Description

Valve opening improved structure

The new type relates to the field of solenoid valves, in particular to an improved valve opening structure, which can be mainly by simplifying the number of parts, and integrating the relevant foolproof structure on the key switch, which can be driven synchronously through the opening and closing of the switch. Under the switching of the state, it can also maintain a closed environment.

In general, commercially available solenoid valves usually design an additional independent mechanism to open and close according to the valve's opening and closing status. Common mechanisms are usually depressurized or pushed back in the displacement direction, so that the iron core inside the solenoid valve is displaced, allowing the valve to move. is on.

The follow-up is to repeatedly press or push the valve in the opposite direction to close the valve. Although this design can achieve the purpose of safety and foolproofness, in the current actual operation, the user needs to operate a single solenoid valve. When the overall number is too large , the time consuming will be considerable.

In addition to occupying part of the volume of the solenoid valve, the aforementioned valve opening structure also increases the number of parts, and the assembly to the solenoid valve becomes more complicated. Therefore, the creator has learned from the practical application and research of the aforementioned conventional structure. , it still has shortcomings that must be improved.

The main purpose of this new model is to provide an improved valve opening structure, by integrating the structural parts of the valve opening into the button, thereby reducing the overall number of parts, so that the valve can still maintain an airtight state when opening and closing. .

The technical features of this new type of solution include: a valve body, which is mainly composed of a front part and a rear part connected, an iron core is arranged inside the front part, and a buffer part is passed through the iron core and presses the rear part to form a valve , a button is accommodated inside the rear part, and an elastic member is arranged on the inner side of the button;

A push rod is arranged in the rear part with an insert groove, and the insert groove can be inserted by a limiting member to limit the displacement distance of a button, so that the elastic member cooperates with the push rod to form a retractable state for the button The push rod can be driven to move the iron core by pressing means, and the airtight state can be maintained synchronously.

A second technical purpose is to set a recess at the side edge of the button, the recess is symmetrically designed, and can be inserted into the limiting member.

The second technical purpose is, wherein the elastic key is a kind of spring.

With the above-mentioned innovative and unique design, compared with the prior art, the present invention can use a push rod to cooperate with an elastic member to be arranged inside the button, so that when the button is pressed to open or close the valve, it can still maintain an airtight state, and can be optimized. number of parts, and the complexity of reducing assembly locations.

Usually according to the present creation, the best feasible embodiment, and the detailed description in conjunction with the drawings 1 to 7, to increase the understanding of the new model, the new model is an improved valve opening structure, which includes: a valve body (10) , which is mainly composed of a front part (20) connected with a rear part (30), the inner space of the front part (20) can provide an iron core (22) to be arranged therein, and one end of the iron core (22) wears a buffer member (23) Pressing the rear part (30) to form a valve (21), the buffer part (23) can also increase the sealing effect due to the assembly of the front part (20) and the rear part (30), and the rear part (30) A button (31) is accommodated in the inner space, and an elastic member (32) is further arranged on the inner side of the button (31);

In accordance with the content shown in Figure 3, a recess (311) is provided at the side edge of the aforementioned button (31), and the recess (311) is symmetrically designed, mainly for the insertion of the limiting member (302), more specifically : After the limiting member (302) is inserted into the recess (301) corresponding to the rear part (30) together with the recess (311), the button (31) can be restricted by the displacement distance.

A push rod (33) is arranged inside the rear part (30) with a socket (301), and the elastic member (32) cooperates with the push rod (33) to form a retractable state for the button (31). ) can push the push rod (33) to drive the iron core (22) to displace by pressing means, and can maintain the airtight state synchronously.

Please refer to as shown in Figures 5 to 7, wherein Figure 6 is a state where the button (31) is pressed, which will drive the push rod (33) to produce displacement in the direction of the front part (20), further pushing the iron core (22), the valve (21) will be opened at this time, allowing the relevant fluid to pass through.

When the button (31) is pressed again, the push rod (33) will be displaced in the direction of the rear part (30), and the iron core (22) at this time will be affected by the elastic force and return to its original position, which also makes the valve (21) Close; whether the valve (21) is open or closed, the button (31) is assembled with the push rod (33) through the elastic member (32), so as to keep the fluid passing through it from being discharged in reverse flow. This keeps the airtight state.

To sum up, in this improved structure for opening the valve, the push rod (33) and the elastic member (32) are arranged inside the button (31), so that when the button (31) is pressed to open or close the valve, the air can be maintained. dense state, and can optimize the number of parts and reduce the complexity of the assembly location.
