Description

Improved copper core seat structure of valve body

This creation is a modification of the copper core seat structure of the valve body, especially a thinned inner convex ring, which makes the plastic bonding line smoother and more compact, without the benefit of leakage.

The conventional valve body structure, as shown in Figures 1, 2 and 3, comprises a body 10, two water stop rings 11, 14 , a ball valve 12, a copper mandrel 13, a set of tubes 15 and a The valve body 16 is composed of a valve body 16; wherein the body 10 is a hollow pipe body, and the upper end is provided with a copper mandrel base 130, which is formed as a pivot hole 103 which penetrates and protrudes from the body 10 to form a convex ring. The first ring 101 and the second block 102 are perpendicular to each other. The ball valve 12 is provided with a coupling groove 121 and a flow channel 122. The two ends of the ball valve 12 are respectively opposite to the water stop rings 11 and 14. The copper mandrel 13 is provided with a leakage preventing ring 131, a joint end 132 and a positioning ring 133. The copper mandrel 13 is self-retained from the inside to the outside. The insertion portion 133 is fastened to the bottom end of the pivot hole 103. The leakage preventing ring 131 tightly blocks the copper mandrel 13 and the pivot hole 103. The coupling groove 121 of the ball valve 12 can be embedded. The combined end 132 and the ball valve 12 and the copper mandrel 13 are integrally rotated; the set of tubes 15 is a hollow tubular body and the body 10 is screwed, and the two waterstops 11, 14 and the ball valve 12 are forced into one body; The valve handle 16 is provided The hole 161 is bored, and the copper mandrel 13 is locked on the convex ring 104 by the nut 17 to rotate the valve stem 16 and the copper mandrel 13 integrally, and the rotation angle thereof is affected by the first block 101 and the second block 102. By the above, the force-rotating valve handle 16 can drive the copper mandrel 13 and turn the ball valve 12 to an angle, which can form a valve body for passage or open circuit, and the valve stem 16 is optimally opened and closed. The first stop 101 and the second stop 102 are presetly limited; however, the above structure actually has the following disadvantages:

(1) The convex ring 104 and the first stopper 101 and the second stopper 102 are integrally molded with the main body 10 to ensure that the convex ring 104 having the pivot hole 103 has a certain durability and can withstand the valve handle 16 . The external force of the copper mandrel 13 is driven, and the first stopper 101 and the second stopper 102 are coupled and supported, and the thickness thereof is often thickened, and the convex ring 104, the first stopper 101 and the second stopper 102 can be enhanced. The endurance strength, but neglecting the increase of the thickness of the convex ring 104, will make the bonding line D1 (also known as the weld line) due to the large amount of plastic, slow down the welding speed and lengthen the fusion time, resulting in a temperature drop and the bonding line D1 is not The gap is flat, and the gap is large and cannot be filled by the leakage preventing ring 231, so that the leakage preventing ring 131 between the pivot hole 103 and the copper mandrel 13 leaks, and when the valve handle 16 is changed, the valve body passage or the circuit is broken. When the high-pressure fluid flows through the water-stopping rings 11 and 14 and the cross-section of the flow path 122 of the ball valve 12 to the pivot hole 103, the leakage often occurs, the maintenance is troublesome, and the resources are wasted, and the user is rather inconvenient. .

(2) The first stopper 101 and the second stopper 102 are provided to provide an abutment limit of the opening and closing positions of the valve handle 1, and are required to withstand the impact of the user on the metal material handle 16, and the first stopper 101, The second block 102 is only connected to the convex ring 104 in a corner area, and the durability is not good. It is easier to oxidize the plastic after a period of use, and is more likely to be damaged by external force.

The reason is that, in view of the above-mentioned many shortcomings, the creator has increased the anti-leakage effect of the convex ring 104 of the copper mandrel seat 130 and provided a durable and more reinforced block structure, and has been studied in detail and accumulated for many years in the valve body related industry. The development and manufacturing experience has finally produced this creation.

The main purpose of the present invention is to solve the above problems, and to provide an improved copper core seat structure of the valve body, which has better adhesion and strength. The main technology and purpose is: one of the purposes of the present invention is the inner convex ring 204. The thinning is adopted, thereby reducing the amount of the plastic formed by the inner convex ring 204, and increasing the plastic flow rate relatively, thereby ensuring that the bonding line D2 of the inner convex ring 204 is more flat and does not cause leakage.

Another purpose of the present invention is that the outer convex ring 205 is spaced and annularly disposed on the outer circumference of the inner convex ring 204, and is integrally formed integrally with the first stopper 201 and the second stopper 202, thereby assisting in strengthening the first stopper 201. The second stopper 202 is subjected to the impact of the valve handle 26 due to the opening and closing action, so that the endurance is not damaged.

