Abstract
A metering type by-pass valve belongs to the technical field of by-pass valve. The by-pass valve comprises a valve body, and a liquid flow inlet is formed at the top of the valve body and a liquid flow outlet is formed at the bottom thereof; a lug boss is formed on a base of the valve body, a spring is sleeved on the lug boss, a sealing gasket with the size matched with that of the liquid flow inlet is arranged at the top of a spring, and the sealing gasket is pressed on the liquid flow inlet under the elastic action of the spring; and a flowmeter is arranged at the liquid flow outlet. The metering type by-pass valve has a simple structure, is not easy to damage, and can measure the fluid flow rate of the by-pass valve.
Description
Affiliated technical field
The utility model relates to a kind of bypass valve.
Background technique
At present, the bypass valve on the market mainly contains by valve body, by-pass collar to be formed, and its deficiency is existing by-pass collar structure more complicated, in use damages easily, safeguards inconvenience, and can not measure the fluid flow by bypass valve.
Summary of the invention
In order to overcome existing bypass valve arrangement complexity, damage easily, can not measure shortcoming by the fluid flow of bypass valve, the utility model provides a kind of metering type bypass valve, this metering type bypass valve arrangement is simple, is not easy to damage, and can measure the fluid flow by bypass valve.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of metering type bypass valve, comprise valve body, the top of valve body has the flow of liquid inlet, and the bottom of valve body has liquid flowing outlet, the base of valve body is provided with boss, be with spring on the boss, the top of spring is provided with sealing gasket, and the size of sealing gasket and flow of liquid inlet are complementary, sealing gasket is pushed down the flow of liquid inlet under the elastic force effect of spring, liquid flowing outlet is provided with flowmeter.
The beneficial effects of the utility model are that owing to adopt said structure, this metering type bypass valve arrangement is simple, is not easy to damage, and can measure the fluid flow by bypass valve.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural drawing of embodiment's metering type bypass valve.
Embodiment
As shown in Figure 1, a kind of metering type bypass valve, comprise valve body 1, the top of valve body 1 has flow of liquid inlet 2, and the bottom of valve body 1 has liquid flowing outlet 3, the base of valve body 1 is provided with boss 4, be with spring 5 on the boss 4, the top of spring 5 is provided with sealing gasket 6, and the size of sealing gasket 6 and flow of liquid inlet 2 are complementary, sealing gasket 6 is pushed down flow of liquid inlet 2 under the elastic force effect of spring 5, make flow of liquid inlet 2 be in sealing state.Liquid flowing outlet 3 is provided with flowmeter 7, and flowmeter 7 can be measured the fluid flow by bypass valve, is convenient to control.
During use, when flow of liquid enters the mouth the fluid pressure in 2 outsides when raising, when fluid pressure during greater than the elastic force of spring 5, sealing gasket 6 is opened, and liquid flows into from flow of liquid inlet 2, flows out from liquid flowing outlet 3, and bypass valve is in opening state.
When flow of liquid enters the mouth the fluid pressure in 2 outsides when reducing, when fluid pressure during less than the elastic force of spring 5, sealing gasket 6 sealing liquid inflow entrances 2, bypass valve is in closed state.This elastic force bypass valve arrangement is simple, easy to maintenance.Therefore, this metering type bypass valve arrangement is simple, is not easy to damage, and can measure the fluid flow by bypass valve.
Claims (1)
