Abstract
The utility model discloses a flow valve which is used for civil spiralism type water meter by water supply industries. An annular convex area (2) is arranged in a circular valve body (1). A guide valve block (3) is arranged in the valve body (1). The guide valve block (3) is provided with a groove (4). A water inlet (5) is arranged in the groove (4). A central overflow frame (6) is fixed in the valve body (1). One end of the central overflow frame (6) is sheathed with a spring (7) and inserts into the guide valve block (3). The other end of the central overflow frame (6) is connected with a flexible pipe (8). A connecting meter attachment plug (9) is arranged on the flexible pipe (8). The connecting meter attachment plug (9) is provided with a water outlet. The flow valve solves the losing water problem caused by the low sensitivity of the water meter, and the problem chronically obsesses water supply industries. The flow valve has the advantages of low cost, convenient installation, etc.
Description
Technical field: the utility model relates to the volume control device of the measurement instrument, particularly domestic water meter of water supply industry use.
Background technology: the domestic water meter that uses is all based on the Spiralism type water meter at present, this water meter sensitivity is low, water is from the impeller by-pass flow when weep or drip are lower than the initiating flow, impeller can not be worked, cause a large amount of losses to water supply industry,, upgrade high sensitivity water meter and cause a large amount of wastes on the one hand so existing water meter can not satisfy the requirement of water supply industry, of a high price on the other hand, water supply industry is also unable to be born.
Summary of the invention: the purpose of this utility model provides and a kind ofly can improve water meter sensitivity, prevents that water meter from leaking the watermeter flowing rate valve of meter.
The purpose of this utility model is achieved in that in the circular valve body an annular protrusion, be provided with the guide valve piece in the valve body, the guide valve piece is provided with groove, water inlet is arranged in groove, and the center is crossed the water support and is fixed in the valve body, and the end that the water support is crossed at the center is with spring, and insertion guide valve piece, the other end is connected to flexible pipe, has one to connect the table plug on the flexible pipe, a water delivering orifice is arranged on the plug connecing table.
One end of described valve body is provided with screen pack.
The utility model is with less input, existing water meter sensitivity and accuracy are improved, from measuring the water user steals water with rill, drip the method that solves, the water yield that has effectively stoped leakage, promote the water supply industry normal development, the policy that solves shortage of water resources with economic leverage that makes that country formulates is achieved, and advantage such as it is low to have a cost, easy to use.
Description of drawings: Fig. 1 is the structural representation of this watermeter flowing rate valve.
Embodiment: as can be known from Fig. 1, one annular protrusion 2 is arranged in the valve body 1 of the utility model circle, guide valve piece 3 is arranged in the valve body 1, guide valve piece 3 is provided with groove 4, water inlet 5 is arranged in groove 4, the center is crossed water support 6 and is fixed in the valve body 1, and the end that water support 6 is crossed at the center is with spring 7, and inserts guide valve piece 3.The other end is connected to flexible pipe 8, has one to connect table plug 9 on the flexible pipe 8, a water delivering orifice is arranged on the plug 9 connecing table.During use this flow valve is installed to the water inlet end of water meter, will connects the impeller intake that table plug 9 inserts water meter, the water inlet that screen pack is installed to flow valve gets final product.When discharge is lower than the initiating flow of water meter, spring 7 promotes guide valve pieces 3 and valve body 1 interior annular protrusion 2 and contacts and block normal water inlet, water flows into flexible pipe 8 from the water inlet 5 of the groove 4 of guide valve piece 3, the water that gathers directly promotes wheel rotation by the water delivering orifice 10 that connects on the table plug 9, when normal water, because the acting force of water makes guide valve piece 3 with spring 7 compressions, the center is crossed water support 6 and is blocked water inlet 5 on the guide valve piece 3, and water flows through around guide valve piece 3.
Claims (2)
1, a kind of watermeter flowing rate valve, it is characterized in that: in the circular valve body (1) annular protrusion (2) is arranged, be provided with guide valve piece (3) in the valve body (1), guide valve piece (3) is provided with groove (4), water inlet (5) is arranged in groove (4), the center is crossed water support (6) and is fixed in the valve body (1), the end that water support (6) is crossed at the center is with spring (7), and insertion guide valve piece (3), the other end is connected to flexible pipe (8), have one to connect table plug (9) on the flexible pipe (8), a water delivering orifice is arranged connecing on table plug (9).
2, watermeter flowing rate valve according to claim 1 is characterized in that: an end of described valve body (1) is provided with screen pack.
