Description

Technical Field

[0001] The invention relates to the technical field of endoscope valves, in particular to an attitude-adjustable endoscope valve assembly. Background Art

[0002] In previous products, for example: Chinese patent with announcement number CN221170847U discloses a left-right universal endoscope valve, which belongs to the field of valve technology. The key points of its technical solution are: it includes a valve body, a connection port 1 for connecting to an alarm valve is provided on the valve body, a pressure relief port for installing a pressure relief device is provided on the valve body, a valve cavity is provided in the valve body, a connection port 2 and a connection port 3 are provided on the valve body, the pressure relief port, connection port 1, connection port 2 and connection port 3 are all connected to the valve cavity, a switch component 1 for controlling the connection and disconnection between connection port 2 and the valve cavity is provided on the valve body, a switch component 2 for controlling the connection and disconnection between connection port 3 and the valve cavity is provided on the valve body, and a endoscope is provided on the valve body, the endoscope is tilted on the valve body and the central axis of the endoscope points to the valve cavity.

[0003] In the application of this type of sight glass valve, we found that it is installed in fire protection pipelines, especially when installed on the main fire valve. One end of the sight glass valve is connected to the main fire valve and hung out, and the other end is connected to the fire protection pipeline. The fire protection pipeline is distributed at the top of the house and has branches. The vertical branch pipeline can be connected to this sight glass valve. In order to meet fire protection requirements and safety considerations, the pipeline here is made of metal pipes. Of course, PPR water pipes are also used. Metal water pipes have high structural strength and have great application advantages.

[0004] Now considering completing the connection between the pipeline and the interface on the endoscope valve, we found that the endoscope valve, whose overall structure cannot be deformed, is in a hanging posture due to its own gravity and is connected to the side of the fire valve. It is easily squeezed at the threaded connection, resulting in unreliable threaded connection and low installation efficiency. It is difficult to align the upper and lower installation interfaces during installation. Therefore, this structure needs to be improved. Utility Model Content

[0005] In order to solve the above-mentioned technical problems and shortcomings: how to improve the installation efficiency and applicability reliability of the endoscope valve assembly, the present invention provides a posture-adjustable endoscope valve assembly.

[0006] To achieve the above-mentioned and other related purposes, the present invention adopts the following technical solutions:

[0007] A posture-adjustable sight glass valve assembly comprises a sight glass valve unit, a bellows, and a ball valve unit. The sight glass valve unit comprises a three-way valve body, a ball valve switch, a transparent lens, a retaining spring, and a sealing ring. A water inlet interface is provided at one end of the three-way valve body. The ball valve switch is mounted on the three-way valve body near the water inlet interface. The ball valve switch is used to control the on / off of the water inlet interface. Windows are provided on both sides of the rear of the ball valve switch on the three-way valve body. Sealing grooves are provided at the edges of the windows. The sealing ring is embedded in the sealing groove and is abutted by the transparent lens. The transparent lens seals the window. The edge of the transparent lens is fixed to the window by a retaining ring.

[0008] The upper end of the three-way valve body is connected to the ball valve monomer through a bellows.

[0009] Preferably, a flow port is provided in the three-way valve body, and the outlet side of the flow port is conical.

[0010] Preferably, the ball valve switch includes a handle, a valve stem, a ball core and a seal. The ball core is assembled in the three-way valve body, and the ball core contacts the inner wall of the three-way valve body through the seal. The valve stem is also inserted into the ball core, and the valve stem passes through the three-way valve body and is sealed with the three-way valve body through the seal. A stud is also provided on the three-way valve body, and the stud is threaded with the three-way valve body and its end contacts the rotation axis of the ball core.

[0011] Preferably, the bellows provides a range of motion for up and down telescopic adjustment and left and right offset.

[0012] Preferably, the three-way valve body is further provided with a detection hole, a detection light is threadedly fixed to the detection hole, and the detection light emits light into the three-way valve body, and the detection light is located between two transparent lenses.

[0013] Preferably, the detection light is connected to a battery and a switch via a wire, and the switch is a key switch or a human body sensing switch.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. Compared to the existing sight glass valve structure where multiple ball valve switches are integrated into one valve body, which causes inconvenience in installation and cannot share gravity after hanging installation, the solution of this application utilizes the flexibility of the bellows to separate the sight glass valve unit and the ball valve unit. This not only allows water to flow between them, but also facilitates installation and overcomes the gravity problem, reducing the gravity load on the sight glass valve unit and transferring the force on the ball valve unit to the fire protection pipe connected to the ball valve unit.

