Abstract
The invention relates to a filter-type glass rotameter comprising a water inlet pipe and a flow adjustment cavity. The filter-type glass rotameter is characterized in that a stainless steel gauze filter is arranged between the water inlet pipe and the flow adjustment cavity and is arranged in a filter cavity. By slightly improving the water inlet end of the minitype glass rotameter, the invention can change the phenomenon of stainless steel floater jamming because larger impurities exist in water when the rotameter runs.
Description
Technical field
The present invention relates to a kind of spinner-type flowmeter, especially a kind ofly be used for the flowmeter that piping system has the stainless steel float.
Background technology
Glass rotors formula flowmeter is widely used in units such as chemical industry, oil, light industry, medical treatment, chemical fertilizer, food, papermaking, environmental protection and synthon, scientific research, its main measuring sensor be one vertical install, the little stainless steel float that can fluctuate in cone-shaped glass graduated tube that big and material is high borosilicate and the pipe of under the diameter, when fluid is flowed through the cone-shaped glass graduated tube from bottom to top, produce pressure reduction between about float, float rises under this differential pressure action.When the power of this rising equates with the gravity of float, float just is in the state of balance, therefore, exist certain proportionate relationship between the height that the fluid flow of the flowmeter of flowing through and float rise and the circulation area of flowmeter, the position height of float can be used as flow and measures.The occasion of using the glass type spinner-type flowmeter in conveyance conduit is a lot, because the medium that uses is clean or do not have process effectively to filter, the time spent need not or use long in adding, tend to cause on cone-shaped glass scale tube wall and the float fouling or have oarse-grained impurity can not by and be stuck between float and the cone-shaped glass scale tube wall, make flowmeter normally not use.
Summary of the invention
The present invention will solve existing glass rotors formula flowmeter in operational process, because the impurity in the fluid media (medium) is stuck between float and the cone-shaped glass scale tube wall, make the technical matters that flowmeter can not normally use, and provide a kind of filter-type glass rotameter, this flowmeter can not change under the situation of measuring the fluid flow characteristic, and bottom base is prevented the stuck effect in the cone-shaped glass graduated tube of float to change just can reach a little.
Technical scheme of the present invention is: a kind of filter-type glass rotameter device, comprise water inlet pipe, the flow regulation chamber is characterized in: be provided with the stainless steel wire web filter between water inlet pipe and the flow regulation chamber, and the stainless steel wire web filter is installed in the filtrator cavity.
The filtrator cavity is arranged in the bottom base, and is connected with the water inlet cavity, water inlet cavity upper end fixed seal connection cone-shaped glass graduated tube, and cone-shaped glass graduated tube upper end links to each other with rising pipe by exhalant canal.The purpose stainless steel cloth is stacked forms by multi-disc 100 for the stainless steel wire web filter.Water inlet pipe is connected with bottom base by screw thread, and its junction is provided with the water inlet gasket circle.The cone-shaped glass graduated tube is fixedlyed connected with bottom base with top base respectively with following clamping cap by last clamping cap.The water outlet packing washer is equipped with in rising pipe and exhalant canal junction.Cone-shaped glass graduated tube and exhalant canal and water inlet cavity junction are equipped with water outlet glass capsulation packing ring and water inlet glass capsulation packing ring respectively.
The present invention compared with prior art has following beneficial effect:
1. do not change the measurement effect of existing flowmeter;
2. when fluid media (medium) was flowed through flowmeter, float can be not stuck in the cone-shaped glass graduated tube;
3. easy to use a, need increase the manufacturing cost of stainless steel wire web filter;
4. it is convenient to change the stainless steel wire web filter.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with description of drawings structure of the present invention and principle of work are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As shown in Figure 1, filter-type glass rotameter of the present invention mainly comprises rising pipe 1, top base 3, exhalant canal 4, cone-shaped glass graduated tube 7, longitudinal sealing bolt 12, handle 13, radial seal bolt 14, flow control rod 15, bottom base 17, flow regulation chamber 18, water inlet pipe 19, stainless steel wire web filter 21, filtrator cavity 22, stainless steel float 23, support plate 24 etc.
Between water inlet pipe 19 and the flow regulation chamber 18 stainless steel wire web filter 21 is housed, stainless steel wire web filter 21 is installed in the filtrator cavity 22.
The cone-shaped glass graduated tube is connected with bottom base 17 with top base 3 with following clamping cap 9 by last clamping cap 6 respectively at two ends about in the of 7; Exhalant canal 3 in the top base 3 is connected with rising pipe 1; The lower end of water inlet cavity 16 is flow regulation chamber 18 in the bottom base 17, the two ends in flow regulation chamber 18 are connected with filtrator cavity 22 with longitudinal sealing bolt 12 respectively, the axle center drilling of longitudinal sealing bolt 12, the flow control rod 15 that has handle 13 passes from the hole, and the outside of longitudinal sealing bolt 12 is a radial seal bolt 14; Stainless steel wire web filter 21 is housed in the filtrator cavity 22, and the opposite side of filtrator cavity 22 is connected with water inlet pipe 19.After stainless steel wire web filter 21 stops up,, can change from taking-up stainless steel wire web filter 21 in the filtrator cavity 22 as long as pull down water inlet pipe 19.
The course of work of the present invention is: after ducted water enters filter-type glass rotameter by water inlet pipe 19, successively flow through filtrator cavity 22 and stainless steel wire web filter 21 in the bottom base 17 seal and in the water inlet pipe 19 and the junction of filtrator cavity 22 water inlet gasket circle 20 is housed; Water filters laggard inbound traffics through stainless steel wire web filter 21 and regulates chamber 18, in flow regulation chamber 18, carrying out flow regulation by the longitudinal sealing bolt 12 that is connected with bottom base 17 and the radial seal bolt 14 fixing flow control rods that have handle 13 15 makes fluid enter into water cavity 16 and cone-shaped glass graduated tube 7, stainless steel float 23 in the cone-shaped glass graduated tube 7 rises to certain height under the effect that fluid media (medium) flows, treat (being that stainless steel float 23 is constant constant at certain altitude) behind the stability of flow, according to the scale on the cone-shaped glass graduated tube 7, can read the flow of the fluid media (medium) under this operating mode; The flow through exhalant canals 4 in the top base 3 and the rising pipe 1 that is connected with the interior exhalant canal 4 of top base 3 of fluid media (medium)s in the cone-shaped glass graduated tube 7 enters operational system, and this operational system can also can be closed for open-type.Top base 3 and bottom base 17 are connected and fixed by securing member and support plate 24 by support plate fixed orifice 27, and cone-shaped glass graduated tube 7 outer organic glass shield 8 are connected and fixed by the organic glass shield fixing threaded hole 26 on securing member and the support plate 24.
