FIG. 1 is a view showing the state of use of the shock sensing lock spring valve according to the embodiment of the present invention, and FIG. 2 is a sectional view for explaining the structure of the shock sensing lock spring valve according to the embodiment of the present invention.

The shock sensing lock spring valve 100 according to the embodiment of the present invention includes the support member 110, the blocking member 120, the compression spring 130, and the restraint member 115 And is installed in the middle of a pipe (P) such as a gas pipe, an oil pipeline, and a water pipe, so that the oil can be quickly shut off in response to an impact in various sudden situations including earthquakes.

As a result, it is possible to eliminate the fear of fire or explosion caused by gas or oil leakage due to damage or breakage of piping, or flooding caused by leaking tap water.

The shock-sensing lock spring valve according to the embodiment of the present invention can be easily configured without using expensive parts such as a sensor, thereby minimizing installation cost and enabling stable operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, shock-sensing lock spring valves according to embodiments of the present invention will be described in detail with reference to the respective components.

The support member 110 includes a plate-shaped base portion 111 for supporting all the components, a connection portion for connecting the pipe P in a spaced state to allow the barrier member 120 to intervene A supporting part 113 for supporting the blocking member 120 so as to be movable forward and backward and a vertical supporting part 114 for supporting the restricting member 115.

The connection portion 112 is supported on the top surface of the base portion 111 and connected to the pipe P in a state where the pipe P is spaced apart from the pipe P, Hole 112a. The supporting part 113 is formed on the upper surface of the intermediate part of the base part 111 and has a support hole 113a formed toward the advancing / retreating hole 112a of the connecting part 112 as shown in the figure. The supporting hole 113a of the supporting part 113 allows the blocking member 120 to pass therethrough. Meanwhile, the vertical support part 114 is vertically erected in the form of a square column at the rear end of the base part 111, so that the restraint member 115 is supported to be able to ascend and descend.

The blocking member 120 intervenes in the spaced space between the pipe P and the pipe P to control the flow of the fluid through the pipe P. [ The blocking member 120 is formed of a bar body 121 which is provided so as to be able to move back and forth through a support hole 113a formed in a supporting portion 113 of the supporting member 110. The blocking member 120 includes a front end portion 121a And a ring-shaped protrusion 122 protruding along the outer circumferential surface of the body 121 to prevent the compression spring 130 from moving forward. The blocking member 120 thus constructed advances in the advancing / retreating hole 112a of the connecting portion 112 of the supporting member 110 when the leading end portion 121a of the blocking member 120 advances to block the separated portion between the pipe P and the pipe P, The distal end portion of the support member 110 retracts from the retreat hole 112a of the connection portion 112 of the support member 110 to allow the flow of the fluid through the pipe P .

An O-ring 125 is provided at the front end 121a of the body 121 of the blocking member 120 to prevent the fluid from flowing out through the forward and backward holes of the connection part 112. [

A ball bearing 123 is fixed to the rear end 121b of the body 121 of the blocking member 120 by a nut 124 in a state where the ball bearing 123 is inserted. When the ball bearing 123 is installed, the restricting member 115 restrains the blocking member 120 from advancing in a manner that the locking protrusion 115c of the restricting member 115 engages the ball bearing 123 It becomes possible. Here, it should be noted that a ball bearing 123 is provided instead of a protrusion protruding from the blocking member 120. When the ball bearing 123 is installed, the inner and outer rings of the ball bearing 123 are rotated relative to each other while the blocking member 120 is rotated by the restraint member 115 while being restrained by the restricting member 115, The relative rotational displacement between the member 115 and the restricting member 115 can be completely solved because of the rotational displacement between the blocking member 120 and the restricting member 115. [ Particularly, in the case of the ball bearing 123, products of various sizes are sold, so that it is not necessary to separately manufacture a custom-made member detachable from the rear end of the body 121 of the blocking member 120, .

The compression spring 130 urges the protrusion 122 of the blocking member 120 by elastic force in a state of being supported by the support portion 113 while the body 121 of the blocking member 120 is being wrapped, So that the blocking member 120 has a tendency to advance.

The restricting member 115 is installed on the vertical supporting portion 114 positioned at the rear end of the base portion 111 of the supporting member 110 and the bearing 123 of the blocking member 120 is hooked, 120 to prevent the blocking member 120 from being restrained and allowing the blocking member 120 to advance when the shock or vibration is applied. For this, the restraint member 115 includes a vertical part 115a which is vertically coupled to the upper end of the vertical support part 114 of the support member 110 and a vertical part 115a which is formed long in the forward direction from the upper end part of the vertical part 115a, And a horizontal portion 115b having a locking protrusion 115c protruding downward to hook the bearing 123 of the blocking member 120. [ The vertical portion 115a of the restraining member 115 is a hollow member corresponding to the outer side of the vertical support portion 114 formed in the shape of a quadrangular prism and is installed to be vertically movable with respect to the vertical support portion 114. A bolt 115d is additionally provided to fix the vertical portion 115a of the restraining member 115 to the vertical support portion 114. [

The operation of the shock sensing lock spring valve according to the present invention will now be described in detail with reference to FIGS. 3A to 3C.

3A, the flow of the fluid through the pipe is allowed in a state where the blocking member 120 is retracted. At this time, the compression spring 130 is compressed between the support portion 113 of the support member 110 and the protrusion 122 of the blocking member 120 so as to tend to advance the blocking member 120, The restricting member 115 restrains the rear end bearing 123 of the blocking member 120 from being advanced by the blocking member 120 in a dry state.

Thereafter, when an impact is transmitted from the outside due to an earthquake or the like, a slight relative displacement occurs between the bearing 123 of the blocking member 120 and the locking protrusion 115c of the locking member 115 as shown in FIG. 3B, The constraint for the automatic release is released.

3C, the blocking member 120 rapidly advances due to the elastic force of the compression spring 130, so that the tip end portion 121a of the blocking member 120 blocks the flow path of the pipe P. As a result, The flow of the fluid is shut off.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
