Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of dynamic differential pressure balancing valve with locking valve and outlet valve.
Background technique
Dynamic differential pressure balancing valve, do not need any external energy, rely on and adjusted the variation of medium self pressure to automatically adjust, automatically eliminate the residual pressure head of pipe network and the changes in flow rate that pressure surge causes, constant user's inlet outlet pressure differential, be specially adapted in household metering or automatic control system, contribute to stable system operation.
Along with the enforcement of the civil building household metering charge of central heating, in order to save heating cost, generally all should organize thermostat valve is installed on radiator at each.Therefore thermostat valve constantly regulates in the running of system, and whole heating system is no longer flow setting type and become variable-flow operation.For in running, guarantee that the pressure reduction of modulating valve or thermostat valve front and back, within the scope of normal operating pressure differential, just need to adopt differential pressure control valve.Dynamic differential pressure balancing valve is also referred to as Differential Pressure Controller, and it is comprised of valve body and control gear two-part.In variable flow system, it,, by the pressure of 2 in induction pipe-line system, can make the pressure reduction of controlled loop keep constant, guarantees the normal work of regulating valve in controlled loop.
Dynamic differential pressure balancing valve possesses automatic elimination and stops up function, as found, this flow system flow is excessive or too small, and foreign material jam when possible reason is piping element installation, on valve plug, can be closed a period of time by PRESSURE PIPE, at this moment if gentlier stop up, can automatically eliminate.Realize PRESSURE PIPE closing function, prior art adopts the method that adds ball valve in PRESSURE PIPE more.This kind of complex structure, increases cost.
In addition, in PRESSURE PIPE water flowing, enter in dynamic differential pressure balancing valve process, if there is no venting gas appliance, hyperbaric chamber air is difficult to discharge, because the compressibility coefficient of gas and liquid is different, can dynamic differential pressure balancing valve be used and be impacted, reaction pressure changes in time, may appear at pressure hysteresis and inaccurate situation, simultaneously, PRESSURE PIPE is easily brought bubble into, needs venting gas appliance.
Existing dynamic differential pressure balancing valve adopts built-in spring to realize balance pressure reduction function, and this kind of structure is unfavorable for spring to carry out dynamic adjustments.
Be more than in prior art, dynamic differential pressure balancing valve shortcomings.There is the design of a kind of simple possible to be supplied thoroughly to solve.
Model utility content
The shortcoming existing in order to overcome existing equilibrium valve, the utility model provides the dynamic differential pressure balancing valve with locking valve and outlet valve.This equilibrium valve, by locking valve and outlet valve are set in equilibrium valve, solves the technical problem of equilibrium valve locking and exhaust.
The scheme that the utility model technical solution problem adopts is:
In equilibrium valve stem lower portion, be provided with spring seat and nut, the outlet valve forming by round nut, upper diaphragm seat and diaphragm in lower diaphragm one side, at lower diaphragm opposite side, be provided with bottom, and by gland nut, gland and O shape circle, PRESSURE PIPE be installed, PRESSURE PIPE is connected with locking valve assembly;
Outlet valve is provided with exhaust port;
In the adapter of locking valve, be provided with interior hexagonal hole, the 2nd O shape circle, the 3rd O shape circle and Rubber end be housed in adapter, and be provided with t-joint, on t-joint, be provided with bypass.
Good effect, the dynamic differential pressure balancing valve locking valve compact structure of the utility model band locking valve and outlet valve, be easy to realize, and, when adapter screws in t-joint completely, bypass is closed, thoroughly solved and will between tee union and dynamic differential pressure balancing valve, increase the problem of ball valve, be convenient to debugging and operation.Outlet valve is directly installed on dynamic differential pressure balancing valve bottom, and there is exhaust port outlet valve side, can effectively gas be discharged.Spring adopts external mode, simple in structure, facilitates Regulation spring pretightening force.The upper and lower diaphragm seat means of fixation of diaphragm, reliable in structure, has very large benefit for improving the diaphragm life-span.Suitablely as dynamic differential pressure balancing valve, use.

Embodiment
According to the figure,
In equilibrium valve valve rod 10 bottoms, be provided with spring seat and nut 9, the outlet valve 4 forming by round nut 1, upper diaphragm seat 2 and diaphragm 3 in lower diaphragm 5 one sides, at lower diaphragm opposite side, be provided with bottom 16, and by gland nut 13, gland 14 and O shape circle 15, PRESSURE PIPE 12 being installed, PRESSURE PIPE is connected with locking valve assembly 11;
Outlet valve is provided with exhaust port 4.1;
In the adapter 11.1 of locking valve, be provided with interior hexagonal hole 11.11, the 2nd O shape circle the 11.2, the 3rd O shape circle 11.3 and Rubber end 11.4 be housed in adapter, and be provided with t-joint 11.5, on t-joint, be provided with bypass 11.51.
Using process of the present utility model:
Locking valve assembly can be crossed the PRESSURE PIPE outlet valve that is connected with dynamic differential pressure balancing valve bottom and be connected with bottom.
In described locking valve assembly, take over interior hexagonal hole, available spanner regulates its position in t-joint, and adapter and t-joint adopt and be threaded.When adapter screws in t-joint completely, bypass is closed, and that is to say and has cut off PRESSURE PIPE circulation.The 2nd O shape circle makes to take over realizes sealing in rotary course.
Described adapter chamfer surface and t-joint right angle side line form sealing, place Rubber end and take over hexagonal hole end for sealing, in adapter when needs pressure measurement, back down Rubber end and realize connection pressure measurement, while not needing pressure measurement, owing to there is certain pressure, Rubber end is withstood on and is close to taper mouth place.
Described PRESSURE PIPE two adopts same sealing means, and one end is connected with dynamic differential pressure balancing valve bottom, and one end is connected with t-joint bypass.Specifically, gland press fit over PRESSURE PIPE proximal port place, and PRESSURE PIPE is stretched out gland end face one segment distance, can place an O shape circle at this extended position, in addition, extension can enter in t-joint by-pass hole, play directing effect, when gland nut is pressed in gland away from an O shape circle one end, an O shape circle is compressed, thereby realize sealing, wherein, gland nut and PRESSURE PIPE are Spielpassung, after installation, PRESSURE PIPE can freely be placed, convenient installation.
Described spring and spring seat coordinate, can be when turn nut, Regulation spring decrement, thereby, change initial tension of spring, further, when control diaphragm has pressure difference in both sides, diaphragm band ovable valve stem displacement distance, controls the aperture gap between spool and valve seat, and then realizes dynamic differential pressure balancing valve pilot line pressure reduction.
Described round nut is pressed on upper diaphragm seat and is screwed on lower diaphragm seat, diaphragm is sandwiched in the middle of upper and lower diaphragm seat, and, upper and lower spring seat is placed diaphragm position respectively arc groove, there is respectively fillet at cylindrical place, effectively prevent that diaphragm from deviating from, and prevent that diaphragm is cut in the process of moving up and down, effectively extended its working life.
