Abstract
The utility model provides a pressure sensing and liquid supplying regulation valve and belongs to the technical field of mechanical equipment. The pressure sensing and liquid supplying regulation valve comprises an elastic metal sheet, an adjustment spring, a valve core, a valve rod and pressure sensing tubes. The valve core is arranged on the valve rod, the upper side and the lower side of the valve rod are respectively connected with the elastic metal sheet and the adjustment spring, and an opening-closing opening is arranged in the liquid supplying regulation valve. The pressure sensing pipes are respectively arranged at an exit and an entrance. The pressure sensing and liquid supplying regulation valve has the advantages of being simple in structure, convenient to operate, suitable for transportation of various media, and convenient to install and use.
Description
Technical field
The utility model relates to a kind of pressure-sensitive feed flow modulating valve, belongs to mechanical equipment technical field.
Background technique
Modulating valve has another name called control valve, in the industrial automation process control field, by accepting the control signal of regulation unit output, removes to change the final control unit of the process parameters such as rate-of flow, pressure, temperature, liquid level by power operation.Regulator apply valve is in media such as air, water, steam, various Korrosionsmedium, mud, oil products.Be divided into pneumatic control valve, electric control valve, hydraulic adjusting valve is from force regulating valve.And at present, accept the modulating valve that the control signal of regulation unit output is regulated, structure is comparatively complicated usually, is not easy to operation.
The model utility content
For solving the problems such as existing regulating valve structure is complicated, operation is difficult, the utility model provides a kind of pressure-sensitive feed flow modulating valve, realizes by following technical proposal.
A kind of pressure-sensitive feed flow modulating valve, comprise resilient blade, Regulation spring, spool, valve rod and pressure nozzle, spool is arranged on the valve rod, and valve rod links to each other with Regulation spring with resilient blade respectively up and down, feed flow modulating valve inside arranges and opens and closes mouth, and pressure nozzle is arranged at respectively outlet and ingress.
, the degree of superheat on the low side when the pressure nozzle temperature of ingress hour, the pressure that the pressure that bear the resilient blade bottom just bears greater than top, resilient blade moves up, and moves on the band ovable valve stem, and spool moves to closing direction, and the transfer body flow is reduced; Otherwise, when the pressure nozzle temperature drift of ingress, when the degree of superheat is large, the pressure that the pressure that bear the resilient blade bottom just bears less than top, resilient blade moves down, the band ovable valve stem moves down, and spool moves to opening direction, and the transfer body flow is increased.
The beneficial effects of the utility model are: this pressure-sensitive feed flow regulating valve structure is simple, easy to operate, and the transmission that is used for all kinds of media all is convenient to install and use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, resilient blade, 2, Regulation spring, 3, spool, 4, valve rod, 5, pressure nozzle.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
Embodiment 1
Such as Fig. 1, pressure-sensitive feed flow modulating valve comprises resilient blade 1, Regulation spring 2, spool 3, valve rod 4 and pressure nozzle 5, spool 3 is arranged on the valve rod 4, valve rod 4 links to each other with Regulation spring 2 with resilient blade 1 respectively up and down, feed flow modulating valve inside arranges and opens and closes mouth, and pressure nozzle 5 is arranged at respectively outlet and ingress.
, the degree of superheat on the low side when pressure nozzle 5 temperature of ingress hour, the pressure that the pressure that bear resilient blade 1 bottom just bears greater than top, resilient blade 1 moves up, and moves on the band ovable valve stem 4, spool 3 moves to closing direction, and the transfer body flow is reduced; Otherwise, when pressure nozzle 5 temperature drifts of ingress, when the degree of superheat is large, the pressure that the pressure that bear resilient blade 1 bottom just bears less than top, resilient blade 1 moves down, band ovable valve stem 4 moves down, and spool 3 moves to opening direction, and the transfer body flow is increased.
