Abstract

The utility model relates to a marine fast valve that closes especially relates to a marine fast valve that closes. The utility model has the advantages that: the user can manual handle, makes the handle rotate, and the handle can drive the screw thread piece and rotate, and the sheathed tube lug inserts in the spout simultaneously, can restrict sheathed tube rotation, and consequently the screw thread piece drives the sleeve pipe and removes along the spout to sleeve pipe and No. one pole fixed connection, No. one pole and No. two poles pass through the cylindric lock and fix in L shape logical groove, No. two pole fixed connection case, consequently rotate the handle and just can control case closed valve pocket export or open the export. The valve is closed through the rotating handle, multiple times of rotation are needed, and the speed is low. When the valve needs to be quickly closed, the second rod and the valve core are driven to move through the cylindrical pin, and the valve can be quickly closed.

Description

Marine quick-closing valve

Technical Field

The utility model relates to a marine fast valve that closes especially relates to a marine fast valve that closes.

Background

In a fuel conveying pipeline of a marine main engine, when an emergency occurs, a medium in the pipeline needs to be cut off quickly. There is a need for a valve that can be quickly closed to allow quick closing action to be achieved. The quick closing action is driven by compressed air available anywhere on a ship, the compressed air is efficient, energy-saving, reliable and environment-friendly, and remote control operation can be realized, so the valve is called a pneumatic quick closing valve for the ship, and is hereinafter referred to as a quick closing valve. The marine quick-closing valve needs to be capable of quickly closing the valve.

The utility model discloses a realize through following technical scheme:

the utility model provides a marine fast valve that closes, which comprises a valve body, the inside valve pocket that is equipped with of valve body, the valve pocket is equipped with import and export, be equipped with the case in the valve pocket, case fixed connection valve rod, the valve rod includes No. one pole and No. two poles, No. one the pole is equipped with the blind hole, No. two poles insert in the blind hole, No. two pole fixed connection case, No. two pole fixed connection cylindric lock, No. one the pole is equipped with L shape and leads to the groove, the cylindric lock passes L shape and leads to the groove, the valve body is equipped with the through-hole, No. one the pole passes the through-hole, valve body fixed connection outer tube, the through-hole is relative with the export, through-hole intercommunication outer tube is inside and the valve pocket, No. one pole fixed connection sleeve pipe, sheathed tube hole is equipped with the internal thread.

According to the above technical scheme, preferably, the outer tube is provided with a through groove, and the cylindrical pin extends out of the through groove.

According to the above technical solution, preferably, the through hole is provided with a sealing ring.

According to the above technical solution, preferably, the end of the outer tube is provided with an end cap.

The utility model has the advantages that: the user can manual handle, makes the handle rotate, and the handle can drive the screw thread piece and rotate, and the sheathed tube lug inserts in the spout simultaneously, can restrict sheathed tube rotation, and consequently the screw thread piece drives the sleeve pipe and removes along the spout to sleeve pipe and No. one pole fixed connection, No. one pole and No. two poles pass through the cylindric lock and fix in L shape logical groove, No. two pole fixed connection case, consequently rotate the handle and just can control case closed valve pocket export or open the export. The valve is closed through the rotating handle, multiple times of rotation are needed, and the speed is low. When the valve needs to be quickly closed, the second rod and the valve core are driven to move through the cylindrical pin, and the valve can be quickly closed.

Drawings

Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.

Fig. 2 shows a schematic structural diagram of a cross section of a casing according to an embodiment of the present invention.

In the figure: 1. the valve comprises a valve body, a valve cavity, an inlet, an outlet, a valve core, a rod, a through hole, a sleeve and a sleeve, wherein the valve body comprises 2 parts of the valve cavity, 3 parts of the inlet, 4 parts of the outlet, 5 parts of the valve core, 6 parts of the rod, 7 parts of the rod, 8 parts of a cylindrical pin, 9 parts of an L-shaped through groove, 10 parts of the through hole, 11.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the marine quick-closing valve comprises a valve body 1, a valve cavity 2 is arranged in the valve body, the valve cavity is provided with an inlet 3 and an outlet 4, a valve core 5 is arranged in the valve cavity, the valve core is fixedly connected with a valve rod, the valve rod comprises a first rod 6 and a second rod 7, the first rod is provided with a blind hole, the second rod is inserted into the blind hole, the valve comprises a second rod fixedly connected valve core, a second rod fixedly connected cylindrical pin 8, a first rod is provided with an L-shaped through groove 9, the cylindrical pin penetrates through the L-shaped through groove, a valve body is provided with a through hole 10, a first rod penetrates through the through hole, a valve body fixedly connected outer tube 11 is opposite to an outlet, the through hole is communicated with the interior of the outer tube and a valve cavity, a first rod fixedly connected sleeve 12 is arranged in an inner hole of the sleeve, the sleeve is connected with a threaded block 13 through threads, the threaded block is fixedly connected with a rotating handle 14, the outer wall of the sleeve is provided with a convex block 15, the inner wall of the outer tube is provided with a sliding.

The working principle of the embodiment is as follows: the user can manual handle, makes the handle rotate, and the handle can drive the screw thread piece and rotate, and the sheathed tube lug inserts in the spout simultaneously, can restrict sheathed tube rotation, and consequently the screw thread piece drives the sleeve pipe and removes along the spout to sleeve pipe and No. one pole fixed connection, No. one pole and No. two poles pass through the cylindric lock and fix in L shape logical groove, No. two pole fixed connection case, consequently rotate the handle and just can control case closed valve pocket export or open the export.
