order to overcome the deficiency that exists in the background technique, the utility model provides a kind of can regulate differential-pressure bypass valve, and this can regulate differential-pressure bypass valve is compared with existing differential-pressure bypass valve, and the pressure reduction that is conditioned can be regulated, and is applicable to various water routes.
The technical solution of the utility model is: this can regulate differential-pressure bypass valve comprises oblique pedestal, oblique pedestal is connected respectively with the water intake and the water outlet of bypass valve, the bypass adjustment sleeve is arranged in the oblique pedestal, bypass adjustment sleeve outer wall is with the bypass spring, bypass spring top is the bypass bar, and it is characterized in that: described bypass bar is connected to adjustable with oblique block body axis.
The above-mentioned oblique pedestal upper end can regulate bypass seat that is threaded, the top of bypass bar is threaded with can regulate bypass seat, driving hole is arranged on the bypass bar.
The boss of above-mentioned bypass bar is positioned at the bypass adjustment sleeve, and the two ends of bypass spring are stuck between the shoulder of the shoulder of bypass bar and bypass adjustment sleeve.
Be provided with the bypass sealing gasket between above-mentioned bypass adjustment sleeve and the valve body, be provided with sealing " O " type circle between bypass bar and the can regulate bypass seat.
Above-mentioned can regulate bypass seat upper end screw thread is connected with can regulate bypass nut, is provided with asbestos packing between can regulate bypass seat and the can regulate bypass nut.
Vertical direction with oblique pedestal on the sidewall of above-mentioned bypass valve is provided with interface, and the mechanical temperature table is installed on the interface.
The utlity model has following beneficial effect: owing to take such scheme, this novel bypass spring top is provided with the bypass bar, and the bypass bar can be regulated the stroke of bypass spring, comes the stroke of Regulation spring according to the pressure reduction needs in different water routes, satisfies actual demand.With the pressure reduction that existing differential-pressure bypass valve is regulated is that definite value is compared, and has to use flexible, convenient and advantage of wide range of application.
