The utility model relates to the field of machine manufacturing, in particular to an integrated pressure reducing valve bank.
Background
The pressure reducing valve is a valve which automatically keeps the outlet pressure stable by reducing the regulating inlet pressure to a certain required outlet pressure and relying on the energy of the medium. Some occasions require a plurality of pressure reducing valves and other valves to form a pressure reducing valve group; the existing pressure reducing valve group is formed by splicing and combining a plurality of valves, the valves are connected by flanges, and the valve group is long in length and not suitable for being installed in narrow and limited space.
There is a need for an integrated pressure relief valve assembly with a shorter length, fewer leakage points, and a lower cost, which can be installed in a small space, to solve the above-mentioned technical problems.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides an integrated pressure reducing valve bank which is shorter in length, less in leakage point, lower in cost and capable of being installed in a narrow space.
The utility model solves the technical problems by the following technical scheme:
the utility model provides an integrated pressure reducing valve bank which comprises an upstream gate valve, a filter, a downstream gate valve and a main valve of a water control valve; the water outlet end of the upstream gate valve is connected with the water inlet end of the main valve of the water control valve, and the filter is arranged on a flow pipeline between the upstream gate valve and the main valve of the water control valve; the water outlet end of the main valve of the water control valve is connected with the water inlet end of the downstream gate valve; the water inlet end of the upstream gate valve is provided with a flange surface, and the water outlet end of the downstream gate valve is provided with a flange surface; the upstream gate valve, the filter, the main valve of the water control valve and the downstream gate valve are of an integrated structure.
In the utility model, the upstream gate valve and the downstream gate valve are conventional in the field, and the existing gate valve is connected with a main valve through a flange and a pipeline;
preferably, the upstream gate valve and the downstream gate valve are located at the same height.
In the utility model, the main valve of the water control valve is conventional in the field, and the closing and the opening and the closing of the whole valve group are realized through the main valve.
In the present invention, the filter is conventional in the art;
preferably, the filter is a three-stage filtering device;
preferably, the distance between the filter and the water outlet of the upstream gate valve is 1/3-1/2 of the distance between the filter and the water inlet of the main valve of the water control valve;
preferably, the main valve of the water control valve and the downstream gate valve are connected by welding.
The working principle of the integrated pressure reducing valve group is as follows: the product is installed on a line, an upstream gate valve is opened to allow medium to flow, the medium flows through a filter, flows into an upper valve cavity of a main valve of a water control valve through a guide pipe, reaches a pilot valve, and can flow to the downstream smoothly due to the fact that pressure does not exist at the downstream, at the moment, the pressure of the upper cavity of the main valve of the water control valve is small, the pressure of the lower cavity is large, and the medium pushes a main valve disc open to flow to the downstream. If the pressure of the pilot valve is set to be 1, when the downstream pressure is increased to 1, the pressure applied to a diaphragm in the pilot valve closes a flow passage in the pilot valve, at this time, the upper cavity pressure of the main valve of the water control valve cannot be discharged, and the upper cavity pressure and the lower cavity pressure converge, but because the upper cavity pressure-bearing area is larger, the upper cavity can apply more force downwards to the valve disc under the same pressure condition, so that the valve disc downwards closes the main valve of the water control valve, and the valve group is closed.
The positive progress effect of the utility model is as follows: the integrated pressure reducing valve bank has the advantages of shorter length, fewer leakage points, reduced cost and capability of being installed in a narrow space, and compared with the conventional pressure reducing valve bank with the same component, the integral length of the integrated pressure reducing valve bank is reduced by 20-40%.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the present embodiment provides an integrated pressure relief valve set, which includes an upstream gate valve 1, a filter 2, a downstream gate valve 4, and a main valve 3 of a water control valve; the water outlet end of the upstream gate valve 1 is connected with the water inlet end of the main valve 3 of the water control valve, and the filter 2 is arranged on a flow pipeline between the upstream gate valve 1 and the main valve 3 of the water control valve; the water outlet end of the main valve 3 of the water control valve is connected with the water inlet end of the downstream gate valve 4; the water inlet end of the upstream gate valve 1 is provided with a flange surface, and the water outlet end of the downstream gate valve 4 is provided with a flange surface; the upstream gate valve 1, the filter 2, the main valve 3 of the water control valve and the downstream gate valve 4 are of an integrated structure.
In the embodiment, the right end flange of the upstream gate valve 1 and the left end flange of the downstream gate valve 4 are removed, so that the connection length is reduced, and leakage points are reduced; the upstream gate valve 1 and the downstream gate valve 4 are at the same height.
In this embodiment, the filter 2 is a three-stage filtering device; the distance between the filter 2 and the water outlet of the upstream gate valve 1 is 1/2 the distance between the filter 2 and the water inlet of the main valve 3 of the water control valve; the main valve 3 of the water control valve and the downstream gate valve 4 are connected through welding.
The working principle of the integrated pressure reducing valve group of the embodiment is as follows: the product is installed on a line, an upstream gate valve is opened to allow medium to flow, the medium flows through a filter, flows into an upper valve cavity of a main valve of a water control valve through a guide pipe, reaches a pilot valve, and can flow to the downstream smoothly due to the fact that pressure does not exist at the downstream, at the moment, the pressure of the upper cavity of the main valve of the water control valve is small, the pressure of the lower cavity is large, and the medium pushes a main valve disc open to flow to the downstream. If the pressure of the pilot valve is set to be 1, when the downstream pressure is increased to 1, the pressure applied to a diaphragm in the pilot valve closes a flow passage in the pilot valve, at this time, the upper cavity pressure of the main valve of the water control valve cannot be discharged, and the upper cavity pressure and the lower cavity pressure converge, but because the upper cavity pressure-bearing area is larger, the upper cavity can apply more force downwards to the valve disc under the same pressure condition, so that the valve disc downwards closes the main valve of the water control valve, and the whole valve group is closed.
The integral type pressure reducing valve unit of this embodiment length is shorter, the leakage point is still less, the installation in the narrow and small space can be realized, compare in the pressure reducing valve unit of current same part, the whole length of the device of this embodiment has reduced 35%.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
