Description

  The present invention relates to a protective cover for a gas stopper, and more particularly to a protective cover for a gas stopper that protects the gas stopper from external heat or impact.

A gas plug body with a pipe housing part that connects the gas pipe to both sides and opens upward, and a gas pipe body that is pivotably housed in the gas pipe housing part. In the gas stopper provided with the operation knob to be operated, a gas flow path is formed from one connection cylinder part to the other connection cylinder part through the inside of the thread housing part. In addition, the gas insertion hole is penetrated in the thread.
The thread accommodating portion has a tapered inner peripheral surface that expands in the upward direction, and the thread is formed in an inverted truncated cone shape having a tapered outer peripheral surface along the tapered inner peripheral surface. It is common. When the operation knob is rotated, the thread rotates in the thread accommodating part while sliding the tapered outer peripheral surface thereof to the tapered inner peripheral surface of the thread accommodating part. The road is opened and closed.

If the gas plug with the above configuration is exposed to direct sunlight outdoors, or is exposed to oil or hot water heated in the kitchen, or is affected by radiant heat, the outer gas plug body is housed inside. The temperature rises before the spiral, and this causes thermal expansion. If the diameter of the thread accommodating portion is expanded as a result of the thermal expansion of the gas plug main body first, the accommodated thread will sink to the smaller diameter side of the thread accommodating section. In this state, when the spiral expands following the gas plug main body, the spiral penetrates into the spiral accommodating portion.
If such a situation is repeatedly performed over a long period of time, there is an inconvenience that it becomes difficult to operate the terminal with the operation knob.

In order to solve the above inconvenience, a cover for covering the gas stopper main body as shown in Patent Document 1 has been devised.
By covering the gas stopper body with the cover, heat from direct sunlight can be cut off, the temperature rise of the gas stopper body is moderated, and no significant temperature difference occurs between the gas stopper body and the core. Therefore, it is possible to prevent the above-described inconvenience that the thread bites into the thermally expanded thread accommodating portion as described above and becomes inoperable.

  However, in the thing of the said patent document 1, a cover has a special shape fixed to the protrusion part provided in the surface of the gas stopper main body, and the shape and dimension of a cover are match | combined with the shape and dimension of a gas stopper main body. Since it must be set, it cannot be attached to the existing gas plug body. Further, in the conventional cover described above, the gas plug body is covered and protected, but the operation knob is not covered, so there is a disadvantage that a protective cover for protecting the operation knob must be provided separately.

  The present invention provides a gas plug main body in which a connecting tube portion to which a gas pipe is connected communicates coaxially with both sides of a screw housing portion, and is rotatably accommodated in the screw housing portion and accommodated from one connection tube portion. A gas plug provided with an operation knob that pivotally attaches to the open end of the thread housing part and pivots the thread to open and close the gas flow path leading to the other connecting cylinder part through the part. "Protective cover for gas stopper for protection" makes it easy to attach to an existing gas stopper, and can be installed with its orientation changed in a direction that is easily affected by external heat, impact, etc. It is an object to provide a protective cover for a gas stopper.

The solution of the present invention taken in order to solve the above-mentioned problems is, “A gas pipe or an attachment part that can be attached to the connection tube part,
A protective plate disposed so as to cover at least one side of the gas stopper and the top surface side of the operation knob;
It consists of a connecting member that connects the mounting portion and the protective plate,
The protection plate can be moved back and forth or rotated in the direction of the gas flow path with respect to the attachment portion via the connecting member.

The above means operates as follows.
An attachment part is directly attached and fixed to a pair of connecting cylinder parts or gas pipes connected to the pair of connecting cylinder parts projecting on both sides of the pipe housing part of the existing gas stopper. The protective plate is provided so as to cover at least one side of the entire gas stopper composed of the gas stopper main body including the connection cylinder portion and the operation knob and the top surface side of the operation knob, and the attachment portion via the connecting member. Connected.
At this time, considering the installation location and position of the gas stopper and the environment around the gas stopper, attach the protective plate to the mounting part so that the gas stopper is positioned in a direction that is susceptible to external heat and impact. On the other hand, the protective plate is positioned at a predetermined position or a predetermined posture with respect to the gas plug by moving forward and backward along the gas flow path or by rotating the connecting portion with the connecting member as a rotation fulcrum. can do. Further, if the operation knob is set so that it can be exposed to the outside by advancing / retracting movement or rotation of the protection plate, the protection plate will not interfere with the operation of the gas stopper.

In the gas stopper protective cover, “the connecting member is integrally provided on either the mounting portion or the protective plate, and can be connected to either the other side so as to move forward / backward or rotate”. desirable.
Since the connecting member is integrally provided on either the mounting part or the protective plate, the connecting member is attached to the gas pipe or the connecting tube part, and the connecting member is moved back and forth to either the mounting part or the protective plate. Alternatively, the protective plate can be attached to an existing gas stopper so as to be able to advance and retreat, or to rotate freely, by performing the operation of attaching it so as to be rotatable.

  In the above gas stopper protective cover, "the heat insulating material is provided on the inner surface facing the gas stopper side of the protective plate" or "the heat insulating coating is applied to the outer surface of the protective plate" In this case, the gas stopper can be effectively protected against the influence of heat from direct sunlight or flame.

  In the gas stopper protective cover, it is desirable that “the protective plate is made of a metal plate having a substantially U-shaped or substantially U-shaped cross section covering both sides of the gas stopper and the top side of the operation knob”. In this case, since almost the entire gas plug can be covered with a protective plate made of a metal plate, the entire gas plug can be reliably protected without damage to the protective plate due to heat or external impact.

For example, a gas stopper in a commercial kitchen may be installed in an environment where it is exposed to radiant heat from commercial gas equipment or oil or hot water heated with use of the kitchen equipment. Therefore, the mounting portion of the protective cover for the gas stopper of the present invention is attached to the connecting tube portion of the gas stopper and the gas pipe connected thereto, and the protective plate is mounted so as to be positioned in the direction affected by heat. Advancing / retreating or rotating with respect to the part is positioned at a predetermined position and a predetermined posture. As described above, the protective cover can be easily attached to the existing gas stopper, and at least one side of the gas stopper including the gas stopper main body and the operation knob in which the thread is accommodated and the top of the operation knob. The surface side can be reliably protected from radiant heat or heated oil or hot water.
Since the protective plate can be moved back and forth or rotated with respect to the mounting portion via the connecting member, the position and orientation of the protective plate can be adjusted even after installation on the gas plug, and the environment surrounding the gas plug can be changed. In addition, since the operation knob can be exposed from the protective cover during the operation of the gas stopper, a user-friendly gas stopper cover can be provided.

If the protective plate is provided with a heat insulating material or is provided with a heat insulating coating, the gas plug can be reliably protected from heat by the protective plate.
Further, when the protective plate is formed of a metal plate having a substantially U-shaped or U-shaped cross section, both sides of the gas stopper and the top surface side of the operation knob are protected in a manner surrounded by the protective plate. In addition to being protected from radiant heat in the kitchen and heat from heated oil and hot water, in the case of gas plugs installed outdoors, it is also protected from heat from direct sunlight, rain, sea breeze, and external impacts. Can be protected. Therefore, it is effective against rust prevention and damage.
