Technical Field
The invention relates to a valve preservation method, and belongs to the technical field of liquid control valves.
Background
A valve is a control device that is commonly used in everyday production and life.
Generally, the valve is not put into use immediately after being produced, but is stored for a period of time and then enters the hands of consumers through a certain distribution channel for use.
The existing valve storage method is to store the valve in a dry state directly in a storehouse, even more, store the valve in the open air, and the latter can accelerate the aging of the valve, shorten the service life of the valve, and even cause the damage of the valve; practice shows that even if the valve is placed in a warehouse for storage, the sealing rubber pad or rubber ring in the valve is gradually oxidized or aged, although the process is slow, the service life of the valve is virtually shortened, and the working reliability of the valve is also reduced.
In order to solve the problem, the existing measures are as follows:
1. shortening the valve holding time, which requires a reduction in production and an increase in sales, can result in production that cannot be continued and cannot be scaled up quickly, which is often done in workshop-type facilities.
2. The valves are simply packaged and then enter the storeroom, and the valves are inspected one by one before being delivered, so that the cost is undoubtedly increased, and after long-term storage, the sealing rubber pads or sealing rubber rings in the valves begin to be oxidized or aged, and the quality of the valves is reduced.
The prior art does not address the problem of conservation of valves effectively at low cost.

Detailed Description
The technical solution of the valve preservation method according to the present invention will be described in further detail with reference to the embodiments shown in the drawings.
In practice, when the valve is put into use, the sealing element in the valve cannot be oxidized or aged, or the oxidation or aging speed of the valve is further slowed, for example, in the case of the valve with the controlled liquid being water, after the valve is used for a period of time, the phenomenon that the performance of the silica gel sealing element is deteriorated does not occur.
Even if there is condensation in the valve interior resulting from evaporation or volatilization of the liquid being controlled, positive effects can be achieved on the preservation of the valve, such as helping to lubricate the moving parts within the valve, reducing oxidation or degradation of the seals within the valve, and preventing other debris from entering the valve.
For convenience, the liquid inlet 3 and the liquid outlet 2 are collectively referred to as a liquid inlet and outlet, and the liquid inlet pipe plug 5 and the liquid outlet pipe plug 4 are collectively referred to as a liquid inlet and outlet pipe plug.
As shown in fig. 1, a method for storing a valve, said valve being a valve 1 for controlling a flow of a controlled liquid, said valve 1 comprising a liquid inlet 3, a liquid outlet 2 and a valve interior chamber in which the controlled liquid is present during operation, is characterized in that: firstly, controlled liquid is arranged in a valve inner cavity of the valve 1, and then a liquid inlet pipe plug 5 and a liquid outlet pipe plug 4 are respectively arranged at a liquid inlet 3 and a liquid outlet 2 of the valve 1, so that the liquid inlet 3 and the liquid outlet 2 are blocked, and the controlled liquid is sealed in the valve inner cavity of the valve 1.
The volume of the controlled liquid disposed in the valve interior is no less than 5% of the volume of the valve interior.
When the valve inner cavity of the valve 1 comprises 2 and more inner chambers, a controlled liquid is respectively arranged in each inner chamber.
The volume of the controlled liquid disposed within each internal chamber is no less than 5% of the volume of each internal chamber.
As shown in fig. 2, a pilot-operated solenoid valve is used as an embodiment in the figure, and it can be seen from the figure that the inner cavity of the valve 1 comprises 3 inner cavities, the upper part of the flexible membrane main valve core 8 is a pilot cavity 9, the lower part of the flexible membrane main valve core 8 is an outlet main valve cavity 6 and an inlet main valve cavity 7, the inlet main valve cavity 7 is communicated with the liquid inlet 3, the outlet main valve cavity 6 is communicated with the liquid outlet 2, each valve inner cavity has a sealing element, and in order to achieve a good preservation effect, a controlled liquid is respectively arranged in each inner cavity.
In the process of preserving the valve, the liquid inlet pipe plug 5 and the liquid outlet pipe plug 4 are not damaged, and the ability of tolerating the controlled liquid is found to be stronger by the plastic material in practice, so the material of the liquid inlet pipe plug 5 and the material of the liquid outlet pipe plug 4 are the same as the material of the liquid inlet 3 and the material of the liquid outlet 2 of the valve 1.
The preservation temperature of the valve is controlled in a reasonable range without harmful effect on the valve, considering factors such as altitude and check valve, the upper temperature limit of the preservation valve 1 is the highest temperature when the controlled liquid is kept in a liquid state under the condition of not exceeding the highest working temperature of the valve 1 and 0.6 times to 2 times of standard atmospheric pressure, the lower temperature limit of the preservation valve 1 is not lower than the lowest working temperature of the valve 1 and the lowest temperature when the controlled liquid is kept in a liquid state under the condition of 0.6 times to 2 times of standard atmospheric pressure, taking the controlled liquid as water for example, the water can be frozen by too low temperature, and further harmful effect can be generated on the valve.
When the valve 1 has not less than 1 inlet 3 or not less than 1 outlet 2, all the inlets 3 are respectively sealed by inlet pipe plugs 5, and all the outlets 2 are respectively sealed by outlet pipe plugs 4, so that the controlled liquid is sealed in the valve cavity of the valve 1, as shown in fig. 3, a certain valve 1 with 4 liquid inlets and outlets is provided, and all the liquid inlets and outlets are respectively sealed by the liquid inlet and outlet pipe plugs.
The technical procedures of the invention for plugging the liquid inlet 3 and the liquid outlet 2 of the valve 1 are combined with the inspection technical procedures, in the test procedure of the valve 1, the valve 1 is normally switched in the controlled liquid under nominal conditions and the valve 1 is actuated several times, in order to test the performance of the valve 1, therefore, the preservation method of the valve 1 requires that the valve inner cavity of the valve 1 is filled with the controlled liquid firstly, and then after the valve 1 is repeatedly operated for a plurality of times, namely, after the inspection process program of the valve 1 is finished, the controlled liquid is left in the valve inner cavity of the valve 1, and then the process program for plugging the liquid inlet 3 and the liquid outlet 2 of the valve 1 is executed, thereby not only combining the existing inspection process program, but also the controlled liquid can be filled into each gap of the valve cavity of the valve 1 as much as possible, which has positive effect on the preservation, the sale and the use of the valve 1.
The plugging mode of each liquid inlet and outlet port of the invention is suitable for fully utilizing the connection mode of each liquid inlet and outlet port and other pipe fittings, for example, if each liquid inlet and outlet port is connected with other pipe fittings through threads, each liquid inlet and outlet port is suitable for plugging by installing a liquid inlet and outlet port pipe plug in a threaded connection mode, and if each liquid inlet and outlet port is connected with other pipe fittings through a plurality of bolts, each liquid inlet and outlet port is suitable for plugging by installing a liquid inlet and outlet port pipe plug in a mode of connecting a plurality of bolts.
After the valve preservation method is adopted, the preservation effect of the valve is effectively improved, the valve is very convenient to preserve and transport, the original procedure of removing the residual controlled liquid after inspection is cancelled, the production period is shortened, the production cost is reduced, the positive technical effect is generated, and the effect is deeply confirmed by vast consumers.
Of course, there are other alternatives and developments and equivalent means that we can envision without departing from the framework of the invention.
