Abstract
The utility model discloses a valve that possesses water gauge anti-idle function, including the valve body shell, set up the valve gap on the valve body shell, threaded connection establishes the valve rod on the valve gap, and the valve rod front end is provided with the case, be provided with compression spring on the valve rod, compression spring's both ends are contradicted respectively on case and valve gap. The utility model has the advantages of it is following and effect: through set up compression spring and sealing washer in the key position, this combination valve can still keep the leakproofness of case water inlet after long-term the use, avoids taking place the seepage scheduling problem. The combined valve has the characteristics of high durability and leakage prevention, can avoid idling of the water meter, and prolongs the stable service life of the combined valve.
Description
Technical Field
The utility model relates to the technical field of valves, in particular to valve that possesses water gauge anti-idle function.
Background
The prior Chinese patent with the application number of CN201621151677.6 of the company discloses a gate valve check combination valve, which comprises a valve body shell with a water inlet and a water outlet, and a valve cover which is connected with the valve body shell in a threaded manner; the valve shell and the valve body cover are enclosed to form a valve core cavity, the bottom of the valve core cavity is provided with a valve core water inlet communicated with the water inlet, and the side surface of the valve core cavity is provided with a valve core water outlet communicated with the water outlet; wherein the water inlet of the valve core is connected with a valve core in a matching way, and the valve core is sealed in the valve core cavity; the valve cover is in threaded connection with a valve rod, and the valve rod can be abutted to the valve core to reach the water inlet of the valve core and is sealed. The utility model discloses a gate valve and anti-idle valve organic "unite two into one", have the non-nursing, maintenance efficiency is high, reduces advantages such as energy consumption.
However, in the actual use process, the leakage problem between the valve core and the water inlet of the valve core is found, so that the check effect of the combined valve cannot be effectively realized; and simultaneously, the problem of idle running of the water meter is easily caused, and extra loss is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can reduce the seepage to prevent the valve of water gauge idle running.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a valve that possesses water gauge anti-idle function, includes the valve body shell, sets up the valve gap on the valve body shell, and threaded connection has the valve rod on the valve gap, and the valve rod front end is provided with the case, be provided with compression spring on the valve rod, compression spring's both ends are contradicted respectively on case and valve cover.
Further setting the following steps: the upper inner wall of the valve cover is provided with a cylindrical body, and the compression spring is sleeved on the cylindrical body.
Further setting the following steps: the area of the upper surface of the valve core is larger than the cross-sectional area of the cylindrical body.
Further setting the following steps: the lower end of the valve core is provided with a lower cambered surface with an inverted trapezoid cross section, the lower cambered surface is provided with an annular groove, and a sealing ring is arranged in the annular groove.
To sum up, the utility model discloses following beneficial effect has: through set up compression spring and sealing washer in the key position, this combination valve can still keep the leakproofness of case water inlet after long-term the use, avoids taking place the seepage scheduling problem. The combined valve has the characteristics of high durability and leakage prevention, and can avoid idle running of the water meter so as to reduce extra loss.
Drawings
Fig. 1 is a schematic diagram of a valve structure.
In the figure: 1. a valve body housing; 2. a valve cover; 3. a valve stem; 4. a valve core; 5. a compression spring; 6. a cylindrical body; 7. a lower arc surface; 8. an annular groove; 9. and (5) sealing rings.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The valve with the water meter idling prevention function comprises a valve body shell 1, wherein a valve cover 2 is arranged on the valve body shell 1, and a cylindrical body 6 with a circular cross section is arranged on the inner wall above the valve cover 2. A valve core 4 water inlet is arranged in the valve body shell 1. The valve cover 2 is provided with a valve rod 3 through threaded connection, the lower end of the valve rod 3 is provided with a valve core 4, and the section of the lower end of the valve core 4 is an inverted trapezoidal lower cambered surface 7.
The cylindrical body 6 is sleeved with a compression spring 5, and the other end of the compression spring 5 is abutted against the valve core 4. The upper surface area of the valve element 4 is larger than the cross-sectional area of the cylindrical body 6, so that the compression spring 5 can be kept stable. Compression spring 5 can contradict case 4 to avoid not hard up and the problem of the seepage that probably causes between case 4 and the valve rod 3, guarantee the stability of the non return effect of this gate valve non return combination valve.
An annular groove 8 is formed in the lower arc surface 7, a sealing ring 9 is arranged in the annular groove 8, and the sealing ring 9 can further increase the sealing effect of the position, so that the leakage problem is avoided. And meanwhile, the problem of idle running of the water meter is solved, and extra loss is avoided.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
