Description
Technical Field
The utility model relates to a cylinder valve technical field specifically indicates straight-through valve in the cylinder valve.
Background
The straight-through valve has the characteristics of convenient connection and gas leakage prevention, the gas source end of the straight-through valve is in threaded connection with the steel cylinder, the gas end is in quick plug connection with the pipeline, and the valve body of the straight-through valve is internally provided with a one-way valve for preventing gas from leaking. The top core is arranged in the plug-in connector of the pipeline, and the top core can push the one-way valve core open to keep normal gas consumption during plugging. In order to further enhance the capability of preventing gas leakage, an opening and closing valve is additionally arranged in the valve body close to the gas source end. For example, the spherical straight valve disclosed in application publication No. CN107701753A, the spherical straight valve additionally arranged can effectively solve the problems of residual gas leakage and gas leakage caused by abnormal one-way valve when the gas source is replaced. However, since the valve core of the spherical straight valve is a sphere, the processing of the matching surfaces of the valve seat and the valve core requires spherical surface processing, which has the problems of high process precision and high processing and assembling difficulty, resulting in high cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a straight valve that can reduce the processing degree of difficulty and cost.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a camshaft opens and close straight valve, including the valve body, the air supply end of valve body establishes into the screwed joint with steel bottle threaded connection, establishes the plug that is connected with the pipeline plug with the air supply end, and installation check valve in the valve body of close proximity air supply end installs stop valve, its characterized in that in the valve body of close proximity air supply end: the stop valve comprises a valve seat, a plunger type valve core, a cam shaft, a hand wheel, an installation seat and a spring, wherein the plunger type valve core moves in a reciprocating mode opposite to the valve seat, the cam shaft is installed on the side portion of the valve body and drives the plunger type valve core to move in a reciprocating mode, the hand wheel rotates the cam shaft, the installation seat is used for installing the plunger type valve core in a sliding mode, and the spring keeps the plunger type valve core moving towards the valve seat.
On the basis, the valve body comprises a gas source section valve body and a gas section valve body which are in threaded connection.
Adopt the utility model discloses the beneficial effect who brings: because the utility model discloses straight valve has installed the plunger type stop valve of opening and close by the camshaft additional, and the processing of plunger type case and disk seat fitting surface need not spherical surface machining, can cut the reality and reduce the machining precision and the assembly degree of difficulty, effective reduction in production cost.
Drawings
Fig. 1 is the structural schematic diagram of the camshaft open/close straight valve of the present invention.
Detailed Description
As shown in figure 1, the camshaft open-close straight valve comprises a valve body 1, wherein a gas source end of the valve body 1 is provided with a threaded connector 1.1 in threaded connection with a steel cylinder, a gas end is provided with a plug connector 1.2 in plug connection with a pipeline, a check valve 2 is installed in the valve body 1 close to the gas end, and a stop valve is installed in the valve body close to the gas end. The utility model discloses in, the stop valve including disk seat 3 and, facing to disk seat 3 reciprocating motion's plunger type case 4, install 1 lateral part drive plunger type case 4 reciprocating motion's of valve body camshaft 5, the hand wheel 6 of rotating camshaft 5, the mount pad 7 of slidable mounting plunger type case 4 and keep plunger type case 4 to move to disk seat 3 trend's spring 8.
It will be appreciated that the valve seat 3 is a sleeve seat providing a valve bore. The plunger type valve core 4 mainly comprises a plunger head and a plunger rod, wherein a sealing gasket 9 for plugging a valve hole is arranged on the plunger head, and the plunger rod is provided with a transverse elongated hole for penetrating and installing the camshaft 5 so as to ensure that a cam part of the camshaft 5 rotates in the elongated hole. The spring 8 can maintain the closing movement tendency of the plunger type valve core 4. When the stop valve needs to be opened, the hand wheel is rotated towards the opening direction to drive the cam shaft 5 to rotate, the cam shaft 5 drives the plunger type valve core to move away from the valve seat 3, and the valve hole is unblocked. When the stop valve is closed, the hand wheel is rotated in the opposite direction, and along with the rotation of the cam shaft 5, the spring 8 pushes the plunger type valve core 4 to move towards the valve seat 3 until the valve seat 3 is pressed, and the valve hole is blocked. The spring 8 reduces friction between the cam and the plunger rod when the shut-off valve is closed to avoid frictional damage and affecting the closing of the shut-off valve.
For convenience of processing and assembling, the valve body 1 comprises a gas source section valve body 1.3 and a gas section valve body 1.4 which are connected through threads. Thus, the valve seat 3 can be clamped between the gas source section valve body 1.3 and the gas section valve body 1.4, and a sealing ring is additionally arranged. The mounting seat 7 is in threaded connection with the valve body 1.3 of the air source section to form a tube seat 7.1 for slidably inserting the plunger rod of the plunger type valve core 4, and the spring 8 is arranged in the tube seat 7.1 and abuts against the plunger rod.
