Description

[0001] The present invention relates to a pipe fitting valve,

The present invention relates to a tube-use valve, more specifically, since a tightening section is formed in front of a body, not only a spanner but also a body can be easily tightened by using a buckle, It is possible to reduce the work time due to the construction and maintenance by inserting the wrench into the multiple groove portion formed in the tightening portion so as to reduce the work time and to easily make the disk and the spindle with the rack and the pinion And the spindle can be firmly and fixedly mounted without causing leakage in the connector through the coupling of the packing and the push nut. In addition, it is possible to prevent the handle from being released from the spindle during operation of the handle The present invention relates to a tube-mounted valve.

In general, an angle valve is a kind of stop valve, which acts to change the flow of fluid at right angles to match the direction of the inlet and the outlet. The angle valve is a cold / hot water pipe embedded in a toilet, a bathroom, So that the cold and hot water can be supplied to the water storage tank of the water receptacle or the toilet.

An angle valve for performing the above-described function is formed by connecting an inlet of an angle valve to a cold / hot water pipe connected through the inside of a building wall surface, and connecting an outlet of a sink and a sink or a storage tank of a toilet The supply hose is connected so that the water supplied from the cold / hot water pipe can be supplied to the water storage tank or the water storage tank of the toilet water through the operation lever provided on one side, or the water supply tank can be repaired or replaced And to cut off the supply of water through the operation of the operating lever when the user desires.

Such conventional techniques can be confirmed through the "Changed Angle Valve" of Korean Utility Model No. 20-0405517 and the "Angle Valve for Handling" of Korean Registered Patent No. 10-1090519.

However, in the above conventional techniques, since the operation lever for controlling the water supply is formed on the front surface, the tightening portion is formed in the middle portion of the body, and there is a problem in that it is difficult to tighten with a tool such as a spanner there was.

That is, in the case of installing in a narrow place such as a place where a toilet was installed, it was not only difficult to secure a space for operating the spanner, but even if the space was secured, the tightening could not be achieved when the angle of the wrench and the spanner did not match Therefore, there is a problem that the time required for construction is delayed.

Further, even when maintenance is required due to the breakage of the parts, it is difficult to separate the parts, so that there is a problem that the time required for the maintenance is much consumed.

It is an object of the present invention to provide a fastening device that can be easily fastened by using a wrench as well as a spanner by tightening the fastening portion at the front of the body and even if a work space is very narrow and a spanner or a box can not be used, And a wrench can be inserted into the polygonal groove formed in the female part so as to be tightened, thereby reducing the working time due to construction and maintenance.

In addition, the present invention can easily accomplish rack-to-pinion coupling by inserting a disk into the body through an inlet and then inserting the spindle into the body through a connecting port. In addition, when the rack and pinion are coupled, In which the pinion of the pinion is inserted into the slit hole formed in the disc, so that a stable operation is performed, thereby preventing a malfunction in opening and closing the opening and closing passage.

Further, according to the present invention, the spindle can be firmly and fixedly installed without causing leakage in the connector through the coupling of the packing and the pressing nut, and a polygonal protrusion and a fastening protrusion for fixing the handle are formed on the lower part of the pressing nut, And it is an object of the present invention to provide a tube-use valve capable of preventing the handle from being unwound from the spindle.

According to an aspect of the present invention, there is provided an air conditioner comprising: an inlet formed at a rear side to be connected to a cold and hot water pipe; an outlet formed at an upper side of the inlet tube to supply the fluid passing through the inlet tube to the connection tube; An opening / closing passage formed to connect the opening / closing passage and a connecting hole formed at the lower side to communicate with the opening / closing passage; A tightening part integrally formed in front of the body; A disk inserted into the inside of the body through an inlet port to open / close the opening / closing passage; A spindle which is coupled to the disk by a rack and a pinion to horizontally move the disk in the forward and backward directions according to the turning operation; A packing coupled to the spindle to prevent leakage of the connector; A push nut which is fastened to the connector and prevents the spindle from being attached and detached; And a handle coupled to a lower end of a spindle located outside of the body to rotate and control the spindle.

Since the fastening portion is formed at the front of the body, the tightening of the body can be easily accomplished by using the wrench as well as the spanner, and the work space is very small, It is possible to insert the wrench into the multiple groove portion formed in the tightening portion and tighten it, so that the working time due to the construction and the maintenance can be reduced.

In addition, the present invention can easily accomplish rack-to-pinion coupling by inserting a disk into the body through an inlet and then inserting the spindle into the body through a connecting port. In addition, when the rack and pinion are coupled, Is inserted into the slit hole formed in the disk and the stable operation is performed, there is an advantage that the malfunction of the opening and closing of the opening and closing passage can be prevented.

Further, according to the present invention, the spindle can be firmly and fixedly installed without causing leakage in the connector through the coupling of the packing and the pressing nut, and a polygonal protrusion and a fastening protrusion for fixing the handle are formed on the lower part of the pressing nut, There is also an advantage that the handle can be prevented from being unwound from the spindle.
