The wall of the liquid petrochemical product cylinder bottom water level measuring instrument is provided with a transparent upper valve body with graduation, and a valve rod support rack is arranged on the upper shed of the upper valve body; the upper end of the valve rod which extends out of the valve rod support rack is provided with a hanging ring. The valve rod is sheathed with a spring, one end of the spring is grinded on the valve rod support rack, and another end is grinded on the spring seat. The lower end of the valve rod is sheathed with a valve core whose appearance forms a truncated cone shape, the valve core is made of elastic material, and the valve core is matched with the truncated cone shape through hole of the valve seat. The valve seat is arranged on the lower shed of the upper valve body, and the external thread of the lower part of the valve seat is engaged with the internal thread of the central through hole of the connector. The upper part of the connector of the valve body is provided with uniformly distributed radial direction through holes, and the radial direction through holes are communicated with the through holes of the side wall of the valve seat; the lower part of the connector of the valve body is provided with an external thread, and the external thread is engaged with the internal thread of the lower valve body. The liquid petrochemical product cylinder bottom water level measuring instrument has the advantages of easy and rapid use, and accurate and reliable test data. The liquid petrochemical product cylinder bottom water level measuring instrument solves the problem that the high density, high pour point, and viscous petroleum product can not be detected by the automatic measuring instrument detection method of the water-finding paste, MMC, etc.
Description
Technical field the utility model relates to a kind of surveying instrument.
Background technology is at present in the process of petroleum products trade at home and abroad, and the measuring method of storage tank and oil tanker bilge free water is mainly contained two kinds, automatic measuring instrument detection methods such as water-finding paste and MMC.These two kinds of methods are mainly used in middle low-viscosity oil, and for the oil product of the high and special thickness of the big pour point of density, above-mentioned two kinds of methods all are difficult to measure a jar bilge-water height, reason be MMC etc. automatically in the detection instrument instructions regulation only be applicable to the oil metering that viscosity is lower; And chi hammer self temperature of smearing water-finding paste is low, and when running into the high temperature oil product, the wax in the oil can be solidified rapidly on its surface, form fine and close wax overlayer, make water-finding paste be difficult to contact with the free water of bottom, cause the water-finding paste nondiscolouring, test result is inaccurate.
The summary of the invention the purpose of this utility model is to provide low-viscosity oil jar bilge-water and the accurately big pour point height of density measurement and the liquid petroleum chemical products jar bilge-water gauge of the oil product jar bilge-water height of thickness especially in a kind of can not only accurately the measurement.The utility model mainly includes valve rod, spool, valve seat, upper valve body, valve body web member, following valve body and bottom.Wherein upper valve body is the transparent cylindrical shell that opens wide up and down, and it can be that glass material also can be an ethylene glycol terephthalate (PET).Have scale on this upper valve body wall, preferably also have the flour milling that can be coated with water-finding paste.This upper valve body upper shed is provided with the valve rod support, and it can be the annulus peripheral hardware disc that is complementary with valve rod, and these disc are fixed on the upper valve body again; The lid that also can be provided in a side of the upper valve body upper end, the through hole corresponding with the valve rod external diameter established at middle part on it, and the through hole at other position of lid then is a fluid inlet and outlet.Valve rod, preferably copper valve rod, it stretches out the outer upper end of valve rod support and is provided with link (hook) greater than the carriage center through hole.Be with a spring on the valve rod, the one end withstands on the other end on the valve rod support and withstands on the spring base of valve rod (it can be the special spring base that is provided with, and also can be the shaft shoulder of valve rod).The lower end of valve rod is with the spool of being made by resilient material, and it is provided with the catch that is located in two ends up and down.Above-mentioned spool profile is truncated cone shape, and the truncated cone shape through hole of itself and valve seat is complementary.The horizontally extending edge of this valve seat places on the undergauge of upper valve body under shed, and for preventing seepage, between is established sealing gasket.Valve seat bottom peripheral hardware screw thread, it can be meshed with the internal thread of valve body web member central through hole, and the top of this valve body web member is provided with uniform radial direction through hole, best this through hole cross section semicircular in shape, it is connected with through hole on the valve seat sidewall.This valve body web member bottom is provided with external thread, and its internal thread with following valve body is meshed upper valve body and following valve body are linked together.In the following lower end of valve body, preferably be provided with bottom with holes, in case foreign material, mud enter in the valve.When jar bilge portion greasy filth layer is dark, can adopt basin shape bottom, gauge is stood upright on jar above the bilge portion greasy filth layer, can avoid gauge bottom feed liquor through hole to be stopped up by greasy filth.During use, this instrument relies on deadweight to sink down into a jar bilge portion above oil product, because the density of water is greater than the density of oil, water enters from instrument bottom side opening, and the oil product in the instrument is gone out from displacement suitable for reading.Again because of jar bilge portion pressure is bigger, the water level in the instrument is very fast just consistent with jar bilge portion water level.Upwards lift the moment of this instrument, spool contacts with valve seat, so the liquid in the valve body is intactly put forward, the number of division of reading water-oil interface is jar height of water level of bilge portion.
The utility model has following advantage compared to existing technology:
1. open and close flexible, watertight, test data accurately and reliably.
2. quick, cleanliness of operation easy to use, free from environmental pollution, safety have solved the difficult problem that automatic measuring instrument detection methods such as water-finding paste and MMC all can't detect the oil product of the high and special thickness of the big pour point of density.
3. processing and manufacturing simple in structure, easy, cost are low, easy to carry.
