Description

A kind of mechanical throttle

Technical field

This utility model relates to a kind of mechanical throttle, belongs to throttle valve technology field.

Background technology

Choke valve is that it is in use by changing throttling cross section or the chock length valve with control fluid flow There is no flow negative feedback function, it is impossible to compensate and changed caused speed instability by load, be typically only used for Load change is little or occasion less demanding to speed stability, such as: oil, natural gas, fire-fighting, chemical industry, The industries such as water power, for can not be according to the on-the-spot regulating pondage that is actually needed with the existing equipment of choke valve Size, and more with the time waste of water source adapter before use, thus many time, and, choke valve Typically all it is set to one-way throttle valve, its complicated structure, and also it is cumbersome to operate, and is difficult to control water The size that flow section is long-pending, when returning in normal condition when need not throttling, it is impossible to according to actual needs Carrying out corresponding must changing, how designing choke valve easy to use, controllable becomes those skilled in the art The technical problem urgently to be resolved hurrily faced, accordingly, it would be desirable to improve further.

Utility model content

The technical problems to be solved in the utility model overcomes existing defect, it is provided that a kind of mechanical throttle, passes through Toward control water inlet water inlet, spool moves upward under the effect of the pressure, and water inlet is opened, current start from Water inlet flow into, from outlet discharge, when need not throttling time, by spool by down pressing, current directly from Outlet flows out, and can need to be adjusted choke valve according to practical situation, can effectively solve in background technology Problem.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme:

A kind of mechanical throttle, including valve body and aquaporin, described body top is provided with screw thread coupling, described Screw thread coupling, connection valve gap bottom described screw thread coupling, described screw thread coupling nested encryptions threaded stem, Described threaded stem top connects rotation hand wheel, connects push rod, set bottom described push rod bottom described threaded stem Having spring, be provided with spool below described spring, be provided with circular groove bottom described spool, described body base sets There are chassis, top, described chassis to be provided with elastic supporting bar, and described elastic supporting bar is nested with described circular groove Connecting, described aquaporin runs through valve body, and described aquaporin one end is provided with outlet, and the described aquaporin other end sets Water inlet, described valve body side is had to be additionally provided with control water inlet.

Furthermore, described water inlet, outlet are equipped with screw socket with control water inlet side.

Furthermore, described outlet is located at above described water inlet, described water inlet be located at described control into Above the mouth of a river.

Furthermore, described control water inlet is located between described spool and chassis.

Furthermore, described rotation hand wheel is circular configuration, and described rotation hand wheel outer wall is additionally provided with slip-resistant texture.

This utility model beneficial effect: by toward controlling water inlet water inlet, spool is the most upwards transported Dynamic, water inlet is opened, and current start to flow into from water inlet, discharge from outlet, when need not throttling, By spool by down pressing, current directly flow out from outlet, can need to carry out choke valve according to practical situation Regulation, simple in construction, reasonable in design, practical.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein Preferred embodiment be merely to illustrate and explain this utility model, be not used to limit this utility model.

As Figure 1-Figure 2, a kind of mechanical throttle, including valve body 1 and aquaporin 12, described valve body 1 Top is provided with screw thread coupling 2, connects valve gap 3, described screw thread coupling 2 bottom described screw thread coupling 2 Being threaded connection threaded stem 4, described threaded stem 4 top connects rotation hand wheel 5, described threaded stem Connect push rod 6 bottom 4, be provided with spring 7 bottom described push rod 6, below described spring 7, be provided with spool 8, institute State and bottom spool 8, be provided with circular groove 9, bottom described valve body 1, be provided with chassis 10, top, described chassis 10 It is provided with elastic supporting bar 11, and described elastic supporting bar 11 and described circular groove 9 nested encryptions, described water Passage 12 runs through valve body 1, and described aquaporin 12 one end is provided with outlet 13, described aquaporin 12 other end Being provided with water inlet 14, described valve body 1 side is additionally provided with control water inlet 15.

More specifically, described water inlet 14, outlet 13 are equipped with spiral shell with controlling water inlet (15) side Mouth 16, can be used to external water pipe by screw socket 16.

More specifically, described outlet 13 is located at above described water inlet 14, and described water inlet 14 is located at Above described control water inlet 15, the effect of one-way throttle can be reached.

More specifically, described control water inlet 15 is located between described spool 8 and chassis 10, by controlling Water inlet 15 water inlet produces pressure, thus provides power upwards to spool 8.

More specifically, described rotation hand wheel 5 is circular configuration, and described rotation hand wheel 5 outer wall is additionally provided with anti-skidding Texture, can be pressed spool by rotation hand wheel 5.
