Description
Technical field
This utility model relates to a kind of choke valve, particularly to a kind of choke valve based on Pitot tube measurement of discharge.
Background technology
Choke valve be daily and industrial in the highest a kind of valve of practical frequency, choke valve is high with its pressure-bearing, usage range
Extensively, simple in construction, throttle efficiency is high.But current choke valve only plays the effect of throttling, function singleness, in industry and
Family coordinates the also effusion meter that choke valve is practical.In traditional pipeline, choke valve and effusion meter are all separate, so can
Installation cost is made to increase.
Utility model content
This utility model aims to solve the problem that the problems referred to above, it is provided that a kind of choke valve based on Pitot tube measurement of discharge, overcomes
Conventional throttle valve and effusion meter are installed separately, function singleness, the drawback that installation cost is high, and its technical scheme used is as follows:
A kind of choke valve based on Pitot tube measurement of discharge, including valve seat, Pitot tube, sealing screw, valve body inlet, spring,
Spool, push rod, handle, guide rod, valve outlet, described valve body inlet and valve outlet be fixedly attached on valve seat, Pitot tube
Being fixedly mounted on valve seat, Pitot tube entrance is arranged on valve body inlet, and Pitot tube outlet is arranged on valve outlet；Described handle
Connecting push rod, and be arranged in valve seat, spool is arranged on push rod bottom, and guide rod is arranged on valve core inside, and spring housing is at guide rod；Institute
The sealing screw stated is arranged on seat bottom portion, and withstands on guide rod.
Described Pitot tube is made of clear material.
Inside described valve body inlet and valve outlet, female thread is set.
The length of described spring is more than guide rod length.
Beneficial effect: a kind of choke valve based on Pitot tube measurement of discharge, overcomes conventional throttle valve and effusion meter separately peace
Dress, function singleness, the drawback that installation cost is high, use Pitot tube and choke valve to combine, both can realize the effect of throttling, again may be used
To reach to measure the purpose of flow simultaneously, simple in construction, practical.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
Symbol description
1. valve seat, 2. Pitot tube, 3. sealing screw, 4. valve body inlet, 5. spring, 6. spool, 7. push rod, 8. handle, 9.

Detailed description of the invention
The utility model is described in further detail with example below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of choke valve based on Pitot tube measurement of discharge, including valve seat 1, Pitot tube 2, sealing screw 3, valve
Body entrance 4, spring 5, spool 6, push rod 7, handle 8, guide rod 9, valve outlet 10, described valve body inlet 4 and valve outlet 10
Being fixedly attached on valve seat 1, Pitot tube 2 is fixedly mounted on valve seat 1, and Pitot tube 2 entrance is arranged on valve body inlet 4, Pitot tube 2
Outlet is arranged on valve outlet 10；Described handle 8 connects push rod 7, and is arranged in valve seat 1, and spool 6 is arranged on push rod 7 times
Portion, it is internal that guide rod 9 is arranged on spool 6, and spring 5 is enclosed within guide rod 9；Described sealing screw 3 is arranged on bottom valve seat 1, and withstands on
On guide rod 9.
Above-mentioned Pitot tube 2 is made of clear material.
Above-mentioned valve body inlet 4 and valve outlet 10 inside arrange female thread.
The length of above-mentioned spring 5 is more than guide rod 9 length.
Work process: when using this valve, when needs throttle, rotating handles 8, by push rod 7, spool 6 is down pressed,
The water inlet of valve body is blocked by spool 6 compression spring 5, it is achieved throttling；When flow measured by needs, by observing in Pitot tube 2
Liquid level, obtain the liquid level difference of fluid on both sides, drawn the flow velocity of fluid by liquid level difference, afterwards transversal by flow velocity and pipeline
The product of area, then be flow, or check, by liquid level difference, the flow standard table that choke valve is corresponding, immediately arrive at flow.
