Description

Vertical spiral wing type water meter with pressure taking port on meter shell cover plate
Technical Field
The utility model relates to a perpendicular spiral shell wing formula water gauge especially indicates a perpendicular spiral shell wing formula water gauge of pressure port is got in watchcase apron area.
Background
In a large-caliber water pipe, a vertical spiral wing type water meter is often adopted for flow measurement, and the specificity of the large-caliber water meter is often indicated. For better observation and control, a pressure measuring port is often arranged on the pipeline on two sides of the water meter so as to install a pressure sensor. However, the difficulty of drilling the pipeline is high, multiple processes are needed, the production cost is increased, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a perpendicular spiral shell wing formula water gauge of pressure port is got in watchcase apron area can be directly through this pressure port measurement pressure of getting, keeps the integrality of pipeline, reduces the technology step, improves production efficiency. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
A vertical spiral wing type water meter with a pressure tap on a meter shell cover plate comprises a meter cover seat, a counter, a meter shell cover plate, a flow guide frame, an impeller assembly and an impeller seat, wherein the counter is installed in the meter cover seat, the lower end of the meter cover seat is connected with the meter shell cover plate, the meter shell cover plate is fixed at the upper end of the meter shell to form a water flow cavity between the meter shell cover plate and the meter shell, the impeller assembly is arranged on the impeller seat and is wrapped by the flow guide frame, and the impeller assembly, the meter shell cover plate, the flow guide frame and the impeller seat are; the inner side of the watchcase cover plate is provided with a pressure measuring port which communicates the water flow cavity with the external space through a threaded hole.
Further, the pressure taking port is obliquely or vertically arranged.
Further, the threaded hole is formed in the top surface of the watchcase cover plate
Preferably, the threaded hole is vertically downwardly disposed.
(III) advantageous effects
Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, set up one on the watchcase apron and get the pressure mouth with the inside water gauge that is linked together, make water pressure directly lead to pressure sensor through this pressure mouth of getting, need not trompil on the pipeline, save the cost, improve production efficiency to get and press mouthful top to set up one and be used for sealed screw hole, can be sealed getting the pressure mouth under the condition that need not to install pressure sensor, prevent to leak.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 and 2, a vertical spiral-wing water meter with a pressure tap on a case cover plate comprises a case cover seat 1, a counter 2, a case cover plate 3, a flow guide frame 4, an impeller component 5 and an impeller seat 6, wherein the counter 2 is installed in the case cover seat 1, the case cover plate 3 is connected to the lower end of the case cover seat 1, the case cover plate 3 is fixed to the upper end of the case to form a water flow cavity 7 with the case, and the impeller component 5 is arranged on the impeller seat 6 and wrapped by the flow guide frame 4 and arranged in the water flow cavity 7.
The inner side of the watchcase cover plate 3 is provided with a pressure taking port 31, and the pressure taking port 31 is obliquely or vertically arranged and communicates the water flow cavity 7 with the external space. When the water pressure in the water meter needs to be measured, the water pressure in the water meter can be transmitted to the pressure sensor through the pressure taking port 31; in order to be suitable for the use condition of the non-pressure sensor, the top surface of the watchcase cover plate 3 is provided with a vertically downward threaded hole 32, and the pressure taking port 31 is used for communicating the threaded hole 32 with the water flow cavity 7; when the pressure sensor is not required to be installed, the threaded hole 32 may be sealed using a threaded seal to prevent water leakage.
The utility model discloses a design point lies in offering one on the watchcase apron and getting the pressure mouth with the inside water gauge that is linked together, makes water pressure directly lead to pressure sensor through this pressure mouth of getting, need not trompil on the pipeline, saves the cost, improves production efficiency to get and press mouthful top to set up one and be used for sealed screw hole, can be sealed with getting the pressure mouth under the condition that need not to install pressure sensor, prevent to leak.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
