Connecting method of lock cap and bonnet in magnetic locking valve

Abstract

The invention provides a connecting method of a lock cap and a bonnet in a magnetic locking valve, and belongs to the technical field of valves. The connecting method solves the problem that an existing magnetic locking valve is inconvenient to install while increasing the effective connection area, the connecting method comprises the following steps that when parts are prepared, an annular grooveis machined in the inner wall of a connecting hole, the end part of a positioning head is machined into a tapered guide part with a taper, and the annular groove is machined in the side part of the positioning head below the tapered guide part, and a guide hole is machined into a inverted cone shape; when a clamp spring is installed, the clamp spring is arranged in the guide hole, a guide sleeveis placed on the inverted lock cap, and the clamp spring is punched into the annular groove in the lock cap from the guide sleeve in an inward contraction manner by using a punch of punching equipment; and when the lock cap and the bonnet are connected, the lock cap is placed on the bonnet, and the lock cap is pressed down by using the punching equipment to enable the tapered guide part to penetrate through the clamp spring. The connecting method has the advantages of convenient installation, high qualification rate, firm connection and the like.

Description

technical field

[0001] The invention belongs to the technical field of valves and relates to a magnetic lock valve, in particular to a method for connecting a lock cap and a valve cap in the magnetic lock valve. Background technique

[0002] With the rise of residential intelligent management, magnetic lock valves have been more and more widely used. The magnetic locking valve is actually a magnetic lock. Its principle of use is to set a magnetic locking mechanism on the valve. The magnetic locking mechanism can lock the valve stem inside the valve and cannot rotate. At the same time, it must be equipped with a A key that unlocks the magnetic locking mechanism.

[0003] At present, there are many types of magnetic lock valves with different structures, and the more common structure on the market is a valve with a magnetic lock disclosed by the patent application number 200920313315.6, which includes a valve body, a bonnet and a hand wheel. There is a valve core and a valve...

Examples

Embodiment 1

[0047] The connection method between the lock cap and the bonnet in the magnetic lock valve, such as Figure 4 As shown, the connection method includes the following steps:

[0048] a. Prepare parts: Prepare lock cap 1, bonnet 2, circlip 3, guide sleeve 4, positioning block 5, magnetic steel 6, spring 8 and pin 7. Each part can be produced by itself or outsourced according to demand, and each part must meet the following conditions:

[0049] like figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the circlip 3 is a regular notched ring and its fracture is a square surface; the center of the lower end of the lock cap 1 is provided with a connecting hole 1a, and an annular groove 1a1 is processed on the inner wall of the connecting hole 1a near the opening, and the upper end of the lock cap 1 A connection hole 1c connected to the connection hole 1a is provided inside, the connection hole 1a is a round hole, the connection hole 1c ...

Embodiment 2

[0057] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, a straight hole is also provided in the guide sleeve 4, and the diameter of the straight hole is the same as the minimum diameter of the guide hole 4a. The upper port communicates with the lower port of the guide hole 4a.

Embodiment 3

[0059] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, in step a, the lock cap 1, the valve cap 2 and the snap spring 3 are prepared, and the lower end of the lock cap 1 has a connection hole 1a The opening of the connection hole 1a is processed into a guide section 1a2 that expands outwards and has a taper, and an annular groove 1a1 is processed on the inner wall of the connection hole 1a above the guide section 1a2. The upper end of the valve cap 2 has a The positioning head 2a processes the end of the positioning head 2a into a conical guide portion 2b with a taper, and processes a ring groove on the side of the positioning head 2a below the tapered guide portion 2b, and the snap ring 3 is a regular notched ring, The inner diameter of the circlip 3 is between the maximum outer diameter and the smallest outer diameter of the tapered guide part 2b, the maximum outer diameter of the guide ...
