Description

Technical Field

[0001] The utility model mainly relates to the technical field of valves, in particular to a sleeve type valve. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] There are many types of valves. Valves usually need to be connected to other equipment or other valves outside due to installation or use requirements. The traditional valve connection method uses internal and external threads for connection, which is slow and not stable enough. On this basis, and in order to meet the diversified development of the market, a ferrule valve is proposed. Utility Model Content

[0028] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference Figure 1-2 , this embodiment provides a sleeve type valve, including a valve housing 1;

[0031] A self-closing joint set 2 is arranged at one axial end of the valve housing 1;

[0032] The handle assembly 3 is arranged at a radial end of the valve housing 1 and away from the self-closing joint set 2;

[0033] The rotating shaft 4 is driven by the handle assembly 3 to rotate;

[0034] The valve flap 5 is limitedly slidable in the valve housing 1, and the valve flap 5 is transmission-connected to the rotating shaft 4 through a transmission assembly 6;

[0035] Wherein, the transmission assembly 6 includes

[0036] A crankshaft block 61 connected to the rotating shaft 4;

[0037] An S hook 62, one end of which is connected to the crankshaft block 61 and the other end of which is hinged to the valve disc 5;

[0038] The transmission assembly 6 drives the valve flap 5 to slide in the valve housing 1 to achieve rapid installation of the valve.

[0039] The present embodiment also includes a positioning device 7 arranged on one side of the rotating shaft 4. The specific structure of the positioning device 4 is not limited in the present embodiment. For example, a block, a pin, etc. are used to prevent the handle assembly 3 from driving the rotating shaft 4 to rotate. The positioning device 7 needs to be removed or moved so that the handle assembly 3 can drive the rotating shaft 4 to rotate. By providing the positioning device 7 for restriction, a better error prevention, dust prevention, and disengagement effect is achieved.

[0040] In a preferred embodiment, in the self-closing joint set 2, a steel ball 8 is extruded in the valve housing 1, and the steel ball 8 allows the valve to be quickly connected to an external device or other valves.

[0041] In a preferred embodiment, in the self-closing joint set 2, a connection seal 9 is provided in the valve housing 1. When connecting to other external devices or other valves, the connection seal 9 plays a good sealing role.

[0042] In a preferred embodiment, a main seal 10 is provided between the valve flap 5 and the valve housing 1. The main seal 10 ensures the sealing performance of the valve when it is connected to other external devices or valves.

[0043] The operation process of the utility model is as follows:

[0044] like Figure 2As shown, when an external device or valve is needed, the positioning device 7 releases the restriction on the rotating shaft 4, and the rotating shaft 4 is driven to rotate by rotating the handle 3 assembly. During the rotation of the rotating shaft 4, the crankshaft block 61 is driven to rotate. The rotation of the crankshaft block 61 causes the S hook 62 to move in a certain arc, driving the valve disc 5 to move inward. At this time, the external device or valve is connected to one end of the self-closing joint set, and the seal is quickly connected and installed through the steel ball 8.

[0045] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and all adopt the existing technology. At the same time, the content of the above background technology belongs to the technical cognition scope of the utility model inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute the prior art.

[0046] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