[0016] 2. Since the position of the interface can be adjusted freely, it is easier to align the mirror valve unit and the ball valve unit, thereby improving the assembly effect;

[0017] 3. The transparent lens can be reliably sealed and allows users to observe whether there is water flow inside. The built-in detection light can also be used to further improve the effect of peeking inside the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0026] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component can be changed at will, and the component layout may also be more complex.

[0027] The specific implementation manner of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 、 Figure 2 and Figure 3 As shown, the present invention discloses an adjustable-position endoscope valve assembly, comprising an endoscope valve unit 1, a bellows 2, and a ball valve unit 3. The endoscope valve unit 1 comprises a three-way valve body 11, a ball valve switch 12, a transparent lens 13, a retaining ring 14, and a sealing ring 15. A water inlet port 16 is provided at one end of the three-way valve body 11. The ball valve switch 12 is mounted on the three-way valve body 11 near the water inlet port 16. The ball valve switch 12 is used to control the on / off of the water inlet port 16. Windows 17 are provided on both sides of the rear of the ball valve switch 12 on the three-way valve body 11. Sealing grooves are provided at the edges of the windows 17. The sealing ring 15 is embedded in the sealing grooves and is abutted by the transparent lens 13. The transparent lens 13 seals the window 17. The edge of the transparent lens 13 is fixed to the window 17 by a retaining ring. The upper end of the three-way valve body 11 is connected to the ball valve unit 3 via the bellows 2.

[0030] During installation, we generally install the water inlet interface 16 of the mirror valve unit 1 on the side of the fire valve, and then install the ball valve unit 3 on the fire pipeline. At this time, the fire pipeline can carry the weight of the ball valve unit 3, and the weight of the mirror valve unit 1 is supported by the fire valve. In addition, due to the adjustment of the bellows 2 during installation, the posture of the mirror valve unit 1 or the ball valve unit 3 can be slightly changed, thereby improving assembly efficiency. Compared with the solution of hard-connecting the ball valve unit 3 and the mirror valve unit 1, this solution has obvious advantages.

[0031] To control the internal flow and prevent excessive flow or impact on the reliability of the transparent lens 13, a flow port 18 is used to control the water flow. The three-way valve body 11 is provided with a flow port 18, and the outlet side of the flow port 18 is tapered. This tapered structure allows the water flow to be divided and guided.

[0032] Specific, combined Figure 3 and Figure 4The ball valve switch 12 includes a handle 121, a valve stem 122, a ball core 123, and a seal 124. The ball core 123 is assembled in the three-way valve body 11. The ball core 123 contacts the inner wall of the three-way valve body 11 through the seal 124. The valve stem 122 is also inserted into the ball core 123. The valve stem 122 passes through the three-way valve body 11 and is sealed with the three-way valve body 11 through the seal 124. The three-way valve body 11 is also provided with a stud 125. The stud 125 is threadedly engaged with the three-way valve body 11 and its end contacts the rotation axis of the ball core 123. The handle 121 can be rotated to realize the rotation of the valve stem 122, thereby driving the rotation of the ball core 123. The rotation of the ball core 123 realizes the switching of the water flow. There is a channel on the ball core 123. If the channel is facing the pipeline channel in the valve body, water will flow; otherwise, the water flow channel will be closed. The function of stud 125 is to improve the reliability of the movement of ball core 123. Stud 125 is located at the rotation center of ball core 123, which can extend the service life of ball core 123.

[0033] In this solution, the bellows 2 provides a range of motion for upward and downward telescopic adjustment and left and right offset. The bellows 2 is made of stainless steel corrugated soft and can be bent appropriately.

[0034] Example 2:

[0035] refer to Figure 5 As shown, based on the above-mentioned embodiment 1, it can be further preferred that a detection hole 19 is further provided on the three-way valve body 11, and a detection light 4 is screwed to the detection hole 19. The detection light 4 emits light into the three-way valve body 11, and the detection light 4 is located between two transparent lenses 13. The detection light 4 is an LED lamp, which consumes very little power and can be used for a very long time. The detection light 4 is connected to the battery 5 and the switch through a wire, and the switch is a push button switch or a human body sensing switch. If the switch is a push button switch, it can be manually controlled. When the user needs to observe the internal situation of the three-way valve body 11, the detection light 4 is turned on to achieve lighting, and the internal situation can be observed through the transparent lens 13 of the endoscope valve unit 1. If the switch is a human body sensing switch, the detection light 4 can be turned on when the human body approaches, and the detection light 4 can be turned off when the human body moves away.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, any equivalent variations based on the structure, shape, or principles of the present invention are intended to be within the scope of protection of the present invention.
