Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a two-way electromagnetic valve. Background Art
[0002] The two-way solenoid valve is a step-by-step direct pilot solenoid valve. It can be divided into a normally closed solenoid valve and a normally open solenoid valve according to the different open and closed states when the power is off. When the power is on, the internal electromagnetic coil generates electromagnetic force to lift the closing piece from the valve seat, and the valve opens. When the power is off, the electromagnetic force disappears, the spring presses the closing piece onto the valve seat, and the valve closes.
[0003] A threaded structure is designed at the inlet and outlet of the solenoid valve, and threaded joints or threaded pipe fittings are used to fix the pipeline and the solenoid valve through threaded connection. In a pipeline system that needs to operate for a long time or withstand high pressure, the threaded connection is easily affected by external vibration and loosens, resulting in the stability of the connection being affected.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] See also Figures 1 to 4The utility model provides a technical solution: a two-way solenoid valve, comprising a solenoid valve body 1, and valve ports 101 arranged at both ends of the solenoid valve body 1. Two symmetrically distributed supports 2 are fixedly connected to the solenoid valve body 1, and two bidirectional screw rods 3 are rotatably inserted on the supports 2. A knob 6 is fixedly connected to one end of the bidirectional screw rod 3, and two symmetrically distributed internal thread sleeves 5 are threadedly sleeved on the bidirectional screw rod 3. A guide rod 4 is embedded in the support 2, and the guide rod 4 is movably penetrated through the support 2. A base block 7 is fixedly installed at the other end of the internal thread sleeve 5, and an arc clamping plate 8 is fixedly connected to the end of the base block 7. Two arc clamping plates 8 are used to clamp and fix the pipeline. Rubber pads can be arranged on the inner side walls of the arc clamping plates 8, which helps to increase the friction during clamping, so that the clamping of the pipeline is more stable; the rubber pads can reduce the direct contact between the arc clamping plates 8 and the pipeline, thereby reducing the chance of damage or wear. This helps to extend the service life of the arc clamping plates 8 and the pipeline.
[0024] First, one end of the pipe is threadedly inserted into the valve port 101, which is a threaded connection method in the prior art; then the knob 6 is turned to drive the bidirectional screw 3 to rotate, and the bidirectional screw 3 drives the two internal threaded sleeves 5 to approach each other, and finally the two arc-shaped clamping plates 8 are close to each other, and the arc-shaped clamping plates 8 are in contact with the outer circumferential side wall of the pipe, so as to further reinforce the pipe, effectively reduce the possibility of loosening or displacement of the pipe, thereby improving the safety of the working environment; thereby extending the service life of the pipe and related equipment; stable pipe connection can reduce the wear of components such as pipes and valves, and reduce maintenance and replacement costs.
[0025] In this solution, a slot 501 is provided at one end of the internal threaded sleeve 5, an insert block 9 is fixedly connected to one end of the base block 7, the insert block 9 is inserted into the slot 501, and the end of the internal threaded sleeve 5 and the insert block 9 are fixedly installed by bolts 10. The internal threaded sleeve 5 is L-shaped as a whole, and the slot 501 is horizontally arranged.
[0026] The plug block 9 can be separated from the slot 501, so that the arc clamp 8 can be detached and replaced individually when the arc clamp 8 is severely worn without removing the entire clamping device; and the arc clamp 8 of appropriate size can also be selected according to the size of the connected pipe, which has a wider range of applications and meets the needs.
[0027] In addition, the slot 501 is a rectangular slot and the insert block 9 is a rectangular block. The shapes and structures of the two are matched to ensure that the slot 501 can guide the insert block 9, and the insert block 9 can only move along a straight line in the slot 501 without deflection.
[0028] In addition, a screw hole 901 is provided on the plug block 9, and the threaded end of the bolt 10 is arranged in the screw hole 901. A plug hole is provided on the top of the slot 501, and the bolt 10 passes through the plug hole. In this way, the plug block 9 and the end of the internal threaded sleeve 5 can be fixed and installed by the bolt 10.
