Abstract
The utility model discloses a pressure transforming valve which can automatically change valve opening according to the pressure change of the fluid inside the valve. The structure of the pressure transforming valve is that the center of a valve body is provided with a valve cap assembly, the upper side of the valve cap assembly is provided with a valve cap positioning stopper connected to the valve body, the bottom of the valve cap assembly is connected with a piston, and the lower side of the piston is provided with two pressure maintaining and reset springs which are sheathed with each other and are sealed on the lower part of the valve body by a bottom cap. The utility model used by installing on a branch pipeline can reduce the pressure of a main pipeline. The utility model can be used for installing on the branches of various fluid transferring pipelines.
Description
The utility model relates to a kind of valve that changes its aperture with hydrodynamic pressure.
Now the various valves of domestic and imported are all by mechanical adjustment or electromagnetism adjusting, hydraulic regulation, pneumatic adjusting, and all install controlling device in the valve outside, or the automatic control and adjustment system.Therefore not only use, regulate, installation etc. is all inconvenient but also wasted a large amount of energy.Usually the user is most of in use all is transferred to fixing position to valve, main line has just seriously influenced high rise building water supply when pressure surge, so a lot of enterprise design many water works, improve loine pressure by pipeline mounted pump or other pump, so not only increase cost, and wasted the energy.
The purpose of this utility model provides a kind of valve that utilizes the variation in pressure automatic regulating valve door aperture of fluid, is installed in the loss that can reduce main pipe pressure in the pipeline, improves the capacity of water supply.
The purpose of this utility model is achieved through the following technical solutions: a valve gap assembly is installed in valve body, a valve gap limit plug that is connected with valve body is arranged above the valve gap assembly, the bottom of valve gap assembly links a piston that has seal ring.Be enclosed in pressurize, the Returnning spring of two suits of valve body lower portion below the piston by bottom.
The contact segment of valve body and valve gap assembly is equipped with seal ring.Have aperture on the bottom.
The utility model advantage is because of bonnet lower is connected with piston, can utilize the interior fluid of valve body to the active force of piston and the reaction force of Returnning spring, reaches the purpose of automatic regulating valve lid aperture.Use the pressure loss that this valve can reduce main line effectively.
Fig. 1 is a pressure inverting valve sectional view.
When the valve body inner fluid flows to B by A, A direction fluid pressure hypothesis 7kg/cm
2Liquid flows to fluid pressure moment supercharging in the B pipeline by A, 6 pairs of Returnning springs of piston are exerted pressure, spring is compressed, the valve gap assembly is connected with piston, valve gap fell until closing according to the saturation pressure of spring thereupon when spring was compressed, its B pipeline inner pressure equals the saturation pressure of spring, supposes 2kg/cm
2When B pipeline liquid discharges, its pipeline hydrodynamic pressure descends naturally, Returnning spring upwards promotes piston assembly boosts by A to B supplementary pressure and liquid valve gap assembly 1, the size of valve open is closely related with the pressure in the B pipeline, valve gap assembly 1 falls also with valve closing when the B pipeline is closed, and valve gap assembly location dimension and spring height are all adjustable.Not fragile in the liquid if any impurity seal ring 4 yet, when using, this valve changes easily, and easy to maintenance.
Claims (1)
1, a kind of pressure inverting valve, it is characterized in that: be in the valve body 2 of cross structure a valve gap assembly 1 is housed, it above the valve gap assembly 1 a valve gap limit plunger 3 that links to each other with valve body 2, the bottom of valve gap assembly 1 links to each other with piston 6, is enclosed in pressurize spring 7, the Returnning spring 8 of two suits of valve body lower portion below the piston 6 by bottom 10.
