Abstract

The utility model relates to an adjusting valve, in particular to a load adjusting valve with manual adjustment function. The load adjusting valve comprises a valve body and an execution mechanism. An air source enters the space above an inner piston of a piston cylinder from the upper end cover of the piston cylinder of the execution mechanism. The lower part of the inner piston of the piston cylinder is correspondingly provided with a matched valve rod and a return spring. An adjusting screw is arranged in the center of the upper end cover of the piston cylinder. The adjusting screw is connected with the upper end cover through threads and a sealing structural member. The upper end of the adjusting screw is provided with an adjusting handle. The end of the adjusting screw penetrating into the piston cylinder acts on the top of the piston. The load adjusting valve has reasonable design and simple structure, does not increase the cost of existing adjusting valve structure basically, realizes the manual control and adjustment function of the adjusting valve, widens the functions of the load adjusting valve, enlarges the range of use, has strong practicability, and is convenient to operate.

Description

A kind of Load Regulation valve
One, technical field: the utility model relates to a kind of modulating valve, particularly relates to a kind of Load Regulation valve with manual tune function.
Two, background technique: modulating valve is widely used in fields such as oil, chemical industry, papermaking, mining, electric power, liquid gas, food, pharmacy, plumbing at present.Because the air bladder sleeve adjusting valve adopts the top guide structure, have compact structure, in light weight, be active in one's movements, advantages such as droop loss is little, Flow characteristics is accurate, easy accessibility, thereby be widely used in the process parameter of accurate control gaseous, liquid and other medium, make pressure, flow, temperature, the liquid level of medium remain on setting value.But in actual production process, some use occasion does not need automatic control, perhaps need manual intervention under specific circumstances, though and present modulating valve can adapt to the maintenance valve position at open and close or a certain valve position state with control signal under normal automatic control state, but can only be in closure under nonserviceabling and open two states (unless spool, valve rod or piston etc. are stuck), this situation is unallowed in some production process.Therefore in actual use, needs and adaptation emergency case in order to overhaul all have been installed in parallel manual control valve at the pipeline section that modulating valve is installed usually, and this needs to increase construction investment undoubtedly, also there is no need sometimes.And pneumatic control valve utilizes pressurized air as power, is subjected to the source of the gas condition restriction or pressure instability occurs, and the Load Regulation valve is just inaccurate to the adjusting of flow and pressure, accurately regulating and controlling valve intake and exhaust/water yield.
Three, model utility content:
The utility model proposes a kind of Load Regulation valve at the prior art deficiency, under with the gas source valve closed condition, and by manual regulating and controlling, accurate regulating and controlling valve intake and exhaust/water yield still.
The technological scheme that the utility model adopted:
A kind of Load Regulation valve, contain valve body and actuator, described actuator adopts pneumatic power, source of the gas enters into piston/cylinder inner carrier top from the upper end cap of the piston/cylinder of actuator, corresponding coupling is provided with valve rod and Returnning spring in the bottom of piston/cylinder inner carrier, upper end cap central position at described piston/cylinder is provided with an adjusting screw, described adjusting screw is connected by screw thread and seal structural part with upper end cap, adjusting screw is positioned at the outer part end of upper end cap and is provided with regulating handle, and the end that adjusting screw penetrates part in the piston/cylinder acts on piston tip.
Described Load Regulation valve is connected or the hinged briquetting that is provided with its one in described adjusting screw lower end, and adjusting screw acts on piston tip by described briquetting.
Described Load Regulation valve is fixed a cushion block at the upper-end surface and the adjusting screw corresponding position of described piston/cylinder inner carrier, and adjusting screw acts on piston tip by described cushion block.
Useful good effect of the present utility model:
The utility model Load Regulation valve, reasonable in design, simple in structure, do not increase existing modulating valve construction cost substantially, realized the manual regulating and controlling function of modulating valve, expanded its function, enlarged using scope, practical, easy to operate.
Four, description of drawings:
Fig. 1: one of the utility model Load Regulation valve arrangement schematic representation
Fig. 2: two of the utility model Load Regulation valve arrangement schematic representation
Five, embodiment:
Embodiment one: referring to Fig. 1, the utility model Load Regulation valve, contain valve body and actuator, valve body and actuator are connected, actuator adopts pneumatic power, source of the gas enters into the top of piston/cylinder inner carrier 3 from the upper end cap 2 of the piston/cylinder 1 of actuator, corresponding coupling is provided with valve rod 9 and Returnning spring 8 in the bottom of piston/cylinder 1 inner carrier, the utility model Load Regulation valve and existing modulating valve structure difference are: be provided with an adjusting screw 6 in the upper end cap central position of described piston/cylinder, described adjusting screw 6 and upper end cap 2 are by coupling be threaded (the corresponding seal structural part that is provided with), adjusting screw 6 is positioned at the outer part end of upper end cap and is provided with regulating handle 7, and the end that adjusting screw 6 penetrates part in the piston/cylinder acts directly on piston 3 tops.Number in the figure 4 is " O " shape seal ring, and 5 for connecting the shaping structure spare of source of the gas.
Embodiment two: referring to Fig. 1, the Load Regulation valve of present embodiment is fixed a briquetting 10 (or cushion block) at the upper-end surface and the adjusting screw corresponding position of described piston/cylinder 1 inner carrier 3, and adjusting screw 6 acts on piston tip by described briquetting 10 (or cushion block).
Embodiment three: referring to Fig. 2, number in the figure is identical with the identical representative meaning of embodiment one, does not repeat.What present embodiment Load Regulation valve and embodiment two were different is: be connected with its one or a hinged briquetting 10 in described adjusting screw 6 lower ends, adjusting screw 6 acts on piston tip by described briquetting.