In order to make the reviewer have a better understanding of the creation, a preferred embodiment and a diagram are described in detail. For example, please refer to Figures 4 to 7. The valve system comprises a body 20 and a water stop ring 21, 24, a ball valve 22, a copper mandrel 23, a set of tubes 25 and a valve handle 26, wherein the body 20 is a hollow tube body, the upper end of which is provided with a copper mandrel holder 230, which has a through body The ball valve 22 is provided with a coupling groove 221 and a flow path 222. The two ends of the ball valve 22 are closely attached to the water stopping rings 21 and 24, respectively, and the flow path 222 can be smoothly circulated or closed. The copper mandrel 23 is provided with a leakage preventing ring 231, a joint end 232 and a positioning ring 233. The copper mandrel 23 protrudes from the inner and outer self-retaining holes 203, and the positioning ring 233 is fixed to the pivot hole 203. At the bottom end, the leakage preventing ring 231 tightly compresses the copper mandrel 23 and the pivot hole 203. The coupling groove 221 of the ball valve 22 can be fitted into the joint end 232, and the ball valve 22 and the copper mandrel 23 are integrally rotated. The set pipe 25 is a hollow pipe body and is screwed into the body 20, and the two water stop rings 21, 24 and the ball valve 22 are forced to be integrated; the valve handle 26 is provided with a through hole 261 and is fitted with a screw 27, the copper mandrel 23 is locked, and the valve handle 26 is integrally rotated with the copper mandrel 23, and the rotation angle thereof is limited by the first stopper 201 and the second stopper 202; wherein the copper mandrel base 230 is pivoted The hole 203 extends perpendicularly through the body 20 and protrudes from the body to form an inner convex ring 204. The inner convex ring 204 is provided with an outer convex ring 205 at an outer circumference. The inner convex ring 204 and the outer convex ring 205 have a spacing and the same height. The inner convex ring 204 is set to be thinner, thereby reducing the amount of the molded plastic that is emitted from the inner convex ring 204, relatively increasing the plastic flow rate and high-temperature fusion, and ensuring that the bonding wire D2 of the inner convex ring 204 is more flat; the outer convex ring 205 is provided with each other. The first first block 201 and the second block 202 are connected to one body. The copper mandrel 23 passes through the group of holes 203 and protrudes from the inner ring 204 to make the valve handle 26 and copper. When the mandrel 23 rotates integrally, the valve handle 26 can abut against the first stopper 201 and the second stopper 202, thereby assisting the reinforcement of the first stopper 201 and the second stopper 202 to withstand the opening and closing of the valve stem 26 The impact.

With the above configuration, the thinned inner convex ring 204 can ensure the bonding line D2 Although it has a relatively small gap, it can be elastically tamped by the leakage preventing ring 231 to prevent the valve body from leaking. The outer convex ring 205 can reinforce the strength of the first stopper 201 and the second stopper 202. To make the valve body structure more durable and practical.

The composition of this creation, the details are as follows: as shown in Figures 4 to 7, this creation The body 20, the inner convex ring 204, the outer convex ring 205 and the pivot hole 203 are integrally molded by a hot-melt plastic material, and the inner flange 204 is thinned, so that the hot-melt state can be ensured during the injection molding process. The flowing plastic fills the thinned inner ring 204 at a relatively fast speed to ensure that the plastic temperature is not cooled, and the plastic bond line D2 forms a flat bond line D2. When the high pressure fluid passes through the water stop rings 21, 24 and the ball valve 22 flow path 222 When the cross-section flows to the pivot hole 203, the leak-proof ring 231 between the inner ring 204 and the copper mandrel 23 is tightly closed, so that the high-pressure fluid does not leak.

Moreover, when the user applies a force to pull the valve handle 26 to drive the copper mandrel 23, the binding end 232 The coupling groove 221 of the valve body 22 is driven to open and close the valve body 22, and to ensure the optimal operation position when the valve handle 26 is opened or closed, the second block 201 and the second block 202 are resisted. The side of the valve handle 26 is a parallel or vertical valve body, and is integrally coupled by the convex ring 205 around the inner convex ring 204, thereby reinforcing the first stopper 201 and the second stopper 202 to withstand the external force of the valve handle 26. The first block 201 and the second block have stronger and durable effects.

As can be seen from the above, this creation has the following functions and advantages:

(1) The inner ring 204 is made thinner, thereby reducing the amount of the plastic formed by the inner ring 204, relatively increasing the plastic flow rate, and ensuring that the bonding line of the inner ring 204 is flatter, so that the copper mandrel 23 is The leakage preventing ring 231 between the pivot holes 203 has a better adhesion and achieves a practical effect of not leaking.

(2) The outer convex ring 205 assists in strengthening the first stopper 201 and the second stopper 202 to help withstand the impact force of the valve stem 26 and achieve the effect of being not easily damaged.

However, the above-mentioned ones are only preferred embodiments of the present invention, and are not intended to limit the features of the present creation. The re-creation of the technical means and creation principles related to the creation is still the creative equivalent of the creation. .

In summary, the structure of this creation does have excellent practicality and enhanced efficiency. It is in line with the provisions of the Patent Law, and it is submitted in accordance with the law.
